BACKGROUND: Arterial blood gas analysis are highly susceptible to preanalytic error due to improper method of obtaining or handling the blood sample before analysis. The error in measurement of blood gas analysis are loss of CO2 by exposure to atmospheric air, effect of anticoagulant itself, temperature difference between the experimental subject and the measuring electrode and metabolic change which occur between blood sampling and measurement. METHOD: To study the effect of the delay in estimation of blood gas and drawn blood on values of blood gas partial pressure and pH. Blood sample were divided into 2 groups according to the method of storage, group I stored at 24~25degrees C(room temperature) under anaerobic condition. ;group II stored at 0~4degrees C(refrigerator) under anaerobic condition. The samples were analyzed by time interval through 180 minutes in each group. RESULTS: The result were as follows: 1) PaO2 decreased significantly after 10 mins in group I, whereas it decreased significantly after 20 mins in group II. 2) PaO2 increased significantly after 20 mins in group I, whereas it increased significantly after 120 mins in group II. 3) pH decreased significantly after 60 mins in group I, whereas it decreased significantly after 120 mins in group II. 4) No significant changes of bicarbonate and SaO2 were noted in each group CONCLUSION: From above results, it would be advisable to analyze the sample in a short period of time or to store in a refrigerator when the measuring will be delayed. So we highly recommend that blood gas analysis should be performed as soon as possible after sampling, especially within 10 minutes.

Cutis naarmorata telangiectatica congenita(CMTC) was first lesribed by Van Lohuizen in 1992. Cases of CMTC were reported later under various names, includir gan Lohuizens syndrome, congenital generalized phlebectasia. congential phlebectasia and reticulatever scular nevus. It is charaterized by persistent livedo reticularis, telangiectasia and phlectnsia from birch hand atrophy and superficial ulceration of the overlying skin are uncornmonly encountered. They have a steady improvement with time, however various congenital abnormalties, such as varicosities, hen ariomas, hypoplasia or hypertrophy of soft tissue and bones, rarely generalized congenital fibrornatos ectal and genital anomaliies may be associated in approxirnately 50 percent of patients. In case 1, the patient was 45-day-old female infant with reticulated mottling and atrophy of the skin on the right leg. In case 2, the patient was 30-day-old male infant who depressed, bluish, and reticulated patches on the both upprarms, right side trunk, buttock and loen leg. Decreased circumferences of the affected extremities vas observed in case 2. No other assotated anomalies were found in physical and X-ray examinatiorwlin both cases. The skin biiopsy of bothed similar findings, which revealed mild dilatation and proliferation of capillaries, mild inflammatoryel infiltration and extravasated red blood cells in the dermis. The clinical follow-up, alneast all of th lisions disappeared spont.anously in 1 year at case 1, and some of lesions also disappeared in 3 month, 11 case 2. In addition, we reviewed and summerized the reported cases in Korea.

Eccrine carcinoma does not have a characteristic clinical appreranc, but does have a high incidence of metastatic spread. It may arise anywhere in the skin. The microscopic patterns that of an adenocarcinoma, which may be confused with metastatic adenocarcinoma. In the classical type the histologic features varies from fairy well-differentiated tubular structures in some areaslo anaplastic carcinoma in other areas. The patient was a 51-year-old man who showed a painful, tender, right red-calored, 4 x 5crn-sized tumor mass on the right angle of the lower lip for ten years. In the diological examinations multiple metastatic foci were seen on both lung fields, Histopathologic findings of the skin and lung biopsy specimens revealed that of the classic type of eccrine carcinoma like the bove descriptions. Immunocytochemical studies showed a positive reactivity to anti-cytokeratin anti-ibody, anti-CEA antibody, and anti-S-100 protein on the skin and lung biopsy specimens and no he reactivity to anti-S-100 protein on the lung mass. Electronrnicroscopic findings revealed eccrine glaidlar structures such as nunierous mitochondria and dense core granules in the cytoplasm of neoplastic cells. We report a case of eccririe carcinoma with lung metastases baed on the clinical, radiological and histologic findings.

Weber-Christian diaease is characterized by recurrent crops of subcutaneous nodules or plaques which occur during febrile periods and usually has spontaneous regression. Since the earlier case reports there have been instances of nodular panniculitis affecting visceral fat as well as the subcutaneous tissue. Death may rarely occur follow ing visceral involvement. We experienced a fatal case of Weber-Christian disease in a 32 year old female, who had prominent hepatomegaly and leukopenia accompanied by various general symptoms such as nausea, vomiting, abdominal pain, and cough. This case also had unusually large erythematous swelling of the face and aMomen in addition to multiple subcutaneous nodules in the extremities and trunk.

An etiologic agent in seborrheic dermatitis is now considered to be due to Pityrosporum ovale. The connection between the yeast and the disease has been clearly dernonstrated in a number of patients treatd with antifungal agents. However, the fact, that Pityrosporum ovale (Pityrosporum orbiculare) belongs to the normal human cutaneou. flora makes it difficult, to explain the role of the organism in seborrheic dermatitis. In this clinical study, twenty eight subjects were divided into two group by treatment regimen of topical 2% ketoconazole shampoo(TKS)and 0.3% prednisolone valerate solution (PVS). Before and during the four weeks treatment periods, the number of Pityrosporum ovale on the scalp were evaluated by scrub Giemsa staining method, which estimat,ed by score scale, under direct. microscopic examination. Also clinical symptoms including erythema, scales and itching were recorded by scores every week and compared between two treatment group. Topical application of 2% ketoconazole shampoo(TKS) is a very effective treatment regimen to reduce the yeasr cell score(from 5.8+1.3 to 1.8+1.4) than PVS(from 6.4+1.3 to 3.5+1.5), significantly(p<0.05). So the results of this study acconsistent with the view that density of Pityrosgourum ovale plays a role in the cause and course of seborcheic derrnatitis on the scalp. And antifungal agent(TKS) shows favorable effects ori tnis disease clinically and mycologically.

BACKGROUND: Diabetes mellitus is a heterogeneous group of disorders characterized by high serum glucose levels and by disturbances of carbohydrate and lipid metabolism. There are many cutaneous signs of this common endocrinopathy, such as nercobiosis lipoidica diabeticorum, diabetic bullosis, shin spot, diabetic pruritus, etc. OBJECTIVE: In this study, we investigated whether extracellular matrix gene expression in cultured skin fibroblast is influenced by insulin and Insulin-like growth factor-I(IGF-I). METHOD: Total RNA was isolated from insulin or IGF-I treated human skin fibroblasts. The Northern blot and slot-blot hybridization were then conducted. RESULTS: The mRNA levels of pro α1(I) collagen, pro α1(I11) collagen, fibronectin in insulin and IGF-I treated normal skin fibroblasts increased compared with untreated normal skin fibroblasts. CONCLUSION: Our results show that insulin and IGF-I stimulate collagen formation in normal skin fibroblast at physiological concentrations. Therefore, these demonstrate that insulin can modulate the expression of extracellular matrix gene.

BACKGROUND: Although actinic keratosis and Bowens disease ar considered as carcinoma in situ, most of them are biologically benign and dont progress to invasive squamous cell carcinoma. It is little known why they take the benign courses and which factors are involved in the tumorigenesis. Keratoacanthoma, self-regresi;ing benign tumor, may be sometimes or fused morphologically with well-differentiated squamous cell carcinoma. So it is necessary to find a useful marker to help us distinguish them. OBJECTIVES: We performed this study to gain a better understani ling of biologic behaviour and tumerigenesis of epidermal keiatinocytic neoplasms. METHODS: We investigated the expression of p53 protein and priliferating cell nuclear antigen (PCNA) by an immunohistochemical method on the formalin-fixed, araffinembedded tissue specimens of epidermal keratinocytic neoplasms. RESULTS: Fourteen out of 20 cases of squamous cell carcinoma(70.0%), 14 out of 22 cases of actinic keratosis(63.6%), and 13 out of 20 cases of Bowens disease(65.0%) showed p53 protein expression, but keratoacanthoma was negative. All the tumors studied sho ved significantly increased numbers of PCNA-positive eells when compared with normal epidermis and characteristic distribution pattern. of PCNA-positive cells. Most cases of actinic keratosis exhibited the basal dysplastic pattern, but Bo wenoid variants showed diffuse dysplastic pattern. Karatoacanthoma revealed the marginal pattern and Bowens disease showed the diffuse dysplastic pattern. Well-differentiated squamous cell carcinoria showed the basal dysplastic pattern, while poorly differentiated squamous cell carcinoma revealed d ffuse dysplastic pattern. CONCLUSION: Our results suggest that p53 mutation is a common and early genetic change in the epidermal tumorigenesis and may be used as a good marker for malignan transformation, but it does not seem to correlate with the biollagic behavior or prognosis of epidermal neoplasms. PCNA, which is considered as a proliferation-relaited marker, was expressed with chavaceristic distribution patterns according to the type of tumors, but the frequency of PCNA expression is unlikely to reflct the malignant potential of epidermal neoplasms.
