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.
Effects of Polysaccharides of Atractylodes Macrocephala on Antioxidant Capacity and Apoptosis in the Spleen of Goslings Treated with LPS
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.
