Figure 1From: Long-term follow-up of nephrotoxicity in rats administered both melamine and cyanuric acidMicroscopic appearance of kidney sections according to age in Group M + C Crystal distributions are observed using polarized light optical microphotography (a-c), and scarring was noted with HE staining (d-f) of the paraffin-embedded axial sections in Group-M + C at day 28 in rats aged: 6 weeks (a, d), 10 weeks (b, e), and 26 weeks (c, f) (×20). Arrowheads indicate crystals, and arrows indicate scarring. Inset in (d) reveals the kidney scarring (×190).Back to article page
