The treated group were hypodermically injected insulin 3U/d at interfemus for 4 months, white DC and NC group were vehicle groups that were treated with the same close saline, By using SABC method, thee express ion of collagen type Ⅰ and Ⅲ in SAN was detected.

Methods: Animals were randomly classified into 5 groups:gaster-poured by physiological solution; gaster-poured by ethanol; gaster-poured by ethanol after hypophrenic vagotomy; gaster-poured by ethanol after big-small splanchnicotomy; gaster-poured by ethanol after hypophrenic vagotomy and big-small splanchni-cotomy.

动物被随机分为5组，每组10只。A组：单纯生理盐水灌胃组；B组：单纯乙醇灌胃组；C组：膈下迷走神经切断乙醇灌胃组；D组：内脏大、小神经切断乙醇灌胃组；E组：膈下迷走神经和内脏大、小神经均切断乙醇灌胃组。

Methods: There were 65 patients with DN included in this sutdy on the unchanged treatment base of antidiabetic diet, hypoglycemic and hypotensor, PGE 1200ug was added into NS 250~500mL, drip intravenous once a day, continued for 21 days.

6 5例 DN患者在原有饮食控制、降血糖、降血压治疗不变的基础上，PGE1 2 0 0 μg加入生理盐水 2 5 0～ 5 0 0 m L 中静滴，每日 1次，连用 2 1天。

Objective To study the protection of spinal cord ischemic injury by means of regional infusion with hypothermic normal saline and adenosine.

目的 研究低温生理盐水和腺苷对兔主动脉阻断致脊髓缺血损伤的保护作用。

Methods. We describe our treatment, which inoles continuous irrigation using a saline infusion tube inserted into the infectious spondylitic disc as the primary lesion and insertion of a drainage tube into the iliopsoas abscess communicating with the primary lesion.

我们的方法包括将生理盐水通过输液管插入到感染化脓的椎间盘进行灌洗，将另一个输液管插入与化脓性逐渐盘相交通的髂腰肌脓肿病灶处进行引流。

The rats' infraorbital nervous tracts were exposed during test. 0.5% Adriamycin was directly injected into the axons, while normal saline into the opposite site as control.

本实验通过手术解剖暴露大鼠眶下神经束，用0.5%阿霉素直接神经干内注射，对侧用生理盐水注射作自身阴性对照。

Methods: We used pockets of water compres sing rabbit infrapatellar fat pad, the pressure in pockets of water remaining 33 0-340 mmHg, accompanied knee joint passive flexion and extension 2 hours every day, 7 days later, injected 0.9% NaCl 0.5ml on control and injury gruop, extra cted joint flushing fluid, and the fluids were measured by radiommunoassay.

应用水囊压迫兔膑下脂肪垫，水囊内压力保持330 ～340mmHg，配合膝关节被动屈伸运动，每天2h，压迫7d后，于对照组与损伤组注入0.5ml 生理盐水，抽取关节冲洗液，对观察指标进行放射免疫测定。
