From January 1985, to June 1986, 7 cases in which supracondylar and intercondylar fractures of the femur were treated at our orthopaedic department using the Extensile Approach for an anatomical reduction and firm internal fixstion, show successful results in follow up stuides. l. All 7 cases were type III fractures of Neers classification. 2. Among the 7 cases treated surgically using the Extensile Approach, 5 cases showed excellent and good results and the remaining 2 csses showed one fair and one failed results. 3. Probably due to the additional open proximal tibia and patella fracture and delayed surgery from trauma one case had a fair results. The case which failed wss due to ipsilsteral ligamentous injuries and a nerve injury in addition to the femur fracture and slso the impossibility of early knee joint exercise due to associated injuries. 4. None of the results of the 7 csses had any relationship with the patients age. 5. One case of postoperative skin necrosis developed around the tibial tuberosity and was treated successfully by a cross leg flap. 6. In comminuted supracondylar and intercondylar fractures of the femur, the Extensile Approach is thought to be an excellent surgical technique by means of a wide surgical field for an anatomical reduction and firm internal fixation with the repair of associated ligamentous injuries.

Congenital pseudarthrosis of the tibia was accepted as one of the most difficult disease in respect of the frequency and treatment for the orthopaedists. Since April, 1984, we experienced 3 cases of congenital pseudarthrosis of the tibia, one 2 year-old boy involved left tibia only and the other 4 year-old female involved bilaterally, obtained solid bony union in all which were treated by massive surgical management that contained vascularized bone graft and electric stimulation. Several complications were faced such as refracture, valgus deformities of the ankle, skin irritation sign, angular deformities. But refracture was healed without delayed or nonunion by simple plaster cast immobilization. The vascularized bone graft snd electric stimulation is thought to be more improved methods for the treatment of congenital pseudarthrosis of the tibia. Althought solid bony union was obtained in congenital pseudarthrosis of the tibia, periodic follow-up and adequste management must be mandatory up to the end of the bony growth.

Benign tumors and tumor like lesions in the foot are uncommon and those that are malignant are rare. Metastatic cancer of bone distal to the knee and elbow is unusual. By contrast, non-tumorous lisions that cause swelling, pretuberance, or deformity are common. Fifty two cases of tumors on foot were treated at our department from Jan. 1970 to Dec. 1991, we have treated fifty two cases of foot tumor and analysed their clinical characteristics. Bone tumors were more frequent than soft tissue tumors (2:1). Among soft tissue tumors benign tumors were frequent than malignant(1.4:1), and fibroma was the most frequent tumor(30%). Benign soft tissue tumors occured frequently at Edward and Michael's Zone 3(57%). Benign bone tumors has higher incidence than malignant(20:1). Osteochondroma was the most frequent tumor (48%). Predilection sites for osteochondroma and enchondroma of foot was distal phalanges and mitatarsal bone, respectively.

We intended to evaluate the Young's modulus of trabecular bone and apparent density from Computed Tomography(CT) and Spherical Indentation test and to quantify relation ship between them. The distal femurs(31 age, male, left and right) were prepared for exprimentatin and were embedded with repect to anatomical orientation. Then the specimens were scnned at 1 mm intervals on GE9800 CT scanner and the Hounsfield Units(HU, or CT number) were extracted from each CT image. After scanning, the bones were sectioned with diamond saw, producing 8 mm cubes of trabecular bone(72 eachs) from the metaphyseal region of both distal femur. The cubes were mechanically tested in inferior-superior(IS), anteriorposterior(AP), and medial-lateral(ML) direction with custom-made device, Spherical Indentatin Tester. After testing, the real apparent density of specimens were measured. The results of this study showed that the IS modulus was singificantly greater than both the AP and ML modulus and the AP modulus was also greater than ML modulus significantly(p<0.01). A linear relation ship between HU and real apparent density was found to be significant(R2=0.68) and significant power relationship between the apparent density and the tangent moduli(either by CT or physical measures) was also found.

OBJECTIVE: Our purpose was to investigate the relationship between the levels of IL-6 and tumor necrosis factor-alpha in the peritoneal fluid(PF) of women with and without endometriosis and infertile women. Design: Prospective and case-control study. Setting: University hospital. Patients: Twenty-nine women with laparotomy or laparoscopic findings of minimal to severe endometriosis, and twenty-eight women with no visual evidence of pelvic endometriosis and with benign gynecologic disease. Main Outcome Measures: PF IL-6 and tumor necrosis factor-alpha levels were determined using commercial ELISA. IL-6 and tumor necrosis factor-alpha concentrations were compared among women with and without endometriosis, and with infertile and fertile women, and then also compared according the revised American Fertility Society classification. RESULTS: IL-6 and tumor necrosis factor-alpha concentrations were higher than in the PF of women with endometriosis than in matched normal controls. Cyclic variations in IL-6 concentrations were seen in PF from patients with endometriosis: the concentrations in the secretory phase were significantly higher than those in the proliferative phase. IL-6 concentrations were higher than in the PF among of infertile women than in fertile women. A significant correlation between PF IL-6 and tumor necrosis factor-alpha concentrations and endometriosis stage III and IV was noted. CONCLUSIONS: Increased PF levels of IL-6 and tumor necrosis factor-alpha in patients with endometriosis may be relate to endometriosis-associated infertility and to the pathogenesis of endometriosis suggesting that partially contribute to the disturbed immune regulation observed in patients with endometriosis.

Hypothalamic suprachiasmatic nucleus (SCN) is a circadian pacemaker which controls diurnal behavioral and hormonal rhythms in mammals. The SCN receives environmental light signals through the retinohypothalamic tract, and glutamate is the major excitatory neurotransmitter in the retinohypothalamic tract. In the present study, we investigated the developmental expression of the mRNAs for N-methyl-D-aspartate type glutamate receptor (NR)1, NR2A, NR2B and NR2C subunits in the rat SCN using in situ hybridization with specific riboprobes. At postnatal day 2 (P2), P8, Pl5 and P45, the high level of NRI transcripts was observed in both ventrolateral and dorsomedial subdivisions of the SCN, and the distinct expression of NR2C mRNA was principally found in the dorsomedial SCN. The weak NR2B mRNA expression was clearly found in both subdivisions of the SCN at P2 and P8, whereas specific NR2B hybridization signals were not found at Pl5 and P45. There was no specific hybridization signal of NR2A in the SCN throughout the postnatal life. These findings implicate that NR may play an important role in the neonatal SCN. In addition, this study suggests that NR1, NR2B and NR2C might be the major NR subunits in the developing SCN, whereas NRI and NR2C could be the subunit components of NR in the adult SCN.
