A study was planned to analyze amino acid in target structure -the septal mucleus-of hippocampectomized rats by high-performance liquid chromatograph (HPLC). 33 female rats were divided into 3 groups, of which 8 rats had their hippocampal tissue on both sides removed through an opening in the parieto-occipital cortex (hippocampal group), 7 rats received damage to the parieto-occipital cortex only (cortical control group), and 8 rats serveed as normal control animals. One week later, the animals were sacrificed by decapitationin the cold room. Two to three mg of tissue was obtained from the septal nucleus in one side of the brain. The tissue three mg of tissue was obtained from the septal nucleus in one side of the brain. The tissue samples were homogenized in 200 of 0.5M perchloric acid in 1mM EDTA with ground-glass homogenizers. After centrifugation at 3.500 rpm for 15 min, an aliquot of 80 supernatant was neutralized with 40㎕ of 2.0M KHCO and then centrifuged again at 3,500 rpm for 10min. An aliquot of 20㎕ was taken and diluted with 350㎕ β-mercaptopropionic acid in 10 ml of 100 mM sodium borate buffer (Ph 9.1) and 350㎕ of OPA solved in ethanol which was diluted with 10ml of 100 mM sodium borate buffer (Ph 9.1) Then 400㎕ of the resulting sample was injected auto injector. Peak areas were automatically integrated and calculated by chromatopac. In the septal nucleus, aspartate increased a little in the hippocampla group and the cortical control group than in the normal control group . while there were no significant difference between the 3 groups. Glutamate decreased significantly in the hippocampla group than in the normal control group (P<0.001) and the cortical control group (P<0.005), while there were no significant difference between the 2 control groups. In the serine, glycine, threonine and alanine, the differences among 3 group values were nonsignificant. It is inferred from the above mentioned results that excitatory transmitter substances employ the glutamate in the septal nucleus, and that the hippocampus was facilitatory to the septal nucleus.

본 연구소에서는 현재 CD34^(+) 세포의 정량에 사용되고 있는 4가지 서로 다른 방법을 가지고 골수에 적용하여 그 결과를 비교하였다. 각각의 방법들이 편리한 점과 불리한 점들을 가지고 있었지만, 통계적으로는 유의한 차이를 보이지 않았다. 1) CD34-PE/CD45-FITC 방법13(ISHAGE: International Society of Hematotherapy and Graft Engineering), 2) CD34-PE/CD14-FITC 방법, 3) CD34-PE/CD14-FITC/CD45-PerCP 방법, 4) DNA dye/CD34-PE/CD45-PerCP4(Becton Dickinson) 등을 비교하였으며 그 결과 CD34^(+) 세포의 농도는 다음과 같았다. 1) 0.473±0.345, (%Mean±SD, N=70) 2) 0.663±0.519, (N=20), 3) 0.543±0.381 (N=46), 4) 0.624±0.341, (N=32). 시료로는 여의도 성모병원 카톨릭 조혈모세포이식 센터에서 채혈한 골수를 이용하였다. Four different methods for flow cytometric quantitation of CD34+ cell were compared using bone marrow samples (n=168). Following combination of antibodies were used for the analysis : A) CD45-FITC/CD34-PE (n=70), B) CD14-FITC/CD34-PE (n=20), C) CD14-FITC /CD34-PE /CD45-PerCP(n=46), D) DNA dye/CD34-PE/CD45-PerCP (n=32). Each method showed no significant differences among them (P=0.126, ANOVA test, SPSS Version 7.5). When we compare these methods using same samples (n=12), the P value became 0.832. The mean % of CD34+ cells calculated in this experiment were A) 0.474%, B) 0.663%, C) 0.548%, D) 0.624% respectively. In our laboratory, we decided to use CD45-FITC/CD34-PE methods as a routine protocol.

This study was carried out to improve the organic farming system about crop cultivation, compost production and application, plant diseases & pest control, weed control and marketing system of organic farming products to the case study in Chungnam Hongdong area. Agricultural technologies concerning pest & diseases control, weed control and compost production are not established due to lacks of systemized researches by the agricultural scientist, and agricultural machines profitable to this works had not developed yet. In cropping system, reasonable crop rotation had not conducted. The related cultivation of vegetables on the same ground for a long time cause a various plant disease easily. So crop rotation is a reasonable method about soil nutrient utility and soil disease control. It is a good method that introduce the barley and wheat in this field crop system. Those crop have a long root, so can use the other nutrient against the vegetable. In organic farming products, the safety and quality of products by the National Agricultural Products Inspection Center had not inspected except rice, lettus and apple. Inspection is needed for the development of organic farming and mutual confidence between producer and consumer, because the mutual confidence is a major thing to sustain the organic farming. In products marketing, it is more need for the information of organic farming products. Nowaday most products are marketed in Seoul region, but it is not a good method. To search the consumer in near region is a good method for decrease the cost of conveyance and maintain the quality of products. The varieties of distribution structure of organic farming products are required. The products are sold to department store in large city and the prices are about 30% higher than normal products. But when those are supplied in near region, the prices of those are similar to normal products. Direct transactions in near regions is a good method for decrease the cost of conveyance and strength the mutual confidence between producer and consumer.

This study was planned to analyze amino acids in the septal nucleus of dorsal and ventral hippocampectomized rats by high performance liquid chromatography (HPLC). Male albino rats were used. Under chloral hydrate anesthesia (20%, 2 ml/kg body weight), a hole was made in each parietal bone about 4 mm lateral to the sagittal suture, and 4 mm rostral to the lambda suture. The cortical tissue on each side was removed and, through this opening, the hippocampal tissue anterodorsal and posteroventral to the hippocampal flexures on both sides was removed by aspiration. This preparation served as the dorsal and the ventral hippocampal animals, respectively. The cortical control animal received the same surgery short of hippocampectomy. The normal rats served as normal control animal. One day later, the animals were sacrificed by decapitation in the cold room. Two to three milligrams of tissue was obtained form the septal nucleus in one side of the brain. The tissue samples were homogenized and centrifuged. Then content of each amino acid was measured by HPLC form the brain tissue. The contents of aspartate and glutamate were decreased significantly more in the dorsal and ventral hippocampal groups than in the normal and the cortical control groups. The contents of glutamate were decreased significantly more in the ventral hippocampal group than in the dorsal hippocampal, while there were no significant differences between the two control groups. It is inferred form the above mentioned results that glutamate and aspartate may be used as excitatory transmitters in septal nucleus, and that the dorsal hippocampus may be facilitatory to the septal nucleus, but the ventral hippocampus would be inhibitory/facilitatory to the cortex.
