A statistical study was made on a series of 844 cases of abnormal genital bleedings, with the review of particular references of literature, which were complained chiefly from patients among 7991 cases of out-patients at Gynecological Department of Korea University Medical College Hospital during a period of 5 years from January, 1966 to December, 1970. The results obtained were as follows: 1) The incience of abnormal genital bleeding was 10.6 per-cent. 2) In causative factors of abnormal genital bleeding, there were 55.7 per-cent of anatomical factor, 17.4 per-cent of obstetrical cases which did not belong to obstetrical hemorrhage, 23.2 per-cent of functional uterine bleeding and 3.6 per-cent of other gynecological bleeding. 3) Abnormal genital bleeding cases were obtained in 28 per-cent of pregnancy disorder, 17 per-cent of inflammation of genital organs, 28 per-cent of the tumors of genital organs, (benign tumor 17 pre-cent and malignant tumor 11 per-cent) 23 per-cent of functional uterine bleeding and 4 per-cent of other causes. 4) In the endometrial findings of 54 cases of functional uterine bleeding, there were 85 per-cent of endometrial hyperplsia, 9 per-cent of secretory endmetrium and 6 per-cent of postmenopausal atrophic endometrium. 5) The largest age distribution of functional uterine bleeding was at the age group between 30 and 40.(32 per-cent) 6) The most frequent causative disease of abnormal genital bleeding was functional uterine bleeding, (23.3 per-cent), on the contrary, salpingitis, adnexitis and urethral caruncle were rarely associated abnormal genital bleeding. (0.3 per-cent and 9.5 per-cent respectively) 7) Abnormal genital bleeding was noted most frequently at the age group 30th(31.8 per-cent) and the lowest incidence was under the age of 20th.(2.3 per-cent) 8) The benign disease of genital organ was in 43 per-cent and in the malignant disease in 13 per-cent of all abnormal genital bleeding. 9) The cervical cancer was 75.5 per-cent, the corpus cancer 11.8per-cent, the ovarian cancer 4.9 per-cent and the choriocancer 7.8 per-cent of all abnormal genital bleedings. 10) The incidence of postmenopausal bleeding was 10.0 per-cent. The bleeding due to the malignant disease of genital organs was 40.5 per-cent, and the benign disease of genital organ 53.6 per-cent and undetermined causes 5.3 per-cent of all postmenpausal bleedings.
Resepine과 Human Chorionic Gonadotropin 이 家兎의 子宮및 골격근조직내 Catecholamine 含量에 미치는 影響

Catecholamine has various pharmacological effects. This might be due largely to its relation to the sympathetic nervous system. Reserpine has been widely used as a tranquilizer and anti-hypertensive drug in the obstetrical and gynecological field for last 20 years in spite of a number of untoward side effects affecting various organs. An attempt has been made to clarify the effects of reserpine on the catecholamine content in the uterine and skeletal muscle tissue of mature female albino rabbits weighing around 2㎏. A group of albino rabbits conditioned with 50 I.U./㎏ of H.C.G. and another group with 1.0㎎/㎏ of reserpine plus 50 I.U./㎏ of H.C.G. were observed in 24 hours after conditioning. Catecholamine content was determined by Shore and Olin method. The results obtained were as as follows: 1. The catecholamine content in the normal uterine tissue was 0.40 ㎍/gm, while that of the skeletal muscle tissue was 0.11 ㎍/gm. Therefore catecholamine content in the uterine tissue was much higher than that in the skeletal muscle tissue. 2. In the H.C.G. conditioned group, the catecholamine content in the uterine tissue showed decrease in content (0.13 ㎍/gm) as compared to the normal group and in the skeletal muscle tissue it showed a decrease (0.07 ㎍/gm) as compared to the normal rabbit group. 3. In the reserpine plus H.C.G. conditioned group, the catecholamine content in the uterine tissue was much more decreased in content(0.06 ㎍/gm) and the content in the skeletal muscle tissue showed a decrease (0.07 ㎍/gm) as compared to the normal rabbit group. 4. The catecholamine content in the uterine tissue showed decrease if treated with H.C.G. and much more decreased in the reserpine plus H.C.G. conditioned group. 5. The catecholamine content in the skeletal muscle tissue treated with H.C.G. and reserpine plus H.C.G. showed a decrease as compared to the normal rabbit group. 6. In the normal group, the catecholamine content in the uterine tissue was much higher than that in the skeletal muscle tissue and in the H.C.G. conditioned group, the catecholamine content in the uterine tissue was higher than that in the skeletal muscle tissue. In the reserpine plus H.C.G. conditioned group, the catecholamine content in he skeletal muscle tissue showed almost the same as that in the uterine tissue,
Ar/CF<sub>4</sub>/Cl<sub>2</sub> 플라즈마에 의한 CeO<sub>2</sub> 박막의 식각 특성 연구

In this work, the etching of $CeO_2$ thin films has been performed in an inductively coupled $Ar/CF_4/Cl_2$ plasma. The highest etch rate of the $CeO_2$ thin film ws 250 ${\AA}/min$ and the selectivity of CeO$_2$to SBT was 0.4 at a 10% additive $Cl_2$ into Ar/($Ar+CF_4$)gas mixing ratio of 0.8. From result of X-ray photoelectron spectroscopy (XPS) analysis, there are Ce-Cl and Ce-F bonding by chemical reaction between Cl, F and Ce. During the etching of $CeO_2$ thin films in $Ar/CF_4/Cl_2$ plama, Ce-Cl and Ce-F bond is formed, and these prodcuts can be removed by the physical bombardment of Ar ions. The 10% additive $Cl_2$ into the Ar/($Ar+CF_4$)gas mixing ratio of 0.8 could enhance the reaction between Cl, F and Ce.
