Abstract

Background: Electric cigarette is a type of cigarette that change the liquid containing nicotine and other ingredients in the form of steam. This research aimed to identify the effect of exposure to e-cigarette smoke towards the thickness of bronchioles mucosa and the alveolar septa on male Balb'C mice (M. musculus). Methods: This research was an experimental design used 24 male divided into four groups, i.e., control dan three treatment groups. Treatment groups were given different volume of e-cigarettes liquid, i.e., 1 ml; 2 ml; and 4 ml. The exposure of e-cigarette was done in 4 weeks, respectively. Results: Electric cigarette exposure with different fluid volumes leads to an increase in the bronchioles mucosa's thickness and the alveoli septa. Increasing the volume of fluid used results in an increase in bronchioles mucosal thickness, but decreases the alveoli septa's thickness, resulting in destruction and dilatation of the alveoli. Conclusion: Exposure to e-cigarette smoke with a liquid volume of 1 ml affects the increase in the average thickness of the bronchial mucosa and alveoli septa. An increase in the average thickness of the bronchioles mucosa occurs along with increased fluid volume in exposure to e-cigarette smoke.

Abstract

Research on the toxicity of n-hexane extract of Albizia falcataria sawdust against Hypothenemus hampei has been conducted. The method of research was contact method. The concentrations used in the experiment were control (aquadest); 0.25%; 0.5%; 1%; 2%; and 4%. Every concentration was sprayed on the female imago. Observations were performed 120 hours after treatment. The results showed that there was an effect of the length of observation time and concentration on the mortality of H. hampei (GLM Test α= 5%). The time of observation and concentration of A. falcataria sawdust n-hexane extract has positive correlation on H. hampei mortality. Therefore, the longer the treatment time, the more H. hampei mortality is increased. The mortality of H. hampei also increased with increasing concentration given. At a concentration of 4%, extract of A. falcataria sawdust has high toxicity which causes the highest mortality (> 92%).
