本文收集了慢性放射性皮肤损伤63例。讨论了放射性皮肤损伤的病理过程,并且描述了临床特征。除5例手术切合口愈合不良外,其余病例均可见到程度不同的典型慢性放射性皮肤病变。最后叙述了治疗原则和措施,着重介绍了一种新的治疗方法——药物疗法(应用含甲_2巨球蛋白的生物制剂)和手术疗法相结合。在进行追踪观察的46例中,单纯药物治疗32例,有效者24例;结合手术治疗14例,无一例失败。

Three patients of chronic radiation disease having typical clinical symptoms were selected as experimental subjects. They took high-protein diet containing 1586-1669 kcal, 75.4-77.2g protein, 162.4-183.0g carbohydrate and 69.7-69.8g fat. Apparent digestibilities of protein, carbohydrate and fat in the diet were estimated as 85.9-87.3, 98.8-99.3 and 94.7-96.1% respectively. Nitrogen balances of three patients were -0.90, -0.31 and -0.01g per day. During that period, patients' body weight dropped 0.5-1.5kg.Afterward...

Three patients of chronic radiation disease having typical clinical symptoms were selected as experimental subjects. They took high-protein diet containing 1586-1669 kcal, 75.4-77.2g protein, 162.4-183.0g carbohydrate and 69.7-69.8g fat. Apparent digestibilities of protein, carbohydrate and fat in the diet were estimated as 85.9-87.3, 98.8-99.3 and 94.7-96.1% respectively. Nitrogen balances of three patients were -0.90, -0.31 and -0.01g per day. During that period, patients' body weight dropped 0.5-1.5kg.Afterward two patients received the diet therapy of a high-protein high-calorie diet specially prepared and given at six meals instead of four meals per day. The daily intakes of protein, fat, carbohydrate and calories were increased to 97.2g, 94g, 308-312g and 2467-2483 kcal respectively. The digestibility of protein in the therapeutic diet was slightly higher than that in hospital diet, but those of carbohydrate and fat did not change obviously. The nutritional status of two patients became better as shown by that the nitrogen balance turned positive ( + 2.37 and +2.93g per day) and the body weight increased.

选择三例慢性放射病患者进行了两期氮平衡实验,每期三日。第一期:当膳食中蛋白质摄入量为75.4~77.2g,热量为1586~1669kcal时,氮平衡为-0.01~-0.50g,第二期:当膳食中蛋白质和热量分别增加至97.2g和2467~2483kcal时,氮平衡为+2.37~+2.93g。两期的蛋白质、脂肪、糖的表观消化率基本相似,显然第一期出现的负氮平衡与蛋白质和热量摄取量不足有关。文中指出,在治疗慢性放射病患者时,应注意供给高热量和高蛋白质的膳食。

Dogs were continualy exposed to ~(80)Co r-rays at dose rates of 0. 427and 0. 178 rad/day respectively for 3 years. The accumulated doses were 315. 2 radand 131 .4 rad respectively. During the period of radiation and 3 years after, chro-mosome aberrations in peripheral blood lymphocytes haye been observed. The resultsshowed that the chromosome aberrations were mainly one hit-aberration, and the acen-tric fragmentt increased linearly with accumulated dose. According to the results, theacentric fragments can be used as a sensitive index for chronic radiation injury.Following three and six months after exposure the frequencies of acentric fragmentdecreased near to and within the control level respectively.

本研究用0.427rad/d和0.178rad/d两种剂量率~(60)Co-γ线连续照射狗三年,其累积剂量分别为315.2rad和131.4 rad。在照射期间及停照后三年内对实验狗的外周血淋巴细胞染色体畸变进行了观察。结果表明,染色体畸变主要为一次击中畸变,其中无着丝点断片畸变率与累积剂量呈线性相关,在一定剂量范围内,可考虑作为慢性辐射损伤的灵敏指标。停照后三个月时,无着丝点断片畸变率已接近对照组水平。自停照后六个月开始,照射组动物的畸变率都在自发畸变率范围变动。本实验揭示建立低剂量率长期照射的剂量—效应曲线的可能性值得进一步探讨。
