<![CDATA[Ciplukan leaves contain alkaloid compounds and exhibit pharmacological activity as bronchodilators. Bronchodilators are utilized in chronic inflammatory respiratory conditions such as asthma, involving various cell types such as mast cells, eosinophils, and epithelial cells. The objective of this study was to evaluate the effectiveness of administering Ciplukan leaf infusion as a bronchodilator. A total of 24 Sprague Dawley rats were divided into 6 groups: normal control (K1), negative control (K2), positive control (K3), 200 mg/kg BW dose (K4), 400 mg/kg BW dose (K5), and 800 mg/kg BW dose (K6). On days 1 and 8, rats were sensitized with 0.35 mg OVA + 1 mg AlOH3 in 0.9% NaCl (i.p). On days 15, 17, and 19, rats were re-sensitized with inhaled OVA. From day 20 to 28, K1 and K2 received no treatment, K3 received 2 mL/day of salbutamol, and the dose groups were administered 2 mL/day of Ciplukan leaf infusion; all treatments were carried out simultaneously. On day 29, rats were dissected, and their lung organs were collected for histopathological preparation. Research findings revealed a reduction in bronchiolar epithelial thickness across groups in the following order: 495.05; 584.95; 334.69; 421.70; 482.81; 484.95 µm. The sequential lung eosinophil counts were 19; 44; 37; 23; 17; and 27, and mast cell counts were 9; 22; 13; 15; 13; and 7. Statistical analysis demonstrated significant differences at the 200 mg/kg BW dose for the parameters of bronchiolar epithelial thickness and eosinophil count, as well as significant differences in mast cell counts at the 800 mg/kg BW dose and negative control group.]]>
