Rats were fed for 24 days a liquid diet with ethanol as 36% of calories to produce hyperlipemia and hepatic steatosis. The catabolism of chylomicrons doubly-labeled in the triacylglycerol and cholesteryl ester moieties was studied in conscious rats after ingestion of their usual liquid diets with or without ethanol. A constant intravenous infusion of chylomicrons revealed a defect in chylomicron catabolism after chronic treatment with ethanol. The plasma clearance of chylomicron cholesteryl ester was impaired to a greater extent than clearance of chylomicron triacylglycerol. These findings are consistent with defective catabolism of chylomicron remnants, and suggest that the accumulation of chylomicron remnants in the plasma contributes to the development of increased post-prandial hyperlipemia and chronic hyperlipemia in association with excessive ethanol consumption.

In an ongoing study 558 consecutive survivors of myocardial infarction below 70 years, mean age 59 years, were randomly allocated 4 months after the acute episode into a control group or a chemotherapy group from December 1972 to April 1976. Both groups were given moderate advice about diet and the chemotherapy group was prescribed clofibrate, 1 g twice daily, and nicotinic acid 1 g three times daily. Serum cholesterol and triglycerides were lowered around 15-20% and 30% respectively in the chemotherapy group while only insignificant reductions were observed in the control group. Until December 1976 total mortality and mortality from IHD has been the same in the two groups. The number of non-fatal myocardial infarctions has been 38 in the control and 19 in the chemotherapy group, a statistically significant reduction (P less than 0.01).

The triglyceride fatty acid pattern (TFAP) in arterial wall, adipose tissue and serum in vivo has been estimated in amputated diabetic subjects by gas-liquid chromatography simultaneously. Besides, in some probands the fatty acid pattern of cholesterol esters of vessel walls has been obtained. In arterial wall the percental content of lauric, myristic, myristoleic, palmitoleic, stearic, oleic and linolenic acid was high and that of palmitic and linoleic acid was low, when compared to serum, whereas eicosatrienoic, arachidonic and eicosapentaenoic acid were of similar magnitude. In comparison to adipose tissue myristic, palmitic and nervonic acid were decreased and eicosatrienoic, arachidonic and eicosapentaenoic acid were increased in arterial wall. In view of the results the speculation is obvious that certain fatty acids have distinct metabolic positions in several tissues, such as depot fatty acids and precursors of prostaglandins, for example.

In fourty patients with peripheric atherosclerosis obliterans blood flow was measured by means of venous occlusion plethysmography during an intraarterial and an intravenous infusion of ATP. The intraarterial application showed a significantly higher increase of blood flow than the intravenous in the sick extremities. The "borrowing-lending-phenomenon" happened more seldom than after an intravenous load. This withdrawal of blood occurred most frequently in patients with proximal occlusions, when the infusion reached casually the arteria femoralis profunda only. The "borrowing-lending-phenomenon" can be measured by the poststenotic pressure and by the volume of blood flow in time. Then the patients complain about a begining or an increasing of an ischemic pain at rest.

The coronary arteries were examined in 60 specimens from patients with mitral stenosis. In three, localized obstruction was nonatherosclerotic in nature (in one, arterial dysplasia; in two, embolic). In 18 of the remaining 57 cases (31.5%), significantly obstructive atherosclerosis in one or more segments of the coronary arterial system was found. This represented 46% of the males and 27% of the females. The incidence of involvement of three or more arteries by significantly obstructive atherosclerosis was 39%, while in a cited series of subjects with angina pectoris three or more vessels were involved in 79% of the cases. It may be concluded that, on the average, the distribution of lesions in patients with mitral stenosis and significant coronary atherosclerosis is less wide than in subjects with clinical coronary disease.

The postmortem study of a classic case of Werner's syndrome is presented. The subject was a Japanese man who died at the age of 39. Major findings included general microsplanchnia, extreme atrophy of the testes and skin, calcified aortic atherosclerosis, an increase of basophils in the pituitary, aspiration pneumonia, chronic pyelonephritis and a meningioma in the occipital area of the brain. Histologically, no osteoporosis was evident in the lumbar spine and iliac bone. The findings suggest that in Werner's syndrome the dominant pathologic factor may be found in connective tissue other than bone.

Although the diagnosis of hyperlipidemia is somewhat arbitrary, in that the upper limits of normal are not universally agreed upon, it is clear that the risk of atherosclerosis increases with plasma cholesterol concentration; it may also increase in hyperglyceridemia. We take 220 mg/100 ml as the upper limit of normal for plasma cholesterol and 140 mg/100 ml as the upper limit for triglycerides. Treatment of hyperlipidemia is aimed at reducing the risk of atherosclerosis or arresting its course. Alteration of diet is the first step. If maximal diet therapy does not lower plasma lipids to acceptable levels, drug therapy is added. The decision to treat hyperlipidemia with drugs should be based on a careful weighing of risk vs. benefit for each patient. Because of the rapid change in our knowledge of both the risks and the benefits of therapy, that decision must be reviewed and updated at regular intervals.

This study of 24 women under age 40 years with myocardial infarction demonstrates that even in young women myocardial infarction is most commonly due to coronary atherosclerotic heart disease. Other causes of coronary occlusion were documented in 17% of these patients, indicating that these lesser causes of myocardial infarction are more common in young women than in older persons or in young men. In those patients with coronary atherosclerosis one or more significant risk factors could usually, but not always, be documented. The clinical manifestation of the coronary occlusion in the study group was not unlike its manifestation in groups of different ages or sex, or both.

The water flux through preparations of porcine aorta has been investigated. After an initial unsteady period a stable flux of approximately 2 mul/cm2-h was reached and this flux rate remained constant for several hours. Under the experimental conditions which were maintained (110 mm Hg pressure drop across a 2 mm thick section of tissue) this total flux corresponds to a hydraulic conductivity of less than or equal to 7.0 X 10(-13) cm4/dyne-sec. Since these data were obtained in tissue samples where the endothelial layer was not intact, they represent values which are in fact larger than the actual in vivo condition where the endothelial barrier would serve as an additional resistance. Thus, they demonstrate that the transmural flux of water across the aorta wall in vitro due to a pressure gradient is extremely small and, therefore, that other mass transfer mechanisms may be significant.
