ABSTRACT
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. In addition, Streptococcus agalactiae was identified in blood cultures. The patient underwent surgical resection of the vegetation followed by tricuspid valve repair including De Vega's annuloplasty. Antibiotic therapy was continued for 4 weeks after surgery, and he was discharged on the 31st postoperative day. No endocarditis nor tricuspid valve dysfunction has re-occurred.

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. The high-protein diet decreased the amplitude of feed intake under zinc deficiency, probably because of a decrease in sensitivity to the deficiency. Furthermore, the zinc-deficient diet was supplemented with essential amino acids, and of them L-threonine showed the most marked effect on the increased variability of feed intake.
