Renin and Antirenin in Treatment of Long Term Experimental Renal Hypertension in the Dog.

Abstract
Courses of intramuscular injections of semipurified hog renin from cortex given to dogs with experimental renal hypertensions of 4 or more years duration produced a significant reduction in blood pressure in those dogs which developed antirenin but not to normotension. Passive immunization with homologous antirenin to hog renin produced a reduction in blood pressure to normotension or near normotension in dogs with experimental renal hypertensions of more than 7 years duration. Results indicate that renin (or a closely related renal protein) is the principal pathogenetic factor even in experimental renal hypertension of many years duration in the dog.
