[Tricuspid Valve Repair in a Patient with Isolated Tricuspid Valve Infective Endocarditis with Pulmonary Embolism;Report of a Case].

We report a case of 39-year-old man who developed tricuspid valve infective endocarditis with a complication of pulmonary embolism. He was transferred to our institution because of intermittent fever and enlargement of the vegetation of the tricuspid valve in spite of optimal antibiotics treatment. Computed tomography revealed pulmonary embolism, and transesophageal echocardiography showed a large and mobile vegetation (22×10 mm) on the tricuspid valve with moderate regurgitation.

L-threonine supplementation increases the amplitude of the feed intake cycle of rats fed a low-protein zinc-deficient diet.

Rats fed a Zn-deficient diet show characteristic variations in feed intake. These variations were followed by means of a personal computer. The specific feed intake patterns in rats fed a zinc-deficient diet before and after supplementation with protein and several essential amino acids were determined.
