The aim of this study was to investigate the dose-related effects of fenitrothion (FNT) on the liver and kidney. The study was conducted on 8-week-old male Wistar rats that were divided into four groups (three experimental groups and one control group) and were treated orally with different doses (25, 50, 100 mg/kg) of FNT for 28 consecutive days. After treatment, the rats were anesthetized with ether and liver and kidney samples were taken for histological studies. The results showed that the histopathological changes in the liver were mainly represented by parenchymatous degeneration of hepatocytes with mild necrosis, leukocytic infiltration in the portal area, severe congestion, and hemorrhage. These changes were dose dependent. Marked tubular dilation, hydropic degeneration in tubular epithelium, moderate congestion, and hemorrhage in the cortical and medulla part of the kidney were recorded. Histopathologic examination of the liver and kidney indicated a significant injury only in rats receiving 100 mg/kg FNT.

The present study was carried out to investigate the effect of arsenic trioxide on the DNA and histomorphology of testis, liver and kidney of Swiss albino mice, Mus musculus. Oral administration of arsenic trioxide induced DNA damage in the testis, liver and kidney marked by light pink staining of nuclei after Feulgen’s reaction with reduced fine chromatin. Simultaneously severe histological changes were noted like distortion of seminiferous tubules, disorganization of spermatogonia, spermatocytes and spermatids with cytoplasmic vacuolization and nuclear pycnosis in testis. There was almost disappearance of sinusoids due to disruption of hepatic plates, inflammatory cellular infiltration around central veins and cytoplasmic vacuolization in hepatocytes with large irregular nuclei in liver of treated mice. Disorganized glomeruli with distorted Bowman’s capsules and mild to severe multifocal cloudy and hydropic degeneration with necrosis of tubules were observed in the kidney of treated mice. Inference drawn from the study indicated that arsenic induced both genotoxic histotoxic lesions.

Abstract Considering that the involvement of reactive oxygen species (ROS) has been implicated in the toxicity of various pesticides, this study was designed to study the ameliorative effect of Vitamin E (100 mg/kg body weight) on mice (25 - 30 mg) treated with diazinon (32.5 or 16.25 mg/kg body weight) organophosphate insecticide for 14 days. Subchronic DZN exposure and the protective effects of vitamins E (vitE) were evaluated for their effects on haematological indices, the enzymes concerning liver damage [plasma alanine aminotransferase (ALT), aspartate aminotaransferase (AST), alkaline phosphatise (AIP), and some parameters of kidney function (urea and creatinine) in mice. Additionally, the histopathological changes in liver and kidney tissue were examined. The high dose of diazinon (DZNH) decreased the body weight significantly at the end of experiment. Additionally, the liver and kidney were examines for histopathological changes. The high dose of diazinon decreased body weight significantly. Moreover, there was a statistically significant decrease in haemoglobin (Hb), red blood cell (RBC) and hematocrit (Hct) in diazinon-treated mice compared to controls. This decrease was partially remedied in the diazinon-treated group that also received vitE. Damage in the liver and kidney tissues was also evident as elevated plasma ALT, AST, ALP, urea and creatinine. VitE partially counteracts the toxic effect of DZN and repairs tissue damage in the liver and kidney, especially when supplemented to 1/4 LD50 intoxicated animals. Histopathological changes in liver and kidney were observed only in 32.5 mg/kg DZN given group. These results suggest that the effects of DZN are dose dependent. No pathological findings were observed in vitE + DZN treated groups. According to the present study, we conclude that vitE can reduce the detrimental impacts of diazinon on haematological indicies, as well as liver and kidney function.

  Objective: Tamarind (Tamarindus indica) has been used as a medical plant for treating many human and animal diseases and widely used as a traditional herbal medicine for the treatment of snake bites. The objective of the study is to investigate whether tamarind seed extract (TSE) has neutralization activity on an adverse histological reaction against venoms of the King Cobra.Methods: A total of 20 healthy mature male mice were randomly divided into 4 groups with 5 mice in each. The control group was injected with 1 ml of normal saline. The second group was injected subcutaneously with a single dose of 24.96 μg/20 g King Cobra venom (KCV) solution. The third group was injected with the same dose of KCV solution and 10 mg/20 g of TSE. The fourth group was injected with the same dose of KCV solution and 15 mg/20 g TSE solution. The animals were sacrificed after 24 hrs of injection of the solution. Fragments of muscle, kidney, and liver were fixed in 10% neutral buffered formalin and processed for light microscopical studies.Results: The result showed that TSE reduced the histopathological changes induced by the KCV in the muscles, livers, and kidneys, and the improvement was proportional to the applied dose of the TSE indicating that TSE prevents adverse histological changes in the muscle, liver, and kidney.Conclusion: The present study demonstrated that TSE reduced the histopathological changes in the muscle, liver, and kidney induced by KCV in mice.

Abstract The effect of naringenin, a flavonoid found in grapefruit, orange, and tomato, on lipid peroxidation and histopathological changes in the liver and kidneys of alloxan-induced diabetic mice were investigated. Two days after alloxan injection (75 mg kg−1, i.v.), naringenin ethanolic solution (0.5 % v/v) was given to mice intraperitoneally (50 mg kg−1 per day) for seven days. Naringenin’s impact on lipid peroxidation was measured by the 2-thiobarbituric acid test and histopathological changes were examined under a light microscope. Naringenin administration resulted in a significant decrease of lipid peroxidation level in liver and kidney tissue, as well as in a decreased number of vacuolated liver cells and degree of vacuolisation. Indications of tissue repair in kidney suggested that amelioration of diabetes-induced renal damage could be achieved over a longer period of time. Findings suggest that naringenin could be considered a dietary supplement in the prevention or treatment of diabetic complications and other diseases connected with oxidative stress, and gives a hope that it could show similar effects in the treatment of diabetes in humans.

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

This study was conducted to compare between two types of opportunistic fungi (Aspergillus fumigatus and Penicillium chrysogenum) in concerning their pathogenicity after intraperitoneal inoculation of mice. A total of twenty four male albino mice were used in this study which divided equally into 3 groups, The first and second groups were inoculated with 0.2ml of 1x 107spores/ml of A. fumigatus and P. chrysogenum  intraperitonially respectively, while the third group was inoculated with normal saline which served as control group. All animals were monitored for 2 weeks after infection. The blood samples were collected by heart puncture after 18 days post infection to isolate of serum that used for biochemical analysis of liver and kidney functions. After that, all animals were sacrificed. Some internal organs of infected groups (liver, kidney, intestine, heart, spleen and lung) were taken to study the histopathological changes. It was found that there was severe histopathological changes in studied organs of infected mice particularly liver, kidney, spleen and intestine which corresponding with significant variation (p<0.01) in enzyme activities of liver and kidney like (Alanine Aminotransferase (ALT), Urea and Creatinine). Also, It was found that P. chrysogenum had more impact on these enzymes (15.65 ± 0.78, 135.23 ± 8.75 and 0.928 ± 0.02 respectively) than A. fumigatus (21.70 ± 1.04, 57.91 ± 5.99 and 0.587 ± 0.03 respectively). Therefore, the present study indicated that fungi present in the environment can induce severe inflammation reach to tissue damage in most vital internal organs So, further studies should be performed to determine the specific virulence factors and active components, which are responsible for pathogenesis of A. fumigatus and P. chrysogenum in spite of the fact that P. chrysogenum can produce antibiotic.
