Abstract Objectives Reproduction is one of the physiological functions that are often negatively affected by chronic stress. We aimed to examine effects of two distinct 7-day chronic immobilization stress (IMO) models on gonadotropins levels and depression-like behaviors in female rats. Methods Adult Wistar albino female rats were divided into three groups as follows (n=7 for each group): control, IMO-1 (45 min daily for 7-day) and IMO-2 (45 min twice a day for 7-day). Neuropsychiatric behaviors were determined by using forced swimming test (FST) and open field test (OFT). Gonadotropins were analyzed using ELISA tests. Results In FST, swimming was lower, and immobility was higher in the IMO-1 group and IMO--2 group. Climbing score of the IMO-2 group was higher compared to the control group. In OFT, there was no significant alteration in the mean velocity, total distance, duration of time spent in the central area and duration of latency in the central area between the stress groups and the control group. Final body weight and percentage of body weight change were lower in both stress groups. The follicle-stimulating hormone level was lower only in the IMO-2 group, and the luteinizing hormone concentrations were significantly lower in the IMO-1 group and IMO-2 group. Conclusions Our results indicated that depression-like behaviors increased, and gonadotropins decreased in the female rats exposed to 7-day chronic IMO.

Abstract. Alterations of essential elements in the brain are associated with the pathophysiology of many neuropsychiatric disorders. It is known that chronic/overwhelming stress may cause some anxiety and/or depression. We aimed to investigate the effects of two different chronic immobilization stress protocols on anxiety-related behaviors and brain minerals. Adult male Wistar rats were divided into 3 groups as follows ( n = 10/group): control, immobilization stress-1 (45 minutes daily for 7-day) and immobilization stress-2 (45 minutes twice a day for 7-day). Stress-related behaviors were evaluated by open field test and forced swimming test. In the immobilization stress-1 and immobilization stress-2 groups, percentage of time spent in the central area (6.38 ± 0.41% and 6.28 ± 1.03% respectively, p < 0.05) and rearing frequency (2.75 ± 0.41 and 3.85 ± 0.46, p < 0.01 and p < 0.05, respectively) were lower, latency to center area (49.11 ± 5.87 s and 44.92 ± 8.04 s, p < 0.01 and p < 0.01, respectively), were higher than the control group (8.65 ± 0.49%, 5.37 ± 0.44 and 15.3 ± 3.32 s, respectively). In the immobilization stress-1 group, zinc (12.65 ± 0.1 ppm, p < 0.001), magnesium (170.4 ± 1.7 ppm, p < 0.005) and phosphate (2.76 ± 0.1 ppm, p < 0.05) levels were lower than the control group (13.87 ± 0.16 ppm, 179.31 ± 1.87 ppm and 3.11 ± 0.06 ppm, respectively). In the immobilization stress-2 group, magnesium (171.56 ± 1.87 ppm, p < 0.05), phosphate (2.44 ± 0.07 ppm, p < 0.001) levels were lower, and manganese (373.68 ± 5.76 ppb, p < 0.001) and copper (2.79 ± 0.15 ppm, p < 0.05) levels were higher than the control group (179.31 ± 1.87 ppm, 3.11 ± 0.06 ppm, 327.25 ± 8.35 ppb and 2.45 ± 0.05 ppm, respectively). Our results indicated that 7-day chronic immobilization stress increased anxiety-related behaviors in both stress groups. Zinc, magnesium, phosphate, copper and manganese levels were affected in the brain.

Cardiovascular diseases (CVDs) emerging as a major health problem in Bangladesh due to increase prevalence of risk factors. Conventional cardioprotective drugs are effective but expensive and associated with a number of side effects. Curcuma longa is an important source of traditional medicine for the prevention and treatment of CVDs. The objective of the study was to evaluate the protective effect of Curcuma longa on isoproterenol induced myocardial injury in rats. This experimental study was carried out in the Department of Physiology, Dhaka Medical College, Dhaka during 2015. Total 21 Wistar albino male rats, aged 85 to 100 days, weighing 100 to 150 g (initial body weight) were selected for the study. After acclimatization for 14 days, the rats were divided into three groups. Group A (base line control group), Group B (isoproterenol treated control group) and Group C (Curcuma longa pretreated and isoproterenol treated group). Each group consisted of 7 rats. On the 10th day of experiment, rats were sacrificed after taking final body weight. Blood samples were collected from the heart. Serum aspartate aminotransferase (AST) level was estimated by Colorimetric method and lactate dehydrogenase (LDH) level was estimated by ELISA method. The statistical analysis was done by one way ANOVA and Bonferroni test as applicable.  In this study, the mean initial and final body weight of the rats were almost similar and showed no statistically significant difference among the groups. The mean serum AST and LDH levels were significantly (P<0.001) higher in Group B than those of Group A. Again, these levels were significantly (P<0.001) lower in Group C than those of Group B group. From the results, it can be concluded that Curcuma longa has cardioprotective activity on isoproterenol induced myocardial injury in Wistar albino rats. Bangladesh Med J. 2018 Jan; 47 (3): 13-17

Background and Objectives: Nephrotoxicity is one of the limiting factors for using doxorubicin as an anticancer chemotherapeutic. Reactive oxygen species and cytokines have been implicated in the nephrotoxicity induced by doxorubicin. The main objective of the present study is to identify and compare the histomorphological features in kidneys of albino rats and gross morphological features such as weight of rats and weight of the kidneys due to administration of doxorubicin. Materials and Methods: In the study, albino rats were taken as the animal model. Sixty animals were taken as the sample size. They were divided into two equal groups: experimental (n=30) and control (n=30). Rats of experimental group were treated with anticancer drug doxorubicin at a single intraperitoneal dose of 10 mg/kg body weight while the Control group of rats received a similar volume of 0.9% normal saline. The ethical clearance was taken prior to the research from IERB committee BPKIHS Dharan.  Results: Our results showed that there was high effect of drug in experimental groups of rats. It was seen that there was significant decrease in the body weight and weight of kidneys. The final body weight and kidney weight between experimental and control group showed the significant difference. Similarly there were no significant differences in the normal architecture between the male and female rats. The normal renal histological features were seen on the kidneys in the control group whereas the rats intervened with the drug had some disrupted histological features which reveal the toxicity of the drugs in the kidneys. Conclusion: The study showed toxicity of the drug in the kidneys of experimental groups of rats irrespective of gender and suggest that doxorubicin causes significant loss of the body weight and weight of kidneys and causes the disruption in the normal histological features.

The purpose of the present study was to determine the effects of polysaccharide from Rhodiolae Radix (PRR) on physical fatigue using a forced swimming test in male mice. 96 mice were divided randomly into four groups based on body weight (n = 24). One of the groups was the control group; the others were PRR supplemented groups (25, 50 and 100 mg/kg body weight). Forced swimming test of mice were carried out after 28 days of PRR administration, and the blood lactic acid (BLA), blood urea nitrogen (BUN), liver glycogen and muscle glycogen contents were determined. The data suggest that PRR can extend the exhaustive swimming time of the mice, as well as increase the tissue glycogen contents, and decrease the BLA and BUN contents. These results indicated that PRR had significant anti-fatigue effects.DOI: http://dx.doi.org/10.3329/icpj.v2i3.13579 International Current Pharmaceutical Journal, February 2013, 2(3): 49-52

Background: Cardiotoxicity can be developed due to prolonged use of higher doses of some drugs, exposure to some chemicals, toxins or infectious agents and also by some disease conditions. Natural plant food such as peanut (Arachis hypogaea L.) may have free radical scavenging and lipid lowering activity, thereby, can be used for the prevention and management of heart disease. Objective: To observe the protective effect of peanut (Arachis hypogaea L) and its combined action with propranolol on dyslipidemia in Isoproterenol induced cardiotoxic rats. Methods: This experimental study was carried out in the Department of Physiology, Sir Salimullah Medical College (SSMC), Dhaka from January to December, 2012. Twenty Wistar albino rats, age 85-100 days, weighing 120 to 150g (initial body weight) were included in the experimental group (Group B, with peanut). They were further sub-divided into group B1 (isoproterenol treated group after peanut treatment), and group B2 (isoproterenol treated group after combined treatment of peanut and propranolol). Age and weight matched 30 Wistar albino rats without any peanut supplementation was taken as control (group A) and divided into three sub-groups, group A1 (baseline control), group A2 (isoproterenol treated control) and group A3 (isoproterenol treated control after propranolol treatment). Each subgroup consisted of 10 rats. After taking final body weight all the rats were sacrificed on 22nd day. Blood was collected from heart and supernatant serum was preserved in deep freeze until analysis. For assessment of lipid profile status, serum total cholesterol (TC), low density lipoprotein cholesterol (LDL- C) and high density lipoprotein cholesterol (HDL-C) were estimated by standard method. The statistical analysis was done by one way ANOVA and Bonferroni test as applicable. Results: In this study, percent change from initial body weight to final body weight was significantly (p<0.01) lower both in isoproterenol treated group after peanut treatment and in isoproterenol treated group after combined treatment of peanut and propranolol as compared to that of baseline control. Again, this value was almost similar and the difference was not statistically significant between isoproterenol treated group after peanut treatment and isoproterenol treated group after combined treatment of peanut and propranolol. Again, the mean serum TC (p<0.01) and LDL-C (p<0.05) were significantly lower in isoproterenol treated group after peanut treatment and isoproterenol treated group after combined treatment of peanut and propranolol in comparison to those of isoproterenol treated control group. Moreover, the mean serum HDL-C was significantly (p<0.01) higher in isoproterenol treated group after combined treatment of peanut and propranolol, in comparison to that of isoproterenol treated control group. Furthermore, the mean serum TC and LDL-C were non significantly higher and serum HDL-C was significantly (p<0.01) higher in isoproterenol treated group after combined treatment of peanut and propranolol when compared to those of isoproterenol treated group after peanut treatment. Conclusion: The present study revealed that peanut alone can maintain blood lipid level by decreasing TC and LDL-C levels and by increasing HDL-C level in isoproterenol induced cardiotoxic rats. However, the combined therapy of peanut with propranolol showed synergistic effect on preventing dyslipidemia.

This study was initiated on 24 prepubertal Holstein x Kankrej crossbred heifers of nearly identical age (7-9 months) and body weight (130-140 kg) at University farm to evaluate the effect of high plane of nutrition on blood biochemical and minerals profile and the age at puberty. Twelve heifers were managed under routine farm feeding (control) and the rest 12 under ideal optimum feeding regime (treatment) that included extra 1 kg concentrate, 30 g min mix and ad-lib dry fodder. The body weight and ovarian ultrasonography together with blood sampling was carried out at monthly interval from 10 to 18 months of age to study the ovarian dynamics and blood biochemical changes. High plane of nutrition to growing heifers was beneficial in reducing the age of onset of puberty (by 2-3 months) compared to routine farm fed group. The mean plasma total protein and cholesterol concentrations showed a rising trend with significant variations from 10 to 16 months of age, where it got mostly stabilized indicating adult profile. The activity of enzymes GOT and GPT also rose gradually and significantly from 10 months till 14-15 months of age, and thereafter it remained more or less static till 18 months of age. The levels of both these enzymes were higher, with lower protein and cholesterol, in control than the treatment group from 15-16 months of age onwards. The mean plasma levels of both calcium and phosphorus increased gradually and significantly with advancing age till 16-17 months of age, with little higher values in supplemented than a control group. The plasma levels of zinc, iron, copper, and cobalt also showed rising trend with significant differences between 10th and 12th-14th months of age, and from 15th to 18th months of age the levels were statistically the same in all the groups with slightly higher values in the treatment group.

Orlistat (Ols), a potent inhibitor of pancreatic lipase, was added to the fat source (1 or 4 mg Ols/g fat) of a macronutrient self-selection diet fed to adult female rats. The rats responded to the drug-induced reduction in fat absorption by decreasing their dietary fat intake and increasing their protein and carbohydrate intake in a dose-related manner. Total caloric intake also increased, but body weight gain was inhibited compared with the nondrug control group. When Ols was removed from the diet, nutrient selection, caloric intake, and body weight returned to control levels. In additional short-term experiments (30 min/day), rats developed a preference for a plain fat diet over an Ols-fat diet (4 mg/g fat) and also for a cue flavor paired with plain fat over a flavor paired with Ols-fat. Yet, when not given the choice, the rats consumed nearly as much Ols-fat as plain fat diet. These results indicate that, by reducing fat absorption, Ols reduced the attractiveness of dietary fat, although it did not make the fat diet aversive. In clinical use, lipase inhibitors may be effective in reducing dietary fat intake by reducing both the consumption and absorption of fat.

<p class="Abstract">The aim of this study was to evaluate the diuretic activity of <em>Eysenhardtia polystachya</em> bark aqueous extract at different doses in a rat model. Different doses of <em>E. polystachya</em> (125, 250, 500 and 750 mg/kg body weight), furosemide (4 mg/kg) and vehicle were administered per os to female rats (n=6 animals per group). After 6 hours in metabolic cages, the effect on urinary flow, glomerular filtration rate and electrolyte balance of sodium and potassium were assessed in all animals. <em>E. polystachya</em> at the doses of 500 and 750 mg/kg induced diuretic activity, since markedly increased (p&lt;0.05) the urinary flow rate, similar to that of furosemide treated group. Only the dose of 750 mg/kg produced an increment in urinary excretion of sodium but not of potassium compared with control group. These findings indicate that<em> E. polystachya</em> bark-induced diuretic activity, providing evidence for its folkloric use.</p><p> </p>

The research was conducted on the effect of bird broilers fed with different hybrid rye doses on the fatty acids profile in muscle. The first experiment was performed on 3 geese broilers groups fed with hybrid rye, oats or hybrid rye and oats mix in proportion 1:1. No effect of the hybrid rye feeding of geese on the SFA level in meat was observed, but the MUFA level was significantly higher and PUFA level and n-6/n-3 PUFA ratio were significantly lower than in geese fed with oats. The second experiment was performed on 3 chicken broiler groups fed with mix of corn, wheat, soybean meal and rapeseed oil (control group), and fed with an addition of 10% or 20% hybrid rye in diet (experimental groups). No effect of hybrid rye feeding of chicken broilers on the meat quality and SFA level was observed. However, the MUFA level was higher and the PUFA level and n-6/n-3 PUFA ratio were lower in meat of chicken broilers fed with hybrid rye. In conclusion hybrid rye is a healthy ingredient in the diet of studied birds and may be used up to 20% in chicken broilers and 50% in the diets of geese. A 100% hybrid rye in geese diet caused lower final body weight.

Jawarish Shahi (JS) is a compound polyherbal Unani pharmacopoeial formulation indicated for Khafqan (Palpitation), Nafkh-e-Shikam (Flatulence) and Waswas (Insanity; false perception and hallucinations). Jawarish Shahi contains herbs like Halela (Terminalia chebula), Amla (Emblica officinalis), Kishneez (Coriandrum sativum), Elaichi Khurd, (Elettaria cardamomum), and Bed Mushk (Salix caprea). The present study was carried out as per OECD 408 guidance to evaluate 90 days repeated oral dose toxicity in male and female Sprague Dawley rats. The study was performed at dose levels 1028 and 2000 mg/kg bw. No adverse effects were reported with respect to body weight, feed intake, behavior and clinical signs indicative of systemic toxicity. The expected growth pattern was observed in body weight and feed intake as compared to control group at both dose levels in male and female rats. There were few significant alterations with respect to hematology, and clinical biochemistry, however the results were within normal range thus considered toxicologically insignificant. The microscopic examination of different organ/tissue showed that no histopathological changes were observed. The findings of the study showed that No Observed Adverse Effect Level (NOAEL) for JS is greater than 2000 mg/kg body weight
