Plasma concentration of adrenocorticotropic hormone in traffic policemen.
The aim of this study is to evaluate whether traffic policemen exposed to urban pollutants and possible psycho-social stressors could be at risk of changes on plasma adrenocorticotropic hormone [ACTH(P)] levels compared to a control group. Traffic policemen were matched by sex, age, length of service and drinking habit (<50 g of wine or beer per day) with a control group after excluding princip...
متن کاملInfluence of centrifugation temperature on the plasma total homocysteine concentration.
creased clearance of the sialic aciddeficient transferrin isoforms (CDT) via the asialoglycoprotein receptor. The underlying mechanism for the increased CDT in our patient might be different from that in viral liver cirrhosis. To explore the etiology of this finding, measurements of neuraminidase and sialyltransferase activity (9 ) and of the sialyltransferase mRNA concentration (10 ) may be us...
متن کاملPreanalytical stability of adrenocorticotropic hormone depends on time to centrifugation rather than temperature.
To the Editor: Preanalytical factors can affect reliability of hormone assay results. Adrenocorticotropic hormone (ACTH) in blood is considered highly unstable because of proteolytic degradation (1–4), so storage of blood samples on ice until analysis is recommended. In clinical practice, however, this procedure may present logistical problems because most samples for ACTH measurement must be s...
متن کاملThe effect of cortisone and adrenocorticotropic hormone on the dehydroascorbic acid of human plasma.
It is well known that ascorbic acid in aqueous solution is easily and reversibly oxidized to dehydroascorbic acid, and it is believed that above pH 4 the latter can undergo irreversible change, possibly to diketogulonic acid, as a preliminary to further oxidation. The possibility of the existence of dehydroascorbic acid or diketogulonic acid in blood plasma, however, has been generally ignored ...
متن کاملThe effect of hypophysectomy and adrenocorticotropic hormone on the alkaline phosphatase of rat plasma.
It is well known that the phosphatase content of bone, kidney, liver, and blood may change under varying conditions of growth, diet, and disease (1). Among these tissues, blood perhaps furnishes the over-all changes of this enzyme activity. Weil (2) found a rise in plasma phosphatase activity from birth to maturity during the growth of normal rats. Kinard and Chanutin (3) have reported that the...
