Serum calcium and blood pressure in Greek girls.

In a random sample of 492 girls 12-15-years-old total serum calcium appeared to be correlated with blood pressure. Adolescents with total serum calcium equal to a greater than the cohort mean (2.5 mmol/l) had higher systolic blood pressures than those with a value below the cohort mean.

Table salt and blood pressure in Greek children.

The habit of adding table salt was studied in a random sample of 2209 children 6-18 years old. Of these 10% routinely added table salt to prepared food before tasting it (group A), 29% after tasting it (group B) and 61% ate their food as it was prepared, without additional use of table salt (group C). Group A had higher blood pressure (BP), prevalence of systolic BP greater than or equal to 130 mmHG and body mass index (BMI) than groups B and C (P less than 0.

The effects of bilateral adrenalectomy on the fine structure of the rat myocardium.

The subcellular effects of bilateral adrenalectomy on the rat myocardium were examined on 50 male rats. The animals, divided into groups of ten, were killed 3, 17, 18, 19 and 21 after adrenalectomy. The early changes consisted of moderate intracellular edema of many cardiac muscle cells and disarrangement of their myofibrils.
