Abstract Abamectin (Avermectin B1a), is a natural fermentation product derived from the soil bacterium Streptomyces avermitilis. Abamectin (Avermectin B1a) is widely used as an insecticide, acaricide, and anthelmintic. The present study assessed the effects of repeated subacute and subchronic exposure to the commercial formulation of abamectin (Vertemic, 1.8% EC) in albino male rats. The toxic effects of abamectin were studied. The various biochemical parameters and histopathological changes were noted. A stomach tube was used to orally administer sublethal doses of abamectin suspended in corn oil to the rats. The animals were divided into four groups. Rats of the group T1 were orally administered a sublethal dose of 30 mg/kg body weight (b.wt.) (1/10 LD50) three times a week for 30 days and the animals in group T2 were exposed to 10 mg/kg b.wt. (1/30 LD50) for 210 days, once a week. Two control groups (C1 and C2) were used in parallel studies, where animals were administered a corn oil vehicle. At the end of the study period, blood samples were collected from all groups to measure plasma alanine aminotransferase (ALT), aspartate aminotransferase (AST) activities, and the levels of creatinine and urea. Also, total protein and RNA contents were determined in the liver and kidney tissues. Changes in biochemical parameters were more intense in male rats from group T2 than those reported in group T1. The levels of ALT, AST, urea and creatinine were significantly elevated in rats from group T2 when compared to the control. In group T2, a significant decrease in the levels of total protein and RNA in both the liver and kidneys was observed. Fertility was also significantly reduced in male rats ingesting abamectin in group T2. The number of offspring was significantly reduced. Histopathological changes were more intense in male rats from group T2 than those from group T1. In conclusion, the results of this study demonstrate that subchronic oral administration of abamectin altered some biochemical parameters which correlated with histopathological changes

Currently, there is a growing interest in medicinal plants, because of an increased demand for alternate therapies. In this study, the antimicrobial activity and toxicity of the essential oil of Lippia origanoides (L. origanoides) were investigated. The essential oil of L. origanoides was extracted by steam-dragging distillation and its constituents were identified by chromatography coupled with mass spectrometry. Among the 15 compounds identified, the most abundant were carvacrol (29.00%), o-cymene (25.57%), and thymol methyl ether (11.50%). The essential oil was studied in antimicrobial assays to determine the MIC and MBC. The results indicated that a concentration of 120μL/mL of oil was sufficient to inhibit the growth of the following microorganisms: Escherichia coli (ATCC 25922), Staphylococcus aureus (ATCC 25923) and Salmonella cholerasuis (ATCC 10708). Acute and chronic toxic effects of orally administered oil were investigated in Wistar rats by using standard methods. Doses of 30, 60 and 120mg/kg of the essential oil did not induce significant changes in weight, behavior or hematological and biochemical parameters in the animals. There were no signs of any histopathological changes to the liver, kidneys or heart of the treated rats, suggesting that Lippia origanoides oil is non-toxic after oral administration in acute or chronic toxicity studies. The results obtained in this study show that the essential oil of L. origanoides has a high safety margin, with no detectable toxic effects in rats treated with doses to 120mg/kg. In addition, L. origanoides oil demonstrated potent antimicrobial activity against S. aureus, E. coli and S. cholerasuis. Based on these findings, this essential oil may have practical application as a veterinary antimicrobial.

Aflatoxin produced by Aspergillus flavus toxigenic strain was selected as a potent and widely distributed hepatotoxin that induces much health and economic hazards in animals and humans. A. flavus was cultivated on rice to produce the aflatoxin used in the present study. It was aimed to study the adverse effects of aflatoxin on some biochemical parameters in serum and liver of ducklings as well as to evaluate the possible protective effects of N.sativa crushed seeds against the adverse effects of this. Total proteins, albumin, globulins, alanine aminotransferase (ALT) (EC 2.6.1.1) and aspartate aminotransferase (AST) (EC 2.6.1.2), cholesterol and triacylglycerols were measured in the serum of the test animal. The levels of hepatic malondialdhyde and glutathione level, glutathione S-transferase (GST) (EC: 2.5.1.18) activity, aflatoxin residues and histopathological changes were also measured. The obtained results suggest that the addition of N. sativa to duckling’s ration has a protective effect against aflatoxicosis. The result concluded that aflatoxin had hepatotoxic effects through decrease of total proteins, albumin, glutathione and glutathione S-transferase. In addition, aflatoxin induced histopathological changes of liver of the test animal and residues of aflatoxin were measured. So, we advice to use N. sativa as a feed additive for controlling aflatoxicosis in poultry farm   DOI: http://dx.doi.org/10.3126/njst.v14i2.10419   Nepal Journal of Science and Technology Vol. 14, No. 2 (2013) 81-90

Objective: This study aims to investigate the hepatotoxicity of metoprolol and find a prophylactic way to protect the liver through the use of Vitamin E. Methods: A total of 18 male rabbits were divided randomly into three groups, with six in each group. Group I (control) received corn oil, Group II was treated with metoprolol (20 mg/kg), and Group III was treated with Vitamin E (175 mg/kg) 30 min before metoprolol treatment. All treatments were given orally and daily for 14 days; animals were sacrificed at day 15. Biochemical parameters were estimated, and the liver was used for histopathological examinations. Results: Histopathological changes of liver injury were found in all metoprolol-treated rabbits, while these changes were minimized in all rabbits who were given Vitamin E. Serum liver function tests and malondialdehyde (MDA) were significantly elevated after metoprolol treatment and returned close to the control value on prior treatment with Vitamin E. Serum MDA, aspartate aminotransferase, and alanine aminotransferase were significantly decreased following treatment with Vitamin E. Conclusion: Vitamin E may have a hepatoprotective effect against metoprolol-induced liver injury in rabbits.

This study aimed to examine the hepatoprotective effects of the superfine particles of Radix Tetrastigma (SPRT) against CCl4-induced acute liver damage in rats. Animals were treated with SPRT (0.3, 0.6, and 1.2 g/kg) and showed remarkable hepatoprotection against CCl4-induced hepatotoxicity. CCl4 altered various biochemical parameters in rat liver, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), malondialdehyde (MDA), superoxide dismutase (SOD), histopathological changes, and Bax and caspase-3 expressions. SPRT significantly prevented increases in ALT and AST levels, reduced MDA level, decreased Bax and caspase-3 protein expression, enhanced SOD activity, and provided significant amelioration in the histopathological lesions. These findings suggested that SPRT has significant protective effect against acute hepatotoxicity induced by CCl4 in rats.
