Bisphenol-A (BPA) and its analog are extensively utilized in the production of plastics which are rather ubiquitous in our environment. At high temperatures, BPA is leached into water and food packed in plastic containers. This research investigated the ameliorative effects of CMSO on adipokines dysfunction and dyslipidemia in male Wistar rats exposed to Bisphenol-A. thirty-six (36) albino rats weighing 100 - 200 g were randomly assigned into six (6) different experimental groups of controls (1, 2, and 3) and the tests (4, 5, and 6). Group 1 was given only 1 ml of olive oil, group 2 received 100 mg/Kg body weight (b.w) of BPA, group 3 was given 7.5 ml/Kg b.w of CMSO, groups 4, 5, and 6 received 100 mg/Kg b.w of BPA and 7.5, 5 and 2.5 mg/Kg b.w of CMSO respectively. CMSO and BPA were concurrently administered via oral intubation for periods of 42 days. Lipid profile and adipokines levels were determined in plasma and adipose tissue. BPA in male rats significantly (p<0.05) elevated the levels of cholesterol, triglycerides, LDL-C, liptin, and coronary and atherogenic risk indices in plasma and adipose tissue with reductions in HDL-C and adiponectin levels. BPA plus CMSO in male rats significantly (p<0.05) decreased the levels of cholesterol, triglycerides, LDL-C, liptin, and coronary and atherogenic risk indices with an elevation of HDL-C and adiponectin levels in both plasma and adipose tissue. These results suggest that CMSO could be useful in the management of cardiovascular-related diseases induced by BPA.

OBJECTIVE: This study evaluated the use of plasma, bone surface (periosteal) and whole bone as biomarkers of chronic fluoride (F) exposure. METHODS: Forty male Wistar rats were assigned to 4 groups (n=10/gr) that differed according to the F concentration they received in the drinking water. Groups 1, 2, 3 and 4 received water containing 0 (control), 5, 15, and 50 mg F/L, respectively. The rats were killed at 120 days of age. Plasma and femur were collected and analyzed for fluoride with the ion specific electrode by the direct method or after hexamethyldisiloxane-facilitated diffusion. Data were tested for statistically significant differences by ANOVA and linear regression (p<0.05). RESULTS: Mean (± SE) plasma F concentrations ranged from 0.030 ± 0.002 to 0.187 ± 0.013 (mg/mL). The concentrations in surface and whole bone ranged from 610 ± 32 to 4,693 222; and 647 ± 22 to 3,439 ± 134 µg/g, respectively. The surface/whole F concentration ratios were 0.941, 1.414, 1.173 and 1.377, for groups 1, 2, 3 and 4 respectively. For plasma and whole bone, the difference among all groups was statistically significant, except for group 2 compared to group 1. For bone surface, all groups differed from each other except for group 2 compared to group 3. A significant positive correlation was found between bone surface and whole bone F (r²=0.94), as well as between plasma and bone surface (r²=0.71) and plasma and whole bone (r²=0.74). CONCLUSIONS: Data suggest that both bone surface and whole bone are suitable biomarkers of chronic F exposure in rats and plasma may be used as indicator of bone fluoride levels.

The majority of liver-related illnesses are caused by occupational and domestic exposure to toxic chemicals like formaldehyde (FA), which is widely common in Africa and the world at large. Hence, measures should be taken to protect humans from its hazardous effects. This study, therefore, examines the protective potential of Ganoderma lucidum (100 mg/kg body weight) on formaldehyde-induced (40%) liver oxido-inflammation in male rats. Male Wistar rats, 150–200 g, were allotted into four groups of 10 animals as follows: Group 1 was orally treated with 1 mg/mL distilled water, Group 2 was exposed to a 40% formaldehyde vapor environment for 30 min per day, Group 3 was orally treated with 100 mg/kg ethanol extract of Ganoderma lucidum, and Group 4 was co-administered formaldehyde and 100 mg/kg ethanol extract of Ganoderma lucidum. Rats were then sacrificed 24 h after administering the last dose of treatment, and the livers were excised. Ganoderma lucidum significantly reversed the formaldehyde-mediated reduction in body and organ weight. Ganoderma lucidum administration significantly prevented oxido-inflammation by reducing the levels of hydrogen peroxide and malondialdehyde and increasing the activity of antioxidant enzymes and glutathione contents, as well as the normal level of nitrite and myeloperoxidase production in FA-treated rats. Additionally, Ganoderma lucidum reversed a large decline in proinflammatory markers in formaldehyde. Furthermore, Ganoderma lucidum restores formaldehyde-induced histological alterations in the liver. Collectively, our results provide valuable information on the protective potential of Ganoderma lucidum in protecting formaldehyde-induced liver oxido-inflammation in male rats.

Ruellia tuberosa L. is a therapeutic plant that is generally consumed in Indonesian traditional medicine to prevent or cure various illnesses, i.e., diabetes. The current study was conducted to investigate the effects of hydroethanolic root extracts of Ruellia tuberosa L. on the kidney of streptozotocin-induced diabetic Wistar rats. In this study, male Wistar rats were divided into 5 groups: healthy rats (group 1), diabetic rats (group 2), and treated rats which received extract at dosages of 250 (group 3), 375 (group 4), and 500 (group 5) mg/kg body weight for 21 days. Diabetes mellitus was experimentally induced by the administration of five doses of streptozotocin 20 mg/kg body weight within five consecutive days. Significant increases in the value of TNF alpha expression and malondialdehyde (MDA) levels were observed in streptozotocin-induced diabetes rats. Furthermore, severe histological alterations of kidney tissues occurred in the diabetic rats group. After treatment was applied, the value of TNF alpha expression and MDA levels on the kidney decreased considerably p < 0.05 in groups 3, 4, and 5. The optimum dosage was obtained at a dose of 250 mg/kg body weight (group 3), which had 42.24% and 52.70% decrease in TNF alpha expression and MDA levels, respectively. The histopathological profiles of the kidney also showed significant improvements in treated groups. The most prominent recoveries were also shown in group 3. The treatments induced repairment in the glomerular and renal tubular damages in the kidney tissues. To conclude, these results emphasize potentially health valuable properties of hydroethanolic root extracts of R. tuberosa L. in rats with streptozotocin-induced diabetes.

Citrullus lanatus thumb (Cucurbitaceae) commonly called watermelon is widely consumed in this part of the world as food and medicine. This study was carried out to examine the effect of methanolic extract of watermelon (Citrullus lanatus) rind on prednisolone suppressed immunity in male wistar rats. A total of 20 male wistar rats weighing 150-294g were used in 4 groups with five rats each. Group 1, the control group was given distilled water and feed, Group 2 was given 200 mg/kg body weight of methanolic extract of watermelon rind, Group 3 rats were given 2.5 mg/kg body weight of prednisolone and Group 4 rats were given 2.5 mg/kg body weight of prednisolone and 200 mg/kg body weight of methanolic extract of watermelon rind. Prednisolone and the methanolic extract of watermelon rind were administered orally for a period of 30 days. Blood samples were collected by cardio puncture from the rats for white blood cell (WBC), lymphocyte, and granulocyte and monocyte counts at the end of the experiment.  The data were statistically analysed using one-way ANOVA (Analysis of variance). Data were considered significant at p<0.05. The results obtained showed that methanolic extract of watermelon rind caused a significant increasen in immune function of rats when compared with the control and immune suppressed rats.

In the present investigation it was aimed to evaluate any possible pharmacokinetic interactions between Phenytoin and Rivaroxaban. Study was conducted in Male Wistar rats; animals were divided into three groups. Group 1 received Phenytoin alone, Group 2 received Rivaroxaban alone and Group 3 received Phenytoin and Rivaroxaban concomitantly. The treatment was given for 8 days and the blood samples were collected on day 1 and day 8. The samples were analyzed by HPLC. The results were showed no significant difference in the Pharmacokinetic parameters of Phenytoin in presence of Rivaroxaban. Whereas Rivaroxaban showed significant decrease in both Cmax and tmax in combination with Phenytoin. Phenytoin is a combined-gp inducer and strong CYP3A4 inducer therefore it may induce the metabolism of Rivaroxaban so it reduces the concentrations and increase the elimination rate. Based on the results obtained from pharmacokinetic study it was evident that the single dose of Rivaroxaban in combination with Phenytoin shows statistically significant interactions in its pharmacokinetic parameters.

Pregabalin (Lyrica) is an analog of the gamma-aminobutyric acid neurotransmitter,   approved for the treatment of epilepsy, generalized anxiety disorder, neuropathic pain, and fibromyalgia. The possibility for abuse and/or dependence on pregabalin has risen recently. Pregabalin is controlled in many countries including Saudi Arabia. However, unofficial use of this substance is also on the increase. The purpose of this study is to assess the potential neurotoxic effects associated with overdose prolonged pregabalin supplementation. Forty male Wistar rats were divided into Group (1) normal control received distilled water, Group (2) received pregabalin (150mg/kg), Group (3) received pregabalin (300 mg/kg), and Group (4) received pregabalin (600 mg/kg). pregabalin consumption in different doses resulted in significant dysregulation in neurotransmitter release, upsurge oxidative stress markers via enhancing lipid peroxidation and depleting antioxidant markers. Also, pregabalin doses evoked brain tissue inflammation through elevating TNF-α, IL-1β, and MCP-1, Moreover promoted brain tissue apoptosis by activating caspase -3 and suppressed Bcl2. Pregabalin effects on the aforementioned parameters were dose-dependent. These findings could highlight the potential neurotoxic effect of prolonged abuse of pregabalin supplementation through dysregulating brain neurochemical, inflammatory, oxidant/antioxidant, and apoptotic mediators.

AbstractObjectives. Bisphenol A (BPA) has been reported that among other male reproductive dys-functions, it can cause marked estrogenic effects including alteration in serum hormones as well as testicular lesions in exposed animals. This work sought to study the role of gallic acid (GA), a known antioxidant, on the BPA-induced testicular oxidative stress in adult male Wistar rats using serum hormone analysis, histopathology, and biochemical assays.Methods. Adult male rats were divided into four groups (n=10) including control (0.2 ml of corn oil), GA (20 mg/kg/day), BPA (10 mg/kg/day), BPA+GA (BPA, 10 mg/kg/day + GA, 20 mg/kg/day). All medications were given by oral gavage for 45 consecutive days. The body and testicular weights were measured. Blood and organ samples were collected for the serum hormonal assay: testosterone (T), luteinizing hormone (LH), follicle stimulating hormone (FSH) and prolactin (PRL), and tissue biochemistry analysis: superoxide dismutase (SOD), reduced glutathione (GSH), glutathione-S-transferase (GST), malondialdehyde (MDA), hydrogen peroxide (H2O2), respectively.Results. The BPA-treated rats showed significant reduction in the gonadosomatic index. BPA also caused significant decrease in the levels of the serum testosterone and prolactin. Furthermore, BPA induced testicular oxidative stress by decreasing the activities of antioxidant enzymes and increasing reactive oxygen species. However, co-treatment with GA protected against these alterations.Conclusion. Findings from the present study confirmed the previously reported data and show that the ability of GA, as a potent antioxidant, may protect against BPA-induced alterations in the male reproductive function. Hence, GA protects against testicular oxidative stress in adult male Wistar rats following chronic exposure to BPA.

The sudden rise in benign prostatic hyperplasia (BPH) cases, severe side effects, and the high cost of conventional methods have necessitated the intensive search for alternative BPH management strategies. This study investigated the restorative effects of ethanol leaf extract of Chromolaena odorata (EECO) on testosterone-induced BPH in male albino rats. Thirty male albino rats with a weight range of 150-210 g were randomly distributed into six groups of five rats each. Group 1 was normal rats and not induced. Groups 2-6 were induced via daily subcutaneous injection of testosterone propionate (3 mg/kg) for 28 days. After induction, group 2 received vehicle (carboxyl methylcellulose), group 3 received finasteride (1 mg/kg), while groups 4-6 received 100, 200, and 400 mg/kg of EECO, respectively, for 21 days orally. Prostate and biochemical parameters were determined using standard methods. Treatments with EECO decreased the concentrations of prostate-sensitive antigen, dihydrotestosterone, testosterone, malondialdehyde, cholesterol, low-density cholesterol, and liver enzyme activities compared with BPH-control. Furthermore, there was increased superoxide dismutase, and catalase activities in extract treated groups compared with BPH- control. The findings from this study showed that EECO inhibited testosterone-induced BPH anomalies, making it promising phytotherapy for the management of BPH in males.

Echis ocellatus snakebite causes more fatalities than all other African snake species combined. Moringa oleifera reportedly possesses an antivenom property. Therefore, we evaluated the effectiveness of M. oleifera ethanol extract (MOE) against E. ocellatus venom (EOV) toxicities. Thirty male rats were grouped as follows (n = 5): Group 1 (normal control received saline), groups 2 to 6 were administered intraperitoneally, 0.22 mg/kg (LD50) of EOV. Group 2 was left untreated while group 3 to 6 were treated post-envenoming with 0.2 mL of polyvalent antivenom, 200, 400, and 600 mg/kg of MOE respectively. MOE significantly (p<0.05) normalized the altered haematological indices and blood electrolytes profiles. MOE attenuated venom-induced cellular dysfunctions, characterized by a significant increase in NRF2, and concomitant downregulation of increased antioxidant enzymes (SOD and CAT) activities in the serum and heart of the treated rats. MOE normalized the elevated TNF-α and IL-1β in serum and heart tissues. Furthermore, the IgG titre value was significantly (p<0.5) higher in the envenomed untreated group compared to the MOE-treated groups. Hemorrhagic, hemolytic and coagulant activities of the venom were strongly inhibited by the MOE dose, dependently. Lesions noticed on tissues of vital organs of untreated rats were abolished by MOE. Our findings substantiate the effectiveness of MOE as a potential remedy against EOV toxicities.

Abstract Background: Pregabalin (PGB) used as analgesic in treatment of neurogenic pains of chronic diseases, is considered as one of the most abused anti-epileptic drugs worldwide and it has been proved that it induces addictive behaviors. The present histopathological study aimed to identify the effect of PGB administration on cerebral cortex and cerebellar cortex, in both acute and chronic toxicity. Seventy-two male and non-pregnant female adult albino rats’ 6- to 8-week-old divided into 3 main groups of 24 rats each were studied. Group 1 represented the control group and group 2 represented the acute toxicity group, in which rats were given a single dose of PGB (5000 mg/kg) orally by gavage and after 24 hours, rats were sacrificed and examined. Group 3 represented the chronic toxicity group; were given PGB 500 mg/kg orally by gavage for 12 weeks, after which rats were sacrificed and examined. Result: Cerebral cortex tissue of acute toxicity group displayed astrocytosis and dystrophic changes, while in chronic group showed degeneration, necrosis and cellular infiltrates. The cerebellum of chronic groups showed degeneration and shrunken of Purkinje cells. Conclusion: Acute and chronic intoxication with pregabalin adversely altered the structure of cerebral cortex and cerebellum.
