Effect of Propolis Preparations on Transepithelial Electrical Potential, Resistance, and Ion Transport in In Vitro Study

Figure 6

The resistance for I, II, and III group during RH₁, RH₂, B, and AB stimulation. This figure shows arrangement the electrical resistance for first and second simulation by Ringer solution (stimulation RH₁, stimulation RH₂), stimulation by bumetanide (stimulation B), and stimulation by amiloride with bumetanide (stimulation AB). Abbreviations. p < 0.001. I: long-term incubation in 1 ml ethanol extract of propolis dissolved in 100 ml water, II: undisturbed ion transport, III: long-term incubation in propolis ointment, (RH₁): transepithelial resistance for first Ringer solution stimulation, (RH₂): transepithelial resistance for second Ringer solution stimulation, and (B, AB): transepithelial resistance for bumetanide solution and mixture of amiloride with bumetanide solution stimulations.
