The PFAPA syndrome is characterized by periodic fever, malaise, aphthous stomatitis, pharyngitis and cervical lymphadenitis without long-term sequelae. It has been known as one of the cause of periodic fever in children. Because there is no specific laboratory findings, the diagnosis of PFAPA syndrome is not only made by exclusion of diseases which are related to the other causes of periodic fever, but also made by a careful history and characteristic clinical manifestations. The dramatic response to the single oral dose of corticosteroid is unique to this syndrome. The PFAPA syndrome tends to be resolved without any long-term adverse sequelae. We have reported a 3 year old boy who was diagnosed as having PFAPA syndrome by episodes of periodic fever for 3 months and by excluding other febrile diseases. He was treated with oral prednisolone and his symptoms had been improved dramatically.

A 7-year-old spayed female domestic shorthair cat was referred for chronic intermittent vomiting. The frequency of vomiting increased recently, and the cat showed anorexia at presentation. There were no remarkable abnormalities on the blood analyses and diagnostic imaging. However, the endoscopic examination revealed focal erosions of the gastric body mucosa, and subsequent multiple biopsies were obtained. Histopathologic examination indicated mild to moderate lymphocytic gastritis. The vomiting was completely disappeared 7 days after the administration with prednisolone (PDS). However, because of side effects caused by the long-term PDS administration, cyclosporine was added on the prescription with tapered dose of PDS. The dog's condition improved with continued cyclosporine treatment, and no further vomiting and anorexia episodes have been noted. This case describes the successful management with administration of cyclosporine in feline lymphocytic gastritis.

A 15-year-old, spayed female Maltese dog weighing 2.80 kg was referred with seizure of unknown origin. At presentation, serum biochemistry showed marked hypoglycemia (46 mg/dL; reference interval [RI], 65-118 mg/dL). There were, however, no abnormalities on electrolytes, complete blood counts, urinalysis, survey radiographs, and abdominal ultrasonography. In the adrenocorticotropic hormone (ACTH) stimulation test, pre-ACTH and post-ACTH cortisol concentrations were within normal reference ranges. Serum insulin level was normal and fructosamine level was slightly lower than reference ranges. The clinical signs, including seizure and collapse caused by hypoglycemia, were gradually resolved with oral administration of prednisolone (PDS) twice daily. Forty five weeks later, serum biochemistry revealed hypoglycemia with markedly increased insulin level. On abdominal ultrasonography, increased heterogenous echogenecity with hypoechoic lesion was found within pancreatic parenchyma. Based on these findings, the dog was presumptively diagnosed to insulinoma. Hypoglycemic seizure was resolved with higher dose of PDS (1 mg/kg, q12h). At 688 days after first presentation, the patient was still alive without recurrence of hypoglycemic seizure. This case describes long-term management with PDS monotherapy in a Maltese dog with insulinoma.

PFAPA (periodic fever, aphthous stomatitis, pharyngitis, cervical adenitis) syndrome is one of the causes of periodic fever in pediatrics with unknown etiology. It is characterized by abrupt onset of fever, malaise, aphthous stomatitis, pharyngitis and cervical adenitis without long-term sequelae. Laboratory findings of this sporadic and nonhereditary syndrome are so non-specific that the diagnosis is based on clinical findings. Oral prednisolone is quite effective in controlling the symptoms. We report a case of a 6-year-old girl who was diagnosed as having PFAPA syndrome after 2 years of episodes, by excluding other disease entities with similar clinical features. The patient was treated with oral prednisolone and her symptoms improved dramatically.

The Efficacy of SHI-1909 was investigated in comparision with predinisolone in acetic acid and Picrylsulfonic acid solution (TNBS)-induced rat inflammatory bowel disease (IBD) for 5 days. 7% Acetic acid and 5% TNBS solution were administered with polyethylene (P.E) tube inserted to rats intracolon, which causing colitis to the rats. The acetic acid and TNBS control group (the saline treated colitic rat) exhibited ulceration and inflammation of the distal colon with formation of granuloma and pathologic connections. We checked the inflammatory parameters like rat's weight, food intake quantity change during administration. After 5 days, we sacrificed the rats and checked the colon's length, ulcer and pathologic condition. Oral treatment with SHI-1909 resulted in significant recovery of macroscopic parameters like weight and diet intake change. Especially, SHI-1909 had a more potent effect than prednisolone on macroscopic colonic damage score. We can suggest that SHI-1909 could be a promising drug in the treatment of IBD.

Purpose : The aim of this study was to evaluate whether the incidence of relapse or nephritis might be influenced by the duration of corticosteroid therapy in children with Henoch-Schonlein purpura(HSP). Methods : We retrospectively analyzed 186 children with a diagnosis of HSP in two major hospitals in Ilsan, Korea from the years 2000 to 2003. To evaluate whether renal involvement or relapse might be influenced by the duration of corticosteroid therapy in children with HSP, one pediatric nephrologist from hospital A, maintained corticosteroid therapy for at least 2 weeks(Group A, n=94). The other from hospital B used only during the symptomatic period(Group B, n=92). Results : There were no significant differences in age, sex, body weight, white blood cell count, hemoglobin, hematocrit, platelet count, serum protein and albumin levels between the two groups. The incidence of abdominal pain or arthralgia also did not differ between two groups. However, the duration of steroid therapy was significantly longer in Group A than in Group B and the cumulative dose of prednisolone was also higher in Group A than in Group B. The development of nephritis was more frequent in Group A. Conclusion : The longer duration of steroid use was not associated with the decreased rate of nephritis. Therefore, corticosteroids should be used carefully in a selected group of HSP children, and be tapered rapidly after control of the acute symptoms.

Multiple sclerosis (MS) is a demyelinating disorder that affects discrete areas of the CNS, including the optic nerves, in a quite variable relapsing-remitting fashion over a prolonged period of time. Although MS is usually considered to be a disease that affects peoples in early to middle adulthood, children do develop multiple sclerosis. The frequency of MS onset before the age of 15 years is 2.7-5% of all cases, while MS onset during infancy and early childhood was observed to be 0.2-0.7% of all cases. We report here on a Korean case of a relapsing-remitting MS female child who was treated with four rounds of intravenous methylpredinsolone pulse therapy and preventive Interferon-$\beta$-1b ($Betaferon^{(R)}$).

Purpose: The purpose of this study was to assess the therapeutic efficacy of methylprednisolone pulse therapy in children with IgA nephropathy and Henoch- Sch$\ddot{o}$nlein Purpura (HSP) nephritis combined with proteinuria. Methods: We retrospectively reviewed the clinical records of 21 patients who were diagnosed with IgA nephropathy and HSP nephritis based on percutaneous renal biopsy. Of the 21 patients, 15 were diagnosed with IgA nephropathy and 6 were diagnosed with HSP nephritis. They had mild to severe proteinuria at the time of diagnosis or during follow-up. Group 1 (n=7) received methylprednisolone pulse therapy three times every couple of months, and Group 2 (n=14) received oral steroid therapy. The follow-up periods for Group 1 and 2 were 14.0 (9-54) months and 26.5 (14-34) months, respectively. There was no significant difference in the follow-up duration between the two groups. Results: The average age at diagnosis and biopsy was lower in Group 1 compared to Group 2, but it was not significantly different. At admission, all patients in both groups had hematuria and 5 patients (71.4%) of Group 1 and 14 patients (100 %) of Group 2 had proteinuria. Before treatment, there was no significant difference of spot urine protein/creatinine ratio between the two groups. During followup, 7 patients of Group 1 (100%) and 10 patients of Group 2 (71.4%) showed complete improvement of proteinuria and the spot urine protein/creatinine ratio in Group 1 was significantly lower than Group 2. Conclusion: In patients with IgA nephropathy and HSP nephritis with proteinuria, methylprednisolone pulse therapy was more effective than oral steroid therapy in the reduction of proteinuria. To investigate the effects on long-term prognosis, large-scale prospective studies are needed.

The dissolution profiles of the seven branded prednisolone tablets were determined by means of available compendium. Those tablets were stored at $40^{\circ}C,\;50^{\circ}C\;and\;60^{\circ}C$ for 15, 30 and 60 days respectively. Under the stress conditions, the dissolution efficiency showed significant changes. It is considered that the determination of shelf life of drug from these aging effects is possible because the dissolution data followed a logarithmic distribution. There were no substantial differences of dissolution between two prednisolone formulations with different particle size not larger than $100\;{\mu}m$. The effect of two starches (corn and potato) on the rate of dissolution of prednisolone from dosage form was also investigated. All marketed tablets met the requirement of the established compendium.

A convenient high performance liquid chromatographic method for the quantitative determination and content uniformity of prednisolone in tablets is described. The prednisolone was chromatographed using a ${\mu}-Bondapak\;C_{18}$ column and the eluent 70% MeOH at a flow rate 1. 0ml/min. Diethylstilbestrol was used as an internal standard. The UV detector response at 254nm was linear over a range of $10{\sim}60{\mu}g/ml$ under conditions of the analysis. Reproducibility studies gave relative standard deviations of $0.3{\sim}0.5%$.
