To investigate the immunohistochemical expression of mutated p53 protein and bcl-2 protein in the cutaneous melanocytic lesion, 15 cases of compound nevus, 10 cases of congenital melanocytic nevus, 15 cases of primary malignant melanoma(4 cases less than 1.5 mm thick and 11 cases more than 1.5 mm thick), and 10 cases of metastatic malignant melanoma(7 cases in lymph node and 3 cases in soft tissue) were examined. All cases of compound nevi and of congenital melanocytic nevi showed no immunoreactivity for p53 protein. p53 protein overexpression was observed in 75%(3/4) wth primary malignant melanoma less than 1.5 mm thick, 81%(9/11) with primary malignant melanoma more than 1.5 mm thick, and 100%(10/10) with metastatic malignant melanoma. The difference in p53 protein overexpression was statistically significant between benign nevi and malignant melanoma(p<0.01). Bcl-2 protein expression was observed in 73%(11/15) with compound nevus, 70%(7/10) with congenital melanocytic nevus, 75% (3/4) in primary malignant melanoma less than 1.5 mm thick, 54%(6/11) with primary malignant melanoma more than 1.5 mm thick, and 40%(4/10) with metastatic malignant melanoma. These findings suggested that mutation of p53 gene may be an important mechanism in the development of malignant melanoma. Although bcl-2 protein was expressed in cutaneous melanocytic lesion, no correlation was found between p53 protein and bcl-2 protein expression in malignant melanoma.

OBJECTIVES: To evaluate the relation of onset-age and plasma level of beta-endorphin, Ethanol, beta-endorphin, cortisol and blood glucose were compared in 48 male alcoholics and 29 normal controls. METHODS: Alcoholics are divided into two groups by onset-age of alcoholism. Blood samples were obtained before and after 0.75gm/kg of ethanol consumption at the 7th admission day. RESULTS: 1) The ratio of onset-age before 25 years to after 25 years of the patients group was 2 to 3. 2) There was no significant difference in age at admission between two patient groups. 3) There was no significant difference in change of plasma ethanol levels among three groups. 4) There was no significant difference in change of plasma beta-endorphin levels among three groups. 5) There was no significant difference in change of plasma cortisol levels among three groups. 6) There was no significant difference in change of fasting blood sugar levels among two patient groups.

Authors report a case of separation anxiety disorder, which developed as a side effect during haloperidol treatment of Tourette syndromes(TS). In this case, 14 years old boys developed attention deficit symptoms during his infancy. At 4th grade of primary school, he developed vocal tic, motor tic, and coprolalia. With 5mg/day of haloperidol treatment his symptoms of TS were subsided. During the treatment, he developed features of separation anxiety disorder, including dependence, pleading, clinging, and sadness. Symptoms of attention deficit and separation anxiety disorder were improved by 25mg/day of imipramine treatment. During haloperidol treatment of TS, careful observation may be needed whether separation anxiety disorder-like symptom develops.

PURPOSE: We evaluated a rapid preparation procedures for the labeling and quality control of 99mTc-ECD, MAG3, and MIBI using microwave heating and Sep-Pak cartridges. MATERIALS AND METHODS: 99mTc labeling of ECD, MAG3, and MIBI kit preparation was performed according to the package inserts with microwave heating modification. Heating time was 10-15 sec, and heating was performed with 3 mm plastic bottle with screw cap to prevent radiation contamination. Labeling efficiency was obtained with C18 or Alumina N Sep-Pak cartridges. RESULTS: The radiochemical purity of 93~96% for 99mTc-ECD and 95~99% for 99mTc-MIBI was obtained using Alumina N Sep-Pak cartridge. The optimum irradiation time of microwave method for 3 ml 99mTc-labeled radiopharmaceutical solution was 10 sec for 99mTc-ECD and 99mTc-MIBI, and 15 sec for 99mTc-MAG3. The RESULTS of quality control data with Sep-Pak cartridges were well correlated with TLC method. The total preparation time of these radiopharmcaeuticals was 5~6 min including quality control procedure. CONCLUSION: This study demonstrates that radiopharmaceuticals preparation by microwave heating and quality control by Sep-Pak cartridges can be efficiently utilized as an alternative to the recommended method by manufacturer's manual.

To evaluate the detection of HPV DNA according to subtype of lesions of uterine cervix and its clinical applicability, in situ hybridization (ISH) and immunohistochemistry for HPV were performed in 189 cases of uterine cervical lesion, including 23 cases of low grade squamous intraepithelial lesion (SIL), 115 cases of high grade SIL and 51 cases of invasive carcinoma. Positive immunostaining, brown precipitate, was mainly noted in the nucleus of koilocytes in the superficial and intermediate layer. Positivity of immunostaining was 21.7% in low grade SIL, 13.0% in high grade SIL and 9.8% in invasive carcinoma. Positive reaction in ISH, red precipitate, was noted in the nucleus of not only koilocytes but also non-koilocytes in the superficial and intermediate layer, and dot precipitate was rarely identified in the nest of squamous cell carcinoma. Based on HPV subtype, 6/11 was 21.7% in low grade SIL, 16/18 was 32.2% and 39.2% in high grade SIL and invasive carcinoma, respectively. With regard to their associated HPV types, low grade SILs were heterogeneous and high grade SILs and invasive carcinomas were related with the high oncogenic risk group only. The correlation of HPV subtypes with panHPV was 91.3% in low grade SIL, 91.3% in high grade SIL and 98.0% in invasive carcinoma. These results suggest that detection of HPV infection by ISH may be a more useful method than immunohistochemistry and application of the HPV subtype probe with the panHPV probe could improve the sensitivity of ISH.

Adenosquamous carcinoma of stomach is a mixed glandular-epidermoid tumor where both components are neoplastic. Its incidence is extremely rare. The five theories on the origin of squamous components are 1) island of ectopic squamous epithelium in the gastric mucosa, 2) squamous metaplasia of gastric epithelium, 3) squamous differentiation in a preexisting adenocarcinoma, 4) endothelial cell differentiated toward squamous elements, and 5) totipotential undifferentiated cells of the gastric mucosa. We experienced three cases of adenosquamous carcinoma. Case 1 was a 71-year-old female patient; an ulcerative lesion was present in the pylorus, measuring 5 cm in diameter. Case 2 was a 57-year-old male patient; an ulcerative lesion is present in the pylorus, measuring 6 cm in diameter. Case 3 was a 58-year-old female patient; an ulcerative lesion was present in the body and fundus, measuring 10 cm in diameter. Microscopic examination revealed a mixed malignant squamous and adenomatous component.
