Background: The unprecedented outbreak of a contagious respiratory disease caused by a novel coronavirus has led to a pandemic since December 2019, claiming millions of lives. Aims and Objectives: The present study was undertaken to estimate the various risk factors associated with COVID, to study the common presenting symptoms and prognosis, and to estimate the degree of association between computed tomography (CT) value in reverse transcription polymerase chain reaction (RT-PCR) with mode of disease transmission in north coastal districts of Andhra Pradesh. Materials and Methods: This was a cross-sectional study comprising of 1462 COVID-positive individuals. It is based on structured questionnaire on demographic, socioeconomic and symptoms, and correlation of clinical pattern with CT value in RT-PCR and further prognosis. Results: Diabetes (6.7%), hypertension (7.5%), and bronchial asthma (8.6%) are the main comorbid conditions. Middle (44.6%) and low socioeconomic status (47.3%) are more susceptible. Male gender (63.5%) is more affected, especially 16–30 years age group (32.4%). Vaccination offers considerable protection from infection. Contact (59.4%) with known case and travel (31%) are main factors that determine disease transmission. Blood group may not play a role in COVID susceptibility. Health careworkers (22.9%) and students (16.2%) are mostly affected. Conclusion: Bronchial asthma, hypertension, and diabetes mellitus are the predominant risk factors associated with COVID. Transmission of the disease is more by virtue of contact with the infected person than by travel.
BACKGROUND:Skeletal muscle relaxants are drugs that are used to relax and diminish tightness in muscles. Many medicinal plants have known to have skeletal muscle relaxant activity. In past studies some Polyherbal formulation containing Ashwagandha as one of the ingredients and its fat extract have shown to have skeletal muscle relaxant activity in experimental animal models. This study is intended to evaluate the skeletal muscle relaxant activity of alcoholic extracts of Withania Somnifera (Ashwagandha) roots in albino mice, as the literature regarding this extract is scarce. METHODOLOGY: Standard drug (diazepam), different doses of Alcohol extract of ashwagandha (50,100, 150 mg/kg) were given orally to mice and muscle relaxant activity was assessed by Rota-rod apparatus. The fall off time from the rotating rod was noted for each group after 1 hour of drug administration. The difference in fall off time among the standard drug and treated mice was taken as an index of muscle relaxation. RESULTS:The test extract at its different doses showed highly signicant reduction in the time spent by the animals on revolving rod in rotarod test when compared to baseline (p < 0.0001) which is highly signicant. On comparison with diazepam, different doses of Alcohol extract showed weak relaxant activity. CONCLUSIONS : The three different doses of Alcoholic extract showed a dose dependent rise in muscle relaxant action. The results are promising for further investigation of efcient skeletal muscle relaxant activity.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
