摘要:

旨在探明饮水中添加不同剂量硼酸对 45 d非洲雏鸵鸟肺组织形态学的影响。1 d非洲雏鸵鸟 24 羽,随机分为 6 组,分别在饮水中添加 0(A 组,对照组)、40(B 组)、80(C 组)、160(D 组)、320(E 组)、640 mg•L-1(F 组)剂量的硼酸。饲喂至45 d 取肺组织进行石蜡包埋,切片,通过 HE 染色,MASSON 染色和TUNEL 技术进行分析。与对照组相比,HE 染色观察发现,添加40和80 mg•L-1硼酸剂量组,肺组织结构清晰,发育良好,无明显病变,而从160 mg•L-1剂量开始,肺组织形态结构出现病变,异嗜性粒细胞增多,炎症反应加重,细胞间质增厚;MASSON 染色观察发现,320和640 mg•L-1 剂量组肺组织胶原纤维沉淀明显增加;运用 IPP 软件对 TUNEL试验结果进行统计显示,添加硼酸剂量 40 mg•L-1 时可减少雏鸵鸟肺组织细胞凋亡,剂量高于320 mg•L-1 时增加肺组织细胞凋亡。综合上述结果,在饮水中添加硼酸,40 mg•L-1 时可减少雏鸵鸟肺组织细胞凋亡,剂量高于160 mg•L-1 时能促进肺组织中发生炎症反应,剂量高于 320 mg•L-1 时能增加肺组织细胞凋亡和诱导肺纤维化。

Abstract:

The aim of the present study was to detect the effects of boric acid on the morphology of African ostrich chick lung.Twenty-four healthy ostrich chicks were randomly divided into 6 groups:Group A(control group),B,C,D,E,F,and supplemented with boric acid at the concentration of 0,40,80,160,320,and 640 mg•L-1,respectively.The morphology changes of lung were observed by using light microscope and the HE staining technology,the collagen fiber changes were detected by MASSON staining,and TUNEL methods were used to label the apoptosis cells in ostrich lung.The results were as followings,compared with the control group,when the boric acid dose less than 80 mg•L-1(group A,B,C),the lung structure was well developed,cell morphology was intact,nucleus was stained darkly and the lung organizational structure was clearly,especially at 80 mg•L-1.Adversely,when boric acid doses higher than 160 mg•L-1(group D,E,F),the high dose boric acid damaged the lung tissue structure,heterophilic granulocytes were increased,the interstitial was thickening with HE staining,especially at 640 mg•L-1.MASSON staining showed that compared with the control group,collagen deposition was increased in high dose boric acid group(more then 320 mg•L-1 boric acid).Compared with control group,the IOD of apoptosis cells was significantly decreased in the 40 mg•L-1 boric acid group,whereas,the IOD of apoptosis cells was significantly evaluated in the 320 and 640 mg•L-1 boric acid groups.Add 40 mg•L-1 boric acid can inhibit apoptosis in lung,more than 160 mg•L-1 boric acid can promote inflammation,more than 320 mg•L-1 boric acid can increase apoptosis and cause pulmonary fibrosis.
