    Of the two variants of adipose tissue, white fat is traditionally known as a lipid rich tissue which undergoes pathological expansion in obese conditions. To counter the excess accumulation of white fat in states of energy imbalance, the second and unique type of brown fat plays a key role by burning extra energy into heat through a special metabolic pathway. In addition brown fat also plays a vital role in thermoregulation in animals and newborn humans and infants. Recent progress in research areas of these two types of fat tissue has provided compelling evidence to show that they secrete a large number of chemicals that play an important role in body weight control that involves several mechanisms. Brown fat was considered absent in the adult humans until recently. But new techniques have provided ample support for its active existence. Based on the very recent data it has been suggested that brown fat can be a target organ in the treatment of obesity which can lead to exciting and informative outcomes in the future.

    Alcohol addiction is a social problem faced by every country worldwide. Young people are more at risk of this menace. In spite of a clear knowledge and message about the effects of alcohol on individual health and social fabric, it is hard to curb the overuse of this beverage. In the present study, we compared the outcome of a survey using Comprehensive effects of Alcohol (CEOA) in two private Medical institutions in two Asian countries, viz. KMC, Mangalore, India (n=180) and AIMST, Kedah, Malaysia (n=170). The study included both males and female students. The result suggested that the negative reinforcement responses were rated higher in both the study groups. But those who have tasted alcohol before had a higher rating that alcohol may cause positive reinforcement. Both groups of respondents showed similar trend suggesting that the alcohol expectancies are similar in Indian students and Malaysian students. From the results we could conclude that the responses of the two sample groups were comparable to each other. While the male respondents were inclined show higher affinity towards acceptance of alcohol females are very much less so. However, the respondents of both groups appeared to be well aware of the negative aspects of alcohol. Importantly previous exposure to alcohol intake dramatically changed the perception and showed increased inclination towards alcoholism. This study thus provides an important clue to the clinician, counselors and parents regarding the importance of guiding the young people about the alcoholism.

    Ethanol is a testicular toxin and it causes fertility abnormalities with low sperm count and impaired sperm motility in men. The present study was designed to investigate plasma testosterone level and hypothalamic pituitary gonadal (HPG) axis function in alcoholic men and also effect of ethanol on systemic oxidative stress. Forty six male alcohol abusers in the age group 20-40 years were selected. Fifty five, males in the same age group served as control. Alcohol abusers had significantly low plasma testosterone with low luteinizing hormone and follicle stimulating hormone. In addition they had significantly high thiobarbituric acid reactive substances (TBARS), superoxide dismutase and glutathione S-transferase, and low glutathione, ascorbic acid, catalase, glutathione reductase and glutathione peroxidase. Moreover, serum testosterone level in alcoholics negatively correlated with duration of alcohol abuse, and TBARS. Duration dependent decreased serum testosterone level in alcohol abusers might be due to 1) increased oxidative stress which can damage Leydig and supporting Sertoli cells and 2) impaired HPG axis.

    The present study was performed to evaluate the wound healing and antioxidant effect of aqueous extract of Ocimum sanctum Linn. (O. sanctum) in rats. Albino rats of either sex were divided into 2 groups. Group I: Wounded control rats; Group II: Wounded rats administered O. sanctum aqueous extract. Wound breaking strength in incision wound model, epithelization period and percent wound contraction in excision wound model were studied. Using dead space wound model, granulation tissue breaking strength, granulation tissue dry weight, hydoxyproline level in dry granulation tissue, superoxide dismutase (SOD) and catalase levels in wet granulation tissue were estimated in both the groups. Increased wound breaking strength, decreased epithelization period, increased percent wound contraction, increased granulation tissue weight and hydroxyproline concentrations were observed. The increased activity of antioxidant enzymes such as SOD, catalase level in extract treated group compared to controls. Granulation tissue was subjected to histopathological examination to determine the pattern of lay-down for collagen using Haematoxylin and Eosin stains which confirm the results. Owing to wound healing and antioxidant activities, O. sanctum may be useful in the management of abnormal healing such as keloids and hypertrophic scars.
