Twenty-nine cases of unicameral bone cyst developed in long bone of children have been treated and followed up for 4.5 years in average form Department of Orthopaedic Surgery, Guro Hospital, Korea University, College of Medicine since September, 1983, Treatment for those lesions differed to form largely two groups, one of which consised of insillation of Methyl-prednisolone for non-weight bearing bones(12 humeri) and the other of curettage and autogenous bone graft for weight-bearing bones(7 femur). Methl-prednisolone group required repetition of instillation for 3.5 time in average spanning over 4 years until cloudy obliteration occurs. Curettage and bone graft had healed in 3 year 6 months' time in average. There were neither recurrence nor pathologic fractures of the lesions with the latter group. Immobilization period was virtually non with Methyl-prednisolone group and 4-6 weeks by hip spica with curettage and bone graft group. As conclusions, It seems confirmed that treatment strategy of unicameral bone cyst consisted of Methyl-prednisolone instillation for humerus lesions and early curettage and bone graft for femur lesions is applicable as guideline having solid ground in clinical experiences.

The aim of this study was to gain information on the effects of the crystal form of corticosteroids on the topical anti-inflammatory activity. Two different crystal forms, Form A and Form B, of the drugs of prednicarbate, hydrocortisone, betamethasone 17-valerate, prednisolone, and methyl prednisolone were prepared and their topical anti-inflammatory activities were measured using arachidonic acid induced ear edema assay in mice. Two crystal forms of the drugs showed differences in anti-inflammatory activity. Among the drugs examined, Form B of prednicarbate and betamethasone 17-valerate showed significantly more potent anti-inflammatory activities as compared to their Form A.

Purpose : Recently, clinical trials of steroid add-on therapy were reported with variable results in Kawasaki disease. We analyzed the clinical outcomes of patients at high risk of with Kawasaki disease(${\geq}4$ points of Harada score) treated by three commonly used different treatment regimens, with or without corticosteroids. Methods : Medical records of 96 children with Kawasaki disease treated with one of the threee regimens were reviewed retrospectively. Regimen 1 was aspirin(100 mg/kg/day) plus intravenous gamma globulin 2 g/kg single dose; regimen 2, aspirin(100 mg/kg/day) plus intravenous gamma globulin 1 g/kg single dose; regimen 3, regimen 2 plus prednisolone(2 mg/kg/day), followed by tapering two weeks and pulse therapy of methyl prednisolone performed in cases of retreatment. Also low dose aspirin was given in all three regimens for eight weeks after the acute phase. The cardiovascular and laboratory evaluations were performed on acute phase, immediate after acute phase, and subacute phase, eight weeks after treatment. Results : The frequency of coronary artery lesions and laboratory findings in the three different regimens were similar. The more rapid control of fever after treatment was noted in regimen 3. Furthermore the frequency of retreatment was decreased in regimen 3 compared to the other two regimens. Conclusion : Steroid add-on therapy showed some beneficial outcome compared to conventional treatment regimens. The role of steroid in the treatment of Kawasaki disease should be reassessed in systemic manner.

Pneumocystis carinii (Pc) is an important opportunistic pathogen of immune compromised hosts, and is known to infect various animals. The present study observed the infection status of 6 mammals and 3 strains of albino rats with Pc after suppression of their immunity. Methyl-prednisolone was injected once a week and tetracycline was supplied with water for 5 to 21 weeks. Hamsters, guinea pigs, rabbits, dogs, cats and pigs were negative by impression smear, and only the rats were found infected by Pc. All of the three strains of rats, Sprague-Dawley(SD), Wistar(W) and Fisher(F), were infected by Pc but W rats showed heavier degree of infection in earlier period than F or SD rats. The present findings suggest that W rat is the best among the animals used in the present study for production of Pc.

Purpose: This study investigated predictors of unresponsiveness to second-line intravenous immunoglobulin (IVIG) treatment for Kawasaki disease (KD). Methods: This was a single-center analysis of the medical records of 588 patients with KD who had been admitted to Asan Medical Center between 2006 and 2014. Related clinical and laboratory data were analyzed by univariate and multivariate logistic regression analyses. Results: Eighty (13.6%) of the 588 patients with KD were unresponsive to the initial IVIG treatment and received a second dose. For these 80 patients, univariate analysis of the laboratory results obtained before administering the second-line IVIG treatment showed that white blood cell count, neutrophil percent, hemoglobin level, platelet count, serum protein level, albumin level, potassium level, and C-reactive protein level were significant predictors. The addition of methyl prednisolone to the second-line regimen was not associated with treatment response (odds ratio [OR], 0.871; 95% confidence interval [CI], 0.216-3.512; P=0.846). Multivariate analysis revealed serum protein level to be the only predictor of unresponsiveness to the second-line treatment (OR, 0.160; 95% CI, 0.028-0.911; P=0.039). Receiver operating characteristic curve analysis to determine predictors of unresponsiveness to the second dose of IVIG showed a sensitivity of 100% and specificity of 72% at a serum protein cutoff level of <7.15 g/dL. Conclusion: The serum protein level of the patient prior to the second dose of IVIG is a significant predictor of unresponsiveness. The addition of methyl prednisolone to the second-line regimen produces no treatment benefit.

Anti-inflammatory glucocorticoid (GC) derivatives have been clinically used in immune-malfunctional diseases for their immunosuppressive activity. However, there is still a lack of knowledge on the relationship between anti-inflammatory and immunosuppressive activities. In order to compare immunosuppressive activities with the known anti-inflammatory activities of the GC derivatives, eight clinically used GC derivatives including hydrocortisone, prednislone, 6$\alpha$-methyl prednisolone, triamcinolone, dexamethasone, betamethasone, triamcinolone acetonide and fluocinolone acetonide were selected, and lymphoblastosis inhibition and plaque-forming cell (PFC) response in mice were studied as immunological parameters. In Con A-induced lymphoblatosis inhibition invitro, all derivatives showed potent inhibition $IC_{50}$ values of the derivaties except methyl prednisolone and triamcinolone were less than $10^{-7}$M and good dose dependency was obtained. This result was well correlated with that of their anti-inflammatory potencies obtained. This result was well correlated with that of their anti-inflammatory potencies and their receptor binding affinities. However, in PFC response, consistent result were not obtained. Total numbers of PFCs per spleen were decreased by some derivatives, but numbers of PFCs per $10^6$ cells were not decreased by systemic administration of but numbers of PFCs per $10^6$ cells were not decreased by systemic administration of GC at the dose of 0.05 mg/mouse. Furthermore, at the dose of 0.1 mg/mouse, numbers of PFCs per $10^6$ cells were found to be increased, although total PFCs per spleen were decreased.

Single subcutaneous injection to SD rats of both sexes was performed to investigate the acute toxicity of new skin allergy-remedy ointment, Banaron. Banaron is composed of lidocaine hydrochloride, chloro-pheniramine maleate, prednisolone acetate, chlorohexidine hydrochloride, methyl salicylate, 1-menthol and d-camphor. The results were as fellows. $LD_{50}$, /TEX> values of Banaron were 8373.6 mg/kg for male and 8260.1 mg/kg for females. Death occurred within 24 hours after administration at doses up to 6600 mg/kg. The main cause of deaths seemed to be respiratory disturbance. General symptoms decreased of activity and respiratory rate, salivation, tremor and loss of consciousness which were commonly observed by some survived animals and all dead animals. No significant gross findings of internal organs and body weight changes in treatment groups in comparison with these of control group were observed at the maximum dose levels in Banaron.

Henoch-Sch$\ddot{o}$nlein purpura can result from exposure to an antigen after infection with several types of organisms. However, Henoch-Sch$\ddot{o}$nlein purpura caused by a primary Epstein-Barr virus infection has been rarely reported. Here, we report the case of a 32-month-old female patient who presented with Henoch-Sch$\ddot{o}$nlein purpura. Based on abnormal liver function test results and positive results for Epstein-Barr virus infection markers, a diagnosis of Epstein-Barr virus hepatitis manifesting as Henoch-Sch$\ddot{o}$nlein purpura was made. Treatment with methyl-prednisolone and hydration improved the symptoms, and a switch to oral steroids was effective in completely alleviating the purpura. No recurrence was noted and no liver function abnormalities were detected during the follow up period.
