In order to evaluate the effect of zinc sulfate on acne vulgaris, this study was performed during 3 months' period from October, 1979 to December 31, 1979. Total number of acne patients visited at the Department of Dermatology, Han Gang Sung Shim Hospital were 130, but among them 58 patients had completed this atudy. The patients were classified in 3 groups, A, B, C, as follows. Group A (23 patients) who were treated with zinc sulfate (600mg/day) and 2. 5% benzoyl peroxide Group B (20 patients) who were treated with tetracycline (initial: 750mg/day, after 2weeks: 500rng/day) and 2. 5% benzoyl peroxide. Group C (15 patients) who were treated with only 2. 5% benzoyl peroxide. To evaluate the efficacy of treatment in these 3 groups, the number of open comedone, closed comedone, papule and pustule were counted every other week for 8 weeks. (countiuned..)

We report two cases of hyperlipoproteinernia(HLP) with various cutaneous xanthomas. Case 1 was a 12-year-old girl, who had tuberous, tendinous, and plane cutaneous xanthomas and corneal arcus of the left eye. Case 2 was a 40-year-old man, who had tuberous, eruptive, and plane cutaneous xanthomas. Serum lipid and lipoprotein analysis reveoled patterns of Type IIa HLP in case 1 and, of Type IIb HLP, in case 2. They have been treated with diet control and hypolipidemic drugs and are under our continuing medical supervision.

PURPOSE: To evaluate the treatment results and prognostic factors after radiotherapy in stage IIB uterine cervix cancer. MATERIALS AND METHODS: We retrospectively analyzed the records of 90 patients with stage IIB uterine cervix cancer who received radiotherapy between 9/94 and 12/99. Age was ranged from 28 to 79 years (median 57). Tumor size was > or = 4 cm in 64 patients. Preteatment SCC level was measured in 76 patients. Twenty nine patients received conventional radiotherapy (QD) and the others received modified hyperfractionated radiotherapy (BID). Only 7 patients in BID had tumor size <4 cm. All patients received high dose rate brachytherapy (4 Gy x 7 or 5 Gy x 6). No patient received concurrent chemotherapy during radiotherapy. Follow up period was ranging from 9 to 76 months (median 38). RESULTS: The 5-year overall and disease free survival rates were 73.4% and 71.6%, respectively. Local recurrences occurred in 10% of patients, and distant metastasis in 18.9%. There was a significant correlation between OS/DFS and tumor size (<4 cm; OS 95.2%, DFS 91.4%, > or = 4 cm; OS 63.4%, DFS 63.4%). Pretreatment SCC level was one of prognostic factors only in univariate analysis. CONCLUSION: With modified hyperfractionated radiotherapy, there was very low local recurrence rate (6.6%) and high 5-year overall and disease free survival rate (75.4% and 70.5%), which is comparable to results after concurrent chemoradiotherapy in bulky, locally advanced stage IIB uterine cervix cancer.

BACKGROUND: Angiogenesis is crucial for many biological processes such as embryogenesis, cyclic changes in the endometrium and wound healing. It is also critical for the growth, invasion and metastasis of solid tumors. Vascular endothelial growth factor (VEGF) acts as a mitogen for endothelial cells and is expressed by the presence of various tumor cells. The objective of this study is to evaluate if angiogenesis is involved in the mouse skin carcinogenesis and if VEGF is related to angiogenesis. METHODS: We induced premalignant and malignant lesions on mouse (BALB/c) skin using the two stage chemical carcinogenesis moedl, DMBA (7,12-dimethylbenzanthracene) initiation and TPA (tetra decanoyl-phorbol-acetate) promotion. And we analysed the microvessel densities (MVD) and expression of VEGF in various stages of premalignant and malignant lesions by immunohistochemical studies. RESULTS: Squamous papillomas, keratoacanthoma, dermatofibroma, and squamous cell carcinomas were developed in 20 weeks. There were no differences in the incidence of benign and malignant tumors between 10-week and 20-week promotion groups. There were significant increases in MVD from normal and hyperplastic skin through premalignant lesion to invasive squamous cell carcinoma (p<0.0005). But the degree of VEGF expression neither correlated with neither MVD nor the tumor groups. CONCLUSIONS: Increased angiogenesis begins from the hyperplastic stage. VEGF produced by tumor cells may not play major roles in the angiogenesis in the two stage chemical carcinogenesis model of the mouse skin.

In the case of a soft tissue defect which requires thin & pliable tissues, the choice of donor site is limited due to flap bulkiness and donor site morbidity. To overcome these problems, a variety of perforator-based flaps such as paraspinous and parasacral perforator flap, deep inferior epigastric perforator flap, gluteal perforator flap, and thoracodorsal artery perforator flap have recently been introduced. We experienced 8 cases of soft tissue defects from December 1996 to March 1999 using the thoracodorsal artery perforator flap for reconstruction. We could elevate the cutaneous flap with preservation of the latissimus dorsi muscle flap only when it was based on one cutaneous perforator. Defatting procedure was possible for further thinning of skin flap. In one case, axillary defect after release of postburn scar contracture was repaired with island perforator flap and the other seven cases were repaired with free flap. The results were satisfactory. We believe the thoracodorsal artery perforator flap is useful for reconstruction of soft tissue defects which are large or under conditions requiring thin flap.

Localized fibrous tumor is an uncommon submesothelial origin tumor found in pleura most commonly. Sixty five-year-old man with right lower quadrant pain was admitted. He was treated with resection of tumor and was diagnosed as localized fibrous tumor of pelvic cavity. He is now being followed up without any evidence of recurrence for 34 months. This case is presented with reviewing references.

It is commonly believed that the branchial anomalies are persistent remnants of the embryologic branchial apparatus. These anomalies are originated from branchial cleft and most commonly involved in second branchial deft. Clinically they present palpable mass, discharge from fistula, recurrent infection due to obstruction of Gstula tract. As respiratory symptoms, they may present hoarseness, preceeded by or associated with upper respiratory infection. However, it has not been reported that they caused airway obstruction in newborn infants. Wc experienced a case of the fourth branchial deft cyst in a 2 day old infant who showed respiratory difficulty due to airway obstruction.

OBJECTIVE: To evaluat the effects of a culture medium with glucose in the presence of glutamine on the development of mouse embryos. METHODS: Two-cell embryos recovered from ICR mice at 48 hrs after hCG injection (mated just after hCG injection) were cultured in DMEM (with 20% hFF) supplemented with or without glucose on the presence of glutamine. Embryos were cultured under three different glucose regimens: (1) 0 mM (control); (2) 0.5 mM (group I); or (3) 3.15 mM (group II), and were analyzed at 24, 48, 72 and 96 hours intervals. Chi-square test (x2-test) was used to compare values of groups. RESULTS: No differences were found in the number of embryos showing morula (control: 37.5%; group I: 51.0%; group II: 48.4%), blastocyst (control: 21.5%; group I: 33.3%; group II: 34.4%) and blastocyst and hatching or hatched blastocyst (control: 81.9%; group I: 83.3%; group II: 82.8%) between groups at 24 hrs, 48 hrs or 72 hrs respectively. However at 96 hrs, the number of hatched and attached blastocyst was significantly higher in group I (82.3%) and II (78.5%) than control (63.2%; P<0.05). CONCLUSION: The addition of glucose (0.5 mM) to the DMEM, as energy source, improved the rate of development of late stage embryos in mice.

OBJECTIVE : Mammalian embryos undergo changes of energy environment for transfer from oviduct to uterus. Also, the human reproductive organ (oviduct, uterus) contains energy sources of different concentration (oviduct - glucose: 0.5 mM, pyruvate: 0.32mM, lactate: 10.5 mM; uterus - goucose: 3.15 mM, pyruvate: 0.1mM, lactate: 5.87 mM, respectively). This study was conducted to examine the effect of these energy sources added in DMEM with glutamine on the mouse embryo development. METHODS: There was used ICR female mouse. Two cell embryos of mouse are collected by method of 'flushing'. Flushing fluid was used Ham's F-10 added to 20% FBS. The collected 2 cell embryos were cultured in media such as Control (only DMEM), group A and B (DMEM supplemented with 0.5 mM and 3.15 mM glucose), and group C and D (DMEM supplemented with 0.1 mM and 0.32 mM pyruvate), and group E and F (DMEM supplemented with 5.87 mM and 10.5 mM lactate). All experimental media supplemented with 20% hFF, respectively. Pattern of embryo development was observed to interval at 24hr during 96hr. RESULTS : The media with glutamine added glucose (group A: 51.0%; group B: 48.4%) was significantly (p<0.05) higher than other experimental group in development into the morula stage after 24 hr in culture, but not significantly different compared with control and the rate of development into the blastocyst was significantly (p<0.05) low in the both of pyruvate (group C: 7.9% group D: 6.8%) and lactate (group E: 7.1%, group F: 7.1%) treatment group after 48 hr in culture. Development into the hatched and attached balstocyst after 96hr in culture revealed similarly in control (81.9%) and glucose treatment group (group A: 83.3%, group B: 82.8%). However, development into the hatched and attached blastocyst after 96hr in culture revealed significantly (p<0.05) development in the glucose treatment group (group A: 82.3%, group B: 78.5%) than control (63.2%), and its of pyruvate (group C: 34.1%, group D: 34.1%) and lactate (group E: 25.9%, group F: 33.3%) treatment group were significantly (p<0.05) lower than control similar to previous observations. CONCLUSION : The glucose added to the DMEM with only glutamine, as energy source, was highly to the rate of development compared with control, but the other energy sources were not, synthetically. Above refer to, the human reproductive organ (oviduct, uterus) contains energy sources of different concentration. Thus, further studies are will examine continuously to effects by interaction of different energy sources in the mouse embryo culture.
