diuretics are the agents which cause increase in excretion of urine. diabetes mellitus (dm) is a multi-factorial disorder characterized by hyperglycemia resulting from an increased hepatic glucose production and diminished insulin secretion. the present study was undertaken to study the diuretic and anti-diabetic activity of esculin. esculin was found to have potent diuretic activity in normal ...

A total of 232 isolates of Enterobacteriaceae and 19 Pseudomonas species were tested on bile-esculin-agar. Only the Klebsiella-Enterobacter-Serratia group produced blackening of the medium.

The ability of enterococci to cause severe disease in humans and their relative resistance to chemotherapeutic agents make it desirable to rapidly differentiate these organisms from other streptococci. We developed and evaluated a test that within 2 h distinguishes enterococci from other alpha-, beta-, or nonhemolytic streptococci in a buffered solution containing 0.2% esculin and 5% sodium chl...

The predominant dental plaque flora was compared between two grouf)s of adult beagle dogs. (1> ten with gingivitis and (2) ten with advanced periodontitis. Plaque from a maxillary third premolar was cultured under strict anaerobic conditions. Specimens comprising the marginal periodontal tissues were taken at the plaque sampling site and analyzed for some histological parameters of periodontal ...

BACKGROUND Hymenodictyon excelsum is a medicinal plant traditionally used for tumor treatment as it contains phytochemicals of anthraquinone and coumarin class. OBJECTIVES The aim of the present study was to unfold the therapeutic value of selected phytocompounds of Hymenodictyon excelsum in prostate cancer. MATERIALS AND METHODS Eight phytochemicals were selected based on the literature se...

Pfizer selective enterococcus (PSE) and KF agars were compared for their recovery of fecal streptococci from sewage effluent on membrane filters. The results showed that PSE agar is highly selective for the enterococci. The tan color resulting from esculin hydrolysis, which was not always visible on the surfaces of the colonies, is not considered a necessary differential characteristic on PSE a...

Strains (105) of Yersinia pseudotuberculosis isolated in Brazil between 1982 and 1990 were bio-serotyped. They were also studied for plasmid profile, autoagglutination and calcium dependence at 37 degrees C, Congo red uptake, pyrazinamidase activity, esculin hydrolysis, salicin fermentation and drug sensitivity: 95.24% were biotype 2, serogroup O:3; 2.86% were biotype 1, serogroup O:1; and 1.90...

The present study illustrates the optimization and characterization of β-glucosidase from a bacterial isolate, strain SG9. Sixty-eight different variables were first screened by one factor at a time method. The screened variable optimization was then performed by Plackett-Burman design followed by Box-Behnken response surface methodology. Thirty-one variables were screened, of which five variab...
