The interaction of vortex with a free surface affects many geophysical and environmental flow, including th mixing of pollutants in rivers. Visualized experimental results utilizing LIF technique are discussed for the purpose of characterization of vortex pair interaction with a clean and contaminated free surfaces and rigid, no-slip boundary. The result is that the vortex pair is stable and two-dimensional during the interaction with a clean free surface. However, when the surface is contaminated by a relatively viscous monolayer, the vortex dynamics are significantly altered, resulting in rebounding due to secondary vortex. When a solid plate is brought down to make contact with the clean free surface to provide a no-slip boundary condition, the pair displays similar dynamics to the contaminated surface case but the secondary vortices are somewhat stronger. For both contaminated and rigid surface cases, vortex breakdowns is observed.

허승곤,이규창 대한신경외과학회 1987 Journal of Korean neurosurgical society Vol.16 No.4

The effect of the calcium antagonist nimodipine on the feline cerebral cortical blood flow in experimentally induced subarachnoid hemorrhage(SAH) was studied. Cerebral cortical blood flow was measured in the middle cerebral arterial territory at specified intervals by the hydrogen clearance method. SAH was induced 25 cats by a slow injection of fresh autogenous arterial blood into the cisterna magna. Twenty-five cats were divided into 5 groups of 5 cats each according to the timing of the cerebral cortical blood flow measurements after SAH ; immediate(Group la, lb), 24 hours(Group 2), 48 hours(Group 3) and 7 days (Group 4). Cerebral cortical blood flow decreased by 55.5%, 39.2%, 41.4% and 38.3% from pre-SAH levels in each group respectively. During nimodipine infusion(1㎍/㎏/min) cerebral cortical flow increased by 89.0%, 51.8%, 87.5% and 24.5% from pre-nimodipine infusion levels in each group respectively. Mean arterial blood pressure(MABP) after cisternal blood injection increased by 6.5% from pre-SAH levels, and MABP during nimodipine infusion decreased by 15.4% from pre-Nimodipine infusion levels. The calcium antagonist nimodipine increased cerebral cortical blood flow significantly in experimentally induced SAH without considerable change of MABP. Results are considered promising for trials in the treatment and prevention of cerebral ischemia caused by vasospasm following SAH.

γ-Glutamyltransferase(GGT: E.C. 2.3.2.2.) is a glycoprotein enzyme which is involved in glutathione metabolism and amino acid transport through the plasma membrane. It is distributed widely in several organs including liver, kidney, pancrease and brain. GGTs derived from the brain of Wister rats and BALB/c mice were biochemically purified to a specific activity of 4246.2, 862.1 units per mg of protein, a purification folds 93.7, 43.8 and the final yield 65.8, 44.0% respectively. Electrophoretic pattern of purified GGTs from rats and mice brain shows very similar protein fraction each other. We have produced six monoclonal antibodies(GGT-MAb 1-6) against 2-acetamidofluorene treated rat liver GGT. Using these GGT-MAb 1-6 we performed immunohistochemistry(IHC) to study the distribution of GGY isozymes in normal tissues of rat brain and in ncoplastic tissues of human brain. The results indicated that human brain GGT was localized in pericytes of blood-brain barrier, especially in the blood-rich portion of the brain(e.g. cerebellum of rat, meningioma and craniopharyngioma of human). Therefore these MAbs may be used to evaluate the distribution of GGT isozymes in different tissues.

간척지에서 벼 담수직파재배시 입모 향상을 위하여 토양 염 농도별 적정 최아 정도를 구명하기 위하여 시험한 결과는 다음과 같다. 가. 입모수는 저염 토양은 건종자 파종에서만 적었고 그 외 처리에서는 비슷하였으며, 중염 토양은 반대로 최아 0㎜와 건종자 파종에서 많았다. 나. 출수기는 저염 토양에서는 최아 4㎜가 8월 18일인데 비하여 2 ㎜와, 0 ㎜에서는 같았으나 소독후 건조종자 파종에서는 1일이 늦었으며. 중염 토양에서는 최아 4㎜에 비해 2㎜는 같았고 건조종자 파송에서는 1일이 늦었으나 0㎜ 파송에서는 오히려 1일이 빨랐다. 다. 저염 토양에서는 ㎡당립수가 최아 4>2>0㎜>건종자 순으로 많아 쌀 수량도 최아2~4 ㎜에서 많았으며, 중염 토양에서는 도복에 강하고 등숙비율이 높은 최아 0㎜와 건 조종자 파송에서 쌀 수량이 많았다. 따라서 저염 토양에서는 최아 2~4㎜가 적당하고, 중염 토양에서는 최아 0㎜ 또는 소독 후 건조종자 파종이 적당할 것으로 판단된다. This study was conducted to examine an appropriate pregermination treatment of rice seeds for wet seeding on the wet surface of a reclaimed saline soil. It was conducted at the Gyehwado Substation of the Honam Agricultural Research Institute in 2002~2003. Two soil saline solutions (0~0.1% NaCl and 0.3~0.4% NaCl) and four pregermination seed treatments (nonsoaking, water absorption only, 2 ㎜ pregerminated, and 4 ㎜ pregerminated) were used. The experiment was carried out in a split plot design with three replications. At low soil salinity (0~0.1% NaCl), the number of spikelets and the percentage of ripened grain increased with a longer sprouting length of rice seed compared with that of nonsoaking (dry seeds) and water absorption only. Pregerminated seed treatments showed significant high rice yield performance in low saline conditions indicating pregerminated treatments are necessary for good seedling establishment and growth of rice. However, rice seeds treated with nonsoaking and water absorption only had higher yield performance in a medium soil salinity level (0.3~0.4%) than the pregerminated ones. This result indicated that pregerminated seeds seeded under a medium soil salinity level could have damaged shoot tips and roots, thus the growth would be retarded and soaking seeds float because of high soil salinity.

Fourty-seven patients with non-aneurysmal spontaneous subarachnoid hemorrhage were reviewed retrospectively. Attention was directed to the distribution and amount of subarachnoid hemorrhage on computerized tomography scans. Though the hemorrage could be distributed in all cisterns, the frequency and amount of hemorrhage were higher in infratentorial cisterns than in supratentorial cisterns. Among infratentorial cisterns, the hemorrhage was distributed to cisterns around the brainstem mainly and it had a predilection for interpeduncular cistern. Also the telangiectasia of thalamoperforating artery might be one of the causes of non-aneurysmal spontaneous subarachnoid hemorrhage.

Background and Objectives: Immunolabelling of interstitial Cajal(IC) cells in the intestinal wall has recently been developed by using a specific marker, the anti-c-Kit antibody. Substance-P is a well-known neurotransmitter in the gastro-intestinal tract. Since the gastro-intestinal wall structures have already been well documented in the guinea pig, immunohistochemistry was done for the c-Kit-positive IC network and substance-P receptor(NK1R) in an attempt to provide a morphological basis for the mechanism regulating gastro-intestinal movement. Materials and Methods: Cryosection and whole-mount preparations of guinea pig small intestine and colon were single and double immunolabelled using the anti-c-Kit and NK1R antibodies. Immunolabelled specimens were observed under a confocal laser scanning microscope. Results : According to a three dimensional reconstruction study, it was found that (1) the c-Kit-positive celluar networks were widely distributed in the intestinal wall, (2) c-Kit-positive celluar networks encircled the ganlion, with strands in reticular configurations, and (3) the c-Kit-positive cells showed colocalization with NK1R in circular muscle(CM), not myenteric plexus(MY). Conclusion: The charateristic profiles of IC containing c-Kit-positive celluar networks and the relationship between c-Kit-positive and NK1R-positive structures provide a morphological basis upon the mechanism regulating gastro-intestinal motility.
