Effect of interleukin - 15 on microbicidal activity of human peripheral blood polymorphonuclear cells against candida albicans 白介素15對人外周血嗜中性粒細胞抗白念珠菌活性的影響
Previous investments have shown that chitin , chitosan or their oligosaccharides were able to stimulate immune system . either intravenously or intraperitoneal administered to mouse , these polysacca - rides or oligosaccharides were able to increase polymorphonuclear cells in blood or peritoneal exudate , and activated macrophages , t lymphocytes and nk cells of mouse 將這些多糖、寡糖經腹腔或靜脈給予小鼠,可以使其腹腔滲出液及外周血中多型核白細胞增多,巨噬細胞、脾臟t淋巴細胞、 nk細胞等活性增強。
P - selectin was negative both in the normal skin and in the postmortem damage group . in the wound specimens aged 1h , we detected expression of icam - 1 in the epidermis , a strong positive staining was observed in 3 hours after wound , and continued to 1 days from the skin was injured after incised , weak staining were showed on epiderm of the injury margin after 3 days incised , and disappeared in 5 days . expression of icam - 1 was also detectable in polymorphonuclear cells ( pmns ) in the wound specim - ents aged 3h 本實驗研究證明,皮膚損傷后表皮層icam1表達增高,其表達呈現一定時間規(guī)律性,在損傷后lh ,損傷邊緣表皮細胞即呈黃褐色染色,傷后3h組, icam一二在表皮層中呈深黃褐色,并一直持續(xù)至傷后id ,傷后3d組icam 1染色轉淡,呈黃褐色染色,在傷后sd及7d組, 1 m一二表達基本恢復至正常狀態(tài)。
