活性碳

Results showed that:there were significant differences in the carbon to oxygen ratioamong various positions and processingconditions;lignin and abstracts mainly made up the surface of bamboo;high temperature drying resulted in the decomposition of volatile abstracts in the surface,whichindicated some structure of cellulose and hemicellulose,while the effects of processing with boracic acid were not apparent;the bamboo processed in hightemperature and with boracic acid showed decreasedfree hydroxide and activity at the same time;the amount of active free hydroxide of inner layer was higher thanthat of the outer.

结果表明：不同部位和不同处理条件下竹材表面的碳氧比有很大差异；竹材表面主要以木素和各种抽提物为主；高温干燥导致竹材表面易挥发的抽提物分解，使部分纤维素和半纤维素的结构特征得以显露，而硼酸处理效果不明显；高温处理和硼酸处理后竹材表面的自由羟基减少，活性降低；竹黄表面的活性自由羟基的数量高于竹青表面。

These results suggested that corm formation could be improved by MJ but suppressed by SHAM through regulating the LOX activity, resulting in carbohydrate accumulation and increase of antioxidant enzymes activities in Gladiolus hybridus .

以上试验结果说明SHAM对唐菖蒲试管结球起抑制作用，而MJ有明显的促进作用，可能通过外施MJ提高了LOX活性及内源MJ含量，调动碳水化合物的积累，增加抗氧化酶的活性，从而对球茎的发生和生长进行调控。

Soil microbial biomass and activities of invertase and urease all tended to decrease after pot-culture experiment, while the correlations between these biochemical properties and field ages were similar to those before this experiment, suggesting that rice cultivation without fertilization consumed part of soil microbial biomass, decreased soil enzyme activities correlated with C and N transformation, and affected soil nutrients status disadvantageously.

温室盆栽试验之后，水稻土的微生物生物量及酶活性与利用年限之间的关系规律和种植水稻之前基本一致，且整体上又趋于下降，即无施肥条件下种植水稻转化利用了土壤部分微生物生物量，并减弱了与碳氮转化相关酶的活性，对保持水稻土的营养水平造成不利影响。

Several inducers cicada exuviae, colloidal chitin, horsefly cuticle, shrimp, maggot and silkworm chrysalis were compared with their effects on production of cuticle-degrading protease of entomopathogenic fungus Metarhizium anisopliae.

研究了不同碳氮源对金龟子绿僵菌产生与分解昆虫外壳相关的蛋白酶活性和同工酶谱带的影响。结果表明：蝉蜕、虻虫壳、蝇蛆壳、蚕蛹壳、虾壳、胶体几丁质均可使金龟子绿僵菌产生蛋白酶，虾壳和胶体几丁质所产生的蛋白酶比活性最高，蝉蜕次之。

Investigations have already shown that HO can increase blood stream into uterus placenta, accelerate the formation of blood vessels, and protect placenta histiocyte. Enough blood stream into uterus placenta is the prerequisite for healthy growth of a fetus. Internal and external researches mainly focus on adults or

本研究通过检测健康足月儿及足月小于胎龄儿脐血中HO-1的活性，血浆碳氧血红蛋白的百分含量，并观察HO-1在脐血管上的表达，研究：⑴新生儿脐血中HO-1活性、HbCO百分含量及其与出生体重的关系；⑵新生儿脐
