One hundred sixteen C57 BL mice were painted with either 8-MOP, 5-MOP or TMP solution in concentrations of 0.02%, 0.1%, and 0.5% each and UVA irradiated. Skin biopsies were performed at 1, 3, 5 and 7 weeks after LJVA irradiation. The results measuring the number, area, and perimeter of the melanocytes after topical PLJVA were higher in the TMP-painted group than in the 8-MOP or 5-MOP painted groups. In all groups, the weekly changes showed an increasing value through five weeks. In comparing the drug concentrations used, 0.1% of chemicals produced the same or higher values than 0.5%. There have been few studies on the effects of 5-MOP in photochemotherapy. In tho study 5-MOP produced a pigment-producing effect similar to 8-MOP. Therefore, if topical PIJVA with 5-MOP is used in clinical practice, we could expect a significant therapeutic effect in vitiligo.

This study was undertaken to investigate the recovery of epidermal Langerhans cells in relation to time after UVA irradiation through different amounts and ways of exposure in CH mice. We irradiated the ears of C2H mice with UVA 200J/cm2 and 400J/cm2 in a single dose at one time or 5 fractionated doses for 5 days and performed biopsies on the ears of the control and experimental groups after 2, 7, 14, 21days of irradiation and stained them with immunoperoxidase method. The results are summarized as follows, l. We observed a significant decrease in the number of the Ia-positive epidermal Langerhans cells in the single-dose-exposed group compared to the fractionated- dose-exposed group on 7th and 14th days irradiated with UVA 200J/cm. 2. There was no significant difference in the change in the number of the Ia- positive epidermal Langerhans cells until 21 days of exposure between the single- dose-exposed group and the fractionated-dose-exposed group irradiated with UVA 400 J/cm 3. In the group irradiated with UVA 2003/cm, the reduced number of the Ia-positive epidermal Langerhans cells returned to normal on the 14th day after irradiation in the fractionated-dose-exposed group and on the 21st day in the single- dose-exposed group. In the group irradiated with 400J/cm, the number returned to normal on the 21st day of irradition both in the fractionated-dose-exposed group and in the single-dose-exposed group.

Low Back Pain*

OBJECTIVE: The goal of this study was to determine the efficacy of prolotherapy in relieving the pain of patients with tendon or ligament laxity. METHOD: The subjects were 67 patients (40 male, 27 female) who were suffering from chronic musculoskeletal pain, excluding those with metabolic diseases that could influence the nature of the pain. The effect of the treatment was evaluated by checking the VAS score after a monthly injection of 15% dextrose solution injected around the patient's ligaments and teno-osseous junction that were suspicious of laxity. This same procedure was followed after a second injection. To make an accurate evaluation before and after the treatment, the use of NSAID, physical therapy or exercise therapy was prohibited. RESULTS: The mean pain duration of the subjects was 5.48+/-7.04 years, and the mean age of the subjects was 49.58+/-16.52 years. The result from VAS showed a statistically remarkable reduction after the injection (p<0.01). The VAS decreased from 7.00+/-0.17 to 4.31+/-0.21 after the first injection and this score further decreased to 2.55+/-0.19 after the second injection. There was no statistically significant relationship between the duration of pain and the effect of the treatment (p>0.05). CONCLUSION: This research demonstrated that prolotherapy is an effective method in treating patients with chronic musculoskeletal pain caused by tendon or ligament relaxation.

This study represents the radiologic, histologic features & clinical analysis of hyaline mambrane disease in 47 newborn infants who were delivered in Ewha Womans Univ. Hospital & expired caused by repiratory distress & confirmed by autopsy , during Jan. 1981 to June, 1984. The results were as follows; 1. Classification ofradiolgraphic stage (by Wolfson's criteria); Stage III(34.1%) was the most frequent. 2. Male to female ratio was 2.4:1. 3. Method of delivery; Cesarean section (44.7%) was the highest frequency, compared with percent ofcesarean section to total delivery(29.0%). 4. Distribution of birth weight; 1.0-2.0 Kg(48.9%) was the mostfrequent. 5. Distribution of gestational period; 32-36 weeks (29.8%) was the most frequent. 6. Complication; Pulmonary hemorrhage(31.9%) was the most frequent, in order, subarachnoid hemorrhage & pneumothorax were followed.7. Final diagnosis of hyaline membrane disease was based on histo-pathologic diagnosis.

OBJECTIVE: Birth weight of the newborns is the major factor affecting maternal, childhood mortality and morbidity. The purpose of this study was to identify the effects of maternal weight gain and Body Mass Index (BMI) gain by trimester of pregnancy on birth weight of newborns. METHODS: The data of 73 women who delivered at our institute from March 2004 to June 2004 were analyzed. Maternal weight gain and BMI gain during pregnancy was calculated. Statistical analysis was done. RESULTS: The standardized woman in 1.6 m height had total 12.5 kg weight gain during pregnancy. The BMI was calculated. Women with total BMI gain over 4.88 were grouped in over BMI group. The BMI gain by trimester and gestational age of pregnancy were analyzed. Maternal BMI gain in the 3rd trimester of pregnancy influences more strongly newborns' weight than does in the 1st or 2nd trimester. CONCLUSION: We considered that maternal BMI gain during each trimester of pregnancy was a marker of newborns' weight gain.

N,N-Diethylnitrosamine (DEN) has been proved to have carcinogenic potential in the initiation or promotion stage and the transformed cells proliferate to form preneoplastic nodules which are positive for placental form of glutathione S-transferase (GST-P). E-Cadherin, a member of the cadherin family, is expressed in epithelial cells. To evaluate the role of adhesion molecules (E-Cadherin, alpha-catenin, and beta-catenin), which have not been well understood in carcinogenesis, we investigated the changes of E-cadherin, alpha-Catenin and beta-Catenins by immunohistochemistry and immunoblotting in DEN-induced hepatocarcinogenesis of rat liver. In addition, the sequential analysis of histopathology and the expression of GST-P were also examined. Immunoreactive areas for GST-P were gradually increased from early period of carcinogenesis and strong GST-P positive foci were noted in various lesions, especially in the clear cell and eosinophilic cell nodules. Immunohistochemically, the E-Cadherin expression was increased in DEN-treated preneoplastic nodules in 4 and 10 weeks and hepatocellular carcinomas displayed relatively reduced expression compared with the hyperplastic nodules. But alpha- and beta-catenin expression was increased in hyperplastic nodules and hepatocellular carcinomas. Immunoblotting studies revealed that the level of alpha-catenin (cytosol and membranous fraction) was overexpressed in hyperplastic nodules as well as hepatocellular carcinomas, which showed markedly increased expression. The membranous fraction of beta-catenin was markedly increased in 10 weeks of DEN treatment and slightly reduced in hepatocellular carcinomas. These findings suggest that during DEN-induced hepatocarcinogenesis, the clear cell and eosinophilic cell nodules expressing GST-P in their cytoplasm are early transformed cell nodules. The altered expression of E-Cadherin and catenins is closely related with tumor propagation. Loss or reduced expression of E-cadherin may play a role in the progression of late hyperplastic nodule to hepatocellular carcinoma in DEN-induced rat hepato carcinogenesis.

Mucin-hypersecreting biliary neoplasm excretes excessive mucin that fills the biliary tree and results in marked dilatation of the bile ducts and obstructive jaundice. In these neoplasm, the mucin produced by the tumor rather than the tumor itself plays an important role in clinical course and radiologic patterns. The purpose of this paper is to report characteristic radiologic patterns of mucin-hypersecreting biliary neoplasms in two cases. These neoplasms were characterized by not only multilocular cystic hepatic mass or extra-hepatic bile duct mass resulting in marked biliary dilatation distal to the mass on US or CT, but also change of shape and extent of amorphous filling defects in the markedly dilated bile duct on serial cholangiograms.
