The concentration of vitamin R in the blood was studied in five totally gastrectomized pigs followed for 10–18 months, and in four controls followed for 5¼–8 months. The concentration of vitamin B12 in the liver was investigated in three pigs of each group. The content of vitamin B in the blood was of the same magnitude in both groups. Thus, removal of the stomach does not compromise the normal presence of this vitamin in the blood. The B content in the liver was also unaffected by the operation, whereas it was increased after simultaneous administration of vitamin B.
对5只全胃切除的猪进行了10 - 18个月的跟踪研究，测定其血液中维生素R的浓度，并对4只对照猪进行了5¼ - 8个月的跟踪研究。对每组中的3头猪的肝脏中维生素B12的浓度进行了研究。两组血液中维生素B的含量处于相同水平。因此，切除胃不会影响这种维生素在血液中的正常存在。肝脏中的B含量也不受手术影响，而在同时给予维生素B后会增加。
