[The effect of thrombocytapheresis on hematologic, biochemical and immunologic indicators].

The authors investigated in 33 separate donors the influence of thrombocytapheresis on haematological, biochemical and some immunological parameters. The paired t-test revealed a statistically significant increase of values of total proteins, aspartate aminotransferase, immunoglobulin A, alpha 1 antitrypsin, transferrin and the C4 component of complement seven days after apheresis and a significant increase of thrombocyte, total protein, alkaline phosphatase, immunoglobulin A, orosomucoid, and transferrin levels two weeks after apheresis. A significant decrease of haemoglobin values was recorded 7 and 14 days after apheresis.

[Hormonal contraception and levels of selected serum proteins].

The authors investigated 116 women who took hormonal contraceptives. All women were subjected to detailed clinical and biochemical examinations. In the serum a number of biochemical and immunological tests was made.
