Results Both dosages of 153 Sm have an initial pro-i nflammatory effects during one week after injection,and then resulted in reducti on of joint diameter and skin surface temperature.153Sm (3.7×107 Bq) s howed a more alleviation than 153 Sm (1.85×107 Bq) in respect of macr oscopic and histologic changes.

注射153Sm(1.85×107Bq)导致一过性炎症反应，7 d后肿胀和局部发热缓解，并持续36 d.153Sm(3.7×107Bq)同样有一过性炎症反应，7 d后缓解，关节直径和皮肤温度较对侧关节有差异(P＜0.05)，并一直持续至处死前未改变。而大体形态学和病理学可见滑膜炎减轻，其指标与对侧相比差异有显著性(P＜0.05)。

At the same time,we found that the conversion rate decrease with the water content increase,lower conversion rate;it is in favor of high oleic acid content in the production of biodiesel, thus erucic acid have adverse effects.

同时还发现，水对该反应有抑制作用，随着其含量增加，转化率降低；油酸对该反应有促进作用，而芥酸有不利影响。

The molecular weight of dextransucrase measured by SDS-PAGE was 170 kDa ,which was similar to the enzyme from Leuconostoc mesenteroides. The enzyme had an optimum temperature between 25and 30℃ and an optimum pH of 5.4. It was relatively stable in the range of pH 5.0 to 7.0, but the stability declined rapidly as soon as the temperature rose over 35℃.

以蔗糖为底物，酶促反应的最适温度为25～30℃，最适pH值为5.4，动力学常数Km值为10.43 mmol/L；酶活在pH 5.0～8.0较为稳定，在室温（25℃）保藏4 天仍有59%的酶活力，4℃保存7周酶活力仅下降一半，但在35℃以上失活很快；Ca2+对催化作用有较大的促进，Mg2+有微弱的促进作用，K+对催化反应无影响，Cu2+的抑制作用最强。

The cytochemical localization of POD showed that the peroxidase was found in cells ofboth cultivars after inoculation. The activity of POD in resistant cultivar was higher than that innot only the uninoculated controls but also the inoculated susceptible ones and localized morewidely, such as localized in mesophyll cell wall, intercellular spaces, membranes of chloroplastand mitochondrion and vacuolar membrane. Whereas the POD in susceptible cultivar waslocalized mainly in cell walls but little in plasma membrane with a lower range and intensitythan that in resistant cultivar.

对过氧化物酶的细胞定位研究发现，无论抗病杨树还是感病杨树，接种后均发现细胞中有过氧化物酶反应产物，通过分析发现，毛白杨过氧化物酶的活性不仅明显高于未接种的对照，也明显高于接种处理后的北京杨，并且定位更广泛，在细胞壁、细胞间隙、叶绿体膜、线粒体膜及液泡膜上均有大量定位，而北京杨酶反应产物主要分布于细胞壁上，在细胞膜、核膜局部有少量定位，定位范围及强度均小于毛白杨。

In the second part, the cross-coupling reaction of organoboronic acid witharyl halide catalyzed by Pd has been studied, and the 〓 catalyzedcross-coupling reaction in organic phase and the 〓-TPPTS catalyzed reac-tion in water phase have been investigated also.
