The H4IIE cell bioassay has proven utility as a screening tool for planar halogenated hydrocarbons (PHHs) and structurally similar chemicals accumulated in organisms from the wild. This bioassay has additional applications in hazard assessment of PHH exposed populations. In this review, the toxicological principles, current protocols, performance criteria, and field applications for the assay a...
We describe here a simple, fast, and reliable bioassay method for therapeutic drug monitoring of voriconazole. Fifty-eight clinical and external quality control samples were evaluated with this microbiological assay, and results were compared with those obtained with a previously validated chromatographic method. A good correlation between both assays was observed. This particular microbiologic...
is an important human fungal pathogen, in terms of both its Candida albicans clinical significance and its use as an experimental model for scientific investigation. Although this opportunistic pathogen is a natural component of the human flora, it can cause life-threatening infections in immunosuppressed patients. There are currently a limited number of antifungal molecules and drug targets, a...
in the present work, the bioassay screening of the essential oil and various extracts of two plants including fruits of heracleum persicum desf. and rhizomes of zingiber officinale rosc. have been studied with brine shrimp test. there is only one report about cytotoxicity of h. sphondylium in literature and so h. persicum has been used as second selection. at first essentials oil and various ex...
spirulina platensis, a cyanobacterium of economic important was studied for the tolerance to cadmium. the bioassay studies showed the ec50 value to be 1.53 mg/g. the cyanobacterium was very sensitive to low metal concentration and the productivity was also reduced. the chlorophyll pigments reduced with decreasing the algal biomass. the algal survival rate showed a marked reduction in their surv...
plasma renin activities (PPA) were measured before treatment and 5 weeks and 10 weeks after the beginning of the administration of the above-mentioned diet. The data were compared with those of non-treated age-matched SHR controls. Each group consisted of more than 8 SHRs and blood samples were taken immediately after decapitation. PCA was measured by double isotope derivative method and PRA by...
An improved bioassay for fluconazole was developed. This assay is sensitive in the clinically relevant range (2 to 40 micrograms/ml) and analyzes plasma, serum, and cerebrospinal fluid specimens; bioassay results correlate with results obtained by high-pressure liquid chromatography (HPLC). Bioassay and HPLC analyses of spiked plasma, serum, and cerebrospinal fluid samples (run as unknowns) gav...
Objectives: Grewia paniculata (Family: Malvaceae) has been used to treat inflammation, respiratory disorders and fever. It is additionally employed for other health conditions including colds, diarrhea and as an insecticide in Bangladesh. The aim of the present study was to investigate the antibacterial and cytotoxic activities of different extracts of Grewia paniculata. Materials and Methods: ...
