    Notes: Summary The content of arginine vasopressin in the brain stem and neurohypophysis of adult spontaneously hypertensive rats was measured by radioimmunoassay and the values were compared to those measured in normotensive Wistar-Kyoto rats. In the brain stem of hypertensive rats, AVP content was decreased by 77% while neurohypophyseal AVP content was increased by 26%. The results demonstrate that brain stem AVP levels and neurohypophyseal AVP levels may change differentially and they are consistent with the possibility that brain stem AVP may be involved in altering cardiovascular reflex activity.

    Notes: Summary Neural tube defects in infants of diabetic mothers constitute an important and frequent cause of neonatal mortality/morbidity and long-term chronic handicaps. The mechanism by which normal neural tube fusion occurs is not known. The failure of rostral neural tube fusion seen in mouse embryos incubated in the presence of excess-D-glucose can be significantly prevented by the supplementation of myo-inositol to the culture medium. This protective effect of myo-inositol is reversed by indomethacin, an inhibitor of arachidonic acid metabolism leading to prostaglandin synthesis. Prostaglandin E2 added to the culture medium completely protects against the glucose-induced neural tube defect. These data suggest that the failure of neural tube fusion seen in diabetic embryopathy is mediated through a mechanism involving abnormalities in both the myo-inositol and arachidonic acid pathways, resulting in a functional deficiency of prostaglandins at a critical time of neural tube fusion.

    Description / Table of Contents: Zusammenfassung Im menschlichen Blutplasma wurde vermittels äquilibriumDialyse die Eiwei\bindung für Tetrahydroaldosteronglucuronid mit 35–39% und diejenige für 18-Aldosteronglucuronid mit 54–57% bestimmt. Auf Grund dieser Werte und der früher mitgeteilten renalen Clearance dieser beiden Aldosteronmetaboliten, welche die Eiwei\bindung nicht berücksichtigte [13], ergibt sich für das Tetrahydroaldosteronglucuronid eine renale Clearance im Bereich derjenigen des Inulins und für das 18-Aldosteronglucuronid eine solche im Bereich der PAHClearance.
    Notes: Summary In equilibrium dialysis with human blood plasma and human albumin the protein binding of tetrahydroaldosterone glucuronide was 35 to 39% and the protein binding of 18-aldosterone glucuronide was 54 to 57%. The “uncorrected” renal clearance values of these two aldosterone metabolites, as published bySiegenthaler et al. [13], were “corrected” for protein binding. So the renal clearance of tetrahydroaldosterone glucuronide is similar to the renal clearance of inulin, whereas the renal clearance of 18-aldosterone glucuronide lies in the range of the PAH clearance.
