FIG. 3.

A: The Mn²⁺-enhanced pancreatic R1 reflected the changes seen in pancreatic insulin content, with pancreatic R1 remaining constant in Tg⁻ mice (white bars) and declining progressively in Tg⁺ mice (*P < 0.01 vs. same-day Tg⁺, #P < 0.05 vs. all other Tg⁺, &P < 0.05 vs. day 7 Tg⁺) after cyclophosphamide injection. White bars, Tg⁻ mice; black bars, Tg⁺ mice. B: Mn²⁺-enhanced pancreatic R1 correlated well with total pancreatic insulin, with R² = 0.76. White squares, Tg⁻ mice; black diamonds, Tg⁺ mice.
