A total of 9 experiments were carried out at different doses (100, 200 and 400 mg/kg, p.o.) of Dhatri Lauha(DTR)which was studied in different animal model to find out the various degrees of significant action of the drug on mice (Swiss-Webster strain, 20-40 gm body weight). Highly significant (p=0.009) increase in ambulation behavior was observed in Hole board test and highly significant (p=0.005) increase in motor activity was observed in Hole cross test. Open field test showed significant (p=0.036) increase in Standing up behavior. Climbing out test produced a significant (p=0.039)...

The work describes the chemical and biological investigations of Ravenia spectabilis of the family Rutaceae. Some works had been reported previously on this species, but the species grown in Bangladesh have not been studied extensively. Stem bark of the plant was extracted and the extract was fractionated by using standard chromatographic techniques. A total of four compounds were isolated. Isolated pure compounds were identified by their spectral data (1D and 2D NMR). Stem bark of Ravenia spectabilis yielded one alkaloid. The alkaloid has been characterized as arborinine [RS-1]. The other...

Out of 1500 nasopharyngeal swab samples collected from patients who were admitted to different maternity clinics in Dhaka city, 111 optochin resistant strains were isolated. As a confirmatory test of Streptococcus pneumoniae, i.e., Bile solubility was checked. A total of 37 optochin resistant bile soluble isolates were obtained, designated as optochin resistant bile soluble S. pneumoniae as other - hemolytic streptococci are not bile soluble. For further identification, bile soluble isolates were subjected to PCR of the lytA gene specific for S. pneumonia an 32 (87%) isolates were...
