AbstractCypermethrin (CYP) is one of the most common active ingredients in most insecticides, mosquito coils and powder used in Nigeria. dichlorvos (DDVP) is the most indiscriminately used fumigant in most rural and sub-urban areas in Nigeria. These fumigants can easily be accessed without proper method of usage thus exposing the population to their toxic effects. As a result, this study was initiated to determine the effects of sub-acute exposure of CYP and DDVP on some biochemical and histopathological parameters of albino rats. In this study, forty (40) albino rats of 10 groups of 4 rats per group, with one group serving as control, were exposed to these fumigants in a poorly ventilated area for 4hours per day over 2, 4 and 6 weeks. The results showed observable changes in liver enzyme activities (p<0.05) in groups exposed to DDVP for 2, 4 and 6 weeks. The groups exposed to CYP showed mild changes in liver enzyme activities when compared with the DDVP groups. Increase in activity of the liver enzymes was also observed in the groups exposed to a mixture of DDVP+CYP for 2, 4 and 6 weeks. The urea, creatinine and electrolytes levels in all the groups exposed to DDVP, CYP and DDVP+CYP for 2, 4 and 6weeks were significantly (p<0.05) increased. Also WBC and platelets in all the groups exposed to DDVP and CYP recorded significant changes. The histology report of the lungs and liver showed moderate lymphocytic infiltration and hepatocytic steatosis which progressed with duration of exposure to the fumigants, while the kidneys showed no remarkable changes. The results of this study suggest that DDVP and CYP have relative toxic effects in the exposed animals and should be used with caution to avoid human exposure to their visible toxicities.

Background and objective: Patients on blood transfusion may develop complications related to iron overload and the effects of chelating agents (drugs), which adversely affect the liver in thalassemia, which is a genetic blood disorder of hemoglobin synthesis that causes severe anemia. This study aimed to assess the effect of deferasirox and deferoxamine drugs on liver enzyme activities (aspartate transaminase, alanine transaminase, and alkaline phosphatase), and serum ferritin level in β_thalassemic patients. Methods: This study was carried out in Erbil city from October 2017 to February 2018. Blood specimens were collected in Hawler thalassemia center and Raparin hospital. The samples included 105 individuals; 70 β-thalassemic patients (35 treated by deferasirox as group A and 35 treated by deferoxamine as group B), and 35 healthy individuals (control group C). Results: The serum aspartate transaminase and alkaline phosphatase activities in β-thalassemic patients were higher than that of controls. The serum alanine transaminase activity in the patients' groups showed non-significant elevation than that of controls. The serum ferritin level in the patients was significantly higher than that of controls. Conclusion: Our finding showed that both deferasirox and deferoxamine drugs affect liver enzymes and increase ferritin level.

Acute And Chronic Effects

Deoxynivalenol (DON) is a frequent contaminant of feeds in aquaculture, but the consequences of this contamination have rarely been evaluated. Previous studies on carp indicated effects of DON on liver function and histology after four weeks of feeding. The present study aimed to unravel the time course of liver responses of carp to orally applied DON. Therefore, liver enzyme activities and histology have been investigated after 7, 14, 26 and 56 days of DON feeding. The acute response comprises down-regulation of biotransformation enzymes, whereas the chronic response to DON is characterised by activation of alanine aminotransferase which indicates damage to liver tissue. Examination of histological sections of liver tissue revealed that changes such as fat aggregation, vacuolisation and hyperaemia were present after 14 and 26 days of exposure to DON but not thereafter. Several enzymes involved in glutathione cycling and reduction of oxidative stress were found to be reduced after 26 and 56 days of DON feeding. The results suggest that supporting the antioxidative system, e.g. by using glutathione-enriched yeast extracts as a food additive, might be successful in preventing the effects of DON in carp. This is the basis of a fundamental hypothesis since DON contamination of fish feed leads to pronounced effects on liver histology and liver enzyme activities which may also cause changes in the normal liver metabolism of endogenous and xenobiotic compounds.

Objective: The objective of this study was to determine if there were any harmful effects of monosodium glutamate (MSG) on the liver of Wistar albino rats chronically at three different doses, namely, low, mid, and high doses equivalent to human consumption doses in developing countries. Methods: The Wistar albino rats (n=24) were divided into four groups, namely control, Low dose MSG (180 mg/kg), Mid dose MSG (360 mg/kg), and High dose MSG (720 mg/kg). At the end of the experimental period (120 days), animal blood was collected retro-orbitally to analyze the liver enzymes such as aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), Total protein, Albumin, and Total Bilirubin in blood serum. Lipid profiles, namely, Triglycerides, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and Total cholesterol were subjected to analysis using blood serum. Results: Significant increase (p<0.05) in AST, ALT, ALP, and total bilirubin in serum of MSG induced low, mid, and high dose groups when compared to control group were recorded. There was a significant increase (p<0.05) in LDL, decrease in HDL, increase in total cholesterol and triglycerides of MSG-induced animal groups. Conclusion: The effects of MSG on serum liver enzymes and lipid profiles in this present animal study were not severely alarming even though the dosage was chronic which opens further discussion on the controversies revolving around MSG.

Chlorpyrifos (CPF) is a very toxic pesticide commonly used for controlling agriculturally important pests. The present study investigates DNA damaging effects of CPF on Clarias gariepinus was assessed using genetic assays. Fish were exposed to varying concentrations of CPF (100ppm, 200ppm and 300ppm) at 96 hours (acute exposure). LC50 of the pesticide was found to be 120ppm and one-tenth of the LC50 (12ppm) was taken for the chronic exposure. Distilled water and colchicine were used as negative and positive controls respectively. After 28 days of chronic exposure, fish were fed with inclusion of B. sapida seed (powder) for 14 days. Liver and gills of the fish were removed following 96h exposure, days 7, 14 and 28 of the chronic exposure as well as after the period of amelioration (14 days) for CA assay and histopathological analysis. The results of CA assay showed statistically significant (p ˂ 0.05) increase in CA in a dose-dependent manner for all the exposed groups after acute exposure and time dependent after chronic exposure. Also, this study showed that CPF can potentially induce genotoxic and histopathological changes in fish and other aquatic organisms.
