Background
Heavy metals are natural components of the earth’s crust and are considered as constant environmental pollutants since they cannot be degraded or destroyed easily. Cadmium (Cd) is present primarily in the ores of zinc, copper, or lead; the extraction and processing of which releases large quantities of cadmium into the atmosphere, hydrosphere, and soil thereby contaminating the human environment. The present study aimed to investigate the possible protective and therapeutic effects of garlic and tomato extract on cadmium-induced AChE activity, biochemical parameters along with the pathological changes in the brain tissue of mice.
Methods
Male Swiss albino mice (n = 40) were divided into several experimental (protective and therapeutic) groups and were given single dose of cadmium (6 mg/kg bw) with supplementation of garlic (100 mg/kg bw) and tomato (50 mg/kg bw) extract for 15 and 30 days under protective and therapeutic study.
Results
Cadmium-treated mice showed a significant decline in AChE (p < 0.01) level and total proteins (p < 0.0001) but a nonsignificant decrease in glycogen, cholesterol in the brain tissue activity as compared to control group. The histological study also showed degeneration in the form of vacuolation, congestion, hyperemia, lymphocytic infiltration, and edema in the brain (cortex and hippocampus) of Cd-treated mice. But the antioxidant-treated groups showed significant increment in AChE level and other biochemical parameters in the protective study. But there were significant variations in the therapeutic study, and this was also confirmed by the histological analysis of the brain. Both tomato and garlic administration showed more attenuation in the brain AChE activity, and it may be due to the strong antioxidant potential of their constituents.
Conclusion
We can conclude that cadmium exposure should be avoided as it causes neuropathological effects. But in daily life, it may not be possible, so we should regularly intake natural antioxidants which may neutralize the effects of heavy metals to some extent.
Blood clotting response (BCR) test is a faster method with fewer ethical constraints than feed-testing and is widely used to monitor resistance. The second-generation anticoagulant, bromadiolone is being used to control rodents all over India for the last several years. To investigate whether its use has resulted in development of resistance in house rat, Rattus rattus, BCR test was standardized. Plasma samples of 15 rats of both the sexes were pooled separately and diluted with phosphatebuffered saline (pH 7.4). Ten different dilutions of plasma i.e. 4, 5, 6, 8, 10, 20, 40, 60, 80, 100% were tested for Prothrombin Time (PT) and International Normalized Ratio (INR) using rabbit brain thromboplastin reagent in coagulation analyzer. Time to clotting was converted into percent clotting activity (PCA) relative to plasma dilutions, to plot a standard curve. The PT of 15.7 and 17.6 sec for 100% plasma corresponded to INR of 0.8 and 0.9 in male and female rats, respectively. PCA of 22.3% corresponded with PT and INR of 70.3 sec and 3.8, respectively in male rats and PCA of 27.6% corresponded with PT and INR of 63.6 sec and 3.5, respectively in female rats. Data for PT and INR and standard curve for PCA vs PT prepared during present study can be further used to determine current status of bromadiolone resistance in R. rattus populations based on discriminating dose of bromadiolone.
Background: Development of peak bone mass and premenopausal bone loss is determined by the menstrual status of women. Decline in bone mass with age becomes accelerated during menopause. Menopausal bone loss refers to the accelerated bone loss that occurs during the BM) of premenopausal and post-menopausal women, to identify the contributing factors associated with BMD among pre and post-menopausal women, to compare the level of BMD and the contributing factors of pre-menopausal women with post-menopausal women.Methods: It was quantative research approach and epidemiological analytic research design was used. Total enumeration technique was adopted in this study.Results: Analysis of data was done in accordance with the objectives of the study. Findings show that among premenopausal women 45.10% of the women had osteopenia and 8.20% of the women had osteoporosis, among postmenopausal women 50.00% of the women had oestriopenic and 41.2% of the women had osteoporosis. The analysis shows that factors such as BMI, Health status, life style, age, economic status and dietary patter plays important role to accelerate the level of T-score more than -1 in both group either premenopausal women or post-menopausal women. It shows the significance at the level of p<0.001.Conclusions: The study was completed in July 2016, concludes that there are many factors that can lead to have risk of osteoporosis related fracture. As age is increased the risk is also increased to get the fracture. Every woman can go for screening of BMD test to control the risk of fracture.
