Biomorphometric and hematobiochemical alterations in the juvenile african catfish Clarias gariepinus exposed to propranolol. BMC ZOOL 2024; 9:11. [PMID: 38902830 PMCID: PMC11188512 DOI: 10.1186/s40850-024-00196-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Accepted: 03/01/2024] [Indexed: 06/22/2024] Open
Abstract
Propranolol (PRO) is a beta-blocker drug used for the treatment of anxiety, chest pain, migraine and tremors. The present study investigated whether sublethal concentrations of PRO have effects on the body condition, biochemistry, and hematology of Clarias gariepinus juveniles. The 96-h median lethal concentration (LC50) of the drug, which was established through an acute toxicity study, was 9.48 mg/L. Based on these values, the fish were exposed for 21 days to the control and sublethal concentrations of 1.90, 0.95, and 0.63 mg/L, which are equivalent to the 1/5th, 1/10th, and 1/20th of the LC50 of PRO, respectively. After 21 days of exposure, the fish were removed from the toxicant and kept in toxicant-free water for 7 days to recover. The standard length and body weight of each fish were measured after each exposure period. The condition factor (CF) and hepatosomatic index (HSI) were not significantly affected by the drug. The red blood cell (RBC) count, hemoglobin (Hb) count and packed cell volume (PCV) decreased from day 7 to 21 at the tested concentrations, while the white blood cell (WBC) count significantly increased. There were alterations in the mean corpuscular volume (MCV), mean corpuscular hemoglobin concentration (MCHC), and mean corpuscular hemoglobin (MCH) in the exposed groups compared to those in the control group. When neutrophil counts increased, the lymphocyte counts decreased, but the monocyte, basophil cell and eosinophil cell counts were not affected. Among the liver enzymes, only aspartate aminotransferase was significantly stimulated in the groups that were exposed to the drug. The protein and glucose levels of fish exposed to the drug decreased. Most of the studied parameters returned to their original values after the 7-day recovery period. The information provided in the current study will be helpful in the monitoring of PRO contamination in aquatic environments.

Abstract
Ivermectin (Ive) has exceedingly efficient against several microorganisms including viruses; therefore, it could help as a potential treatment of COVID-19. Because of increasing consumption of ivermectin and vitamin C (Vit.C) in hope to treat COVID-19, and because of ivermectin nephrotoxic effects have not been fully clarified especially in juvenile age, it was conducted to examine the histopathological and biochemical effects of ivermectin on adult and juvenile kidneys, and to assess the possible protective role of Vit.C against this potential toxicity. Rats were divided to 4 subgroups (Control subgroup, Vit.C subgroup, Ive subgroup, and Vit.C+Ive subgroup), 1 week after 4 doses of ivermectin (0.4 mg/kg Ive±1.25 mg/kg Vit.C), blood samples obtained for assessment of kidney function test, part of kidneys prepared for determination of matrix metalloproteinase-9 and antioxidant enzymes essay. Other parts prepared for histopathological and ultrastructural examination. Results showed that administration of ivermectin led to attenuation in kidney function and in activities of the antioxidant enzymes and increase in matrix metalloproteinase-9 activity. In addition, there were histological damages (shrunken glomeruli, widened urinary space, cytoplasmic vacuolation and pyknotic nuclei with epithelial exfoliation, extravasated blood, and mononuclear cell infiltration) and immunohistochemistry revealed increase in percentage of Bax proapoptotic protein expression. Also, ultrastructure examination showed alteration in cell architecture. All these changes were more obvious in juvenile group while co-administration of Vit.C led to significant protection more in adult group. In conclusion, Ivermectin should be used cautiously especially in juvenile age, and co-administration of Vit.C is highly recommended.

Abstract
Root mutualistic microbes can modulate the production of plant secondary metabolites affecting plant-herbivore interactions. Still, the main mechanisms underlying the impact of root mutualists on herbivore performance remain ambiguous. In particular, little is known about how changes in the plant metabolome induced by root mutualists affect the insect metabolome and post-larval development. By using bioassays with tomato plants (Solanum lycopersicum), we analyzed the impact of the arbuscular mycorrhizal fungus Rhizophagus irregularis and the growth-promoting fungus Trichoderma harzianum on the plant interaction with the specialist insect herbivore Manduca sexta. We found that root colonization by the mutualistic microbes impaired insect development, including metamorphosis. By using untargeted metabolomics, we found that root colonization by the mutualistic microbes altered the secondary metabolism of tomato shoots, leading to enhanced levels of steroidal glycoalkaloids. Untargeted metabolomics further revealed that root colonization by the mutualists affected the metabolome of the herbivore, leading to an enhanced accumulation of steroidal glycoalkaloids and altered patterns of fatty acid amides and carnitine-derived metabolites. Our results indicate that the changes in the shoot metabolome triggered by root mutualistic microbes can cascade up altering the metabolome of the insects feeding on the colonized plants, thus affecting the insect development.

Comp Biochem Physiol C Toxicol Pharmacol 2021; 248:109108. [PMID: 34126252 DOI: 10.1016/j.cbpc.2021.109108] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2021] [Revised: 05/23/2021] [Accepted: 06/06/2021] [Indexed: 11/28/2022]
Abstract
This study was carried out to determine the effect of clotrimazole (CTZ), an imidazole fungicide on behavior, brain acetylcholinesterase, lipid peroxidation and oxidative stress parameters in Clarias gariepinus juveniles. Fish were acutely exposed to five nominal concentrations of CTZ and control to assess the behavioral effects on fish. To determine the effects on brain acetylcholinesterase, lipid peroxidation and oxidative stress parameters, fish were exposed to three sub-lethal concentrations vis 7.76, 3.89 and 1.94 mg/L which corresponds to 20 10 and 5% of 96 h LC50 value of CTZ respectively and a control for 21 days and allowed to recover for 7 days. The brain, liver and gills were sampled weekly. Fish exposed to different concentrations of the drug displayed behavioral responses such as reduced swimming rate, mucus secretion, decrease in both the feeding frequency and rate. A duration dependent increase in the levels of brain acetylcholinesterase was observed among the exposed groups. The result of the sub-lethal exposure revealed concentration and duration significant increase in lipid peroxidation (LPO), catalase activity (CAT), superoxide dismutase (SOD), reduced glutathione (GSH), glutathione reductase (GR) and glutathione peroxide (GPx) in both the liver and gill tissues of the exposed groups compared to the control. The effects of the drug on many of the observed parameters did not wane after the 7-day withdrawal period. This study revealed that CTZ has a negative impact on the observed parameters, thus providing additional evidence of its toxic effect on non-target aquatic species, especially fish.

Abstract
Clotrimazole (CLO) is an imidazole fungicide used in human and veterinary medicine for treating fungal infection. This study evaluated the changes in morphological, haematological and biochemical indices in Clarias gariepinus juveniles exposed to CLO. After the acute exposure, the 96 h LC50 value of CLO determined by probit analysis was 38.79 mgl-1. Based on this value, fish were exposed to sublethal concentrations of 7.76, 3.89, 1.94 and 0.00 mgl-1 (control) of CLO for 21 days and were allowed to recover for 7 days. The result revealed no significant effect on the hepatosomatic index and condition factor of the exposed fish. There were concentration and time-dependent significant decreases in red blood cell (RBC), haemoglobin (Hb), packed cell volume (PCV) and mean corpuscular volume (MCV) with significant increase in the white blood cell (WBC), mean corpuscular haemoglobin concentration (MCHC), and mean corpuscular haemoglobin (MCH) in the exposed group when compared with the control. A mixed trend was observed in the levels of neutrophils, lymphocytes, monocytes and eosinophils. The levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP) and glucose values significantly increased, while protein levels were reduced (p < 0.05) throughout the 21-day exposure and the 7-day recovery period. The present research indicated that CLO may have potential toxic effect on non-target organisms especially fish and, therefore, should be monitored in the aquatic ecosystem.

Abstract
Chlorpromazine (CPZ) is among the most famous drugs used for the treatment of psychosis such as delusions, hallucinations, schizophrenia, paranoia, or disordered thought in humans. In the present study, the acetylcholinesterase (AChE) activity and oxidative stress parameters in the brain of Clarias gariepinus juveniles exposed to CPZ were investigated. Fish were exposed to 0.53, 1.56, and 2.11 mg/L corresponding to 5, 10, and 20% of the 96 h LC50 of CPZ on C. gariepinus, respectively. The fish brain was sampled on days 1, 7, 14, and after 7-days recovery. Our results indicate that AChE values were significantly higher in exposed groups compared to the control on days 7, 14, and 7-days recovery. The values of lipid peroxidation (LPO), glutathione reductase (GR), and glutathione peroxidase (GPx) increased compared to the control while catalase (CAT) and superoxide dismutase (SOD) significantly declined at higher CBZ concentrations. While LPO and CAT returned to the same range as the control values after the 7-day withdrawal from the drug, AChE, SOD, GR, and GPx did not. The use and disposal of CPZ should be strictly regulated to avoid possible ecotoxicological impacts on non-target organisms.

Assessing the toxicity of the benzamide fungicide zoxamide in zebrafish (Danio rerio): Towards an adverse outcome pathway for beta-tubulin inhibitors. ENVIRONMENTAL TOXICOLOGY AND PHARMACOLOGY 2020; 78:103405. [PMID: 32446185 DOI: 10.1016/j.etap.2020.103405] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 04/28/2020] [Accepted: 04/30/2020] [Indexed: 06/11/2023]
Abstract
Commercial benzamide fungicides are applied to crops to control damage caused by oomycete fungi and are used as veterinary pharmaceuticals in aquaculture. The mechanism of action of these fungicides is to induce mitotic arrest via binding to beta-tubulin, thus inhibiting tubulin polymerization. However, there are little toxicity data available for benzimidazole fungicides in fish. To address this knowledge gap, we conducted zebrafish embryo toxicity tests to assess deformities, survival, and sub-lethal responses following exposure to zoxamide (0, 0.5, 1.0, 2.5, 5.0 and 10 μM zoxamide). We hypothesized that skeletal deformities would be prevalent in zebrafish due to its mechanism of inhibiting beta-tubulin polymerization. Zoxamide was relatively toxic to zebrafish embryos and larvae, and survival was reduced ∼50 % at 2 days post fertilization (dpf) with 10 μM exposure and over time at 6 dpf, 2.5 μM exposure reduced survival by ∼20 %. Frequency of hatch was also reduced/delayed in zebrafish at 3 dpf with >2.5 μM zoxamide. Pericardial edema, body length shortening, and spine curvature were observed in larvae exposed to >5 μM. Mitochondrial bioenergetics were assessed in ∼30 hpf embryos (24-hour exposure) using an XFe24 Flux Analyzer and regression analysis revealed a negative relationship between basal respiration and zoxamide concentration. Superoxide dismutase 1 and caspase 3 mRNA levels were both decreased in 6 dpf larvae exposed to 2.5 μM zoxamide, but were not changed in expression at 0.5 nor 1 μM zoxamide. Continuous 6-day exposure to zoxamide reduced larval activity at 2.5 μM; conversely a 24-hour exposure (at 5-6 dpf) induced hyperactivity at 5 μM suggesting dose and time dependent effects on fish behavior. Based on sub-lethal endpoints, we conceptualize an adverse outcome pathway for chemicals that inhibit tubulin polymerization.
