Abstract PurposeThis study aims to investigate the effect of electromagnetic field (EMF) exposure which is environmental toxic agent on rat ovary. MethodsA total of 30 female Wistar albino rats are randomly divided into three groups (n=10) as Control, Sham, and EMF groups. The rats are not exposed any processes in Control group. The rats are kept in special cage for the same duration as in the EMF group without any EMF exposure in Sham group while the rats are exposed to 900 MHz EMF with a special mechanism in EMF group. At the end of day 28, the ovarian tissues are collected. Stereological and biochemical examinations are performed.ResultsConcerning the GSI values, there are statistical differences between the Control and EMF (p=0.001), and Sham and EMF (p=0.001) groups, respectively. There are also statistical differences between Control and EMF groups in terms of volumetric parameters including medullary, and follicular antral volumes. Regarding the biochemical parameters, there are statistically differences between the Control and EMF (p=0.000), and Sham and EMF (p=0.000) groups, respectively.ConclusionIt may be concluded that exposure to a 900-MHz EMF leads to changes in ovarian follicle volumes which may affect the ovarian reservoir.

Adipose tissue is an endocrine organ and has central role in interaction with other organs or tissues while propolis can induce lipolysis. Therefore, the aim of this study is to provide detailed information about adipose tissue homeostasis modifications and body composition during propolis supplement consumption. Twenty male Wistar albino rats (8 weeks) were divided into two groups of 10 animals each and fed for 90 days with two different types of diets: standard for the control group (diet C) and standard diet + 2% propolis (diet P). Thyroid hormones did not show differences, while ghrelin and adiponectin decreased in the group that was fed propolis. Insulin, leptin, and non-esterified fatty acids also increased along with reduced body weight and fat, in addition to increased lean mass when propolis was in the diet. We conclude that propolis could decrease ghrelin and adiponectin but increase non-esterified fatty acids and insulin secretion, which improves body composition.

Lipid lowering effect of polyherbal formulations using eight different plants was evaluated in triton and diet induced hyperlipidemic models of wistar albino rats. Formulations such as Tablet, Syrup and Suspension inhibited the elevation in serum cholesterol and triglyceride levels on Triton WR 1339 administration rats. The formulations at the same dose level significantly attenuated the elevated serum total cholesterol and triglycerides with an increase in high-density lipoprotein cholesterol in high-fat diet-induced hyperlipidemic rats. The standard drug Niacin showed slightly better effects. The treatment with herbal formulations produced 30-35 percentage improvement in oral glucose tolerance. Similarly all the formulations also reduced the elevated C-reactive protein which is a marker of Hyperlipidemia. In histopathological study it was found that treatment of polyherbal formulation significantly reduced the plaque size in aorta compared with HFD treated control group. The outcome of the study reveals the lipid lowering activity of polyherbal formulations in dyslipidaemic conditions by interfering with the biosynthesis of cholesterol and utilization of lipids.

Aim: In cyclosporin-A (CsA)-induced toxicity, oxidative stress has been implicated as a potential responsible mechanism. Therefore, we aimed to investigate the protective role of erdosteine against CsA-induced nephrotoxicity in terms of tissue oxidant/antioxidant parameters and light microscopy in rats. Materials and methods: Wistar albino rats were randomly separated into four groups. Group 1 rats treated with sodium chloride served as the control, group 2 rats were treated with CsA, group 3 with CsA plus erdosteine, and group 4 with erdosteine alone. Animals were killed and blood samples were analyzed for blood urea nitrogen (BUN), serum creatinine (Cr), uric acid (UA), total protein (TP), and albumin (ALB) levels. Kidney sections were analyzed for malondialdehyde (MDA) and nitric oxide (NO) levels and superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities, as well as for histopathological changes. Results: In the CsA group, MDA, GSH-Px, BUN, and Cr levels were increased. The TP and ALB levels were decreased. These changes had been improved by erdosteine administration. Other biochemical parameters did not show any significant change. Conclusion: These results indicate that erdosteine produces a protective mechanism against CsA-induced nephrotoxicity and suggest a role of oxidative stress in pathogenesis.

The paper presents research on the electromagnetic hazards related to the flow of electric currents throughout the bodies of employees using portable radios. The values often exceed established limits, which may lead to potential dysfunctions of the body and affect the safety of performed professional duties. The measurements of the electric field (E-field) distribution of a typical commercial portable radio, the limb contact current calculations, and the computer simulations determining a specific absorption rate (SAR) were supplemented with pilot neurophysiological tests. The assessment indicated a large spatial variability of the E-field strength around the devices. The head of the operator and the hand holding the radio were often in the electromagnetic field (EMF), which exceeded the established limits. The calculated SAR values ranged within the permitted limits. The conducted neurophysiological tests showed no effects of EMF exposure in comparison to the control group. The assessment of exposure to the EMF using a portable radio is initially performed by analyzing external measures: both computer simulations and measurements of workers’ limb currents. The SAR values exclude thermal effects; however, they do not eliminate potential neuromuscular effects. More neurophysiological tests are needed to obtain a broader picture of possible health effects.

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

Long-term use of the peritoneum as a dialysis membrane results in progressive irreversible dysfunction, described as peritoneal fibrosis. Oxidative stress during peritoneal dialysis has been established in many studies. Generation of reactive oxygen species (ROS) by conventional peritoneal dialysis solutions, regardless of whether produced by high glucose, angiotensin II, or glucose degradation products may be responsible for progressive membrane dysfunction. The well-known antioxidant molecule N-acetylcysteine (NAC) is capable of direct scavenging of ROS. The aim of the present study was to investigate the effect of NAC therapy on both progression and regression of encapsulating peritoneal sclerosis (EPS). We divided 49 nonuremic Wistar albino rats into four groups: Control group—2 mL isotonic saline intraperitoneally (IP) daily for 3 weeks; CG group—2 mL/200 g 0.1% chlorhexidine gluconate (CG) and 15% ethanol dissolved in saline injected IP daily for a total of 3 weeks; Resting group—CG (weeks 1 – 3), plus peritoneal resting (weeks 4 – 6); NAC-R group—CG (weeks 1 – 3), plus 2 g/L NAC (weeks 4 – 6). At the end of the experiment, all rats underwent a 1-hour peritoneal equilibration test with 25 mL 3.86% PD solution. Dialysate-to-plasma ratio (D/P) urea, dialysate white blood cell count (per cubic milliliter), ultrafiltration (UF) volume, and morphology changes of parietal peritoneum were examined. The CG group progressed to encapsulating peritoneal sclerosis, characterized by loss of UF, increased peritoneal thickness, inflammation, and ultimately, development of fibrosis. Resting produced advantages only in dialysate cell count; with regard to vascularity and dialysate cell count, NAC was more effective than was peritoneal rest. Interestingly, we observed no beneficial effects of NAC on fibrosis. That finding may be a result of our experimental severe peritoneal injury model. However, decreased inflammation and vascularity with NAC therapy were promising results in regard to membrane protection.

The aim of this study was to investigate the antioxidant effects of tempol on ovarian ischemia–reperfusion (I/R) injury in rats. Forty female Wistar albino rats were randomly divided into 5 groups: Group I, sham; Group II, ischemia (I); Group III, I/R; Group IV, I/R + tempol 30 mg/kg i.p; Group V, I/R + tempol 50 mg/kg i.p. Oxidative stress index (OSI) was significantly higher in the ischemia group and the I/R group than in the sham group. Catalase levels were significantly lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. Glutathione peroxidase levels were lower in the I/R group than in the I/R + tempol 30 mg/kg i.p. and the I/R + tempol 50 mg/kg i.p. groups. MDA levels were significantly lower in the I/R + tempol 30 mg/kg i.p. group and the I/R + tempol 50 mg/kg i.p. group than in the I/R group. The levels of the histopathological parameters were significantly decreased in the I/R + tempol 50 mg/kg i.p. group compared with the I/R group. Tempol can be used for reducing ovarian I/R injury.

Abstract Since the early 1940s, a significant amount of research has been conducted to describe the impact of the high-G acceleration on the cardiovascular system. The objective of the present study was to examine the role of the antioxidant enzyme system under biodynamic stress in the liver, heart and gastric mucosa in response to high-magnitude +Gz exposure in a rat model. Twenty adult male Wistar albino rats (10 rats per group; 9-11 weeks old, 200-250 g b.w.) were divided into the following two groups: control and G (exposed to a biodynamic stress model under positive (+7 Gz) acceleration for 40 s). The influence of acute biodynamic stress on pro-oxidative parameters in the rat liver (xanthine oxidase (XOD), catalase (CAT), peroxidase (Px), glutathione peroxidase (GSH-Px), total content of glutathione (GSH), lipid peroxidation (LPx)) and on histopathological alterations in the liver, cardiac muscle and gastric mucosa was examined. Biodynamic stress resulting from positive (+7 Gz) acceleration resulted in a highly statistically signifi cant increase of CAT GSH-Px activity compared to the control group. The LPx levels were significantly decreased, but the GSH contents and the activities of other enzymes were not significantly changed. Significant microscopic changes in the liver, heart and gastric mucosa were observed in the G group. These results clearly indicate that +Gz acceleration alters biochemical systems. These alterations in cellular processes may be mediated by influences of hypoxia or ischaemia via changes in the antioxidant capacity.

Objectives. The present study was aimed at investigating the wound healing effect of ethanolic extract of Cestrum nocturnum (L.) leaves (EECN) using excision and incision wound model. Methods. Wistar albino rats were divided into five groups each consisting of six animals; group I (left untreated) considered as control, group II (ointment base treated) considered as negative control, group III treated with 5% (w/w) povidone iodine ointment (Intadine USP), which served as standard, group IV treated with EECN 2% (w/w) ointment, and group V treated with EECN 5% (w/w) ointment were considered as test groups. All the treatments were given once daily. The wound healing effect was assessed by percentage wound contraction, epithelialization period, and histoarchitecture studies in excision wound model while breaking strength and hydroxyproline content in the incision wound model. Result. Different concentration of EECN (2% and 5% w/w) ointment promoted the wound healing activity significantly in both the models studied. The high rate of wound contraction (P<0.001), decrease in the period for epithelialization (P<0.01), high skin breaking strength (P<0.001), and elevated hydroxyproline content were observed in animal treated with EECN ointments when compared to the control and negative control group of animals. Histopathological studies of the EECN ointments treated groups also revealed the effectiveness in improved wound healing. Conclusions. Ethanolic extract of Cestrum nocturnum (EECN) leaves possesses a concentration dependent wound healing effect.
