The introduction combines traditional Chinese and Western medicine below the experience of enteritis of noxiousness of fine ailment of remedial Tibet mastiff, in order to offer reference. 1 hair sick condition and clinical expression ill dog are 2~4 month more age young dog, majority is come on suddenly, anorexia or abandon absolutely, mental depressed, systemic symptom worsens quickly, produce acuteness sex vomiting and diarrhoea, puke is first feed rotten, afterwards is yellow or olive bubble mucus and hematic type thing, have diarrhoea dung has the sticky stiff thing of grey yellow, turn after for rare dung of effluvial shape of embedded mucous membrane, then shows hematic dysentery, because ill dog is acuteness vomiting and diarrhoea are rapid dehydration, eyeball cave in, temperature is shown two-way and calorific,℃ of the 40~41 at the beginning of disease, 1~2d falls it is normal to come, after 3~4d answer elevatory, die very quickly next, 4~5d of course of diseases, the temperature when on one's deathbed drops more to normal temperature the following. Bottom of stomach of dog of die in one's bed of 2 analyse check has haemorrhage sex inflammation, show cardinal, small intestine mucous membrane falls off, alvine wall attenuates, there is gules mucus inside, mix inside large intestine have show wine blood excrement and urine, there are a lot of haemorrhage places on mucous membrane, haemorrhage of rectum mucous membrane is more, mesentery lymph node enlargement, sometimes afterwards sends intussusception, alvine tangent plane bleeds, cardiac muscle is loose, color becomes weak, cystic plentiful, liver is qualitative fragile and brittle. 3 diagnose 3.1 epidemiology to diagnose this ill much hair at young dog, rather dog of epidemic disease have an inoculation feels the most easily, be affected directly or affect secondhand, basically pass enteron infection, this disease all can happen all the year round, but with cold...

下面介绍中西医结合治疗藏獒细小病毒性肠炎的心得，以供参考。1发病情况和临床表现病犬多为2~4月龄幼犬，多数为忽然发病，食欲减退或废绝，精神沉郁，全身症状急剧恶化，发生剧烈性呕吐和腹泻，呕吐物先为食糜，继为黄色或黄绿色泡沫黏液和血样物，泻粪有灰黄色的黏稠物，后转为恶臭的内含黏膜状稀粪，继而呈血痢，由于病犬剧烈呕吐和腹泻迅速脱水，眼球下陷，体温呈双向发热，病初40~41℃，1~2d降至正常，3~4d后又复升高，然后很快死亡，病程4~5d，临死时体温多下降至常温以下。2剖检病死犬胃底部有出血性炎症，呈深红色，小肠黏膜脱落，肠壁变薄，内有红色黏液，大肠内混有呈暗红色血液粪便，黏膜上有许多出血点，直肠黏膜出血较多，肠系膜淋巴结肿大，有时继发肠套叠，肠切面出血，心肌松软，颜色变淡，胆囊充盈，肝质脆而易碎。3诊断3.1流行病学诊断本病多发于幼犬，未免疫接种犬最易感，直接感染或间接感染，主要通过消化道感染，该病一年四季均可发生，但以寒。。。

The Middle Proterozoic Caiziyuan peridotite was formed in the epicontinental basin at the ocean-land boundary or within-continent rift basin. Its mantle source could be metasomatized by the dehydration fluid of subducted plate, and much initial radioactive 〓Nd was added to the source.

中元古代菜子园橄榄岩形成于洋陆交界的陆缘盆地或与大洋相连的陆内裂陷盆地，其源区可能受到俯冲板块脱水流体的交代作用，有大量初始放射性〓Nd加入。

Thiol groups were good to be used in functionalizing gold nanoparticles, and ester bond formation and breakage played the major role in this research. Thioctic acid and 11-mercapto-1-undecanol were used to functionalize the gold nanoparticles and form ester bond by using the carboxylic acid group on thioctic acid and the hydroxyl group on 11-mercapto-1-undecanol. Concentrated sulfuric acid was used to be the catalyst in this reaction, and sodium hydroxide was added for the proceeding of the reverse reaction.

(1)PAL is better entrapped by PAG with a T∶C ratio of 8∶30.(2)PAL immobilized by glutaric dialdehyde on Bio-Gel P-300 is better than by CDC.(3)The best one is the dehydration and redehydration method.(4)Immobilized and permeated PAL active yeast cells are resistant to trypsin digestion and retain its PAL activity.

(1)固定化酶活性采用T∶C比为8∶30明显高于8∶19；(2)以戊二醛将PAL固定于Bio-GelP300优于用DCD固定化的酶；(3)质脂体包被中以脱水再加水法对酶活性影响较少，脂类组成以磷脂酰胆碱：胆固醇：磷脂酰丝氨酸比值7∶2∶1最好；(4)固定化PAL活性酵母细胞能较好地抵抗人工肠液中胰蛋白酶的水解作用，亦能明显降低苯丙氨酸的浓度。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
