Zur Frage der Begleitstoffe in gonadotropen Hormonpräparaten

Summary

Substances obtained from urinary extracts were investigated for their inhibitory effect on virus hemagglutination (Hirst), and a comparison was made with the gonadotropic hormone activity of these substances. No clear-cut parallelity between these characteristics was demonstrable. An urinary extract substance was further tested both prior to and subsequent to contact with the virus receptor destroying enzyme (R.D.E.), for the three established properties, hormonal activity, leucocytotactic effect and influenza-virus-receptor characteristics. R.D.E. did not affect these three properties to the same degree. These results support the assumption that urinary extracts represent a mixture of chemically closely related substances.
