Ota's nevus is a mongolian spot-like macular blue-black or gray-brown patchy pigmentation that most commonly occurs unilaterally in areas innervated by the first and second division of the trigeminal nerve. We report a case of Ota's nevus treated by combination therapy with cryosurgery and a Q-switched Alexandrite laser. A 48-year-old female had had a type III Ota's nevus from birth. Cryosurgery was tried at first using hard chalk dry ice on the lesion of the forehead and cheek. After that, The Q-switched Alexandrite laser was used three times at twelve week intervals at the site of the eyelid. Good therapeutic effects were gained and our patient was very satisfied. There were no complications or scarring. A Biopsy of the area treated revealed a similar histological pattern with significantly less melanin indicating melanin removal. Combination therapy with cryosurgery and an Alexandrite laser on the Ota's nevus may be cheaper, more effective and a safer method. It may also reduce the limitation of the two methods when used individually.

OBJECTIVE: The objective of this study is to evaluate the expressions, microvessel counts and angiogenic pathway of VEGF and PD-ECGF and proliferative activity of Ki-67 according to clinicopathologic feature of cervical tumor. METHODS: Two hundred three cervical specimens were evaluated; among these 20 were designated normal epithelium, 36 mild dysplasia, 28 moderate dysplasia, 36 severe dysplasia, 28 carcinoma in situ, 17 microinvasive carcinoma and 38 invasive cervical carcinoma (21 squamous cell carcinoma and 17 adenocarcinoma). Microvessel count was determined by immunohistochemical staining using anti-factor VIII-related monoclonal antibody. The expression of VEGF (vascular endothelial growth factor) and PD-ECGF (platelet-derived endothelial cell growth factor) were evaluated by immunohistochemical staining with anti-human VEGF monoclonal antibody and anti-dThdPase monoclonal antibody. The proliferative activity was examined using a Ki-67 equivalent monoclonal antibody (MIBl). RESULT: There was no statistical significance on microvessel count except invasive cancer comparing with mild dysplasia including normal tissue, but there was a little increase in microvessel counts according to severity of tumor. The intensity of VEGF and PD-ECGF expression was significantly correlated with severity of cervical tumor. And the microvessel density was significantly higher in the positive expression of VEGF and PD-ECGF than in the negative expression. The intensity of PD-ECGF expression in invasive adenocarcinoma was significantly lower in comparison with VEGF expression. The intensity of Ki-67 expression had no correlation with severity of cervical tumor and was significantly higher in moderate and severe dysplasia than in microinvasive and invasive carcinoma. Ki-67 expression had no statistical correlation with VEGF and PD-ECGF. CONCLUSION: The VEGF and PD-ECGF are important angiogenic factors and associated with progression of cervical tumor. The VEGF may be involved in the progressions of squamous cell carcinoma and adenocarcinoma, but the PD-ECGF may not be involved or be minimally involved in the progression of adenocareinoma. There seems to be a different angiogenic pathway pertaining to the histologic difference of cervical cancer. There was no difference of Ki-67 expression according to severity of cervical tumor.

To examine the electrophysiological properties of luteal cells and the relationship between membrane potential and luteal steroidogenic capacity, the membrane potential of luteal cells and the luteal steroidogenesis were measured under different ionic conditions following treatment with various drugs and gonadotropins. The membrane potential of luteal cells did not vary throughout the estrous cycle and was -55 +/- 1 mV. The membrane potential was highly dependent upon the external K+ concentration and was depolarized by the deprivation of external Ca2+, however) there seemed to be a lower K+ permeability in luteal membranes as the presence of 10-9 M valinomycin, a K+ ionophore Caused hyperpolarization from -55 to -91 mV. Luteal progestin production was increased in a high K+ solution but not m a Ca2+-free solution indicating that Ca2+ may be essential for steroid synthesis and/or secretion by luteal cells. Gonadotropins and ouabain induced a depolarization of the membrane potential and stimulated luteal steroidogenesis; however; prostaglandin F2alpha stimulated only steroidogenesis without any changes in membrane potential. These results suggest that the relationship between steroidogenesis and the changes in membrane potential by drugs and gonadotropins is still obscure and remains to be eluridated. The relationship between membrane potential and steroidogenesis in the luteal cell may be dependent upon the availability of intracelluar Ca2+.

OBJECTIVES: We studied peritoneal fluid and serum LDH levels to identify patients with ovarian carcinoma and differentiate them from patients with benign ovarian tumor or other gynecological tumors. METHODS: From July 1998 to May 1999, peritoneal fluid and serum LDH, serum CA-125 levels were measured in 95 patients: 11 with ovarian carcinoma, 2 with borderline ovarian tumor, 45 with benign ovarian tumor, 2 with endometrial carcinoma, 21 with CIS, 7 with cervical cancer and 7 with uterine myoma. RESULTS: Peritoneal fluid LDH and serum LDH and CA-125 levels in ovarian cancer patients were significantly higher than those in patients with benign ovarian tumor and other gynecological tumors(p<0.05). Peritoneal fluid LDH demonstrated higher sensitivity(100%) and greater diagnostic efficiency(86%) than serum LDH(73% and 84%, respectively) or serum CA-125.(82% and 83%, respectively) CONCLUSION: Peritoneal fluid LDH, compared to serum LDH and serum CA-125, presented the greatest diagnostic efficiency in discriminating ovarian cancer from benign ovarian tumor and, therefore, it may be efficient as a biochemical marker in diagnosis of ovarian cancer, even in early stages of the disease.

Vesiculobullous eruptions are a rare cutaneous manifestation of systemic lupus erythematosus (SLE). They are related to intense inflammation within the cutaneous lesions and subsequent blister formation. We report a case of vesiculobullous eruption of SLE in a 23-year-old male. The bullous eruptions were present ori the lip, forehead, both feet and hands. He met ARA(American Rheumatism Association) is criteria for a diagnosis of SLE and the eruptions developed during a systemic attack of the disease. Routine histology of the lesion showed subepidermal blisters with intact epidermis and dense neutrophilic infiltration in the upper dermis. Direct immunofluorescence of lesional skin showed a linear-granular pattern of immune deposits at the dermoepidermal junction. Electronmicroscopy of the lesional skin showing subepidermal bullae are located beneath the lamina densa. Combination therapy of prednisolone and hydrochloroquine showed complete clearing of the lesions within several weeks. We observed a good response without evidence of recurrence.

OBJECTIVE: To evaluate the clinicopathologic features and clinical outcomes of adnexal tumors in pregnancy. METHODS: After review of charts of 51 patients managed at Kyungpook National University Hospital from January 1996 to June 2002, data including clinical findings, treatments and outcomes were analyzed. RESULTS: The mean age of pregnant women with adnexal tumors was 28.5 years old and the adnexal tumors were more common in nulliparous pregnant women (74.5%) than parous those. There were asymptomatic or no signs in 40 cases (78.4%), lower abdominal pain in 9 cases (17.6%), vaginal bleeding in 1 case (2.0%) and palpable mass by patient herself in 1 case (2.0%). The surgical treatments were performed at first trimester in 9 cases (19.1%), second trimester in 31 cases (66.0%) and third trimester in 7 cases (14.9%). Postoperative histopathologic diagnoses of adnexal tumors were 22 cases (43.1%) of benign cystic teratoma, 7 cases (13.8%) of functional cyst, 6 cases (11.8%) of serous cystadenoma, 4 cases (7.8%) of mucinous cystadenoma, 4 cases (7.8%) of endometrioma, 3 cases (5.9%) of parovarian cyst and 4 cases (7.8%) of malignancy including 2 cases of mucinous cystadenocarcinoma and 2 cases of mucinous tumor, borderline. The complication resulting from adnexal tumors was torsion of 6 cases (11.8%). The outcome of pregnancy was available in 30 cases, term delivery in 25 cases (83.3%), preterm delivery in 3 cases (10%) and spontaneous abortion in 2 cases (6.7%). CONCLUSION: Although the incidence of adnexal tumors with pregnancy is variable according to the reports, the detection rate is more and more increasing due to a widespread application of ultrasound. Thus, obstetricians must always consider adnexal tumors combined with pregnancy and try to minimize the complications of surgery during pregnancy to prevent adverse fetal outcome and maternal morbidity.

This study was attempted to observe the possible effects of open chest and the decubitus position on blood gas values during controlled ventilation. We used a volume-type ventilator to maintain regular tidal volume throughout the operation. A total of 51 cases which underwent open chest surgery between 1979 and 1981 in Department of Anesthesiology in Kyungpook National University Hospital were selected. PaO2, PaCO2, pH and MAP were measured at ten minutes after induction (control group), decubitus position (ducubitus group) and chest was opened(open chest group). The PaCO2 value in open chest and decubitus group revealed a tendency of elevation compared with the control group. The PaCO2 value in open chest revealed no remarkable change compared with the control group. The pH in open chest and decubitus group showed a tendency to increase compared with the control group. The MAP showed a tendency to decrease in open chest & decubitus groups and decreased gradually. From the above results, MAP showed a gradual decrease but the increase of pH and PaO2 suggested the inclination of respiratory alkalosis due to hyperventilation during volume controlled ventilation anesthesia.
