PFI of rats treated with aqueous extracts of H. erinaceus fresh fruiting bodies or mecobalamin returned to pre-surgery values 4–7 days earlier than negative control. Values on day 0 are before surgery. Data are expressed as means ± standard deviation (n = 10 for day 0, 7 and 10 in all groups, day 4 in aqueous extract or mecobalamin group, day 14 in negative control group; n = 2, n = 4 and n = 3 for day 14 in low dose of aqueous extract, high dose of aqueous extract and mecobalamin group, respectively; n = 5 for day 17 in negative control group). Brackets indicate number of rats with PFI which had returned to pre-surgery values. Means with different letters in a same column are significantly different (P < .05, one-way ANOVA).
