Effects of EGb761 on sociability (a) and social memory (b). a During sociability testing, the times spent in the compartment containing C1 was more than C0. In addition, db/db^−/− control mice spent significantly longer pursuing C1 than the other five groups, and the difference compared with WT control was significant (*, P < 0.05, F = 3.013). A: C1 = stranger 1, C0 = empty cage. b During the social memory testing, compared with three WT groups, the mice in dbdb^−/− control and dbdb^−/− 50 mg groups spent more time pursuing C1, and there were also a downward trend of db/db^−/− 50 mg and db/db^−/− 100 mg groups (P = 0.1814, F = 1.606). B: C1 = stranger 1, C2 = stranger 2. n = 8 for WT control, WT 50 mg, WT 100 mg, db/db^−/− control, and db/db^−/− 100 mg; n = 6 for db/db^−/− 50 mg
