Abstract

Both the adenylate cyclase activity and the motility of human sperm were stimulated by bicarbonate with the same concentration dependency. The correlation between bicarbonate levels in semen and the motility of sperm from the patients with male infertility was investigated. Bicarbonate in semen was found to originate mainly from the seminal vesicles, and a significant positive correlation was observed between bicarbonate levels and volume of semen. The motility of infertile sperm was also found to correlate positively to the seminal levels of bicarbonate. These results suggest that the lowered levels of bicarbonate in semen are at least in part responsible for the poor sperm motility in infertile patients, as a result of the failure in the activation of sperm adenylate cyclase.

Abstract

Plasma erythropoietin levels were determined by Keighley's method to study the changes in erythropoiesis before and after human renal homotransplantation. Results. Erythropoietin titres in pre-transplant patients were low, while they returned to normal after successful renal transplantation. In acute rejection they were significantly high. After its reversal normal levels of erythropoietin were obtained in accordance with a normalization of the graft functions. Reticulocyte counts paralleled with erythropoietin values. Conclusion. High levels of plasma erythropoietin contribute to the diagnosis of acute rejection. Normalization of the plasma erythropoietin levels after the acute rejection could be regarded as an indication for good function of the graft. The grafted kidneys seem to function in producing erythropoietin.
