  • A simpled and sensitive microplate enzyme immunoassay(EIA) was developed for the determination of progesterone concentration in serum, based on progesterone monoclonal antibody as anti-progesterone, horseradish peroxidase(HRP) as enzyme-label and tetramethylbenzidine(TMB) as substrate. The assay has a sensitivity of 5 pg-120pg/well and intra- and inter-assay coefficients of variation for progesterone standard curve (1.0ng~10.0ng/ml) were ranged 2.5~9.9% and 1.7.8.0%, respectively, determination coefficient of the regressio equation of our standard curve(R2=0.990$\pm$0.007) were high, and this is the same level as that of commercial kit(Hormonost Bio-Lab, Germany, R2=0.98~0.99). The progesterone concentration of serum determined by both kits (Work & Bio-Lab) were significantly correlated (r=0.95, P<0.01) although a little higher value were resulted in our kit than that of commercial kit. It generally is these results indicated that the microplate-EIA can be cused for the determination of progesterone in serum, as well as, for the determination of the early pregnancy diagnosis.

  • Objectives : The aim of this study was the collection of dietary treatments of atopic dermatitis Methods : We surveyed the western and oriental medical book concernig the atopic dermatitis. Results : The 20~30% of patients with atopic dermatitis have hypersensitivity reaction on the major food antigen. The food restriction to prevent allergy reaction need to take effect early during infancy and childhood. In oriental medicine, a heat-poison(熱毒) caused by food affects a fetus of pregnancy. So the food, the regimen and the harmony of the five tastes is stressed the need. When certain foods are restricted to prevent allergy reaction, infant and children with food related Atopic Dermatitis need extra dietary efforts to maintain optimal nutrition as they are in the growth period.

  • This study was carried out to produce monozygotic twin calves by transfer of bisected embryos. Four Korean native cattle donors were superovulated with FSH and flushed to collect embryos on day 6 or 7 of the estrus cycle. Morula and early blastocyst embryos showed 1 or 2 grade were bisected with microblade and each set of demi-embryos without zona pellucida were transferred nonsurgically to 10 recipients respectively. The results obtained were as follows; 1. Twenty four demi-embryos (92.3%) were separated from 13 original embryos and among them 20 demi-embryos (83.3%) had normal appearance without severe damage. 2. Four sets of fresh demi-embryos were transferred to 4 recipients and one recipient was twin pregnant 3. Six sets of frozen-thawed demi-embryos were transferred to 6 recipients. Two recipients were pregnant, one of them twin.

  • Objectives: The purpose of this study is to report a effect of herbal medicine at threatened abortion in the early stages of pregnancy. Methods: A 37-year-old female patient who had the abdomen pain with vaginal bleeding was taken Gyoaesamultang-gami and Antae-eum for 11 days at Dae-gu Haany University Hospital in Pohang. Results: During this treatment period, vaginal bleeding and abdomen pain were relieved. Also after all treatment, the effect had been continuing. Conclusions: Gyoaesamultang-gami is effective on threatened abortion. And the female patient deliver normally.

  • In 2021, a new chapter on the general management of glomerulonephritis (GN) was added to the Kidney Disease: Improving Global Outcomes (KDIGO). It emphasizes the importance of early general management of GN for improving long-term kidney outcomes and prognosis. The chapter introduces the management of glomerular diseases in 18 subchapters. Here, kidney biopsy for the diagnosis and evaluation of kidney function and the management of complications, such as hypertension, infection, and thrombosis, are presented. Moreover, the adverse effects of glucocorticoids and immunosuppressive therapy, which are commonly used drugs for glomerular disease, are mentioned, and a guideline for drug selection is presented. Each subtheme focused on items reflecting the interpretation of the "practice points" of the expert working group are introduced. In this review of the general treatment for GN in the KDIGO guidelines, excluding pregnancy and reproductive health, we focused on and compared various references pertaining to pediatric GN management.

  • 사람의 혈액중 혈청으로써 임신의 진행에 따른 단백질의 변화 양상을 조사함에 있어서 정상인 남자, 비임신 여자, 임신한 여자 및 분만 직후 여자의 혈청을 SDS/polyacrylamide gel 전기영동과 2차원 전기영동 및 아미노산분석을 시도하였다. 각 실험 방법에 의해 분석된 결과는 다음과 같다. 1. SDS/polyacrylamide gel 전기영동에 의해 분자량 약 10,000에서 110,000 dalton 사이의 정상인 남자와 비임신 여자를 비교하였을 때의 숫적 양상은 서로 동일하였으나 bands 3 (22,000 dalton)과 6(39,000)등은 남자에 있어서 여자보다 적은 양으로 나타났다. 비임신 여자와 2주 간격으로 혈액을 채취한 임신한 여자의 혈청단백질 패턴을 비교하면 여러 band들의 양적인 증감이 관찰되었다. 임심한 여자의 단백질은 비임신에 비해 band 3(22,000)이 16주까지는 비임신의 경우와 거의 비슷한 양상을 보였으나 18주부터 임신 말기까지는 단백질의 양이 계속하여 감소되었다. 반면 bands 4(24,000), 9(69,000), 10(70,000), 12(80,000), 13(83,000), 14(86,000), 15(91,000) 및 16(94,000)은 임신이 진행됨에 따라 일반적으로 증가되나 그 이후에는 약간씩 감소하였다. 분만 직후의 혈청단백질의 패턴을 임신 말기와 비교하였을 때 bands 12(80,000), 15(91,000) 및 16(94,000)들의 양이 비교적 증가하였고 여아를 분만한 경우 남아를 분만한 경우보다 bands 4(24,000), 7(51,000) 및 10(70,000)들의 단백질 양이 많음이 관찰되었다. 2. 2차원 전기영동으로 남자와 비임신 여자의 혈청단백질 패턴을 비교하면 spot a(22,000)의 3개의 spot가 남자에 있어서는 나타나지 않았고, spotc(39,000)의 군은 남자에 있어 여자보다 농도가 매우 낮았다. 임신한 여자에 있어 albumin이 임신 10주와 12주에 매우 감소하였고 그 이후에 다시 회복되었다. 그리고 spot f(70,000)는 임신 10주에 매우 감소 되었다가 그 이후에 증가되었다. 3. 각 군들의 아미노산을 분석한 결과 임신한 여자에 있어서 전반적으로 glutamic acid, lysine, aspartic acid, leucine 및 valine이 대체로 많은 양으로 나타났고, methionine, isoleucine 및 glycine이 대체로 적은 양을 가지는 것으로 나타났다. 전체 아미노산의 양은 임신중기에 현저히 증가하였다가 말기에는 중기에 비해 감소되었다. 이상의 결과를 볼 때 임신기간 중에는 모체의 혈청을 구성하는 단백질이 특정한기에 따라 증가하므로 임신한 여자의 혈청단백질을 조사함으로써 임신의 각기에 나타나는 독특한 단백질 양상 변화를 밝혀내는 동시에, 앞으로 좀더 연구함으로써 태아의 성을 단백질 패턴으로 명확히 구별해 낼 수 있을 것으로 생각된다.

  • In our previous study, overexpression of extracellular proteinase inhibitor (Expi) gene accelerated apoptosis of mammary epithelial cells, and induced expression of B cell activating factor (BAFF) gene. In this study, we found induction of BAFF-receptor (BAFF-R) gene expression in the Expi-transfected cells. A proliferation-inducing ligand (APRIL) gene is another TNF family member and the closest known relative of BAFF. We found induction of APRIL gene expression in the Expi-overexpressed apoptotic cells. NF-${\kappa}$B gene was also induced in the Expi-overexpressed cells. Expression patterns of BAFF and APRIL pathway-related genes were examined in in vivo mouse mammary gland at various reproductive stages. Expression levels of BAFF gene were very low at early pregnancy, increased from mid-pregnancy, and peaked at lactation, and thereafter decreased at involution stages of mammary gland. Expression of BAFF-R gene was highly induced in involution stages compared to lactation stages. Thus, expression patterns of BAFF-R gene were correlated to apoptotic status of mammary gland: active apoptosis of mammary epithelial cells occurs at involution stage of mammary gland. Expression levels of NF-${\kappa}$B gene were higher in involution stages compared to lactation stages. We analyzed mRNA levels of bcl-2 family genes from different stages of mammary development. Bcl-2 gene expression was relatively constant during lactation and involution stages. There was a slight increase in bcl-xL gene expression in involution stages compared to lactation state. Bax gene expression was highly induced in involution stage. Our results suggest that signaling pathways activated by both BAFF and ARRIL in mammary gland point towards NF-${\kappa}$B activation which causes upregulation of bax.
