We examined the protective effect of L-citrulline on ethanol-induced gastric ulcer in rats.The gastric lesions were significantly attenuated by all doses of L-citrulline as compared to the ethanol (0.8ml/kg body weight) treatment group.Pretreatment with L-citrulline prevented the oxidative damage as well as the increase of the myeloperoxidase (MPO) activity.The gastric mucosal constitutive NO synthase (cNOS) and inducible NO synthase (iNOS) activities were also investigated in tissues of all groups.The administration of L-citrulline increased the eNOS activity and decreased the iNOS activity as compared to ethanol-treated group.Analysis of serum cytokines of ethanol-induced rats showed a moderate decrease in interleukin-10 (IL-10) with considerable increase of interleukin-6 (IL-6) while L-citrulline inhibited the acute alteration of cytokines.These results suggest the gastroprotective effect of L-citrulline.

PTEN是具有磷酸脂酶活性的抑癌基因,是双特异蛋白磷酸酶家族(DSPs)的成员,同时具有脂质磷酸酶和蛋白酪氨酸磷酸酶活性。而在肿瘤增殖,侵袭,迁移的过程中,肿瘤血管生成作为肿瘤发生发展中一个关键因素已越来越受到人们的关注。抑癌基因PTEN可以参与PI3K/Akt信号通路,调控缺氧诱导因子1,基质金属蛋白酶,血管内皮生长因子,钠氢交换调控因子1,酪氨酸激酶受体等血管生成相关信号以及一些机体氧化产物来
免疫系统在肝纤维化的发展过程中起到重要的作用,近年来的研究发现,NK细胞及其受体积极参与了抑制肝纤维化的过程,NK细胞对活化型肝星状细胞具有靶向性杀伤作用。本文综述NK细胞及其受体在肝纤维化中的作用,期望NK细胞能成为今后治疗肝纤维化研究中的一个新的药物干预靶标。
