The lymphangioma is a benign vascular tumor and, like hemangioma, represents a hamartomatous growths. The site of predilection include the head, neck. and axillae. Lymphangiomas tend to involve the bulbar conjunctiva as well as the eyelid and orbit. Histopathologieally three types of lymphangioma are encountered: demal, cavernous and cystit types. The clinical signs are proptosis, diffuse hematoma of eyelid and subconjunctival hemorrhage. Asymptomatic cases can be observed. The authors experienced a case of multiple lymphangiomas on the right supraorbital area in a 14-year-old man and reported light microscopic and electron microscopic findings of the lymphangioma.

Neuroleptic malignant syndrome is a rare, but potentially life-threatening adverse event associated with the use of neuroleptic agents. We describe the case of a 47-year-old schizophrenic woman who was treated with clozapine for years. The patient developed acute renal failure with pulmonary edema, and underwent mechanical ventilation and hemodialysis.

To elucidate the complex of insulin-like growth factor binding proteins (IGF-BPs) in short stature patients, we carried out a prospective study on three patients who were diagnosed as complete GH deficiency at the department of pediatrics from July 1992 to June 1993. The results were summarized as follows: 1) Two circulating IGFs complexed to specific binding protein existed in normal serum. Binding activity was found to be in the 150,000 molecular weight area (the large complex) and 50~60,000 molecular weight area (the small complex). 2) Binding activity for the large complex was seen to be dependent on advancing age, level of large IGF-BP3 complex peacked at the age of 15~16 years. 3) The binding activity for large complex diminished in three GH deficient patients and increased after hGH injection to near or above normal level. 4) Increased growth rate after GH treatment in GH deficient patient was closely related with increasing level of the large IGF-BP3 complex. Therefore we suggest that the large IGF-BP3 complex is regulated by GH. Estimating its serum level is useful for screening of GH deficiency and the monitoring of response to GH therapy.

Recently, methionyl-hGH was produced in the E. coil K-12, W3110 by recombinant DNA technology in Korea. In this paper, the clinical efficacy and immunogenicity of this GH were studied in 43 patients with growth hormone deficency.The subjects of this study were aged 4.3-18.5 years and each patient received GH 0.5-0.71U/kg week subcutaneously, 6-7 times a week for 1 year. During treatment, height, body weight and bone age were checked. Blood count, urinalysis, blood chemistry and thyroid hormonal concentrations were checked before and every 3 months. The measurement of IGF-1 was performed and assay of antibody against hGH was performed before and every 6 months.The height velocities significantly increased from 3.7+-3.0 cm/year to 11.0+-4.2 cm/year and 9.9+-3.2 cm/year at 6 and 12 months after GH therapy, respectively. The Height SDS were significantly improved after GH therapy with increasing ratio of bone age to chronological age from 0.60+-0.19 at pretreatment to 0.68+-0.16 at 6 month, 0.69+-0.16 at 12 month of therapy. The plasma IGF-1 levels significantly increased during treatment. Three out of 35 patients(8.3%) showed antibody against hGH after 1 year of treatment. Thoughout study, we could not observe any remarkable side effect with GH treatment.These results indicate that this E. coli derived methionyl recombinant growth hormone is effective in improving the index of linear growth in the children with growth hormone deficiency without significant side effect.

BACKGROUND:It has been reported that there is association between cyclosporine (CsA) nephrotoxicity and proteinuria. The aim of this study was to investigate the anti-proteinuric effects of green tea polyphenol (GTP) on CsA-induced acute renal injury in mice. METHODS:The mice (n=20) were divided into 4 groups (n=5/group); group 1 (control group) mice were intraperitoneally (IP) injected 0.9% saline, group 2 (CsA group) mice were IP injected CsA 50 mg/kg, group 3 (iNOS inhibitor group) mice were given in addition N(G)-nitro-L-arginine-methyl ester (L-NAME) 12 mmol/L by subcutaneous injection. Group 4 (GTP group) mice were given CsA by IP injection and GTP 100 mg/kg by subcutaneous injection. RESULTS:Urine protein significantly increased in group 2 (28.6+/-11.1 g/kg/day) compared to group 1 (9.1+/-5.5 g/kg/day, p<0.01) and significantly decreased in group 4 (11.2+/-8.8 g/kg/day, p<0.01) compared to group 2. Renal tissue malondialdehyde level of group 2 significantly increased compared to group 1 and significantly decreased in GTP group (p<0.01). CONCLUSION:This study proves that proteinuria of the CsA induced nephrotoxicity is associated with lipid peroxidation and nitric oxide production. GTP treatment has meaningful antiproteinuric effects through antioxidative effect in the kidney from CsA-induced acute renal injury.

The familial exudative vitreoretinopathy is an autosomal dominantly inherited disease and shows abnormalities of the retina and vitreous. It affects both eyes in most cases, but the involvement is often asymmetric. Thus it is important to screen familial members carefully, since they may have only mild, nonprogressive changes in the retinal periphery. It is important to know family history of the disorder and history of prematurity or oxygen supplementation, since the clinical features are most similar to retinopathy of prematurity. The authors experienced three cases of familial exudative vitreoretinopathy in a 2-year-old girl with cryotherapy and her father and her brother with asymptomatic familial exudative vitreoretinopathy that has retinal vascular avascular zone of peripheral retina.

PURPOSE: We investigated the correlations between the expression of claudin-1 and claudin-7 in clear cell renal cell carcinoma (clear cell RCC) and clinical parameters. MATERIALS AND METHODS: The subjects of this study were 119 patients with confirmed clear cell RCC between January 2000 and December 2007. Their RCC tissues were immunohistochemically stained for claudin-1 and claudin-7. The correlations between the expression of claudin and parameters such as sex, age, body mass index (BMI), tumor size, TNM stage, Furhman nuclear grade, postoperative distant metastasis, and cancer-specific survival were analyzed. RESULTS: Among the total 119 subjects, claudin-1 was expressed in 18 (15.1%) and claudin- 7 in 31 (26.1%). Claudin-1 was expressed in patients who were older (p=0.007), who had a greater tumor size (p=0.001), who had a higher pathologic T stage (p=0.009), who had preoperative distant metastasis (p=0.035), and who had a higher Furhman nuclear grade (p=0.004). Claudin-7 was expressed only in patients who had a higher Furhman nuclear grade (p=0.031). The risk of postoperative distant metastasis was associated with the expression of claudin-1 (p<0.001) but not with the expression of claudin-7 (p=0.668). The expression of claudin-1 and -7 was not associated with cancer-specific survival (p>0.05). CONCLUSIONS: In clear cell RCC, claudin-1 was expressed in patients who were older and who had a greater tumor size, who had higher T or M stages, and who had a higher Furhman nuclear grade. The expression of claudin-1 was associated with a higher risk of postoperative distant metastasis.
