本研究之目的在觀察B A L B /c處鼠口腔結膜接受放射線照射後之病理變化,並分析維生聚丙(抗壞血酸﹒ a s c o r b i c ac泊, AA)改變這些病理變化之程度, 以進一步了解在活體情況下﹒AA 與放射線黏膜炎( ra d i at i o n m ucos itis)之閱(系。綜合各組健息之病理變化可知, 接受單次照射850 cGy (2000 cGy/10 Fr/2 wks)至105日cGy (3000 cGy/ 15 Fr/3 wks)之處鼠﹒ 口腔切片內出現輕微多形核細胞(po lymorphonuclearcells , PMN )浸潤。上皮部份脫落及上皮下水泡形成在1250 cGy (4000 cGy/20 Frl4 wks)照射量時形成。而胞核內空泡及嚴重血管周圍及肌細胞間充血在照射量達到1 5 7 9 cGy (切∞ cG Y/2 5Fr / 5 wks)開始出現。至於更嚴重的上皮全部脫落則是在照射量達到1772 cGy (6∞ o cGy/3日Fr/6 wks)開始出現。所有這些放射線照射引起的病理變化程度如果在照射前加入AA後都會明顯,成輕0 *研究結果亦顯示: AA 對路鼠口腔黏膜及其下層肌肉結締組織能減少幅射照射產生之發炎效應,其劑量調登因子(d o se modif ication factor, DMF)值鈍固自1.28 至卜的。
The histological effects of radiations on mouse oral mucosa and its modific ati on by ascorbic acid were studied. At a single dose range between 850 cGy (equival ent to 2000 cGy/ l0 Fr/ 2 wks) and 1050 cGy (equivalent to 3000 cGy/1 5 Fr/3 wks), the pathological change in oral mucosa of the BALB/c mice showed mild degr ee infiltrati on of polymorphonuclea r cells (PMN). Partial epidermal drop and subepidermal blist ers formati on were noted at 1250 cGy (4000 cGy/ 20 Fr/4 wks). Nuclear vacuolization, severe perivascular and intermuscle cell congestion were noted after exposure to a dose of 1579 cGy (5000. cGy/ 25 Fr/ 5 wks) irr adiati on. Fur therm ore, complete drop of the keratin layer was noted after 1772 cGy (6000 cGy/ 30 Fr/6 wks). All these hist ological effects were ameliorated when ascorbic acid was added before irradiat ion. It also showed that AA reduced the severity of radiation inflammati on in the oral mucosa, submucosa l muscle and connective tissues of mice, and the modifica tion facto r of ran ge from 1.28 to 1.66.
