Idod (Immediate Dissolved Oxygen Demand) is a value of the oxygen demand after 15 minute of inoculation by inorganic reducing salts. Industrial development and urban enlargement are bringing water pollution deeply, and industrial waste waters are the source of the inorganic reducing salts. Author investigated the IDOD value change according to the inorganic salts and gained the following results: 1. IDOD value influenced by Na2SO3 is 81.4 ppm. 2. Generally sulfur compounds are highly effecting on IDOD. 3. The nitrite salt had little influence on IDOD.

We report five cases of solitary mastocytoma. All patients were under one year of age and diagnosed as solitary mastocytoma based on clinicopathologic findings. Skin lesions were found on the right forearm, left hand, left leg, left elbow and left shoulder. They resolved themselves spontaneously resolution within 2 or 3 years.

The level of copayment increased in order to stabilize the financial condition of the health insurance on 1986. An important question regarding the policy was whether the increase in the level of copayments reduced the utilization of medical services in the poor selectively. In spite of the importance of the research question, no study has been reported. This study was designed to find out changes in nuniU rs of physician visits, to explain charac teristics influencing the difference of utilization before and after the program. Finally the interaction effect between the program and the level of income was examined for the abover question. A total of 10,421 persons from eight institutions was selected as the study sample. Research findings are as follows. 1. The number of physician visits decreased by ten percent as a result of increasing the level of copayment. 2. The decrease was remarkable in some groups such as children, rural area and large family. 3. The most important factor which explained the difference was the number of physician visits before the introduction of the new program.. The more numbers of physian visits during the last year were, the more numbers of physian visits decreased after the program. 4. The interaction term between the program and the level of income was statistically significant in the multiple regression model which explained physician visits and its coefficient was negative. It means that an increase in copayment did not reduced the number of physician visits in the poor, selectively. 5. It can be concluded that imposing adequate copayment reduces the use of medical services as well as medical costs without serious damage in access especially for the poor pule.

We report one case of bilateral testicular torsion. A 400 gm male infant, born by cesarean section due to induction failure at 42 weeks gestation, was hospitalized at 9 days of age secondary to bilateral testicular mass. Physical examination revealed an healthy baby with enlarged, firm, nontender mass on both sides of the scrotum. Transillumination of the mass showed no transmission of light. Laboratory data included a normal CBC and a urinalysis. Ultrasonogrophy showed well encapsulated 0.9 x 0.9 x 1.0 cm sized and 1.5 x 1.3 x 1.3 cm sized homogenous hypoechoic solid mass in left and right testicles respectively, remainder testicular parenchyme showed normal structure. Exploration of the testes was performed at 25-days old under general anesthesia. Exploration revealed a infarction of the right testes secondary to spermatic cord torsion, evidenced by clockwise turns outside the tunica vaginalis of 270 degrees. Left testes was infarcted but a quarter of them seemed normal. Orchiectomy on right and fixation on left testes were performed respectively. Left spermatic cord seemed to be detorted spontaneously. Postoperatively the infant did well and discharged 5 days after operation. Follow up examination during the next 3 months have shown appropriated sized testicle with normal colorization and arterial pulse. Testicular scan performed at age 39 days showed good perfusion of left testes.

BACKGROUND: Experience of awareness and recall during general anesthesia would be most distressing for patients. Especially for the cesarean section, medical team must consider both maternal awareness and fetal safety. Authors tried to know the possibility of propofol use as induction and maintenance agent of anesthesia for the cesarean section in respect of maternal awareness, recall and fetal safety. METHODS: Forty patients (ASA physical status 1, 2) were allocated randomly to either propofol (n=20) (P) or thiopental-enflurane (n=20) (T-E) group. We checked B.P, pulse rate, and the incidence of maternal awareness using the isolated forearm technique (IFT). The postoperative interview was conducted between 12~24h after operation. RESULTS: The incidence of maternal awareness signaled by flexing fingers in response to voice commands were significantly lower in the T-E group (20% after induction, no response during other times) than the P group (45% after induction, then 35%, 30%, after 5, 10 min delivery respectively). Seven patients had postoperative recall of introspective awareness in the P group but no patients in the T-E group. The 1 min Apgar score of the newborn were significantly lower in the P group than the T-E group but both groups were within normal range. CONCLUSIONS: Our date indicated that, in comparison with thiopental-enflurane, propofol infusion (6 mg/kg/h) were associated with a greater incidence of awareness during surgery and recall.

We report a case of squamous cell carcinoma arising in giant porokeratosis in an 88-year-old woman. She had a 20 × 12 cm sized erythematous scaly patch with central ulceration on the right parietal area. On histopathologic examination, a skin biopsy specimen from the peripheral ridge of erythematous lesion revealed porokeratosis, and a specimen from the central ulceration showed well differentiated squamous cell carcinoma.

An outbreak of dermatosis occurred at a machinery manufacture factory in kyongju on Aug 1995. Authors conducted a questionnaire survey among 92 workers in the factory and a dermatologist examined their skin lesions. Authors also collected moths and identified them. The results are as follows; 1. Forty-two cases of dermatosis were identified with attack rate of 45.7%. Attack rate was not different by company, age, sex, educational level and duration of employment. Attack rate was 47.8% among productive workers, 25.0% among clerical workers and 100.0% among patrolmen. 2. Two cases among 42 dermatosis cases and three subjects among 50 non-cases had a history of same dermatosis last year. Four of dermatosis cases had a history of dermatosis among their family members. 3. skin lesions of the cases were scattered or grouped rice-sized erythematous papules or vesicles. Duration of dermatosis from the onset to the time of survey was from one day to more than 30 days. The most frequent site of skin lesion was the arms(81.0%), and it was also observed at the neck(47.6%), abdomen(45.2%), chest(42.9%), legs(38.1%) and back(35.7%). skin lesion was aggravated with sweating(31.0%), after shower(16.7%) and with scratching(l1.9%). 4. Moths were collected and identified as Euproetis subflava(Bremer). Many poisons stings were observed on their wngs which is harmful to human. 5. Contact with moths' wing droppings to two authors on their forearms for provocation resulted in severe immediate pain followed by prolonged pruritus. Erythematous macules quickly appeared and suoceeded by firm wheal-like red papules. Authors thought that the outbreak of dermatosis was brought about by Euproetix subflava(Bremer). Further studies on the factors contributing to the prosperity of the moths in this area are needed.
