ABSTRACT
Shilajit is a mineral-rich complex organic compound used in the traditional system of Ayurvedic medicine for treating hypertension and improving the cardiac function with many herbomineral preparations. However, very little experimental evidence is available about its effect on the cardiac function. We used Daphnia as a model organism for observing the effect of shilajit on its heart due to its myogenic properties and its response to number of cardioactive drugs that are known to affect human heart function. Genome of Daphnia shows the strongest homology with the human genome. These characteristics of Daphnia make it an ideal organism for biomedical research. Our results suggest that this complex organic compound lowers the heart beats as its concentration increases from 1.0 to 100 ppm. The beats come to near normal condition at 1000 ppm. Above 1000 ppm, the beats are very fast and impossible to count. These results indicate a negative chronotropic effect on the Daphnia heart at low concentrations and a positive chronotropic effect to arrhythmia and fi nally failure at increasing higher concentrations of shilajit.
ABSTRACT
OBJECTIVE: To assess their reproductive health problems and help seeking behaviour among urban school going adolescents. METHOD: A sample of 300 urban school going adolescents between 11-14 years were chosen at random and assessed using four tools namely, self administered questionnaire : provision of adolescent friendly services; medical screening and focus group discussions. RESULTS: Seventy two percent girls and 56% boys reported health problems during survey with an average of 1.93 complaints per girl and 0.5 complaints per boy. However, only 43% girls and 35% boys reported to the clinic voluntarily to seek help and only one fifth the amount of problems were reported at the clinic in comparison to the quantum of problems reported in survey, which probably reflects a poor health seeking behaviour. A medical checkup with emphasis on assessment of reproductive health and nutritional status helped in detecting almost the same number of reproductive health problems as reported by them in survey. This intervention helped to increase the client attendance in subsequent period of next one year from 43% to 60% among girls and from 35% to 42% among boys. CONCLUSION: Our study shows that to increase help seeking behaviour of adolescents, apart from health and life skill education, their medical screening with a focus on reproductive health by trained physicians, parental involvement, supported by adolescent friendly centers (AFC) for counseling, referral and follow up are essential.
