BACKGROUND: Reactive oxygen free radicals have been implicated as an important factor in the development of ischemia-reperfusion injury of heart. Captopril, a SH-containing angiotensin converting enzyme(ACE) inhibitor has been reported to provide the protective effect in different models of myocardial ischemia and reperfusion injury of animal hearts. It is postulated that the myocardial protective effect may be related to a potential anti-free radical effect independent of ACE inhibition. The present study was designed to elucidate the myocardial protective mechanism of Captopril by investigating the drug effect on the experimentally induced oxygen free radical-mediated myocardial injury in isolated hearts of rats. METHODS: The heart isolated from rat was perfused retrogradly by Langendorff method. Myocardial dysfuntion was induced by oxygen free radicals generated by electrolysis of the perfusing solution(Kreb-Henseleit) with 2mA direct current for 45 sec. The cardiac functions(left ventricular pressure, dP/dt, heart rate, coronary flow) and the ventricular content of a lipid peroxidation product, malondialdehyde(MDA) were measured under presence of absence of Captopril and the compairing drugs(enalaprilat, cysteine and dithiothreitol). RESULTS: Electrolysis of oxygen-saturated Krebs-Henseleit perfusing solution led to the production of superoxide anion increasingly with intensity and duration of the applied electric current. The hearts perfused with the electroyzed solution demonstrated significant decrease in left ventricular pressure, dp/dt, heart rate, coronary folw and increase in myocardial MDA content. The depression of myocardial function as well as the increase of MDA content and oxygen radical production were reversed by Captopril(0.75~2mM) dose-dependently. Enalaprilat, a non-SH containing ACE inhibitor, however, showed no protective effect at all. Cysteine and dithiothreitol, the SH-containing agents without ACE inhibitory action showed also protective effects on the myocardial depression induced by electrolysis. CONCLUSION: It is suggested that Captopril may exert protective effect on oxygen radical-mediaed myocardial injury probably by its antioxidative and anti-free radical mechanism related to SH-group.

Serum lipids and lipoproteins were determined in 70 patients with hypertension, 40 patients with cerebral infarctions, and 41 patients with cerebral hemorrhage. The results were compared with findings in 64 healthy controls. The results are as follows; 1) Total cholesterol, VLDL-cholesterol, LDL cholesterol and total cholesterol/HDL-cholesterol ratio were significantly higher in patients with hypertension or cerebral infarction than in control group, but HDL-cholesterol showed no significant difference. 2) In Patients with cerebral hemorrhage, total cholesterol, LDL-cholesterol and HDL-cholesterol were higher than in normal controls. Total cholesterol/HDL-cholesterol ratio was within the limits of normal. It is possible that the susceptibility to cerebral infarction is the result of high total cholesterol/HDL cholesterol ratio rather than low HDL cholesterol. But our study suggests that hyperlipoproteinemia plays a minor role in the development of cerebral hemorrhage.

Most loci associated with type 2 diabetes mellitus (T2DM) discovered to date are within noncoding regions of unknown functional significance. By contrast, exonic regions have advantages for biological interpretation.

From Oct. 1974 to Jun. 1979, 47 diaphyseal fractures of the forearm bones in 36 patients were treated with compression plates. Among them 36 diaphyseal fractures in 28 patients (23 with acute fractures. and 5 with non-union) followed for average 8.3 months from three months to thirty seven months were studied. 19 fractures of the radius and 17 fractures of the ulna were treated with compression plates. Fifteen fractures which were delayed for operation for more than 3 weeks or had severe comminution, had primary iliac bone grafts. The fracture unlon of the radius and ulna was obtained in all cases and average healing time for the radius was 11.9 weeks and for the ulna was 12.3 weeks. The final functional results were excellent, 16 and satisfactory,7. The over all rates of excellent and satisfactory results were 82.2 percent. Therefore compression plate is one of the excellent methods to treat diaphyseal fractures and non-union of the forearm bone.

PURPOSE: More effective diagnosis and treatment through a survey on clinical aspect for the last 5 years and interrelation between cold agglutinin titer and mycoplasma antibody titer of Mycoplasma pneumoniae pneumonia. METHODS: 369 patients hospitalized in the department of pediatrics of Chung Goo Sung Shim Hospital for the 5 years from January 1990 to December 1994 have been surveyed, which diagnosed to be Mycoplasma pneumoniae pneumoniaby physical findings or chest x-ray findings with the titer of 1:64 in cold agglutinin test or the titer of 1:80 in Mycoplasma antibody test or forefold increase of any one or both of 2 titers in follow-up tes RESULTS: 1) More cases were found in 1990(76 cases, 20.6%) and 1994(181 cases, 49%) and the monthly distribution showed irregular fluctuations. Male to female ratio was 1:1.2 and high incidence was in the age of 3 to 5 years(27.9%), but 46 cases(12.5%) affected the infants below 1 year old. 2) Cough, fever, sputum were the most chief complaints. More moist rales, pharyngial injection, wheezing were found in physical examination. 86.7% of pneumonic infiltration were found in x-ray findings, 35.8% of which were both lung infiltration. The most common affected site was Rt. lower lobe and then Lt lower lobe and then followed by Rt. upper lobe. 71.8% of the whole cases were hospitalized for 5-8 days. 3) EM administration started 10-12 days after the onset in 29.3%. Mean duration of hospitalization of the cases administrated within 6 days from onset was 7.5+/-2 days, which was shorter than 8.4+/-3.5-that of the cases administrated after 6days from onset. The observation on those duration meant little atatistically(p>0.1) 4) The measure of Mycoplasma antibody titer in 142 cases among 245 positive cold agglutinin test case showed 61.3% of positive ratio. Positive ratio of cold agglutinin test peaked from 13th to 15th day after onset(89%) and went down(33%) after 19th day. Positive ratio of Mycoplasma antibody titer was at its summit(91%) from 7th to 9th day and went down(63%) after 16th day. decreased to 63% after 16 days. 264 cases tested simultaneously for cold agglutinin titer and Mycoplasma antibody titer. Titers of each simultaneous test for cold agglutinin and Mycoplasma antibody were in proportion each other(p<0.005, N=264, r=0.51). CONCLUSIONS: Mycoplasma pneumoniae pneumonia prevailed every 4 years(1990, 1994) and monthly distribution had been irregular. The most cases were found at age of 4 and 5. Mycoplasma antibody titer seems more effective for early diagnosis for Mycoplasma antibody titer showed high positive rate earlier and the rate went down earlier than cold agglutinin titer. The earlier diagnosis and treatment are required because of tendency of later erythromycin administration.

Granular cell tumors (GCTs) can be divided into neural type with S-100 reactivity and non-neural type without that. The latter has not been widely recognized and there are only fewer reports available when compared to conventional GCT. A 65-year-old man was presented with the presence of a painless mass on his back. The mass had developed into a small nodule on the scar developed because of previous surgery carried out 2 years ago. The tumor consisted of large, polygonal cells comprising of an enormous number of faintly eosinophilic small granules in the cytoplasm. The cytoplasmic granules were stained positively for periodic acid-Schiff stain. Immunohistochemical stains for S-100 protein and neuron-specific enolase were found to be negative. Herein, we report the appearance of a very rare case of non neural GCT developed on the surgical scar in support with relevant literature reviews.

Skin cancers usually occur on the face and so successive cutaneous reconstruction after surgery is very important for the patients' quality of life. Cutaneous reconstruction is especially difficult when the defects after surgery involve the nasolabial fold. The nasolabial folds run from each side of the nose to the corners of the mouth, separating the cheeks from the upper lip. This area has complex contours, unique skin color and texture and the limited availability of mobile adjacent skin. We reconstructed such a defect after Mohs micrographic surgery for basal cell carcinoma of the nasolabial fold area, and we used a subcutaneous island pedicle flap and periosteal suspension suture. Herein we report on the details with the pictures, and we discuss the cosmetic effect and limitations of this method.
