Consistent relationship was not found between the serum concentrations of immunoglobulin IgM and IgG and the concentration of blood lymphocytes (Bendixen index) in 289 Holstein-Friesian heifers and cows from a dairy herd in which bovine lymphoma had been identified repeatedly. Serum IgM was present in all cattle, and those cows with highest concentrations of blood lymphocytes generally had higher levels of IgM.
在一个曾多次发现牛淋巴瘤的奶牛场的289头荷斯坦-弗里生小母牛和母牛中，未发现血清免疫球蛋白IgM和IgG浓度与血液淋巴细胞浓度（本迪克森指数）之间存在一致关系。所有牛的血清中均存在IgM，血液淋巴细胞浓度最高的那些母牛的IgM水平通常也较高。
