[Relation of urinary excretion of cholesterol in cancer patients to certain hormonal-metabolic parameters and the effect of drugs on this relation].

Excretion of cholesterol with urine was studied using gas chromatography in healthy persons, in patients with cancer of mammary glands, fibroadenoma, lung carcinoma and in patients with beningn processes in lungs. Cholesterol excretion was not increased in patients with the malignant tumors studied. In patients with the cancer of mammary glands and lung carcinoma normal correlation was altered between excretion of cholesterol with urine and content of lipoproteins, protein-bound iodine, 11-hydroxycorticosteroids in blood as well as excretion of cyclic AMP with urine. Treatment with euphylline was accompanied by a decrease in cholesteroluria in patients with fibroadenoma but the drug had no comparable effect on patients with the cancer of mammary glands. In patients with the cancer of mammary glands phenphormine caused distinct decrease and misclerone--moderate increase in excretion of cholesterol with urine.

Serum cortisol and 11 deoxycortisol by liquid chromatography: clinical studies and comparison with radioimmunoassay.

We describe a liquid-chromatographic procedure for separating and measuring cortisol and 11-deoxycortisol in serum. We quantitated these steroids in patients who were undergoing various tests of pituitary and (or) adrenal function and compared the results with those obtained by two radioimmunoassays done in two different laboratories. Results of 48 tests done in 37 functionally normal humans are presented. Cortisol values for sera collected in the morning as determined by liquid chromatography were (mean +/- SD) 134 +/- 54 micrograms/L. Serum cortisol concentrations increased from 136 +/- 65 to 321 +/- 80 micrograms/L 60 min after injecting synthetic corticotropin and increased from 107 +/- 46 to 242 +/- 31 micrograms/L after insulin-induced hypoglycemia. Serum cortisol decreased from 142 +/- 49 to 26 +/- 20 micrograms/L after oral administration of metyrapone, while 11-deoxycortisol increased from less than 10 to 210 +/- 53 micrograms/L. Serum cortisol measured less than 10 micrograms/L the morning after oral ingestion of dexamethasone. Results of the dynamic tests of adrenal function correlated well with previously reported studies. However, the cortisol values obtained by our technique were generally lower than those obtained by radioimmunoassay, possibly owing to lack of specificity of the latter methods used here for comparison. In contrast, values for 11-deoxycortisol were the same by both methods. The present studies confirm the usefulness of liquid chromatography for measuring these two steroids in serum during tests of pituitary and adrenal function. Future refinements of the technique should continue to increase its clinical applications.

[Post-operative hyperaldosteronism and related endocrine perturbations (author's transl)].

Electrolytes disturbances during operative period are believed to be related to an hyperaldosteronism produced by anaesthetic management and surgery. Effects of ethrane anaesthesia and surgery on hydroelectrolytic metabolism and endocrin function were investigated in 11 patients submitted to an abdominal surgery. Plasma and urinary levels of aldosterone were increased (x3) significantly (p less than or equal to 0.001) during operation, then decreased gradually in post-operative period, and return to normal values when Na/K ratio is reversed in urines. Relationship between hyperaldosteronism and other changes in endocrine function are established by determination of following hormones: A.C.T.H., cortisol, plasma renin activity (P.R.A.) catecholamines in plasma and urinary levels of 17-ceto, 17-hydroxysteroids and catecholamines. Ethrane anesthesia give a good neurovegetative stability since plasma catecholamines levels are not affected significatively. Plasma aldosterone level is correlated with urinary aldosterone and plasma renin activity. Plasma A.C.T.H. is much more increased at the operative time and decreases rapidly instead of plasma cortisol which decreases more slowly. Relationship of this hyperaldosteronism with anesthetic management, surgical stress intestinal transit disturbances, other endocrine function changes is discussed.

Juvenile nasopharyngeal angiofibroma.

A case of juvenile nasopharyngeal angiofibroma in a 14 year old boy is presented on account of the endocrinological investigation performed before, during, and after treatment with 15 mg/day diethylstilbestrol for more than one month. Previously, the tumor had recurred in spite of extensive surgery. Secondary sexual characteristics were normal and the development of puberty at the age of 12-13 years seemed not to have influenced tumor growth. In contrast to certain previous reports, normal functions were found regarding the pituitary, the gonads, the adrenal cortex, and the thyroid gland in our patient. The tumor continued to grow in spite of the diethylstilbestrol therapy.

[Hormone and mediator content in the blood of the adrenals and in the peripheral blood in hypertension].

The concentration of the fractions of corticosteroids, aldosterone, catecholamines, and cyclic nucleotides (cAMP and cGMP) in blood of the adrenal veins and the activity of renin in blood of the renal veins were studied in 22 patients with stages IIA and IIB hypertensive disease. At the same time the content of these substances in the peripheral blood was determined and compared with the level of steroid and catecholamine excretion in the daily urine. An increase in the content of free 11 OCS and F fractions in the peripheral blood and blood of the adrenal veins was revealed in all patients examined.

[Serum neuraminic acid level in patients with cerebrovascular disorders].

The authors determined the level of neuraminic acid in the serum of 50 patients with encephalomalacia and 25 patients with cerebral haemorrhages on the 1st, 3d and 7th days of the disease. Twenty healthy subjects served as controls. A statistically significant rise in the concentration of this substance was observed in both groups of patients throughout the whole period of observations.
