OBJECTIVE: The objective of this survey is to introduce the recent adolescent sexuality, such as the level of sexual knowledge of adolescent, their actual state for the attitudes and behaviors toward sex, and in Korea in comparison with the past and to seek the answers to the improvement of the teproductive health statos of the adolescents. METHOD: The total number of 11,433 girls was drawn fiom middle and high schools girls in Seoul, Pusan, Incheon, Kwangju, Taegu, Taejeon and Ansan. Among them, the number of 82 girls was drawn fiom factory workers in Ansan. For the data collection, the survey was conducted during the period fiom Feb 15, 1994 to May 23, 1995 by using prepared questionaire. RESULT: Of those who respond to this study, 37.6% had sexual problems, which was that of acquaintance of the opposite sex(44.7%), menstruation(33.1%), and sexual maturity(13.1%). Among them, only 5.5% had a feeling of satisfaction about sex education. In regard to the attitude toward the friendly relationsbip with the oppasite sex, the approval rate respondents was 80.4%. Many respondents felt chastity and a virtue, but only 60.1% answered that pemarital chastity should be kept. For the each age group, age at sexual intercourse is revealed that among the respondents about 31.5% are experienced sexual intercourse for under 14 yearss old group, 25.3% for 15 years old, 26.3% for 16 years old, 12.6% for 17 years old, 3.3% for 18 years old, 1.0% for 19 years old. The major information source of knowledge source was school(38.4%), mass-media such as TV/radio(22.6%), book and magazine(19.9%), friends(16.2%), and parents (1.5%). CONCLUSION: In order to cope with the problems of adolescent sexuality, a drastic and strong policy measures should be taken by the government. At the same time, the public should be aware of the urgency of adolescent sexual problems. The most effective countermeasures appear to be education. Sexual education is necessary for the youth that they should bave an adequate sexual knowledge, attitudes and behaviors in their adolescent period.

Carcinoma of the uterine cervix is the most common malignant tumor in Korean women. It is well known that carcinogenesis is a multi-step event involoving the inactivation of tumor supressor genes, such as p53 gene and RB gene. The inactivation of the normal functions of the tumor-suppressor proteins pRB and p53 are important steps in human cervical carcinogenesis, either by mutation or from complex formation with the HPV E6 and E7 oncoproteins. The pRB protein regulates early cell cyle progression by controlling transit through the G1 phase of the cell cyle. The p53 tumor suppressor gene product also plays a role in cell cycle control by the transcriptional regulation of cyclin-CDK inhibitor. Cervical carcinoma is an excellent model for studying the stepwise progression of cell transformation because this is reflected morphologically by the increasing dysplasia of the squamous cells before it becomes and invasive squamous cell carcinoma. The aim of this study was to examine the expression of pRB and compared that with overexpression of p53 in a series of cervical lesions including normal tissuess, dysplasias, carcinoma in situ and carcinomas by immunohistochemical staining with monoclonal antibody to elucidate the role of these tumor suppressor genes. The result were as follows: 1. In normal cervical mucosa and CIN I , a few positively stained cells for pRB were seen in basal and parabasal layer. 2. An abnormality of pRB, loss of expression was seen in 23.8% of CIN III and in 10.8% of invasive carcinoma. 3. Overexpression of p53 was demonstrated in 14.3% of CIN III and in 59.5% of invasive carcinoma. 4. The immunoreactivity of p53 was significantly increased (p<0.05) in stage II, III than stage I , whereas downregulation of pRB and tumor stage was not correlated. 5. The immunoreactivity of p53 was significantly increased (p<0.05) in squamous cell carcinoma than in adenocarcinoma, adenosquamous carcinoma and CIN III. These result suggest that an alteration of pRB is more frequently implicated in CIN III than invasive carcinoma, whereas overexpression of p53 may be involevd in late progression of uterine cervical carcinoma.

Benzoyl peroxide has been known to have bacteriostatic activity against Corynebacterium acnes and to have comedolytic action in patients with acne vulgaris. The present study was undertaken to evaluate the therapeutic effect of Renoxal, a 5% benzoyl peroxide lotion, in patients with acne vulgaris. A total of 35 patients entered this study at the Department of Dermatology, Seoul National University Hospital during the five months period from March to July, 1978. All patients were instructed to apply Benoxal on their affected sites once or twice daily; and the number of lesions on three fixed areas were counted before and every week for four weeks after the treatrnent. Two female patients stopped the application due to developrnent of contact dermatitis to Benoxal The results observed in the 33 patients were as follows: 1. The percentage decrease in total number of lesions in four weeks after treatment was 51.1% 2. Closed and open comedones were gradually eliminated; and their numbers were decreased in four weeks after treatment by 45. 8% and 55. 3% respectively. The papules were decreased. by 59. 1 @2 after the first week of treatment, but showed. a transient lag around tbe second week and then marked 61. 5% in four weeks after treatment. 3. Observed side effects included burning sensation,(3 cases), tightness (3 cases), itching sensation (2 cases) and scaling (1 case). All were tolerable without any specific measure or discontinuance of the application. The authors concluded througb this experiment that Benoxal (5% benzoyl peroxide lotion) is a very effective local therapeutic agent in the treatment of acne vulgaris patients.

Primary papillary serous carcinomas (PPC) of the peritoneum are very rare and classically present with widespread intraperitoneal dissemination, superficial invasion, and minimal ovarian stromal involvement. Because of clinically and histologically similar to advanced stage epithelial ovarian carcinoma the treatment has been a similar fashion-cytoreductive surgery followed by systemic chemotherapy. Histologic differentiation between papillary mesotheliomas, primary ovarian tumors, borderline tumors of the ovary with peritoneal deposits and primary peritoneal carcinoma may be difficult. The prognosis is very poor and the median lifespan 4 months. We experienced a case of primary peritoneal carcinoma and reported with the brief review of the literature.

PURPOSE: To investigate the difference in donor corneal cell changes after penetrating keratoplasty in various corneal diseases. METHODS: Subjects included 36 eyes from 35 people with at least 6 months of follow-up who had undergone penetrating keratoplasty between August 2000 and December 2002. The patients were classified into three groups based on the state of the corneal endothelium. Changes in cell density, polymorphisms, and polymegathism of the donor cornea were compared between groups. Results were analyzed by ANOVA. RESULTS: The overall corneal endothelial cell density after grafting was lower, but the differences in endothelial cell states between the recipient cases were not statistically significant. The change in corneal endothelial cell density showed a significantly higher difference (p=0.0013) when patients had either undergone a rejection episode during recovery or recurred herpetic uveitis. CONCLUSIONS: The preoperative state of the corneal endothelium may affect the survival of donor corneal endothelium after grafting. However, rejection of the transplant contributes more significantly to the survival of the donor corneal endothelium than other factors. We suggest close observation and keen therapy with respect to rejection after grafting.
