[Clinical studies on gentamicin in complicated urinary tract infections (author's transl)].

Twenty cases with complicated urinary tract infections were treated with gentamicin. Good results were obtained in 7 of 14 cases with chronic pyelonephritis and 2 of 4 cases with chronic cystitis and in 1 of 2 cases with acute prostatitis. No side effect was observed throughout this treatment. But in laboratory examination, slight elevation of S-GOT and S-GPT was observed in 3 of 20 cases after gentamicin treatment.

The effect of neutrophil depletion on reperfusion arrhythmias during intracoronary thrombolysis using the leukocyte removal filter.

To evaluate the effects of neutrophil depletion on reperfusion arrhythmias using a leukocyte removal filter (LRF), the authors examined several cardiovascular variables in three patients with myocardial infarction who underwent successful thrombolytic therapy with LRF compared with control patients without LRF. Coronary angiography performed within 4 hr of onset revealed total occlusion in the proximal segment of the left anterior descending (LAD) coronary artery, without collaterals, in all patients. Thrombolysis was performed by intracoronary administration of urokinase (10,000 IU/ml, 1,000,000 IU total) mixed with filtered autologous blood. LRF was composed of a nonwoven polyester fabric (1.8 microns, 4.6 g). Removal rates of leukocytes and platelets by LRF were 98-100% and 98%, respectively. Average duration of the ischemic episodes, maximum ST segment elevation, and integral of T segment depression did not differ in the two groups. However, the frequency of ventricular premature beats (VPB) during the first 30 min after reperfusion were significantly lower in the LRF treatment group (3.8%) compared with the control group (10.7%). Segmental shortening, measured by echocardiography one hour after recanalization, exhibited higher values in the LRF treated patients than control patients, without significant difference. Data suggested that LRF is effective in reducing reperfusion arrhythmias during intracoronary thrombolysis and activated neutrophils may play an important role in stunned myocardium.

Cold-induced ascites in broiler chickens and its improvement by temperature-controlled rearing.

Pulmonary hypertension syndrome (PHS), also known as ascites, in broiler chickens prevailed in the local area of Ibaraki prefecture, Japan, and was investigated epidemiologically, serologically, and pathologically. PHS developed in chickens older than 35 days of age when rapid increase of body weight started. Approximately 90% of affected birds were males, in which weight increase was greater than in females. Serologic test revealed that PHS broilers had an increase of hematocrit value. Pathologic studies indicated that the heart of affected birds had an obese-induced pressure and cold exposure triggered congestion in the right ventricle/cava and an increase in peritoneal fluid. These changes were consistent with the previous reports of PHS, so we designed the experiment of effects on cold-induced PHS birds in a temperature-controlled house. After the 10 PHS birds at 55 days were reared for 14 days in a temperature-controlled house at 20 +/- 5 C, ascites disappeared in eight birds and hematocrit values decreased to normal range in nine birds. Our finding indicated that temperature-controlled environment may be one solution to reduce mortality in PHS birds.
