벼-자운영의 연속재배체계 확립을 통해 자운영을 지속적으로 이용하고자 기계이앙 및 직파 파종시기와 재배양식을 달리하여 시험한 결과는 다음과 같다. 1. 자운영의 식물체 무기성분함량은 T-N이 2.92%, P2 O5가 0.74%, K2 O가 4.28%로 ㏊당 30 ton정도의 녹비가 생산되면 벼 재배시 인산을 제외하고는 표준시비량 이상에 해당되었다. 2. 자운영 녹비의 포장 잔존율은 초기 1주일 이내에 급격히 떨어져 토양에 환원되었고, 무기성분의 잔존율도 같은 경향이었다. 질소성분에 비해 인산과 가리성분의 환원정도가 더 빨랐고, 심토에 비해 표토에서 낮은 결과를 보였다. 3. 무경운 직파재배에서는 5월 25일 이후 파종할 경우 파종 시기에 관계없이 벼 수확후 자연적인 자운영 재입모로 다음해 피복이 가능하였다. 4. 무경운이앙은 자운영의 지상부 예취 없이는 벼 이앙이 불가능하여 농가활용이 곤란하였고, 경운이앙은 5월 25일 이앙시 벼 수확후 자운영의 자연적인 입모가 극히 불량한 반면, 6월 4일 경운후 이앙시 벼의 충분한 생육과 수량이 확보되고 운영의 자연적인 재입모로 다음해에도 자운영 조성이 가능하였다. 5. 자운영포장에 벼 이앙시 결주율은 경운에 비해 무경운에서 높았고 이앙심도도 무경운이앙시 예취된 자운성 때문에 얕아 도복이 우려되었다. 6. 자운영 후작 포장의 벼 수량은 무경운직파의 경우 입모가 불량하여 수량이 낮았으나, 경운이앙의 경우 자운생이 재배되지 않은 대조구에 비해 4~6% 증수되었다. Chinese milkvetch (Astragalus sinicus L.) has been traditionally used as a green manure supplying mineral N and organic matters to soil. In rice-Chinese milkvetch interrelay cropping system, three rice cultivating methods (no-till direct seeding, no-till transplanting, and tillage transplanting) were evaluated for stand reestablishment without reseeding Chinese milkvetch with two cropping times (May 25 and June 4) for two years. Chinese milkvetch incorporated was decomposed rapidly in the first week. Decomposition was fast in topsoil than in subsoil. Natural milkvetch reestablishment (NMR), following harvest of no-till-direct-sown rice was good enough to cover the paddy field in both cropping times, but rice yield of this method was lower than that of transplanted rice on paddy field without milkvetch cultivation. Even though good NMR was secured in no-till rice transplanting, the shoot of milkvetch should be removed before machine-transplanting of rice seedlings. NMR was better in rice cropping at the mid-ripening stage of milkvetch (June 4) than at the late-bloom stage (May 25). Rice yield was higher in tillage transplanting at the mid-ripening stage of milkvetch (June 4) than in the other rice cropping method.

Objectives: This study investigates the mechanism of Hwanggeum-tang (HGT) and Gamchosasim-tang (GST) on inflammatory bowel disease (IBD). Methods: The mice (C57BL/6N) were treated with distilled water and 3% dextran sulfate sodium (DSS) to experimentally induce ulcerative colitis. The mice were divided into 7 groups of (6 mice: normal, negative control, positive control (with sulfasalazine), 4 experimental groups (with HGT and GST, respectively). RAW 264.7 cells were used for cell experiments. The experiment was conducted in two ways: in vitro and in vivo. Results: In the experimental group (HGT, GST) of in vitro experiments, NO production decreased, and significant changes in gene expression and protein activation were observed. The length of the colon recovered in the experimental groups (HGT, GST) of the in vivo experiment was longer than that of the negative control group, and the mucosal barrier was recovered. Sone significant changes in the amount of mRNA expression were partially observed, and significant changes in protein activation also were confirmed. Conclusions: HGT and GST are effective in treating IBD caused by DSS. In the same herbal preparation group, the higher the concentration, the better the experimental effect, and when the same concentration was tested, HGT was more effective than GST. Herbal medicine has a higher antioxidant effect than sulfasalazine, so it is also excellent for cell protection.
