This study was undertaken to observe the mutagenic occurrence in urine excreted after the ingestion of roast beef. Two healthy nonsmoker persons of both sex were selected for this test, employing two strains (TA98, TA100) of Salmonella typhimurium according to Ames' method. The mutagenic activity began to appear in urine of both sex three hours after ingestion of 300 g of roast beef, gradually increasing until 6 hours and declining thereafter.

OBJECTIVES: To test the hypothesis that the endometrial stromal cells from patients with endometriosis responds differently to the insulin-like growth factor (IGF) compared with those from patients without endometriosis. METHODS: IGFs in peritoneal fluid (PF) from patients with endometriosis(n=18) and without endometriosis(n=12;control patients) were measured by radioimmunoassay. Endometrial stromal cells from patients with endometriosis and control patients were cultured in serum free media(SFM) in the presence or absence of PF or IGF-I(0.25-25 ng/ml) or IGF-II(5-50 ng/ml) and the proliferation of endometrial stromal cells were evaluated by [3H] thymidine incorporation test. All statistics were performed by ANOVA test and student's t-test. RESULTS: When added to SFM, IGF-I(1-25 ng/ml) increased thymidine incorporation in both endometrial stromal cells from patients with endometriosis and control patients in dose dependent manner and IGF-II(5-25 ng/ml) gave similar response in latter cells but not in former cells. Within low IGF-I(less than 100 ng/ml) PF group or high IGF-I(more than 100ng/ml) PF group, the type of endometrial stromal cells did not result in any difference in thymidine incorporation. However, regardless of the source of stromal cells, high IGF-I PF group produced a greater extent of thymidine incorporation than low IGF-I PF group in patients with endometriosis but not in control patients. Also, thymidine incorporation was higher in high IGF-I PF group of former patients than in the same group of latter patients. PF induced higher thymidine incorporation in endometrial stromal cells than the same levels(0.25-2.5 ng/ml) of IGF-I directly added to SFM. CONCLUSIONS: The effects of IGF-I in PF on endometrial stromal cells are similar regardless of their source and IGF-I is one of several growth factors that may participate in the growth of endometrial stromal cells in pelvic endometriosis.

PURPOSE: This study was performed to evaluate the efficiency of Platelet-rich plasma (PRP) for acceleration of bone healing process on allograft transplantation after curettage in benign bone tumor. MATERIALS AND METHODS: From December 2007 to February 2009, twenty-one patients who had benign bone tumor and underwent allograft transplantation after curettage were evaluated. Mean follow-up period was 14.6 months (range, 12-26 months). We compared with 13 cases of PRP group and 8 cases of non-PRP group in terms of size of lesion, bone resorption, amount of applied PRP and complications. The mean age at surgery was 23.6 years (range, 4-73 years). The most common diagnosis was simple bone cyst (7) followed by enchondroma (4), giant cell tumor (3), undifferentiated benign bone tumor (3) and so on. RESULTS: The mean size of lesion was 33.5 cm3 (range, 2.3-181.9 cm3) (29.4 cm3 in PRP group and 40.2 cm3 in non-PRP group). The mean volume of injected PRP was 7.4 cc (range, 3-12 cc). Bone union started at 3.0 months (range, 1.5-5.8 months) in PRP group and 5.3 months (range, 4-8 months) in non-PRP group. Three cases for each group were excluded due to recurrence and pathologic fracture. One patient had febrile episode 3 weeks later after surgery which subsided with antibiotics. CONCLUSION: The PRP could accelerate bone union in allograft transplantation after curettage of benign bone tumor. Furthermore, we expect that PRP can accelerate bone union in fracture or non-union.

We have had the opportunity to investigate a case with traumatic middle cerebral artery occlusion. The patient was 47 years old male who developed right hemiplegia and aphasia after collision with a automobile vehicle. Cerebral arteriography demonstrated complete occlusion of the left Sylvian middle cerebral artery distal to the origin of the operculofrontal arteires. The computed tomographic scan of the brain revealed dense infarction on the left temporoparietoccipital lobe. With repeated studies on 6 weeks and 6 months after trauma, confirmed partial clearing of the previously occluded middle cerebral artery in cerebral arteriographies and on interval change in computed tomographic scans. Comparable reported cases and theories of pathogenesis are discussed.

5.An Explanatory Model for Health-Promoting Behaviors in Patients Living at Home who have Post Stroke Hemiplegia.
Journal of Korean Academy of Nursing 2006;36(6):1065-1075
PURPOSE: A structural equation model was analyzed to explore the determinants of health-promoting behaviors in patients living at home in Korea who had post stroke hemiplegia. METHOD: Demographic characteristics, activities of daily living, religiosity, family support, self-efficacy, acceptance of disability, perceived barriers to health-promoting activities, depression, and health-promoting behavioral data was collected from 239 patients using self-report questionnaires. RESULT: Variables that have a direct effect on health-promoting behaviors were self-efficacy and family support. Depression, acceptance of disability, perceived barriers, activities of daily living and religiosity also influenced health-promoting behaviors in an indirect way. CONCLUSION: It is imperative to explore strategies for patients with post stroke hemiplegia to identify and maximize their resources, develop their self-efficacy, improve their emotional state, and enhance their physical activity and spiritual growth, which would maximize health-promoting behaviors.

OBJECTIVE: The objective of this study was to compare results of the macroscopic one-layer vasovasostomy with those of microscopic one-layer vasovasostomy and to analyze the change of semen parameters according to the interval of vasal obstruction. METHOD AND MATERIALS: Between March 1987 and December 1997, we performed 121 vasovasostomies using modified one-layer technique with loupe magnification (macroscopic vasovasostomy) or microscope. Among the 68 could be followed post-operatively, 37 patients were treated by macroscopic technique with loupe, and 31 patients by microscopic technique. We compared rates of anatomical patency (sperm count above than 10x106/ml) and pregnancy of macroscopic vasovasotomy with those of microscopic vasovasostomy. Patency and pregnancy fates according to vasal obstructive interval were also examined. RESULTS: The patency rates of macroscopic and microscopic technique were 86.5% and 87.1%, and pregnancy rates of macroscopic and microscopic technique were 64.9% and 67.7%. There was no statistical significance between these two methods (p>0.05). The pregnancy rates and sperm motility were decreased if more than 10 years had elapsed following vasectomy(p<0.05). CONCLUSION: We found little difference in success rates resulting from macroscopic and microscopic vasovasostomy and the former had the advantage of reduced cost and a lower operator skill level. in post-operative semen analysis, the sperm motility was the most probable factor associated with vasal obstructive interval.

7.Clinical Aspect of Central Serous Retinopathy.
Journal of the Korean Ophthalmological Society 1978;19(2):165-173
The author surveyed on the ration of central serous retinopathy (C.S.R.) cases among total out patient, distribution of sex, distribution of age, sites of affected eye, and visual acuity in 271 cases of central serous retinopathy from March, 1973 to April, 1977. Fluorescein angiography was performed in 71 cases among them. Leakages of fluorescein were analysed by pictures. The results are obtained as follows: 1. The eyes of C.S.R. were observed in 0.75% among total out patients. 2. As to the distribution of sex, male were observed in 71.4%. 3. Among 271 cases, Unilateral affected cases (83.4%), and there were no difference between right and left eyes. 4. As to the distribution of age, 4-th decade were most frequently affected in 35.4%. 5. The cases were classified by leaking pattern as followings; Type I: Leaking was unremarkable. Type II: Leaking point appeared at early arterial phase and fades out gradually. Type III: Learking point appeared at early arterial phase and increased in density gradually, but the size of leaking area wes not enlarged. Type IVa: Leaking point appeared at early arterial phase and increase concentrically in the density and size. Type IVb: Leaking point appeared at early arterial phase and increased vertically (mushroom-shaped) in its size and density. 6. Type IVa in leaking pattern was most frequently observed. 7. A single leakage was found in 39.5% of all cases. 8. The leakages of fluorescein were found most frequently in the upper area particullary in the upper nasal area of the macula.

8.Effect of Tension-Free Vaginal Tape Procedure in Women with Recurrent Stress Urinary Incontinence.
Korean Journal of Urology 2005;46(10):1071-1077
PURPOSE: To evaluate the efficacy of the tension-free vaginal tape (TVT) procedure in patients with recurrent stress urinary incontinence. Therefore, the effectiveness of the procedure in patients whom previous traditional surgical procedures had failed was retrospectively reviewed. MATERIALS AND METHODS: A total of 48 women, in whom a previous traditional surgical procedure had failed, received the TVT procedure (Group I). A further 124 women received the TVT procedure as the primary anti-incontinence surgical procedure (Group II) over the same time period, who were followed up for at least 1 year after the TVT procedure, were also included in the study. The preoperative evaluations included a symptom questionnaire, physical examination and urodynamic evaluation. Uroflowmetry, postvoiding residual urine and the symptom questionnaire were evaluated postoperatively, and the pre- and postoperative results compared between the two groups. The surgical results were classified into 3 categories; cured, improved and failed. RESULTS: According to the protocol, 40 (83.3%) and 106 (85.5%) patients in Groups I and II were cured. There were no significant differences in the cure rates between the two groups. Thirty four and 58 intrinsic sphincter deficiency patients were noted in Groups I and II, respectively; of these, 76.5 and 79.3% of the patients in groups I and II were cured of their incontinence. There were no significant differences in the incidences of intra- or postoperative complications, postoperative voiding problems and patient satisfactions between the two groups. CONCLUSIONS: There were no differences in the results of the TVT procedure in women with recurrent stress urinary incontinence or who had received the procedure as the primary anti-incontinence surgical treatment. These results imply the TVT procedure can be performed as the primary choice in patients having failed previous anti-incontinence surgery.

We compared the left ventricular ejection fraction by echocardiography with the ejection fraction determined by computerized radionuclide ventriculography in 59 patients who were admitted to the Soon Chun Hyang University Hospotal under the impression of cardiovascular disease from May 1984 to August 1985. The results were as follow : 1) In all patients the ejection fractions by both methods were significantly correlated with each other(r=0.77, P<0.001). 2) In 10 patients with ischemic heart disease the ejection fractions by both methods were not correlated significantly(r=0.42, P>0.10). 3) Except the 10 patients with ischemic heart disease, the ejection fractions by both methods were correlated significantly(r=0.87, P<0.001). 4) In conclusion, though the ejection fraction by the above 2 methods represent the left ventricular function well, the ejection fraction by echocardiography can not represent the left ventricular function precisely in patients in patients with ischemic heart disease because of abnormal left ventricular wall motion and left ventricular function more precisely than that by echocardiography.
