Objective To investigate the effect of Propranolol and Phentolamine on neurogenic pulmonary ede-ma(NPE)in rats. Methods One hundred and twenty male Wistar rats were randomly divided into 4 groups:the con-trol group(group A),the NPE group(group B),the Propranolol treatment group(group C)and the Phentolamine treatment group(group D),30 cases in each group. Diffuse brain injury was induced in the latter 3 groups. The lung wet/ dry ratio was calculated. HE staining was used to measure the histological changes in the lung tissues. The levels of neuropeptide Y(NPY)and substance P(SP)in the serum and the bronchoalveolar lavage fluid(BALF)were detected by enzyme - linked immunosorbent assay(ELISA). The expressions of NPY and SP in the lung tissues were demonstra-ted by immunohistochemical staining,and immunohistochemical scores(IHS)were measured after scarifying the ani-mals at different time points(0. 5,6. 0 and 24. 0 h after injury). Results Compared with group A,water volume in the lungs in group B increased at 24. 0 h(P ﹤ 0. 05);NPY content in the serum was elevated at 6. 0 h,while that in BALF was elevated at 6. 0 h and 24. 0 h(all P ﹤ 0. 05);SP content in the serum was elevated at 0. 5 h and 6. 0 h(all P ﹤0. 05),while that in BALF was elevated at 0. 5 h(P ﹤ 0. 05);The expression of NPY protein in the lung tissue in-creased at 0. 5 h,6. 0 h and 24. 0 h(all P ﹤ 0. 05),while the level of SP protein increased at 0. 5 h(P ﹤ 0. 05). Com-pared with group B,water volume in the lungs in group C was higher at 6. 0 h and 24. 0 h(all P ﹤ 0. 05);NPY concen-trations in the serum were higher at 6. 0 h and 24. 0 h(all P ﹤ 0. 05),while those in BALF were higher at 0. 5 h, 6. 0 h,and 24. 0 h(all P ﹤ 0. 05);SP concentrations in serum and BALF were higher at 0. 5 h(all P ﹤ 0. 05). The ex-pression of NPY protein increased at 6. 0 h(P ﹤ 0. 05),while the levels of SP protein increased at 0. 5 h,6. 0 h and 24. 0 h(all P ﹤ 0. 05). Compared with group B,the level of NPY in serum in group D was lower at 6. 0 h,and that in BALF was lower at 6. 0 h and 24. 0 h(all P ﹤ 0. 05). The level of SP in serum was lower at 0. 5 h(P ﹤ 0. 05). The ex-pression of NPY protein decreased at 6. 0 h and 24. 0 h(all P ﹤ 0. 05),while the levels of SP protein decreased at 0. 5 h(P ﹤ 0. 05). Conclusions Phentolamine is effective in reducing NPE through reduction of NPY and SP,while propranolol can stimulate the release of NPY and SP to aggravate NPE following traumatic brain injury in rats.
