BACKGROUND
Severe acute pancreatitis (SAP) features fatal pathogenetic conditions and high mortality rate. The study of SAP complicated with multiple organ injuries is of important significance. In this study, we explored the protective effect of baicalin on multiple organs of SAP rats and compared it with that of octreotide through light and electron microscopic observations of the pathological changes.
METHODS
The improved Aho method was used to prepare SAP rat models. These rats were then randomly divided into a sham-operated group (n=45), a model control group (n=45), baicalin-treated group (n=45) and octreotide-treated group (n=45). Based on the difference in time points after operation, these groups were subdivided into 3, 6 and 12 hour subgroups (n=15). At the corresponding time point after operation, the mortality rate of rats was recorded, and then the rats were humanely killed to take samples of multiple organs that were subsequently examined for pathological changes under light and electron microscopy.
RESULTS
At 12 hours after operation, the mortality rate of rats in the baicalin- and octreotide-treated groups was lower than that in the model control group (P<0.05). Compared to the model control group, the pathological changes and pathological scores in the baicalin- and octreotide-treated groups were mitigated and relieved to varying degrees. The pathological changes under electron microscopy were also improved.
CONCLUSIONS
Both baicalin and octreotide show good protective effects on multiple organs of SAP rats. Baicalin as a new drug has good prospects in the treatment of SAP.
背景
重症急性胰腺炎(SAP)具有致命的发病机制和高死亡率。研究SAP并发多器官损伤具有重要意义。在本研究中,我们通过对病理变化的光镜和电镜观察,探讨了黄芩苷对SAP大鼠多器官的保护作用,并与奥曲肽进行比较。
方法
采用改良的Aho法制备SAP大鼠模型。然后将这些大鼠随机分为假手术组(n = 45)、模型对照组(n = 45)、黄芩苷治疗组(n = 45)和奥曲肽治疗组(n = 45)。根据术后时间点的不同,将这些组再细分为3小时、6小时和12小时亚组(n = 15)。在术后相应时间点记录大鼠死亡率,然后人道处死大鼠,取多个器官样本,随后进行光镜和电镜下的病理变化检查。
结果
术后12小时,黄芩苷治疗组和奥曲肽治疗组大鼠的死亡率低于模型对照组(P < 0.05)。与模型对照组相比,黄芩苷治疗组和奥曲肽治疗组的病理变化和病理评分均有不同程度的减轻和缓解。电镜下的病理变化也有所改善。
结论
黄芩苷和奥曲肽对SAP大鼠的多器官均显示出良好的保护作用。黄芩苷作为一种新药,在SAP治疗中具有良好的前景。
