Histograms of the kinetic analysis parameters for spontaneous contractive activity of circular smooth muscles of the caecum (C, control; 30 and 100, term (days) of burdening the rats with the suspension of nanosize titanium dioxide material): (1) frequency of preparation contractions for 10 min; (2) averaged value of the duration of contraction–relaxation cycle (sec); (3) MU index of contractions; and (4) AU index of contractions. *p < 0.05, reliability of changes compared to the control
