Colles' fracture is a common injury encountered in emergency departments. Despite the frequent experience of every orthopedic surgeon with Colles' fracture, considerable variation remains in the treatment of fracture of the distal radius. Everyone nearly agress that reduction of the fracture is not difficult, but maintenance of reduction is the problem. Eighty patients with Colles' fracture were treated with closed reduction and percutaneous pinning under the C-arm fields and followed up more than 1 year, from January 1990 to May 1993 at the Department of Orthopedic Surgery, Dae Han Hospital. The results of this study were as follows: 1. The fractures were classified according to the system of Gartland and Werley. Of the 80 cases, 12(5%) were type 1; 25(31%) type 2; and 43(54%) type 3. 2. Complications were such as; temporary neuropathy of median nerve 2 cases, redisplacement 2 cases, radiocarpal arthritis 1 cases, stiff hand 1 case and shoulder hand syndrome 1 case. 3. The overall assessment showed exellent in 29 patients(36.2%), good in 44 patients(55,0%) and poor in 7 patients(8.8%) under the subjective and objective criteria of Gartland and Werley and the objective criteia of Scheck. 4. The results were mainly correlated with maintenance of an anatomical reduction. 5. The percutaneous pinning was suitable for anatomical restoration and maintence, had less com plication and more advantage such as the early range of joint and simple technique. Conclusively, it was considered to be one of ideal method for the treatment of Colles' fracture in selected cases.

Three patients(1%) with recurrent molar pregnancy were managed arnong 317 registered molar pregnancies at the department of Obstetrics and Gynecology, Hanyang University Hospital between 197S and 1991. Reeurrent molar pregnancy seemed to be oaiated with a worsening histology and an increased incidence of proliferative trophoblastic sequelae in the successive episodes of hydatidiform mole. The treatment of recurrent mole is discussed and the literature regardmg recurrent rnolar pregnancy is reviewed.

Previous studies have shown that the cancer cell lines secrete multiple cytokines, such as macrophage colony-stimulating factor(M-CSF), granulocyte-macrophage colony stimulating factor(GM-CSF), interleukin-l(IL-1), interleukin-2(IL-2), interleukin-6(IL-6), and tumor necrosis factor-alpha(TNF-alpha). We evaluated the levels of IL-2, IL-6, and TNF-alpha in the ascites of 23 patients with ovarian cancer. These levels were then compared with cytokine concentration found in 10 patients who had benign ascites and also studied the relation between levels of cytokines and clinical parameters. Enzyme-linked immunosorbent assay(ELISA) was used to determine the levels of cytokines in ascitic fluids. The median age of the group was 56, and the median follow-up time was 24 months. The levels of IL-2 was not elevated in ascites of ovarian cancer(30.5 vs 37.2 pg/ml, p=0.083), 1 he levels of TNF-alpha in the ascites with ovarian cancer were higher when compared with ascites of benign disease and was nearly approached statistically significant(91.0+/-20.7 vs 440.2+/-117.9pg/ml, p=0.058). Significantly higher IL-6 levels were detected in patients ascites compared with ascites with benign disease(354.3+/-42.9 vs 5,605+/-1,137pg/ml, p=0.006). IL-6 and TNF-a levels in ascites did not correlate statistically with tumor volume, histologic type or with survival time. IL-6 levels did not correlated statistically with volume of ascites. IL-6 and TNF-a levels did not correlated either. Circulating platelet counts in patients with ovarian cancer were significantly higher than in patients with benign conditions (282.6+/-5 vs 388.4+/-21.2x-10(9)/l, p=0.003). Thrombocytosis(platelet counts>400x10(9)/l) occured in 35%(8/23) of the cases with ovarian cancer. IL-6 levels in ascites correlated signi-ficantly with circulating platelet counts(R=0.427, p=0.042). This study showed that the patients with ovarian cancer have elevated levels of IL-6 in ascites. IL-6 levels were not correlate with disease status in patients with ovarian cancer. However, the correlation was found between IL-6 levels and thrombocytosis. This observation suggest a role for IL-6 in the development of tumor-associated thrombocytosis. A larger study would help in evaluating the potential biological roles and use of cytokines as tumor markers in ovarian cancer.

The incidence of heterotopic gastric mucosa located in the submucosa in resected stomach specimens has been reported to be 3.0 to 20.1%. Heterotopic gastric mucosa is thought to be a benign disease, which rarely becomes malignant. Heterotopic gastric mucosa exists in the gastric submucosa, and gastric cancer rarely occurs in heterotopic gastric mucosa. Since tumors are located in the normal submucosa, they appear as submucosal tumors during endoscopy, and are diagnosed through endoscopic biopsies with some difficulty. For such reasons, heterotopic gastric mucosa is mistaken as gastric submucosal tumor. Recently, two cases of early gastric cancer arising from heterotopic gastric mucosa in the gastric submucosa were treated. Both cases were diagnosed as submucosal tumors based on upper gastrointestinal endoscopy, endoscopic ultrasound, and computed tomography findings, and in both cases, laparoscopic wedge resections were performed, the surgical findings of which also suggested submucosal tumors. However, pathologic assessment of the surgical specimens led to the diagnosis of well-differentiated intramucosal adenocarcinoma arising from heterotopic gastric mucosa in the gastric submucosa.

Cardiac myxoma is rare and has protean clinical manifestations mimicking various disease. Unless clinician has a high index of suspicion, the diagnosis can be easil missed. However diagnosis is all the more important since surgery can be dramatically successful, where as untreated myxoma invariably leads to death. Cardiac myxoma accounts for 50% of primary cardiac tumor and mainly originates in left atrium.(75%). The features of myxoma can be described under the three headings : Constitutional, obstructive, and embolic. From 1977 to 1985, the authors have experienced 30 cases of cardiac myxoma, one of which recurred. Of 29 patients, 8 were male and 21 were female. Their ages ranged from 11 to 55 years with average of 39.8 years. Constitutional manifestation was found in 25 of the 27 patients, obstructive manifestation in 27, and embolic phenomenon in 5. The diagnosis of myxoma was made on the basis of 2-D echocardiography. The sensitivity was 100%. Except 1 case who refused operation, all received surgical treatment. Immediate postoperative complication occurred in 6 patients(23%). Among them serious complication could be found only in 2 cases(7.7%). During long term follow up there was one recurrence and one patient with right ventricular myxoma has tricuspid regurgitation. In other cases, we could not found any problems.

In this study, gold nanotubes were fabricated by electrophoretic deposition using a titania nanotube layer as a template, and then the surface characteristics, biocompatibility and antibacterial effect of gold nanotubes were evaluated. Gold nanotubes of 100 nm diameter were fabricated by depositing 4 nm and 15 nm gold nanoparticles on anodized 100 nm titania nanotubes by citrate reduction and electrophoretic deposition. As a result of the UV-Vis diffuse spectrophotometer, 4 nm and 15 nm gold nanotubes showed strong absorption at 702~774 nm and 753~760 nm, respectively. Also, the maximum absorption wavelength was shifted to the longer wavelength as the coating time of the gold nanoparticles increased. FE-SEM observation and EDX analysis resulted that 0.1~0.5 wt% gold nanoparticles uniformly were stacked on the top layer of titania nanotubes. As a result of MTT cell test, the relative absorbance value of all experimental groups after 24 hours and 48 hours of incubation exceeded 70% indicating excellent biocompatibility. The effect of the near infrared laser light on the adhesion and growth of gold nanotubes showed excellent antibacterial activity regardless of the coating time of gold nanoparticles. Therefore, it is confirmed that the gold nanotube coating technology based on the titania nanotube template is supposed to be highly applicable to a titanium implant surface treatment technology with the remote control thermal treatment of a near-infrared laser.
