One of the impediments precluding long-term storage of platelets for blood transfusion is that refrigerated platelets are rapidly cleared from the circulation upon transfusion. New evidence suggests that this clearance is mediated in the liver by the Mac-1 integrin on Kupffer cells recognizing clustered GPIb receptor on platelets, leading to platelet phagocytosis.

PROGRESS IN CHEMICAL TOXICOLOGY, Vol. 2 Edited by A. Stolman. (Pp. x + 416. 100s.) New York and London: Academic Press. 1965. This book follows the publication of 'Toxicology, Mechanisms and Analytical Methods', Volumes 1 and 2, in 1960-61, and Volume I of 'Progress in Chemical Toxicology' in 1963. It consists of six main chapters by seven American and two British authors. Very nearly half the ...

fluctuations in salinity impose stress on the physiology of the exposed fish population and can modify their structure. it has been noted that changes in blood characteristics and plasma levels serve as the primary link between environmental change and physiological response (mccormick, 2001). ninety healthy adult cyprinuscarpio (c. carpio) were randomly divided into five groups and kept in sal...

abo blood type antigens are polymorphic, inherited structures presented on the surface of red blood cells. although abo blood group antigens is the most important antigens in transfusion medicine, its main role is not clearly clarified. correlation between abo blood group and susceptibility to certain infectious and non-infectious diseases is a controversial issue. since, lack of blood type ant...
