title: Effect of long-term treatment of two tobacco-specific N-nitrosamines on the vitamin A status of mice.
abstract: The effect of long-term treatment of two important tobacco-specific N-nitrosamines, N'-nitrosonornicotine (NNN) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), on the depot or circulating levels of vitamin A of Swiss and BALB/c male mice was studied. It was observed that treatment of both NNN and NNK in Swiss and BALB/c mice decreased liver vitamin A levels significantly. NNK treatment also caused a decrease in the levels of vitamin A in plasma.
