作者曾发现维生素A可提高鼠的免疫能力并增加腹腔内牯连形成.为进一步了解维生素A及其前体β胡萝卜素对腹内脓毒症是否有局部和(或)全身性影响,作者进行了以下实验.方法:取雄鼠50只,随机分为三组.Ⅰ组20只(对照),每公斤饲料含维生素A15,000IU(相当一般饲料中含量的2～3倍)及β胡萝卜素6.5mg.Ⅱ组20只,在每公斤上述饲料内又增添维生素A150mg(提高6倍).Ⅲ组10只,每公斤上述饲料内增添β
The authors have found that vitamin A can increase the mice’s immune ability and increase the formation of intra-abdominal junctions. To further understand whether vitamin A and its precursor β-carotene have local and (or) systemic effects on intra-abdominal sepsis, the authors conducted The following experiments. Methods: 50 male rats were randomly divided into three groups. Group I was 20 (Control), containing 15,000 IU of vitamin A per kilogram of feed (comparable to 2 to 3 times of the general feed) and β-carotene. In the 6.5 mg.II group, 20 were added with 150 mg of vitamin A per kilogram of the above feed (a 6-fold increase). 10 rats in group III were added with β per kilogram of the above feed.
