Straw returned to field played a positive role in increasing soil insect communities with the largest contribution, primarily the amounts of individuals and dominant species of macro and meso/micro soil animal, especially Neanuridae and Isotomidae animals individual amounts increased by nearly 10 times.(3) Soil nutrien had a positive correlation with soil bacteria, azotobacter, ammonifying bacteria, cellulose decomposing bacteria and denitrifying bacteria. Straw returned to field could stimulate effective microorganisms growth and population quantity in the soil. The increase of microbe community amount is 15%~44% more than that of CK.(4) Soil nutrien had a positive correlation with soil phosphatase, urease and sucrase activities, and a negative correlation with catalase.

Results: From the third to sixth month of gestation, some small NOS positive cells could be seen in the lamina propria mucosae. With the fetal age increased, the number of NOS positive cells increased too, and at the same time, the positive reaction of NOS increased gradually.

结果：第3~6个月龄时，胃粘膜固有层内皆可见胞体较小的NOS阳性细胞分布，随着胎龄的增加，NOS阳性细胞数目逐渐增多，染色逐步加深。

The histopathologic changes included lymphocyte and monocyte infiltration,hyperplasia of synovial cells and small vessels,interstitial fibrosis,hyaline degeneration and cartilaginous metaplasia.The immunohistochemical observations showed that the high expressions of IL-1 and IL-6 were significantly different between the pathologic plicae and the control groups（P＜0.01）.The positive expressions of IL-1 and IL-6 were the synovial cells and monocyt-lymph cells in the pathologic synovial plicae.The positive expressions of MMP-1 and TIMP-1 have significant difference between the experiment and control group（P＜0.01,P＜0.05）.The expression of MMP-1 was positive in synovial lining cell,monocyte,fibroblast,endothelial cell in small vessel and chondrocyte.The TIMP-1 expression was detected in the synovial lining cells and a small quantity fibroblast.

结果 正常滑膜皱襞和病理性滑膜皱襞在滑膜细胞增生及小血管增生、间质纤维化及玻璃样变、软骨化生组织学改变方面，差异均有显著性（P＜0.01）；IL-1、IL-6在病理性滑膜皱襞内的增生滑膜细胞、单核及淋巴细胞和在正常滑膜皱襞内的表达差异均有显著性（P＜0.01）； MMP-1、TIMP-1在病理性滑膜皱襞和正常皱襞内的阳性表达，差异具有显著性（P＜0.01，P＜0.05），MMP-1在增生滑膜衬里层细胞、单核和纤维母细胞、血管内皮细胞和软骨化生的软骨细胞呈阳性表达；TIMP-1只在滑膜衬里层细胞和少量纤维母细胞有表达。

Results Immunostaining of cNOS and iNOS were negative in the rectums of normal rabbits, whereas the results in the of rabbits infected with S. japonicum were strong positive. The positive immunostaining of cNOS was observed in mucosal capillaries and submucosal vessels. Besides in capillaries and submucosal vessels the positive immunostaining of iNOS was seen in schistosoma ova, ova granuloma, fibroconnective tissue and suppuratie cells.
