We used Aeromonas hydrophila which we separated from the diseased Paralichthys olivaceus to made a inactivated whole cell bacterin .We injected this vaccine in the mice and the Paralichthys olivaceus .Both the mice and the Paralichthys olivaceus gained a good protection of 80% and 70%.The fish with dipping immersion gained a good protection of 85%,and the incidence of disease was 6%.We detected the antibody level in the antiserum by agglutination reaction and indirect ELISA which seemed to be immunogenic crucially.We anatomized the mice then we found that all the purtenance of the immunzied mice are healty.All of this proved that the vaccine is effective.

本实验将所分离到的嗜水气单胞菌用终浓度为0.2%~0.5%的甲醛对菌体进行灭活，制备了灭活疫苗，并优化灭活疫苗的灭活条件；将制备的灭活疫苗分别注射小鼠和牙鲆，均取得了较为理想的效果，其中小鼠的免疫保护率达到80%，牙鲆的免疫保护率达到70%；采用渗透压差法大规模浸泡免疫牙鲆也取得了很好的效果，浸泡免疫过的牙鲆发病率仅为6%，攻毒后免疫保护率为85%；通过应用间接ELISA方法检测受免动物的抗血清，并将牙鲆的抗血清注射新西兰白兔，从而获得兔抗鱼血清，更便于检测，结果都表明动物体内产生了较高的抗体水平；剖检攻毒后的动物，发现免疫过的动物内脏健康无异样，表明该疫苗安全有效，从而为防治牙鲆腹水症开辟了一条新途径，也为进一步制备其基因工程疫苗奠定了基础。

Through the study we could perorate that the DTI is one of the core ideologies of Yellow Emperor's Internal Classic's treatment theories. It has significant values to treatment and prevention of disease and possesses solid theory background and rich connotation. The DTI availed us to build up firm dynamic concept and not to regard health and disease quiescently and isolatedly. It has momentous meanings to decrease incidence rate and boost curative effect and deserves us studying further.

本文通过研究探讨，认为动态治疗思想是《黄帝内经》治疗理论的核心思想之一，具有坚实的理论基础和丰富的内涵，对于疾病的治疗和预防有着重要价值，有利于我们临床树立牢固的动态观，防止静止、孤立地看待健康和疾病，对于减少发病率、提高疗效具有重要意义，值得进一步深入研究。

objective:to study and analyze the features of lower limb fatigue fracture in the special force by means of radiodiag-nosis.methods:anterior-posterior and lateral films and clinical follow-ups were made to all the affected limbs in the56cases of lower limb fatigue fracture from june2003to feb.2006.results:through medical history and radiodiagnosis all the cases were giv-en definite diagnosis,achieved good treatment results and all had clinical follow-ups.the average length of clinical follow-ups was3months.following treatment,all patients returned to work and resumed training.conclusion:lower limb fatigue fracture finds a rather high incidence in the special force.special features could be seen in the x-ray film,which has obvious clinical significance in the differential diagnosis of other diseases.

摘要］ 目的：分析特种部队下肢疲劳骨折的x线特征性表现和鉴别诊断。方法：从2003年6月～2006年2月，对56例来院就诊治疗的下肢疲劳骨折的患者全部进行患肢x线正侧位片检查和随访。结果：本组病例依据病史和x线分析，均明确诊断，经治疗后效果好，全部获得随访，平均随访时间3个月；骨愈合时间1～2个月，全部恢复工作和训练。结论：下肢疲劳骨折在特种部队发病率高，x线片中具有特征性表现，与其他疾病的鉴别具有重要的临床意义。
