兔眼角膜穿通伤后房水PGE2与总蛋白的变化

本文通过放免法与ＬＯｗｒｙ法测量了兔眼角膜穿通伤后房水ＰＧＥ２与总蛋白含量。结果：兔眼角膜穿通伤后１、３、８、２４、４８、７２小时房水ＰＧＥ２含量与正常值比较有非常显著性升高（Ｐ＜０．０１），到７天也未能降至正常（Ｐ＜０．０５）；伤后１．３、８．２４．４８小时房水ＴＰ含量与正常值比较有非常显著性升高（Ｐ＜０．０１），但７２小时后已降至正常（Ｐ＜０．０５）。我们认为：兔眼角膜穿通伤后ＰＧＥ２．ＴＰ含量显著性升高，ＰＧＥ２是ＢＡＢ破坏的重要的炎症介质，ＴＰ是ＢＡＢ破坏的结果。它们能代表损伤性炎症的严重程度。

延髓腹面降压区与肾血管阻抗的关系（Ⅰ）

实验用３００～３５０ｇ雄性Ｗｉｓｔａｒ大鼠，氨基甲酸乙酯腹腔麻醉。电刺激（０．２ｍｓ４０μＡ１００Ｈｚ８ｓ）并经兴奋性氨基酸Ｌ－谷氨酸（Ｌ－Ｇｌｕ）检测性验证，提示大鼠延髓尾端Ⅻ对脑神经丛第三支根部１ｍｍ×１ｍｍ区域为降压区（ｄｅｐｒｅｓｓｏｒａｒｅａｉｎｖｅｎｔｒａｌｓｕｒｆａｃｅｏｆｍｅｄｕｌｌａｏｂｌｏｎｇａｔａ，ＶＳＭｄ）。电刺激该区可见平均动脉血压（ＭＡＰ）以１６．９９的斜率下降，最大百分数为２６．８２±８．９３（Ｐ＜０．０１　。ｎ＝１０）．其下降率与刺激时间呈对数式关系。Ｌ－Ｇｌｕ微量注射后。在降压的同时心率（ＨＲ）减慢，分别为２．６７±０．４７ｋＰａ（Ｐ＜０．０１）和３０．３３±４．２３ｍｉｎ￣（－１）（Ｐ＜０．００１，ｎ＝６）。切断双侧迷走神经后降压和减心率反应减弱，分别为１．４６±０．４５ｋＰａ和５．６±４．８ｍｉｎ￣（－１）（Ｐ＜０．０１；ｎ＝５）；双侧损毁肾交感神经，基础ＭＡＰ下降，同时降压反应被削弱，为１．８１±０．４９ｋＰａ（Ｐ＜０．０１）但对减心率反应无影响（Ｐ＞０．０５，ｎ＝５）。

Value of D-Dimers in patients with acute aortic dissection

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P ＜ 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (＞0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P ＜0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P ＜ 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.     

Research of combined liver-kidney transplantation model in rats

Objective： To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods： SD rats served as both donors and recipients. 4℃ sodium lactate Ringer＇s was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava （IVC） inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results： Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion： This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.

The comparative studies of the influences of Urapidil and Nicardipine on sino-atrial node function, atrio-ventricular node function and hemodynamics

Objective:To investigate the influences of urapidil and nicardipine on rabbit sinus function,atrio-ventricular node function and hemodynamics.Methods:Thirty-two Angora's rabbits were selected and randomly divided into four groups.U1 group:urapidil 0.25 mg/kg;U2 group:urapidil 0.5 mg/kg;N1 group:nicardipine 10 μg/kg;N2 group:nicardipine 20 μg/kg.All these medicine were administrated within 30 seconds.Measurements were taken before and after the administration of urapidil or nicardipine for the following data:mean blood pressure(MAP),heart rate(HR),sino-atrial conduction time(SACT),maximal sinoatrial recovery time(SNRTmax)corrected sinus node recovery time(CSNRT),index of sinus node recovery time(SNRTI),Wenckebach A-V conduction frequency (WB),and P-R interval.Results:Significant MAP and HR changes were identified in all of the four groups before and after administration of both urapidil and nicardipine.No significant changes could be found in the rest of the parameters.Intergroup analysis showed that SACT and CSNRT of N1 and N2 groups were shorter than those of the U2 group(P＜0.01);the MAP decreased(P＜0.01)and the HR increased drastically(P＜0.01).Conclusions:Neither urapidil(0.25 mg/kg,0.5 mg/kg)nor nicardipine(10μg/kg,20μg/kg)has any significant influence on rabbit sinus function or rabbit atrio-ventricular node function.Nicardipine could be a better choice than urapidil for parafunctional sinus node patients.
