Open fracture characteristically has higher chances of infection and sof tissue damage in comparison with closed fracture. In spite of the development of operation methods and antibiotics, complications such as infection, nonunion, delayed union, and joint stiffness are continuously confronted as problems in the field of orthopedics. Different methods of treatment have been advocated as regards the care of the open wound and the method of stabilization of the fracture fragments. Therefore a comparative analysis of the type of open fracture and the bone union time according to the initial treatment methods was made from 47 cases over the age of 20, who were followed up until bone union developed among the inpatients who were treated for open fracture of tibia in the period of 7 years from January, 1982 to December, 1988, and the results are as follows: 1. The highest incidence of fractures was encountered in 3rd decade(34%) and male to female ratio was 6:l. 2. The most common cause of fractures was traffic accident(76.6%). 3. The most common level of fracture was in mid one-third and the bone union time was longest in mid one-third. 4. The bone union time was longer, and the rate of complication was greater in order of type 1, 2 & 3 according to Gustilo's classification. 5. The good result was obtained in type 1 fractures, by using the closed reduction & cast immobilization and pin & plaster method; in type 2, the bone union time was shortest in the cases of pin & plater method; in type 3, the bone union time was shortest in the cases of closed reduction or open, reduction & external fixation. 6. Bone union was obtained in all cases of delayed union and nonunion and the bone union time was shortest in cases treated with plate & bone graft.

This study was performed to observe the therapeutic effects of interferon-gamma(IFN-gamma) and gamma-globulin(gamma-globulin) in experimental Pneumocystis carinii pneumonia of immune suppressed mice. After 9 weeks, trimethoprim-sulfamethoxazole(TMP-SMZ; 10-50 mg/mouse/day), mouse IFN-gamma(5 x 10(4) units/mouse/day) and mouse gamma-globulin(20 mg/mouse/day) were administered to the mice for 3 weeks by the experimental group. The therapeutic efficacy was evaluated by body weights, histopathologic and electron microscopic findings of the lungs, and number of P. carinii cysts by Gomori's methenamine silver stain. Body weights of the mice were significantly increased in the group of combination therapy of TMP-SMZ with IFN-gamma or gamma-globulin, and in the group of TMP-SMZ treatment (p < 0.05), however, little effect was found in the group of gamma-globulin alone. Histopathologic findings of P. carinii pneumonia were much improved in the group of combination therapy of TMP-SMZ with IFN-gamma. Treatment with either TMP-SMZ or IFN-gamma significantly reduced the number of cysts in the P. carinii pneumonia, but gamma-globulin alone was ineffective. In electron microscopic findings of P. carinii pneumonia, the number of trophozoites and cysts were reduced by treatment with either TMP-SMZ or IFN-gamma, and most of the cysts were empty or containing one or two intracystic bodies. The present results suggested, that combination therapy of TMP-SMZ with IFN-gamma had synergistic effects in treatment of P. carinii pneumonia in experimental mice.

Bone grafts are used in the repair of segmental bone loss caused by severe trauma, bone tumors and infection, and to enhance bone healing in ununited fractures. Autograft is the most frequently used and the most effective method, but because of inadquate supply and additional operative morbidity, allograft or heterograft could be used. Heterograft has been shown to be poorly tolerated by the host and ineffective in providing an osteogenic system. The objective of this study is to observe healing process of a segmental defect of long bone following to heterograft, and to compare the difference of histologic process between autograft and hetero graft. Twenty-four white rabbits weighing 1,000 to 2,000 grams were used for the experiment. A segment measuring three times the diameter of the ulna shaft (1.5 to 2cm) of rabbit was resected with its periosteum. Twenty-four white rabbit were divided into three groups (control, autograft, heterograft group) according to graft methods, each group comprising of eight rabbits. The animals were sacrificed at 2, 4, 8 and 12 weeks after the experimental procedures and were periodically evaluated by radiographs and histology. The obtained results were as follows: 1. The results of the radiological evaluation showed that no ungrafted ulnar defects (control group) healed. In the heterograft group, partial union was observed from 8 weeks and complete union was obtained on 12 weeks. In the autograft group, partial union was observed on 2 weeks and complete union was obtained on 4 weeks. 2. The results from histological examination showed that the ungrafted ulnae did not heal across the defect but some immature trabeculae were founded on the edges of the defect. In the heterograft group, immature trabeculae were appeared from 4 weeks and defects were substituted with mature trabeculae on 12 weeks. In autograft group, defects were substituted with immature trabeculae on 2 weeks and with mature trabeculae on 4 weeks. As seen in the results of the experiment, union could be obtained with the heterograft, but needed more long time than autograft. Though the autograft is the most effective graft method in bone defect or non-union, above results suggest the heterograft as the alternative method in the treatment of large bone defect, in a multioperated patient, or in the children or the elderly, combined with autograft or alone.

Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.

Reactions from stinging insects are significant to dermatologists because of the wide variety of clinical presentations from mild local reaction to severe anaphylactic reaction. Although ant sting commonly occurs, it has been rarely reported in the literatures. We experienced a unique case with allergic reactions by the ant of the Cremawgaster iw6w urai vagala, subfamily Myrmicinae, family Formicidea, order Hymenoptera that has not been previously reported.

PURPOSE: To determine the plain film findings of acute neuropathic joint in diabetic foot. MATERIALS AND METHODS: Acute neuropathic joint in diabetic foot was considered when fragmentation of the articular ends of bone and subluxation of the affected joint developed within eight weeks after clinical onset of diabetic gangrene. Eight toes of six diabetics were satisfactory to our criteria. We analyzed plain radiographic findings of the affected joint and soft tissue, interval changes in follow-up radiographs, and deformities after healing. RESULTS: The time interval between clinical onset of gangrene and bone destruction ranged from 2 weeks to 4 weeks(mean 2.6 weeks). Plain radiographs showed fragmentation of the articular ends, subluxation, and soft tissue swelling of the metatarsophalangeal joint or interphalangeal joint. The significant feature of these patients was rapid progression of the lesions. Clinically, all patients had diabetic gangrene in affected toes, however, there was no evidence of osteomyelitis in our series. Amputation was done in 2 cases, and lesions in 3 of the remaining 4 cases were repaired spontaneously with regression of gangrene, leaving radiological residua such as pointed-end, tapered-end, and ball and socket deformity. CONCLUSION: Rapid disorganization of the joint with associated evidence of soft tissue gangrene in plain radiograph is believed to be valuable for the diagnosis of diabetic osteoarthropathy.
