甲壳

Results: The infected penaeid shrimps showed a rapid reduction in food consumption, lethargy, a pink to reddish-brown coloration and a loose carapace with white spots in succession, followed by ultimate death. The characteristic features of moribund shrimps were empty stomach, a pink to reddish-brown coloration, white spots on a loose carapace and swollen cephalothorax. The relative content of WSSV DNA in blood increased rapidly after the infected shrimp showed its first symptom of detestation of food.

结果：斑节对虾感染白斑症病毒后，依次表现出厌食、不活动、体色变红、甲壳出现白斑、反应迟钝直至侧卧死亡；濒死对虾的典型症状为空胃、红体、甲壳白斑、甲壳下水肿及甲壳易剥离；感染对虾出现拒食后，其血液中白斑症病毒 DNA的相对含量急剧增加。

The Journal of Crustacean Biology, published quarterly, contains papers of broad interest dealing with any aspect of crustacean biology, notices of business transacted at meetings of The Crustacean Society, book reviews of works on Crustacea, and pertinent announcements.

Locksley believes that AMCase, comparable to the chitinolytic enzyme found in marine and soil bacteria—and likely conserved in human evolution—attenuates the chitin-induced innate immune response by degrading the chitin.

洛克斯利相信AMCase比得上在海洋和土壤细菌中发现的甲壳素消化酶－并且可能在人类进化中保存下来了－通过降解甲壳素减弱了甲壳素诱导的先天性免疫反应。

Chintin used to produce thin films of material abundance in nature, there are quite a few Insecta or crustaceans of the shell is made by chintin ——— a non-crystalline polycarbohydrates, its chemical composition is celluiose, and chintin cellulytic, is the production of films by main ingredient.

用来生产甲壳薄膜的原料非常丰富，在自然界，有相当一部分昆虫纲或甲壳纲动物的外壳，是由甲壳质———一种非晶质多聚糖构成，它的主要化学成分是纤维素，而纤维素，正是生产甲壳薄膜的主要原料。

在相同条件下，比较不同脱乙酰度甲壳胺及N－取代甲壳胺的接枝聚合反应结果，表明：甲壳胺中氨基参与了接枝聚合反应的引发过程。

The comparison of the reactional results of different degree of deacetylation chitosan with those of N-substitute chitosan under the same reactional condition has demonstrated that the amino groups of chitosan took part in the initiation process.

Chintin with chintin film processing is not complicated, first of all the industrial processing of accumulation of crab and shrimp when chintin inmnersion hydrochloride, and a strong base to calcium and protein deposits, you can be assured of semi-finished chintin powder; and then add the acetic acid powder soluble in chintin erjia polyamlnes vlproic bisprone nitrogen and licl mixture, mixed solution evenly onto a glass plate, and lixiviating propylalcohol solution would reflect on the glass panes for the transparent on the film.

用甲壳质加工甲壳薄膜的工艺并不复杂，首先将工业加工蟹虾时积聚的甲壳质用盐酸浸泡，再用强碱使钙和蛋白质沉淀，就可得到半成品的甲壳粉末；然后将甲壳粉末溶于醋酸二甲胺、氮戊环酮和氯化锂混合液中，再将混合溶液均匀地洒在玻璃板上，并在异丙醇溶液中浸一下，玻璃板上便形成了透明的甲壳薄膜。

The results suggested that chitinhad a good solubility in the new solvent when its at -30℃and below, but the solubilityof chitin no longer increasesd notable as the temperature reduced; The joined of urea, incertain degree, strengthened the solvency of alkali solvent to chitin. When theconcentration of sodium hydroxide is 8%～12%, Chitin had a good solubility, and theapparent viscosity of chitin solution could up to 4000 mpa·s～5000mpa·s at roomtemperature; In addition,the solubility of chitin in new solvent was high when therefrigerated time was three days and above, but the refrigerated time could not too long,otherwise, the deacetylize degree of chitin got more bigger. The properties of chitin solution were tested by revolving viscosimeter, FT-IR,X-RD and so on.

结果表明，在-30℃及以下甲壳素能很好的溶解于新溶剂中，但甲壳素的溶解度不再随温度的下降而有所增大，而是基本保持不变；尿素的加入，在一定程度上强化了强碱溶剂对甲壳素的溶解，当新溶剂中NaOH浓度为8％～12％时，甲壳素在试验温度下可以获得较好的溶解度，所得溶液在室温下的表观黏度达4000 mpa·s～5000mp·s；冷冻时间为3 d及以上时，有利于甲壳素的溶解，超过3 d，甲壳素的溶解度变化不大，另外，冷冻条件下，甲壳素在强碱溶剂中仍会发生脱乙酰化反应，冷冻时间不宜太长。
