JOURNAL FREE ACCESSNeoplasm of the prostate, especially hypertrophic prostate were studied histochemically by determining the activities of aconitase (AC), succinic dehydrogenase (SD), malic dehydrogenase (MD) and lactic dehydrogenase (LD).
The activity, playing an important role in the metabolism of citric acid which tends to be accumulated in the hypertrophic prostate, was evaluated in the various types of diseased prostate.
1) Activities of AC, SD, and MD were observed in the glandular epitherial cells and were considered to be related to the cellular function and proliferation.
2) Active type of prostatic hypertrophy reveals a greater AC activity in the tissue compared with normal or inactive type of the prostate.
Inactive type shows a smaller activity than in normal tissue, and the activity is diminished in the epitherial glands at the site of glandular spase which is markedly enlarged.
3) AC activity in the stromal nodule is apparently greater than in normal or inactive type of prostate tissue.
4) A conclusion is drawn from the results that the significance of AC activity in relation to morphopathologic changes of prostatic hypertrophy is following.
Citrate in tts nature tends to accumulate in the prostate, and it begins to increase as the formation of stromal nodule progresses.
In early stage of prostatic hypertrophy, citrate is seemed to be metabolised by a sufficient increase in AC activity. As the hyperplasia of the glandular component setsin, citrate become increased in the glandular cells which is counteracted by AC activity increase while the cellular function is maintained.
When nodular hyperplasia progresses to the stage of detrimented glandular function, citrate metabolism and AC activity are broken up of their balance and invites impairment in TCA cycle metabolism end accumulation of citrate occurs.View full abstractDownload PDF (16022K) -

STATISTICAL OBSERVATION OF RETROPERITONEAL NEURILEMMOMAS AND RETROPERITONEAL TUMORS IN JAPANNorinobu Hayashi, Jitsukazu Tanimura, Hiroshi Furutama, Harunari Yamag ...1964 Volume 55 Issue 2 Pages 164-176

JOURNAL FREE ACCESSA case of a 60-year-old woman with primary retroperitoneal neurilemmoma was presented in detail. The statistical observation of retroperitoneal neurilemmomas and retroperitoneal tumors in Japan was made, and this case report is the 16th of the reports on retroperitoneal neurilemmomas.
Primary retroperitoneal neurilemmomas were seen in 16 (4.2%) of 378 cases of retroperitoneal tumor in Japan, which showed the highest frequency in the statistical observations previously reported.
The age ranged from 7 to 67 years old, and any significant difference were not seen by age. By sex the tumor occurred in male more than female at the rate of 2:1, by part on the left side more than the right at the rate of 6:1, and the majority of the tumors were as large as a child's head.
In Japan there has been no primary malignant retroperitoneal neurilemmoma like a case Melasson & Smith reported, but 2 (12.5%) of 16 cases relapsed after the surgical operation and died caused by multiple metastasis. In histopathological findings these cases did not indicate any malignancy, but from clinical point of view they were malignant.
From this fact it must be noted that the post-operative recidivum of this tumor occurs at considerably high frequency.View full abstractDownload PDF (5544K) -

JOURNAL FREE ACCESSPrimary neoplasma of renal pelvis are rare, by statistical report of many authors formed it about 5-10 per cent of all renal tumors.
In Japan 201 cases of tumors of renal pelvis were reported till 1960. The classification of these tumors discussed by many authors and today the benign papilloma, that were previously diagnosed, were considered as carcinoma first grade. We present here statistically the histopathological diagnosis of reported cases and short history of 2 cases of transitional celled carcinoma of renal pelvis.
The (pathological) diagnosis of 201 cases are as follows.
Benign papilloma 68 cases
Malignant papilloma 28 cases
Papillary carcinoma 30 cases
Squamous celled carcinoma 30 cases
Transitional celled carcinoma 15 cases
Basalcell-carcinoma 4 cases
Adenocarcinoma 3 cases
not papillary carcinoma 1 case
Carcinoma simplex 1 case
Cancer of renal pelvis 4 cases
Sarcoma 1 case
Tumor of renal pelvis 2 cases
not described 14 cases
Case 1: 44 years old man, visited our clinic 25th May 1960 with complaint of asymptomatic haematuria since 1 month. By cystoscopical and roentogenological examination are diagnosed as tumors of left kidney. Nephrectomized kidney showed papillary tumor at renal pelvis and small stone formation. Histological diagnosis: papillary transitional celled carcinoma.
Case 2: 66 years old woman suffered from slight abdominal pain of one week duration at light side. By another doctor found out swelling of right kidney and visited our clinic 10th May 1960. Pyelogram showed obstruction of right ureter and no image of right pelvis. Under the diagnosis of renal tumor nephrectomy performed.
Histopathological diagnosis: papillary transitional celled carcinoma of renal pelvis.View full abstractDownload PDF (5366K) -

JOURNAL FREE ACCESSA 8-year-old male child with complaint of hematuria was reported. Cystoscopy demonstrated a periodically dilating right ureteral orifice. Excretory urography associated with pneumoretroperitoneum revealed a so called “snake cap” at the terminal portion of right ureter. Ureterocelectomy was done and the postoperative course of the patient was uneventful.
Only 11 cases of ureterocele in infants and children have been reported in Japan. The reason why much more cases have not been reported is attributed to the fact that the pediatric urology has not yet well developed in Japan.
It was emphasized that cystoscopic examination should be conducted in any child with persistent pyuria.View full abstractDownload PDF (2855K)
