摘要
目的探讨盐酸戊乙奎醚对休克大鼠肾损伤的保护作用。方法健康SD大鼠24只,随机均分成3组。A组为休克常规治疗组,B组为盐酸戊乙奎醚低剂量治疗组(0.6mg/kg),C组为盐酸戊乙奎醚高剂量治疗组(2.0mg/kg)。B和C组在常规抗休克治疗的同时腹腔注射盐酸戊乙奎醚。实验中采用梯度放血期(40min)和血量调节期(20rain)的双阶段放血方式制作休克模型,3组均给予自体血复苏(20min)进行常规抗休克治疗。观察3组的肾功能的变化及肾脏超微结构改变。结果B组中尿素氮(BUN)、肌酐(SCr)、尿B2微球蛋白(J32H—MG)以及N.乙酰-β-氨基葡萄糖苷酶(NAG)分别为:(8.02±0.32)mmol/L、(103.21±8.13)μmol/L、(58.02±0.32)ng/ml、(63.21±5.13)mg/L,C组:(6.01±0.22)mmol/L、(95.21±5.04)μmol/L、(49.01±2.22)ng/ml、(44.80±3.72)mg/L,均明显低于A组[(23.23±0.51)mmol/L、(302.00±5.15)μmol/L、(83.23±0.51)ng/ml、(85.60±6.32)mg/L,P〈0.05],其中C组低于B组(P〈0.05)。透射电镜下观察B组和c组肾小管及肾小球的损伤均比A组轻,且C组的肾脏组织损伤程度更轻。结论盐酸戊乙奎醚具有促进休克大鼠肾功能恢复,减轻肾组织超微结构改变,从而减轻失血性休克大鼠肾组织损伤的作用,且2.0mg/kg作用更加显著。
Objective To investigate the protective effect of penehyclidine hydrochloride on renal injury in shock rats. Methods 24 healthy SD rats were randomly divided into 3 groups (A, B and C). Group A was shock and routine treatment group, group B was low penehyclidine hydrochloride dose (0. 6 mg/kg) group. And group C was high penehyclidine hydrochloride dose (2. 0 mg/kg) group. Hem- orrhage was performed by gradient volume - control phase (40 mins) combined with an adjustment phase (20 rains) to build the model, then we give autologous blood resuscitation (20 min) for anti shock treat- ment. The pathological changes of renal function and renal uhrastructure were observed. Results The dates of urea nitrogen (BUN), creatinine (SCr) and urine 62 micruglobulin ( [32H - MG) and N/beta/ acetyl glucosaminidase (NAG) are ( 8. 02 ± O. 32) mmol/L, ( 103.21 ± 8.13 ) μmol/L, ( 58.02 ± 0.32) ng/ml, (63.21 ±5.13) mg/L in group B; (6.01 ±0.22) retool/L, (95.21 ±5.04) μmol/L, (49. 01 ±2. 22) ng/ml, (44. 80 ±3. 72) mg/L in group C, they were significantly lower than those in group A [(23.23 ±0.51) mmol/L, (302.00 ±5.15) μmol/L, (83.23 ±0.51) ng/ml, (85.60± 6. 32 ) mg/L, P 〈 0. 05 J. And group C were significantly lower than B ( P 〈 0. 05 ). Compared with group A, group B and group C showed lessened pathological changes by TEM. Group C was more gently. Con- clusion Penehyclidine hydrochloride can promote the recovery of renal function in shock rats, reduce the renal ultra - structural changes, in order to reduce renal injury by hemorrhagic shock in rats. And treat- ment with 2. 0 mg/kg penehyclidine hydrochloride produces the most significant protective effect.
