The Mo¨ssbauer effect studies of the quenched glass and heat-treated glasses were performed. The Debye and Einstien temperatures of the quenched glass, determined using the center shift and kinetic temperature, are 540K and 430K respectively. The X-ray diffraction pattern showed that the heat-treated glasses were crystallized. Form the isomer shift of the heat-treated glasses, it was concluded that the Fe^(3+) ion is predominantly octahedrally coordinated.

In order to clarify how the treadmill program influences the blood pressure, serum lipids, and cardiopulmonary function of the hypertensive adult, total 34 subjects-26 male subjects and 8 female subjects- in an age group of 30-65 year joined in a program of treadmill exercise which was carried out for 12 weeks sequentially. The intensity of exercise given to the subjects was within 50-80% of their maximun oxygen uptake, and they had exercise for 20-40 minutes a day which was executed for 5 days a week. And in order to find out any difference or change happening for the application of the program to the subjects, blood pressure, physical composition or structure, serum lipids, metabolism, and cardiopulmonary function were checked before and after exercise and compared with reference to the changes of blood pressure, heart rate, and oxygen uptake while the subjects were taking exercise. And those data were reviewed in terms of a male group and female group and a total group which includes both male and female subjects. Also the data were reviewed in an age group of less than 50 years and another age group of more than 50 years. And additionally, the data were reviewed in three groups concerning systolic blood pressure; a group whose systolic blood pressure decreased by 0-9 mmHg, another group whose systolic blood pressure decreased by 10-19 mmHg, and another group whose systolic blood pressure decreased more than 20 mmHg. And also they were reviewed in three groups regarding diastolic blood pressure; a group whose diastolic blood pressure decreased by 0-5 mmHg, and another group whose diastolic blood pressure decreased by 6-10 mmHg, and another group whose diastolic blood pressure decreased more than 11 mmHg. In the result of such a study, findings are as follows : 1.It appeared that systolic pressure and diastolic pressure in a stable condition after the execution of the program significantly decreased(p<0.001) in the male group and the total group, with also decreased heart rate showing as well in these groups. 2.It appeared that forced vital capacity(FVC), forced expiratory volume for 1 second percent(FEV1), and maximum voluntary ventilation(MVV) after the execution of the program significantly increased (p<0.05, p<0.01) in the male group and the total group, and however only maximum voluntary ventilation increased in the female group. Regarding age, FEV1 increased more in the age group of less than 50 years than in the age group of more than 50 years. 3.Body weight, persent body fat, and fat body weight decreased in all the groups-the male group, female group, and total group since the execution of exercise, and body fluids incresed only in the male group and total group. Regarding age, persent body fat decreased more in the male group whose age is less than 50 years and in the female group whose age is more than 50 years than in other groups. Regarding the decrease rate of blood pressure, the group in that systolic blood pressure decreased more than 20 mmHg in male body fat rate and the group in that diastolic blood pressure decreased more than 11 mmHg showed more decrease rare of blood pressure than other groups. 4.Total cholesterol(TCH), low density lipids protein(LDL), ratio of total cholesterol to high density lipids protein and triglycerides(TG) decreased in all the groups- the male group, female group and total group since the execution of exercise, however high density lipids protein increasing. Regarding age, total cholesterol decreased more in both the male and female groups whose age in under 50 years than both the male and female group whose age is above 50 years. And triglycerides decreased more in the female group whose age is under 50 than in the female group whose age is above 50. Regarding the decrease rare of blood pressure, the group in the systolic blood pressure decreased more than 20 mmHg in male triglycerides and the group in that diastolic blood pressure decreased within 6-11 mmHg showed more decrease rate of blood pressure than other groups. 5.Heart rate in exercise decreased after the execution of the program than before the execution of the program. 6.The increase of systolic blood pressure in exercise decreased in all the groups-the male group, female group, and total group, howere no change showing in their diastolic blood pressure. 7.The amount of oxygen uptake in exercise and after exercise incensed in all the groups- the male group, female group, and total group after the execution of the program than before the execution of the program. 8.Maximum oxygen uptake significantly increased(p<0.01) in all the groups-the male group, female group, and total group after the execution of the program. 9.A regression equation showing the relations between systolic blood pressure, heart rate and oxygen uptake was obtained, and it indcated a close relation between them. Based on the finding indicated so far, those results after the application of the treadmill exercise program to hypertensive adults such as decrease in blood pressure, weight, body fat rate, and body fat, increase of body fluids, improvement of the metabolism of serum lipids and cardiopulmonary function, and more increase of both systolic blood pressurea and diastolic blood pressure in the male group whose age is less than 50 years than in the male group whose age is more than 50 year-all these indicates significance. And also, based on the regression equation, the possibility to estimate heart rate and oxygen uptake with only systolic blood pressure is a noteworthy result of this study.

This study was undertaken for the clinical evaluation and statistical analysis on the 38 cases of placenta previa who were admitted and treated from March 1, 1988 to Feb. 28, 1991. The results were as follows : 1. The incidence of placenta previa was one per 53 deliveries or 1.90% 2. There were 57.9 % total placenta previa, 21.1 % partial placenta previa, 13.1 % low-lying placenta previa and 7.9% marginal placenta previa. 3. Placenta previa has occured more often in multipara (63.2%) than primigravida 4. More than one-third (38.8%) cases of placenta previa had delayed admission until labor occured for some time following vaginal spotting has first time been noticed. More instructive prenatal education should be emphasized 5. Lower segment transverse section rate was 63.2%, classical cesarean section rate was 15.8% and cesarean hysterectomy was 9.8%. The rest of them were treated by vaginal deliveries of 5 cases(13.2%) 6. The perinatal loss associated with placenta previa was considered still higher : the premature death was 15.8% and term death was 2.6%. The problem of prevention of prematurity still remains to be studied. 7. There was no maternal mortality in our study

In oriental medicine several valuabel prescriptions for hepatic diseases usually contained the Bupleuri Radix and Scutellariae Radix. The possible protective effect of these oriental herb on hepatotoxicity induced with benzo(a)pyrene(B(a)P) in vivo were examined. Water extracts of Bupleleuri Radix, Scutellariae Radix and the mixture of both Radix were separately administered by orally to rats with hepatic demage induced by B(a)P(0.1 mg/kg, i.p.) and their effects in the serum were biochemically investigated. B(a)P treated group had siginificantly increased AST, ALT, ALP and LDH activities of Radix, Scutellariae Radix significantly diminished these increased enzyme activities. Increased total lipid, triglyceride and total cholesterol contents of serum by B(a)P injection were decreased by administration of water extract of Bupleuri Radix, Scutellariae Radix and mixture. Favorable results of this experiments indicate that herb mixture can be considered as a good therapeutic agent for the treatment of hepatic injury.
