Abstract

A medicinal herb can be viewed as a synthetic laboratory as it produces and contains a number of chemical compounds. Gas chromatography (GC) and mass spectroscopy (MS) can be used to study traditional medicines and characterize the compound of interest. Indigofera viscosa Lam. is herb distributed in hill slopes of southern peninsular India. The macerate of the crushed whole plant is used as rectal application, twice a week for one week, to stop diarrhea. Sterols, triterpenes, polar and other constituents in whole plant of Indigofera viscosa Lam. were analyzed by gas chromatography-mass spectrometry. Over 23 compounds were identified. Sitosterol and stigmasterol were the most abundant of sterols identified in the sterol fraction.

Abstract

Nature has created plants in the world for every ailment and there is a cure for every diseases and man has to find it. The plant Tephrosia villosa (L.) Pers. is a medicinally important and the fruits are edible. Systematic and detailed Pharmacognostical studies were performed on Tephrosia villosa (L.) Pers.. The studies include anatomical characters of leaf, stem and ischolar_mains, fluorescence analysis of the leaf, stem and ischolar_main powders and their extracts in petroleum ether (40-60^o), benzene, chloroform and methanol in the selected species. Quantitative determination such as moisture content, total ash, water-soluble ash, acid insoluble ash, water extractive values and sulphated ash have also been made. Preliminary phytochemical analysis of the extracts was done and the results showed that tannins, protein and steroid were predominantly present in all the form extracts of leaf, stem and ischolar_main.

Abstract

Automobiles are 'necessary evils'. On one hand they have made living easy and convenient, but on the other hand they have also made human life more complicated and vulnerable to both toxic emissions and increased risk of accidents. Urban people are the most affected, and among the worst sufferers are traffic policemen who are particularly close to the automobile exhaust. Work pressure and high level of pollution are taking their toll on traffic policemen. To assess the knowledge, attitude and practices of traffic policemen towards the health effects caused by vehicular pollution, the present study has been carried out on 52 randomly selected traffic policemen in Tirunelveli Corporation area. The questionnaire included questions regarding the self-assessment of the policemen about their respiratory symptoms, hearing ability, past and present exposure to loud sound and the use of personal protective devices such as earplugs and earmuffs. The questionnaire was filled up by the subjects. The mean age of policemen was 39.2 ± 7.8 years, and the mean years of exposure was 3.4 ± 1.1 years. The self-assessment of hearing by traffic policemen suggests that most of the traffic policemen have normal hearing. However, a systematic study with audiometry of these subjects is recommended. Respiratory symptoms, including cough and related health problems, were observed in 30 policemen. The results show a major prevalence of respiratory symptoms and allergic sensitization in exposed traffic police.
