JOURNAL FREE ACCESSFrom the clinical standpoint series of experiments were undertaken to determine the best method for assay of urinary gonadotrophine.
Alcohol precipitation method may be said to be a method of standard, because the yield of gonadotrophine does not fluctuate from case to case.
Kaolin adsorption method is a method of choice for the clinical purpose, while aluminium hydroxide adsorption method is not recommeneded owing to the less yield of gonadotrophine and some unconveniences during the process of extraction.
Acetone revealed to be available for precipitation of gonadotrophine to the same extent of alcohol.
Friedman's method was satisfactorily applied to determine the elevation of urinary gonadotrophine in cases of the primary testicular insufficiency.
Gonadotrophine-titre in the urine of normal male adults and some patients suffering gonadal insufficiency was estimated using the acetone precipitation method.
The author want to emphasize that the assay of urinary gonadotrophine is extremely important to make the diagnosis of male gonadal insufficiency as well as the testicular biopsy.View full abstractDownload PDF (4935K) -

JOURNAL FREE ACCESSThis is a study on the influence of the vasectomy in albino rats by histological, biochemical and histochemical examinations.
1) Histologically, there was little change in the spermatospare, spermatocyte and sertoli cell after a vasectomy. However, the development of sperma from spermatid was impeded. This phenomenon increased gradually after the operation for 8 to 12 weeks, but reduced 20 weeks after the operation.
In the interstitial tissue the roughness and edema of connective tissue, and the proliferation of interstitial cells were observed nearly parallel to the change in the spermatogenesis.
2) An enlargement of the gland cavity and an increase of gland contents were recognized in epididymis. A hypertrophy of the epithelial cell in spermatic cord, and a constriction of the gland cavity in seminal vesicle and prostate, were also recognized.
3) Changes in the young albino rats were almost the same as the changes in mature animals, though the changes were apt to be slightly milder in the former. In young animals the testis fully developed with the general maturity even after the surgery.
4) When the testosterone propionate is given to mature rats after the vasectomy, the spermatogenesis is more definitely inpeded than in those with simple vesectomy.
5) The ligature and cutting of circumferential tissue with the spermatic cord, caused an atrophy of the testis of the same side in the majority of rats.
6) In the histochemical and biochemical observations, the slight lowering of Alkali-Phosphatase activity of seminiferous tubule and the slight rise of β-Glucuronidase activity of seminal vesicle were seen in the mature rats after the vasectomy.
In young animals there was a rise of β-Glucuronidase activity of testis but no definite change in the lipase and esterase.
No definite changes were observed neither in the accessory sexual gland nor in other organs.View full abstractDownload PDF (10133K) -

JOURNAL FREE ACCESSThere are many reports of various tumors in the retroperitoneal cavity, and the description of retroperitoneal lipoma by Morgani (1761) may be the first one in this disease group. In 1829 Lobstein first proposed a disease “retroperitoneal tumor”, which generates at retroperitoneal wall from diaphragma to linea cruciata and which is independent to various organs existing at retroperitoneal region.
In this report, the experience of a very large dermoidcyst which belongs to the benign tumor in retroperitoneal cavity is descibed with the references on it.
According to the recent statistical observation on 533 cases of retroperitoneal tumor in Europe and United State, the benign tumor is only 15-20% while a majority of them is malignant, and according to the observation in Memorial Cancer Center for 96 years, the ratio of the retroperitoneal tumor to the general tumor is 120: 6000.
Next, the retroperitoneal teratoma is relatively rare; for example, according to the Willis's report of 82 cases, the teratoma generated at the retroperitoneal region is only 3 cases (3.7%).
A case of dermoidcyst which is a relatively rare postperitoneal benign tumor has been summarily reported.
(1) The retroperitoneal tumor in a thirty-year-old woman.
(2) The secondary swelling of kidney due to pressure and the operative extraction of retroperitoneal dermoidcyst of about 6kg.
3) The references on the general postperitoneal tumors were statistically investigated.View full abstractDownload PDF (5726K) -
