RESUMO
Extensive research has demonstrated the protective properties of antioxidants, which scavenge reactive oxygen species and their precursors, as well as up-regulate enzymes involved in the repair of cellular damage. Several case-control studies have showed higher blood levels of antioxidants and decreased oxidative stress in younger individuals when compared with older ones. Cell damage caused by free radicals appears to be a major contributor in aging and degenerative diseases of aging such as cancer, cardiovascular disease, cataracts, compromised immune system, rheumatoid arthritis and brain dysfunction. The objective of this study was to determine the variation of Circulating levels of selected antioxidants (enzymic and non enzymic) and oxidative stress marker in younger and older humans. The results showed that a majority of the younger age group participants showed a significant increase in enzymic and nonenzymic antioxidant status and a decrease in oxidative stress when compared with the older age group.
RESUMO
A study was undertaken for evaluating the hypoglycemic and hypolipidemic effects of an ayurvedic medicine "Rajanyamalakadi" containing Curcuma longa, Emblica officinalis and Salacia oblonga in type II diabetic patients over a period of 3 months. Ethical committee consent for the study was given by the Director, Indian Systems of Medicine, Kerala. A total of 43 patients with established diabetes mellitus as adjudged from clinical features and FBS values, appeared for the camp (Age group 35-75 yrs). An informed consent for the study was obtained from each patient. The clinical proforma was given to each patient to collect data such as height, weight, diet pattern, previous history of illness etc. The ongoing antidiabetic medications were stopped under medical supervision and the patients were provided with 'Rajanyamalakadi' tablets (dose 1-2 tablets each weighing 500mg). The dosage of the drug was decided by the supervising medical officer on a case to case basis, taking note of the clinical conditions and responsiveness of the patients. The patients were monitored for three months, who were divided into 6 groups based on their age and again into two groups, 5 & 6, based on their mean FBS values. ie; Normal Persons, Diabetics of age groups 35-45yrs, 46-55yrs, >55yrs and those with FBS < 145.9 mg% and > 145.9 mg%. The Ayurvedic medicine "Rajanyamalakadi" has showed significant antidiabetic, hypolipidemic and antioxidant effects. In addition to that significant ameliorating effects on the elevated serum AST and ALT activities were also demonstrated by the treatment. The nutraceuticals present in the drug like Terpenoids, Polyphenols, Curcumin etc are responsible for the medicinal effects.
