营养措施与抗菌素对急性辐射损伤的疗效

NUTRITION AND ANTIBIOTICS TREATMENT FOR ACUTE RADIATION DAMAGE

成年狗8只,分为治疗组与对照组(每组4只),实验前20天内摄取普通饲料,两组均全身一次照射4.65Gy。照射后对照组不给任何治疗,治疗组给予高热量与高蛋白饲料并在食欲不振时强饲。后者在恢复期有半数狗血清中非蛋白氮高于正常,而且常有腹泻症状,这是否由于高蛋白饲料与强饲所致,尚未探明,但营养措施与抗菌素对急性辐射损伤的疗效是明显的,如动物体重易于维持,贫血与白细胞减少较轻而且恢复较早。另外在30天内治疗组与对照组中各有一只狗死亡,但治疗组死亡狗的活存日数较对照组长。

Eight adult dogs distributed equally into control and therapy groups were fed on stock diet for 20 days and then irradiated whole-bodily with 60Co 4.65 Gy. After irradiation the control group was not given any therapeutic measure but fed on the diet as usual, while the therapy group was given with a larger amount of vitamins and high-caloric and high-protein diet, and sometimes force feeding was taken if the latter showed sign of anorexia. Whether higher values of nonprotein nitrogen in serum of two dogs in restored period and diarrhea happened in the therapy group were attribute to The treatments such as high-protein diet and force feeding were still unknown, the curing effects of nutrition and antibiotics were distinct as shown in that the body weight was easily maintained, and that the anemia and leucopenia wereless severe and recovered early. Moreover, within 30 days both the ther apy andcontrol groups one dog died respectively but survival time of the former was longer than the latter.
