About 40% of patients with diabetes mellitus develops to diabetic nephropathy, and these patients show increment of glomerular filtration rate and renal volume at early phase. 99mTc-DMSA SPECT (single photon emission computed tomography) can measure a functional renal volume because 99mTc- DMSA it is taken up by the viable proximal tubular cells located in the renal cortex. To evaluate the renal volume in early diabetic nephropathy, we compared functional renal volume between diabetic patients and control, renal transplantation donor. 99mTc-DMSA was injected intravenously and SPECT was done after 2 hours in 15 diabetic patients, 18 renal transplantation donors, and 2 patients with end stage renal disease due to chronic glomerulonephritis. In diabetic patients with creatinine clearance more than 30ml/min and proteinuria, right and left renal volume were 247+/-22ml/BSA(m2), 256+/-37ml/BSA (m2), which were greater than those of diabetic patients with normal renal function and without proteinuria, or renal transplantation donors(P<0.05). In conclusion, we measured the functional renal volume by 99mTc-DMSA SPECT. Renal volume of diabetic patients with proteinuria were larger than the volume of control group or diabetic patients with normal renal function and without proteinuria. 99mTc-DMSA SPECT was thought to be useful test a for the measurement of functioning renal volume.

We report a case of a 25-year-old woman with systematized epidermal nevi associated with alopecia universalis and onychodystrophy. The histopathologic examinations by light and electron microscopies of the epidermis of the trunk and scalp lesions showed epidermal nevus with characteristic features of epidermolytic hyperkeratosis. This is a rare case of systematized epidermal nevi associated with congenital alopecia universalis and onychodystrophy. Though there is no apparent gross skin lesion on the hair bearing area, the development of epidermal nevi can affect the hair and nail units which are derived from the common epidermal germinative cells.

Progressive zosteriform macular pigmented lesion(PZMPL) is a chronic pigmentary dermatosis similar to progressive cribriform and zosteriform hyperpigmentation(PCZH). This dermatosis described by Simoes in 1980 is characterized by a uniformly tanned macular pigmented lesion in a zosteriform distribution preceded by multiple pruritic macular pigmentation in a part of the dermatome for a period. PZMPL is not a fully understood disease entity but it is thought to be a variant of PCZH. It is differentiated from PCZH by accompanying pruritus as a prodromal symptom, a characteristic clinical course, and histological findings such as pigmentary incontinence. We report herein a case of PZMPL in a 17 year-old girl with the pigmentary skin lesion extending from the left forearm to the left chest along the Blaschkos line. The histological findings revealed increased melanin pigments in the basal layer and focal pigmentary incontinence in the upper dermis. To our knowledge, this case is the first report of PZMPL in korea thought to be the same case reported by Simoes.

Results from two in vitro assays, Pharmacia CAP system(CAP) and fluoroallergosorbent test(FAST), for detecting serum specific IgE to three allergens, mugwort, Derraatophagoides pteronyssinus, and eat epithelium, were compared with skin prick test(SPT) results in 53 atopie dermatitis patients with positive SPT and 25 non-atopic controls. Using SPT results as the reference standards, CAP achieved higher sensitivity than FAST in determination of three allergens. CAP for measuring total IgE and eosinophil cationic protein(ECP) was also compared with FAST and ECP radioimmunoassay(RIA), respectively. In comparison of two assays for total serum IgE, the values obtained with CAP were significantly higher than those with FAST. In comparison of CAP and RIA for measuring ECP, the values obrained with CAP were significantly higher than those with RIA and the differences between ECP values of two assays were significant in high ECP group(>8.3 micro gram/1). These results suggest that CAP is the preferred test and seems to be more appropriate method for detection of specific IgE and ECP in patients with allergic digeases.

BACKGROUND: Stratum corneum lipids serve as a water retainer as well as permeability barrier by forming a multi-lamellae structure in the stratum corneum. The major constituent of these lipids, ceramides, have been shown to be predominantly associated with both functions. OBJECTIVE: Exposure of human epidermis to ultraviolet(UV) irradiation leads to changes in the physiologic and biochemical features of the skin. In order to investigate the effect of UVB irradiation on the skin barrier function in hairless mice, transepidermal water loss (TEWL) and lipid composition of stratum corneum were evaluated in hairless mice. METHODS: Hairless mice were irradiated 3 times weekly for 3 weeks with suberythemal dose (0.6MED, Group I) and minimal erythemal dose(MED), Group II) of UB. The mice of Group III received high dose of UVB(3MED) on the back in a single exposure. The control was Group IV. TEWL measured by evaporimeter and lipid composition of stratum corneum appraised by high performance thin layer chromatography(HPTLC) were evaluated weekly for 3 weeks. RESULTS: 1. Each time it was measured, the values of TEWL in group I were lower than group IV, but the difference was not significant. The peak value of TEWL in group II was 8.2+/-1.56 g/cm/h on the 7th day. The increase in TEWL was markedly significant at this point(P<0.001). Although the values of TEWL on the 14th and 21th day in group E increased compared with those of the control group, the significance of the values decreased (P<0.05). 2. The peak value of TEWL in group III was 9.88+/-1.13 g/cm/h on the 2nd day, showed a markedly significant increase compared with that of the control group(P<0.001). The values of TEWL decreased to the level of the control group on the 14th day. 3. The lipid(cholesterol sulfate, ceramide and neutral lipid) and total lipid mass in group 1 were insignificantly larger than that of the group IV measured each time. On the 7th and 14th day, the amount of each three lipid and total lipid mass significantly increased (P<0.05). On the 21th day, the amount of ceramide and neutral lipid showed a significant increase(P<0.05), furthermore the total lipid mass increased pronouncedly(P<0.01) in group II. 4. The amount of the 3 kinds of lipid and total lipid mass in group III significantly increased compared with those of the control group on the 2nd day(P<0.05). After the 7th day, no significant difference of the lipid mass except neutral lipid compared with that of the control group was seen. Comparing the 2nd and 14th day, there was a significant decrease in the amount of ceramide and total lipid mass(P<0.05) CONCLUSION: These results results suggest that considerable amount of UVB irradiation given in single or repeated exposure causes the disruption of skin barrier function, but a compensatory increase of skin lipid, especially ceramide, protests it from further damage and also improves skin barrier function.

Disseminated superficial actinic porokeratosis (DSAP) has an autosomal dominant mode of inheritance with reduced penetration at young age, characterized by multiple superficial keratotic lesions surrounded by a slightly raised border. The aggrevation of the lesion by exposing UV light indicates that phenotypic expression of gene regluating DSAP is related to sun light. We observed a family of which 13 members had DSAP in 3 successive generations. They were grandrnother, two sons of her 3 offsprings, 2 grandsons and 8 granddaughters. Lesions of all cases were found on the sun exposed areas, especially, face, extremities and upper trunk but exceptionally one had a lesion on the unex posed area, abdomen below the iliac crest. The number of lesions of the individual patient were 12-116, and there appeared to be increasing number of lesions with age.

The patient was 29 years old male who has been suffering from long standing painless multiple brownish red papules and nodules on the left forehead since 10 years previously. Histopathologically, dermal vascular component consisted predominantly of irregularly shaped capillaries with greatly swollen, pleomorphic endothelial cells some of which protruded into the lumen. And many eosinophils and lymphocytic infiltrations were seen in the dermis. Direct immunofluorescence showed homogeneous or granular deposits of C, in the endothelial cell of the small blood vessels in the dermis.

It is the most important to select optimal culture conditions to promote safe embryo growth in the technique of human in vitro fertilization and embryo transfer. It has been shown that the addition of biologic fluids, such as blood serum, of various origins, improved fertilization and early cleavage rates in numerous species. The purpose- of this study is to attempt to measure developmental potential of mouse eggs fertilized and cleaved in Ham's F10 culture medium containing a chelating agent, EDTA and fetal cord serum. hi this study, we selected 40 female mice and 20 male mice, and investigated optimal serum concentration' for mouse embryo growth. Two cell stage mouse embryos were cultured in Ham's F-10 medium, Ham's F-10 medium with various concentrations of EDTA, or Ham's F-10 medium with EDTA and 10% human cord serum. Developmental ratios to morula in Ham's F-10 medium containing various concentrations of EDTA and/or 10% fetal cord serum were significantly higher than in unsupplemented Ham's F-10 medium (p<0.05). Developmental ratios to blastocyst in Ham's F-10 containing 10% fetal cord serum and 5011M or 100pM EDTA were significanldy higher than in unsupplemented Ham's F-10 medium (p<0.05). Developmental ratios to morula in Ham's F-10 containing 10% fetal cord serum and 100,uM EDTA were significanitly higher than in Ham's F-10 with 10% fetal cord serum used commonly in many human IVF centers(p<0.05). Developmental ratio to blastocyst in Ham's F-10 containing 10% fetal cord serum and 100pM EDTA was significanity higher than in Ham's F-10 with 200pM EDTA(p<0.05).

This study was performed to investigate the clinical efficacy of intralesional recombinant interferon-γ (IFN-γ) in the treatments of warts, using a placebo comparison. Warts of each groups were injected with INF-γ containing 5×10⁶ IU/ml (high dose), 1×10⁶ IU/ml (low dose), or distilled water for injection as placebo, respectively, twice weekly for three weeks. The final therapeutic efficacy was determined on the fourth week after the beginning of therapy. Among the 74 patients with periungual warts, plantar warts, or warts of other sites, complete clearing of the treated warts at week four occurred in 56% of the 36 patients receiving the high dose IFN-γ compared to 30% of the 53 receiving the low dose IFN-γ and 17% of the 36 receiving the placebo. Marked improvement showing 75% or greater regression of wart lesions was noted as 89% of patients receiving the high dose INE compared with 55% receiving the low dose IFN and 50% receiving the placebo. The group of patients with warts of other sites showed the best response. The group receiving the high dose IFN experienced some adverse effects more frequently or more severely than the group receiving low dose IFN. However, the effects were relatively tolerable to the patients. Therefore, intralesional injection of the high dose IFN-γ may be more useful in treating warts than a low dose IFN-γ.
