Morphologic spectrum of liver diseases among chronic alcoholics. A comparison between Tokyo, Japan and Cincinnati, U.S.A.

To deliniate the histopathological features of liver diseases seen in Japanese alcoholics, 130 Japanese alcoholic patients were studied in comparison with 238 American alcoholic patients. In Japan female alcoholic patients were extremely rare. The male to female ratio was 127 to 3 in Japan and 152 to 89 in U.S.A. Although all aspects of alcoholic liver disease did exist in Japan, typical cases of acute alcoholic hepatitis with alcholic hyalins were remarkably smaller in number (9.2% in Japan versus 39.5% in the U.S.A.). The severity based on histopathological findings was also less in the Japanese cases. In contrast to this, 46 percent of Japanese alcoholic patients had chronic hepatitis, and the incidence of multilobular cirrhosis was much greater in Japan wherewith higher prevalence of viral hepatitides.

The effect of vitamin D2 on hypocalcemia in patients under chronic hemodialysis.

The effects of vitamin D2 (VD2) on hypocalcemia were studied in 54 hypocalcemic patients (29 males and 25 females) on chronic hemodialysis. Calcium lactate (3 g/day) or VD2 (10,000 IU/day, 50,000 IU/day and 80,000 IU/day) were administered for 4 months in order to correct the hypocalcemia. Serum calcium, phosphate and alkaline phosphatase levels were measured and the effects of VD2 on these parameters of calcium metabolism were followed. 1) Calcium lactate or 10,000 IU/day of VD2 were not effective for the correction of hypocalcemia, while 50,000-80,000 IU/day of VD2 were effective. The effects of VD2 on serum calcium concentrations were dose-dependent, and the normalization of serum calcium concentrations was achieved more rapidly with higher doses of VD2. However, in the group treated with 80,000 IU/day of VD2, many patients developed hypercalcemia, but in the group treated with 50,000 IU/day of VD2, only a few patients did it. From these results, suitable dose (initial and maintenance doses) of VD2 in dialysed patients would be 50,000 IU/day. 2) When the responder group (normal serum calcium levels after 4 months of treatment with 50,000 IU/day of VD2) and the non-responder group serum calcium levels lower than 4.2 mEq/liter on the same condition) were compared, the durations of dialysis were significantly shorter in the former than those in the latter. This fact may suggest that the effects of VD2 administration on hypocalcemia in dialysed patients are partly dependent on the residual renal function concerning the conversion of 25-OH-D3 into 1,25 (OH)2D3.

Semiquantitative evaluation of ophthalmic collateral flow in carotid artery occlusion: ultrasonic doppler study.

The reliability of quantitative evaluation by doppler ultrasound with regard to the ophthalmic collateral blood flow in patients with carotid artery occlusion was estimated. The ultrasonic doppler flow signals of the ophthalmic collateral flow of 54 carotid occlusions were classified into four types and three degrees--high, moderate, and low reversed flow patterns--and were compared with the angiographic findings of the collateral flow classified into three grades--good, poor, and none. With the exception of three cases, the ultrasonic doppler flow patterns of the collateral flow correlated well with the angiographic findings in 54 occluded carotid arteries.

Factors influencing the release of renin in patients under chronic dialysis treatment.

Plasma renin activities (resting PRA, post-dialysis delta PRA) were studied in 61 patients under chronic dialysis treatment. Removed sodium and removed water were estimated at each dialysis. Delta PRA/removed-sodium and delta PRA/removed-water were calculated as indices in response to the removal of sodium and water during the dialysis. 1)Resting PRA (pre-dialysis PRA) was positively correlated to delta PRA/removed-sodium, delta PRA/removed-water, serum osmolality, and diastolic blood pressure, but negatively to serum sodium concentration, age, and pulse pressure/diastolic blood pressure. Statistically significant factors controlling the resting PRA were delta PRA/removed-sodium, delta PRA//removed-water, and serum sodium concentration. Resting PRA was slightly correlated to diastolic blood pressure and age. 2)Post-dialysis PRA was significantly correlated to the resting PRA, delta PRA/removed-sodium, delta PRA/removed-water, serum sodium concentration, and age, but not to the blood pressure indices.
