LIBERATION OF CATECHOLAMINES FROM BLOOD PLATELETS

Stability of catecholamines in whole blood, plasma, and platelets.

Checking catecholamine stability in whole blood, plasma, and platelets, we found that specimens stored at room temperature or frozen for periods ranging from 1.5 h to three weeks show no significant difference in measured catecholamine concentration. The implications of these findings are discussed.

Effects of catecholamines on the formation of adenosine 3':5'-cyclic monophosphate in human blood platelets.

The source of HLA molecules on platelets: Does platelets adsorb soluble HLA molecules from their environment?

Background: The origin and function of human leukocyte antigen (HLA) class I molecules on platelets are still highly arguable. Given the differences in the results of the previous studies in this regard, the lack of research in recent years, and the clinical importance of HLA class I molecules, the absorption capacity of platelets for soluble HLA class I molecules was studied in this investigat...

Biochemistry of Blood Platelets

Due to the scope of the discipline, an annual survey of teratology must encompass a broad spectrum of findings from the bio-medical sciences. The first volume in this series does range topically in including reviews on aspects of cytogenetic, pharmacological, radiobiological, and immunological problems. If a field such as teratology is to be reviewed, one cannot expect a high degree of correspo...

To Blood Platelets

I ‘ HAS LONG BEEN KNOWN that blood platelets are isoantigenic.’ Serum isoantibodies reacting with platelets have been repeatedly demonstrated in 1)citieflts ‘ho have received multiple blood transfusions, and in multiparous vomen.’’4 The iiicidence of isoimmunity to blood platelets in niultitransfused iNitients has been studied mainly by the the anti-human globulin consumption,’2 the indirect Co...
