| 中文摘要: |
| 目的：对肝硬化门静脉高压症大鼠行脾切除手术，观察术后大鼠免疫系统功能的变化情况，探讨脾切除术对免疫系统的影
响，为临床治疗提供理论基础。方法：选取SD大鼠45 只建立PHT模型，随机分为PHT 组、脾全切组及部分脾切除组，每组各15
只。另选取10 只健康大鼠为对照组。分别对四组大鼠行不同的脾切除方案，术后检测四组大鼠的血常规、免疫球蛋白含量、T 淋巴
细胞亚群的变化及组织病理学染色结果等，分析各指标的意义。结果：四组大鼠血常规检测结果显示，PHT 组大鼠WBC高于对照
组，PHTTS 组高于PHT 组，PHTSS 组高于PHTTS 组，差异显著且具有统计学意义(P<0.05)。四组大鼠血浆中IgG 含量差异显著
(P<0.05)；IgA、IgM 含量无显著性差异(P>0.05)。四组大鼠CD4+、CD8+含量差异显著(P<0.05)；CD29+含量无显著性差异
(P>0.05)。结论：脾脏直接参于细胞介导免疫调节，脾切除可降低门脉压力，消除脾亢，有利于肝硬化门脉高压症的缓解。 |

| Objective:To discuss the effects and significance of splenectomy on the immunity of rats with portal hypertension so
as to make a reference for the clinical surgery.Methods:Forty-five SD rats were selected to make the PHT model and randomly divided
into the three groups which referred to the PHT group, the PHTTS group that taking the total splenectomy surgery and the PHTSS group
that undergoing the partial splenectomy surgery. Another fifteen healthy rats were chosen as the control group. Then the detection of the
blood, the immunity, the T lymphocyte subsets and the pathological changes of the rats were observed and analyzed.Results:There was
statistically significant difference of blood routine of rats between the four groups (P<0.05); There was statistically significant difference
of IgG in the plasma of rats between the four groups (P<0.05); There was no statistically significant difference about the IgA and IgM
(P>0.05); There were statistically significant differences of CD4+ and CD8+ of rats between the four groups (P<0.05); There was no
statistically significant difference about CD29+ of rats between the four groups (P>0.05).Conclusion:It is indicated that the splenectomy
could reduce the portal pressure, eliminate the port and relieve the cirrhotic portal hypertension. |
