Fractures of the tibia are frequently encountered in mordern civilized society. Especially, those in distal 1/3 of the tibia have so many problems, such as angular deformity, osteomyelitis and nonunion because of anatomically scanty soft tissue. Many modalities of the treatment of fracture of distal 1/3 of the tibia were introduced. Among them, interlocking IM nailings were considered as one of the best modality. But, in interlocking IM nail, reaming of the medullary canal which destroys the endosteal circulation and causes thermal necrosis of the inner aspect of the cortical bone results in delayed union. And also, procedure for distal screw fixation is difficult and time-consuming. As for using flexible IM nails for fractures of distal 1/3 of the tibia, it was considered as not so satisfactory method due to lack of stability of fixation. However, the stability of fixation can be strengthened with fanning of the nails in distal fragment, using more than 3 nails and delay the protected weight bearing. Authors studied 25 cases of fractures of distal 1/3 of the tibia treated with closed flexible IM nailing at Sung Ae General Hospital, from July., 1987 to July., 1989, and obtained following results: 1. Among 25 cases, 4th decades were most common and males were more commonly involved. 2. Traffic accidents were the most common causes of injury and majority of 16 open fractures and 19 comminuted fractures, were caused by high energy mechanism. Among open fractures, type II were most common. 3. Two angular deformities less than 10 degrees, one proximal migration and one checkrein deformity were observed as complications, but, no clinically significant complications were noted. 4. The time for radiological union were 14.5 weeks in group without fibular fracture and 15.1 weeks in group with fibular fracture, and 14.0 weeks in closed fracture group and 17.2 weeks in open fracture group, and average in 15.6 weeks.

BACKGROUND/AIM: The lipo-PGE1, known for being more stable during pulmonary circulation and having more targeting effect, has been reported to inhibit ET-1 induced stellate cell contraction. We assessed the effect of lipo-PGE1 on the change of ET-1 concentration and the relationship between ET-1 concentration and the liver damage. METHODS: Mongrel dogs weighing about 25 kg were divided into a control (n=6) and a lipo-PGE1 (n=6) group. Partial liver allotransplantation was performed. In the lipo-PGE1 group, lipo-PGE1 was slowly infused through splenic venous cannulation during the donor liver harvesting procedure (50 microgram) and continuously infused (60 microgram/day) for 48 hours after reperfusion. The AST, ALP, LDH and ET-1 concentrations were monitored RESULTS: The AST and ALP levels of the lipo-PGE1 group were significantly lower than those of the control group both at 1 hour and 48 hours after reperfusion. The LDH level in the lipo-PGE1 group was lower at 1 hour and 48 hours after reperfusion. But there was no statistical difference between the two groups. The baseline ET-1 concentration of the lipo-PGE1 group was eight times higher than that of the control group. The ET-1 concentration was elevated gradually in the control group. There was no significant difference between the two groups at 48 hours. There was no correlation between ET-1 concentrations and AST, ALP, LDH levels. CONCLUSION: This study demonstrated the hepatoprotective effect of the lipo-PGE1 against ischemia-reperfusion injury in canine partial liver allotransplantation. However, the baseline ET-1 level was eight times higher in the lipo-PGE1 group than that of the control group in spite of the hepatoprotective effects of the lipo-PGE1.

The incidence of ectopic pregnancy is increased since IVF-ET has started. The risk factors for ectopic pregnancy after assisted reproductive techniques are tubal abnormality, previous myomectomy, the number of transfered embryo, the technical aspects of embryo transfer, the amount of transfered medium and uterine reverse contraction after embryo transfer. Because of the possibility of combined pregnancy after IVF-ET, bilateral adnexal area should be examined by transvaginal ultrasonography at searching intrauterine gestational sac and also serial beta-hCG levels should be checked. We report a case of simultaneous left tubal and right ovarian pregnancies after IVF-ET with a brief review of literature.

We present the case report of a 72-year-old female in whom diaphragmatic eventration and secondary gastric volvulus developed 10 years after a left partial pneumonectomy for a bronchiectasis. Eventration of the diaphragm is defined as an abnormal elevation of an intact diaphragm. The abnormally wide subdiaphragmatic space provides the potential for a gastric volvulus, which results from the strong negative intrathoracic pulling force created by the potential subphrenic space and paradoxical movement of the diaphragm. Unless this strong negative force is first eliminated, gastropexy alone will lead to recurrence. Obliteration of the subphrenic space by colonic displacement is a simple and effective way of abolishing this negative subdiaphragmatic pulling force. Treatment of gastric volvulus requires immediate surgical repair to prevent subsequent necrosis and perforation, with surgical correction of the underlying anatomic abnormality being the treatment of choice for gastric volvulus. We experienced a case of gastric volvulus due to diaphragmatic eventration who was treated with colonic displacement.

Nitric oxide (NO) is synthesized within the adult and developing kidney and plays a critical role in the regulation of renal hemodynamics and tubule function. In the adult kidney, the regulation of NO synthesis is very cell type specific and subject to distinct control mechanisms of NO synthase (NOS) isoforms. Endothelial NOS (eNOS) is expressed in the endothelial cells of glomeruli, peritubular capillaries, and vascular bundles. Neuronal NOS (nNOS) is expressed in the tubular epithelial cells of the macula densa and inner medullary collecting duct. Furthermore, in the immature kidney, the expression of eNOS and nNOS shows unique patterns distinct from that is observed in the adult. This review will summarize the localization and presumable function of NOS isoforms in the adult and developing kidney.

The purpose of this study was to perform on the biological activity of Magnolia and Zizyphi fructus extract mixtures on the wound healing of defected rat calvaria. For the determination of the mixture ratio of two extracts for oral administration, preliminary experiments were performed with the mixture combination of 2000 and 3000microgram/ml of Magnolia extract, and also 20, 30, 200, 300, 2000 and 3000microgram/ml of Zizyphi fructus extract, respectively and divided into 6 groups. The combination of extracts mixture were tested on the enhancing effect of cellular activity. The effect of the extracts mixture on the cellular activity was evaluated using MTT method and measured on the results with optical density by ELISA reader. The ability to tissue regeneration of the extracts mixture was performed by measuring new bone and new connective tissue regeneration on the 5mm defected rat calvaria for 1, 2 and 3 weeks after oral administration of 2 different dosages groups : 10:1(0.1g/kg) and 10:1(0.5g/kg). It was employed the same dosages of unsaponifiable fraction of Zea Mays L as positive controls. Each group of rat was sacrificed and en bloc section for histological examination. The effect on the cellular activity of each mixture ratio showed significantly higher in 2000microgram/ml of Magnolia extract and 200microgram/ml of Zizyphi fructus extract group to compare with other groups. These preliminary results showed that appropriate mixture ratio of two extracts was 10:1 of Magnolia and Zizyphi fructus extract. Histological examination on the activity of tissue regeneration of each group showed that 2weeks and 3weeks specimens of 0.5g/kg of 10:1 extract mixture of Magnolia and Ziziphi fructus administrated rat calvaria revealed significantly more osteoid and new bone formation of defected calvaria with unification of defected area than the specimens of any other negative and positive controls. Even though the specimen administrated the same dosages of unsaponifiable fraction of Zea Mays L, positive controls, showed the trend that they promote significantly the repair of calvarial defect, their bone reparative activities were less inductive than the same dosages of Magnolia and Ziziphi fructus extract mixture. These results implicated that the mixture of Magnolia and Zizyphi fructus extracts should be highly effective on the wound healing of bony defected site and might have potential possibilities as an useful drug to promote periodontal tissue regeneration.

Castleman's disease is an atypical lymphoproliferative disorder of unknown origin. It has three histologic types (hyaline vascular, plasma-cell, and mixed) and two clinical types (localized and multicentric). Some systemic diseases may be accompanied with Castleman's disease, but it is unclear if Castleman's disease is relevant to rheumatoid arthritis. We experienced a case of Castleman's disease suffering from rheumatoid arthritis. A 25-year-old female with rheumatoid arthritis was referred to our hospital with a palpable mass lesion in the left upper arm. Excisional biopsy of the mass and arthroscopic synovectomy were performed, and the histological finding was compatible with hyaline-vascular type of Castleman's disease. Herein, we report this case along with brief review of relevant literature.

E-cadherin is a cell adhesion molecule that plays an important role in maintaining renal epithelial polarity and integrity. The purpose of this study was to determine the exact cellular localization of E-cadherin in pig kidney. Kidney tissues from pigs were processed for light and electron microscopy immunocytochemistry, and immunoblot analysis. E-cadhedrin bands of the same size were detected by immunoblot of samples from rat and pig kidneys. In pig kidney, strong E-cadherin expression was observed in the basolateral plasma membrane of the tubular epithelial cells. E-cadherin immunolabeling was not detected in glomeruli or blood vessels of pig kidney. Double-labeling results demonstrated that E-cadherin was expressed in the calbindin D28k-positive distal convoluted tubule and H(+)-ATPase-positive collecting duct, but not in the aquaporin 1-positive, N-cadherin-positive proximal tubule. In contrast to rat, E-cadherin immunoreactivity was not expressed at detectable levels in the Tamm-Horsfall protein-positive thick ascending limb of pig kidney. Immunoelectron microscopy confirmed that E-cadherin was localized in both the lateral membranes and basal infoldings of the collecting duct. These results suggest that E-cadherin may be a critical adhesion molecule in the distal convoluted tubule and collecting duct cells of pig kidney.
