F"iG. 28. — The relation of the pituitary body to hypertension caused by renal 

 ischemia following the application of Goldblatt's clamp to the renal arteries. (From 

 Page and Sweet, Amer. J. Physiol., 120, 238-45 [1937].) 



Ordinate: arterial blood pressure; abscissa: time in days. Without hypophy- 

 sectomy, the hypertension following the application of the first clamp probably 

 would have persisted some months. Hypertension subsequently produced by 

 tightening the right and left clamps was transient. The administration of thyroid 

 gland in other experiments caused a recurrence of the hypertension.
