And their CD4+CD25+ Tregs in PB and MLN were much more than the model control group at the end of one or two weeks after treating with SASP and CLYSTER No. 1. Conclusion: CD4+CD25+ Tregs with strong immune suppression could play a central role in the initiation and development of mouse experiment colitis, and the CLYSTER No. 1 might exert its therapeutic effects on UC by the regulation of number and function of CD4+CD25+ Tregs.

Autoimmunity hypothesis of schizophrenia figures schizophrene has a certain degree of immunological functional disturbance,Hypothalmu- pituitary- adrenal axis can produceimmunosuppression. Hydrocortisone,the production of HPA axis,serve as important medium of immunosuppression, so we presume that hydrocortisone possibly induce immunological dysfunction of schizophrene.

精神分裂症的自身免疫假说认为精神分裂症患者存在一定程度的免疫功能低下，而下丘脑-垂体-肾上腺轴功能紊乱被认为是引起免疫抑制作用的主要机制之一，其中皮质醇是免疫抑制作用的重要介质，因此我们推测精神分裂症患者可能存在有皮质醇含量增高有关。

objective to isolate and purify the antimicrobial peptides with anti-toxoplasma gondii activity isolated from the haemlymph of musca domestica larvae.methods the antimicrobial peptides of musca domestica larvae were induced by infection and injury were isolated and purified by trituration,centrifugalization and column chromatography.then the antimicrobial peptides with anti-toxoplasma activity were sieved by mtt colorimetric method and haemacytometry.results it was found that two antimicrobial peptides had anti-toxoplasma activity through resource s cationic column chromatography and superdex g75 gel column chromatography.conclusion the two antimicrobial peptides with anti-toxoplasma activity existing in the haemlymph of musca domestica larvae had different anti-toxoplasma effect.

作者单位：山西医科大学寄生虫教研室，太原 030001；化学生物学与分子工程教育部重点实验室山西大学生物技术研究所目的从家蝇幼虫血淋巴中分离纯化具有抗弓形虫作用的抗菌肽。方法通过损伤加感染的方法诱导家蝇幼虫大量表达抗菌肽，然后经过研磨、离心和层析等过程，将家蝇幼虫抗菌肽进行分离纯化，采用四甲基偶氮噻唑蓝比色法和血细胞计数法筛选对弓形虫速殖子有抑制作用的抗菌肽。结果经resource s阳离子柱和superdex g75凝胶柱层析后，筛选出2种对弓形虫速殖子有杀伤作用的抗菌肽。结论家蝇幼虫血淋巴中存在抗弓形虫作用的抗菌肽，而且不止一种，但其效果有所不同。

The trypsin inhibitor is a kind of substance that can inhibit trypsin activity.

胰蛋白酶抑制剂是对胰蛋白酶具有抑制作用的一类物质。

The purpose of this study is to screen microorganisms with growth inhibition against plant fungal pathogens. The plate-dilution method was used to isolate the bacteria from salt marshes at Dafeng, Jiangsu. The antifungal activity of the bacterial broth filtrates against 5 phytopathogens was determined using mycelial disk method. The antifungal compositions of four active bacteria were analyzed primarily with chromatography techniques. Two hundred and thirty-five aerobic (92) and anaerobic (143) bacterial strains have been isolated from the coast salt marsh and sixty-five strains, of which 39 are aerobic and 26 are anaerobic showed greater than 30% of inhibition rate against the growth of at least one of the phytopathogenic fungi on petri dish.

为了开发对植物病原真菌生长有抑制作用的药源微生物，本实验采用平板稀释法从江苏大丰盐沼湿地土壤中分离微生物，并通过菌丝块法检测这些微生物代谢产物对5种植物病原真菌生长的抑制活性，进而利用柱层析分析其活性成分；结果共分离得到235株细菌，其中好氧细菌92株，厌氧细菌143株；体外活性测试结果显示有65株至少对1种测试植物病原真菌的抑制率在30%以上，其中好氧菌39株，厌氧菌26株。

Methods Spectrophotometry was used to study the activity of PLAP in the presence and absence of L Leu. PLAP relative activity was calculated according to the absorbance variation.

方法应用分光光度法分别测定有L－Leu和无L－Leu存在下的酶活力，根据其活力变化求出酶的相对活力；用双倒数作图法，确定L－Leu对PLAP的抑制类型并求出其抑制常数；同时也观察了pH对抑制作用的影响。

It was showed by synchronal fluorescence technique that AZP and 6-MP had effect on the conformation of BSA.

二者免疫抑制作用的机理相同，口服进入人体后，具有嘌呤拮抗作用。

On the basis of these theoretic methods, there are three different research conclusions to the problem mentioned above. The first one is the stimulative view, the second is the suppressive view and the third one is the unconspicuous view or the view that both effects existed.

在这些理论方法基础上，关于FDI与中国企业科技进步关系的问题，目前主要有三种不同的研究结论：一是发现有促进作用的研究结论；二是发现有抑制作用的研究结果；三是发现作用不明显或两方面作用都有的研究结论。

MNSFP was a previously identified novel implantation-related factor that needed to be further investigated in our lab, and is a lymphokine produced by suppressor T cell.

MNSFD是本实验室正在研究的另一个新发现的着床相关因子，它是一种由抑制性T细胞合成的具有非特异性免疫抑制作用的淋巴因子，因其能抑制IL-4的分泌和Th2细胞的产生，所以推测其可能与母胎间免疫耐受的形成有关，但有待于研究证实。
