| Summary: | Thesis (M.A.)--Boston University === Literature Review: The definition, history classification types, and possible etiological factors of hypertension have been review in detail. The theories of neurogenic origin, endocrine origin(including adrenal cortex, medulla. pituitary, thyroid, parathyroid, gonad, pancreas), and renal origin have been presented. The relationship between the various steroids produced by different endocrines is reviewed.
Material, Methods and Results: Heart weights of 500gms. in males or 450. gms females or more. were taken to indicate hypertension. Those weighing less than 400 gms. in males or 300 gms. in females were considered non-hypertensive. Blood pressure readings of 150/100 or more were considered hypertensive for any age and no case was accepted as normotensive controls if there was a record of a systolic pressure over 140 or diastolic pressure over 90 mgm. of mercury. All cases of valvular disease of the heart were discarded. [TRUNCATED]
