Abstract:
Kallikrein activity was measured in urine, saliva and blood plasma samples from pregnant cows by using the chromogenic substrates S-2266 and S-2302 (Kabi, Sweden). It was found that the kallikrein activity in these biological fluids showed a trend to an increase with a peak prior to parturition. At the same time the plasma prekallikrein levels decreased during pregnancy reaching the lowest values at the end of the gestation period.
