Hepatotoxicity caused by chemotherapeutic drugs (e.g., doxorubicin) is of critical concern in cancer therapy. This study focused on investigating the modulatory effects of diosmin against doxorubicin-induced hepatotoxicity in Male Wistar rats. Male Wistar rats were randomly divided into four groups: Group I was served as control, Group II was treated with doxorubicin (20 mg/kg, intraperitoneal, i.p.), Group III was treated with a combination of doxorubicin and low-dose diosmin (100 mg/kg orally), and Group IV was treated with a combination of doxorubicin and high-dose diosmin (200 mg/kg orally) supplementation. A single dose of doxorubicin (i.p.) caused hepatic impairment, as shown by increases in the concentrations of serum alanine aminotransferase, aspartate aminotransferase, and alkaline phosphatase. Doxorubicin produced histological abnormalities in the liver. In addition, a single injection of doxorubicin increased lipid peroxidation and reduced glutathione, catalase, and superoxide dismutase (SOD) levels. Importantly, pre-treatment with diosmin restored hepatic antioxidant factors and serum enzymatic activities and reduced the inflammatory and apoptotic-mediated proteins and genes. These findings demonstrate that diosmin has a protective effect against doxorubicin-induced hepatotoxicity.

The effect of repeated exposure of lower doses of lead and endosulfan were evaluated on apoptosis in male wistar rats. Rats of group I served as untreated control. Group II received drinking water with lead as lead acetate @100 ppm (Pb100). Group III was given feed containing technical grade endosulfan @ 10 ppm (E10). Group IV was exposed to Pb (100) +E (10). Splenocytes were analysed for estimating apoptotic percentage in rats. The results suggest that apoptotic percentage was not changed in the lower doses of endosulfan and lead when administered alone and also in combination in the present study

Chlorophyll Extracts

Background: Pharmacological therapy is one of the therapy modalities which carries the hepatic injury as one of its side effects. Nowadays, curcuma tablets has become choice of hepatoprotector. Other substance which has the possibilities of hepatoprotection activities is chlorophyll. The study is aimed to investigate the effect of papaya leaves chlorophyll extracts towards the serum AST and serum ALT levels on high-dose-paracetamol-induced Wistar rats. Materials and methods: This was an experimental study applying pretest-posttest controlled group design. Twenty eight Wistar rats 8-12 weeks age and weighted 185-220 grams assigned into four groups, namely group I (control), group II (paracetamol 750 mg/kg bw + no hepatoprotector agent), group III (paracetamol 750 mg/kg bw + curcuma 100 mg/kg bw), and group IV (paracetamol 750 mg/kg bw + papaya leaves chlorophyll extracts 300 mg/kg bw). The hepatoprotector agents were administered for a week, while the high dose paracetamol was administered for three consecutive days (day 5, 6, and 7). The pretest samples were drawn on the fifth day before the administration of high dose paracetamol, and the posttest samples were drawn on eightth day. Results: There were no difference among four groups on serum AST and serum ALT levels before the administration of high dose paracetamol, p=0.522 dan p=0.682, respectively. After the administration of high dose paracetamol, there were differences among four groups on both variables, both p=0.000. The post-hoc test showed that differences happened on all four groups (p<0.05).Conclusion: Chlorophyll extract of papaya leaves can inhibit liver injury on high-dose-paracetamol-induced-Wistar rats.

The objective of this study is to investigate the functions of parotid and pancreatic glands in response to intoxication with parathion-methyl (PM) and the effects of treatment in rats. Seventy-five male Wistar rats were divided equally into five groups: Group I, control; group II, received atropine and pralidoxime (2-PAM) for 24 h, but no PM; group III, oral PM but no atropine and 2-PAM; group IV, PM and atropine for 24 h and 2-PAM; group V, PM and atropine for 96 h and 2-PAM. After the administration of the chemicals, blood samples were drawn to test for amylase, lipase, acetylcholinesterase (AChE), and butyrylcholinesterase (BChE), while pancreatic and parotid glands of each rat were removed for light microscopic examination. Amylase levels were found significantly elevated in groups II, III, IV, and V, whereas lipase levels were supranormal in groups III, IV, and V. The blood levels of AChE were decreased in groups III and IV and BChE were decreased in II, III, IV, and V. No evidence of pancreatitis and parotitis was identified in the histopathologic evaluation in any group in 96 h; however, hyperchromasia, irregularity in nuclei, and binuclear cells were observed in all parotid glands in group V. Parotitis and pancreatitis were not evident; however, hyperamylasemia and hyperlipasemia were found, whereas various histologic changes in parotid glands were documented in the groups that were administered organophosphate and treatment.

Summary The effect of aqueous matured stem extract of Opuntia dillenii on selected biochemical parameters in Male Wistar rats was explored. Standard analytical methods were applied. Forty Wistar rats (80-100g) were used in the animal studies, separated into four groups. The control group was solely administered normal feed and saline, group I was administered 100mgkg−1 of the extract, group II received 300mgkg−1 of the extract and group III received 500 mg/kg−1 of the extract. A significant increase (p<0.05) in the activities of alanine aminotransferase (ALT) and alkaline phosphatase was observed in group II and III rats, as compared with the controls. A significant decrease in urea and creatinine concentrations was found only in group III rats against the controls. Also, a significant (p<0.05) decrease in triglyceride, total cholesterol, and low density lipoprotein (LDL)-cholesterol was seen in group II and group III rats when compared with the control. The hematological evaluation revealed a significant (p<0.05) decrease in red blood cell and hemoglobin levels in group III rats when compared with the control. The findings showed both beneficial and toxicological effects of the plant. Hence, for optimal therapeutic benefits, a further toxicological survey could still be carried out perhaps at higher doses.

Doxorubicin-induced cardiotoxicity is the leading cause of morbidity and mortality among cancer survivors. The present study was aimed to investigate the cardioprotective potential of methyl gallate; an active polyphenolic nutraceutical, against doxorubicin-induced cardiotoxicity in Wistar rats. Twenty-four female Wistar rats (150–200 g) were divided into four groups (n = 6) which consist of normal control (group I), doxorubicin control (group II), test-A (group III), and test-B (group IV). Group III and group IV animals were prophylactically treated with methyl gallate 150 mg/kg/day and 300 mg/kg/day orally, respectively, for seven days. Doxorubicin (25 mg/kg; single dose) was administered through an intraperitoneal route to group II, III, and IV animals on the seventh day to induce acute cardiotoxicity. On the 8th day, besides ECG analysis, serum CK, CK-MB, LDH, AST, MDA, and GSH were assayed. Following gross examination of isolated hearts, histopathological evaluation was performed by light microscopy. A significant ( p  < 0.05) cardiac injury, as well as oxidative stress, was observed in doxorubicin control rats in comparison to normal control rats. Methyl gallate at both the doses significantly ( p  < 0.05) reduced doxorubicin-induced ECG changes, dyslipidaemia, and elevation of CK, CK-MB, LDH, AST, MDA and increased GSH level. Methyl gallate reversed the doxorubicin-induced histopathological changes in the heart. The present study revealed that methyl gallate exerts cardioprotection against doxorubicin-induced cardiotoxicity in female Wistar rats by suppressing oxidative stress. Our study opens the perspective to clinical studies for consideration of methyl gallate as a potential chemoprotectant nutraceutical in the combination chemotherapy with doxorubicin to limit its cardiotoxicity.

Objectives: The objective of this study was to find the histologic and motor activity effect of lead on prenatally and postnatally exposed Wistar rats. Methods: In this study, twelve Wistar Rats were used and grouped into four groups of two females and one male. Group I rats served as the control and allowed feed and water freely. The rats in Group II were administered 500ppm of Pb through drinking water from gestation day 8 (GD8) to parturition (GD21). While Group III rats were given 500ppm of Pb in drinking water from postnatal day 1 (PND1) to PND21. The rats in the fourth group (Group IV) were given 500ppm of Pb from GD8 to PND21. Palmer grasp reflex was conducted to assess the motor activity of the rat pups. The animals were then humanely sacrificed and the frontal cortices were isolated for routine histological processing. Results: The histological study has shown normal neurons in the control group while degenerating cells exhibiting karyolysis, pyknosis, karyorrhexis, vacuolation were seen in the lead-treated groups. Group II and Group IV showed considerate deficit in their motor activity while Group III showed mild effect. Conclusion: From this study, lead exposure of Wistar rats at both prenatal and postnatal period of development has effect on the histology of the frontal cortex as well as on their motor activity.

Background: Children require more nutrition as organs grow fast in this age group. Due to abundance of various commercial health supplements in market, parents are often confused about selection of health supplements. Traditional foods are rich source of various nutrients required by growing children. We conducted a study to compare strength, stamina and growth enhancing ability of commercial health supplement and natural health supplement on wistar rats.Methods: Total of 24 wistar rats were included. Animals were divided in four groups. Each group of rats except control group were receiving health supplements. Group I, group II, group III and group IV were receiving health supplement I, health supplement II, natural health supplement and no health supplement (control group) for 60 days. Strength and stamina of wistar rats in each group were analysed using grip strength meter and swim stress test, growth of rats in each group were analysed by measuring body length, tail length and body weight. Group of rat showing maximum growth (body length, tail length and body weight), strength and stamina were analysed.Results: Group II rats showed greater strength and stamina followed by group I, group III and group IV respectively. Group I rats showed maximum growth followed by group II, group III and group IV respectively.Conclusions: In the current study we found that strength and stamina were greater in group II rats followed by group I, group III and group IV respectively also group I rats showed maximum growth  followed by group II, group III and group IV respectively.

AIM: This study was to assess the prophylactic and curative effects of Essentiale forte (ESF) on carbon tetrachloride (CCl4) induced liver damage in Wistar rats.MATERIALS AND METHODS: Twenty-four adult Wistar rats were randomly divided into four groups of six rats each. Group I (control group) received 0.3 ml/kg/day of propylene glycol for one month; group II (toxic control) was given 0.7 ml/kg/day of CCl4 dissolved in olive oil (1:1,v/v) orally for 7 days; group III (prophylactic group) received 4.3 mg/kg/day of ESF for one month followed by CCl4 for one week; group IV (curative group) was treated with CCl4 for one week and subsequently received ESF (4.3 mg/kg/day) for one month. Half of the rats were sacrificed at active period, the other half after a 2-week recovery period.RESULTS: The activities of serum AST, ALT, ALP, total bilirubin level were significantly higher, total protein and GSH levels were significantly reduced in the toxic control group compared to the control group. Group III had significantly higher AST and ALT activities compared to the control rats at active period, whereas after the recovery period no significant differences were observed in almost all the parameters. Moreover, no significant differences in the parameters mentioned above were observed in group IV compared to the control rats at active and recovery period.CONCLUSION: The results of this study showed that Essential forte was better as a curative agent rather than a prophylactic agent in rats.

Aluminium (Al) is presents in many manufactured foods, medicines and is also added to drinking water for purification purposes. Human exposure to Al has been increasing over the last decades. Al exposure and neurological impairments demonstrate mixed findings. The cerebral cortex is a sheet of neural tissue that is outer-most to the cerebrum of the mammalian brain and it plays a key role in memory, attention, perceptual awareness, thought, language, and consciousness.The objectives of this study was to investigate the possible effects that aluminium Chloride could have on the histology of cerebral cortex. Total of twenty adult wistar rats were used for this experiment. The wistar rats were divided into five groups; group I was the control, group II received 475mg/Kg, group III received 950mg/kg, group IV received 1,425mg/kg and group V received 1,900mg/kg via oral intubation for a duration of Eight weeks. The wistar rats were humanly sacrificed and the brain was removed and immediately fixed in bouin fluid. The histological observations of the aluminium treated groups revealed extensive neuronal vacuolation and necrosis (neuro-degeneration) of the cerebral cortex of wistar rats.Based on our observations, we therefore conclude that Aluminium chloride exposure has neurodegenerative effects on the histology of cerebral cortex of adult wistar rats especially at higher dose. Therefore, caution should be taken in its usage.

Introduction: Honey is a naturally occurring sweet substance of plant origin composed mainly of fructose, glucose, water, antioxidants and other constituents. Its enormous constituents confer it with medicinal and nutritive usefulness. Objectives: To assess the modulatory effects of honey on gastric acidity and plasma postprandial bicarbonate in wistar rats. Method: A total of 24 male wistar rats weighing 200-250g were divided into four groups of six rats each; Group I served as control, Group II received 50% Honey (10ml/kg), Group III received omeprazole (20mg/kg) and Group IV received a combination of Omeprazole and Honey. The pH of gastric effluents in each rat was measured 15, 30 and 45mins using a pH meter after administration of the respective substances in each group. Result and Discussion: Both honey and omeprazole respectively caused significant increases in the pH of gastric effluents, however, while that of honey was slow and steady, that of omeprazole was sharp and sustained. The 45-min pH level of omeprazole group was significantly higher than that of honey group. The combined group showed an initial sharp rise similar to omeprazole alone but gradually declined in the succeeding time interval. A combination of omeprazole and honey resulted in 27% reduction in the postprandial serum bicarbonate whereas omeprazole alone caused 41% reduction Conclusion: The present study concludes that honey modulated gastric pH to levels possibly favourable to gastric function by either a direct action of reducing gastric acidity or acting as an antacid or both. Honey therefore could be described as a buffer in omeprazole stimulated gastric acid inhibition and a potential antacid. Keywords: Honey, Gastric acidity, Gastric pH, bicarbonate.
