[Testosterone, FSH and LH level in the serum of patients with prostatic neoplasms, treated with female hormones].

Testosterone, FSH and LH were measured in serum of patients suffering from prostatic carcinoma. The efficacy of treatment with 1 mg diethylstilbestrol/d (Cyren A) was shown by suppressed serum levels of testosterone, FSH and LH comparable to castration in a follow-up until 560 weeks after beginning of therapy. Prolactin was raised in all patients under treatment.

Denudation of the urinary bladder mucosa in the cat by formaldehyde.

Chemical Stripping of the urinary bladder mucosa was studied in 38 cats using 5 to 25% formaldehyde solutions. The contact time varied from 1 to 20 min. With a 20% solution and contact time of 1 min, total denudation was possible without necrosis of subepithelial layers. In such cases, complete reepithelialisation and normal bladder dynamics were seen within 3-4 weeks after formaldehyde instillation. Signs of formaldehyde intoxication due to vesical resorption were not observed.

Replacement of urinary bladder wall in the cat by autologous x-ray treated full thickness skin graft.

A partial urinary bladder resection was performed in 25 female cats. The defect was replaced with an X-ray treated autologous full thickness skin graft. This graft was shown to be an appropriate foundation for the rapid regeneration of transitional cell epithelium which was proven to be present after 4 weeks. Smooth muscle fibres were present in all cases after 12 weeks. Postoperatively, bladder capacity was adequate without evidence of incrustation or ossification. No changes were seen in the upper urinary tract. Compared to other types of autologous bladder wall replacement this method is simple and warrants clinical investigation.

[Cytological examination for determining the therapeutic response of prostatic carcinoma to hormonal therapy (author's transl)].

51 patients with proven prostatic carcinoma stage B-D underwent control aspiration biopsy after hormonal therapy using the Franzén needle. The malignancies were classified into three grades and the cytological findings were compared with the malignancy grade of the tumor and the clinical course. At the same time the caryopycnotic index, as determined by swabs from the urethral fossa navicularis was measured in order to determine the serum estrogen level. As the result of the anti-androgenic therapy one finds degenerative changes in the tumor cells. The results showed that the poorer the histological differentiation of the tumor, the lesser was the cytological change. Only 6 of 34 patients with a good hormonal effect showed a progression of the tumor, whereas 16 of 17 patients with a poor hormonal effect showed clinical progression. 70% of the cases demonstrated agreement between the clinical course and the caryopycnotic index. No correlation was found between the caryopycnotic index and the histological grade of the tumor.

[Varicocele as a cause of disorder in fertility (author's transl)].

In this study the pathophysiological connections in varicocele genesis are discussed, as well as its effect upon spermiogenesis and the causal factors. In 73 patients the high retroperitoneal ligature of the testicular vein was performed. Indication was given either on the basis of subjective complaints or on the proof of subfertility. In 79% of the cases a good anatomic result was obtained after operation. Of the spermiograms established prior to operation 56% showed postoperatively a distinct improvement in quality. In 52% of the sterile marriages conception occurred following operative intervention. In our clinic the operative method according to Bernardi is preferred, since it meets best the criteria of an ideal varicocelectomy. Operative intervention should take place early for possible preventing of spermiogenetic lesion.
