Forty patients over 70 years old with a diastolic blood pressure of 95 to 110 mm Hg and/or a systolic blood pressure of 170 to 220 mm Hg after two weeks' placebo therapy underwent a single-blind, placebo-controlled, randomized cross-over study using captopril and triamterene and hydrochlorothiazide (Dyazide). Blood pressure was lowered from a mean of 189 +/- 2.0/92 +/- 1.7 mm Hg (mean +/- SEM) to 161 +/- 2.8/78 +/- 1.7 mm Hg with captopril therapy, and therapy with triamterene and hydrochlorothiazide produced similar reductions (156 +/- 2.7/78 +/- 1.7 mm Hg). Two patients on triamterene and hydrochlorothiazide therapy withdrew because of side effects, while only minor side effects were observed with captopril therapy. Therapy with triamterene and hydrochlorothiazide produced significant elevation of urea, creatinine, and uric acid, while captopril therapy produced no biochemical or hematologic changes. A single daily dose of captopril alone was sufficient to normalize the blood pressure in 31 (75%) of 40 patients. Captopril appears to be a promising monotherapy for the elderly with mild to moderate hypertension.

Influence of hepatic arterial infusion with degradable starch microspheres (DSM) or with anti-cancer drug or with both for normal liver regeneration in rat was determined by histological and microautoradiographical examination and liquid scintilation before or after 70% hepatectomy. DSM was seen in interlobular artery in early phase after hepatic arterial infusion, but disappeared into the central vein by degrees for 2 hours later. Adriamycin (ADM) in serum was detected for a long time after hepatic arterial infusion with DSM + ADM. In the heart muscle, a significantly lower concentration of ADM was seen in the DSM + ADM group than in the ADM only group. In the case of hepatic arterial infusion with DSM only after hepatectomy, there was no influence on normal liver regeneration. No significant difference was seen between hepatic arterial infusion and intravenous infusion with ADM only. However, in the case of hepatic arterial infusion with DSM + ADM after hepatectomy, a significant difference was seen in the inhibition of liver regeneration from any other groups.

A case of Fabry's disease with pulmonary regurgitation is reported, and the cause of valvular involvement, the electrophysiological mechanism of the short PR interval, and the usefulness of the endomyocardial biopsy method in an attempt to establish the diagnosis in Fabry's disease have been discussed.

A 78 year old, right handed man developed the syndrome of alexia without agraphia due to a right occipital thrombotic stroke. The cerebral dominance test strongly suggests that his right hemisphere is dominant. This is believed to be the first case of alexia without agraphia secondary to a right occipital lesion in a right handed person.
