Congenital dislocation of the hip has been known as one of the most common congenital anomalies in the orthopedic field since the time of Hippocrates (460-357 B.C.). The occurence of C.D.H. in twin babies is extremely rare thus few if any papers have been reported. During the period of January 1971 through June 1976 the authors have treated a total of 49 cases as inpatients. Two of these were twin babies. In both cases the hip was surgically reduced and followed by open reduction and femoral derotation osteotomy. Clinically and radiologically the results were good during the duration of follow-up seven months after operations.

The distribution of transforming growth factor-α (TGF-α) and epidermal growth factor (EGF) in developing mouse embryos of gestational age 8 to 15 days was immunohistochemically (ABC method) studied to investigate the differential expression of these growth factors. Paraffin embedded sections were immunostained with antibodies for TGF-α and EGF. Staining of TGF-α was observed in several organs derived from endoderm, mesoderm and ectoderm in 9-day-old mouse embryos, such as in the heart, optic pit, head mesenchyme, neural tube and primitive gut, and the staining became more intense in 10 to 15-day-old mouse embryos. The staining of EGF was seen in the heart and primitive gut derived from mesoderm and ectoderm respectively, in 9-day-old mouse embryos, but it was observed in other organs as well in 10 to 15-day-old embryos although the intensity was weaker. In the development of heart, immunoreactivity for TGF-α was more intense than EGF, which suggests more active involvement of TGF-α. In the lung, TGF-α staining was observed both in the bronchus and lung bud, whereas EGF staining was seen only the bronchus. In the nervous system, TGF-α was expressed more extensively and more intensively than EGF. In the developing skeletal system, TGF-α staining was stronger and the expression was observed at earlier stage compared with EGF. These results indicate that the activity of TGF-α is more potent than EGF in the development of mouse embryo in general, especially, in the development of mouse heart, nervous system, mesenchyme and skeletal system.

The hyperosinophilic syndrome (HES) commonly involves liver and spleen but only a few literature has reported the imaging features. In this article, we present the imaging features of the liver and spleen in HES patients together with clinical and laboratory features. This study included 5 HES patients with hepatic involvement. Extensive laboratory tests including multiple hematologic, serologic, parasitologic, and immunologic examinations were performed. Imaging studies included CT, ultrasound (US) of upper abdomen and hepatosplenic scintigraphy. All patients were periodically examined by laboratory and imaging studies for 4 to 24 months. The common clinical presentations were weakness, mild fever, and dry cough. All patients revealed leukocytosis with eosinophilia of 40 to 80% and benign eosnophilic hyperplasia of the bone marrow. The percutaneous biopsy of the hepatic focal lesions performed in 2 patients showed numerous benign eosinophilic infiltrates and one of them revealed combined centrilobular necrosis of hepatocytes. All cases revealed hepatomegaly with multiple focal lesions on at least one of CT, US, or scintigraphy. These findings completely disappeared in 2 To 6 months following medication of corticosteroid or antihistamines. The HES involved the liver and CT, US, or scintigraphy. These findings completelydisappeared in 2 to 6 months following medication of corticosteroid or antihistamines. The HES involved the liver and CT, US, or scintigraphic studies showed hepatic multifocal lesions with hepatomegaly. Differential diagnoses of these findings should include metastatic disease, lymphoma, leukemia. candidiasis or other opportunistic infections.

Balloon cell malignant melanoma (BCMM) is a rare histologic variant of malignant melanoma, which is composed either predominantly or entirely of large clear or foamy cells. The incidence of balloon cell malignant melanoma is about 0.15% of all cutaneous malignant melanomas. Recently, we experienced a case of cutaneous balloon cell malignant melanoma in the right lower abdomen with right inguinal and both axillary lymph node metastasis in a 56-year-old man. The cutaneous lesion was 4.5 3.5 cm in size, a well-demarcated black nodular mass, involving abdominal skin and subcutaneous tissue. The tumor was histologically composed of two types of tumor cells: predominant clear cell and focal, pigmented spindle cell. The nodal lesion was composed entirely of clear cells. Both clear and spindle cells showed positive reaction for S-100 protein and HMB-45 on immunohistochemistry.

This study is concerned with the classifcation of Korean adult mandibular condyles on the basis of the shape of their anteroposterior view. The results were as follows ; 1. Morphological variations are classified into 4 groups. The percentage of each group has been : flat, 7.7% ; convex, 47.2% ; angled, 14.8% ; round, 30.3%. 2. The location of the highest point were as follows : in the lateral third, 15.5% ; middle third, 80.3% ; medial third, 4.2%. 3. The maximum transverse diameter and greatest height were 20.3±2.4mm and 6.5±1.5mm, respectively.

PURPOSE: This study investigated the effect of reducing cisplatin induced nephrotoxicity with DWP-04 that is the compound of Schizandrin C derivative biphenyldimethyl dicarboxylate (DDB), glutathione and selenium. For the purpose of observation is that how DWP-04 has influence on mechanism of reducing cisplatin induced nephrotoxicity with renal function test, free radical formation and detoxification enzyme system in renal tissue. METHODS: Five groups of rats were dosed with vehicle, cisplatin (2 mg/kg i.p.), cisplatin+DWP-04 (100, 200 mg/kg po), or cisplatin+sodium thiosulfate (200 mg/kg i.p.) daily for 4 weeks. RESULTS: Serum creatinine, lactate dehydrogenase and activity of hydroxy radical increased in the cisplatin group and suppressed in the cisplatin+DWP-04 group compared to the cisplatin group. The renal tissue concentration of lipid peroxidase and lipofuscin were increased in the cisplatin group compared to the other groups. The activity of aminopyrine N-demethylase, aniline hydroxylase, aldehyde oxidase and xanthine oxidase, of which free radical formation system in kidney was also decreased in the cisplatin+DWP-04 group compared to the cisplatin and cisplatin+sodium thiosulfate group. The activity of detoxification system of free radical, such as glutathione S-transferase, superoxide dismutase, catalase and glutathione peroxidase were markedly increased in the cisplatin+DWP-04 group than the cisplatin and the cisplatin+sodium thiosulfate group (p<0.05). CONCLUSION: It can be concluded that the mechanism of decreasing cisplatin-induced nephrotoxicity by DWP-04 is that the decreasing of the amount of lipid peroxide and lipofuscin in the renal tissue by increasing activity of the antioxidant defense system and the decreasing of reactive oxygen species by increasing detoxification enzyme activity.
