    Notes: [Auszug] RELATIVE to other mammals, the volume of digestive secretions in ruminants is large. This is mainly because of the large continuous alkaline salivary secretion1-3 which buffers the acid products of microbial fermentation in the rumen. In sheep and goats the daily salivary secretion of 10-15 1. ...

    Notes: [Auszug] Myoglobin was isolated from the skeletal muscle of sperm whale by the procedure of Perkoff and Tylor4 and crystallized twice by the method of Luginbuhl5. Spectral analysis of these preparations showed that the myoglobin was in the ferri- or met- form. Thin was also observed by Perkoff et al.G for ...

    Notes: [Auszug] Investigation of the activation of Factor X suggests a parallel with the activation of prothrombin (Factor II), and may provide a model for the whole mechanism. It-was found that the coagulant effect of Russell's viper venom is due to its specific action on Factor X to form a product which, with ...
