본 연구는 긴볼레기말 추출물의 항고지혈증 효과를 조사하기 위해 ICR 생쥐에 TritonWR-1339(TX) 복강주사로 인위적인 고지혈증을 유발시킨 후 긴볼레기말 추출물(30㎎/㎏)를 복강주사하여 시간의 경과에 따른 간세포내에서의 지방 축적 변화를 조직화학적으로 관찰하였다. TX 주사후 그물구조의 세포질출 가진 간세포가 간엽 전체에서 관찰되었고, 일부 간소엽에서는 간세포 손상으로 인한 간세포판 소실이 나타났다. 또한 간세포내 지방축척도 증가하여 전체 간소엽의 간세포에서 지방의 과출현을 확인 할 수 있었고, 지방의 크기도 대조군에 비해 증가된 것으로 관찰되었다. 그러나 긴볼레기말 추출물 주사군에서는 그물구조의 세포질을 가진 간세포의 수가 TX 주사군에 비해 감소되었고, 대부분의 간소엽에서 정상적인 간세포판의 배열을 확인할 수 있었다. 간세포내의 지방 축적과 크기도 감소된 경향으로 관찰되었다. 이상의 결과로 볼 때 해조류 긴볼레기말 추출물은 고지혈증이 유발된 생쥐 간세포 내에서의 과도한 지방축적을 감소시키는 항고지혈증 효과를 하는 것으로 사료된다. Hepatic tissues of ICR mouse were intraperitoneally injeced with Colpomenia bullosa(CB) Extract after Triton WR-1339(TX) injection were observed to investigate the antihyperlipermic effect of CB extract for hyperlipidemic hepatic tissue caused by destruction of lipid metabolism. The hepatic tissues were obtained at hour-24, 48, and 72 after TX injection with CB extract treatment. And then these specimen were fixed in 10% neutral buffer solution and were cryocut. The tissue stained by H&E for general morphology and sudan black B for lipid distribution. The increase of hepatocyte having rneshlike cytoplasm were shown in all hepatic lobules after TX injection and the hepatic plates were disappeared in the region of meshlike hepatocyte aggregation, But the hepatocyte having meshlike cytoplasm were disappeared and hapatic plate were rearranged in CB extract injected mouse. The number of blue black colored lipid drop in hepatic cytoplasm of mouse injected with TX were increased and the size of lipid drop were enlarged. But the number of lipid drop in hepatic cytoplasm of mouse treated CB extract were decreased and the size of lipid drop were diminished. As results indicated that the accumulation of lipid drop caused by TX injection were mitigated by the antihyperlipidermic effect of CB extract.

This study reviews reform tasks for developing the Chinese university education. Chinese university remains underdeveloped, compared with other countries with similar economy level. Difference in demand and supply of university education is an issue, confronting Chinese Higher Education. Chinese universities have been controlled by government's close supervision under old planned economy. This implies that Chinese higher education adopt free market system. Society and individuals as well as Central Government need to be involved in establishment and management of university. Private universities should be developed with policy support of Central Government. Free competition and supplementation are major directions which public and private universities should be developed and managed. Quality control and efficiency are a share of university authorities. Government's minimal control and university's autonomy are key reform tasks for developing Chinese university education and upgrading university quality.

腹腔鏡的 肝針生檢出血의 Absorbable Gelatin Sponge止血法에 關한 硏究

박규섭,玄振海 고려대학교 의과대학 1984 고려대 의대 잡지 Vol.21 No.1

Needle biopsy of the liver under direct vision of laparoscope if of proved value in the differential diagnosis of various hepatic lesions. But serious complication include uncontrollable hemorrhage from the biopsy site. On the other hand, newly introduced absorbable gelatin sponge, Gelfoam, have been used successfully for support as hemostasis in neurosurgery or vascular surgery. Therefore. The author tried to insert Gelfoam for support as hemostasis into the site of needle biopsy of the liver showing uncontrollable bleeding. For the purpose to evaluate above innovation, experimental and clinical studies were performed as following. In experimental study, needle biopsies of the liver were done on 24 rabbits, selecting the left posterior lobe as the biopsy site which was packed by Gelfoam, and the right anterior lobe as control site. Biopsy was done every 5 minutes interval on 4 rabbits, every 1 hour interval study on another 4 rabbits, and every 1 week interval on 16 rabbits till 4 weeks. As a clinical study, bleeding time, coagulation time, prothrombin time and bleeding time from the biopsy site after aspiration needle biopsy under the direct vision of laparoscope were measured in 6 cases of normal, 22 cases of hepatoma, 17 cases of liver cirrhosis, 10 cases of metastatic cancer, 9 cases of chronic active hepatitis, 2 cases of chronic persistent hepatitis, 2 cases of fatty liver and 1 case of acute viral hepatitis. In another 9 cases of various liver diseases who showed pulsatile or persistent bleeding over 10 minutes from the biopsy site, Gelfoam impaction at the biopsy site under direct vision of laparoscope was done and then measured bleeding time. The results were as follows. 1) In experimental study, tampon effect of Gelfoam was confirmed by collapse of hepatic cell cord around impacted Gelgoam in the biopsy site. 2) The bleeding time from the biopsy site had no direct relationship with the patient’s hemostatic data such as bleeding time, coagulation time and prothrombin time. And there was no significant difference in bleeding time from the biopsy site between normal group and various liver disease group. 3) Gelfoam packing into the biopsy site in 9 cases showing pulsatile or persistent bleeding more than 10 minutes controlled bleeding within 1 minute.

This research is to give light upon the cause of stagnated economy of Chonbuk province by comparing the interreginal conditions of economy mainly since 1960s which is the period between Japanese Colony and the development of this province, and to propose its measures to overcome it. Chonbuk region, Since its opening of Kunsan port, through the term of Japanese colony, had been degenerated into a relative area of stagnation compared with other areas due to land seizure and exploitation of agricultural products by Japan. Thus since the opening of port the structure of economy in Chonbuk region was deformed into that is typical monoculture from colonial exploitation. Of course, althrough the structure of Korean economy under Japanese colony was generally maimed through exploitative structure of economy, it was demonstrated by substantiation data, that Chonbuk region with its opulent exploited as a primary object area of exploitation by Japan. Deprived of its autogenous vitality and alienated even from "the age of development" for decades, economical structure of Chonbuk province couldn't but be still aggravated rather than improved. Eventurally the gap between present growing regions is more over deepening through the compound geometrical functions of various factors that restrict regional development of economy as analyzed above.
