To evaluate the morphologic changes of the renal arteries in the condition of high-salt diet, we scheduled the control group which fed routine animal diet added 0.06% of Sodium chloride, low-salt group which fed with 2.0% of sodium chloride, and high-Salt group which fed with 8.0% of sodium chloride. The experimental animals were sacrificed every two weed until 20 weeks of final experimental week. The results obtained were as follow; 1. Slight intimal thickening of the renal arteries is observed from 16th experimental week and continued the end of the experiment in the rats of control group. 2. In low-salt group slight intimal thickening of the renal arteries is observed from 12th experimental week and continued to the end of the experiment. 3. In high-salt group the intimal thickening began from 6th experimental week and its degree was hasten with week, and provoked moderate to high degree of lesion at the end of the experiment. Medial proliferation and degeneration of the intima and media, though their quality is mild, also associated at the end of the experiment.

Incarceration of the gravid uterus is a rare but serious complication of pregnancy. Reported is the case of a gravid 2, para 0, abortus 1 with known uterine subserosal myoma(5.3 x5.5cm sized) 26-year-old woman presented with acute dysuria and urinary retention. The patient was 14 weeks and 3 days pregnant and presented several week history of urinary frequency and sensation of incomplete bladder emptying. Examination revealed a retroflexed uterus with cervical opening pointing toward the anterior abdominal wall. An ultrasound revealed a thin, elongated maternal bladder and a uterus incarcerated between the sacral promontary and the pubis. The incarceration was successfully reduced by tenaculum traction of the cervical posterior lip without surgical intervention and had a normal infant of appropriate weight at term.

An 18-year-old man had suffered from intense burning with redness and an increased temperature of both the lower legs, forearms and hands since the age of 5. Symptoms were exacerbated by exposure to heat or walking. The patient obtained temporary relief by immersing his feet and hands in cold water. We observed the increase of skin temperature in relation to pain by thermography. No specific abnormalities were noted in laboratory studies. Treatment with aspirin was ineffective. We report a rare case of primary erythermalgia with typical features.

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.

Hepatic fibrosis was induced in Sprague-Dawley rate to evaluate the ultrastructural changes of fat-storing cells (Ito cells). For experimental induction of liver fibrosis, the rats were administered intraperitoneally with 0.5 ml of 50% Ccl4 solution per Kg body weight, twice weekly for 12 weeks. The rats were sacrificed every week. The liver tissues were examined under light and electron microscopes. And the immunohistochemical study of desmin was also performed. The results were summarized as follows: Light microscopic findings: The cellular infiltrations was inflammatory cells and Kupffer cells developed from 1 week after Ccl4 injection, and were the most severe in 4 weeks. The strong immunoreactivity for desmin was also evident in 4 weeks. The centrilobular necrosis and fibrosis developed from 2 weeks after injection, and the necrosis persisted until 8 weeks. The progress of fibrosis was accompanied by decreases in cellular infiltration and reactivity for desmin, and increased gradual nodular formation was also observed. The cirrhosis was developed after 10 weeks. Electron microscopic findings: An increase in number of fat-storing cells was observed from 1 week after injection. Transitional cells characterized by a depletion of lipid droplets and a hypertrophy of the rER appeared after 2 weeks. The number of transitional cells with abundant collagen fibers in the extracellular spaces increased in 4 weeks. With progression of fibrosis the number of fat-strong cells decreased and proliferating fibroblasts with dilated rER were observed. According to these results it was revealed that there was an apparent transition from fatstrong cells to transitional cells and to fibroblasts. These cells had a few similar characteristics and may belong to the same cell population. Thus it was suggested that fatstrong cells might play an important role in hepatic fibrosis.

The authors developed a comfortable program for routine work of surgical pathology. We used IBM PC (80386) and Foxbase plus program. The main function of this program was automatic coding and concurrent surgical report printing. During gross printing, previous biopsy number and its diagnosis were automatically searched and printed below gross description. The reported data were stored during surgical report printing simultaneously, and thus the typist's workload became considerably reduced. Search for specific cases could be performed by patient's name, surgical number, hospital number, diagnostic code numbers (SNOMED code micro glossary), and certain disease entities on very short duration.

Sclerosing hemangioma of the lung is uncommon benign neoplasm of uncertain histogenesis. Their radiologic appearance is relatively distinct and well defined. Recently we experienced 3 cases of sclerosing hemangioma of the lung in 54, 52, 51 years old women. The light microscopic findings are similar to the features reported by Liebow and Hubbell (1956).

The clinical and pathological features of a case Malignant mixed mullerian tumor of the ovary in 45 year-old female patient with a brief review of the literature are presented. She had both ovarian tumors. The masses are multilocular cystic tumor with interspersed solid component. The cystic component is filled with serous fluid. Microscopically the tumor is composed of epithelial element & intimately related mesenchymal element. The epithelial element shows the findings of adenocarcinoma of solid, glandular and papillary growth. The mesenchymal element is composed of malignant-looking stroma with cartilage formation.
