Effects of rhubarb and the active ingredients of rhubarb on the cytoplasmic free calcium in INT-MNC of rabbits

Figure 1 Effects of rhubarb decoction on the increase of [Ca²⁺]i induced by CaCl₂ in isolated rabbits intestinal mucosal INT-MNC. ^aP ＜ 0.05, ^bP ＜ 0.01 vs control. ● Control (n = 8); △ Rhubarb decoction 1 mg/L (n = 5); ▲ Rhubarb decoction 2 mg/L (n = 5).

Figure 2 Effects of SEN on the increase of [Ca²⁺]i induced by CaCl₂ in isolated rabbits intestinal mucosal INT-MNC. ^aP ＜ 0.05, ^bP ＜ 0.01 vs control. ● Control (n = 6); △ SEN 0.021 mmol/L (n = 5); ▲ SEN 0.084 mmol/L (n = 5).

Figure 3 Effects of EMD on the increase of [Ca²⁺]i induced by CaCl₂ in isolated rabbits intestinal mucosal INT-MNC. ^aP ＜ 0.05, ^bP ＜ 0.01 vs control. ● Control (n = 10); △ EMD 9.2 μmol/L (n = 10); □ EMD 18.5 μmol/L (n = 8); ■ EMD 37 μmol/L (n = 7).
