脑损伤急性期脑微血管5—羟色胺,多巴胺含量变化与外伤性脑水肿…

探讨脑损伤急性期脑微血管中５－羟色胺，多巴胺的含量变化其与外伤性脑水肿的关系。方法；采用高效液相色谱－电化学检测器，直接检测大鼠及脑损伤急性期微血管中５－ＨＴ，ＤＡ的含量。结果：脑损伤后０．５小时脑微血管中５－ＨＴ，ＤＡ含量明显增加，伤后６小时仍明显高于对照组，相关非常显著；同时限检测脑组织不含量明显增高。     

记忆合金环抱器在复杂骨折治疗中的应用

对于一些特殊类型骨折以及严重的粉碎性骨折，传统的内、外固定方式难以固定，或固定效果不确切，不利于早期功能锻炼，影响骨折的愈合。NiTi记忆合金是近年来应用于骨折固定的新型内固定材料，自1998～2003年我们采’用记忆合金环抱器治疗各种复杂骨折17例，取得了满意的疗效。

益母草防治初发期急性肾小管坏死的实验研究

ＳＤ成年雄性大鼠，禁止１６小时，肌注甘油引起急性肾小管坏死（ＡＴＮ），于其初发期给予不同药液，观察到益母草组３、２４及４８小时Ｂｃｒ升高值，２４及４８小时ＢＵＮ升高值均明显低于自来水组和单纯禁水组，而与校正对照异搏停组近似，肾组织损伤程度亦明显减轻。结果表明，益母草对初发期急性肾小管坏死（ＩＡＴＮ）有一定的防治作用。     

Effect of autocontrol micromotion intramedullary interlocking nail on fracture healing： an experimental study

Objective: To investigate the effect of autocontrol micromotion locking nail ( AMLN ) on experimental fracture healing and its mechanism. Methods: 16 goats undergoing both sides of transverse osteotomy of the femoral shafts were fixed intramedullary with AMLN and Gross-Kempf (GK) nail, respectively. The follow-up time was 7, 14, 28 and 56 days. Roentgenographic, biomechanical, histological, scanning electromicroscopic and biochemical analyses were done. Results: (1) The strength of anticompression, antiflexion and antitorsion in the fractural end in the AMLN-fixed group was higher than that of GK nail-fixed group; whereas, the rate of stress shelter in the fractured end decreased significantly (P<0.01). (2) The content of the total collagen, insoluble collagen, calcium and phosphate in the AMLN-fixed group was higher than that in the GK nail-fixed group (P<0.05). (3) Histological observation and quantitative analysis of calluses revealed that AMLN could promote the growth of bridge calluses and periosteum calluses. Hence the facture healing and remolding process achieved early, which was much better than traditional GK nail fixation. (P<0.05). (4) 7-14 days postoperation, the calluses of AMLN-fixed group was flourish and camellarly arranged and the collagen fibril formed constantly in the absorption lacuna of bone trabecula. 28-56 days postoperation, the collagen fibril was flourish around the absorption lacuna and was parallel to the bone's longitudinal axis. Active bony absorption and formation were seen, so was remolding and rebuilding. Haversian system was intact and the bony structural net was very tenacious because of the deposition of calcium salt. None of the above findings was observed in the GK nailfixed group. Conclusions: The design of AMLN accords well with the plastic fixation theory. As the geometry ametabolic system constituted by the intramedullary fixation instruments and the proximal and distal end of the fracture is very firm and stable, the disturbance to the physical stress distributed in the fractural end is light. The generation and conduct of the intermittent physical stress between the fractural parts could reach the balance between stress conduct and stress protection. The feature that the healing and remolding take place at the same time speeds up the fractural healing process.     

抗人生长激素免疫血清的制备和鉴定

Using small dosage of human growth hormone to immunize rabbit or guinea pig, it is able to induce anti-hGH antibody formation with high titre and high affinity that could be applied to hGH RIA. In the present study five rabbits and three guinea pigs were immunized with 125-200 micrograms and 250-285 micrograms per animal of hGH respectively, followed by boosters of 10-20 or 160-250 micrograms of hGH at 2-4 week intervals for 6 or 3 months. Blood was drown 1-2 weeks before each booster for determination of antibody formation. Antibody titre and affinity were successively observed and specificity of antibody was determined for the final bleeding. It was shown that titres of immune sera from guinea pigs were much higher than those of rabbit immune sera, but vice versa for antibody affinity. This might be due to larger immunogen dose used for guinea pigs than for rabbits. Fourteen different peptide hormones were tested in reference to cross-immunoreactivity to anti-hGH antibody. It could be demonstrated that the major cross-reactive hormones are hFSH and hLH, and hTSH also reacts to rabbit anti-hGH immune sera at a lesser degree. These cross reactivities are obviously owing to the molecular homogeneities between hGH and these hormones especially of their alpha-subunits.
