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

Background: This study aimed to evaluate the growth ability of cassava mini stem cuttings with different node number and a variety of stem cutting shapes and their correlation with starch content in the stems at initial growth stages. Methods. In this study, the viability of cassava stem cuttings was identified in two type experiments i.e. mini-stem cuttings consisting 1 and 2 nodes and shape variation of single node mini-stem cutting. Parameters observed were shoots emergence period, number of sprouting cuttings, shoots number of individual stem cuttings, shoots height and number of leaves. In addition, starch histochemical test was also carried out on stems of young shoots and initial stem cuttings using Lugol's solution. Results. Both cassava stem cuttings consisting of 1 and 2 buds indicated the same survival rate of 100%. 1 bud stem cuttings with different shapes showed different survival rate, i.e. 60-80% for semicircular and fully circular cuttings and 30-40% for box shape cuttings. The difference in survival rate with different stem size is probably related to the availability of the amount of starch to support shoots growth. Observations at week 3 after planting generally showed that the stem cuttings with 2 buds were higher than those of stem with 1 bud. Conclusion: There were differences in the scores on the starch content test qualitatively with Lugol staining, in various parts of the plant originating from 1 bud and 2 bud cuttings which may indicate a breakdown of starch during shoot development.

Abstract

Background: Gonad differentiation in some teleostei is a critical phase of gonad development. Gonad differentiation in some fish such as the tilapia group is influenced by environmental factors, namely temperature. The aim of this study was to determine the differentiation process of Nilem fish gonads (Osteochilus vittatus) under the influence of temperature. Methods: One day after fertilization (days postfertilization/dpf) fish were exposed to different medium temperature ranges, namely: 28-29 oC, 30-31 oC, 32-33 oC, and room temperature as a control for 35 days. The percentage of fish survival was calculated on the 35th day by calculating the number of surviving fish divided by the total number of fish in 1 tank times 100%. Thirty fish in each treatment were measured for body length at day 10 dpf and day 35 dpf to determine fish growth. Six fish 35 dpf from each treatment were fixed in 70% alcohol for making histological preparations using the paraffin method, Haematoxylin-Eosin staining. Fish survival data growth data in the form of fish length were analyzed using Anova. Gonadal differentiation data were analyzed descriptively. Results: There was no significant difference in the growth of fish in all treatment and control groups. The average survival rate of fish in all treatment and control groups was 100%. Observation of the gonads showed that the gonads were not differentiated in all treatment and control groups. Conclusion: The room temperature range up to 33 oC supports the growth of Nilem fish with gonad development in the indifferent gonad stage.
