The transplantable argyrophilic gastric carcinoids producing histamine found in Praomys (Mastomys) natalensis contained no significant amount of vitamin B12-binding proteins. It was also demonstrated that the concentration of vitamin B12-binding proteins in glandular stomach of mastomys was much lower than those in the same tissues of the rat or mouse.
在南非多乳鼠（原称非洲沼鼠）中发现的可移植的嗜银性胃类癌能产生组胺，但其所含的维生素B12结合蛋白量并不显著。此外还表明，多乳鼠腺胃中维生素B12结合蛋白的浓度远低于大鼠或小鼠相同组织中的浓度。
