Salt intake in Ceylon

Sensing salt intake.

The long-term regulation of blood pressure rests on renal and nonrenal mechanisms and depends on a delicate balance between vasoconstrictor and vasodilator hormones and humoral agents, as well as those factors that act to increase or decrease renal sodium transport. Hypertension develops when this balance is disrupted and abnormalities in the regulation of ion transport intrinsic and extrinsic ...

Salt sensitivity in blacks. Salt intake and natriuretic substances.

Accumulating evidence suggests that hypertension in blacks is manifested in part by impaired renal excretion of salt. Consequently, this study was performed to determine if hypertensive and normotensive black subjects differ in their ability to generate known natriuretic substances. Fourteen normotensive and 11 hypertensive blacks were maintained on constant metabolic diets containing either 40...

Session VI. Factors in Reducing Salt Intake High Salt Intake Sensory and Behavioral Factors

Salt (NaCI) is a ubiquitous component of diets in developed countries. A major reason for this is that people judge many salted foods as more palatable than the same foods without salt Because recent evidence indicates that an acceptable salt substitute is unlikely, an understanding of the behavioral and sensory factors involved in maintaining high salt preference is a prerequisite to successfu...

Prehistoric Archreology in Ceylon

Pterygium in Ceylon.

The geographical situation of Ceylon led Cameron (I965) to suggest that the pterygium rate there would range from 5-5 to over io per cent., but the actual incidence appears to be much less for reasons which are discussed below. The incidence of pterygium has not been closely studied, first perhaps because it rarely causes blindness, secondly because the world's earliest eye hospitals were situa...
