【摘要】:目的探討建立一種新型大鼠單純胰腺創(chuàng)傷模型,并基于損傷面積評(píng)估其傷情變化。方法將大鼠隨機(jī)分為2組,采用自主研發(fā)多功能撞擊儀的3 cm~2(3 cm~2致傷面積組)和6 cm~2(6 cm~2致傷面積組)撞擊頭,分別擠壓各組處于開腹?fàn)顟B(tài)的胰腺,使之在400 k Pa的壓強(qiáng)下形成不同面積的損傷,并設(shè)置對(duì)照組;建模24 h后觀察各組大鼠存活率、一般情況、大體病理和組織病理學(xué)改變,并檢測(cè)血鉀、血鈣的濃度和血清、腹水中淀粉酶及脂肪酶的活性。結(jié)果與對(duì)照組比較,3 cm~2和6 cm~2致傷面積組均能形成明顯的損傷(P0.05),其中,與3 cm~2致傷面積組比較,6 cm~2致傷面積組損傷更顯著(P0.05)。與3 cm~2致傷面積組相比,6 cm~2致傷面積組大鼠存活率、血鉀及血鈣水平更低(P均0.05),一般情況更差,損傷性病理改變的范圍及程度更大,血清淀粉酶、脂肪酶更高(P均0.05)。結(jié)論成功建立了一種基于損傷面積控制的大鼠胰腺創(chuàng)傷模型。該模型簡(jiǎn)單、有效、可控性及可重復(fù)性好,適合用于傷情演化機(jī)制和創(chuàng)傷施救等方面的研究。
[Abstract]:Objective to establish a new simple pancreatic trauma model in rats and to evaluate the injury status based on the injury area.Methods the rats were randomly divided into two groups. The rats were randomly divided into two groups. The rats were randomly divided into two groups. The rats were randomly divided into two groups: the 3 cm~2(3 cm~2 injury area group (3 cm~2(3 cm~2 group) and the 6 cm~2(6 cm~2 injury area group (6 cm~2(6 cm~2 group).After 24 hours of modeling, the survival rate, general condition, gross pathological and histopathological changes of rats were observed, and the concentrations of blood potassium, serum calcium and serum were measured.Activities of amylase and lipase in ascites.Results compared with the control group, the injury area of 3 cm~2 and 6 cm~2 could form significant injury P0.05A, among which, compared with the 3 cm~2 group, the injury of 6 cm~2 group was more significant than that of the 6 cm~2 group.Compared with 3 cm~2 injury area group, the survival rate, blood potassium and blood calcium levels of rats in the 6 cm~2 injury area group were lower (P < 0.05), the general condition was worse, the range and extent of pathological changes were larger, the serum amylase and lipase levels were higher than those in the control group (P < 0.05).Conclusion A rat pancreatic trauma model based on area control was successfully established.The model is simple, effective, controllable and reproducible. It is suitable for the study of injury evolution mechanism and wound rescue.
