【摘要】:目的考察山茶油對無水乙醇和消炎痛致小鼠胃潰瘍的防治作用,以及對血清超氧化物歧化酶(SOD)活性和一氧化氮(NO)、丙二醛(DMA)含量的影響。方法采用無水乙醇和消炎痛方法建立兩種小鼠胃潰瘍模型,每種動物模型采用50只雄性ICR小鼠,隨機(jī)分為模型組、雷尼替丁組(30 mg/kg)和山茶油低、中、高劑量組(1 mL/kg、2 mL/kg和3 mL/kg),每組10只動物。用山茶油預(yù)防性處理5 d后分別采用無水乙醇灌胃和皮下注射消炎痛的方法建立小鼠胃潰瘍模型。計算各組小鼠的胃潰瘍指數(shù),并測量血清NO、DMA的含量和SOD活性。結(jié)果與模型組相比,山茶油預(yù)防處理可以劑量依賴性地降低由無水乙醇和消炎痛所致胃潰瘍的胃潰瘍指數(shù)。山茶油在2 mL/kg和3 mL/kg的劑量下可以使乙醇致胃潰瘍小鼠的胃潰瘍指數(shù)從(29.3±17.0)分別降低至(14.0±19.4)和(8.3±12.8),抑制率分別達(dá)到52.22%和71.67%,差異有統(tǒng)計學(xué)意義(P0.05);同時3 mL/kg的山茶油可以顯著降低由消炎痛導(dǎo)致的胃潰瘍小鼠的胃潰瘍指數(shù)[從(27.2±10.1)降低至(13.1±4.3)],抑制率為51.84%,差異有統(tǒng)計學(xué)意義(P0.05);血清MDA、NO和SOD測定結(jié)果顯示,山茶油中、高劑量處理與模型對照組相比可以顯著降低無水乙醇導(dǎo)致的胃潰瘍小鼠的血清MDA含量,并提高NO含量和SOD的活性,差異均有統(tǒng)計學(xué)意義(P0.05)。結(jié)論山茶油對由無水乙醇和消炎痛導(dǎo)致的胃潰瘍均具有明顯的保護(hù)作用,其防治功效可能與提高血清中SOD活性、升高血清NO含量并降低MDA水平有關(guān)。

Methods Two kinds of gastric ulcer mice models were established by ethanol and indomethacintreatment. In each kind of animal models, fifty male ICR mice were randomly divided into model group, ranitidine group(30 mg/kg), and low-, medium- and high-dose camellia oil (1 mL/kg, 2 mL/kg, and 3 mL/kg) groups, with 10 animals ineach group. Animals were preventively treated for 5 days, then given ethanol (p.o) or indomethacin (i.m.) to establish gas-tric ulcer models. The gastric ulcer index of each group was calculated, and the serum levels of NO, MDA, and SOD weremeasured by specific kits. Results Compared with the model group, preventive treatment with camellia oil dose-depend-ently reduced the ethanol- and indomethacin-induced gastric ulcer. Camellia oil at 2 mL/kg and 3 mL/kg reduced the gas-tric ulcer index in ethanol-induced mice from (29.3±17.0) to (14.0±19.4) and (8.3±12.8), with an inhibition rate of 52.22%and 71.67%, respectively, and the difference was statistically significant (P<0.05). At the same time, 3 mL/kg of camelliaoil also significantly reduced the gastric ulcer index in indomethacin-induced mice from (27.2±10.1) to (13.1±4.3), withan inhibition rate of 51.84%, and the difference was statistically significant (P<0.05). Serum MDA, NO and SOD quanti-fication showed that camellia oil at the doses of 2 mL/kg and 3 mL/kg significantly reduced the serum level of MDA,and increased the content of NO and the activity of SOD, as compared with the model group (P<0.05). Conclusion Ca-mellia oil is adequate to prevent alcohol- and indometacin-induced gastric ulcer, and its therapeutic effect may be relatedto the improvement of oxidative stress (increase of NO level and SOD activity, decrease of MDA level) in animals.【Key words】 Camellia oil; Gastric ulcer; Superoxide dismutase (SOD); Nitric oxide (NO); Malondialdehyde (MDA)doi:10.3969/j.issn.1003-6350.2018.07.003
