Abstract:
Objective To monitor the association between the expression of ve-cadherin and mesentery microcirculation blood flow of sepsis CASP rats,Analysis the relationship of each other.Methods Based on the standard criteria,we established sepsis CASP rats,and the rats were divided into several groups according to the gauge of the vein detained needle in the ascending colon,every group has six rats.The groups consisted of Sepsis A group 22 G(0.9 mm× 25 mm,33 ml/min),sepis B group 20 G(1.1 mm ×32 mm,54 ml/min),sepsis C group 18 G(1.3 mm ×32 mm,80 ml/min),sepsis D group 14 G(2.0 mm ×45 mm,270 ml/min),in addition we established the control group.Real-time observation was performed by microscope on the 6 h's blood velcocity of each sepsis CASP rats group.Then we applied the immunohistochemistry to quantitatively analyze the expression of ve-cadherin of each group.Results The blood velcocity of the mesentery microcirculation in control group was (583.21 ±52.39) μm/s,it was higher compared with the sepsis D group(213.30 ±52.39) μm/s (P ＜0.05),the blood velocity in sepsis A group was (482.71 ± 58.62) μm/s,higher compared with the sepsis D group(P ＜ 0.05).The score of the immunohistochemistry quantitative analysis of mesentery ve-cadherin in control group was 11.17 ±0.34,higher compared with the sepsis D group(5.43 ±0.43)(P ＜0.01).The score of sepsis A group was 10.07 ±0.30,higher compared with the sepsis D group(P＜0.05).Conclusions The expression of ve-cadherin of sepsis CASP rats had positive correlation with the blood velocity of the mesentery microcirculation of sepsis CASP rats,and it can indirectly reflect the degree of the sepsis.
