The index on myocardial contractility of pure mitral regurgitation(MR) after mitral valve replacement is believed to be useful in determining proper operation time before irreversible myocardial damage by volume overload. Thus the authors examined pre and post-operative echocardiographic results of 20 cases of pure MR patients who had been admitted to Pusan National University hospital and compared the usefulness of each index. Pre and post-operative echocardiographic results were as follows respectively ; 1) Left ventricular internal dimension in diastole(LVIDd) were 6.49+/-0.19cm and 5.51+/-0.17cm. 2) Left ventricular internal dimension in systole(LVIDs) were 4.26+/-0.12 and 3.79+/-0.18cm. 3) Ejection fraction were 71.28+/-1.57% and 59.24+/-3.05%. 4) Fractional shortening(FS) were 34.09+/-1.18% and 27.21+/-1.84%. 5) Mean Vcf were 1.53+/-0.08cm/sec and 1.18+/-0.09cm/sec. 6) Left ventricular end-diastolic volume index(EDVI) were 196.35+/-18.33cc/m2 and 98.46+/-9.96cc/m2. 7) Left ventricular end-systolic volume index(ESVI) were 55.28+/-5.12cc/m2 and 41.88+/-6.07cc/m2. 8) Left ventricular end-systolic wall stress/ESVI(ESS/ESVI) were 2.3+/-0.21 and 3.91+/-0.83. ESS/ESVI showed significantly(p<0.05) elevated postoperative change, LVIDd, LVIDs, EF, FS, EDVI, ESVI revealed significantly(p<0.05) reduced postoperative change whereas Mean Vcf had no postoperative change. After examining correlation between preoperative and postoperative results of each index, it is believed that LVIDd, LVIDs, and ESS/ESVI were useful prognostic indices but were unrelated to postoperative ejection phase indices such as EF, FS, and MEan Vcf. Especially in case of LVIDd>6cm, LVIDs>4cm, and ESS/ESVI<2, the prognosis was poor due to myocardial damage by mitral regurgitation.

Roux-en-Y ileosigmoidostomy with or without rectosigmoid pouch was done to know how these prevent the reflux of intestinal contents into the urinary tract. Twenty one New Zealand white rabbits were divided into three groups, Group t of Roux-en-Y ileosigmoidostomy, Group II of Roux-en -Y ileosigmoidostomy and end to side rectosigmoidostomy 5cm distal to the ileosigmoidostomy site, and Group III, same as Group II with the distance of 10cm. Direction of stream of bowel contents. frequency of peristalsis and pressure of bowel segments were observed with fluoroscopy and urodynamic evaluation. When the contrast media were infused through proximal sigmoid, reflux of contrast media from colon to ileum was occurred least frequently (14.3 %) in Group III. When the contrast media were infused through the ileal segment of Roux-en-Y, reflux of contrast media from ileum to the proximal sigmoid colon was occurred least frequently (28.6 %) in Group III. These observations show double Roux-en-Y ileosigmoidostomy with rectosigmoidostomy is one of effective mechanism to prevent reflux of fecal stream from urinary tract. The optimal distance between ileosigmoidostomy and rectosigmoidostomy sites will be a major factor to exert the maximum antireflux effect.

The ulcerative colitis is a relatively common disease in the European and North American countries aince Dr. Wilks has first reported the cases in 1895, But in Korea, this disease is a rare entity and only a few case have been reported. However, rescently the diagnoetic methods for ulcerative colitis are much developed we have experienced 28 cases of ulcerative colitis which were diagnosed by endoscopy, barium enema exam and biopsy. Therefore a total of 28 patient with ulcerative colitis diagnosed and treated at the department of internal medicine of HYUH from June 1979 to June 1986 was reviewed. We obtained the results as follows; 1) The sex distribution assumed a ratio of 1 to 1.33 with 12 males and 16 females. 2) The age dietribution was relatively even but the majority of cases were between 5th and 6th decade (32.1%), 3) The most prominent clinical symptoms were rectal bleeding, abdominal pain, diarrhea, fever, wight loss and vomiting. 4) Significant laboratory findins were anemia, eleveited ESR, leukocytosis, positive stool OB, electrolyte imbalance and decreased serum albumin level. 5) As to the extent of disease determined by the barium enema examination and endoscopic exam., rectum or rectosigmoid colon is involved in majority of the cases (92.8%). 6) The endoscopic examination was performed in all 28 cases and showed significant findings such as ulceration, hyperemia, mucosal friability, bleeding etcs. 7) The barium enema examination was performed in 19 cases and showed positive findings such as ulceration, luminal narrowing, bowel shortening and rigidity in 17 cases. 8) 21 of 28 patients treated by medical therapy showed relatively improved but 4 of 28 patients was exacerbated or relapsed and one has expired.

We report herein three cases of subcutaneous sarcoidosis without apparent internal lesion. The patients had multiple subcutaneous nodules on the extremities and abdomen. Hyper-gammaglobulinemia, a relative increase of T suppressor cells, and increased serum angiotensin converting enzyme level and skin anergy were observed. Histopathologic findings revealed sarcoidal granulomas involving the subcutaneous fat tissue. The lesions of two cases resolved spontaneously and the other one case required systemic corticosteroid therapy.

Although vitiligo is a common disorder with well-known clinical features, its etiology is still vague. It has been suggested that immunologic factors are important in the pathophysiology of vitiligo. And the association of HLA antigens with vitiligo has been reported. Authors examined HLA phenotypes in thirty-nine patients, T lymphocytes in thirty- three patients, B lymphocytes in thirty-one patients, and quantitation of IgG, IgA, IgM and IEP(immunoelectrophoresis) in twenty-five patients with vitiligo in this study. T3 and T4 were investigated in twelve patients, CBC in thirty-nine and urinalysis in thirty-five patients with vitiligo for screening of associated diseases ; thyroid disease, anemia and diabetes mellitus. The results are as follows; The frequency of HLA A9, Bw15 and Bw22 was significantly decreased in vitiligo patients compared to control group(p=0. 003, 0. 02, 0. OR) 2. There were no significant differences in the results of total and active lymphocytes and B lymphocytes in vitiligo patients compared to the control group. The results of quantitation of IgG, IgA, IgM and IEP showed within normal lirnits except one, an increased IgG, 2,200rng/100ml (normal: 500 1,500) and polyclonal gammopathy. 4. Among twelve vitiligo patients, one showed increased TR, 355ng/100ml (normal: 80 220) and T4, 17. 3pg/100ml (normal: 5 13). 5. CBC and urinalysis were within normal limits in all patients.

BACKGROUND: It is reported by rnany t,hat UVB and large coses of UVA damage epidermal Langerhans cells. UVA irradiated skin produces reactive oxygen soecies such as superoxide anion(O ), hydrogen peroxide(H O), hydroxyl radical( OH) and singlet oxigen(O ). Reactive oxygen species such as O are invnlved in the process of decreasing the number if epidermal Langerhans cells after irradiation with UVB. However, no well established studies have been carried out after irradiation with UVA. OBJECTIVES: We wished to find out whether the UVA-induced decrease in the number of Ia Langerhans cells would be protected by scavengers of reactive oxiygen species. METHODS: We irradiated 200J/cm and 400J/cm of UVA on thi ears of C3H mice with or without intravenous injectior. of SOD, catalase, and sodium azide which are the scavengers of O , HO and O, respectively. We biopsied the ears of mice 2 days after irradiaion, stained them with immunope-roxidase technique, and counted the number of Langerhans cells. RESULTS: 1, There was significant decrease in the number of Ia Langerhans cells in the 200J/cm or 400J/cm of UVA irradiated group compared to the normal control group. 2. The pretreatment groups with SOD, catalase, and sodium to before irradiation with 200J/cm or 400J/cm of UVA showed less decrease in the number of la Langerhans cells compared to the 200J/cm or 400J/cm irradiated group with UVA only. CONCLUSION: Frorn the above result, we can deduce that reactive oxygen species are involved in the decrease in the number of Ia Langerhans cells induced by 200J/cm. or 400J/cm of UVA irradiation.
