수도(手稻)의 파종양식(播種樣式)과 파종량(播種量)이 이앙기용(移秧機用) 묘소질(苗素質)에 미치는 영향(影響)
김문규,김성래,안수봉,Kim, Moon-Kyu,Kim, Soung-Rai,Ahn, Su-Bong 충남대학교 농업과학연구소 1978 Korean Journal of Agricultural Science Vol.5 No.2
수도(水稻)의 성묘기계이앙(成苗機械移秧)에 알맞은 건묘(健苗)를 육성(育成)해 내고자 산파식(散播式)인 mat묘(苗)와 조파식(條播式)인 단책묘(短冊苗)의 우열(優劣)을 여러 파종량하(播種量下)에서 비교검토(比較檢討)한 바 다음과 같은 결과(結果)를 얻었다. 1. 20일묘(日苗)에서는 파종양식간(播種樣式間)에 생육상(生育相)과 묘소질(苗素質)의 차이(差異)를 별반 인정(認定)할 수 없었으나 30일묘(日苗)에서는 단책묘(短冊苗)가 mat묘(苗)보다 평균생장속도(平均生長速度)와 상대생장율(相對生長率)이 다같이 크고 묘(苗)의 건물중(乾物重), 탄수화함량(炭水化含量) 및 건물중대초장비율(乾物重對草長比率)도 무겁고 커서 건묘(健苗)의 소질(素質)을 가지고 있었다. 그러나 40일묘(日苗)에서는 그차이(差異)는 축소(縮小)되었으며 묘령(苗令)의 진전(進展)은 거의 인정(認定)할 수 없었다. 2. 묘(苗)의 생장량(生長量)은 박파(薄播)일수록 많고 밀파(密播)와의 차이(差異)는 육묘일수(育苗日數)가 연장(延長)됨에 따라 커졌으며 밀파(密播)의 한계(限界)는 단책묘(短冊苗)에서는 묘상자당(苗箱子當) 200cc이고, mat묘(苗)에서는 250cc 정도(程度)였었다. 3. 단책묘(短冊苗)는 mat묘(苗)보다 초장(草長)과 엽령(葉令)등의 변이계수(變異係數)가 큰 것으로 보아 묘(苗)의 균일성(均一性)은 mat묘(苗)보다 결여(缺如)되는 것 같으며 앞으로 검토(檢討)를 요(要)할 것으로 사료(思料)된다. In order to get healthy seedling of rice suitable for rice transplanter, the growing characteristics of the seedling grown under different growing days and sowing densities were invesigated and the results obtained were summarized as follows; In the 20 days old seedling, the difference of growing state of seed ling and its characteristics between the two types of nursery bed was not found, but for the 30 days old seedling, both of the crop growth rate and the relative growth rate on the band-type nursery bed appeared higher than those on the mat-type nursery bed. And also, "the dry weight, the content of cardohydrate and the ratio of dry weight to plant height of the seedling grown on the band-type nursery bed were much higher than those on the mat-type nursery bed, however the amount of difference of seedling characteristics between two types of nursery bed was decreased for 40 days old seedling and leaf number was not increased. The amount of the seedling growth was increased with less density of sowing and for the difference between the higher and the less density, the difference getting bigger with the longer nursery days. The maximum density of sowing was approximately 200cc per nursery case on the band-type nursery bed and 250cc per nursery case on the mat-type nursery bed. It was seemed that the growing uniformity of the seedling grown on the mat-type nursery bed was better than that on the band- type nursery bed, As the coefficient of variation of the plant height and the leaf numbers of the seedling grown on the band- type nursery bed was higher than that on the mat-type nursery bed.

냉동.해빙한 생쥐배아의 발생에 미치는 해빙속도와 퇴화할구의 영향
김문규,이호준,이승재,전종영,Kim, Moon-Kyoo,Lee, Ho-Joon,Lee, Seung-Jae,Jun, Jong-Young 대한생식의학회 1987 Clinical and Experimental Reproductive Medicine Vol.14 No.1
The present experiments have been bone to verify the effects of the warming rate and the degenerated blastomere(s) on further development of the frozen and thawed 4- and 8-cell mouse embryos. The embryos obtained from the mouse superovulated and mated were frozen in the solution of 15M DMSO in PBS containing 10% FCS at a slowly cooling rate($0.3^{\circ}C/min$). Two methods of warming slowly($8^{\circ}C/min$) and quickly ($450^{\circ}C/min$) were applied for thawing embryos. The thawed embryos were grouped according to the number of healthy blastomere(s) in the embryos. Some of the embryos were eliminated their degenerated blastomere(s) by means of a micromanipulation technique. The embryos were examined their developmental phases after 48 or 72 hrs incubation. The rates of blastocyst development from the frozen and thawed 4- and 8-cell embryos were 72.7% and 73.5%, respectively in case of thawing slowly, and were 78.9% and 80.0%, respectively in case of thawing quickly. The rate in case of thawing quickly was significantly higher than that in case of thawing slowly. The rates of blastocyst development from the frozen and thawed 4- and 8-cell embryos eliminated their degenerated blastomere(s) increased 5.9% and 24.4%, respectively compared with those of control groups not eliminated. The more number of degenerated blastomere(s) were eliminated from the embryos, the higher rate of blastocyst development was shown. It may be concluded from the results that the quickly thawing method is better for increasing survival rate than the slowly thawing one, and that the degenerated blastomere(s) in the frozen and thawed embryos affects as an interfering factor for further development of the embryos.

돼지 난포내 Alkaline Phosphatase 및 Adenosine Triphosphatase의 활성부위와 활성도
김문규,계명찬,윤현수,김종흡,Kim, Moon-Kyoo,Gye, Myung-Chan,Yoon, Hyun-Soo,Kim, Jong-Heup 대한생식의학회 1991 Clinical and Experimental Reproductive Medicine Vol.18 No.2
In order to study the growth and maturation of ovarian follicle, the localization and activity of alkaline phosphatase(ALPase) and adenosine triphosphatase(ATPase) of the granulosa cells and theca layer were examined according to the follicle size, the follicle state and the ovarian cyclic phase in pig. Theca interna of the small follicles was more heavyly localized with reaction product by the activites of ALPase and ATPase than that of the large follicles. It is assumed that, as the follicles proceed to growth and maturation, antrum formation is the result of the follicular fluid accumulation by means of active transport by the activities of ALPase and ATPase in theca interna. The activities of ALPase and ATPase in atretic follicles were higher than those of normal follicles. These results imply that the mechanisms of follicle maturation and atresia are different according to the phase of ovarian cycle.

영아때 방광요관역류 환아로 진단된 남아중 2세가 넘어 후천적으로 신반흔이 급격히 악화되는 경우는 드물다. 본 증례는 생후 4개월 때 첫 열성 요로감염으로 입원하여, 왼쪽 5등급 방광요관역류로 진단되었고, 부모가 수술을 원치 않아 2년간 예방적 항생제 요법만 시행받았다. 생후 29개월 때 열성 요로감염이 한 차례 재발하였고, 이후 3년간 추적관찰되지 않았다. 이 후, 5세 때 본원을 방문하여 신장초음파, DMSA 신스캔, 배뇨성 방광요도조영술을 재시행받았다. 추적 DMSA 신스캔에서 왼쪽 신상대섭취율이 생후 2세경 38%였으나, 8%까지 떨어졌으며, 왼쪽 방광요관역류는 4등급으로 남아있었다. 현재 방광요관역류의 수술적 요법이 신기능의 예후와 관련이 없다고 알려져 있으나, 이런 증례를 볼 때, 아직은 신반흔을 동반한 고등급의 방광요관역류 환자들에게 수술적 요법을 권유하는 것이 임상의들에겐 타당하다고 볼 수 있으며, 어떤 치료요법이 선택되어지든 상관없이 첫 요로감염 이후 환자를 장기적인 추적 관찰하는 것이 중요하다고 사려된다. Abrupt progression of renal scarring associated with vesicoureteral reflux (VUR) is rare in males over 2 years old of age. We report a 5 year old boy with sustained unilateral high grade VUR who experienced abrupt progression of renal scarring; he had a relative renal radionuclide uptake of 38% at 2 years of age that dropped to 8% after three years. Per his parent's wishes, he took prophylactic antibiotics for 25 months after his first febrile urinary tract infection (UTI) at 4 months old without surgical management. One episode of recurrent breakthrough infection occurred at the age of 2 years. This observation reminds us that a recommending surgical management for sustained high grade VUR associated with renal scarring might be needed. Close follow up of DMSA for renal scanning, and long term follow up of patients after the first febrile UTI are important.
