The effect of Etlingera elatior J. flower on the pulmo histology of white rat (Rattus novergicus L.) after cigarette smoke exposure

Abstract

Cigarette smoking is one of health issues that mainly harmed the lung due to its free radicals. Kecombrang (Etlingera elatior J.) is a medicinal plant known to have a high amount of antioxidant. This study aims to determine the effect of antioxidant in Etlingera elatior J. flower on the improvement of pulmonary histology of male white rats (Rattus novergicus L.) as the secondhand smoke (cigarette exposure). This research was conducted by experimental method with ethanol extract of Etlingera elatior J. flower and pulmonary organ of white male rats as the test materials. There were 25 white male rats that divided into 5 groups (Positive Control, Negative Control, P1: 30 mg/Kg, P2:60 mg/Kg, and P3:90 mg/Kg). The results were statistically analyzed using One Way ANOVA test and Duncan’s test. The results showed a decreased amount of damage at P1, P2 and P3 groups. The statistical analysis showed that Etlingera elatior J. flower extract had a significant effect (p <0.05) on the histological improvement in each group. Group P2 shows the lowest rate of damage that it can be concluded the most effective dose in repairing the damage to rat pulmonary histology due to exposure of cigarette smoke.
