Pilot epidemiological studies in thrombosis.

Some differences in the blood of farmers in Nurmijarvi, Finland, Canino, Italy, and Beltsville, Maryland in the United States apparently were associated with differences, among the areas, in the farmers' diets. Those associations suggested that diets that are high in saturated fats (Nurmijarvi) could predispose humans to develop intravascular disease. Such predisposition has been observed in experimental animals. Low levels of the parameters that are considered active in such predisposition apparently were associated with diets that were low in saturated fats (Canino) or with diets that were low in saturated and high in unsaturated fats (Beltsville). Within the limits of the experimental design, the data from the three population groups indicated that a more comprehensive study might establish a relation between diet and intravascular disease in humans.

Intramuscular energy sources in dogs during physical work.

Three groups of dogs were run under different experimental conditions characterized by varying the work load or the running time. Lipid and glycogen analyses were carried out on biopsy specimens from the biceps femoris muscle before and after exercise. In addition, arterial and venous triglycerides and free fatty acids were determined on plasma samples from one group of dogs that had been previously catheterized. Under the conditions of these experiments, results revealed: (1) plasma triglycerides did not contribute significantly to the energy supply for muscle contraction; (2) plasma free fatty acid efflux into muscle was increased during mild exercise but significantly lowered during heavy exercise; (3) exercise did not affect the phospholipid level or its composition in the muscle; and (4) muscle triglyceride levels may increase, decrease, or remain unchanged, depending upon the work load imposed by the exercise.
