The authors studied the factors affecting drug use pattern, cost of therapy, and the association between the pattern of drug use and survival as well as the duration of stay in a prospective, observational study in an intensive care unit between February and May 2005. Data were collected regarding drugs used, severity of the disease, and their outcome. The mean +/- SD of the Acute Physiology and Chronic Health Evaluation (APACHE III) and Glasgow Coma Scale (GCS) scores of 84 patients were 52.2 +/- 19.4 and 7.5 +/- 2.4, respectively. Although the mean number of drugs at the time of admission to the intensive care unit was 5.3, it increased to 12.9 on the first day and 22.2 during the entire stay. More than 50% of the average expenditure on drugs and nutrition was accounted by antibiotics. Requirement of insulin or inotropes signified an adverse outcome on mortality (odds ratios of 3.43 and 8.44, respectively). In conclusion, there is a tremendous impact of antibiotic use on the cost of therapy in the intensive care unit. The requirement of certain drugs such as insulin and inotropes is of prognostic significance.

Endophytes are a potent source of bioactive compounds that mimic plant-based metabolites. The relationship of host plant and endophyte is significantly associated with alteration in fungal colonisation and the extraction of endophyte-derived bioactive compounds. Screening of fungal endophytes and their relationship with host plants is essential for the isolation of bioactive compounds. Numerous bioactive compounds with antioxidant, antimicrobial, anticancer, and immunomodulatory properties are known to be derived from fungal endophytes. Bioinformatics tools along with the latest techniques such as metabolomics, next-generation sequencing, and metagenomics multilocus sequence typing can potentially fill the gaps in fungal endophyte research. The current review article focuses on bioactive compounds derived from plantassociated fungal endophytes and their pharmacological importance. We conclude with the challenges and opportunities in the research area of fungal endophytes.

A new, simple and sensitive spectrophotometric method in ultraviolet region has been developed for the determination of rosuvastatin calcium in bulk and in pharmaceutical formulations. Rosuvastatin exhibits absorption maxima at 244 nm with apparent molar absorptivity of 7.2345 ×104L/mol.cm in methanol. Beer’s law was found to be obeyed in the concentration range of 2-18 µg/mL. The method is accurate, precise and economical. This method is extended to pharmaceutical preparations. In this method, there is no interference from any common pharmaceutical additives and diluents. Results of the analysis were validated statistically and by recovery studies
