RIST index after a 24 h-fast, followed by a RIST after co-administration of i.p.v. GSH-E 1 mmol kg⁻¹ and i.v. (n=5) or i.p.v. (n=5) SIN-1 10 mg kg⁻¹. I.v. SIN-1 after i.p.v. GSH-E did not change insulin sensitivity while i.p.v. SIN-1 after i.p.v. GSH-E significantly increased insulin sensitivity. Values are means±s.e.m. ^***P<0.001.
