To compare the effects of two different regimens of intravenous hydration and oral hydration on the duration of active labor. Two hundred and ninety-three low risk term primigravida in active labor were randomized into three groups. The first group had 99 patients who received oral fluids only, the second group of 98 patients received intravenous Ringer(More)
An enzyme-based drug, L-asparaginase, was produced by Nocardia levis MK-VL_113 isolated from laterite soils of Guntur region. Cultural parameters affecting the production of L-asparaginase by the strain were optimized. Maximal yields of L-asparaginase were recorded from 3-day-old culture grown in modified asparagine-glycerol salts broth with initial pH 7.0(More)
AIMS To isolate and identify the bioactive compounds produced by Nocardia levis MK-VL_113. METHODS AND RESULTS Cultural characteristics of Noc. levis isolated from laterite soils of Guntur region were recorded on International Streptomyces Project media. Morphological studies of the strain through scanning electron microscopy revealed the clear pattern of(More)
Production of chitinase by Streptomyces tendae strain TK-VL_333 isolated from laterite soils of the Guntur region, India, was studied in chitin yeast extract salts (CYS) broth. The effect of cultural and nutritional conditions on chitinase productivity of the strain was recorded. The strain elaborated high yields of chitinase when cultured in 1% w/v(More)
Cultural factors affecting the production of L-asparaginase by Streptomyces tendae isolated from laterite soil samples of Guntur region were investigated on glycerol-asparagine-salts (modified ISP-5) broth. Optimal yields of L-asparaginase were recorded in the culture medium with the initial pH 7.0 incubated at 30 degrees C for 72 h. The strain utilized(More)
An Actinobacterium strain isolated from laterite soils of the Guntur region was identified as Streptomyces sp. TK-VL_333 by 16S rRNA analysis. Cultural, morphological and physiological characteristics of the strain were recorded. The secondary metabolites produced by the strain cultured on galactose-tyrosine broth were extracted and concentrated followed by(More)
An Actinomycete isolate found to be prominent in the laterite soils of Acharya Nagarjuna University (ANU) Campus, Guntur was identified as Nocardia levis MK-VL_113 by 16S rRNA analysis. Cultural, morphological and physiological characteristics of the strain were recorded. Screening of secondary metabolites obtained from 4-day old culture broth of the strain(More)
CONTEXT Critical care units provide a favourable environment for the antimicrobial resistant organisms to disseminate. There is recent increase in number of extended spectrum beta lactamase (ESBL) producers because of the emergence of CTX M Beta lactamases produced by Enterobacteriaceae. They colonize the intestinal flora and spread with greater intensity(More)
Coronary Heart Disease (CHD) is the leading cause of deaths in the developed and developing countries. CHD is always due to atherosclerosis. A number of risk factors have been reported for atherosclerosis. Of these, the major risk factors are high cholesterol level, hypertension, smoking and diabetes mellitus. Fifteen patients with coronary heart disease(More)
