STUDY ON DETECTION METHODS FOR NOREPINEPHRINE IN BIOLOGICAL SAMPLES
Norepinephrine (NE) is an important catecholamine neurotransmitter that acts as a biochemical messenger in central nervous systems and neuronal cells of mammals, which is secreted and released by the adrenal medulla and the noradrenergic neurons during the synaptic transmission. It is often used for treating bronchial asthma, myocardial infarction hypertension and organic heart disease. Abnormal r...

STUDY OF STORAGE PERIODS OF CULTURE SUSPENSION OF STAPHYLOCOCCUS AUREUS
Staphylococcus aureus ATCC 6538 is an important strain of pharmaceutical and biotechnological industries. We studied the viability of culture suspension of Staphylococcus aureus strain ATCC 6538 at 2 to 8°C up to 360 days in 0.9% w/v NaCl. The culture suspension containing 10000 cfu/ml used in the study was stored at 2 to 8°C for 360 days in 0.9% w/v NaCl. Using 10 µl of above culture suspensio...

PROTECTIVE EFFECT OF NYCTHANTHES ARBOR-TRISTIS ON SCOPOLAMINE INDUCED AMNESIA IN RATS “A BEHAVIOURAL AND BIOCHEMICAL APPROACH”
The hydroalcoholic extract of Nyctanthes arbor-tristis (HeNAT) leaf was prepared using Soxhlet apparatus. Memory impairment (amnesia) in male albino rats induced by scopolamine hydrochloride was recorded as transfer latency time (TLT) in EPM model; escape latency time (ELT) and time spent in Q4 target quadrant (TSTQ) in MWM model. Scopolamine markedly decreased the TLT over 2 min, ELT, TSTQ over 9...

COMPARISON OF DIFFERENT SUPERDISINTEGRANTS IN DESIGNING OF FAST DISSOLVING TABLETS OF METOPROLOL TARTRATE
Metoprolol tartrate which is used in the present study is widely used as antianginal properties. Oral bioavailability of metoprolol tartrate is around 40%. In the present work fast dissolving tablets of metoprolol tartrate have been prepared by direct compression method. Formulations were evaluated for precompressional parameters such as angle of repose, % compressibility and Hausner’s ratio. Th...
