Results: Remarkable pathological changes were found in h ippocampus: Nissl bodies decreased or disappeared, cyton swelled. The water cont ents and the level of LDH and NO were increased in scalded rats. CNTF could rema rkably improve the pathological changes and reduce the increase of LDH, NO a nd the water contents.

结果：大鼠严重烫伤后，脑组织含水量增加，海马出现怎么明显的病理变化，尼氏小体减少或消失，胞体肿胀，LDH和NO的含量增加；给予CNTF后，脑水肿、海马的病理变化有明显改善，并能降低 LDH和NO的含量。

The pathological changes, the conten ts of brain water, the contents of LDH and NO in hippocampus were observed in th e rats. Results: Remarkable pathological changes were found in h ippocampus: Nissl bodies decreased or disappeared, cyton swelled.

SD大鼠侧脑室埋管，制成30％体表面积Ⅲ度烫伤模型，伤后3 d，测定脑组织含水量，海马乳酸脱氢酶和一氧化氮的含量，做病理切片，尼氏染色。

Changes in Xc for different pulp cellulose fibers are not the same during the ultrasonic treatment. Crystallization and decrystallization may both exist during the treatment at the conditions of lower-intensity ultrasonic wave. After treatment with ultrasonic Xc of MBKP cellulose is decreased and that of EBKP is increased. The changes of Xc of different pulp cellulose are more closely correlated to the fibers' morphology size and the cavitation state. The maximum Xc of 84% is obtained when BEKP cellulose is treated under the conditions of ultrasonic frequency f=23-25kHz, power=400w, and treatment time t=720s.

不同原料来源的纤维素纤维，由于形态尺寸和超分子结构的差异，经超声波处理后超分子结构表现出不同的变化规律；超声波处理过程中，结晶和消晶两种作用同时存在；超声波功率对纤维素的结晶度有较大的影响，对晶体尺寸有一定程度的影响，但结晶度Xc与超声功率没有线性关系；在频率为23-25kHz，功率为400W条件下，对桉木漂白浆纤维进行超声波处理，可获得高结晶度（84%）的纤维素样品。

Staining and observing shows that the most pathological changes were interstitial pneumonia and hemorrhagic pneumonia, typical nonsuppurative encephalitis, and neurogangliitis et al. The lymphoid tissue was necrosis, and the amount of lymphocytes was reduced. The pathological changes of the positive cells, especially the epithelial cells were swell, denaturization and hyperplasy to the extent.

H.E。染色观察显示，病理组织学变化主要表现为间质性肺炎和出血性肺炎、典型的非化脓性脑炎、神经节炎等；淋巴结、扁桃体和脾脏等组织内淋巴细胞坏死、数目减少；有阳性反应的细胞，特别是阳性上皮细胞呈现不同程度的肿胀、变性、增生等病理变化。

CT demonstrates to better effect the osseous changes with a more accurate estimation of both diploic space widening and paranasal sinus changes.

CT在评价板障的增宽和副鼻窦的气化方面更加准确。

In PsNPV infected treatment, the color of the gland was purple-black dyed with eosin and the cells were distortedly squeezed together. The tracheae nearby showed grievous pathological changes and a lot of white granules deposited around it. The pathological changes in PsGV infected treatment showed another pattern. The gland body was relative small with smaller individual cells, most of which were red dyed with eosin. The cell limits were obscure.In coinfected treatment,there were few gland cells colorated by esoin.

结果表明，不同感染组粘虫前胸腺腺体都有不同程度的组织病变，PsNPV感染组在感染晚期与前胸腺相连的气管严重病变，出现大量白色颗粒状物累积，被伊红染成紫黑色，腺体细胞被挤压变形；PsGV感染组的前胸腺腺体变小，单个细胞也小，细胞界限不十分明显；两种病毒混合感染组的腺体细胞小，能被伊红染色的细胞极少。

In this case, enterprise's life cycle, especially the life cycles of Chinese enterprises becomes a very important subject for research Through the study on " book of changes ", we find that the divinatory symbol order of 64 divinatory symbols and its philosophy thought have contained various kinds of key elements in enterprise's behavior in book of changes.

这种情况下，对于企业生命周期的研究，尤其是对中国企业的生命周期研究是一项非常重要的研究课题。

The results suggest that there are significant fatty acid and amino acid metabolism changes in NASH. Excessive fatty acids accumulation in hepatic cells、ω-6/ω-3 ratio imbalance, dodecanoic acid decreased, and some amino acids contents changes are related to hepatic inflammation and injury.

结果提示NASH大鼠肝组织存在明显的脂肪酸谱和氨基酸谱变化，肝细胞内各类脂肪酸聚积、ω-6：ω-3PUFAs比率失衡、正十二烷酸降低以及某些氨基酸含量变化等可能对脂肪肝炎症发生、肝损伤有重要作用。

Everything else up the food web is going to be impacted," said oceanographer Scott Doney,"What's worrisome is that small changes that happen in the bottom of the food web can have dramatic changes to certain species at higher spots on the food chain, Doney said.

另一位海洋学家斯科特说，&任何海洋食物链上的生物都会受到影响，可怕的是，食物链底端任何微小的变化都会对食物链高端的物种产生重大影响。&

Objectives A rat model sciatic nerve crush injury was reproduced in rat, and behavioral changes, pain threshold, thermal withdrawal latency and the changes in c-fos expression in cornu dorsale medullae spinalis were examined, and the relationship between peripheral nerve regeneration and hyperpathia was explored.
