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.

PURPOSE: Self-directed and supervised exercise were compared with usual care in a clinical trial designed to evaluate the effect of structured exercise on physical functioning and other dimensions of health-related quality of life in women with stages I and II breast cancer. PATIENTS AND METHODS: One hundred twenty-three women with stages I and II breast cancer completed baseline evaluations of generic and disease- and site-specific health-related quality of life, aerobic capacity, and body weight. Participants were randomly allocated to one of three intervention groups: usual care (control group), self-directed exercise, or supervised exercise. Quality of life, aerobic capacity, and body weight measures were repeated at 26 weeks. The primary outcome was the change in the Short Form-36 physical functioning scale between baseline and 26 weeks. RESULTS: Physical functioning in the control group decreased by 4.1 points, whereas it increased by 5.7 points and 2.2 points in the self-directed and supervised exercise groups, respectively (P = .04). Post hoc analysis showed a moderately large (and clinically important) difference between the self-directed and control groups (9.8 points; P = .01) and a more modest difference between the supervised and control groups (6.3 points; P = .09). No significant differences between groups were observed for changes in quality of life scores. In a secondary analysis of participants stratified by type of adjuvant therapy, supervised exercise improved aerobic capacity (+3.5 mL/kg/min; P = .01) and reduced body weight (−4.8 kg; P < .05) compared with usual care only in participants not receiving chemotherapy. CONCLUSION: Physical exercise can blunt some of the negative side effects of breast cancer treatment, including reduced physical functioning. Self-directed exercise is an effective way to improve physical functioning compared with usual care. In participants not receiving chemotherapy, supervised exercise may increase aerobic capacity and reduce body weight compared with usual care.

The aim of the present study was to determine the effect of chedu and mattha on growth performance of Murrah buffalo calves. To assess the effect of chedu and mattha on growth rate, 20 growing buffalo calves of around 1 year of age and approximately of same weights were selected and were divided into 4 treatment groups having 5 animals in each group. The animals had access to ad libitum berseem hay as the basal roughage T0 (Control), T1 (Administration of mattha @ 2% of body weight with salt @ 0.5% of mattha), T2 (Application of chedu on their body @ 150 g per animal), T3 (Administration of mattha and application of chedu). Body weight of all buffalo calves was recorded at 15 days interval during the experimental period. From 75th day of experiment, significant effect (P<0.05) was observed in body weight, heart girth and height at withers of treatment groups as compared to control group whereas, body length and paunch girth showed significant effect (P<0.05) on 90th day of experiment. The results further indicated that use of chedu and mattha improved the health status of the calves and helped to attain a comparatively higher body weight and an early puberty. It can be concluded on the basis of findings of present research work that the use of chedu and mattha may be recommended for supplementation of calves’ diet, as it improves the health status of the calves and helps in the attainment of higher body weight and an early onset of puberty in the calves.
