[Changes in the content of the thiol form of the acetylation coenzyme in the liver during administration of vitamin B3-active compounds to intact and locally irradiated animals].

A local exposure of mouse head to gamma-rays caused phase changes in CoASH content of the liver. The administration of D-pantothenate-Ca and D-pantethine increased the level of CoASH in the liver of exposed animals; calcium D-homopantothenate did not influence the co-enzyme content. It is suggested that pantothenate and pantethine act like vitamins while the influence of homopantothenate is associated with the effects of calcium ions.
