A modified method of Jerne's assay was used to determine haemolytic plaque-forming cells (PFC) in mouse spleen. By means of this method we measured the dynamic changes of the immune status in tumor-bearing mice. The tumors used were solid Sarcoma 180 maintained in Tian-jin albino mice, four ascitic tumors including Sarcoma 180 maintained in Tian-jin albino and 615 strain mice, and Hepatoma and Ehrlich carcinoma maintained in C57BL mice. The results. showed that spleen PFC decreased as the tumors...

A modified method of Jerne's assay was used to determine haemolytic plaque-forming cells (PFC) in mouse spleen. By means of this method we measured the dynamic changes of the immune status in tumor-bearing mice. The tumors used were solid Sarcoma 180 maintained in Tian-jin albino mice, four ascitic tumors including Sarcoma 180 maintained in Tian-jin albino and 615 strain mice, and Hepatoma and Ehrlich carcinoma maintained in C57BL mice. The results. showed that spleen PFC decreased as the tumors progressed, and was hardly detected when the tumors were far advanced. The tumor-bearing mice commonly had striking splenomegaly with. decrease in number of small lymphocytes and. increase of 'immature' plasma cells, which might explain the poor immune responses of tumor-bearing mice.

本文应用改良的Jerne氏方法测定小鼠脾脏溶血空斑形成细胞。用此方法测定一株实体瘤(在津白小鼠上移植之肉瘤180)和四株腹水瘤(津白小鼠上移植之肉瘤180,615小鼠上移植之肉瘤180,以及C57BL小鼠上移植之肝癌和艾氏癌)带瘤动物免疫状态的动态变化。结果表明,随着肿瘤进行性生长,小鼠脾脏溶血空斑形成细胞逐渐减少,到晚期几乎不能测得。带瘤小鼠的脾脏普遍增大,病理组织学观察提示带瘤小鼠溶血空斑反应之低下与其脾脏的病理学改变相关。

In a preliminary communication we reported that either the Chinese compound Prescription Yu Ping Phong Sang (a prescription used to replenish vital energy and to strengthen superficial resistance ) or its main component Astragalusexerted a bidirectional effect on PFC.In this work our effort was directed to further exploration Of the effective component of this famous prescription. It was found(1) Among the three Chinese traditional drugs of this compound prescription only Astragalus showed a definite reproducible bidirectional effect on PFC. When Ledebouriellae was administered alone or together with Atra-ctyloidis Macrocephalae only unidirectional inhibition could foe observed; (2) WhenAstragalus was extracted by water and then precipited by ethanol, the effective component seemed to be present in the supernatant, i. e. in the alcohol soluble portion. In addition some experiments have been done which give further evidences that the bidirectional effect of Astragalus is neither a false phenomenon due to "randomization" nor a false phenomenon due to a delay or a speedup of the immune reaction, but a real characteristic action of this Chinese traditional drug.

本文报道玉屏风散中不同组分的作用,重复了我们过去观察到的黄芪对PFC的双向调节作用,又进一步观察到方中佐药——单味防风或防风和白术二味则只有抑制PFC的作用;而黄芪的免疫双调作用不是由于“机遇”,也不是推迟或提前机体免疫反应造成的假象;黄芪水提醇沉上清液——“北芪”具有与黄芪类似的效应,应是黄芪起双调作用的一个重要有效部分。

Neurotropin (NSP) is an extract isolated from the skin of rabbits inoculated with vaccinia virus. The purpose of the present study is to examine the possible action of NSP on the number and function of immunocompetent cells in mice. The experiments showed that NSP had no effect on the numbers of both T and B lymphocytes of normal immunized mouse spleen. And the degree of PFC reaction and titre of specific antibody showed no significant differences when compared the NSP treated group with those of control....

Neurotropin (NSP) is an extract isolated from the skin of rabbits inoculated with vaccinia virus. The purpose of the present study is to examine the possible action of NSP on the number and function of immunocompetent cells in mice. The experiments showed that NSP had no effect on the numbers of both T and B lymphocytes of normal immunized mouse spleen. And the degree of PFC reaction and titre of specific antibody showed no significant differences when compared the NSP treated group with those of control. However, NSP exhibited promotive effect on specific antigen-binding cells in early stage of immune responses. It was also noted that the capacity of human T lymphocytes to form rosettes in vitro was restored markedly by NSP. These results suggest that NSP possesses certain immunostimulating activity, particularly on the specific antigen-binding cells and human T lymphocytes.

本文报道从接种牛痘苗的家兔皮肤组织中提取一种有效成份——向神经素,在体内对免疫小鼠的 ARFC有明显的增高作用,在体外可使胰酶处理的人T淋巴细胞恢复E花环形成的能力,但对正常免疫小鼠脾脏中 T和 B淋巴细胞的分布和 PFC反应以及特异性抗体的产生无明显作用,初步认为向神经素具有一定的免疫增强性能。
