[A study on enoxacin concentration in human prostatic tissue].

To examine the penetration of enoxacin into prostatic tissue of patients with benign prostatic hypertropHy, the serum concentration and prostatic tissue level of enoxacin were measured. Enoxacin was administered orally at a dose of 200 mg, three times 2 days and one day before and once on the day of the operation. Blood and prostatic tissue samples were taken during the operation. The mean concentration of enoxacin was 2.84 +/- 0.349 g/ml in serum and 4.60 +/- 0.631 micrograms/ml in the prostatic tissue.

Prophylaxis of superficial bladder cancer with instillation of adriamycin or mitomycin C.

A multicenter trial for postoperative prophylaxis of superficial Ta-T1, G1-G2 bladder cancer was performed. Intravesical instillation using either 20-30 mg adriamycin or 20 mg mitomycin C per dose was carried out for 4 weeks or 2 years. Patients without instillation served as controls. A total of 259 patients was considered eligible for the evaluation. The instillation group showed a better disease free survival rate than the control group. Better prophylactic effects of instillation therapy were observed when one of following factors was present: multiple tumors, large tumors, T1 and G2 bladder cancer. The total dose of drug instilled seemed to correlate with the effects, but there were no differences between adriamycin and mitomycin C. The side effects were minimal and temporary.

Changes in the volume and histology of retractile testes in prepubertal boys.

Testicular development was studied in prepubertal boys with retractile testes. Testicular volume, the diameter of the seminiferous tubules and the number of spermatogonia in the tubules were decreased in cases of unilateral retractile testis, when compared with values for the contralateral normally descended testis. On the other hand, in patients with a unilateral retractile testis and contralateral inguinal testis, there was no difference in the developmental parameters between the two testes. These results suggest that the retractile testis has developmental failures characteristic of a cryptorchid testis and therefore requires orchiopexy.

[Percutaneous transluminal angioplasty].

Percutaneous transluminal angioplasty (PTA) was done in a 58-year-old man with hypertension due to a left-sided renal artery stenosis. Hypertension was cured dramatically and plasma renin activity was within the normal range after the operation. This non-traumatic procedure seems to be excellent and recommendable as a first treatment of renovascular hypertension.

[A case of congenital adrenogenital syndrome].

A 52-year-old woman was admitted, complaining of an abdominal mass and jaundice. The abdominal mass was revealed to be myoma uteri. We explored her hormonal data for her virilizing signs. Urinary 17KS and pregnanetriol levels were elevated and decreased by cortisol administration. She was diagnosed to have 21-hydroxylase deficiency and has been well controlled at our out-patient clinic.

[gamma-Seminoprotein in serum of prostatic cancer].

From August, 1981 to May, 1984, we measured gamma-seminoprotein in the serum of 51 untreated patients with prostatic cancer in the Chiba University Hospital. Prostatic acid phosphatase (radioimmunoassay) in serum was also measured in these patients. We also measured gamma-seminoprotein and prostatic acid phosphatase in serum of patients under control by hormonal treatment and of reactivated patients. In untreated stage B and stage C cases, positive rate of gamma-seminoprotein in serum was larger than that of prostatic acid phosphatase. Therefore the measurement of gamma-seminoprotein in serum is considered to be useful in the diagnosis of early prostatic cancer. Four weeks after hormonal treatment, gamma-seminoprotein in the serum of 74% of the patients returned to the normal level. The positive rate of gamma-seminoprotein in the serum of reactivated patients is significantly larger than that of the patients under control by hormonal therapy.

Indomethacin suppresses prolactin release in men.

Indomethacin administered intrarectally at a dose of 100 mg elicited a statistically significant decrease of serum prolactin level in men. Serum LH level was depressed slightly but the decrease was not statistically significant. There was no effect on serum FSH concentration.
