[Immune status of pregnant patients especially in possible premature labor].

In this study it could be shown that pregnant women having a normal course of pregnancy had significantly higher levels of T-lymphocytes and T-helper cells compared with non-pregnant women. Also other parameters belonging to cellular immune defence showed a similar--in the sense of an improved immune function--trend (even though this was not statistically significant). In pregnant women with symptoms of threatened prematurity significantly lower levels for lymphocytes.

[Aggregation inhibiting and anticoagulant effects of oligoamines. 13. Improvement in the storage of whole blood and erythrocyte suspensions with oligoamines].

The impairment of the functions of red blood cells or their destruction during storage can be delayed or even inhibited by oligoamines especially RE 1492 (N,N',N''-Tris-(4-phenylbutyl)benzene-1,3,5-trimethanamine). When citrated whole blood (WB) is stored at 4 degrees C for 7 d half of the red blood cells (RBC) have lost their ability to form rouleaux. Addition of 100 mumols/L RE 1492 maintains 50% reaggregability up to day 28th of storage.

Beta-receptor blockade, physical activity, and metabolism.

The adaptation processes under physical activity are regulated through an increase in the sympathetic impulse, whereby the circulation adaptation is mediated specifically by way of beta1-receptors and the energy supply predominantly by way of beta2-receptors. The maximum performance capacity, therefore, is restricted through every form of beta-blockade. However, it follows from the receptor pattern that the mixed beta1/beta2-blockade exhibits a substantially clearer effect.
