Adhesion around tendons of the hand and wrist and subsequent limitation of motion, is one of the major complications after tendon surgery. In addition to the tendon surgery such as tendon repair or graft, infection, open reduction of fracutres, and burn scar contracture could be the casuses of tendon adhesion. Tenolysis and adequate postoperative rehabilitation program, has been proved to be effective in preventing of adhesion, whatever the cause may be, if its continuity is maintained. In order to evaluate the efficiency and problems of tenolysis, we reviewed 37 fingers of 31 patients who had been treated by tenolysis at Seoul National University Hospital from 1981 to 1991. There were 20 men and 11 women, and the average age was 28.2 years(9-45 years). The causes of adhesion were various; 24 fingers(64%) after tendon repair or tendon graft, 3 fingers(8%) after infection, 4 fingers(10%) after treatment of fracture, 4 fingers(10%) after burn scar contracture, and the other 2 fingers(5%) after curettage of enchondroma. Involved tendon were flexor tendon in 28 fingers and extensor in 9. The average duration of follow-up was 17 months(13 months to 4 years). Active motion of involved finger was started within 2 days after operation. The Total Active Motion(TAM) after operation was average 213°(100°-260°), compared to 123°(40°-180°) before operation. According to Strickland formula which was modified by us, the postoperative results were excellent in 17 fingers, good in 9 fingers, fair in 6 fingers and poor in 5 fingers. In 24 cases who had tenolysis after repair or graft, 19 case(79%) were rated as excellent or good. But in 7 cases whose causes of adhesion were infection or burn scar contracture, only 3 cases(42%) were rated as excellent or good. Compairing the results between younger(less than 30 years of age) and older(more than 30 years of age) group, the younger group showed excellent and good in 8496 and the older group in 41%, The complications were tendon rupture in 3 fingers and minor infection in 2 fingers, respectively. In summary, tenolysis was considered as a useful procedure to improve function of tendon bound down in scar tissue. And the results were better in younger age group(p < 0.05) and in previous tendon repair or graft(p < 0.05) group.

OBJECTIVES: lschemic acute renal failure(ARF) is characterized by an abrupt and sustained decline in GFR within minutes to days after renal ischemia and not immediately reversed on restoration of renal blood flow. The typical delay of a few days to a few weeks suggests reversible parenchymal damage awaiting cell regeneration for functional recovery. Many potentially cell damaging factors, such as ATP depletion, plasma membrane phospholipid degradatian and superoxide-induced membrane damage, play a central part in ischemic injury. More recently, much attention has been focused on the role of calcium, especially ischemic cell injury and the possible therapeutic role of calcium channel blockers emerged from studies conducted several years ago. In the past, it was thought that activation of renin-angiotensin system plays a role in the pathogenesis of ARF. Now the role of angiotensin in human renal ischemia also appears to be controversial. The following study was done in order to investigate the effect of a calcium channel blocker, nifedipine, on gene expression of renin during acute ischemic renal injury. METHODS: The Sprague-Dawley rats were divided into 4 groups, group I(n=3) as the control, group II (n=3) as the sham operation group, group III(n=15) as the ischemic renal injury group without nifedipine pretreatment, and group IV(n=15) as the ischemic renal injury model by right nephrectomy and left renal artery clamping for 40 minutes with systemic nifedipine pretreatment(10mg/kg), 1n ischemic renal injury model(group III and IV), rats were further divided into three subgroups according to reperfusion time of 1,24,72 hours. The non-ischemic right kidney removed at the time of initial procedure served as paired control. Total renal RNA was extracted by Chomczynskis method and electrophoresis was done in a 1% agarose gel containing 2,2M formaldehyde. Northern was performed at 42degrees C with isotope labeled renin probe for 18 hours, Autoradiographs were obtained and quantitated by a densitometer measured at 530nm. RESULTS: 1) The expression of renin gene was markedly decreased after renal ischemia and slowly recovered to one half of the control level after 72 hours of reperfusion. 2) Renin gene expression pattern of ischemic renal injury with prior nifedipine treatment was similar to the ischemic group without nifedipine pretreatment. CONCLUSION: These findings suggest that the renin gene expression was markedly decreased after renal ischemia and slowly recovered. Systemic nifedipine pretreatment does not have a significant effect on gene expression pattern of renin in ischemic renal injury.

Kawasaki disease is an acute vasculitis of infancy and early childhood characterized by high fever, rash, mucositis, lymphadenopathy and coronary artery damage. The failure to indentify a causative organism using convetional culture and serological techniques, and the lack of response to antibiotics indicate that the disorder is probably not due to any known bacterial or viral pathogens. During the acute phase of the disease, the alterations of T and B cell functions, changes of cytokine and immunoglobulin levels have been reported. This study was performed to investigate the changes of immunoglobulins levels in patients with Kawasaki disease. IgG, IgA, IgM and IgG subclasses were measured using immunoprecipitation and EIA in the sera of patients with Kawasaki disease. The results were as follows: 1) Acute phase reactants such as CRP and ESR were significantly increased in Kawasaki patients compared to those in control patients(p<0.01). 2) Serum IgG levels in Kawasaki disease were markedly increased than those in control patients, while serum IgA and IgM levels showed no significant changes (P: No Significance). 3) IgG1 and IgG4 were predominantly increased increased in the sera of Kawasaki patients, while IgG2 and IgG3 were not significantly increased (P: No Significance). With these results, unidentified infectious organism with abnormal immune response could be suggested as an etiologic factor of Kawasaki disease.

T cell activation is a critical event for initiation and regulation of immune responses and inhibitors of such signaling pathways are clinically useful for the treatment of patients received allogratt and autoimmune disease. In the course of screening soil microorganisms from the forest of Cheju island in Korea for new immunosuppressive agent, one of Streptomyces species (CK-95441) was found to produce a new immunosuppressant, tautomycetin which also had antifungal activity. Tautomycetin showed the inhibition of T cell proliferation in murine mixed lymphocyte reaction (MLR) and T cell activation induced by concanavalin A. Tautomycetin also blocked the induction of IL-2 gene expression which was examined in Jurkat TAg cell line in which multiple NFAT-binding sites and minimal IL-2 promoter drive the production of B-galactosidase. Also, the level of inhibition in activation-induced IL-2 receptor expression by tautomycetin was greater than those by cyclosporin A measured by flow cytometry. But, Fas ligand-induced apoptosis in Jurkat cells was unaffected by tautomycetin which was measured by DNA fragmentation assay. These results suggested that tautomycetin will be able to be used as a potent immunosuppressive drug following organ transplantation.
