Abstract Resveratrol has antioxidant, anti-inflammatory, lipolytic, and antifibrotic properties, which may be useful in supplementation of obese patients and with liver problems. This study evaluated the effects of 6-week resveratrol supplementation on the lipid profile and liver function of female Wistar rats fed a high-fat diet to induce obesity. Sixty-four Wistar rats were divided into 4 groups (n = 16): the control group (C); the control obese group (CO); the resveratrol group (R); and the resveratrol obese group (RO). At the end of the experiment, the animals were anesthetized for blood collection and subsequent euthanasia for collection of liver biopsy. The parameters for body weight, liver weight, retroperitoneal fat weight, serum lipid and liver profiles and histopathological analysis were evaluated. The 6-week resveratrol administration did not induce weight loss nor did it reduce the lipid profile; however, it decreased the liver enzymes aspartate aminotransferase (AST) and alkaline phosphatase (ALP) and reduced the incidence of steatosis (75.0%) in group RO compared with group CO (81.2%). Thus, we concluded that resveratrol supplementation for the short period of six weeks had a beneficial effect on liver function by reducing hepatic steatosis and the liver enzymes AST and ALP in obese female rats.

ABSTRACT Background and objective Polycystic ovary syndrome (PCOS) can be induced in Wistar rats by over production of nitric oxide (NO). This study evaluated the efficacy of naloxone on the breeding characteristics of rats suffering from nitric oxide induced PCOS. Materials and methods Twenty-four female Wistar rats(200–250 gm) were kept as virgin under standard conditions. They were divided into four groups (n = 6). One group of the animals received L-arginine (50 mg/kg) intraperitoneally (i.p.) for 9 days/once a day. Another group was administered naloxone hydrochloride (0.4 mg/kg, i.p.) prior to injection of L-arginine. The third group was injected solely naloxone. Control group received saline solution (1 ml/kg, i.p.). After the treatments, all female rats were coupled with the intact males. They were then separated by observation of vaginal plaques; it was considered as day 0 of pregnancy. Eventually, they were operated on days 18 to 19 of the gestation to collect the animals’ ovaries. The samples were studied for pathological evidence. The fetal number and weight along with the fetal crown-rump length (CRL) were measured. Results The ovaries obtained from the L-arginine treated group had large cysts with thickened granulosa cell layer in contrast to those of the control or naloxone treated rats (p < 0.0001). The number of fetus though showed a decrease in the L-arginine treated rats (3 ± 1), but the fetal weight or fetal CRL did not change (p > 0.05). Conclusion This study may clearly illustrate the polycystic characteristics in the L-arginine treated group. It may particularly display the breeding efficacy of naloxone in rats with PCOS.

Abstract Introduction: Calabash chalk is a naturally occurring mineral, chiefly composed of fossilized sea shells. It is prepared from clay and mud mixed with other ingredients, including lead, arsenic, sand and wood ash. Clay consumption is correlated with pregnancy, and also to eliminate morning sickness in women. The aim of this study is to evaluate the effects of calabash chalk on the ovarian function in adult female Wistar rats. Methods: Eighteen (18) adult female Wistar rats. Group A served as the control group, group B received 40 mg/kg body weight of Non-salted calabash chalk while group C received 40 mg/kg body weight of Salted calabash chalk for 14 days. On day 15, the animals were sacrificed for histological and biochemical examination. Results: Results showed a significant (P< 0.05) reduction in follicle stimulating hormone (FSH) levels of the treatment groups when compared with the control group and an increase in luteinizing hormone (LH) levels of the treatment groups when compared with the control group. Histological examination of the ovaries showed severe deterioration of the ovarian follicles, necrosis and follicular atresia. Conclusion: Calabash chalk is toxic to ovarian function. These alterations have been shown to be the leading cause ofinfertility in female rats. Hence, proper monitoring, education, and regulation of the product is needed.

AbstractAdministration of estradiol or calcium, or combined, represents the classical therapeutic approach in the treatment of some menopausal symptoms. We have studied the effects of estradiol dipropionate (EDP) and calcium glucoheptonate (Ca) on morphological and hormonal features of the adrenal gland in 14-month-old female Wistar rats. The animals were treated with EDP (0.625 mg/kg b.w.) or Ca (11.4 mg/kg b.w.) daily for two weeks, with control rats receiving vehicle alone by the same schedule. The cell volumes in the zona glomerulosa (ZG) and zona fasciculata (ZF) were 11.2% and 5.5% greater (P<0.05) and in the zona reticularis (ZR) 13.0% smaller (P<0.05) in the EDP group than in the control group. In the Ca group, cell volume in the ZG was increased by 5.6% (P<0.05), while cell volumes in the ZF and ZR were decreased by 26.0% and 14.7%, respectively (P<0.05), in comparison with control values. Serum aldosterone and corticosterone concentrations were higher in the EDP-treated (by 27.8% and 19.8%, respectively) and Ca-treated (by 80.0% and 24.1%, respectively) groups in comparison with the control group (P<0.05). These data suggest that EDP and Ca treatments have stimulatory effects on the ZG and ZF, but inhibitory effects on the ZR in middle-aged female rats.

Objective: The objective of the study was to evaluate the subchronic toxicity of Sauropus androgynus L. Merr. leaves soup. Methods: Subchronic oral toxicity tests were carried out for 28 days in female Wistar rats using conventional methods. Thirty rats were divided into six groups, namely, one control group and three test groups with each extract being given at a dose of 500 mg/kg body weight (BW), 1000 mg/kg BW, and 3000 mg/kg BW, and one group satellite control and satellite test group with doses of 3000 mg/kg BW were carried out for 14 days after 28 days of treatment to see the effects of reversibility. All rat groups were observed for behavior, development of BW, serum glutamic pyruvic transaminase (SGPT), serum glutamic oxaloacetic transaminase (SGOT), creatinine serum, ratio of liver and lung organs to BW, and histology of liver and lung. Results: The macroscopic observation of rat’s lung and rat weight ratio did not show a significant difference to the control group (p>0.05). In addition, the ratio of liver volume to BW was significantly different between the doses of 1000 mg/kg BW and 3000 mg/kg BW with satellite groups 3000 mg/kg BW (p<0.05). Levels of SGOT and SGPT as well as liver and lung histopathology scores did not show a significant difference to the control group (p>0.05). However, creatinine serum had the highest increase at a dose of 500 mg/kg BW and a dose of 1000 mg/kg BW. Reversibility effects were not seen after 14 days of the past day given Sauropus androgynous soup for 28 days in female Wistar rats. Conclusion: The given of S. androgynous soup for 28 days for female Wistar rats did not show any specific toxicity effect so that its use was relatively safe for the consumption under 30 days. This study is expected to be the information source about the safety profile of S. androgynus leaves soup consumption.

Background. The objective of this study is to observe if mild hyperuricemia and a high-fructose diet influence the cardiovascular and metabolic systems in hypogonadic female Wistar rats compared to normogonadic female rats. Methods. Fifty-six (56) adult female Wistar rats were used in the present work. Animals were divided into two groups: normogonadic (NGN) and hypogonadic (HGN). These groups were also divided into four subgroups in accordance with the treatment: control with only water (C), fructose (F), oxonic acid (OA), and fructose + oxonic acid (FOA). Lipid profile, glycemia, uric acid, and creatinine determinations were assessed. Cardiovascular changes were evaluated by measuring blood pressure, myocyte volume, fibrosis, and intima-media aortic thickness. Results. HGN rats had higher levels of total cholesterol (TC) (p<0.01) and noHDLc (p<0.01), in addition to higher levels of uric acid (p<0.05). The OA group significantly increased myocyte volume (p<0.0001) and the percentage of fibrosis as well as the group receiving FOA (p<0.001) in both gonadal conditions, being greater in the HGN group. Hypogonadic animals presented a worse lipid profile. Conclusion. Mild hyperuricemia produces hypertension together with changes in the cardiac hypertrophy, fibrosis, and increased thickness of the intima media in hypogonadic rats fed high-fructose diet.

In obesity, there is an accumulation of adipocytes which produces adipokine that are pro-inflammatory substance, such as leptin and MCP-1 and anti-inflammatory substance, such as adiponectin, while the bioavailability of vitamin D is decreased. This research aimed to study the effect of vitamin D administration on leptin, MCP-1, and adiponectin levels in adipose tissue rats with obesity. Vitamin D was administered to the obese model of 6-9 months old female Wistar rats. This experiment was a randomized control group design with a post-test group design only. Twenty-seven (27) female obese Wistar rats were included in this study. The animals were divided randomly into 3 groups: 9 rats were given 2400 IU vitamin D (group A), 9 rats were given 800 IU vitamin D (group B) and 9 rats were given a placebo as control (group C). The administration of Vitamin D was given once daily for 8 weeks. The visceral adipose tissue was taken to measure the level of leptin, adiponectin and mRNA MCP-1. Data among groups was analyzed by using one-way ANOVA and followed by LSD test, at a significance level of p <0.05. The lowest level of leptin (1059.15+135.20 pg/ml) and mRNA MCP-1 (2.36 + 0.75 fg/ml) and the highest adiponectin level (3.43 + 0.47 ng/ml) were found in group A. In conclusion, oral administration of vitamin D (2400 IU) decreased pro-inflammatory substances, such as leptin and mRNA MCP-1 and increased anti-inflammatory substances, such as adiponectin, in visceral adipose tissue of obese female Wistar rats.

Bisphenol A (BPA)—an endocrine disruptor xenoestrogen—is widely spread in the environment. Lycopene (LYC) is an antioxidant phytochemical carotenoid. The hereby study was designed to verify the deleterious effect of BPA on cyclic female rats’ hepatic tissue as well as evaluation of the effect of LYC toward BPA hepatic perturbation. Twenty-eight female Wistar rats were allocated equally into four groups: control group, LYC group (10 mg/kg B.wt), BPA group (10 mg/kg B.wt), and BPA + LYC group (the same doses as former groups). The treatments were given daily via gavage to the rats for 30 days. The rats in BPA displayed high activities of serum liver enzymes with low levels of total proteins (TP) and albumin. Moreover, BPA induced hepatic oxidative stress via depletion of antioxidant enzymes concomitant with augmentation of lipid peroxidation, increased comet tail DNA %, and overexpression of caspase-3. Meanwhile, LYC administration reduced the cytotoxic effects of BPA on hepatic tissue, through improving the liver function biomarkers and oxidant-antioxidant state as well as DNA damage around the control values. These findings were confirmed by hepatic histopathological examination. Finally, LYC credited to have a noticeable protective effect versus BPA provoked oxidative injury and apoptosis of the liver tissue.

Human patients with Type1 diabetes and inadequate metabolic control have been found to exhibit a high prevalence of infertility but the exact mechanism by which this happens has not been fully elucidated. Alterations in the levels of lipids and electrolytes are considered to be good indications of some certain diseases including diabetes. This study aims at elucidating the impact of diabetes on the reproductive functions of male and female subjects as well as the responses of lipid profile which could be a determining factor affecting diabetic condition, to Alloxan-induced diabetes using male and female Wistar rats. To explore this, various hormonal assays assessing reproductive hormones such as Follicle stimulating hormone (FSH); Luteinizing hormone (LH); Prolactin hormone (PRL); lipid profile analyses and electrolytes measurements were employed. Our results showed that diabetes induce significant reduction in the levels of FSH and LH in both male and female rats (p<0.0001); significant reduction in the levels of LH in male (p<0.01) and female (p<0.0001); significant increase in the levels of prolactin (PRL) in male (p<0.05) and female (p<0.0001) ; significant increases in cholesterol levels in both male and female rats (p<0.01), an indication that diabetes is accompanied in most cases by hypercholesterolemia and triglycerides levels in both male (p<0.01) and female (p<0.0005) rats when compared to the control rats. The results obtained in this study shed more light on the mechanism by which fertility in male and female subjects is affected by diabetes and suggest possible mechanisms by which infertility could result from diabetes.

Plants and their metabolites have been used in the treatment of various disease conditions from time immemorial. This study investigated the effect of hydro-ethanolic extract of pods of Xylopia aethiopica on reproductive hormone (follicle stimulating hormone (FSH), luteinizing hormone (LH) and progesterone) in female Wistar rats. Thirty female wistar rats were randomly divided into 5 groups of six animals per group, per cage (n=6). Group A served as the normal control group and was administered distilled water while group B served as positive control and was administered 5 mg of standard drug (Clomid-Clomiphene Citrate). Groups C, D and E served as the treatment group and was administered 50 mg/kg, 100 mg/kg and 200 mg/kg extract of X. aethiopica respectively for seven days. Administration of drugs and extract was done via oral route. The rats were thereafter copulated with their male counterparts for 72 hours and the female rats were observed throughout their gestation and the numbers of litters produced were recorded. The hormonal assay was carried out using Enzyme Linked Immunosorbent Assay. Result showed a significant increase in FSH and Progesterone level (p<0.05) in treated group when compared with the control group while no significant difference (p>0.05) was observed for the luteinizing hormone in the treated groups. The work thus showed that the plant could exert a positive effect on female fertility by enhancing levels of female reproductive hormones.

The evidence that natural or synthetic drugs can affect the biodistribution of radiopharmaceuticals (radiobiocomplexes) in setting of nuclear medicine clinic is already known. We studied the effect of Paclitaxel, an anti-neoplastic agent for the treatment of solid tumors, on the biodistribution of Na99mTcO4 in female rats. Paclitaxel (1mg/mL/week) was administered into animals in single dose during 3 weeks, with interval of 1 week among them. The control group received NaCl 0.9% solutions by the same via. One hour after the last dose, it was injected Na99mTcO4 in the animals. The percentage of activity per gram (%ATI/g) and biochemical and hematological determinations were performed. A significant increase were found in alanine aminotransferase, aspartate aminotransferase, glucose and in the %ATI/g of some organs (ovaries, uterus, vagina, breasts, large intestine and liver).These results can be associated, probably, to the capacity of paclitaxel to alter the biodistribution of Na99mTcO4 and the metabolism of glucose and hepatic enzymes.
