Abstract

Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by Dengue Virus through Aedes aegypti mosquito vector with rapid deployment and be able to cause death.. The use of chemical insecticides to suppress cases in the comunity when used continuously for a long time have a detrimental impact, because of that it is necessary to find an alternative way wich is form of botanical larvacides, such as cinnamon bark (Cinnamomum burmanni). The aim of this research was to find out the comparison of larvacidal effects of ethanol extracts of cinnamon and temephos against Aedes aegypti mosquito larvae. This was the experimental research with three repetitions that each concentration was containing 10 larvae. The analysis of research result use the analysis regresi probit wich was gotten LC50 was 85,727 ppm, LC90 was 135,180 ppm, LC99 was 175,497 ppm and temephos with 1 ppm concentration kills 100% larva. It can be concluded that temephos was better than the extract of cinnamon as larvacide.Keywords: larvacidal effects, Cinnamomum burmanni, Aedes aegypti, temephos

Abstract

Background: Pulmonary hypertension can occur in stable chronic obstructive pulmonary disease (COPD) patients despite its unknown etiology or as a complication associated with other processes. Pulmonary hypertension was divided into five broad categories, including processes with common pathogenic mechanisms. The true incidence of pulmonary hypertension in COPD is unknown, as no systematically performed screening method can be widely used in COPD patients, while the mortality rate or complications from COPD are still very high. Method: This study method was a cross-sectional study. This study was conducted on stable COPD patients who came to the pulmonary department at Arifin Achmad General Hospital to assess its association with the risk of pulmonary hypertension. Results: This study involved 77 research subjects with the highest age <65 years (64.9%) with male gender (84.4%), airflow limitation degree GOLD II (moderate) (50.6%), severe Brinkman Index (76.6%), comorbid hypertension (7.8%), Asymmetric Dimethylarginine (ADMA)0 inflammatory marker including low-risk category (77.9%) and mild echocardiographic interpretation (75.3%). The Association of COPD severity was significant to the risk of pulmonary hypertension, the degree of airflow limitation (P=0.0001) and echocardiography interpretation (P=0.0001). At the same time, there was no significant association with ADMA levels (P=0.239). The Brinkman Index of smokers (P=0.006) was an important risk factor for pulmonary hypertension. Conclusion: There was an association between COPD severity, echocardiographic interpretation and smoking status based on the Brinkman Index and the risk of pulmonary hypertension.
