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.

Abstract: Liver is the largest organ in the abdominal cavity. As the center of metabolism in the body, liver is potentially damaged by exposure of toxic substances, inter alia carbon tetrachloride (CCl4). Metabolism of carbon tetrachloride (CCl4) produces CCl3 free radicals that can damage the liver. In Indonesia, there are a lot of natural ingredients that have antioxidant properties, such as tomato. Lycopene in tomatoes contains antioxidant compounds that can prevent damages due to free radical. This study aimed to obtain liver histopathological changes of wistar rats fed with tomato juice after being induced of carbon tetrachloride (CCl4). This was an experimental study, using 10 wistar rats which were divided into 4 groups. Group I was the negative control; group II was induced with CCl4 0,05 cc/day and was terminated on day 6; group III was induced with CCl4 0,05 cc/day and was given tomato juice 3 ml/day, and terminated on day 13; group IV was induced by CCl4 0,05 cc/day, given regular pellets, and terminated on day 13. The results showed that group II had histopathological changes of the liver indicating fatty liver, meanwhile group III showed regeneration of nearly all liver cells. Conclusion: Administration of tomato juice after the induction of 3 ml carbon tetrachloride (CCl4) for 7 day showed regeneration of almost all liver cells. Keywords: histopathological changes of the liver, carbon tetrachloride, tomato juice.   Abstrak: Hati merupakan organ terbesar dalam rongga abdomen, dan pusat metabolisme tubuh dengan fungsi yang sangat kompleks dan sangat berpotensi mengalami kerusakan akibat terpapar oleh bahan-bahan toksik, salah satunya yaitu karbon tertraklorida (CCL4).

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: Hyperlipidemia is a well known risk factor for cardiovascular disease, especially atherosclerotic coronary artery disease. Peroxisome proliferator activated receptor α (PPARα), a member of this nuclear receptor family, has emerged as an important player in this scenario, with evidence supporting a central co-ordinated role in the regulation of fatty acid oxidation, lipid and lipoprotein metabolism and inflammatory and vascular responses, all of which would be predicted to reduce atherosclerotic risk. The low-density lipoprotein (LDL) receptor (LDLR) is the primary pathway for removal of cholesterol from the circulation, and its activity is meticulously governed by intracellular cholesterol levels. Hence in this study we investigated the effect of Lutein on PPARα and LDLR expression in liver of wistar rats.Methods: Male Wistar rats were divided into 6 groups of 6 each. Group I served as control. Group II III, IV, V and VI rats were received high cholesterol diet. Group III was treated with Atorvastatin 5mg/kg. Group IV, V and VI rats were treated with 25mg/kg, 50mg/kg and 100mg/kg of Lutein. After 16 weeks, liver tissue samples were collected from all the groups of animals to evaluate the expression of PPARα and LDLR.Results: The expression of Peroxisome proliferator activated receptor α and low-density lipoprotein (LDL) receptor (LDLR) was significantly increased in Lutein treated hypercholesterolemic male wistar rats.Conclusions: The results of this study indicate that Lutein activates LDL receptor and PPARα in hypercholesterolemic male wistar rats.

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.

Natural products are gaining much importance in light of the serious side effects posed by drugs of chemical origin. High intake of foods rich in antioxidants reduces the risk of neurodegenerative disorders. Traditionally, Allium sativum L.(garlic) and Allium cepa. L (onion) has received considerable attention for their therapeutic benefits around the globe. The present study assesses the free radical scavenging role of Allium sativum and Allium cepa in cerebral cortex, striatum, and hippocampus. Adult wistar rats of either sex were grouped as control group (Group I) treated with normal saline and the two experimental group were treated with the aqueous bulbous extracts of dehydrated Allium sativum (Group II) and Allium cepa (Group III) was considered as treated groups. Homogenates of hippocampus, striatum and cerebral cortex were analyzed for biochemical and neuronal analysis. LD50 value of these extracts in rats was found at a dose of 500 mg/kg BW. A Significant decline (P<0.05) in the MDA level was observed in the hippocampus, striatum and cerebral cortex in group II when compared to group III. Total antioxidant level, GSH, SOD level was significantly high (P<0.001) in the treated groups. Neuronal increase was significant in Group II (P < 0.01) when compared to Group III. Allium sativum and Allium cepa was found to have a challenging role in hampering oxidative stress in Hippocampus, striatum and cerebral cortex, the target regions in neurological disorders. However, ample number of studies are required to establish their mechanism of action as a progression to clinical approach.

Abstract Male Wistar rats were divided into 3 groups: Group I. Rats given the triamcinolone daily by gastric catheter all developed neutrophilia accompanied by lymphopenia. Group II. Rats given daily intraperitoneal injections of plasma from normal rats manifested no significant alteration in the peripheral blood elements. Group III. Rats given daily intraperitoneal injections of plasma from rats given triamcinolone invariably developed neutrophilia without lymphopenia. Studies of the bone marrow of these groups at the end of the experiments revealed increased myeloid:erythroid ratios in Groups I and III but not II. It is therefore believed that this experiment suggests the existence of a neutrophilia-promoting factor in the plasma following the administration of triamcinolone.

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.

Abstract Objectives Exposure to light-at-night (LAN) has been reported to impair blood glucose regulation. The liver modulates blood glucose through mechanisms influenced by several factors that include peroxisome proliferator-activated receptor gamma coactivator-1alpha (PGC-1α) and glucose-6-phosphatase (G6Pase). This study investigated the effect of intermittent exposure to green and white LAN on some hepatic glucose regulatory factors in male Wistar rats. Methods Animals were divided into three equal groups. Group I (control) was exposed to normal housing conditions. Groups II and III were each daily exposed to either green or white LAN for 2 h (7–9 pm) for 14 days. Body weight and blood glucose was monitored on days 0, 7, and 14. Thereafter, retro-orbital sinus blood was obtained after light thiopental anaesthesia and serum insulin was determined. Liver samples were also obtained and evaluated for glycogen, PGC-1α, and G6Pase activity. Insulin resistance was estimated using the HOMA-IR equation. Results Body weight and blood glucose on days 7 and 14 increased in groups II and III compared to control. Hepatic PGC-1α and G6Pase increased in group II (2.33 ± 0.31; 2.07 ± 0.22) and III (2.31 ± 0.20; 0.98 ± 0.23) compared to control (1.73 ± 0.21; 0.47 ± 0.11). Hepatic glycogen was 71.8 and 82.4% reduced in groups II and III compared to control. Insulin in group II increased (63.6%) whiles group III values reduced (27.3%) compared to control. Insulin resistance increased in group II (0.29 ± 0.09) compared to control (0.12 ± 0.03) and group III (0.11 ± 0.03), respectively. Conclusions Exposure to 2 h green and white LAN in the early dark phase increases hepatic glycogenolysis and gluconeogenetic activities resulting in increased blood glucose. In male Wistar rats, exposure to green but not white LAN may predispose to insulin resistance.
