Jumping Exercise

This study was performed to determine the effects of 8-week honey supplementation combined with different jumping exercise intensities on serum cortisol, progesterone, estradiol, and reproductive organs. Eighty-four 9-week-old female rats were divided into 7 groups: baseline controls (C0), sedentary group (C), 20 and 80 jumps per day (Ex20J,Ex80J), honey (H), and combined honey with 20 and 80 jumps per day (HEx20J,HEx80J) groups. Jumping exercise was performed at 5 days/week and honey was given at a dosage of 1 g/kg body weight/day for 7 days/week. The level of serum cortisol was higher inEx20JandEx80Jcompared to C. There was significantly lower value of serum cortisol inHEx20Jcompared toEx80J. Serum progesterone levels were significantly lower inEx20JandEx80Jcompared to C. However, serum progesterone levels were significantly higher inHEx20JandHEx80Jcompared toEx20JandEx80J. Relative uterine weights were significantly greater inHEx20Jcompared to C andHEx80J, respectively. There was no significant difference in estradiol level and relative ovarian weights among all the groups. Therefore, honey elicited beneficial effects in reducing the increase of cortisol and in increasing the reduce of progesterone levels induced by different intensities jumping exercise in female rats.

Background We assessed histopathological changes of ovaries and uterus in female rats subjected to different jumping exercise intensities combined with honey supplementation at one g/kg body weight/day. Methods A total of 72 rats were divided into six groups, 12 rats in each: control (C), 20 and 80 jumps (20E, 80E), honey (H), and 20 and 80 jump with honey (20EH, 80EH). Results The endometrium was significantly thicker in the rats in H, 20EH and 80EH groups compared to C, 20E, and 80E. The myometrium thickness was significantly lower in 80E and significantly higher in 80EH compared to C, respectively. There was significantly higher myometrium thickness in 20EH and 80EH compared to 20E and 80E and H. The number of glands of the uterus in 20E and 80E was significantly lower than C. However, there was a significantly higher number of glands in H, 20EH, and 80EH compared to 20E and 80E. The numbers of uterus vessels were significantly lower in 80E compared to 20E. However, the numbers of vessels were significantly higher in H, 20EH, and 80EH compared to 80E. The number of ovarian haemorregia was significantly lower in 20E, 80E, H, 20EH, and 80EH compared to C. The number of corpora lutea was significantly lower in 80EH, H, 80E, and 20E compared to C. However, the number of corpora lutea was significantly higher in 20EH compared to J20 and H. Conclusion This study suggested that jumping exercises in particularly high-intensity exercise may induce histopathological changes in uterus and ovary in rats, and honey supplementation may ameliorate these effects.

Abstract Polycystic ovary syndrome (PCOS) is the commonest endocrinopathy in women of reproductive age, with a prevalence of 5-8%. Long-term complications seen in PCOS include cardiovascular disease and type 2 Diabetes Mellitus. Current therapies do not completely address the cardiometabolic perturbations seen in women with PCOS. Resveratrol (RSV), a natural polyphenol, is shown to have beneficial cardio-metabolic effects in various pathological conditions including that on insulin sensitivity, cardiovascular function. In-vitro studies suggest it’s beneficial effects on ovarian function as well. Therefore, we hypothesized that chronic exposure to RSV would improve both cardiovascular and metabolic phenotypes in PCOS. To test this hypothesis we used an established rat model of PCOS that develops metabolic derangement and irregular cycles. A 7.5 mg (90-day release) dihydrotestosterone (DHT) pellet providing a daily dose of 83 mcg was implanted in 5-week-old female rats. Studies were also conducted on littermate matched controls (C) with no DHT implant. A subgroup of the control and DHT treated rats (n=6 per group) received a 0.84 g/kg dose of resveratrol (RSV) in their chow starting at age 5 weeks. At 8 weeks, animals were weighed weekly (n=6 per group). Oral glucose tolerance test (OGTT n=6 per group) and cardiac echocardiogram (C n=12, C+RSV n=6, DHT n=10, DHT+RSV n=6) were conducted at 16-weeks of age. Body weight increased significantly in DHT treated rats compared to C between 8 and 16 weeks (40 vs 22 grams, p <0.001). RSV treatment did not mitigate the effects of DHT on body weight (34 vs 40 grams, p>0.5). There was significantly higher glucose excursion at 30 minutes post glucose load in both DHT (148± 7.4 mg/dl) and DHT+RSV (139± 7.4 mg/dl) compared to C group (121± 13 mg/dl, p<0.001, p=0.03 respectively). However, by 60 and 90 minutes only DHT group had a significantly higher glucose excursion compared to both DHT+RSV and C groups (131± 4.1,124± 5.7,110 ± 5.9 mg/dl, p=0.015,p=0.21 respectively); 90min (118±5.8,110±4.7,96±4.2 mg/dl, p<0.01,p=0.09 respectively). By 120 minutes, no significant difference in glucose levels existed between groups. Cardiac echocardiogram showed significantly lower mitral valve E/A ratio (and increased MV isovolumic relaxation time (IVRT) in DHT group compared to C. RSV treatment reversed these changes. In conclusion, RSV improved glucose homeostasis and diastolic dysfunction in the DHT induced rodent model of PCOS and may serve as a novel treatment option targeting the cardiometabolic derangement seen in PCOS. Further studies elucidating the mechanisms underlying the beneficial effects of RSV on cardio-metabolic phenotype in this PCOS rodent model is warranted.

The effects of a new experimental drug, KF-868, were investigated after administration to pregnant Sprague-Dawley rats at 0(vehicle), 0.1, 2.0, and 40.0 mg/kg per day during Days 7 through 17 of gestation by examination of term fetuses and naturally delivered offspring. Pregnant rats administered 0.1, 2.0, and 40.0 mg/kg per day gained significantly more weight during the dosage period than did the vehicle control group. Treatment-related physical signs, bloody crust on nose and stains on fur, were observed in the high dosage group. Fetal viability was significantly increased, and resorptions were significantly decreased for the mid and high dosage groups, when compared with the control group. Average fetal body weights for cesarean-delivered fetuses were less for the 40.0 mg/kg per day dosage groups than for the vehicle control group. Visceral and skeletal evaluations of fetuses revealed no difference between the control and test groups. Percent survival of pups was significantly less for the high dosage group than for the control group. Average rat body weights prior to mating for the high dosage group were generally less than for the control group. All physical and functional developmental values were comparable among the control and test groups. Evaluation of postweaning parameters of pups revealed no significant difference in sex maturation, behavior (open-field and water maze), and reproductive capacity. Average body weight gains during the 9-week growth period before mating were significantly less for the 40.0 mg/kg per day dosage group F1 generation female rats. Toxicity in fetuses and offspring was observed only at the highest dosage level. Dosage-dependent, significant increases in maternal body weight gain, as compared with control values, occurred for doses in the 3 KF-868-administered groups. These results indicate that 0.1 and 2.0 mg/kg per day dosages of KF-868 were not lethal and did not produce any adverse effects on the morphological or functional development of offspring. Toxicity was evident in offspring and fetuses of dams administered 40.0 mg/kg per day KF-868, 40,000 times as high as the daily therapeutic dose.

Background: This randomized double blinded study was done to compare the effect of intravenous morphine and fentanyl in attenuation of stress response during surgeries under general anesthesia in adults. The attenuation of stress response was analyzed with changes in serum cortisol and glucose levels one hour after induction of anesthesia. Methods: Fifty consented healthy volunteers in age group 20-50, under ASA I and ASA II posted for elective surgery were included in the study. Two groups of 25 each, group M who received 0.2 mg/kg body weight of morphine and group F who received 2 microgram/kg body weight of fentanyl before anaesthetic induction were compared. The members of two groups were randomly allocated and double blinded using sealed envelope technique. Blood samples were collected for baseline glucose and cortisol in all the subjects. One hour after the administration of study drugs, which was given at the time of induction blood samples were collected for analysis of glucose and cortisol. The changes in blood glucose and serum cortisol levels were compared at the end of the study using independent samples ‘t’ test. Results: There was no significant difference in blood sugar levels in both groups at the end of 1 hour. But there was significant increase in serum cortisol levels in group F compared to group M. Conclusion: This study concludes that morphine is better than fentanyl in attenuation of Intraoperative stress by effectively controlling serum cortisol levels.

AbstractNuts are good sources of dietary fiber, magnesium, polyunsaturated fats, vitamin E, and antioxidants, all of which may have health benefits and associated with increased sensations of satiety and could have beneficial effects on weight control. This study aims to determine the effects of a balanced hypocaloric almond (30 g/day) enriched diet (AED) compared to a balanced hypocaloric almond free diet (AFD) on anthropometric measurements and blood parameters. Study was a 3-months, randomized, controlled trial with four serial measurements on 32 overweight and obese (BMI: ≥ 25 kg/m2) women, aged 25–50 years. The subjects were randomly divided into two groups (16 AED and 16 AFD). Individualized hypocaloric diets of AED considering the energy recommendation, 30 g/day of almonds was added as a snack. Demographic characteristics, nutritional habits, physical activity levels of subjects were determined by a questionnaire. 24-hour dietary intakes for 3 consecutive days (one day week-end) were recorded at the beginning, 1rd, 2nd, and 3rd months of the study. Anthropometric measurements (height, body weight, waist, hip and neck circumferences) were taken and body composition was determined by Bioelectrical Impedance Analysis (BIA), BMI, waist/hip circumference ratio (WHR) and waist circumference/height ratio (WHtR) were calculated. Fasting blood glucose, insulin level, HbA1c, HOMA-IR, total cholesterol, triglycerides, serum iron, haemoglobin, TSH, CRP were determined prior to and at the end (3rd month) of the study. At the beginning of the study no statistically significant difference was found between anthropometric measurements of the groups (p > 0.05). Body weight, BMI, waist, hip circumferences, WHR, WHtR, percentage of body fat, body fat mass were decreased significantly in almond and control groups compared with the beginning and 1rd, 2nd., 3rd months of the study (p = 0.001). Significant reductions in HbA1c and LDL-cholesterol levels were determined in almond group (p < 0.05). Statistically significant differences were found in insulin, HDL-cholesterol, triglycerides and HOMA-IR levels compared to the prior and end of study in both groups (p < 0.05). Balanced hypocaloric diet caused weight loss and improvements in anthropometric and blood parameters in both groups, but better improvement was determined with almond enriched diet. Almonds as a snack could be recommended as a healthy choice in weight reduction diets. Almonds fiber and protein content may have beneficial effects on weight reduction.

The purpose of this study was to investigate the effects of a chronic intracerebroventricular administration of corticotropin-releasing factor (CRF) on energy balance of male and female rats. One week after their delivery to the laboratory, both male and female rats were divided into two groups. One group in each sex was treated with human/rat CRF, while another group was infused with the vehicle. Chronic administration of CRF was accomplished by means of miniosmotic pumps connected to a cannula that was stereotaxically directed into the third ventricle. Food intake and body weight were measured each day during the study. After 14 days of treatment, the rats were killed by decapitation. Energy, fat, and protein contents of the carcasses were quantified. Serum testosterone and estradiol were assayed in males and females, respectively. Administration of CRF significantly reduced body weight gain and food intake in male rats. No significant difference in those variables was observed between female rats treated with CRF and their controls infused with saline. Similarly, metabolizable energy intake and body energy gain were reduced in male rats infused with CRF, whereas no difference was observed between female animals treated with CRF and those infused with saline. In male rats, body fat and body protein contents were lower in CRF-treated than in saline-infused rats. In female rats, CRF did not affect body composition. Serum testosterone in male rats and serum estradiol in female animals were reduced after chronic infusion of CRF.(ABSTRACT TRUNCATED AT 250 WORDS)

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.

This study investigated effects of cessation of exercise and honey supplementation on bone properties in young female rats. Eighty-four 12-week-old Sprague-Dawley female rats were divided into 7 groups: 16S, 16J, 16H, 16JH, 8J8S, 8H8S, and 8JH8S (8 = 8 weeks, 16 = 16 weeks, S = sedentary without honey supplementation, H = honey supplementation, and J = jumping exercise). Jumping exercise consisted of 40 jumps/day for 5 days/week. Honey was given to the rats at a dosage of 1 g/kg body weight/rat/day via force feeding for 7 days/week. Jumping exercise and honey supplementation were terminated for 8 weeks in 8J8S, 8H8S, and 8JH8S groups. After 8 weeks of cessation of exercise and honey supplementation, tibial energy, proximal total bone density, midshaft cortical moment of inertia, and cortical area were significantly higher in 8JH8S as compared to 16S. Continuous sixteen weeks of combined jumping and honey resulted in significant greater tibial maximum force, energy, proximal total bone density, proximal trabecular bone density, midshaft cortical bone density, cortical area, and midshaft cortical moment of inertia in 16JH as compared to 16S. These findings showed that the beneficial effects of 8 weeks of combined exercise and honey supplementation still can be observed after 8 weeks of the cessation and exercise and supplementation.

Aim: Obesity levels dramatically increased in the last decade in UAE. Diets high in energy, saturated fatty acids, low intake of fruits and vegetables as well as inactivity have been found to promote overweight and obesity.  A diet high in fiber has been suggested to improve weight loss and decrease other anthropometrical indices. The purpose of this study was to assess the effect of a diet high in fiber on body weight, BMI, and waist circumference (WC).Methods: One hundred forty overweight/obese subjects aged from 20-30 years old participated in the study. Body weight (BW), body mass index (BMI) and waist circumference (WC) was measured after one month period in which the subjects consumed diet high in dietary fiber (38 g/d/men, 25 g/d/women). SPSS was used for the analysis of data and statistically significant difference was set at P> 0.05.  Results: BW, BMI and WC were clinically reduced before and after intervention in both males and females. However, these changes were not statistically significant. Percent changes on BW for female and male subjects were 1.45 (95%CI: -12.68, 15.58), P>0.05 and 1.12 (95% CI: -13.58, 15.82), P>0.05, respectively.Conclusion: The high fiber diet did not significantly reduce body weight and WC. Even though there was a small clinically reduction on BW, BMI and WC, however this was not statistically significant. The results, even though were not supportive, they should not discourage people from consuming foods high in fiber, due to other beneficial effects in their health such as decreasing the risk of cancer, lipidemia, type 2 diabetes and metabolic syndrome.

Exercise can reduce androgen and insulin levels in polycystic ovary syndrome (PCOS) patients. Finasteride is also presumed to improve the developing follicle environment. Therefore, the aim of this study was to observe the effects of the combination of exercise and finasteride therapy on hormone levels and ovarian morphology in rats with polycystic ovary syndrome. Forty female rats were randomly divided into five groups (n=8 each group): the PCOS sedentary group (P-Sed), PCOS exercise group (P-Ex), PCOS finasteride and sedentary group (P-FSed), and PCOS finasteride and exercise group (P-FEx), and healthy, age-matched rats were used as controls (CO). The results indicated that the levels of FINS in the P-FEx group were significantly lower than those in the P-Sed and P-FSed groups, while the ratio of fasting blood glucose (FBG)/fasting serum levels of insulin (FINS) in the P-FEx group was significantly higher than that in the P-Sed and P-FSed groups. Compared to the P-FEx group, serum levels of TT (total testosterone) in the P-Sed and P-FSed groups were significantly increased. The thickness of the follicular membrane and the number of atresia follicles in the P-FEx and CO groups were significantly lower than those in the P-Sed group, but there was no significant difference between the P-Ex and P-Sed groups. These results show that the combined usage of exercise and finasteride does not alter the effects of exercise on increasing insulin sensitivity and reducing androgen levels. There is also a synergistic effect of exercise and finasteride on the morphology of the ovary, including a reduced number of atresia follicles and thickness of the follicular membrane.
