Figure 2.

Effect of aqueous extract of the root bark of Morus alba L. (AMA) on secretion of in vivo airway mucin from rats exposed to sulfur dioxide. Rats were exposed to sulfur dioxide and effect of orally-administered AMA on secretion of in vivo airway mucin was investigated. Three independent experiments were performed and the representative data were shown. Each bar represents a mean±SEM from 5 rats. Concentration unit is mg/kg body weight. ^*Significantly different from control (p<0.05). ^†Significantly different from SO₂ alone (p<0.05). Dexa: dexamethasone; SO₂: sulfur dioxide.
