Effects of Tualang honey and E2 on anxiety-like behaviour. (a) Mean rearing number was significantly increased in stressed OVX rats treated with either E2 or Tualang honey compared with untreated stressed OVX. (b) Mean freezing time (s) was significantly decreased in stressed OVX rats treated with either E2 or Tualang honey compared with untreated stressed OVX. (c) Mean grooming time (s) was significantly decreased in stressed OVX rats treated with either E2 or Tualang honey compared with untreated stressed OVX. (d) Mean duration of crossing line (s) was significantly increased in stressed OVX rats treated with either E2 or Tualang honey compared with untreated stressed OVX. (e) Mean number of boli rearing number was significantly decreased in stressed OVX rats treated with either E2 or Tualang honey compared with untreated stressed OVX. (f) Mean number of face washing was not significantly different between the experimental groups. The data are shown as means ± S.E.M. *P < 0.05 **P < 0.001 denote significantly different values from stressed OVX group. ^#P < 0.05 ^##P < 0.001 denote significantly different values from nonstressed sham-operated control group.
