Abstract
Cypermethrin (CYP) is an insecticide in the pyrethroid family and is used widely in agriculture and for public health purposes. However, CYP has been shown to have negative impacts on reproduction, immunity and nerves in mammals. In this study, a monoclonal antibody (mAb) against CYP was prepared and used to establish an indirect competitive immunosorbent assay (ic-ELISA) and colloidal gold lateral flow immunoassay (LFIA) for the quantitative and qualitative determination of CYP residues in agricultural products. The half inhibition concentration of the ic-ELISA was 2.49 ng/mL, and the cut-off value and visual limit of detection of the LFIA were 0.6 and 0.3 μg/mL, respectively. The recovery rates of the ic-ELISA ranged from 78.8% to 87.6% in tomato, cabbage and romaine lettuce. The qualitative results of LFIA and quantitative results of ic-ELISA and HPLC were in good agreement in blind samples. Overall, the established ic-ELISA and LFIA proved to be accurate and rapid methods for the determination of CYP in agricultural products.

Lifetime Pesticide Use and Monoclonal Gammopathy of Undetermined Significance in a Prospective Cohort of Male Farmers. ENVIRONMENTAL HEALTH PERSPECTIVES 2021; 129:17003. [PMID: 33404262 PMCID: PMC7787072 DOI: 10.1289/ehp6960] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/21/2020] [Revised: 11/06/2020] [Accepted: 12/04/2020] [Indexed: 05/15/2023]
Abstract
BACKGROUND Farmers have a higher incidence of multiple myeloma, and there is suggestive evidence of an elevated prevalence of its precursor, monoclonal gammopathy of undetermined significance (MGUS), relative to the general population. Pesticide exposures are suspected to play a role; however, the biologic plausibility for associations with multiple myeloma remains unclear. OBJECTIVES Our objectives were to examine the prevalence of MGUS and evaluate associations with a wide range of pesticides in a large sample of farmers. METHODS We obtained sera and assessed MGUS among 1,638 male farmers ≥ 50 years of age in the Agricultural Health Study (AHS), a prospective cohort in Iowa and North Carolina. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed to estimate associations with MGUS for recent use (within the 12 months before phlebotomy) and cumulative intensity-weighted lifetime days of use of specific pesticides. RESULTS The age-standardized MGUS prevalence was significantly elevated among AHS farmers (7.7%) compared with demographically similar men in the National Health and Nutrition Examination Survey (2.8%) or Olmsted County, Minnesota (3.8%; p < 0.001 ). Recent use of permethrin was associated with MGUS [recent use vs. no recent use, OR = 1.82 (95% CI: 1.06, 3.13)], especially among those who had also used it in the past [recent and past use vs. never use, OR = 2.49 (95% CI: 1.32, 4.69)]. High intensity-weighted lifetime use of the organochlorine insecticides aldrin and dieldrin was associated with MGUS relative to those who never used either of these pesticides [OR = 2.42 (95% CI: 1.29, 4.54); p trend = 0.006 ]. We also observed a positive association with high lifetime use of petroleum oil/distillates as an herbicide, as well as an inverse association with fonofos use. DISCUSSION This is the largest investigation of MGUS in farmers and the first to identify an association with MGUS for permethrin, a pyrethroid insecticide previously associated with multiple myeloma. Given the continued widespread use of permethrin in various residential and commercial settings, our findings may have important implications for exposed individuals in the general population. https://doi.org/10.1289/EHP6960.

Abstract
Pyrethroid insecticides are commonly used worldwide. The chronic effects of these compounds are of concern given that epidemiological studies have suggested an association with hematological cancer, particularly in children. However, the biological evidence at molecular and cellular levels is limited. A review on the molecular and cellular effects of pyrethroids is helpful to guide the study of the biological plausibility of the association of pyrethroids with hematological cancer. We reviewed studies suggesting that pyrethroids are genotoxic, induce genetic rearrangements, alter gene expression and modify DNA. All of these biological modifications could potentially contribute to the carcinogenic process in hematopoietic cells.

Abstract
Pesticides are commonly used worldwide and almost every human is potentially exposed to these chemicals. Exposure to pesticides such as permethrin and malathion has been associated with hematological malignancies in epidemiological studies. However, biological evidence showing if these chemicals induce genetic aberrations involved in the etiology of leukemia and lymphoma is missing. In our previous work, we have shown that a single high exposure (200 μm, 24 hours) of permethrin and malathion induce damage in genes associated with hematological malignancies in peripheral blood mononuclear cells analyzed by interphase fluorescence in situ hybridization (FISH). In the present study, we assessed by FISH whether exposure to low concentrations (0.1 μm, 72 hours) of permethrin and malathion induce aberrations in KMT2A and IGH genes, which are involved in the etiology of leukemia and lymphoma. Peripheral blood mononuclear cells were exposed to the chemicals, and damage in these genes was assessed on interphases and metaphases. We observed that both chemicals at low concentration induced structural aberrations in KMT2A and IGH genes. A higher level of damage was observed in KMT2A gene with malathion treatment and in IGH gene with permethrin exposure. We also observed numerical aberrations induced by these chemicals. The most frequent aberrations detected on interphase FISH were also observed on metaphases. Our results show that permethrin and malathion induce genetic damage in genes associated with hematological cancer, at concentrations biologically relevant. In addition, damage was observed on dividing cells, which suggests that these cells maintain their proliferation capacity in spite of the genetic damage they possess.

Abstract
Epidemiological studies have associated the exposure to permethrin and malathion with increased risk of leukemia and lymphoma. The aim of this study was to evaluate whether in vitro exposure to permethrin and malathion induces aberrations in genes involved in the etiology of these hematological malignancies. Genetic abnormalities in the IGH, KMT2A (MLL), ETV6 and RUNX1 genes, and aneuploidy induced by the in vitro exposure to permethrin and malathion (200μM, 24h), were analyzed by FISH in peripheral blood mononuclear cells (PBMCs). The gene fusions IGH-BCL2, KMT2A-AFF1 and ETV6-RUNX1 were further analyzed with nested RT-PCR in PBMCs, and in K562 cells exposed to acute and chronic treatments (0.1μM, 24h or every third day for two weeks) of insecticides. FISH analysis revealed that permethrin induces aneuploidy and structural alterations in IGH and KMT2A genes, and malathion induces breaks in KMT2A. RT-PCR detected ETV6-RUNX1 fusion in PBMCs acutely exposed to permethrin. Permethrin also induced ETV6-RUNX1 and IGH-BCL2 fusions in K562 cells, and malathion induced KMT2A-AFF1 and ETV6-RUNX1 fusions. Overall, we identified that both insecticides induce breaks and fusions in the studied genes, and permethrin induces aneuploidy. This study presents evidence of damage in cancer genes caused by these insecticides.

Abstract
CONTEXT Insecticides are used to control pests. Cypermethrin and fenvalerate are widely used pirethroid insecticides in the world. Rosa canina L. (Rosaceae) is used as a traditional medicinal plant against viral infections and disorders of the kidneys and urinary tract due to its high vitamin C level. OBJECTIVE The genotoxic effects of cypermethrin and fenvalerate were examined with the micronucleus (MN) test. Then, we determined the ability of the water (RC(wtr)) and ethanol (RC(eta)) extracts of rosehip (R. canina) to overcome the possible genotoxic effects of the insecticides. MATERIALS AND METHODS Preliminary studies determined that the application concentrations were 20, 30, 40, and 50 ppm for cypermethrin, 25, 50, 75, and 100 ppm for fenvalerate, and 100 ppm for rosehip extracts. DMSO (dimethyl sulphoxide) (1%) and 1 mM EMS (ethyl methanesulfonate) were used as negative and positive control groups, respectively. The application groups belonging to insecticides and plant extracts were added to culture tubes including chromosome B medium and peripheral blood for MN test. RESULTS The MN frequencies were found 0.725 in the negative control group, 2.700 in the positive control groups, 1.275 in the highest application group of cypermethrin, and 1.600 in the highest application group of fenvalerate. The MN frequencies in cypermethrin + RC(wtr), cypermethrin + RC(eta), fenvalerate + RC(wtr), and fenvalerate + RC(eta) application groups were, respectively, determined as 1.000, 1.075, 1.225, and 1.275. CONCLUSION According to the results, cypermethrin and fenvalerate have genotoxic effects, the water and ethanol extracts of rosehip reduced the genotoxicity of the both insecticides.

Abstract
Pyrethroids are known to be neurotoxic. However, their toxic effects including that of allethrin on the male reproductive tract are not elucidated. Adult male rats were treated orally with 25, 50, 100, and 150 mg/kg body weight allethrin every day for 60 days. Lipid peroxidation was increased (p < 0.001) in the caput, cauda, and testes. Nitric oxide production was increased (p < 0.001) in the caput, but unaltered in the cauda and testes. The activities of catalase, glutathione peroxidase, glutathione-S-transferase, and superoxide dismutase were decreased in the caput and cauda where as a decrease was observed in the testis obtained from allethrin treated rats. In the epididymides and testes, damage to tubular architecture, congestion, degeneration of epithelial cell lining, intestinal edema, and presence of dead or degenerating spermatids were observed in a dose dependent manner. The expression profile of genes involved in spermatogenesis (Tgf-beta1), sperm maturation (Spag11e), and sperm function (Defb22) were reduced (p < 0.001) in allethrin rats. The expression of p53 gene was decreased and increased phosphorylation of MAPK (p42/p44) expression was observed the male reproductive tract tissues of allethrin treated rats. Although earlier studies have reported the effects of allethrin inhalation because of the use of mosquito coils and vaporizers, our results for the first time prove that oral exposure to allethrin could affect fertility and may contribute to deregulation of cell cycle in the male reproductive tract.

Abstract
Bifenthrin (BF) is one of the most commonly used pesticides among the synthetic pyrethroids. The effects of BF exposure on the induction of immunotoxicity and oxidative stress were studied both in adolescent and adult male ICR mice. Both the weights of the spleen and thymus decreased significantly in the adolescent mice when they were treated with 20 mg/kg BF for 3 weeks. We found that the 3-week oral administration of BF during puberty increased the transcriptional levels of the genes TNF and IL2 in the spleen and IL2 as well as IL4 in the thymus. The effect of BF exposure on the induction of oxidative stress was also studied in serum and liver samples. The total antioxidant capacity and activity of superoxide dismutase were altered significantly in the serum of the 20 mg/kg BF-treated adolescent mice, and the activity of glutathione peroxidase (GPX) decreased significantly in the serum of adolescent and adult mice after 3 weeks of oral administration of 20 mg/kg BF. Compared to serum, hepatic GSH content increased significantly in both the adolescent and adult mice exposed to 20 mg/kg BF; hepatic CAT and GPX activities were altered significantly, even in adolescent mice, after treatment with 10 mg/kg BF. Taken together, the results of this study suggest that exposure to BF, especially during puberty, has the potential to induce immunotoxicity accompanied by oxidative stress in male mice. These findings will help in elucidating the mechanism of toxicity induced by BF in mice.

Abstract
In the present study, the effect of methidathion, cypermethrin, and deltamethrin pesticides on Lake Van fish (Chalcalburnus tarichii Pallas, 1811) liver 6-phosphogluconate dehydrogenase enzyme activity was investigated due to the fact that these pesticides are extensively used to improve agricultural productivity in the Van region. 2',5'-ADP Sepharose 4B affinity chromatography was used to purify 6-phosphogluconate dehydrogenase enzyme from fish liver and SDS-PAGE technique was used to control the purity of this enzyme. The in vitro effect of methidathion, cypermethrin, and deltamethrin pesticides on the enzyme activity was investigated. The enzyme was purified 1,050-fold with specific activity of 27.04 EU/mg protein. Moreover, Ki constants of methidathion, cypermethrin, and deltamethrin were to be 3.294 ± 0.215, 0.718 ± 0.095, and 0.084 ± 0.009 mM respectively. The IC50 value were estimated as 9.95 × 10(-5) ± 0.1844 × 10(-5) mM for methidathion, 1.01 × 10(-4) ± 0.01413 × 10(-4) mM for cypermethrin, and 4.43 × 10(-6) ± 0.05653 × 10(-6) mM for deltamethrin. In conclusion, deltamethrin inhibits the enzyme activity more than methidathion and cypermethrin.

Abstract
The binding of permethrin (PE) with calf thymus DNA (ctDNA) in physiological buffer (pH 7.4) was investigated by ultraviolet-visible (UV-vis) absorption, fluorescence, circular dichroism (CD), and Fourier transform infrared (FT-IR) spectroscopy merging with multivariate curve resolution-alternating least-squares (MCR-ALS) chemometrics approach. The MCR-ALS was applied to resolve the combined spectroscopic data matrix, which was obtained by UV-vis and fluorescence methods. The concentration profiles of PE, ctDNA, and PE-ctDNA complex and their pure spectra were then successfully obtained. The PE molecular was found to be able to intercalate into the base pairs of ctDNA as evidenced by decreases in resonance light-scattering signal and iodide-quenching effect and increase in ctDNA viscosity. The results of FT-IR spectra indicated that PE was prone to bind to G-C base pairs of ctDNA, and the molecular docking studies were used to validate and clarify the specific binding. The observed changes in CD signals revealed that the DNA turned into a more highly wound form of B-conformation. The calculated thermodynamic parameters, enthalpy change (ΔH°) and entropy change (ΔS°), suggested that hydrogen bonds and van der Waals forces played a predominant role in the binding of PE to ctDNA.

Abstract
The present study aimed to investigate the genotoxic, cytotoxic and aneugenic effects of 1, 2, 3.75, 7.5, 15, 30 μM concentrations of the insecticides λ-cyhalothrin (LCT) and α-cypermethrin (CYP) on human peripheral blood lymphocyte culture using micronucleus (MN) and fluorescence in situ hybridisation (FISH) methods. All the concentrations were tested to assess the MN and apoptosis effects, and 1 and 2 μM LCT and 7.5 and 15 μM CYP concentrations were tested for FISH analysis. The cytotoxic effect was also observed using trypan blue and the acridine orange/ethidium bromide fluorescence staining method to measure the apoptotic effect. It was observed that both of the insecticides had a cytotoxic effect at all the concentrations (p ≤ 0.001) and apoptotic effect for LCT at 15-30 μM (p ≤ 0.05; p ≤ 0.01) for CYP between 2 and 30 μM concentrations (p ≤ 0.05; p ≤ 0.01). The micronuclei that developed after exposure were induced because of an aneugenic effect (p ≤ 0.001). LCT and CYP might be spindle poisons or caused damaged to centromere/kinetochore function.

Abstract
In this study, 70 Wistar rats were randomly divided into seven equal groups (six experimental and one control), which consisted of animals belonging to both sexes. Different combinations of insecticides were administered daily to the experimental groups (group 1: cypermethrin + piperonyl butoxide (PBO); group 2: alphacypermethrin + PBO; group 3: deltamethrin + PBO; group 4: cypermethrin + PBO + tetramethrin; group 5: alphacypermethrin + PBO + tetramethrin; and group 6: deltamethrin + PBO + tetramethrin) for 28 days. During the study period, mortality and serious clinical findings were not observed in any animal. However, feed consumptions decreased in groups 1 and 3 ( p < 0.05). Red blood cells, white blood cells, and hemoglobin levels, especially in cypermethrin and alphacypermethrin groups (groups 1, 2, and 4), were found to be higher than the control group ( p < 0.05). Furthermore, biochemical changes related to liver, kidney functions, and protein metabolism occurred in males of almost all the groups. Relative liver and kidney weights of the male animals increased in the cypermethrin and alphacypermethrin groups ( p < 0.05). The most common finding observed during the histopathological examination of all the experimental groups was centrilobular degeneration in the liver. It was concluded that although clinical symptoms were not observed, synthetic pyrethroid, synergist, and knockdown agent combinations might cause serious abnormalities when administered in certain doses in mammalians.

Abstract
Permethrin is a common synthetic chemical, widely used as an insecticide in agriculture and other domestic applications. The previous reports indicated that permethrin is a highly toxic synthetic pyrethroid pesticide to human and environmental health. Therefore, the present experiment was undertaken to determine the effectiveness of olive leaf extract in modulating the permethrin induced genotoxic and oxidative damage in rats. The animals used were broadly divided into four (A, B, C and D) experimental groups. Group A rats served as control animals and received distilled water intraperitoneally (n = 5). Groups B and C rats received intraperitoneal injections of permethrin (60 mg kg(-1) b.w) and olive leaf extract (500 mg kg(-1) b.w), respectively. Group D rats received permethrin (60 mg kg(-1) b.w) plus olive leaf extract (500 mg kg(-1) b.w). Rats were orally administered their respective feed daily for 21 days. At the end of the experiment rats were anesthetized and serum and bone marrow cell samples were obtained. Genotoxic damage was assessed by micronucleus and chromosomal aberration assays. Total antioxidant capacity and total oxidant status were also measured in serum samples to assess oxidative status. Treatment of Group B with permethrin resulted in genotoxic damage and increased total oxidant status levels. Permethrin treatment also significantly decreased (P < 0.05) total antioxidant capacity level when compared to Group A rats. Group C rats showed significant increases (P < 0.05) in total antioxidant capacity level and no alterations in cytogenetic parameters. Moreover, simultaneous treatments with olive leaf extract significantly modulated the toxic effects of permethrin in Group D rats. It can be concluded that olive leaf extract has beneficial influences and could be able to antagonize permethrin toxicity. As a result, this investigation clearly revealed the protective role of olive leaf extract against the genetic and oxidative damage by permethrin in vivo for the first time.

Abstract
Cypermethrin (CYP) is one of the most common contaminants in the ecosystem. The effects of CYP exposure on the induction of oxidative stress and endocrine disruption were studied in adolescent male ICR mice. The hepatic activities of antioxidant enzymes including superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT) and total antioxidant capacity (T-AOC) increased significantly after 3 weeks (postnatal day 21-42) of oral administration of 20 mg kg(-1) CYP. In accordance with the enzyme activities, the mRNA levels for the genes encoding these antioxidant proteins, such as Sod1, Sod2, Gpx1 and Gpx2, were also up-regulated significantly in the 10 and 20 mg kg(-1) CYP treatment groups. Furthermore, we also found that the 3-week oral administration of CYP decreased transcription levels of key genes in pathways of cholesterol synthesis and transport and testosterone synthesis including HMG-CoA synthase, steroidogenic acute regulatory protein (StAR) and cytochrome P450 17α-hydroxysteroid dehydrogenase (P450 17α in the liver and testes. Serum testosterone levels also decreased significantly in mice after treatment with 20 mg kg(-1) CYP. Taken together, the results indicated that CYP can induce endocrine disruption in adolescent mice. The findings will be helpful in elucidating the mechanism of toxicity induced by CYP in adolescent mice.

Abstract
Public health agencies utilize aerial insecticides to interrupt an active West Nile virus (WNV) transmission cycle, which may expose WNV-infected birds to these agents. Although resmethrin has been considered benign to birds, no studies have evaluated whether the environmentally employed form of resmethrin with PBO synergist (synergized resmethrin (SR)) can suppress avian immunity to WNV infection and enhance a bird's host competence. Recognizing that wild birds confront toxicological stressors in the context of various physiological states, we exposed four groups (n=9-11) of 9-week-old chickens (Gallus domesticus) to drinking water with either SR (three alternate days at 50 microg/l resmethrin+150 microg/l piperonyl butoxide), CORT (10 days at 20mg/l to induce subacute stress), the combination of SR and CORT, or 0.10% ethanol vehicle coincident with WNV infection. Compared to controls, SR treatment did not magnify but extended viremia by 1 day, and depressed IgG; CORT treatment elevated (mean, 4.26 log(10)PFU/ml) and extended viremia by 2 days, enhanced IgM and IgG, and increased oral virus. The combination of SR and CORT increased the number of chickens that shed oral virus compared to those treated with CORT alone. None of the chickens developed a readily infectious viremia to mosquitoes (none >or=5 log(10)PFU/ml), but viremia in a CORT-exposed chicken was up to 4.95 log(10)PFU/ml. Given that SR is utilized during WNV outbreaks, continued work toward a complete risk assessment of the potential immunotoxic effects of SR is warranted. This would include parameterization of SR exposures with immunological consequences in wild birds using both replicating (in the laboratory) and non-replicating (in the field) antigens. As a start, this study indicates that SR can alter some immunological parameters, but with limited consequences to primary WNV infection outcome, and that elevated CORT mildly enhances SRs immunotoxicity in chickens.

Abstract
Polymorphonuclear neutrophils are professional phagocytes whose efficacy depends on a multicomponent NADPH oxidase for generating superoxide anions and bacterial killing. They can be primed and activated by different agents that can impair oxidative burst and phagocytosis with opposite effects: reduced capability to destroy bacteria or hyperactivation that induces the generation of large quantities of toxic reactive oxygen species, which can damage surrounding tissue and participate in inflammation. The present study was designed to evaluate the effect of sub-chronic (60 days) permethrin treatment (1/10 DL(50)) on rat polymorphonuclear neutrophils respiratory burst. The results show that permethrin treatment increases superoxide anion production (33 times) and the activity of hydrogen peroxide-myeloperoxidase system (67 times). In vitro experiments suggest that this effect can be related to permethrin priming and to physico-chemical changes at the plasma membrane level of neutrophils. The antioxidant supplementation with Vitamin E and coenzyme Q(10) can protect against the abnormal respiratory burst in rat treated with permethrin. The in vitro studies show that neutrophil apoptosis begins soon after 1h of incubation with permethrin (0.725% of total cells) or its metabolites (3-phenoxybenzyl alcohol, 3-phenoxybenzaldehyde and 3-phenoxybenzoic acid 1.36, 2.26 and 1.3 of total cells, respectively) and that the level of apoptotic cells is very low. In conclusion, immunotoxicity of permethrin measured in rats could prompt future studies on the consequences of chronic insecticide exposure.

Abstract
alpha-Cypermethrin, a highly active pyrethroid insecticide, is effective against a wide range of insects encountered in agriculture and animal husbandry. The potential genotoxicity of a commercial formulation of alpha-cypermethrin (Fastac 100 EC, containing 10% alpha-cypermethrin as the active ingredient) on human peripheral lymphocytes was examined in vitro by sister chromatid exchange (SCE), chromosomal aberrations (CAs), and micronucleus (MN) tests. The human lymphocytes were treated with 5, 10, 15, and 20 microg/ml of alpha-cypermethrin for 24- and 48-hr. alpha-Cypermethrin induced SCEs and CAs significantly at all concentrations and treatment times and MN formation was significantly induced at 5 and 10 microg/ml of alpha-cypermethrin when compared with both the control and solvent control. Binuclear cells could not be detected sufficiently in the highest two concentration of alpha-cypermethrin (15 and 20 microg/ml) for both the 24- and 48-hr treatment times. alpha-Cypermethrin decreased the proliferation index (PI) at three high concentrations (10, 15, and 20 microg/ml) for both treatment periods as compared with the control groups. In addition, alpha-cypermethrin reduced both the mitotic index (MI) and nuclear division index (NDI) significantly at all concentrations for two treatment periods. The PI and MI were reduced by alpha-cypermethrin in a concentration-dependent manner during both treatment times. In general, alpha-cypermethrin showed higher cytotoxic and cytostatic effects than positive control (MMC) at the two highest concentrations for the 24- and 48-hr treatment periods. The present study is the first to report the genotoxic and cytotoxic effects of commercial formulation of alpha-cypermethrin in peripheral blood lymphocytes.

Abstract
Carboxylesterases hydrolyze a large array of endogenous and exogenous ester-containing compounds, including pyrethroid insecticides. Herein, we report the specific activities and kinetic parameters of human carboxylesterase (hCE)-1 and hCE-2 using authentic pyrethroids and pyrethroid-like, fluorescent surrogates. Both hCE-1 and hCE-2 hydrolyzed type I and II pyrethroids with strong stereoselectivity. For example, the trans-isomers of permethrin and cypermethrin were hydrolyzed much faster than corresponding cis-counterparts by both enzymes. Kinetic values of hCE-1 and hCE-2 were determined using cypermethrin and 11 stereoisomers of the pyrethroid-like, fluorescent surrogates. K(m) values for the authentic pyrethroids and fluorescent surrogates were in general lower than those for other ester-containing substrates of hCEs. The pyrethroid-like, fluorescent surrogates were hydrolyzed at rates similar to the authentic pyrethroids by both enzymes, suggesting the potential of these compounds as tools for high throughput screening of esterases that hydrolyze pyrethroids.

Abstract
We have investigated the genotoxicity of lambda-cyhalothrin (LCT) (CAS registry No. 91465-08-06), a pyrethroid insecticide, in bone marrow cells and in colonic crypt epithelial cells of groups of four rats per dose treated in vivo by gavage at doses of 0.8, 3.06 and 6.12 mg/kg body weight (body wt). We measured genotoxicity using the micronucleus (MN) assay, scoring 2000 polychromatic erythrocytes (PCEs) per animal for bone marrow and 1000 colonic crypt epithelial cells per animal for the colon. We assessed cytotoxicity in bone marrow by calculating the ratio of PCEs to normochromatic erythrocytes, and in the colonic crypt epithelium by observing the frequency of binucleate cells and the mitotic index in 1000 cells. Apoptosis in colonic crypt epithelial cells was measured by observing the frequency of karyorrhexis and karyolysis in 1000 cells. We found that LCT induced a statistically significant dose-related increase in MN formation in the bone marrow and the colonic crypt. The colonic epithelium was more sensitive to the clastogenic effects of LCT than the bone marrow as judged by the significantly higher frequencies of MN in the colon than in the bone marrow at doses of 3.06 and 6.12 mg/kg body wt.

Abstract
Because of the widespread use of pesticides for domestic and industrial applications the evaluation of their genotoxic effects is of major concern to public health. Although various experimental data have provided evidence that pesticides can possess genotoxic properties in animals and in in vitro test systems after acute and chronic exposure, the information on the genotoxic effects of some of pesticides is limited and inconsistent. In the present study, the genotoxic potential of commonly used pesticides (i.e., dimethoate and methyl parathion from the organophosphate class, propoxur and pirimicarb from carbamates, and cypermethrin and permethrin from pyrethroids) have been evaluated. The genotoxic effects of these substances were examined using the single cell gel electrophoresis (comet) assay in freshly isolated human peripheral lymphocytes. The cells were incubated with 10, 50, 100 and 200 microg/ml concentrations of the test substances for 0.5 h at 37 degrees C and DNA damage was compared with that obtained in lymphocytes from the same donor not treated with substances. Hydrogen peroxide, 100 microM, was used as a positive control. Within the concentration ranges studied, no significant cytotoxic effects were observed. Dimethoate and methyl parathion at 100 and 200 microg/ml; propoxur at 50, 100 and 200 microg/ml, and pirimicarb, cypermethrin and permethrin at 200 microg/ml significantly increased DNA damage in human lymphocytes.

Abstract
In the present study, the effects of subchronic per os exposures to cadmium chloride (CdCl(2)), and a carbamate insecticide, propoxur (Pr), were investigated in male Wistar rats on general toxicological (body weight gain, relative organ weights) haematological (RBC, WBC, Ht, MCV, cell content of the femoral bone marrow) immune function (plaque forming cell (PFC) assay, delayed type hypersensitivity (DTH) reaction) and neurotoxicological (spontaneous and stimulus-evoked cortical activity, nerve conduction velocity) parameters. The animals were treated for 4, 8 and 12 weeks with 6.43 mg/kg CdCl(2), 8.51 mg/kg Pr, or with a combination of 6.43 mg/kg CdCl(2)+0.851 mg/kg Pr or 8.51 mg/kg Pr+1.61 mg/kg CdCl(2). Cadmium exposure affected the relative thymus, liver, and adrenal weight, RBC count, haematocrit and MCV, and there was an increase in nerve conduction velocity and a decrease in the cortical evoked potential latency. Pr induced a decrease in thymus weight, had some effect on the liver weight but none on the electrophysiological parameters. A significant interaction between Cd and Pr was detected by the following parameters: RBC, Ht, PFC, and nerve conduction velocity. The results indicate that combined exposures in humans may result in a shift in the apparent detection limits and/or in the LOEL of the single substances. The latter raises the necessity to reconsider exposure limits in situations where the risk of combined exposure is high.

Abstract
The effects of the combined exposure of cypermethrin (CY), NaAsO2 (As), and HgCl2 (Hg) were investigated in male Wistar rats following 4 weeks of oral exposure. Standard toxicological (body weight gain, organ weights of brain, thymus, heart, lung, liver, kidneys, adrenals, testes, and popliteal lymph node), haematological (white blood cell, red blood cell, haematocrit, MCV-mean volume of red blood cells, and cell content of the femoral bone marrow), and immune function (IgM-PFC response, delayed type hypersensitivity (DTH) reaction) parameters were measured. The two doses selected for the combination were: a high (H) dose equal to lowest observed effect level determined in preliminary experiments (CY(H)=55.4 mg/kg, As(H)=13.3 mg/kg, Hg(H)=3.20 mg/kg), and a low (L) dose which was ineffective (non-observed effect level); CY(L)=11.1 mg/kg, As(L)=3.33 mg/kg, Hg(L)=0.40 mg/kg). CY(H) was combined with As(L) or Hg(L), and the H doses of the heavy metals were combined with CY(L). Beside vehicle control, the H dose components of the combinations were also used as internal controls. The main finding of this study was that certain combinations, when compared to H dose internal control, significantly altered the body weight gain (As(H)+CY(L)), the relative weight of adrenals and popliteal lymph node (CY(H)+As(L) and CY(H)+Hg(L)), the cell content of the femoral bone marrow (CY(H)+Hg(L)), and the time course of DTH reaction (CY(H)+As(L)). According to the present results, combined exposure with CY and the heavy metals investigated can modify the toxicity and/or the functional detection limit of the single substances.

Abstract
Effects of combined exposure with dimethoate (DM), HgCl2 (Hg), and NaAsO2 (As) were investigated following a 28 - day oral exposure in male Wistar rats. In preliminary experiments, the LOEL (Lowest Observed Effect Level) and NOEL (Non Observed Effect Level) doses of the substances were determined using the same experimental system [determination of body weight gain, organ weights of brain, thymus, heart, lung, kidneys, adrenals, spleen, testicles, popliteal lymph node, white blood cell (WBC) and red blood cell (RBC) count, haematocrit (Ht), mean cell volume (MCV) of RBCs, cell content of the femoral bone marrow, IgM-plaque forming cell (PFC) content of the spleen, delayed type hypersensitivity (DTH) reaction] and animal strain. In the combination studies, LOEL dose of DM (28.2 mg/kg) was combined with NOEL doses of the heavy metals ( HgCl2 = 0.40 mg/kg, NaAsO2 = 3.33 mg/kg), and vice versa (DM = 7.04 mg/kg, HgCl2 = 3.20 mg/kg, NaAsO2 = 13.3 mg/kg). In the DM-Hg combinations, significant alterations were found versus the corresponding high- dose internal control in the body weight gain, relative liver and kidney weights, and in the PFC response. When DM was combined with As, interactions were indicated by changes of relative liver weight, MCV value, and the PFC content of the spleen. These results support the theory that the interactions between pesticides and heavy metals may modify the toxic effects of the single substances, and may also change the functional detection limits of the exposure. The changes in the functional detection limits, if they occur, can lead to false-positive and false-negative results in human epidemiological studies.

Abstract
Effects of combined 28 days of oral exposure to the insecticide Permethrin (Pe), alone or in combination with arsenic-III (As) or Hg-II (Hg), were investigated on certain toxicological (body weight, organ weights), haematological (white blood cell (WBC) and red blood cell (RBC) counts, haematocrit (Ht), mean cell volume (MCV), cell content of the femoral bone marrow) and immune function (IgM-PFC, delayed-type hypersensitivity (DTH) reaction) parameters of male Wistar rats. Immunotoxic (H = high) and NOEL (L = low) doses of the three substances were determined in preliminary experiments under identical experimental conditions. In the present study, the immunotoxic dose of Pe (126 mg/kg) was combined with the NOEL dose of As (3.33 mg/kg) or Hg (0.40 mg/kg), and the NOEL dose of Pe (12.6 mg/kg) with the immunotoxic dose of As (13.3 mg/kg) or Hg (3.20 mg/kg). A separate group of animals, treated with the appropriate high dose component only, was used as internal control. Significant interactions were observed in the liver weight of the animals treated with Pe(H)-As(L) or As(H)-Pe(L), in the cell content of the femoral bone marrow in case of Pe(H)-As(L) and Pe(H)-Hg(L) combinations, as well as in the number of PFCs formed from 10(6) spleen cells in the Pe(H)-As(L) and in the maximum of DTH reaction in the Hg(H)-Pe(L) combination. The results show that combined exposures by the investigated substances modify the toxic (including immunotoxic) effects of the single compounds. These findings rise the probability that the interactions observed can also be present in human situations altering the health hazard of this three chemicals.
