The authors attempted to examine the distribution of S-100 protein in the human fetal skin. Immunohistochemical staining(ABC rnethod) using anti-S-100 antibodies was carried out on skin specimens taken from 11 human fetuses ranging from 9 weeks to 27 weeks of estimated gestational age. At 9 weeks of estimated gestational age, the embryonic epidermis consisted of three cell layers,' the basal layer, intermediate layer and periderm, all of them being stained for S-100 protein. But after 18 weeks, the basal layer changed to be negative. Granular and cornified layer's, beginning their development at 22 weeks, were not stained for S-100 protein. Hair germ of 12 week-fetuses was recognized unstained as a bulge of basal cells. In fully differentiated structural components of the hair follicle after 18 weeks, the outer root sheath only was stained for S-100 protein whereas the inner root sheath, hair matrix cells and sebaceous glands were unstained. Eccrine gland germs developed at 12 weeks of embryonic life as undulation of the basal layer and were not, stained. And at 22 weeks, the secretory portion of the eccrine glands were formed in the dermis and stained for S-100 protein. Our present study suggests that the expression of S-100 protein can undergo considerable changes during ernbryonic differentiation in the epidermis and epidermal appendages.

In order to evaluate the cytogenetic hazard among hospital workers potentially exposed to low dose of radiation, the analysis of chromosome aberrations(CA) and sister chromatid exchanges(SCE) in lymphocytes were performed in 79 hospital workers and 79 non-exposed workers. The mean frequency of chromosomal exchange and deletion(respectively, 0.20X10-2/cell and 0.39X10(-2)/cell) in the exposed group were significantly higher than those(0.07X10(-2)/cell and 0.23X10-2/cell) in control group. The frequency of sister chromatid exchanges was 5.04/cell in the control vs. 6.57/cell in the exposed group. There were also significant differences in the mean frequencies of CA and SCE adjusted for age, sex, smoking, drinking between two groups. There were no evidence of significant increase of CA and SCE according to the department or duration of employment. But the frequency of cells having chromosome aberration was significantly higher in the exposed group than in the control group related to duration of employment. There was no dose-effect relationship between the cumulative doses and the frequency of CA and SCE. But in the case of last 1 yr cumulative dose, there were evidence of significant dose-dependant increase of chromosome type CA and percentage of cells with aberration. The result suggest that there is cytogenetic hazard in risk group like hospital workers handling low dose radiation. And the analysis CA and SCE are useful biological indicators for the exposure of low dose level of radiation.

PURPOSE: For prevention of renal scar, early diagnosis and treatement of acute pyelonephritis are important in children with febrile urinary tract infection. But it has been difficult to differentiate acute pyelonephritis from lower urinary tract infection. We have performed this study to evaluate the diagnostic value of 99mTc-DMSA renal scan and to clarify the relationship among acute pyelonephritis, vesico-ureteral reflux and renal scar. METHODS: We have studied 100 patients with febrile urinary tract infection, from September, 1993 to June, 1995 at the Pediatric department of Ewha Womans University, Mok-dong hospital. Acute phase reactants, causative organism, renal ultrasound, 99mTc- DMSA renal scan on the acute stage, voiding cystouretherogram after 1-2 weeks of treatement, and follow-up 99mTc-DMSA renal scan were evaluated. RESULTS: Ther results are as follows; 1) 57 patients (57%) had defect on 99mTc-DMSA renal scan and diagnosed as acute pyelonephritis. 2) Acute phase reactants, renal ultrasound had low accuracy. 3) VUR was found in 31 (56.1%) of 57 patients with defect which was significantly higher than the 4 (9.3%) of 43 patients without defect on 99mTc-DMSA renal scan. 4) On the follow up 99mTc-DMSA renal scan, 34.8% of defects recorvered, and 65.2% of defects developed renal scar. CONCLUSIONS: 99mTc-DMSA renal scan is a valuable method for early diagnosis of acute pyelonephritis in children with febrile urinary tract infection. It would contribute to evaluate the relationship between acute pyelonephritis, vesico-ureteral reflux and renal scar.

Impaired fasting glucose (IFG) is one of significant risk factors of developing diabetes. The persons with IFG are, thus, an important target group for primary prevention of diabetes. It is well known that plasma homocysteine concentration may be increased in poor folate nutritional status. Elevated level of plasma homocysteine is considered as a marker of enhanced oxidative stress. In addition, the protective effect against oxidative stress may be diminished in poor antioxidative nutrient status as vitamin C. It is, therefore, important to maintain adequate nutritional status of folate and vitamin C in the patients with type 2 diabetes or IFG. This study was performed to determine the effects of supplementation of folic acid or vitamin C on plasma concentrations of homocysteine, oxidized LDL, and lipids and on the activity of plasma anti-oxidative enzyme in patients with IFG. A total of 97 patients with IFG were participated voluntarily with written consents. They were divided into one of the four experimental groups; Control (C), Folatesupplemented (F), Ascorbate-supplemented (A), and Folate plus ascorbate-supplemented (FA). The subjects in C were taken placebo, those in F were supplemented 1 mg of folate, those in A were received 1,000 mg of vitamin C, and those in FA were given 1 mg of folate plus 1,000 mg of vitamin C daily for 4 weeks. No change in plasma concentrations of vitamin C, lipids, and oxidized LDL and the activity of GSH-Px were observed in vitamin C-supplemented group (A + FA) and folate-supplemented group (F + FA) compared to the placebo group (C + A). Only the folate-supplemented group (F + FA) had significantly increased average serum folate concentration and lowered plasma homocysteine concentration compared to the placebo group (C + A). Thus, it should be recommended the patients with IFG to increase folate intake through diets and, if it is not sufficient, to take folic acid supplements to prevent the development of complications induced by hyperhomocysteinemia as well as oxidative stress.

Purpose: Deodeok (Codonopsis lanceolata) is generally used in conventional medicines and is considered to have remedial properties to cure several diseases. However, application of the C. lanceolata bud as a novel food ingredient has not been fully explored. Hydrogen peroxide (H2O2) is associated with the production of oxidative damage that results in mutagenesis, carcinogenesis, and cell death. This study examines the neuroprotective effect of C. lanceolata bud extracts (CLBE) on H2O2 -stimulated apoptosis in SH-SY5Y cells. Methods: C. lanceolata bud of length 10 to 15 cm was collected and extracted using 70% ethanol. Cytotoxicity was evaluated by the EZ-cytox reagent, measurement of lactic dehydrogenase (LDH) release and reactive oxygen species (ROS). The morphological changes of the nuclei were determined using the Hoechst 33258 dye. Enzyme activities were analyzed using the caspase activity assay kit. Related protein expressions were quantified by the Western blot immunoassay in H2O2 -stimulated SH-SY5Y cells. Results: Cell viability, LDH release and ROS generation, demonstrated neuroprotective effects of CLBE in H2O2-stimulated SH-SY5Y cells. The occurrence of apoptosis in H2O2-stimulated cells was confirmed by caspase activity, which was increased in H2O2-stimulated SH-SY5Y cells compared to the unexposed group. Pretreatment of CLBE was observed to inhibit the H2O2–stimulated apoptosis. In addition, exposure to CLBE resulted in increased expression of the Bcl-2 (B cell lymphoma 2) protein and decreased expression of the Bax (Bcl2 associated X) protein. Conclusion This study shows that exposure to CLBE alleviates the H2O2-stimulated neuronal damage in SH-SY5Y cells. Our results indicate the potential application of CLBE in neurodegenerative disease therapy or prevention.

In this study, we aimed to investigate the neuroprotective effects of caffeic acid phenethyl ester (CAPE), an active component of propolis purified from honeybee hives, on photothrombotic cortical ischemic injury in mice. Permanent focal ischemia was achieved in the medial frontal and somatosensory cortices of anesthetized male C57BL/6 mice by irradiation of the skull with cold light laser in combination with systemic administration of rose bengal. The animals were treated with CAPE (0.5–5 mg/kg, i.p.) twice 1 and 6 h after ischemic insult. CAPE significantly reduced the infarct size as well as the expression of tumor necrosis factor-α, hypoxiainducible factor-1α, monocyte chemoattractant protein-1, interleukin-1α, and indoleamine 2,3-dioxygenase in the cerebral cortex ipsilateral to the photothrombosis. Moreover, it induced an increase in heme oxygenase-1 immunoreactivity and interleukin-10 expression. These results suggest that CAPE exerts a remarkable neuroprotective effect on ischemic brain injury via its anti-inflammatory properties, thereby providing a benefit to the therapy of cerebral infarction.

Drug rash with eosinophilia and systemic symptoms (DRESS) syndrome is diagnosed by three criteria including cutaneous drug eruption, hematologic abnormalities, and systemic involvements. The hematologic abnormalities include presence of atypical lymphocytes or eosinophilia. The systemic involvements include lymphadenopathy, hepatitis, interstitial nephritis, interstitial pneumonia, or carditis. We experienced a 41-year-old female patient who presented DRESS syndrome at initial visit, but finally manifested with T-cell lymphoma. The patient complained of erythematous pruritic plaques with itching on her abdomen and thigh. There was no initiating factor and she was diagnosed with urticarial dermatitis. After treatment with antihistamine and systemic steroid, she recovered from skin lesion. However, 1 month later, she came to emergency department with aggravated skin lesion after taking nonsteroidal anti-inflammatory drug for 3 days. On admission, she showed a fever, skin rash, atypical lymphocytes in peripheral blood smear, and hepatitis. She was treated with systemic steroid under the impression of DRESS syndrome. Her symptoms began to improve, however, laboratory parameters were aggravated again. We performed bone-marrow biopsy because of her unusual progress. Finally she diagnosed with peripheral T-cell lymphoma and treated with allo-peripheral blood stem cell transplantation. In conclusion, we report a case of T-cell lymphoma which presented as DRESS syndrome. If patients with DRESS syndrome present lymphadenopathy and atypical lymphocytes, and do not respond to anti-inflammatory treatment, we should consider underlying lymphoproliferative disease.
