Fig 1. Chronic exposure of mouse primary PAC to nicotine decreases the carrier-mediated [³H]thiamin uptake.

Primary PAC were isolated from mice exposed to nicotine and their controls. Carrier -mediated [³H] thiamin uptake was determined as described in “Materials and Methods”. Data are means ± SE of at least three separate uptake determinations from multiple sets of mice. *P < 0.01.
