Hysterosalphingography has proven to be an important diagnostic method for over 50 years. It has an established role in the diagnosis and treatment of infertility, tubal pathology, and in the evaluation of intrauterine disease and uterine anomaly. Radiologic analysis of uterus and cervix was made on 135 cases of hysterosalphingogram taken at the department of Radiology, Keimyung University hospital from January, 1983 to December, 1985.
닭肝의 Phosphoenolpyruvate Carboxykinase의 時差變動에 관하여
尹聖道,曺準承 慶北大學校 醫科大學 1975 慶北醫大誌 Vol.16 No.2
닭肝의 cytoplasmic PEP carboxykinase의 季節 및 日中變動을 調査하고 그 機轉의 一端을 究明하여 다음과 같은 結果를 얻었다. 1. 닭肝의 이 酵素는 季節的인 變動을 나타내었다. enzyme activity는 12月에서 4月까지는 높았고 그 以外 時間에는 낮은 傾向을 보였다. 2. 이 activity는 또한 日中變動을 나타내었으며 아침에는 높고 저녁에는 낮았다. 3. 이 circadian rhythm은 攝食과 關連이 있었다. 卽 攝食時間을 變更시키면 리듬의 時期가 變動하였으며, 絶食시키면 circadian decrease가, glucose를 주면 circadian increase가 沮止되었다. 4. 이 酵素의 circadin increase는 actinomycin D에 의해서 抑制되었다. This sudy is to observe the circadian variation of chicken liver phosphonenolpyruvate carboxykinase(EC 4.1.1.32) activity and to analyse the influence of fasting, actinomyciin D, and glucose. The results obtained were summerized as follows; 1. The enzyme activity generally exhibited annual rhythmic variation with the high activity in the cold season (Dec.-Apr.) and the low activity in the hot season(May-Nov.), though the ranges of the activity were broad. 2. The enzyme also showed a diurnal variation with a crest at 0800 and trought at 2000, though the amplitude varied with the season. 3. The circadian rhythm of the enzyme activity varied in reversed phase with fasting or changes of feeding time. Cirdadian increase of the enzyme activity was inhibtied by actinomycin D and glucose.

The prevalence of Hbs antigenemia among 917 parturients screened in antenatal check at Keimyung Univ. Dong San Medical Center Taegu, Korea was 6.1%. Identifiable risk factors could not be found for over 82% of asymptomatic hepatis B surface antigen positive women. The presence of Hbe Ag seemed related to HBV vertical transmission & infectivity. Considering cost effectiveness & significant risk of perinatal transmission, comprehensive antepartum Hbs Ag screening is recommanded & more over immune prophylaxis is also mandatory to eradicate the future hepatitis B transmission among populations.
Pregnancy Associated Osteoporosis
윤성도 대한골다공증학회 2009 Osteoporosis and Sarcopenia Vol.7 No.3
It is thought that normal pregnancy does not cause osteopenia or osteoporosis in most women. Although there is bone loss during the first 6 months of lactation, subsequent recovery is generally expected. It has been reported that women can develop pregnancy-associated idiopathic osteoporosis during pregnancy or while lactating. The cause of this is controversial, but most authorities believe that pregnancy unmasks a pre-existing bone disease. In more than one-half of pregnant women, no apparent cause for osteoporosis can be identified. Some known causes of pregnancy-associated idiopathic osteoporosis include heparin therapy, prolonged bed rest, and corticosteroid therapy. In a few cases, overt hyperparathyroidism or thyrotoxicosis eventually develops. Bone mass is the main predictor of fractures. Maximum bone-mass accumulation is reached by the end of the second decade, just before the childbearing age. Pregnancy and lactation are associated with considerable changes in calcium homeostasis to meet fetal calcium demands for skeletal calcification. Although renal conservation of calcium is less efficient during pregnancy, the active absorption of calcium by the intestine doubles by 20weeks. In theory, since there is 30~35g of calcium in the full-term neonate, and considering that the maternal skeleton contains 1,000g of calcium, the effect on the mother should be relatively slight. To help understand the effects of pregnancy on bone turnover and osteoporosis, the author has reviewed the some literature and studies have utilized biochemical markers of bone formation, resorption, and bone turnover before, during, and after pregnancy.

Thanatophoric dwarfism is the term applied to a distinctive, lethal form of bone dysplasia described by Maroteax et al. in 1967. Authors experienced a case of fetal dwarfism on antenatal ultrasound and flat abdominal X-ray examinations. The baby was delivered by induction of labor. Diagnosis was confirmed to thanatophoric dwarfism by clinical features, radiological and autopsy findings.
