In one study volunteers consumed the equivalent of at least a six-pack of beer a day, along with high protein diets enriched in minerals and vitamins. After one "weekend" of drinking, fat accumulation in the liver was already detectable by chemical analysis. In another study, baboons were given an adequate diet, but had alcohol as 50 percent of their total calories. All developed fatty liver. I...

Sixteen patients with refractory hypertension were submitted to vigorous sodium depletion while cardiovascular homeostasis was monitored with measurements of hormonal and hemodynamic parameters and repeat saralasin tests. This regimen resulted in a negative sodium balance by an average of 300 mEq. The loss of sodium closely correlated to the decrease of body weight (r = 0.70, p less than 0.005)...

Effects of MCI-176, 2-(2,5-dimethoxyphenylmethyl)-3-(2-dimethylaminoethyl)-6-isopropox y-4 (3H)-quinazolinone hydrochloride, on coronary and aortic blood flows, mean blood pressure and heart rate were investigated in comparison with those of diltiazem in anesthetized dogs. MCI-176, like diltiazem, dose-dependently increased coronary and aortic blood flows and decreased mean blood pressure. In p...

A 31-year-old HIV-positive Hispanic man with a history of intravenous drug abuse was admitted with sudden onset, sharp, bilateral chest pain with shortness of breath. The pain was predominantly in the posterior thorax and was not pleuritic in nature. The patient also reported fevers to 39.0#{176}Cfor two days prior to admission. In the more distant past, the patient described a cough productive...

A 24-hour urine collection for 5-hydroxyindoleacetic acid (HIAA) is commonly performed to evaluate patients with suspected carcinoid syndrome. However, carcinoids are rare, and elevated results are common even when using an analytically specific method. To characterize this problem, the incidence of elevated results was examined in a population of 947 patient specimens received in a clinical re...
