Twenty four Wistar strain albino rats were used for the investigations. Lecithin 50 and 100 mg/kg b wt was administered for
1 week by oral route. Liver damage was induced by intra peritoneal administration of 400 mg/kg b wt d-galactosamine on the last day. At the end of the study animals were sacrificed and liver enzyme levels, histopathology, mitochondrial
integrity, expression of p53, Bax and Bcl-2 mRNA levels were studied. Increases in the liver enzyme levels by d-GalN were significantly inhibited by pretreatment with lecithin. Histopathological observation further confirmed the hepatoprotective
effect of lecithin. In addition, the disruption of mitochondrial membrane, up regulation of Bax and down regulation of Bcl-2
mRNA levels in the liver of d-GalN intoxicated rats were effectively prevented by pretreatment with lecithin. The results of the present study validate
our conviction that d-GalN causes hepatic damage via mitochondrial pathway involving Bax and Bcl-2. 相似文献

Zinc (Zn), copper (Cu), magnesium (Mg) and retinol levels were studied in serum and tissue of the patients with prostatic carcinoma (Ca), benign hyperplasia (BHP) and control subjects. Zinc and retinol levels were low in both serum and tissues of patients with carcinoma, while in BHP, both zinc and retinol level were decreased. Copper levels were high in serum and tissues of both BHP as well as carcinoma patients. Magnesium levels were elevated in both serum and tissues of cancerous patients. The results indicate that Zn, Cu, and Mg metabolism is disturbed in malignancy. 相似文献

We conducted a controlled study on effect of selected yoga practive in the control and management of 50 cases of essential hypertension and equal number of healthy (nonhypertensive) controls. Free radical cellular damage is considered to be the underlying common biological factor in essential hypertension. We, therefore, investigated lipid profile lipid peroxidation and Na+K+ ATPase activities of plasma membrane of subjects with essential hypertension. It was found that hypertensive subjects had an elevated lipid peroxidation and decreased Na+K+ ATPase activity in plasma membrane as compared to normotensive healthy controls, the specific yoga training protocol which was administered not only helped to decrease blood pressure but also retard the progression of ceellular damage due to free radicals. 相似文献

The idea of adiabatic invariance is presented in the context of simple classical mechanical models. The adiabatic invariant jumps across the separatrix — an attempt has been made to bring out the basic ideas underlying the Melnikov-Arnold integral. This becomes important as soon as a perturbation to a regular, stable system makes it dynamically unstable. 相似文献

The study of the basis of mental phenomena or the mind has always intrigued humans. Our current understanding of the functioning of the brain is the result of insightful research by many scientists, which has led to a detailed knowledge of brain structure and how this structure makes it possible for the mind to emerge from it. 相似文献

Outpatient counseling is a relatively new concept and form of clinical practice in India. This article provides an overview
of the need for and current status of counseling and family therapy in India. Examples of training programs are presented,
and future prospects for the counseling and family therapy professions are highlighted. The authors discuss therapeutic issues
that clinicians may need to consider when working with Indian clients, as well as some of the potential barriers to counseling
individuals, couples, and families in or from the Indian subcontinent. The future of these professions looks bright and parallels
India’s rapid development as a nation. 相似文献

This paper studies collective formations of multi-agent systems, modeled with unicycle dynamics, while admitting heterogeneity in both controller gains and speeds of the agents along with saturation on the controller outputs. This addresses a practical scenario where the speeds are usually nonidentical and the controller gains may vary due to imperfect implementation. The paper analyzes the effect of both heterogeneous controller gains and speeds simultaneously on the collective formations obtained by optimizing the average linear momentum of the group of agents. A detailed analysis of the two-agent system is given in the paper and some results on the locus of the collective centroid with varying controller gains are obtained. Effect of saturation is also studied for two cases when the controller gains are bounded and when the control efforts are bounded. Simulation examples are given to illustrate the theoretical findings. 相似文献

In view of sufficient body of evidence to substantiate the role of free radical mediated oxidative injury in myocardial infarction
(M.I.), the utility of exogenous supplementation with antioxidant substance, vitamin E was studied. Forty patients of acute
myocardial infarction were divided into two equal groups, one who received vitamin E and the other who did not. Plasma MDA
levels showed a reduction in patients of M.I. who received vitamin E as well as in those who did not, however, the decrease
was significantly more in the vitamin E treated subgroup. 相似文献
