a Typical distributions of W-LPNs and pW-LPNs in rat jejunum and typical particle absorption in Peyer’s patches after oral gavage. (scale bar = 100 μm). b Quantitative analysis of particles in Peyer’s patch tissue (mean ± SD, n = 3). c S/C-suspension, S/C-LPNs, S/C-W-LPNs, and S/C-pW-LPNs concentration–time curves for SLB (left) and CT (right) in rats following ig administration at 80 mg/kg (mean ± SD, n = 5). ***P < 0.001
