1.AVS(Audiovisual Stimulation)-Penogram.
Korean Journal of Urology 1988;29(3):459-469
In an effort to find more comprehensive and general diagnosis of erectile failure, we already have analysed 90 cases and reported the results. After that we added 199 more cases and performed a computer based analysis of total 289 cases in the dynamic changes of penile blood flow during natural physiologic erection after exposure to the audiovisual stimulation. The following results were obtained. 1. In normal volunteers, we were able to achieve uniform penogram findings in all cases with T.T.(Transit Time) ranging 1 to 3 minutes(mean 2.17 minutes), the EPT(Erection Persistent Time) over 30 minutes and no fluctuation phenomena after AVS. 2. Erectile failure group.(2.83 cases) (1) Group I.(108 cases; 38.2%). They demonstrated similar penogram features with the normal volunteers but EPT more than 5 minuets(mean 18.26 minutes) at least. most common causes were psychogenic origin(57 cases). (2) Group II.(175 cases ; 61.8%). Patients were showing abnormal penogram findings, and were divided into following 3 types. a) A type-Impossible type(10 cases ; 3.5%). They failed to show more than 2 fold increase in the maximal radioactivity after AVS when compared to the pre-stimuli level(mean 1.83 times). The underlying causes were identified to be arteriogenic and neurogenic. b) B type-Unstable type(124 cases ; 43.8%). They were unable to sustain erection due to fluctuation(mean 1.83 times). The underlying causes were psychogenic, vasculogenic and neurogenic origins. c) C type-Delayed type(41 cases ; 14.5%). They were showing T.T. more than 15 minutes(mean ; 23.71 minutes), and the underlying causes were arteriogenic, psychogenic and neurogenic origins. Based on these results, we have concluded that AVS-Penogram seems to the most appropriate diagnostic method for screening test and follow-up evaluation after vascular surgery. Through more clinical experience and investigation, and more comparison and analysis with other diagnostic methods, it will be a standard diagnostic approach in the future.

BACKGROUND: The oncogene, c-fos, is a useful marker of nociceptive neurons activated by various types of pain.However, the relationship between c-fos and acute pain induced by surgical incision has not been studied.The purpose of this study was to describe the expression of spinal c-fos in a rat model of postoperative pain. METHODS: Sprague-Dawley rats were used to enumerate spinal fos-like immunoreactive (fos-LI)-positive neurons after making sham, skin, or skin-muscle incisions on the plantar surface of the rat hindpaw. The spinal cords were divided into the following 4 segments for immunohistochemical detection of fos-LI at 3 time points after the incision (4 hours, POD1, and POD3):thoracic, upper lumbar, lower lumbar, and sacral.For analysis of the laminar distribution of fos-LI, the dorsal horn was divided into three regions (I-II, III-IV, and V-VI). RESULTS: The number of fos-LI was increased in the ipsilateral spinal dorsal horn in the lower lumbar segment 4 hours post-incision and was significantly greater in rats with skin-muscle incisions than in rats with skin-alone incisions.In the skin-muscle group, laminae I-II and V-VI had a greater number of fos-LI neurons than laminae III-IV.The increase in number of spinal fos-LI neurons normalized by POD1 and POD3. CONCLUSIONS: c-fos expression is confined to neurons of the spinal dorsal horn known to be activated by nociceptive stimulation. The larger the injury elicited, the greater the expression of c-fos, suggesting that the expression of c-fos can serve as a useful marker of activated nociceptive neurons caused by acute pain following surgical incision.Further study is required to elucidate why the degree of tissue injury affects the laminar distribution of c-fos expression.

3.A Study about Reliability of Radioisotope in Diagnosing Varicocele.
Korean Journal of Urology 1990;31(5):707-714
In order to consider the usefulness of radioisotope in diagnosing varicocele, a study was performed on 124 cases. Among them, 74 cases were diagnosed as varicocele, which included 16 cases of subclinical varicocele. Among 74 varicocele patients, 62 cases ( 83.8%) were diagnosed by varicocele index and 59 cases (79.7% ) were diagnosed by static image. A combination of the above two methods allowed 67 cases (90.5 %) to be diagnosed. 21 patients who had a high ligation of internal spermatic vein showed 11 excellent results, 6 good results and 4 poor results. Out of 10 patients with subclinical varicocele, there were 6 excellent results, 3 good results and 1 poor result and 9 patients showed improvement on postoperative semen analysis. There was no significant statistical difference in frequency of the testicular arterial insufficiency between the small varicocele group and the large varicocele group. Also, through scrotogram, it became known that semen analysis proved little help in aiding the diagnose of subclinical varicocele. In conclusion, 'Scrotogram proved very helpful in diagnosis and judging the results of operations of varicocele including subclinical varicocele.

Cystic teratoma on the floor of the mouth is infrequent disease and known as congenital origin. Teratoma has no sex distribution. Treatrnent of the cystic teratoma is completely surgical excision and recurrence is rare. The authors have experienced a case of cystic teratoma on the floor of the mouth in neonate. We reported this case with review of literatures.

Multilocular cystic renal cell carcinoma appears to be a distinct and rare subtype of renal cell carcinoma with characteristic gross and microscopic features. Multilocular cystic renal cell carcinoma should be separated from multilocular cyst, multilocular cystic nephroma, and renal cell carcinoma with cystic degeneration. We present a case of multilocular cystic renal cell carcinoma. A 61-year-old man presented with right flank pain for 4 years. The computerized tomography revealed multilocular cystic mass in the upper pole of right kidney. The cystic mass measured 4.5x4 cm. The cyst was multilocular and locules not communicated with each other. The solid area was not present. Microscopically, the locules were lined by flat or cuboidal neoplastic clear cells. The clear cells were focally aggregated in the septa. The nephron was not present in the septa.

It is important to predict the prognosis of patient with cancer. Well known parameters predicting the prognosis are staged and degree of differentiation. Recently, the prognostic and diagnostic significance of silver-stained nucleolar organizer regions(Ag-NORs) and flow cytometric DNA analysis are introduced. This study aims to detect the diagnostic significance of Ag-NORs in breast lesions, and to correlate the number of Ag-NORs and cellular ploidies in breast carcinoma. In addition, the existence of heterogeneity according to the sample in the same patient is studied Sixty six paraffin blocks(two primary lesions and the two metastatic lymph nodes in 13 patients, and one primary lesion and one metastatic lymph node I 10 patients) of breast carcinoma, 30 paraffin blocks of fibroadenoma and 23 paraffin blocks of normal breast are studied. The numbe of Ag-NORs increase from normal breast(mean 1.45) through fibroadenoma(mean 1.60) to carcinoma(mean 2.43). It was significantly different between each lsions(P<0.0005). The number of Ag-NORs increased in the aneuploidy carcinoma than that in the euploidy one(P<0.05). But, there was difference between the number of Ag-NORs and DNA index according to the sample area in the same patient with carcinoma. In conclusion, the number of Ag-NORs is diagnostically significant in breast lesions and is correlated with cellular ploidies in breast carcinoma. In addition, Ag-NORs and cellular ploidies are heterogenous in the same patient.

Extravasation of toxic chemotherapeutic 'agents cause severe skin ulceration and necrosis which often need secondary surgical intervention. Still, there were not established antidote agent in case of extravasation with mitomycin-c. Dimethyl sulfoxide is known as an effective chemical scavenger of toxic hydroxyl free radical and sodium thiosulfate also was demonstrated significant protector from mitomycin-c induced ulceration by a few experimental studies. Author investigated necrotic area of mitomycin-c injected site and compare to the effectiveness of topical treatment with dimethyl sulfoxide and intradermal injection of sodium thiosulfate according to starting times, forty five mice were divided into 3 groups. Control group(n=5) had no treatment after subcutaneous injection of mitomycin-c. Experimental group I and 11 were 20 mice treated dimethyl sulfoxide and sodium.
