Abstract

Background: Indian almond (Terminalia catappa) is used as an alternative medicine by the community to treat various diseases. However, limited research has been conducted on the subchronic toxicity of Indian almond water extracts on the liver. Present study aimed to determine the subchronic toxic effects of Indian almond leaf water extract on the liver histology of mice and to evaluate the safe dose of Indian almond leaf water extract with various doses (125, 250, 500, 750 and 1000 mg/kg). Methods: In total of 33 male mice were randomly divided into 11 groups, each group consisting of three mice as replication. For 30 days, mice in five treatment groups were orally treated every day with water extracts of green Indian almond leaf while other five groups were given water extracts of brown Indian almond leaves and compare with control group. At the end of day 30, all mice were sacrificed, and hepar was taken out for histological preparations. The histopathological changes in the liver was observed and assessed based on histological damage in the term of degeneration and necrosis. Results: The administration of green and brown Indian almond water extract at doses of 125, 250, 500, 750 and 1000 mg / kg BB showed a toxic effect on the liver of mice. The toxic effect was due to the high doses, causing a cell swelling damage and increased liver necrosis. Conclusion: Indian almond leaf water extract can cause toxic effects on the liver of mice at the doses implemented.

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: 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.

Abstract

Background: A misconception is a form of error in scientific knowledge that is believed to be accurate. As a result, someone who has a misconception of something will reject scientific truth and will hinder the assimilation of new knowledge. The purpose of this study was to identify misconceptions that occur in students regarding the topic of blood classification. Methods: The survey method research was conducted on 97 students scattered in Malang and Tulungagung, Indonesia. The data analysis technique uses coding for categorization into four categories: conceptual understanding, partial understanding, misconception, and not understanding the concept. Results: The results showed that misconceptions occurred in all sub-topics of blood classification. Misconceptions were found in the concept of blood plasma (2.1%), white blood cells (6.2%), thrombocytes (17.5%), and blood classification system (8.2%). Misconceptions occur due to several misunderstandings of students such as red blood cells that play a role in transporting nutrients, haemoglobin only binds oxygen, and difficulty distinguishing between antigens and antibodies in determining blood groups, blood donation, and the impact arising from donations. Conclusion: The existence of misconceptions causes students' mastery of blood classification material to be hampered.
