The aim of this study is to know the status of possession and utilization of A.V. aids in eight medical colleges located in Seoul in the year of 1979. And the result obtained as follows; 1) Th kind of A.V. aids possessed in 8 medical colleges was 12 kinds such as Simple Slide Projector, Film Strip Projector, Micro Slide Projector, Sound Film Strip Projector, Over Head Projector, Opaque Projector, Movie Projector, Film Loop Player, Cassette Tape Recorder, Open Reel Tape Recorder, V.T.R. Models. 2) The prevalent kind of A.V. aids in number in medical education was Simple Slide Projector(139), Cassette Tape Recorder(86), Over Head Projector(37), Film Strip Projector(21), and Movie Projector(15). 3) Simple Slide Projector, Over Head Projector and Models were the A.V aids possessed by all 8 medical colleges and Simple Slide Projector was the Equipment utilized by all colleges. 4) In number, one-third of A.V. aids possessed by colleges was utilized in medical education during the semesters in 1979. 5) The utility rate of A.V. aids from freshman and sophmore education during the second semester, 1979 was varied from 30.0% to 91.0% according to colleges and the average rate was 57%. 6) The utility rate of Simple Slide Projector was 52.0% and the rate of other kinds of A.V. aids were varied from 1.1% to 3.5%.

In order to obtain condition for in vitro fertilization of human ovum,it is necessary the quality control and the close surveillance of culture media. Since the current standard quality control procedure using mouse embruo is time-consuming and expensive method,more convenient and economic quality contro method has been required. Therefore, in the present study, human sperm was used to assess the acceptability of cord serum used as a supplement for the culture media. The survival index of human sperm was monitored by computer and the results of the present study were compared with the standared method using mouse embryo. The results are as follows: 1. The development of mouse 2-cell embryo showed that the acceptability rate was 86.9%345 mouse 2-cell embryos 2-cell embryo showed the development from 40% to 100% in 23 sera: 20sera were accptable and 3 sera were unacceptable. 2. In human sperm motility test, 16 sera were classified as acceptable ones and the 7 sera were unacceptable ones; the acceptability rates was 69.5%. 3. Mose of the sera which were admitted as acceptable ones in mouse embryo method were also acceptable in human sperm motility test. Moreover they are more sensitive. The conclusion of the present study is that human sperm motility test is more sensitive, convenient and economic than the method using mouse embryo. Therefore it is expected that human sperm can substitute the cumbersome mouse embryo method in quality control of cord sera for in vitro fertilization.

조기진통을 동반한 환자 (실험군) 42례와 거의 동일한 임신연령의 정상임산부 (대조군) 42례 를 대상으로 혈청 PGE2, PGF2a 및 estradiol농도를 각각 방사면역측정법으로 측정하여 비 교, 연구분석한 결과 다음과 같은 결론은 얻었다. 1. 조기진통호나자의 혈청 PGE2 및 PGF2a 평균농도는 각각 316.169±18.831 pg/ml, 19.108±1.471ng/ml로서 현저하게 증가되어 잇었으며 대조군에 비하여 유의한 차이가 있었 다. 그러나 조기진통환자의 혈청 estradiol평균농도는 6.448±0.153ng/ml로써 대조군에 비하 여 차이는 없었다. 2. 조기진통 환자중 ritodrine치료에 성공한 레에서 치료전 혈청 PGF2a평균농도 22.378±4.063ng/ml는 치료후 혈청 PGF2a평균농도 12.433±2.736ng/ml에 비하여 유의한 차이 가 있었으며 현저하게 감소되어 잇었다. 그러나 치료후의 혈청 PGE2 및 estradiol평균농도는 치료전에 비하여 차이가 없었다. 3. 조기진통 억제치료에 성공한 군과 실패한 군에서 혈청 PGE2의 평균농도는 유의한 차이 가 잇었으나 오히려 성공한 군에서 약간 높은 경향이 보였고, 혈청 PGF2a 및 estradiol평균 농도는 성공군과 실패군에 있어서 차이는 없었다. 4. 조기진통 억제치료에 실패한 례에서 혈청 PGE2 농도와 자궁경관 개대와의 관계는 관계 가 없으나, 혈청 PGF2a농도의 상승도가 높아질수록 자궁경관 개대는 현저하게 진행되어 있 엇으며 유의한 관계가 있엇다. 그리고 자궁경관 소실에 다른 혈청 PGF2a농도는 PGF2a농도 가 증가함에 따라 자궁경관 소실은 현저하게 진전된어 잇었으며 유의한 관계를 보여주었다. 그러나 혈청 PGE2 및 estradiol농도는 관계가 없는 것으로 나타났다. 이상 소견으로 보아 혈청 PGF2a농도의 측정은 조기에 조기진통의 발생예측과 조기진통 억 제치료의 성공적 치료를 예측하는데 권장할 수 있는 유용한 방법이라고 사료된다. 1. The means of serumProstaglandin E2, Prostaglandin F2a concetrations of the patients during the preterm labor (316.169±18.831 pg/ml, 19.108±1.471ng/ml) were significantly higher respectively than those of women in normal pregnancy of similar gestational age (250.271±21.746 pg/ml; n=42; p<0.01, 14.485±1.246 ng/ml ; n=42 ; P<0.05). No differences were observed between the two groups in the estradiol concentrations by paired test. 2. A significantly reduction in serum F2a concentrations occured in patients successfully treated with ritodrine (p<0.05). No significantly difference were observed between the plasma Prostaglandin E2, Estradiol concentrtions. 3. No significantly difference in initial serum prostaglandin F2a concentrations were observed between between treatment success population (treated preterm labor) and treatment failure one . 4. In the treatment failure population (n-21) there was a rise in plasma Prostaglandin F2a concentrations with increasing cervical dilatation and cervical effacement (p<0.05) there was no correlation between the cervical dilatation and the serum Prostaglandin E2 concentrations.
