    Notes: Abstract Administration of nifedipine to mice over a period of six months caused a significant (p〈0.05) decrease in neutrophilic functions viz superoxide generation, coupled to NADPH oxidase activity as well as NADPH production by HMP shunt. Properties like chemotaxis and phagocytosis showed a similar decrease. From this study, it is seen that nifedipine causes neutrophil functional abrogation which is therefore an apparent concern for the prolonged usage of the drug. However, relevance of the mouse model to clinical situation needs further investigation.

    Notes: Summary Natural history of myocardial dysfunction due to chronic contractile deficit consists of physiological and pathophysiological adaptations culminating in congestive heart failure. Among the mechanisms considered is the combination of compensatory as well as the harmful overcompensatory role of the adrenergic system during the genesis of a congestive heart failure “spiral” due to the chronic treatment with adriamycin. Refractoriness of this spiral to various inotropic agents may involve reduced sympathetic support of the myocardium, structural loss of contractile elements and abnormalities of the Ca2+ metabolism.
