The Pharmacology of Hypophyseal Extracts 



FREDERICK S. HAMMETT 



1. Showing the drop in arterial pressure induced by the injection of an 



extract of the anterior lobe of the hypophysis 745 



2. To show the effect upon the blood-pressure of the rabbit following the 



intravenous injection of pure pars intermedia extract 747 



3. Showing the oxytocic effect of posterior lobe extract on the uterus in 



situ and the similar type of response induced by histamine . . . 753 



4. Graph showing concordant results obtained from the application of 



repeated doses of an equal amount of pituitary extract to the isolated 

 uterus of the virgin guinea-pig 754 



5. The constrictor and the relaxing effect on the isolated loop of the in- 



testine of a posterior lobe preparation 756 



fi. Tracings which demonstrate the effect of the administration of 0.9cc. 

 of a 1.25 dilution of posterior lobe extract on the blood-pressure and 



respiratory movements 757 



7. A diagram showing the antidiuretic action of 2 cc. of pituitrin intra- 

 venously injected into a rabbit in which artificial polyura had been 

 induced by copious water administration . 761
