Apoptotic Effect

Neurotoxicity is an obvious adverse effect in Patients encountering a complete course of chemotherapy. The present work is conducted to evaluate the neuroprotective effect of Ginkgo biloba (Ginkgo) against the neurotoxicity induced by Cisplatin (Cis) in rats. Forty male Wistar albino rats were arranged into four groups: (1) Control group, rats were given saline; (2) Cis group, rats were injected by Cis 2 mg/kg body weight i.p., twice a week starting on the fifth day for thirty days; (3) Ginkgo group, rats were administered Ginkgo (50 mg/kg orally) daily for thirty days; and (4) Ginkgo+Cis group, rats received Ginkgo (50 mg/kg orally) daily and on the fifth day, rats were injected with Cis (2 mg/Kg body weight i.p.) twice a week for thirty days. Cis significantly increased Gamma glutamyltransferase (GGT) and Acetyl Cholinesterase (CHE) as compared to the control group and also disturbed cerebral oxidative/antioxidant redox. Co-administration of Ginkgo and Cis reversed the adverse effect of Cis on the brain tissue. Moreover, co-administration of Ginkgo and Cis ameliorated Cis induced brain damage by reducing Amyloid precursor protein (APP), amyloid β (Aβ), P2Y12R and P2X7R mRNA expressions and proteins. Furthermore, Ginkgo regulated XIAP/BDNF expressions with a consequent decrease of caspase-3 and DNA fragmentation%. The current results concluded that concurrent treatment with Ginkgo can mitigate neurotoxicity mediated by Cis in experimental animals through exhibiting antioxidant effect by restoring cerebral oxidative/antioxidant redox and anti-apoptotic effect via regulating cerebral APP/Aβ/P2Y12R/P2X7R and XIAP/BDNF signaling pathways.

Aim: To provide information on the interactive influence of Sida acuta and Rauvolfia vomitoria on the hippocampus of albino rats using neurohistological parameter. Methods: Thirty-five (35) female adult albino rats were used for the experiment. They were randomly divided into seven groups of five animals in each group. Group 1: The control group was given feed and water ad libitum for 28 days. Groups 2-7 served as the experimental groups. Group 2: Received 200 mg/kg body weight of Sida acuta leaf extract for 14 days. Group 3: Received 212.5 mg/kg body weight of Rauvolfia vomitoria leaf extract for 14 days. Group 4: Received 200 mg/kg body weight of Sida acuta and 212.5 mg/kg body weight of Rauvolfia vomitoria leaf extract for 14 days. Group 5: Received 200 mg/kg body weight of Sida acuta leaf extract for 14 days, then              212.5 mg/kg body weight of Rauvolfia vomitoria for the remaining 14 days. Group 6: Received             400 mg/kg body weight of Sida acuta leaf extract for 14 days, then 425 mg/kg body weight of Rauvolfia vomitoria for the remaining 14 days. Group 7: Received 600 mg/kg body weight of Sida acuta leaf extract for 14 days, then 850 mg/kg body weight of Rauvolfia vomitoria for the remaining 14 days. Results: Sida acuta at the tested dose of 200 mg/kg body weight induced degeneration of pyramidal cells when compared to the control, Rauvolfia vomitoria at the tested dose of 212.5 kg/mg body weight exhibited neuroprotective effect, co-administration of both Sida acuta at 200 mg/kg body weight and Rauvolfia vomitoria at 212.5 mg/kg body weight and administration of Rauvolfia vomitoria after Sida acuta at increasing doses significantly reverse these changes to near normal when compared to the group that received 200 mg/kg body weight of Sida acuta for 14 days. Conclusion: Rauvolfia vomitoria had the potential of ameliorating the neurodegenerative effect caused by the Sida acuta leaf extract on the pyramidal cells of the hippocampus albino rats.

Purpose: The present study aimed to assess functional and structural benefits of erythropoietin (EPO) when administered subconjunctivally in the retina of glaucomatous rats using electroretinography (ERG) and retinal thickness (RT) measurements. Methods: Glaucoma was experimentally induced in 26 Wistar Hannover albino rats. Animals were divided into 2 groups of 13 animals each: a treated group receiving a unique subconjunctival injection of 1,000 IU of EPO and a control group receiving a saline solution. In each group, 7 animals were used for retinal function evaluation (ERG) and 6 animals were used for retinal structural evaluation (histology). RT was measured, dorsally and ventrally, at 500 μm (RT1) and at 1,500 μm (RT2) from the optic nerve. Results: Retinal function evaluation: for both scotopic and photopic conditions, ERG wave amplitudes increased in the treated group. This increase was statistically significant (p < 0.05) in photopic conditions. Structural evaluation: for both locations RT1 and RT2, the retinas were significantly (p < 0.05) thicker in the treated group. Conclusion: Subconjunctival EPO administration showed beneficial effects both on retinal structure and on retinal function in induced glaucoma in albino rats. This neuroprotective effect should be applied in other animal species.

Predisposing Factor

Postprandial hyperglycemia is a predisposing factor for vascular dysfunction and organ damage.α-glucosidase is a hydrolytic enzyme that increases the glucose absorption rate and subsequently elevates blood glucose levels. Garlic (Allium sativumL.) is a rich source of several phytonutrients, including thiosulfinate (THIO). The aim of this study was to evaluate the ability of THIO, a potent inhibitor of intestinalα-glucosidase, to reduce postprandial blood glucose. Male albino rats were randomly assigned to five different groups (n=10/group). Group 1 served as the control group. Groups 2–5 were injected intraperitoneally with a single dose of streptozotocin (STZ) to induce diabetes. Group 2 comprised untreated diabetic rats. Groups 3 and 4 contained diabetic rats that were given THIO orally (20 mg/kg body weight/day and 40 mg/kg body weight/day, resp.). Group 5 was the positive control having diabetic rats treated orally with acarbose (10 mg/kg body weight/day; positive control). Diabetic rats treated with THIO displayed a significant blood glucose reduction (p<0.001and < 0.01 by analysis of variance, resp.) and a significant elevation in insulin compared with that of untreated rats. THIO is an effective noncompetitive intestinalα-glucosidase inhibitor that promotes hypoglycemic action (p<0.001) in STZ-injected rats. THIO is a promising agent for the management of postprandial hyperglycemia.

Background: Among venomous elapid snakes, cobras have the highest public awareness, as their venom represents a combination of proteins, peptides, and enzymes that have a range of biochemical and pharmacological roles and are also the main constitutes of biological activity and lethal toxicity. Objectives: The study aimed to evaluate the effect of the venom of Egyptian Spitting Cobra, Naja nubiae, on the vascular permeability based on the extravasation of the azo dye Evans blue (EB) into the tissues of the liver and kidneys of animals envenomed with low (¼ LD50; 0.32 mg/kg) and high (½ LD50; 0.65 mg/ kg) doses at three sampling times (30, 120, 360 min) post-injection of the venom. Methods: Fifty-four adult male Albino rats (8 weeks old and 180±2 0 g body weight) were divided into three main groups (n=6). In the control group, rats were subcutaneously (SC) injected with saline solution. Envenomed groups were SC injected, one group with 0.32 mg/kg and the other group with 0.65 mg/kg body weight of crude venom, respectively. Rats were I.V injected with EB dye 20 minutes before SC injection with saline solution as control animals and with Naja nubiae venom as treatment groups. Results: The results illustrated a high significant rate of EB extravasation to hepatic and renal tissues by the colorimetric determination of EB dye concentration. Conclusion: The venom of Naja nubiae can cause increased hepatic and renal vascular permeability which may explain the inflammatory effect induced by this venom.

Background: Ovulation induction with clomiphene citrate in women with infertility has been practiced more than 40% years but in infertile patients this treatment plan proved to be ineffective with multiple complication. Body weight plays an important role modulating reproductive development and functioning. Aim: To observe the effects on body weight of female albino rat after use of clomiphene citrate and letrozole for consecutive 1-4 estrous cycles Method: Eighty four adult female Albino rats were equally divided into three groups for this research. Body weight of each rat was measured before and after the experiment. Vaginal smear cytology of each rat was performed to study different phases of estrous cycle. Control group A was given normal saline orally , In Experimental group B rats were given letrozole (Femara) at dose 5mg/kg orally and in Experimental group C rats were given clomiphene citrate at dose 100ug/kg orally. Results: Significant weight gain is observed in rats taking clomiphene citrate as compared to letrozole Conclusion : Comiphene citrate directly affects the body weight which indirectly reduces the ovulation induction and pregnancy rate. Letrozole is good alternate for ovulation induction and for CC resistant patients. Keywords: Estrous cycle, body weight, citrate and letrozole

Background: The prevalence of myocardial infarction (MI) is increasing day by day in Bangladesh due to socioeconomic transition. Spices and herbs are important source of remedy for various diseases in human. Curcuma longa suggested to be used as an indigenous medicine for the prevention and treatment of cardiovascular disease. Objective: To observe the effect of Curcuma longa in isoproterenol induced myocardial infarction in Wistar albino rats. Methods: This experimental study was carried out in the Department of Physiology, Dhaka Medical College, Dhaka during 2015. Twenty one Wistar albino male rats, weighing 100 to 150 g (initial body weight); aged 85 to 100 days were selected for the study. After acclimatization for 14 days, the rats were divided into BC (Baseline control group), ISP-TC (Isoproterenol treated control group) and CLP-ISPT (Curcuma longa pretreated and isoproterenol treated group). Each group consisted of 7 rats. After experiment, on the 10th day, final body weight was taken, rats were sacrificed and blood samples were collected from the heart. The heart was removed and weighed. Serum creatine kinase-MB (CK-MB) level was estimated by ELISA method and Troponin I (cTnI) level by AxSYM method. The statistical analysis was done by one way ANOVA and Bonferroni test as applicable. Results: In this study, the mean percent (%) change of body weight (p<0.01), mean serum CK-MB (p<0.001) and cTnI (p<0.001) levels were significantly higher but mean heart weight was non significantly higher in ISP-TC in comparison to those of BC. Again, the mean percent (%) change of body weight (p<0.01), mean heart weight (p<0.01), mean serum CK-MB (p<0.01) and cTnI (p<0.001) levels were significantly lower in CLP-ISPT than those of ISP-TC group. Conclusion: From the results, it can be concluded that Curcuma longa may have cardioprotective effect. J Bangladesh Soc Physiol. 2018, December; 13(2): 47-53

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.

Background: Non-alcoholic fatty liver disease (NAFLD) is one of the alarmingly rising clinical problems in the 21st century with no effective drug treatment until now. Taurine is an essential amino acid in humans that proved efficacy as a non-pharmacological therapy in a plethora of diseases; however, its impact on NAFLD remains elusive. The aim of the current study is to evaluate the protective mechanism of taurine in experimental steatohepatitis induced by junk food given as cafeteria-diet (CAF-D) in male albino rats. Methods: Forty adult male albino rats of local strain between 8-10 weeks old, weighing 150 ± 20 g, were divided into four equal groups: Group I (control group), Group II (Taurine group), Group III (CAF-D for 12 weeks) and Group IV (CAF-D +Taurine). CAF-D was given in addition to the standard chow for 12 weeks, where each rat was given one piece of beef burger fried in 15 g of sunflower oil, one teaspoonful of mayonnaise, and one piece of petit pan bread, weighing 60g/ piece. In the serum, liver function tests; ALT, AST, ALP, GGT and the lipid profile; TG, TC, HDL-C added to reduced glutathione (GSH) were assessed colorimetrically, while fibroblast growth factor (FGF)-21, adiponectin & interleukin (IL)-6 via ELISA. The same technique was used for the assays of the hepatic levels of FGF-21, silent information regulator (SIRT1), malondialdehyde (MDA),IL-10, tumor necrosis factor-α (TNF-α) as well as the apoptotic markers; caspase-3 and B-cell lymphoma (Bcl-2). Results: The cafeteria-diet induced steatohepatitis was reflected by significantly increased body and liver weight gain, elevation of liver enzymes; ALT, AST, ALP and GGT added to the dyslipidemic panel, presented as increased TC, TG, LDL-C and decreased HDL-C levels. The steatosis-induced inflammatory milieu, marked by elevated serum levels of FGF-21, IL-6, hepatic TNF-α, as well as reduced IL-10 and adiponectin, was associated with steatosis- induced hepatic oxidative stress, reflected by increased hepatic MDA and decreased GSH levels, along with stimulated caspase-3 and decline in BcL-2 hepatic levels. These pathological disturbances were significantly ameliorated by taurine supplementation and evidenced histopathologically. The cross talk between hepatic FGF-21 and SIRT1 and their association to the induced perturbations are novel findings in this study. Taurine's efficacy in restoration of hepatic structure and function is partially via the increase in SIRT1 and associated reduction of FGF-21. Conclusion: The findings of the current study prove the protective role of taurine in NAFLD via a novel role in the amelioration of FGF-21/ SIRT1 axis, which could be considered a new therapeutic target.

Olanzapine is an antipsychotic drug effective in the treatment of stress-associated psychiatric illnesses, but its effect on the spleen remains unclear. Vitamin C is essential for the optimum function of the immune system. We aim to investigate the effect of Olanzapine on spleen structures and to assess the protective effect of vitamin C. Forty adult male albino rats were divided into four groups: group (I), a control; group (II), rats were given vitamin C at 40 mg/kg body weight; group (III), rats were given Olanzapine at 2 mg/kg body weight; and group (IV), rats were given vitamin C and Olanzapine at the same dose of group (II) and group (III) for one month. The hematoxylin and eosin (H&E) of the olanzapine treated group showed focal areas of cellular depletion and a decrease in the size of the white pulp. The red pulp was expanded and showed marked congestion and dilatation of blood sinusoids. Cluster of differentiation 3 (CD3) was significantly reduced, however both tumor necrosis factor alpha (TNF-α), and vascular endothelial growth factor (VEGF) were significantly higher. The administration of vitamin C repaired structural and immunohistochemical changes via increased CD3 and decreased TNF-α and VEGF. Therefore, the oxidative and the inflammatory pathways may be the possible mechanisms underlying olanzapine immunotoxicity. Vitamin C exerted immune modulator and antioxidant effects against olanzapine.
