The protective effect of natural bees' honey to the liver of male albino rats against melamine toxicity was studied. Melamine supplementation at a dose of 20000 ppm in the diet for 28 days induced adverse effects on the liver, decreased serum total protein and increased liver enzyme: alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Histological changes of the melamine supplemented group showed necrosis in the hepatic tissues around the central veins of the liver and precipitation of melamine crystals. Treating the male albino rats (that were presupplemented regularly with 20000 ppm melamine) with natural bees' honey at a dose of 2.5 g/kg body weight for 28 days improved both liver functions and increased serum protein. In addition, a positive impact on the shape of the cells after treatment with honey compared to the positive melamine supplemented group was observed. In conclusion, the results of this study revealed that the use of natural bees' honey has the ability to protect the liver of rats against the toxic effects of melamine.

The present investigation was aimed to determine the effect of sub-chronic exposure to Solignum<sup>®</sup>, a permethrin-containing wood preservative on biochemical and histological changes in liver and kidneys of male Wistar albino rats. Thirty-two male rats were randomly divided into four groups: control and three treatment concentrations containing 8 rats each. The treatment groups were exposed to Solignum<sup>®</sup> at dose rates of 100, 200 and 400 mg/kg body weight (BW) respectively per day orally for four weeks. Data obtained from the study showed a progressive increase in the body weight of rats in control whereas, rats treated with different concentrations (100, 200 and 400 mg/kg BW) of Solignum<sup>®</sup> decreased significantly (≤0.05) especially at the end of the second and fourth week when compared with control. On the other hand, there was a significant decrease in the relative liver weights of rats treated with 100 and 200 mg/kg BW Solignum<sup>®</sup> while rats treated with 400 mg/kg BW showed a significant increase when compared with control. The relative weight of kidneys in experimental groups increased significantly when compared with control. Biochemical analysis results illustrated that there was a significant increase in marker enzymes namely alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase activity at the end of the fourth week. Similarly, total bilirubin, serum urea, creatinine and electrolytes (Na<sup>+</sup>, K<sup>+</sup> and Cl<sup>-</sup>) levels increased in a dose dependent manner in treated rats when compared with untreated control group. Serum total protein decreased significantly in experimental rats when compared with control. However, cholesterol and triglycerides showed no significant difference when compared with control. Histopathological examination of hepatocytes in treated rats was characterized by mild periportal inflammatory cells and cytoplasmic degeneration. Furthermore, histopathological examination of rat kidneys revealed inflammatory cells, congested vessel and interstitial hemorrhage in rats treated with Solignum<sup>®</sup>. Therefore, this present study is aimed to evaluate the hepatotoxic and nephrotoxic potentials associated with sub-chronic exposure to the commercial pesticide Solignum<sup>®</sup>.

The study was aimed at investigate the effect of methanolic extract of Buchanania axillaris linn. (Anacardiaceae) on general mating behaviour, libido, and adverse effects on sexually normal male albino rats. Methanolic extract was administered orally at the dose of 100, 200, and 400 mg / kg, to different groups of male rats (n = 8) once a day for 14 days. All the doses resulted in significant increase in mount frequency, intromission frequency and anogenital sniffing when compared to normal. The methanolic extract of Buchanania axillaris leaves at higher concentration (400 mg/kg body weight) showed significant aphrodisiac activity on male Wister albino rats as evidenced by an increase in number of mounts and mating performance. Thus, in experimental rats, the results of the present study suggest that the methanolic extracts of Buchanania axillaris exert significant aphrodisiac activity

Background: Cardiotoxicity (CT) can be developed due to prolonged use of higher doses of some drugs, exposure to some chemicals, toxins or infectious agents and also by some disease conditions. Natural plant foods such as peanut (Arachis hypogaea L.) may have free radical scavenging activity, thereby can be used for the prevention and management of heart disease. Objective: To observe the protective effect of peanut (Arachis hypogaea L.) and its combined action with propranolol on histological changes in isoproterenol induced cardiotoxic rats. Method: This experimental study was carried out in the Department of Physiology, Sir Salimullah Medical College, Dhaka in 2012. For this purpose, 20 Wistar albino rats, age 85- 100 days, weighing 120 to 150g (initial body weight) were included in the peanut treated group. They were sub-divided into CT-ISO-P (Cardiotoxic group with isoproterenol after peanut treatment) and CT-ISO-C (Cardiotoxic group with isoproterenol after combined treatment of peanut and propranolol). Age and weight matched 30 Wistar albino rats without any peanut supplementation were taken and sub-divided into three sub-groups, BC (Baseline control), CT-ISO (Cardiotoxic group with isoproterenol) and CT-ISO-PRO (Cardiotoxic group with isoproterenol after propranolol treatment). Each sub-group consisted of 10 rats. After taking final body weight all the rats were sacrificed on 22nd day. The heart was removed and preserved in 10% formalin for histological processing. To find out the histopathological changes of heart tissue, histological slides were prepared and were observed under microscope in the Department of Pathology, SSMC. Histological findings were categorized by scoring as mild, moderate and severe histological changes. The statistical analysis was done by one way ANOVA and Bonferroni test as applicable. Result: In this study, percent change from initial body weight to final body weight was significantly (p<0.01) lower both in CT-ISO-P and CT-ISO-C as compared to that of BC. Again, histological score was significantly (p<0.01) higher in CT-ISO in comparison to that of BC. Moreover, these scores were significantly lower in CTISO- PRO (p<0.01), CT-ISO-P (p<0.05) and CT-ISO-C (p<0.05) in comparison to that of CT-ISO. Similarly, this score was significantly (p<0.01) lower in CT-ISO-C when compared to that of CT-ISO-P. Conclusion: The present study revealed that peanut can preserve almost normal histological architecture of heart tissue in isoproterenol induced cardiotoxic rats. However, the combined therapy of peanut with propranolol showed synergistic effect on preventing histological changes in heart tissue.

To investigate the antihyperglycemic and antihyperlipidemic effect of Momordica charantia (Karala), the aqueous extract of the Karala fruit was tested on streptozotocin (STZ)-induced diabetic rats. Thirty six albino rats were used in the experiment, 30 diabetic and the remaining six as negative control (T1). Diabetes was induced by administering (injecting) STZ at dose of 55mg/kg body weight. Thirty diabetic animals were randomly divided into five groups such as diabetic control group (T2) without any application of treatment, and groups T3,T4,T5 and T6 were treated with aqueous extract of Karala fruits daily at the doses of 250,    500 and 750mg/kg and glibenclamide (at a dose of 5mg/kg body weight) respectively. The body weight was taken and blood samples were collected from individual animal to determine glucose levels at 15 day interval up to 90 days. In addition, Asparate  Transaminenase(AST), Alanine Transaminenase(ALT), Alkaline Phosphatase(ALP), Total cholesterol (TCh) and Triglyceride (TGA) were determined at day 15 and at the end of the experiment. All three doses of Karala extracts reduced diabetic induced blood sugar and the reduction is comparable with standard glibenclamide (GLM) dose particularly with higher doses Karala extracts (500 and 750mg). Karala also prevented body weight loss due to induced diabetes as did by GLM treatment.. The treatment also resulted in a significant reduction of Asparate Transaminenase(AST), Alanine Transaminenase(ALT), Alkaline Phosphatase(ALP), Total cholesterol (TCh) and Triglyceride (TGA) activities of treated rats when compared to the STZ induced  diabetic rats. Higher doses of Karala (500 and 750mg/kg) are as effective as standard GLM dose on measured variables. This study demonstrated that Karala has hyperglycemia and antihyperlipidemic effect against STZ induced diabetic rats. These findings open the possibility of using Karala extract to treat diabetic animal and human patients although further research is warranted. DOI: http://dx.doi.org/10.3329/jesnr.v5i1.11550 J.

Membrane bound adenosine triphosphatases (ATPases) shed a massive function into the contraction and relaxation of the heart muscle via keeping the normal ion levels within the myocyte. The current study aims to assess the potency of Zanthoxylum armatum (Z. armatum) fruit on membrane bound ATPases and ions in Isoproterenol (ISO) induced myocardial infracted rats. The hydroethanolic extract of Z. armatum fruit was administered at a dose of 200 and 400mg/kg body weight for 30 days to male Wistar albino rats. On 28th and 29th day, ISO (8.5mg/100g body weight) used to be administered to induce myocardial infarction (MI). ISO treated rats confirmed a significant increase in the levels of tissue sodium (Na+) and calcium (Ca2+) ions and membrane bound Ca2+ ATPase then Mg2+ ATPase activity. A significant decrease in tissue potassium (K+), Na +/K+ ATPase was observed which indicates membrane destabilization. Pretreatment with hydroethanolic extract of Z. armatum fruit to ISO induced rats significantly (p<0.05) prevented the altered membrane bound enzymes to near normal status. The findings of the present study indicate the protective effect of Z. armatum fruit on altered ion pumps and destabilization on the cardiac membrane into ISO induced MI rats which might also be due to the presence of phytoconstituents.

Aim: The aim of this study is to compare the protective effect of zinc nanoparticle and zinc supplement against carbamazepine induced reproductive changes in male Albino rats. Study Design: In this experiment, 60 Male albino rats were used which are divided into six groups of 10 rats each. The first group was used as the control for the experiment and they were given distilled water. The second Group, Group 2 were administered with 20 mg/kg body weight of carbamazepine, group 3 were administered with 20 mg/kg of carbamazepine plus 10 mg/kg of zinc nanoparticle and Group 4 were administered with 20 mg/kg of carbamazepine plus 10 mg/kg of zinc supplement while group 5 were administered with 10 mg/kg of zinc nanoparticle and also group 6 were administered with 10 mg/kg of zinc supplement only. Place and Duration of Study: Department of Biochemistry, Bells University of technology, Ota, Ogun State Nigeria, the research was carried out from February to June, 2018. Methodology: Zinc nanoparticle extraction was carried out to obtained Zinc nanoparticle. A 60 male albino rats with weight ranging from 140 g - 230 g were used. They were fed with normal rat chow and were allowed to acclimatize for a period of two weeks. They were then divided into six groups according to their body weight which contained the test groups and the control group. The rats were sacrificed after two weeks of test administration. They were allowed an overnight fast (24 hours). The cervical dislocation was done, and the blood was collected from the heart, in to a lithium heparinized bottle. The testes of the rats were also collected and stored in a sample bottle containing buffer and stored, the liver, kidney and the brain were collected too. The rats liver and testes were weight and macerated in 5 times the volume of the actual organ weight using homogenate buffer (phosphate buffer). The resulting homogenate was centrifuge at 10000 rmp speed for 15 mins then it was removed from the centrifuge and the supernatant was decanted and stored below 4°C. Result: The group administered with carbamazepine only show significant decreased in the level of follicle stimulating hormone, luteinizing hormone and testosterone when compared with control group, followed by the group administered with zinc nanoparticle only. However, group 6 and group 4 that were administered with zinc supplement and zinc supplement plus carbamazepine showed a significant increase in the level of these hormones when compared with control group, while group 6 which were administered with carbamazepine and zinc nanoparticle showed no significant different when compared with control group. In addition carbamazepine alone significantly increased the level of alanine transaminase (ALT) in the liver and also the group administered with zinc nanoparticle alone significantly increased the level of aspartate transaminase (AST) with decrease in the level of ALT. However, the groups administered with zinc supplement alone and in combination with carbamazepine reduced ALT and AST levels in the liver. Conclusion: Therefore, this study suggest that, carbamazepine induced toxicity by affecting the level of sex hormones and activities of the kidney in the male albino rats, and also zinc nanoparticle have more protective effect than zinc supplement against carbamazepine toxicity.

Dose Levels

A rise in systolic blood pressure due to the administration of 0.4 or 0.5 μg of aldosterone per 100 g body weight to young male rats, over a period of 3 to 6 months, has been confirmed in two separate experiments. This effect was observed whether the aldosterone was given 3 days a week or 6 days a week, and whether dissolved in aqueous ethanol or in oil. Equal doses of 9-α-fluorohydrocortisone and of 2-methyl-9-α-fluorohydrocortisone produced similar though somewhat less consistent effects. When 4 or 5 μg of reserpine was administered along with aldosterone there was no clear evidence of a protective effect. Reserpine alone at these low dose levels was somewhat toxic in the rat and led to a rise in blood pressure.
