Diogo BS, Antunes SC, Rodrigues S. Are biopesticides safe for the environment? Effects of pyrethrum extract on the non-target species Daphnia magna. ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2023; 99:104114. [PMID: 37001686 DOI: 10.1016/j.etap.2023.104114] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/02/2022] [Revised: 03/21/2023] [Accepted: 03/28/2023] [Indexed: 06/19/2023]
Abstract
Biopesticides are natural compounds considered more safe and sustainable for the environment. However, it is also important to evaluate the potential risk in non-target organisms. Pyrethrum extract (PE) is a biopesticide, widely used for agriculture, veterinary, and aquaculture. This work aimed to evaluate acute (0.6 - 40.0 µg/L; 96 h; E(L)C50 toxicity) and sub-chronic (0.7 - 1.1 µg/L; 10 d; life-history parameters) effects of PE on Daphnia magna. Moreover, a biomarkers approach using antioxidant and biotransformation capacity, lipid peroxidation (LPO), neurotoxicity, and energy reserves content were evaluated. Acute effects (mortality, changes in swimming behavior, oxidative stress, lipid peroxidation, neurotoxicity) were recorded with the increase in PE concentration. Sub-chronic assay showed an increase in energy reserves content, antioxidant parameters, and LPO demonstrating that PE unbalances oxidative metabolism. This study can conclude that PE potentiates toxic effects in D. magna and demonstrates the vulnerability of a non-target organism to PE that is considered environmentally safe.

Ileriturk M, Kandemir FM. Carvacrol protects against λ-Cyhalothrin-induced hepatotoxicity and nephrotoxicity by modulating oxidative stress, inflammation, apoptosis, endoplasmic reticulum stress, and autophagy. ENVIRONMENTAL TOXICOLOGY 2023. [PMID: 36947485 DOI: 10.1002/tox.23784] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 03/07/2023] [Accepted: 03/12/2023] [Indexed: 06/18/2023]
Abstract
λ-Cyhalothrin, a type II synthetic pyrethroid, has been widely used in households, agriculture, public health, and gardening to control insect pests. Despite its widespread usage, it is known to induce a variety of adverse effects, including hepatotoxicity and nephrotoxicity. The goal of this study was to investigate the protective effect of carvacrol, which has antioxidant, anti-inflammatory, anti-apoptotic, and some other properties, on λ-Cyhalothrin-induced hepatotoxicity and nephrotoxicity 35 male Sprague-Dawley rats were randomly divided into five groups for this purpose: I-Control group: II-CRV group (50 mg/kg carvacrol), III-LCT group (6.23 mg/kg LCT), IV-LCT + CRV 25 group (6.23 mg/kg LCT + 25 mg/kg carvacrol), and V-LCT + CRV 50 group (6.23 mg/kg LCT + 50 mg/kg carvacrol). Using biochemical, real-time PCR, and western blotting methods, the collected tissues were analyzed. While λ-Cyhalothrin treatment increased MDA levels, which are indicated of lipid peroxidation, but reduced SOD, CAT, GPx activities, and GSH levels. After receiving carvacrol therapy, the degree of oxidative stress reduced as the values of these parameters approached those of the control group. Increased inflammation, apoptosis, endoplasmic reticulum stress, and autophagy with λ-Cyhalothrin administration reduced with carvacrol co-administration, and liver and kidney tissues were protected from damage, depending on the degree of oxidative stress. After considering all of these data, it was discovered that λ-Cyhalothrin-induced oxidative stress, inflammation, apoptosis, endoplasmic reticulum stress, and autophagy in the liver and kidneys; however, carvacrol protected the tissues from damage. Our findings indicate that carvacrol may be a promising protective agent in λ-Cyhalothrin-induced hepatotoxicity and nephrotoxicity.

Abstract
Background: Cypermethrin (Cyp) is a synthetic derivative of pyrethroids, implicated in various organ toxicity. This study investigated the potential cardio-protective activity of nano-piperine (NP) against Cyp toxicity in adult Wister male rats. Methods: All animals in groups II, III, IV, and V were subjected to Cyp (50 mg/kg) for 15 days. After 1 h of receiving the Cyp dose, 3 doses of NP (125, 250, and 500 µg/kg/day) were administered to groups III, IV, and V, respectively, for 10 days. In Group VI, a dose of 500 µg/kg NP alone was given orally daily for 10 days. Result: The toxic effects were evaluated by an increase in serum cardiac injury biomarkers (lactate dehydrogenase, cardiac troponin I, creatine kinase-myoglobin binding, tissue lipid peroxidation, a decrease in antioxidative activity, such as glutathione, superoxide dismutase [SOD] and catalase, and upregulation of interleukins [interleukin 1β, interleukin 6]). Immunohistochemistry studies of proteins (nuclear factor-κB [NF-kB], apoptotic protease activating factor-1 [Apaf-1], 4-hydroxynonenal [4-HNE] and Bax) showed enhanced expression, and histopathological examination revealed myolysis, loss of striation and hemorrhages indicating heart toxicity in the animals. Administration of NP significantly ameliorated all the changes caused by Cyp, such as a decrease in the levels of serum cardiac injury markers, an increase of antioxidative parameters, decrease in expression of inflammatory cytokines and NF-kB, Apaf-1, 4-HNE, and Bax, as shown by immunohistochemistry studies. Furthermore, all the histopathological changes were reduced to near the values of the control. Conclusion: Collectively our findings indicated that NP could be a potent nutraceutical exhibiting cardioprotective effects against Cyp-induced cardiotoxicity in rats.

Hepatoprotective Effect of Curcumin Nano-Lipid Carrier against Cypermethrin Toxicity by Countering the Oxidative, Inflammatory, and Apoptotic Changes in Wistar Rats. MOLECULES (BASEL, SWITZERLAND) 2023; 28:molecules28020881. [PMID: 36677938 PMCID: PMC9864069 DOI: 10.3390/molecules28020881] [Citation(s) in RCA: 9] [Impact Index Per Article: 9.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 11/23/2022] [Revised: 01/04/2023] [Accepted: 01/10/2023] [Indexed: 01/18/2023]
Abstract
This study investigated the potential hepatoprotective activity of curcumin-incorporated nano-lipid carrier (Cur-NLC) against cypermethrin (Cyp) toxicity in adult Wistar male rats. All animals in groups III, IV, V, and VI were subjected to Cyp (50 mg/kg) toxicity for 15 days. Three different doses of Cur-NLC (1, 2.5, and 5 mg/kg/day) were administered orally for 10 days. The toxic effects were evaluated considering the increases in serum hepatic biomarkers alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total protein and albumin, and lipid peroxidation (LPO), as well as a decrease in antioxidative activity (reduced glutathione (GSH), superoxide dismutase (SOD), and catalase) and the upregulation of inflammatory cytokines (IL-1β, IL-6, and TNF-α). Immunohistochemistry studies of proteins (NF-κB, Apaf-1, 4-HNE, and Bax) showed enhanced expression, and histopathological examination revealed architectural changes in liver cells, indicating liver toxicity in animals. Toxicity was determined by quantitative and qualitative determinations of DNA fragmentation, which show massive apoptosis with Cyp treatment. The administration of Cur-NLC significantly ameliorates all changes caused by Cyp, such as a decrease in the levels of serum liver markers, an increase in antioxidative parameters, a decrease in expression of inflammatory cytokines (IL-1β, IL-6, TNF-α, and NF-κB), and apoptosis (caspases-3, 9, Apaf-1, 4-HNE, and Bax), according to calorimetric and immunohistochemistry studies. The smear-like pattern of DNA is ameliorated similarly to the control at a high dose of Cur-NLC. Furthermore, all histopathological changes were reduced to a level close to the control. In conclusion, Cur-NLC could be a potent nutraceutical that exhibits a hepatoprotective effect against Cyp-induced hepatotoxicity in rats.

Abstract
BACKGROUND Permethrin is one of the pyrethroid insecticides, which is widely used in agriculture and public health. Although acute toxicity of the insecticide has been studied, the chronic toxicity upon the long-term exposure has not been clear yet. The purpose of the current study is to investigate the organ toxicities of permethrin following its long-term low-dose exposure. METHODS Male Wistar rats were daily administrated orally with permethrin (75 mg/kg body weight/day, gavage) for 90 days, and then the samples of biofluids (blood and urine) and organs including liver and kidney were collected. The serum and urine samples were measured by biochemical assay and the tissues of kidney and liver were examined and analyzed by histopathological method. RESULTS The results showed that no change was found in serum and urine biochemical parameters for the toxicity; however, significant changes including hyperchromatic nuclei swollen in the hepatic parenchymal cells and the swelling proximal tubules in the kidneys were observed in the tissue structures of liver and kidneys in the histopathological sections. CONCLUSION These results indicate that low-dose long-term exposure of permethrin can cause chronic toxicity with slight liver and kidney damage.

Evaluation of the Short-Term Toxic Effects of Chlorpyrifos and Cypermethrin on Selected Biomarkers in Common Carp ( Cyprinus carpio, Linnaeus 1758). TOXICS 2021; 9:toxics9060125. [PMID: 34072750 PMCID: PMC8229483 DOI: 10.3390/toxics9060125] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Revised: 05/20/2021] [Accepted: 05/27/2021] [Indexed: 01/02/2023]
Abstract
The general aim of this study was to investigate the negative short-term effects of different concentrations of chlorpyrifos (CPF) and cypermethrin (CYP), based on the EU legislation (MAC-EQS) in common carp (Cyprinus carpio Linnaeus, 1758) under laboratory conditions and to compare their toxicity. The fish were exposed to the pesticides for 96 h and then different histological and biochemical biomarkers were investigated in the gills and liver, and bioaccumulation analyses were conducted. The chemical studies showed increased pesticide concentrations in the gills as the first site for pollutants compared to the liver at the 96th hour. In addition, the histological analyses showed severe alterations in the gills and liver after exposure to both tested pesticides. In the gills, we found mainly intense proliferative and, to a lesser extent, degenerative changes and alterations in the circulatory system, such as necrosis and vasodilation. In the liver, regressive and progressive lesions, as well as circulatory disturbances and inflammation, were observed. The regressive lesions showed a higher degree of expression compared to the other changes. Furthermore, we found altered enzymatic activities—catalase, glutathione reductase, and glutathione peroxidase—in the liver, compared to the control. Overall, both tested pesticides impacted the studied biomarkers in common carp, even at concentrations lower than those permitted by law. However, the results of the comparative analysis showed a relatively higher toxicity of CYP compared to CPF in the fish. Still, questions persist as to whether the observed changes are adaptive or entirely destructive. To avoid any danger or risk, these pesticides must be applied cautiously, especially near water bodies.

Cypermethrin Impairs Hippocampal Neurogenesis and Cognitive Functions by Altering Neural Fate Decisions in the Rat Brain. Mol Neurobiol 2021; 58:263-280.

Abstract
Neurogenesis is a developmental process that involves fine-tuned coordination between self-renewal, proliferation, and differentiation of neural stem cells (NSCs) into neurons. However, early-life assault with environmental toxicants interferes with the regular function of genes, proteins, and other molecules that build brain architecture resulting in attenuated neurogenesis. Cypermethrin is a class II synthetic pyrethroid pesticide extensively used in agriculture, veterinary, and residential applications due to its low mammalian toxicity, high bio-efficacy, and enhanced stability. Despite reports on cypermethrin-mediated behavioral and biochemical alterations, till now, no study implicates whether cypermethrin exposure has any effect on neurogenesis. Therefore, the present study was undertaken to comprehend the effects of cypermethrin treatment on embryonic and adult neurogenesis. We found that cypermethrin exposure led to a considerable decrease in the BrdU/Sox-2+, BrdU/Dcx+, and BrdU/NeuN+ co-labeled cells indicating that cypermethrin treatment decreases NSC proliferation and generation of mature and functional neurons. On the contrary, the generation of BrdU/S100β+ glial cells was increased resulting in neurogliogenesis imbalance in the hippocampus. Further, cypermethrin treatment also led to an increased number of BrdU/cleaved caspase-3+ and Fluoro-Jade B+ cells suggesting an induction of apoptosis in NSCs and increased degeneration of neurons in the hippocampus. Overall, these results explicate that cypermethrin exposure not only reduces the NSC pool but also disturbs the neuron-astrocyte ratio and potentiates neurodegeneration in the hippocampus, leading to cognitive dysfunctions in rats.

Abstract
Pyrethroid insecticides are extensively used for control insects in both public health and agriculture sectors. Despite the important role of these insecticides, it caused adverse toxic effects on human, especially at the weanling stage. In this work, the antioxidant activity of chicory and artichoke leaves extracts, and phenolic flavonoid contents were studied. In addition, herbal syrup formulation and hepatoprotective effect against oxidative stress, lipid peroxidation, and liver damage induced by deltamethrin in weanling male rats were investigated. Both extracts have high phenolic, flavonoid contents, and antioxidant activity. Deltamethrin reduced body and liver weights of weanling rats. It induced oxidative stress, lipid peroxidation, and altered liver function enzymes. It caused a histopathological alteration in liver tissue. Supplementation of herbal syrup improved the above changes via increase body weights, antioxidant enzymes, and decrease lipid peroxidation, and enhanced histopathological profile. It can be concluded that herbal syrup of chicory and artichoke leaves extracts can ameliorate liver damage induced by deltamethrin. Herbal syrup from agriculture wastes of chicory and artichoke leaves is considered an easy, economical, and useful formulation for protecting agriculture workers against the adverse effects induced by pyrethroid insecticides especially in poor rural in developing countries where pyrethroid insecticides are applied for control vector-borne diseases and insects in agriculture.

Abstract
Background: Permethrin is a type of widely used pyrethroid pesticide. Although acute toxicity of permethrin has been well-characterised, the non-acute toxicity of permethrin upon long-term exposure at low dose has been seldom studied yet. The current study investigates the time-course change of the metabolomic profiles of urine following the low level long-term exposure of permethrin and identified biomarkers of the chronic toxicity of permethrin.Methods: Male Wistar rats were administrated orally with permethrin (75 mg/kg body weight/day, 1/20 LD50) daily for consecutive 90 days. The urine samples from day 30, day 60, and day 90 after the first dosing were collected and analysed by 1H NMR spectrometry. Serum biochemical analysis was also carried out.Results: Permethrin caused significant changes in the urine metabolites such as taurine, creatinine, acetate, lactate, dimethylamine, dimethylglycine, and trimethylamine-N-oxide. These biological markers indicated prominent kidney and liver toxicity induced by permethrin. However, there was no change in serum biochemical parameters for the toxicity, indicating that metabolomic approach was much more sensitive in detecting the chronic toxicity.Conclusion: The time-course alteration of metabolomic profiles of the urine based on 1H NMR reflects the progressive development of the chronic toxicity with the long-term low-level exposure of permethrin.

[PMID: 30419392 DOI: 10.1016/j.chemosphere.2018.10.217] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2018] [Revised: 10/29/2018] [Accepted: 10/30/2018] [Indexed: 06/09/2023]
Abstract
To find the adverse effects induced by cypermethrin, the ecotoxicological model copepods Tigriopus japonicus and Paracyclopina nana were exposed under cypermethrin, which is a widely used type-II pyrethroid insecticide in agriculture. Despite its large-scale application as insecticide in agriculture, little information is available on its adverse effects on aquatic invertebrates. In this study, the toxicity of cypermethrin on two copepods was assessed based on life parameters (growth rate and reproduction), oxidative stress and consequent antioxidant enzymatic activities, and gene expression profiles of antioxidants. The acute toxicity alone demonstrated that P. nana is less tolerant and sensitive against cypermethrin, compared to T. japonicus. However, under chronic exposure, life parameters of both P. nana and T. japonicus were severely affected by cypermethrin. Among antioxidant enzymatic activities, superoxide dismutase (SOD) and glutathione S-transferase (GST), in particular, demonstrated significant increase in response to cypermethrin. Furthermore, temporal-mRNA expression profile showed modulations in antioxidant related genes in response to cypermethrin. Our results provide the underlying toxic mechanism of cypermethrin and the oxidative stress defense mechanism and species-specific tolerance against cypermethrin in two model copepods species.

Mekircha F, Chebab S, Gabbianelli R, Leghouchi E. The possible ameliorative effect of Olea europaea L. oil against deltamethrin-induced oxidative stress and alterations of serum concentrations of thyroid and reproductive hormones in adult female rats. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2018; 161:374-382. [PMID: 29902617 DOI: 10.1016/j.ecoenv.2018.05.086] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2018] [Revised: 05/22/2018] [Accepted: 05/29/2018] [Indexed: 06/08/2023]
Abstract
This study aimed to verify whether Olea europaea L. (olive) oil (OEO) exerted a protective effect against oxidative stress induced by deltamethrin (DM) and alterations of pituitary, thyroid and gonadal hormones in adult female rats. DM (0,00256 g/kg body weight),OEO (0,6 g/kg body weight) and DM with OEO were administered to rats orally for 28 days. Volatile compounds present in olive oil were analysed by GC-MS. Estradiol (E2), Thyroxine (T4),Thyroid Stimulating Hormone (TSH), Triiodothyronine (T3), Follicle Stimulating Hormone (FSH), Luteinizing Hormone (LH), Progesterone (Pg) were measured in serum using Chemiluminescent Microparticle Immunoassay (CMIA). Lipid peroxidation (LPO), protein carbonyls (PCs), reduced glutathione (GSH) levels along with superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST) and glutathione peroxidase (GPx) activities were determined in thyroid and ovarian tissues. Sesquiterpenes, (E,E)-α-farnesene (16.45%) and α-copaene (9,86%), were analysed as the main volatile compounds of OEO. The relative weight of ovaries and thyroid and body weight significantly decreased in rats treated with DM. DM caused significant alterations in TSH, T4, FSH, Pg and E2 levels while T3 and LH concentrations remained unchanged when compared to control. DM also increased significantly LPO and PCs levels. In addition, GSH reserves as well as CAT, GPx, SOD and GST activities were suppressed in DM-received rats. The presence of OEO with DM returned the levels of oxidative stress markers, thyroid and reproductive hormones at the control values. Our results indicate that OEO is a powerful agent able to protect against DM oxidative stress and endocrine changes.

Abstract
The present study investigated the in vitro and the in vivo antioxidant capacities of Allium sativum (garlic) extract against deltamethrin-induced oxidative damage in rat's brain and kidney. The in vitro result showed that highest extraction yield was achieved with methanol (20.08%). Among the tested extracts, the methanol extract exhibited the highest total phenolic, flavonoids contents and antioxidant activity. The in vivo results showed that deltamethrin treatment caused an increase of the acetylcholinesterase level (AChE) in brain and plasma, the brain and kidney conjugated dienes and lipid peroxidation (LPO) levels as compared to control group. The antioxidant enzymes results showed that deltamethrin treatment induced a significantly decrease (p < 0.01) in brain and kidney antioxidant enzymes as catalase (CAT), superoxide dismutase (SOD) and glutathione peroxidase (GPx) to control group. The co-administration of garlic extract reduced the toxic effects in brain and kidney tissues induced by deltamethrin.

Abstract
Extensive use of synthetic pyrethroids has resulted in serious human health issues. Induction of oxidative stress is an important mechanism of action of most pesticides including pyrethroids. In the present study, we have elucidated the possible role of oxidative stress in bifenthrin-induced neurotoxicity. Adult male Wistar rats were administered bifenthrin (3.5 and 7 mg per kg body weight p.o.) for 30 days. Behavioral studies were conducted on a set of randomly selected rats from each treatment group after completion of treatment. Neurochemical parameters were assessed 24 h after the last dose was administered. The selected behavioral and neurochemical endpoints were also assessed 15 days after cessation of exposure to reveal whether the neurobehavioral changes produced by bifenthrin were temporary or permanent. Deficits in motor activity, motor incoordination, and cognitive impairment were observed after exposure to bifenthrin. Levels of biogenic amines viz. dopamine (DA) and its metabolites, i.e. 3,4-dihydroxyphenylacetic acid (DOPAC) and homovanillic acid (HVA), epinephrine (EPN), norepinephrine (NE), and serotonin (5-HT) altered in the frontal cortex, corpus striatum, and hippocampus of bifenthrin-treated rats. A decrease in the activity of acetylcholinesterase (AChE) occurred in all regions of the brain. Both doses of bifenthrin significantly induced lipid peroxidation (LPO) and increased protein carbonyl levels in the frontal cortex, corpus striatum, and hippocampus of rats. The activities of antioxidant enzymes, i.e. catalase, superoxide dismutase, and glutathione peroxidase, were also suppressed in all selected regions of the brain. A trend of recovery was, however, observed in all the behavioral and neurochemical endpoints 15 days after withdrawal of exposure. Oxidative stress seems to play an important role in bifenthrin-induced neurotoxicity. Our study suggests that long-term exposure to these compounds can produce detrimental effects.

Abstract
The extensive use of insecticides has hazardous effects since they can damage human health as well as the environment. Abamectin has been widely used in veterinary medicine and as a pesticide in agriculture. It is considered as one of the most commonly used insecticides in Egypt. The focus of the present study is to examine the toxic effects of sublethal dose (1 mg/kg b.wt.) of abamectin (Crater 3.37% EC) in male albino rats and to evaluate the efficiency of Eruca sativa suspension to ameliorate the abamectin toxicity. The present study was achieved using 18 male albino rats. Rats were divided into three groups: normal control group, abamectin-treated group, and abamectin + E. sativa-treated group. Rats of the third group were orally administrated a mixture of sublethal dose of abamectin (1 mg/kg b.wt.) and E. sativa suspension (5 g/kg b.wt.) three times a week for 28 days. At the end of the study period, blood samples were collected from all groups to measure the various hematological and biochemical parameters. The results revealed that rats, after abamectin exposure, exhibited general signs of toxicity and disturbance in the hematological and biochemical parameters. In addition, administration of E. sativa suspension ameliorated the hematological and biochemical parameters. These findings suggested that the exposure to abamectin might be responsible for hypertension, liver and kidney dysfunction, lipid profile disturbance, and oxidative stress, reflected in hematological and biochemical parameters. It was also found that the administration of E. sativa suspension reduced the detrimental impact of abamectin on some hematological and biochemical parameters.

Pyrethroid insecticide lambda-cyhalothrin and its metabolites induce liver injury through the activation of oxidative stress and proinflammatory gene expression in rats following acute and subchronic exposure. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2017; 24:5841-5856.

Abstract
Lambda-cyhalothrin (LTC) [α-cyano-3-phenoxybenzyl-3-(2-chloro-3,3,3-trifluoro-1-propenyl)-2,2-dimethylcyclo-propanecarboxylate] is a synthetic type II pyrethroid insecticide commonly used in residential and agricultural areas. The potential hepatotoxicity of pyrethroids remains unclear and could easily be assessed by measuring common clinical indicators of liver disease. To understand more about the potential risks for humans associated with LTC exposure, male adult rats were orally exposed to 6.2 and 31.1 mg/kg bw of LTC for 7, 30, 45, and 60 days. Histopathological changes and alterations of main parameters related to oxidative stress and inflammatory responses in the liver were evaluated. Further, lambda-cyhalothrin metabolites [3-(2-chloro-3,3,3-trifluoroprop-1-enyl)-2,2-dimethyl-cyclopropane carboxylic acid (CFMP), 4-hydroxyphenoxybenzoic acid (4-OH-3-PBA), and 3-phenoxybenzoic acid (3-PBA)] in the liver tissues were identified and quantified by ultra-high-performance liquid chromatography coupled to quadripole time-of-flight mass spectrometry (UHPLC-MS-Q-ToF). Results revealed that LTC exposure significantly increased markers of hepatic oxidative stress in a time-dependent and dose-dependent manner, and this was associated with an accumulation of CFMP and 3-PBA in the liver tissues. In addition, the levels of tumor necrosis factor-α (TNF-α) and interleukin (IL-6 and IL-1β) gene expressions were significantly increased in the liver of exposed rats compared to controls. Correlation analyses revealed that CFMP and 3-PBA metabolite levels in the liver tissues were significantly correlated with the indexes of oxidative stress, redox status, and inflammatory markers in rats exposed to lambda-cyhalothin. Overall, this study provided novel evidence that hepatic damage is likely due to increased oxidative stress and inflammation under the condition of acute and subchronic exposure to lambda-cyhalothrin and that LTC metabolites (CFMP and 3-PBA) could be used as potential biomarker in human biomonitoring studies.

Abstract
The adverse effect of cypermethrin on the liver and kidney of weanling female rats and the protective effect of ethanolic extract of grape pomace were investigated in the present study. Weanling female rats were given cypermethrin oral at a dose of 25 mg kg−1 body weight for 28 consecutive days. An additional two Cyp-trated groups received extract at a dose of 100 and 200 mg kg−1 body weight, respectively, throughout the experimental duration. Three groups more served as extract and control groups. Administration of Cyp resulted in a significant increase in serum marker enzymes, for example, aminotransferases (AST and ALT), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT), and increases the level of urea nitrogen and creatinine. In contrast, Cyp caused significant decrease in levels of total protein and albumin and caused histopathological alterations in liver and kidneys of female rats. Coadministration of the extract to Cyp-treated female rats restored most of these biochemical parameters to within normal levels especially at high dose of extract. However, extract administration to Cyp-treated rats resulted in overall improvement in liver and kidney damage. This study demonstrated the adverse biohistological effects of Cyp on the liver and kidney of weanling female rats. The grape pomace extract administration prevented the toxic effect of Cyp on the above serum parameters. The present study concludes that grape pomace extract has significant antioxidant and hepatorenal protective activity.

Abstract
Background The aim of this study was to investigate the protective effects of L-glutamine (GLN) against liver and kidney injury caused by acute toxicity of deltamethrin (DLM). Material/Methods Thirty-two rats were indiscriminately separated into 4 groups with 8 rats each: control group (distilled water; 10 ml/kg, perorally [p.o.]), DLM group (35 mg/kg p.o. one dose.), GLN group (1.5 gr/kg, p.o. single dose.) and DLM (35 mg/kg p.o. one dose.) + GLN group (1.5 gr/kg, p.o. one dose after 4 hours.). Testing for total antioxidant status (TAS), total oxidant status (TOS), interleukin-1 beta (IL-1β), tumor necrosis factor-alpha (TNF-α), and interleukin-6 (IL-6) analyses were performed on tissue samples, and alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), urea, and creatinine were analyzed on serum samples. Liver and kidney samples were histopathologically analyzed. Results The TOS level in liver was significantly higher in the DLM group than in the control group, and the level in DLM+GLN group was considerably lower than in the DLM group. The TAS level in the DLM+GLN group was considerably higher than in the control and DLM groups. The TAS level in kidney tissues was considerably lower in the DLM group than in controls, but was similar to other groups. Histopathological analyses of liver tissues established a significant difference between DLM and DLM+GLN groups in terms of grade 2 hepatic injury. However, no significant difference was found between DLM and DLM+GLN groups in terms of kidney injury. Conclusions Glutamine leads to significant improvement in deltamethrin-induced acute hepatotoxicity in terms of histopathologic results, tissue oxidative stress parameters, and serum liver function marker enzymes.

Abstract
Spirulina platensis (SP) is one of the most commonly used dietary supplements in human and many animal species, including fish. Recently, it has gained more attention in fish not only for its growth-promoting and immunomodulatory effects but also for its antioxidant potential. The present study was conducted to investigate the protective role of two different dietary levels of SP on freshwater Nile tilapia; Oreochromis niloticus exposed to subacute deltamethrin (DLM) intoxication. Spirulina was supplemented at levels of 0.5 and 1 % in the diet along with DLM at a concentration of 1.46 μg/l for 28 days. Serum biochemical parameters, alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), total protein, albumin, cholesterol, urea, uric acid and creatinine, were estimated. In addition, the level of malondialdehyde (MDA) was analysed as a lipid peroxidation marker. Reduced glutathione (GSH) content and glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT) activities were analysed as antioxidant biomarkers in liver, kidney and gills. The results revealed that DLM intoxication increased serum AST, ALT, ALP, cholesterol, urea, uric acid, creatinine and tissue MDA, while decreased serum total protein and albumin as well as tissue GSH level and GSH-Px, SOD and CAT activities. SP supplementation at the two tested levels enhanced all altered serum biochemical parameters as well as tissue lipid peroxidation and antioxidant biomarkers. Therefore, it could be concluded that SP administration could minimize DLM-induced toxic effects by its free radical scavenging and potent antioxidant activity.

Abstract
This study was designed to investigate the possibility of β-cyfluthrin to induce oxidative stress and biochemical perturbations in rat liver and the role of selenium in alleviating its toxic effects. Male Wister rats were randomly divided into four groups of seven each, group I served as control, group II treated with selenium (200 µg/kg BW), group III received β-cyfluthrin (15 mg/kg BW, 1/25 LD50 ), and group IV treated with β-cyfluthrin plus selenium. Rats were orally administered their respective doses daily for 30 days. The administration of β-cyfluthrin caused elevation in lipid peroxidation (LPO) and reduction in the activities of antioxidant enzymes including catalase (CAT), superoxide dismutase (SOD), glutathione S-transferase (GST), glutathione peroxidase (GPx), and glutathione reductase (GR). A decrease in reduced glutathione (GSH) content was also observed. Liver aminotransferases (AST and ALT) and alkaline phosphatase (ALP) were decreased, whereas lactate dehydrogenase (LDH) was increased. Selenium in β-cyfluthrin-induced liver oxidative injury of the rats modulated LPO, CAT, SOD, GSH, GST, GPx, and GR. Also, liver AST, ALT, ALP, and LDH were maintained near normal level due to selenium treatment. It is concluded that selenium scavenges reactive oxygen species and render a protective effect against β-cyfluthrin toxicity.

This study was carried out to evaluate the adverse effects of exposure to prallethrin on oxidant/antioxidant status and liver dysfunction biomarkers and the protective role of Origanum majorana essential oil (EO) in rat. Male rats were divided into 4 groups: (i) received only olive oil (ii) treated with 64.0 mg/kg body weight prallethrin (1/10 LD50) in olive oil via oral route daily for 28 days, (iii) treated with 64.0 mg/kg body weight prallethrin (1/10 LD50) and EO (160 μL/kg b.wt.) in olive oil and (iv) received EO (160 μL/kg b.wt.) in olive oil via oral route twice daily for 28 days. Prallethrin treatment caused decrease in body weight gain and increase in relative liver weight. There was a significant increase in the activity of serum marker enzymes, aspartate transaminase, alanine transaminase, and alkaline phosphatase. It caused increase in thiobarbituric acid reactive substances and reduction in the activities of superoxide dismutase, catalase, and glutathione-S-transferase in liver. Consistent histological changes were found in the liver of prallethrin treatment. EO showed significant protection with the depletion of serum marker enzymes and replenishment of antioxidant status and brought all the values to near normal, indicating the protective effect of EO. We can conclude that prallethrin caused oxidative damage and liver injury in male rat and co-administration of EO attenuated the toxic effect of prallethrin. These results demonstrate that administration of EO may be useful, easy, and economical to protect human against pyrethroids toxic effects.

Abstract
The aim of this study was to investigate the ameliorative properties of lycopene against the toxic effects of cypermethrin (CYP) by examining oxidative damage markers such as lipid peroxidation and the antioxidant defense system components in carp (Cyprinus carpio). The fish were divided into seven groups of 10 fish each and received the following treatments: group 1, no treatment; group 2, orally administered corn oil; group 3, oral lycopene (10 mg/kg body weight); group 4, exposure to 0.202 μg/L CYP; group 5, exposure to 0.202 μg/L CYP plus oral administration of 10 mg/kg lycopene; group 6, exposure to 0.404 μg/L CYP; and group 7, exposure to 0.404 μg/L CYP plus oral administration of 10 mg/kg lycopene. Treatment was continued for 28 days, and at the end of this period, blood and tissue (liver, kidney, and gill) samples were collected. Levels of malondialdehyde (MDA) and reduced glutathione (GSH) as well as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities were determined in blood and tissues for measurement of oxidant-antioxidant status. MDA level, as an index of lipid peroxidation, increased in blood and tissues. Antioxidant enzyme activities in blood and tissues were modified in CYP groups compared with controls. Administration of lycopene ameliorated these parameters. The present results suggest that administration of lycopene might alleviate CYP-induced oxidative stress.

Abstract
Type I and II pyrethroid insecticides display different neurotoxicity. To investigate the long-term (60 days exposure) metabolic effect of the two types of pyrethroid insecticides deltamethrin and permethrin, (1)H nuclear magnetic resonance (NMR) spectroscopy-based metabonomics was used to analyze the biochemical composition of urine and serum samples from rats administrated daily with deltamethrin or permethrin for 60 consecutive days, and principal component analysis used to visualize similarities and differences in the resultant biochemical profiles. Rats treated with either deltamethrin or permethrin displayed increased levels of urinary acetate, dimethylamine, dimethylglycine, trimethylamine and serum free amino acids, and decreased urinary 2-oxoglutarate, all of which are indicative of kidney lesions and nephrotoxicity. The reduced excretion of tricarboxylic acid cycle intermediates, together with increased 3-D-hydroxybutyrate, acetate, and lactate in treated rats could suggest disturbance of the energy metabolism, including an increased rate of anaerobic glycolysis, enhanced fatty acid β-oxidation and ketogenesis. These results show that these two types of insecticides have similarities in the urine and serum spectra, indicating that similar metabolic pathways are perturbed by the insecticides, which induced hepatotoxicity and nephrotoxicity. This approach may lead to the discovery of novel biomarkers of pyrethroids toxicity and thereby provide new insights into the toxicological mechanisms of pesticides pyrethroids.

Abstract
Deltamethrin is a broad-spectrum synthetic pyrethroid insecticide and acaricide widely used for agricultural and veterinary purposes. However, its human and animal exposure leads to hepatonephrotoxicity. Therefore, the present study was undertaken to examine the hepatonephroprotective and antioxidant potential of Spirulina platensis against deltamethrin toxicity in male Wistar albino rats. Deltamethrin treated animals revealed a significant increase in serum biochemical parameters as well as hepatic and renal lipid peroxidation but caused an inhibition in antioxidant biomarkers. Spirulina normalized the elevated serum levels of AST, ALT, APL, uric acid, urea and creatinine. Furthermore, it reduced deltamethrin-induced lipid peroxidation and oxidative stress in a dose dependent manner. Therefore, it could be concluded that spirulina administration able to minimize the toxic effects of deltamethrin by its free radical-scavenging and potent antioxidant activity.

Abstract
The joint action of pyrethroids, lambda-cyhalothrin (LC) in combination with organophosphates, fenitrothione (FNT) on antioxidant defense system and lipid peroxidation biomarkers in rat testes was studied. The results suggest that incubation of testes homogenate with different concentrations of insecticide mixture for different time intervals significantly decreased the activity of antioxidant enzymes, like glutathione S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT), and the level of reduced glutathione (GSH). In addition, a significant inhibition in transaminases (AST, ALT), phosphatases (AcP, AlP) activity and protein content were observed. On the other hand, FNT plus LC increased the cellular lipid peroxidation (LPO) level and the activity of lactate dehydrogenase (LDH). In conclusion, the use of insecticides mixture might cause marked oxidative damage in a concentration and time-dependent manner.

Abstract
In this study, toxic effects of the cypermethrin in Allium cepa L. cells were investigated. For this aim, we investigated the changes in pigment contents, antioxidant enzymes, mitotic index and chromosomal abnormalities as indicators of toxicity. The seeds were treated with different doses (1.5, 3.0, 6.0 ppm) of cypermethrin for 72 h. The result showed that there was a significant alteration in the tested parameters depending on treatment dose in the seeds exposed to cypermethrin when compared to the control group. Cypermethrin exposure significantly reduced the carotenoid, chlorophyll a and b pigments in all treatment groups. The activity of superoxide dismutase showed a concentration-time dependent increase and the maximum increase was observed on day 15 of treatment at 6.0 ppm cypermethrin exposure. The activity of catalase increased gradually with increasing cypermethrin concentration, but a soft decrease in CAT activity was decreased after 15 days of 1.5 ppm and 3.0 ppm cypermethrin treatment. In the roots treated with 1.5, 3.0, and 6.0 ppm cypermethrin, the level of malondialdehyde was about 1.8, 2.4, and 3.4 times higher than the control group, respectively. It was also found that cypermethrin has a mitodepressive action on mitosis, and the MI was decreased depending on the dose of cyprmethrin. All of the concentrations of cypermethrin induced chromosomal abnormalities and the most common abnormality observed in the present study was chromosome bridges.

Abstract
This study is focused on understanding the mechanism of neurobehavioral toxicity of lambda-cyhalothrin, a new generation type II synthetic pyrethroid in developing rats following their exposure from post-lactational day (PLD)22 to PLD49 and investigate whether neurobehavioral alterations are transient or persistent. Post-lactational exposure to lambda-cyhalothrin (1.0 or 3.0 mg/kg body weight, p.o.) affected grip strength and learning activity in rats on PLD50 and the persistent impairment of grip strength and learning was observed at 15 days after withdrawal of exposure on PLD65. A decrease in the binding of muscarinic-cholinergic receptors in frontocortical, hippocampal, and cerebellar membranes associated with decreased expression of choline acetyltransferase (ChAT) and acetylcholinesterase (AChE) in hippocampus was observed following exposure to lambda-cyhalothrin on PLD50 and PLD65. Exposure to lambda-cyhalothrin was also found to increase the expression of growth-associated protein-43 in hippocampus of rats on PLD50 and PLD65 as compared to controls. A significant increase in lipid peroxidation and protein carbonyl levels and decreased levels of reduced glutathione and activity of superoxide dismutase, catalase, and glutathione peroxidase in brain regions of lambda-cyhalothrin exposed rats were distinctly observed indicating increased oxidative stress. Inhibition of ChAT and AChE activity may cause down-regulation of muscarinic-cholinergic receptors consequently impairing learning activity in developing rats exposed to lambda-cyhalothrin. The data further indicate that long-term exposure to lambda-cyhalothrin at low doses may be detrimental and changes in selected behavioral and neurochemical end points may persist if exposure to lambda-cyhalothrin continues.

Abstract
A mixture of pyrethroids plus organophosphates was assessed for their potential effects on lipid peroxidation, the antioxidant defense system and lactate dehydrogenase (LDH) in rat kidney in vitro. Various insecticide concentrations were incubated with kidney homogenate at 37°C for different incubation times. Treatment with fenitothion (FNT) plus lambda-cyhalothrin (LC) caused a significant induction (P < 0.05) in thiobarbituric acid reactive substances (TBARS), which might be associated to decreased levels of reduced glutathione (GSH), superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST) activities and protein content in rat kidney. However, a significant induction of lactate dehydrogenase (LDH) activity was observed. The effect was concentration and time dependent. It can be concluded that depletion of GSH might indicate that reactive oxygen species (ROS) could be involved in the toxic effects of FNT plus LC which lead to marked perturbations in antioxidant defense system.

Abstract
Carbaryl is used in Indian agriculture for control of rice field pests and it is next to Benzene hexachloride in pesticide consumption. In present study, carbaryl (0, 10, 20, 30 and 40 mg/L) induced toxic effects were observed after 21 days exposure on a non target rice field biofertilizer Calothrix brevissima with special reference to oxidative stress, antioxidant enzymes and osmolytes. At 40 mg/L carbaryl the decrease in carotenoid, chlorophyll, phycobilin and protein were 63%, 43%, 40% and 40% respectively in comparison to control. Total carbohydrate, malondialdehyde, superoxide dismutase, ascorbate peroxidase, catalase and osmolytes showed enhancement at all the treated concentration. Increased amount of MDA (46% at 40 mg/L) indicated free radical mediated deleterious effect of carbaryl. Enhancement of SOD, APX, CAT and osmolytes in presence of carbaryl indicated their involvement in free radical scavenging. SOD, CAT and APX showed maximum activities (79%, 64% and 39% respectively) at 40 mg/L carbaryl. The order of enhancement in osmolytes was glycine-betaine (66%) > proline (54%) > sucrose (50%) at 40 mg/L which might be another adaptive defense strategy of the cyanobacterium against the pesticide.

Abstract
Lambda-cyhalothrin (LTC) is a synthetic pyrethroid with a broad spectrum of insecticidal and acaricidal activities used to control wide range of insect pests in a variety of applications. The aim of this study was to examine (i) the potency of LTC to induce oxidative stress response in rat erythrocytes in vitro and (ii) the role of caffeic acid (20 μM) and/or quercetin (10 μM) in preventing the cytotoxic effects. Erythrocytes were divided into four portions. The erythrocytes of the first portion were incubated for 4 h at 37°C with different concentrations (0, 50 and 100 μM) of LTC. The others portions were pretreated with caffeic acid and/or quercetin for 30 min prior to LTC incubation. Lipid peroxidation, protein oxidation, antioxidant enzyme activities and DNA damage were examined. LTC at different concentrations causes increased levels of lipid peroxidation, protein oxidation, DNA damage and decreased antioxidant enzyme activities. Combined caffeic acid and quercetin pretreatments significantly reduced the levels of lipid peroxidation markers, that is thiobarbituric acid reactive substance (TBARS), protein carbonyls (PCO) and decreased DNA damage in LTC portion. Further, combined caffeic acid and quercetin pretreatment maintain antioxidant enzyme activities and glutathione content near to normal values. These results suggest that LTC exerts its toxic effect by increasing lipid peroxidation, altering the antioxidant enzyme activities and DNA damage. Caffeic acid and quercetin pretreatments prevent the toxic effects of LTC, suggesting their role as a potential antioxidant.

Abstract
Fenvalerate, a type II synthetic pyrethroid, has emerged as one of the most potent indoor toxicants. Despite its widespread usage, the adverse effect of this insecticide on immune defense mechanism has not been comprehensively investigated. In this in vitro study we report the effect of fenvalerate on two pivotal components of the immune network, namely the complement system and macrophages. Fenvalerate treated human sera showed serum complement activation as evident by significant (p<0.05) increase in C3b, C3d and C3a levels and a significant (p<0.05) decline in CH50 levels. Further detailed study demonstrates that the activation of complement system is through alternative pathway. This is possibly responsible for various allergic manifestations often reported in subjects exposed to fenvalerate. In addition, fenvalerate induce cellular apoptosis and cytotoxicity, as demonstrated by cytoplasmic vacuolization, heterochromatin condensation, hypodiploid nuclei and DNA fragmentation in macrophages. Considerable deleterious effects on macrophages in conjunction with uncontrolled serum complement activation are probably one of the major mechanisms contributing for the immunosuppressive effects of fenvalerate.

Abstract
The aim of present study was to investigate the protective effect of curcumin on cypermethrin-induced changes in blood biochemical markers and tissue antioxidant enzyme in rats. Rats were divided into six groups of six each: group I used as control and II and III groups were used as vehicle control. While, groups IV, V and VI were orally treated with curcumin (100 mg/kg body weight), cypermethrin (25 mg/kg body weight) and cypermethrin plus curcumin, respectively for 28 days. Serum biochemical markers were measured in the serum, and the levels of lipid peroxidation and antioxidant enzyme activity were determined in the liver, kidney and brain. Cypermethrin administration caused elevated level of blood biochemical markers in serum and lipid peroxidation in liver, kidney and brain. While the activities of non-enzymatic and enzymatic antioxidants levels were decreased except superoxide dismutase in liver, kidney and brain tissues. The presence of curcumin with cypermethrin significantly decreased the blood biochemical markers and lipid peroxidation but significantly increased the reduced glutathione, catalase and glutathione peroxidase level and preserved the normal histological architecture of the liver, kidney and brain. Our results indicate that curcumin can be potent protective agent against cypermethrin-induced biochemical alterations and oxidative damage in rats.

Abstract
Risk assessment of man-made chemicals such as pesticides are mainly focused on parent compounds, and relatively little is known about their metabolites, especially with regard to target organ damages such as immunotoxicity. In the present study, the immunotoxicity of five synthetic pyrethroids (SPs) and three common metabolites was evaluated using an in vitro model by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, cytoflow, and enzyme-linked immunosorbent assay (ELISA). Cell viability and apoptosis assays showed that both SPs and their metabolites possessed cytotoxicity to the monocytic cells. The aldehyde and acid derivatives were more effective than the other compounds at cytotoxicity, with inhibition of cell viability by 56.8 and 50.6% at 10⁻⁵ mol L⁻¹, and induction of 8.52 and 8.81% cell apoptosis, respectively. Exposure to SPs and their metabolites also led to changes in the secretion levels of tumor necrosis factor α (TNF α) and interleukins (ILs), and again the metabolites showed stronger effects than the parent compounds. The aldehyde derivative upregulated IL-12p70 level by 1.87-fold, and the alcohol and acid derivative increased the secretion of TNF α 5.88 and 7.96-fold, relative to the control group. In the in vitro model, the common metabolites of SPs clearly exerted greater immunotoxic effects to monocytes than the intact parent compounds. Results from the present study suggested the need for considering metabolites in achieving more comprehensive health risk assessment of man-made chemicals, including target organ toxicities such as immunotoxicity.

Abstract
Heat shock proteins (Hsp) are a family of stress proteins, which are elicited in response to a variety of stressors in organisms. The objective of this study was to explore the potential of cypermethrin, a synthetic pyrethroid insecticide, on induction of small heat shock proteins (Hsp16) and feeding response in transgenic Caenorhabditis elegans PC72 (Hsp16-LacZ). A concentration-dependent inhibition in feeding was evident in worms exposed to cypermethrin (31%, 46% and 56% at 5, 10, 15 mM, respectively) beyond 4h while marked induction of heat shock protein-16 expression was evident after 12h exposure (as evident from quantitative analysis). Maximum expression of Hsp16 was observed throughout the body of the worms 24h after exposure similar to that evident in the worms exposed to heat shock at 30 degrees C. These data suggest that cypermethrin possesses the potential to induce Hsp16 as well as inhibit feeding in C. elegans at non-lethal concentrations. C. elegans (PC72) thus could serve as a convenient model to study the early toxic effects of xenobiotics.

Toxicol In Vitro 2009; 24:879-84. [PMID: 19961921 DOI: 10.1016/j.tiv.2009.11.022] [Citation(s) in RCA: 29] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2009] [Revised: 11/25/2009] [Accepted: 11/27/2009] [Indexed: 11/16/2022]
Abstract
beta-Cyfluthrin is one of the most widely used type II pyrethroid in agriculture. The aim of this study was to examine (1) the possibility of beta-cyfluthrin to induce oxidative stress in human erythrocytes in vitro and its effect on catalase (CAT) and superoxide dismutase (SOD) activities as well as (2) the role of melatonin (MEL; 2mM), its precursor--N-acetylserotonin (NAS; 1mM), quercetin (Q; 80 microM) and rutin (R; 80 microM) in alleviating the cytotoxic effects of beta-cyfluthrin. Erythrocytes were divided into portions. The first portion was incubated for 4h at 37 degrees C with different concentrations (0, 43, 215, 1075 ppm) of beta-cyfluthrin. The other portions were preincubated with selected antioxidant, respectively for 30 min and followed by beta-cyfluthrin incubation for 4h. Malondialdehyde (MDA) concentrations, CAT and SOD activities, as well as haemolysis percentage (H) were measured in all treatment portions of erythrocytes. It could be concluded that the in vitro toxicity of beta-cyfluthrin may be associated with oxidative stress. Significant reduction in the activities of CAT was observed at all beta-cyfluthrin concentrations, while SOD activities were significantly decreased only in erythrocytes incubated with the highest beta-cyfluthrin concentration. SOD activity of the non-pretreated erythrocytes exposed to the lowest dose of beta-cyfluthrin was significantly greater when compared to comparably beta-cyfluthrin-exposed antioxidant pretreated cells. The highest concentration of beta-cyfluthrin has caused over 35% haemolysis, and the lowest concentration about 15%. MEL pretreatment had no effect on H and MDA induction by beta-cyfluthrin. NAS, Q and R reduced H and MDA level, but could not prevent induction of these parameters. Compared to other antioxidants NAS appeared to maintain better the CAT activity at control levels for all doses of beta-cyfluthrin. Pretreatment with Q was found to protect against the decrease in SOD activity induced by beta-cyfluthrin.

Abstract
AbstractThe cytotoxic and protective effects of selected synthetic chalcone analogues have been shown in previous studies. We studied their cytotoxic effect on the modification of mitochondrial membrane potential and on DNA. The first spectral information about the methoxy group as well as the dimethylamino substituent in E-2-arylmethylene-1-benzosuberones molecule was obtained by absorption and emission spectra. The cytotoxic effect of both cyclic chalcone analogues on DNA were detected by alkaline single-cell gel electrophoresis. Better fluorescent chalcone analogue E-2-(4′-dimethylamino-benzylidene)-1-benzosuberone was studied further in fresh isolated mitochondria. The decrease of rat liver mitochondria membrane potential (Δψ) was observed by fluorescence emission spectra. For the collapsing of mitochondrial potentials and as the negative control of mitochondrial function the CCCP uncoupler was used. The absorption maximum of the methoxy group was found at a shorter wavelength (λ = 335 nm) than that of the dimethylamino group (λ = 406 nm). The excitation spectra were very similar to the absorption spectra for both molecules but the emission spectra showed a better fluorescence for dimethylamino derivative. After the addition of E-2-(4′-dimethylamino-benzylidene)-1-benzosuberone to the intact mitochondria the decrease of mitochondrial membrane potential Δψ was observed by emisssion fluorescence spectra. Both cyclic chalcone analogues induced DNA damage, which was detected by alkaline comet assay. Mainly the apoptotic cells were detected, but necrotic cells were also present. Similarities in the percentages of DNA migration from the head were observed in both treatment groups. Both benzosuberones, with dimethylamino- and methoxy- substituent, were very active biologically, as shown by DNA results of the comet assay. Due to its better fluorescence properties, only the fluorophore with dimethylamino substituent was selected for further study of the function of rat liver mitochondria. Decline of mitochondrial function as well as mitochondrial DNA damage were evident between experimental and control groups.

Abstract
The objective of this study was to investigate the propensity of lambda-cyhalothrin (LTC) to induce oxidative stress in blood and brain of male Wistar rats and its possible attenuation by vitamin C. Rats were randomly divided into four groups: group I served as control rats. group II was treated daily with 200mgvit C/(kgbw) administered by intraperitoneal way. Rats of group III have received orally 668ppm LTC. Animals of group IV were treated with LTC and vitamin C. A decrease of some hematologic parameters (RBC, Hb, Ht: p<0.01) and a significant increase of MDA levels (p<0.05) in erythrocytes and brain were observed in LTC group compared to controls. Antioxidant enzyme activities in both tissues were modified in LTC group compared to controls. Administration of vitamin C ameliorated these parameters. Our results indicated the potential effects of LTC to induce oxidative damage in tissues and the ability of vitamin C to attenuate LTC-induced oxidative damage.

Abstract
Tetrabromobisphenol A (TBBPA) is one of the most widely used members of the family of brominated flame retardants (BFRs). BFRs, including TBBPA have been shown to be widely distributed within the environment and there is growing evidence of their bio-accumulation within animals and man. Toxicological studies have shown that TBBPA can be harmful to cells by modulating a number of cell signalling processes. In this study, we employed fluorescence spectroscopy and differential scanning calorimetry to investigate the interaction of TBBPA with phospholipid membranes, as this is the most likely route for it to influence membrane-associated cellular processes. TBBPA readily and randomly partitions throughout all regions of the phospholipid bilayer with high efficacy [partition coefficient (Log K(p))=5.7+/-0.7]. A decrease in membrane fluidity in both liquid-crystalline and gel-phase membranes was detected at concentrations of TBBPA as low as 2.5 microM. TBBPA also decreases the phase transition temperature of dipalmitoyl phoshatidylcholine (DPPC) membranes and broadened transition peaks, in a fashion similar to that for cholesterol. TBBPA, however, also prefers to partition into membrane regions not too highly enriched with cholesterol. Our findings therefore suggests that, the toxic effects of TBBPA, may at least in part, be due to its lipid membrane binding/perturbing effects, which in turn, could influence biological processes involving cell membranes.

Abstract
Erythrocytes are a convenient model to understand the membrane oxidative damage induced by various xenobiotic-prooxidants. This study was designed to investigate (1) the possibility of lambda-cyhalothrin (LC), a type II pyrethroid, to induce oxidative stress response in rabbit erythrocytes in vitro and its effect on selected antioxidant enzymes and (2) the role of vitamin C (VC; 20mM) and vitamin E (VE; 2mM) in alleviating the cytotoxic effects of LC. Erythrocytes were divided into three groups. The first group, previously prepared erythrocytes was incubated for 4h at 37 degrees C with different concentrations (0, 0.1, 0.5, 1, 2.5, 5mM) of LC. The second and third groups were preincubated with VC or VE, respectively for 20 min and followed by LC incubation for 4h. Following in vitro exposure, LC caused a significant induction of oxidative damage in erythrocytes at different concentrations as evidenced by increased thiobarbituric acid reactive substances (TBARS) levels. However, a significant decrease in the content of sulfhydryl groups (SH-groups), and the activities of acetylcholinesterase (AChE), superoxide dismutase (SOD), catalase (CAT) and glutathione S-transferase (GST) were observed. The response was concentration dependent. VC or VE pretreated erythrocytes showed a significant protection against the cytotoxic effects induced by LC on the studied parameters. In conclusion, antioxidant vitamins especially VE could be able to ameliorate LC-induced oxidative stress by decreasing lipid peroxidation and altering antioxidant defense system in erythrocytes.

Abstract
Deltamethrin is a synthetic pyrethroid insecticide used worldwide in agriculture, home pest control, protection of foodstuff and disease vector control. The objective of this study was to investigate the propensity of deltamethrin to induce oxidative stress and changes in biochemical parameters and enzyme activities in male rats following a short-term (30 days) oral exposure and its possible attenuation by Vitamin E (Vit. E). Rats were assigned to 1 of 4 treatment groups: 0mg Vit. E and 0mg deltamethrin/kg body weight (BW) (control); 100mg Vit. E/kg BW; 1.28mg deltamethrin/kg BW; 100mg Vit. E plus 1.28mg deltamethrin/kg BW. Results obtained showed that deltamethrin significantly (P<0.05) induced thiobarbituric acid-reactive substances (TBARS; the marker of lipid peroxidation) in plasma. The activities of glutathione S-transferase (GST) and superoxide dismutase (SOD) were significantly decreased due to deltamethrin administration. On the other hand, treatment with Vitamin E alone increased the activities of GST and SOD, and decreased the levels of TBARS. Also, Vitamin E alleviated the harmful effect of deltamethrin in the combination group. Enzymatic activities of aminotransferases (AST and ALT), phosphatases (AcP and AlP) and lactate dehydrogenase (LDH) in plasma were significantly increased, while acetylcholinesterase (AChE) was inhibited. Deltamethrin significantly (P<0.05) increased the levels of plasma total lipid (TL), cholesterol, triglyceride (TG), low density lipoprotein (LDL) and very low density lipoprotein (VLDL), while the level of high density lipoprotein (HDL) decreased. Vitamin E alone decreased the levels of lipids and lipoproteins, and alleviated the harmful effects of deltamethrin. Concentrations of glucose, urea, creatinine and total bilirubin were increased. While, plasma total protein (TP), albumin (A) and globulin (G) were significantly (P<0.05) decreased. The present study revealed that the presence of Vitamin E could diminish the adverse effects of deltamethrin on most of biochemical parameters, lipid peroxidation and enzyme activities in rats.
