该研究旨在探讨白术多糖对LPS处理后雏鹅脾脏抗氧化能力和细胞凋亡的影响.试验选用80只1日龄马岗鹅,随机分为四组,并在日粮中添加400 mg/kg白术多糖,在第24、26和28日龄腹腔注射2 mg/kg LPS,每次注射结束1h后采集脾脏,观察脾脏组织病理变化,RT-PCR检测脾脏抗氧化酶(CAT、GSH-Px、SOD)、凋亡因子(Apaf-1、Caspase3、Caspase9和Fas)和抗凋亡因子(BCL2)的mRNA表达量.结果显示,白术多糖能显著保护雏鹅脾脏免受LPS导致的组织损伤,具有较好的抗氧化及缓解脾脏细胞凋亡作用.白术多糖能够使LPS处理雏鹅脾脏的抗氧化能力恢复.白术多糖对SOD的影响作用有一定的滞后性.在LPS处理1、2、3次后,均观察到白术多糖使脾脏的抗凋亡能力均显著上升,且在第3次后抗凋亡效果最为明显.
Investigate the effects of polysaccharides of Atractylodes macrocephala(PAMK)on the antioxidant capacity and apoptosis of gosling spleen after different times of LPS treatment.Eighty 1-day-old Magang geese were randomly divided into four groups,and the diet was supplemented with PAMK.2 mg/kg LPS was injected intraperitoneally on the 24th,26th and 28th day of age and spleen was collected 1 hour after the injection.The pathological changes of spleen tissue were observed.The mRNA expressions of spleen antioxidant enzymes(CAT,GSH-Px,SOD),apoptotic factors(Apaf-1,Caspase3,caspase9 and FAS)and anti-apoptotic factor BCL2 were detected by RT-PCR.PAMK can significantly protect the spleen of goslings from the tissue damage caused by LPS,and has a good anti-oxidation and alleviating the apoptosis of spleen cells effect.Among them,PAMK can restore antioxidant capacity of spleen treated by LPS,while PAMK has a certain lag effect on SOD.In addition,PAMK significantly increased the anti-apoptotic ability of spleen after LPS treatment 1,2 and 3 times,and the anti-apoptotic effect was most obvious after LPS treatment 3 times.
