[Thrombophoresis II. Effects of thrombocyte separation on the blood donor (author's transl)].

The separation of approximately 75% of the platelets present in circulation and thrombocyte pool in healthy adult donors by continuous flow centrifugation lowers the mean thrombocyte concentration to 140 +/- 28 X 10(3)/microliter. A dangerous thrombocytopenia can not occur since the platelet count in the reinfused erythrocyte zone remains at around 88 X 10(3)/microliter. The reactive rise of the platelet count after separation, the extend of which depended on the total amount of harvested thrombocytes, reached values around 277 X 10(3)/microliter. The total thrombocyte yield exceeded the calculated yield by 30%, indicating emptying of a quiescent thrombocyte pool. Thrombopoietin activity could be demonstrated in donors' plasma at 12 and 24 hours after thrombophoresis.

Bias of the cover test in the diagnosis of alternating tropia.

In the evaluation of patients with alternating tropia, all errors tends to falsely overclassify the fixation pattern as free alternation and underestimate monocular fixation. This bias is particularly undesirable in infants when the cover test is used because more direct measurements of visual acuity are not possible.
