JOURNAL FREE ACCESSThe vascular changes in renal cortex and medulla in 52 human kidneys of pyelonephritis were studied optical microscopically, electron microscopically, and microangiographically.
In addition, the intrarenal vascular changes in pyelonephritis were discussed in connection with hypertension. Cases were sub-divided into 3 according to their histological findings of pyelonephritis and into 2 based on their clinical blood pressure.
In acute or subacute pyelonephritis, there were little remarkable changes of renal artery in cortex and medulla and there was no finding of acute arteritis.
In chronic pyelonephritis, there were arteriosclerotic changes corresponding to the histological changes of interstitium.
In the severe cases of chronic pyelonephritis, the sclerotic changes in the cortex were stronger in arteria, and in arteriola than their ages, but particularly there was no acute severe changes such as fibrinoid necrosis.
Such findings will be explained by the slow deterioration of the vascular system in the cortex based on the interstitial fibrosis of pyelonephritis.
In the cases of hypertension, the vascular changes seemed to be stronger than those of normal blood pressure, but it was very difficult to point out the characteristic, morphological findings in the cases of hypertension. In pyelonephritis, there were very few cases of hypertension.
It seemed to be depended upon the far less findings of arteriolosclerosis in pyelonephritis than in glomerulonephritis or malignant nephrosclerosis.
According to the microangiographic findings of the severe cases of chronic pyelonephritis, the direct connections of afferent and efferent arterioles of glomerulus were revealed: the blood supply of the medulla, seemed better than expected.
Patho-histologically, the arteriolae rectae became narrow in such cases, and electron microscopically the atrophy of tunica media and the abnormal changes of basement membrance became revealed.
Such findings might be explained by the disturbance of blood supply in medulla in the severe cases off chronic pyelonephritis.View full abstractDownload PDF (9248K) -

JOURNAL FREE ACCESSAngiography and microangiography were carried out on 38 kidneys: 21 by operation, 17 in necropsy, and their findings were examined in connection with the histological findings.
After the irrigation by saline with heparin, barium sulfate was injected under the pressure of 150mmHg and radiogram was taken.
The sample for histological examination was taken from the kidney after angiography.
The findings of radiography were evaluated based on the abnormal findings such as stenosis, irregular lining, circular running, abnormal distribution and reduced branches in interlobar artery, arcuate artery, and interlobular artery.
1) In acute pyelonephritis, there were slight abnormal findings.
2) In chronic pyelonephritis, there were considerable differences among the cases.
3) In hydronephrosis, there were moderate changes in their vascular system.
4) In hydronephrosis complicated with chronic pyelonephritis, severe changes were revealed.
5) In most cases of renal tuberculosis, there were rather severe changes.
6) The special findings in microangiography such as stenosis, circular running, irregular lining of the arteries seemed to suggest the degree of the histological changes.View full abstractDownload PDF (3015K) -
Report 4. The Nervous Passways Controlling Seminal Emission and Closure of the Internal Urethral Orifice During Ejaculation (II)Yukio Kimura, Koyo Miyata, Kuniaki Adachi1972 Volume 63 Issue 5 Pages 343-345

JOURNAL FREE ACCESSThe peripheral nervous controls of seminal emission and closure of the internal urethral orifice during ejaculation were examined experimentally and the hypothesis reported in the previous paper was confirmed.
Methods: The hypogastric nerve and the fibers entering the hypogastric plexus which were grouped and referred to as the central branch of the hypogastric plexus and the lateral branch were exposed and sectioned. After 1-4 weeks postoperatively, the penis of the operated dogs was manually stimulated without anesthesia and changes in ejaculation were observed.
The results obtained are as follows:
i) Section of the bilateral hypogastric nerves. Ejaculation did not occur after 1-4 weeks postoperatively. Disappearance of ejaculation was found to be due to retrograde ejaculation, i. e. regurgitation of the semen into the bladder, but not due to the loss of seminal emission.
ii) Selective section of the nerve fibers entering the hypogastric plexus.
In the dogs whose median branch was cut, ejaculation occurred just like before section of the branch. No retrograde ejaculation occurred in these dogs. In 5 dogs whose lateral branch was sectioned, ejaculation disappeared in all dogs. In 3 of the 5 dogs retrograde ejaculation occurred and in a dog many spermatozoa were found in the urethra. In only one dog emission disappeared completely.
From these results it is concluded that the nerve fibers controlling seminal emission and closure of the internal urethral orifice during ejaculation may take different passways above the hypogastric plexus and these results also confirmed those reported in the previous report.View full abstractDownload PDF (443K) -
REPORT OF A CASE DEVELOPED ON THE PATIENT OF URINARY BLADDER TRANSITIONAL CELL CARDCINOMA AND DISCUSSION ON ITS ENTITYKimio Fujita, Koji Nakauchi, Keiichi Matsumoto, Terukazu Seta1972 Volume 63 Issue 5 Pages 346-352

JOURNAL FREE ACCESSK. T., a 27-year-old male had started with asymptomatic gross hamaturia in August 1964 and was diagnosed as the bladder tumor. Papillary tumors, mainly locating around the left ureteral orifice, were excised repeatedly through transurethral route. On July 6, 1965, the bladder was opened and 10 mCi/h of radon seeds were implanted in the bladder neck after the tumor resection. After repeated unsuccessful tumor resections, supplemented with the use of radon seeds, total cystectomy was performed on April 20, 1966. The distal lower half of the prostate including the seminal collide was not removed. Megalovoltage irradiation of 1, 980 R was administered.
As of March 20, 1970, 3 years-11 months after the total cystectomy, and 4 years-8 months after the radon seeds implantation, a rapidly developed large malignant mixed mesodermal tumor filled the pelvic cavity. The tumor was extirpated with the sigma and rectum. He died on July 24, with the local recurrent lesion and widespread metastases, showing no remarkable response to various antitumor agents.
On microscopic examination, repeatedly resected tumors of the bladder consistently revealed papillary transitional cell carcinoma. The tumor involving the pelvic cavity was composed of embryonal rhabdomyosarcoma, choriocarcinoma and squamoid cell carcinoma.
The relation between the concepts of rhabdomyosarcoma, botroid sarcoma and carcinosarcoma is reviewed. Though these terms are defined from various standpoints, some of them might be included in the cathegory of mixed mesodermal tumor.
The possibility of the intimate relationship between the radiotherapy and its oncogenic activity is also suggested.View full abstractDownload PDF (4592K) -

JOURNAL FREE ACCESSA case of priapism is reported and discussed.
1) The case is a 27 years old Japanese male, with idiopathic priapism associated with severe pain. Previously, he experienced transient episodes of priapism for two weeks. The duration of one of them was eight days.
Kymopsin 50 u per day was intramuscularly injected for 27 days, and no surgical treatment was done during admission. The effect was remarkable. Further, sexual intercourse after discharge was satisfactory with normal erection and sexual desire.
2) In the literature, some cases of medical treatment with α-kymotrypsin or fibrinolysin are reported, and Arfonad showed an excellently successful case in securing normal erection by this treatment. A great part of operative treatments such as aspiration for cavernosum of penis or sapheno-corporeal anastomosis were also good but sometimes accompanied by incomplete erection. The aspiratson method was more effective than the anastomosis.View full abstractDownload PDF (4400K)
