蚯蚓提取物对小鼠脾脏抗体形成细胞的影响 总被引:10,自引:0,他引:10
作用定量溶血分光光度法(QHS)同时测定正常和荷瘤BALB/c小鼠各40只脾脏抗体形成细胞的变化,观察蚯蚓提取物对B细胞介导的免疫应答的影响。结果表明,蚯蚓提取物连续灌胃7d后,使正常小鼠脾脏抗体形成细胞由1.117±0.035增至1.291±0.103(OD值)(P<0.01);荷瘤小鼠由1.045±0.062增至1.343±0.173(P<0.01).提示蚯蚓提取物能调节B细胞的增殖和分... 相似文献

Earthworm capsule is an extract from earthworm made in our laboratory.From1986 to 1989,486 patients with carcinoma of esophagus or lung were randomly divided into 2groups,one group received radiotherapy alone(control group)and the other radiotherapycombined with earthworm capsules(treatment group).All cases were diagnosedpathologically or cytologically.In a two-month treatment course,earthworm capsuleswere given orally twice a day,2~3 capsules each time,each capsule containing 60 mg ofthe extract.Compared with the control group,the CR(complete remission)rate andCR+PR(partial remission)rate in patients with carcinoma of esophagus treated byradiotherapy in combination with earthworm capsule increased 9.7%(P<0.01) and 9.6%(P<0.05),while in patients with carcinoma of lung,they increased 10.6%(P<0.05)and13.5%(P<0.05),respectively.The earthworm capsule caused irritation in the alimentarytract,the patients displaying slight nausea and vomiting(16.7% in thecombination treatment group and 10.0% in the control group).However,these side ef-fects could be alleviated when capsules were taken after meal or with honey concomitantly.No deleterious effects on the heart,liver,kidney,skin,hematopoietic or nervous systemwere seen. 相似文献

前报已证实小鼠~(60)Co-γ射线照射后小肠中cAMP含量升高和cGMP含量降低,而且cAMP含量升高与DNA合成抑制关系密切。cAMP水平保持稳定是受两种酶控制的:腺苷环化酶(AC)和环核苷酸磷酸二酯酶(PDE)。一般认为电离辐射使敏感组织中的AC活性增高而对PDE活性影响不大。至于AC活性增高的原因文献报导 相似文献
