The effect of physiological concentrations of caffeine (purified from Persian tea) on adenosine deaminase (ADA) activity at physiological and pathological concentrations of adenosine (as substrate) in 50 mM Tris-HCl buffer (pH 7.3) at 37°C was investigated, using UV-VIS spectroscopy. ADA exhibited a bi-phasic activity behavior and both phases showed positive cooperativities indicating adenosine...

extract   until recent years pharmacological researches focused on pathogeneses and abnormality in organogenesis but now researchers are studying drugs physiological disorders in pregnancy. these studies are specially focused on mothers and fetus, regulatory mechanism of passing drugs through placenta and movement of drug' materials between barriers of milk and blood in the breast. also th...

the effects of prolonged administration of methylthiouracil were studied on several physiological parameters pertinent to the thyroid function in dog. though the individual variations of the measured parameters were not consistent but the statistical differences of diminution of basal metabolism rate, respiration rate and erythrocyte count- were significant brief explanations for the mechanism ...
