Values are expressed as mean ± SEM of 6 rats/group. NC: normal control; FC: fasting control; FG: fasting with glucose (2 gm/kg b.w.); FGF: fasting with glucose (2 gm/kg b.w.) and WSF of A. esculentus (2 gm/kg b.w.); and FGC: fasting with glucose and CMC. a 𝑃 < 0 . 0 5 compared to FG; b 𝑃 < 0 . 0 5 compared to FGC (ANOVA followed by Dunnett's test).
