Aim: To study the comparative effect of Acetaminophen induced liver toxicity with aqueous extract of Azadirachta Indica (Neem) and vitamin E on the basis of liver Histopathology. Methods: Sixty Wistar Rats of both sexes were split into four groups. Each group contained 15 animals. The control group was group A, Group B was treated orally with single dose of Paracetamol 2 mg / kg by weight, Group C was administrated orally with aqueous Neem extract 500 mg/kg +2 mg/Kg by weight oral Paracetamol, and Group D was given orally paracetamol+Neem extract+Vitamin E with 100mg/Kg/body weight for 15 days. Rats from all groups were decapitated, the liver was sliced, and liver tissues were taken for histological examination. Tissue samples were fixed in 10% formaldehyde, embedding in paraffin followed by Hematoxylin and Eosin dye (H&E) and observed under 400x magnification with a digital microscope. Results: On Histopathological examination of the rat`s liver in we found that the control group had a normal appearance, colour, and uniform surface without any necrosis. Group B showed severe necrosis and haemorrhagic patches. In comparison, Group C revealed normal appearance, colour, and smooth surface with no necrotic alterations. Livers from the group D looked virtually normal in terms of colour, undersurfaces, and organ weight. However, hepatoprotective effects were observed in the Group C and D. Therefore, we can conclude that Azadirachta indica and Vitamin E could serve as a good medication for defence against liver injury. Conclusion: Our findings showed thatextract of Azadirachta Indica and Vitamin E exhibited hepatoprotective effects on the Wistar rats that were subjected to Acetaminophen. Key words: Azadirachta Indica leaf extract, Vitamin E, hepatoprotective Paracetamol, Wistar rats.

Background: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures. Purpose: The study was designed to investigate the effect of Corchorus olitorius extracts on the testis of adult Wistar rats. Method: A total number of thirty two adult Wistar rats weighing between 180 and 200 grammes separated into four groups labeled A,B,C and D respectively were used for the study. Animals in group A which served as the control group were fed with the normal rat chow and water only. The group B rats were administered 100mg/kg body weight of aqueous extract of Corchorus olitorus; while those in group C were administered 500mg/kg body weight of the extract. The group D rats received 1000mg/kg body weight of the extract. For a period of four weeks, the different experimental animal groups received the respective aforementioned treatments once daily, around nine- o’clock in the morning through oral intubation. At the end of the 28 day treatment, the animals were sacrificed and the testes harvested for histological, investigation, and through cardiac puncture, blood samples for some hormonal studies was also collected and investigated using standard laboratory standards. Results: Observations made showed that the extract produced no histological distortions, degenerative or defective effects on the testicular tissues. The testosterone levels of group B, C, and D rats were observed to be significantly higher (P<0.005) than that of the group A (control group).ound: The extract of Corchorus olitorius has a reasonable content of vitamins A and C, calcium, iron and fibre, and therefore enjoys a universal application in the treatment of some disease conditions, even as the whole leaf is a very important component of food in so many cultures.

Background: Cadmium is a human carcinogen element and one of the most toxic pollutants in the environment. Present study aims at histomorphological study of some of the effects of Moringa oleifera oil and cashew (Anarcardium occidentale) nuts oil on Cadmium-induced liver damage in wistar rats. Methods: Thirty-five Wistar rats (80-180 g) were randomly selected and divided into seven groups of five rats each after acclimatization for two weeks. Group A which served as control received phosphate buffer, Group B received Cadmium only (3.5 mg/kg body weight). Group C received Vitamin C and Vitamin E; Group D received Vitamin C, Vitamin E and Cadmium. Group E received Cadmium and Moringa oleifera oil, Group F received Cadmium and Cashew nut oil and Group G received Cadmium (3.5 mg/kg body weight) and Moringa oleifera oil and Cashew (Anarcardium occidentale) nut oil. Results: Histological examination revealed normal histo-architecture of the liver, the central vein and the hepatocytes were seen clearly and there was orderly arrangement of the hepatocytes in Group A (control group). In group B, there was enlarged portal vein and there was distorted arrangement of the hepatocytes. In group C, the hepatocytes and the central vein were seen. In group D, the central vein and hepatocytes were seen though not orderly arranged. In groups E, F and G, there was restoration of the hepatocytes and the central vein was seen. Conclusion: This therefore suggests that Moringa oleifera oil and Cashew (Anarcardium occidentale) nut oil have ameliorative effects which led to the restoration of the damaged and distorted hepatocytes.

Abstract: Canola oil is a source of vegetable oils which contains high unsaturated fats that can reduce the risk of coronary heart disease, especially atherosclerosis. One of the trigger factors of atherosclerosis is hypercholesterolemia. This study aimed to evaluate the histopathological features of aorta and the levels of LDL and HDL cholesterols in Wistar rats fed with high fat diet and canola oil. There were 20 Wistar rats in this study, divided into four groups: group A, the negative control; group B with high-fat diet (1 ml lard and 1 ml yolk daily); group C with high-fat diet and 0.1 ml of canola oil daily; and group D with high-fat diet and simvastatin 0.2 mg daily. The results showed elevated levels of LDL and HDL cholesterols in the treated groups compared to the control group. The histopathological features revealed many foam cells in the aorta wall (intima and media layers) of group B, whereas group C had fewer foam cells. No foam cells were found in group D. Conclusion: Although the mean LDL and HDL cholesterol levels of all treated groups were higher than of the control group, canola oil could reduce foam cell formation.Keywords: canola oil, foam cell, LDL and HDL cholesterols Abstrak: Minyak kanola merupakan salah satu sumber minyak nabati yang tinggi lemak tak jenuh yang dapat mengurangi risiko penyakit jantung koroner terutama aterosklerosis.

ABSTRACT Quinolone-induced chondrotoxicity in juvenile rats and multiple other species has been demonstrated previously. Identical damages can be induced in immature rats by feeding them a magnesium-deficient diet. The objective of the present study was to investigate whether, in reverse, oral supplementation with magnesium, vitamin E, or both can diminish the typical quinolone-induced arthropathy in juvenile Wistar rats. Four groups of 12 (6 male, 6 female) 24-day-old Wistar rats were each fed either normal feed (group A), a vitamin E-enriched diet (group B), a magnesium-enriched diet (group C), or a diet enriched with both vitamin E and magnesium (group D) for 10 days. All rats received two subcutaneous ciprofloxacin doses of 600 mg/kg of body weight on postnatal day 32. Two days later, the rats were sacrificed and cartilage samples from knee joints were examined under a light microscope for the presence of typical quinolone-induced joint cartilage lesions. In addition, magnesium, calcium, and vitamin E concentrations in cartilage and plasma were determined. In the samples from rats fed a normal diet (group A), 17 quinolone-induced joint cartilage lesions were observed. In groups fed an enriched diet, the incidence of specific lesions (n) was significantly lower: group B, n = 10 (41% reduction compared to the incidence for group A; P < 0.05); group C, n = 6 (65% reduction; P < 0.01); and group D, n = 3 (82% reduction; P < 0.01). In comparison to the standard diet, diets with magnesium and vitamin E supplementation resulted in significantly higher magnesium and vitamin E concentrations in plasma and articular cartilage. Supplementation with magnesium and vitamin E alone or in combination may relevantly diminish joint cartilage lesions induced by quinolones in immature rats, with an additive effect of combined supplementation. The data further support the proposed pathomechanism of quinolone-induced arthropathy and the crucial role of magnesium in immature joint cartilage.

Background: Gastric ulcer is one of the common diseases worldwide. Different parts of Azadirachta indica (Neem) tree has different uses in medicine for its beneficial properties and its leaves are also known to have anti ulcerant effect. Objective: This study was conducted to find out the protective role of Azadirachta indica (Neem) extract in the development of gastric ulcer. Materials and method: The study comprised of 30 Albino rats: Group-A, Group-B, Group-C, Group-D and Group-E having 6 rats in each group. The experiment was divided into 2 parts: Experiment-1 and Experiment-2. Experiment-1 comprised of Group-A and Group-B where Group-A served as control and was provided with normal saline (2 ml/kg body wt). In group-B rats ulcer was produced by administration of aqueous suspension of Aspirin (200 mg/kg body wt). All the rats were sacrificed after 4 hours to confirm gastric ulcer by histopathology. In Experiment-2, rats of Group-C served as disease control group and provided with normal saline (2ml/kg body wt). Group-D was provided with alcoholic extract of Azadirachtaindica leaves (150mg/kg body wt) and Group-E was provided with Ranitidine suspension (20mg/kg). After 8 days of treatment, animals were fasted for 24 hours. Then aqueous suspension of Aspirin (200 mg/kg body wt) was administered and after 4 hours all rats were sacrificed. Gross and microscopic examinations were performed to evaluate the results. Results: Histologically Aspirin treated rats showed ulcerated mucosa. Pretreatment with Neem extract showed protection against Aspirin induced gastric mucosal damage which was statistically highly significant (p<0.001). Conclusion: The study suggests that pretreatment with Azadirachta indica (Neem) leaves extract may be useful in prevention of Aspirin induced gastric ulcer. Delta Med Col J. Jul 2019 7(2): 61-65
