It has been shown in several experiments that the heat-labile, growth-promoting factor "V" found in the blood of animals does not diminish or disappear when the animals are kept on vitamine B-free diet. The titer of the "V" substance present in the blood of normal animals is undiminished in animals showing severe signs of polyneuritis even to the time of their death. The antipolyneuritic factor of vegetable food, designated as vitamine B, is found to be considerably more heat-stable than is the "V" substance concerned in promoting the growth of Pfeiffer's bacillus.
已在几项实验中表明,动物血液中发现的不耐热、促进生长的因子“V”,在动物接受无维生素 B 饮食时不会减少或消失。即使在出现严重多发性神经炎症状的动物死亡时,正常动物血液中存在的“V”物质的效价也没有降低。植物食物中的抗神经炎因子,被指定为维生素 B,被发现比促进 Pfeiffer 杆菌生长的“V”物质更耐热。
