牙髓炎

(1) The 2% glutaraldehyole pulpotomy has the function of killing bacteria and could cure deep caries and early pulpitis;(2) The curative effects of six months after operation is better than that of three months and of upper jaw is better than that of lower jaw by using 2% glutaraldehyole pulpotomy;(3) The prognosis of 2% glutaraldehyole pulpotomy depends on selecting indication and the patients cooperation in the course of operation;(4) It must be early performed with the root canal therapy that the cases of further developing apicitis, the absorption of root apiex is over 1/3, the pulp necrosis and periapical disease.

(1) 2%戊二醛活髓切断术具有杀菌的功能，对于深龋及早期牙髓炎可以治愈；(2) 2%戊二醛活髓切断术治疗乳磨牙牙髓炎六个月后的疗效明显好于三个月的疗效，上颌组疗效明显好于下颌组；(3) 2%戊二醛活髓切断术的预后取决于适应证的选择及治疗过程中患儿的配合程度；(4)对于进一步发展为根尖炎的病例及根尖吸收超过1/3、牙髓坏死和根尖周有病变者，应及早行根管治疗术。

Motheds: to select 336 lomars with pulposis or apicitis from the aged and to devide them into two groups. in group the control group,the illed teeth were given only the root canal therapy. in group the experimental group, according to the difference of every root canal, the unobstructed root canals were treated by root canal therapy. while the obstructed ones were given the root canal resinifying, use two kinds of therapy method together to molais' pathological changes.then their curative effects were observed after two year.

选取336例中老年人患有不可复性牙髓炎、牙髓坏死、牙髓钙化、牙内吸收和急、慢性根尖周炎的患牙358颗，随机分为对照组和实验组，对对照组行常规根管治疗，对实验组则根据每个牙齿各根管的不同情况，采用根管-塑化联合治疗，观察2年进行临床评价。

2The distribution of HIF-1 a and COX-2 was unequal;.(3)These findings indicate that HIF-1a and COX-2 may be two important factors in pulpal lesions and there is a significantly hypoxia condiction in inflamed pulp .(4)The increase of HIF-1 a is a possible mechanism for hypoxia preconditioning .(5)Our results suggested that pulpal fibroblasts as well as macrophages might be involved in the pathogenesis of irreversible pulpitis.

和COX一2的表达均有不同程度的变化，在牙髓炎病程中可能发挥着重要的生理和病理作用，③在牙髓炎进程中和牙髓自身修复过程中存在着缺氧环境和缺氧耐受机制，④牙髓成纤维细胞有可能与单核巨噬细胞一同参与牙髓炎的病理进程，且具有修复和免疫功能。

Aims: To establish a model of rat endotoxic pulpitis.

目的：建立大鼠实验性牙髓炎模型；原位观察大鼠正常牙髓和炎症牙髓中Bcl-2和Bax的表达情况，探讨两者在牙髓炎病理变化中的作用。

Aim:To assess the role of Interleukin-1 receptor antagonist(IL-1ra) in the pulpal inflammation.

目的：了解正常人牙髓组织及炎性牙髓组织中白细胞介素1受体拮抗剂(IL-1ra)的表达，探讨它在牙髓组织正常防御和内毒素性牙髓炎中的作用机制。

Apoptosis are found in rat normal and inflammatory dental pulp, and it may have a important role in pulpitis.

正常牙髓和炎症牙髓中存在细胞凋亡，细胞凋亡在牙髓炎的转归和预后方面可能有一定的作用。

Expression of ET-1 in pulpitis was stronger than that of normal pulp.

结论与正常牙髓组织相比，炎症牙髓组织中内皮素-1表达增强，提示内皮素-1在牙髓炎发展过程中起一定作用。

Methods: Model of experimental rat pulpitis was established and ICAM-1 expression of normal dental pulp, pulpitis of immediate group,1 day ,3 days, 5 days, 7 days was analyzed by using immunohistochemical and image analysis technique.

建立大鼠实验性牙髓炎模型，用免疫组化法及图像分析技术检测正常牙髓、牙髓炎即刻组、1天组、3天组、5天组、7天组中ICAM-1的表达情况。

Methods: We established an experimental model of rat molars pulpitis, used homemade Calcium hydroxide compound as pulp-cap in pulpotomy of rats' teeth, Calvital and blank were det as the control groups. Forty rats' teeth in each group were observed using light microscope 4 and 12 weeks after pulpotomy.

建立大鼠早期牙髓炎的模型，应用自制氢氧化钙复合制剂作为鼠牙牙髓切断术的盖髓剂，以calvital作对照组及无盖髓剂作为空白对照组。

67 of old person latent to split tooth carry on clinical diagnosis, adopt the complex treatment method according to different situations to 63. 4 shallow form latent to split tooth, dental pulp normal having subjective symptoms to be only competent to transfer tooth treat jointly; Have deeper crackle as to 5, the vigor of dental pulp is normal, but there is trouble tooth of dentine irritated symptom, prepares against the hole, is filled with on the crack while adjusting the tooth contract; Pulpitis, 22 58 drops of trouble tooth with the sharp disease, symptom of the root already appear to 36, go ahead of the rest steel wire ring pitch or make, bring ring bonding in order to protect corona, rub except that high sharp abrupt slope, after dispelling the tooth and shutting the wound, the root canal with complete regeneration, observe for 2 weeks, after there is no clinical symptom, preceded and repair completely in time.

对63例老年人67颗隐裂牙进行临床诊断，并根据不同情况采用了综合治疗的方法。4颗浅表的隐裂牙，牙髓正常且无自觉症状仅行调牙合治疗；对于5颗有较深裂纹，牙髓活力正常，但有牙本质过敏症状的患牙，调牙合同时在裂隙处备洞、充填；对36颗已出现牙髓炎、22颗伴有根尖病症状的58颗患牙，先行钢丝环扎或做带环粘结以保护牙冠，磨除高尖陡坡，消除牙合创伤后，再行完善的根管治疗，观察2周，无临床症状后，及时做全冠修复。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
