Abstract

Clinical manifestations of dengue virus infection vary from unspecified fever, dengue fever (DF) and dengue hemorrhagic fever (DHF). The fundamental difference in the diagnosis between DF and DHF is plasma leakage, hypotension, thrombocytopenia and hemorrhagic diathesis in DHF. The objectives of the study were to determine the lowest platelet, haematocrit increase, and TNF-α levels in DF and DHF patients as an indication of severity of dengue virus infection. The cross-sectional study was conducted by taking 54 blood samples of patients aged 26-45 years who were infected by dengue virus and grouped into two groups: DF patient group (27 blood samples) and DHF group (27 blood samples). The lowest platelets and hematocrit rise were determined by Hematology Analyzer and the TNF-α levels were determined by ELISA. The data obtained were statistically analyzed by independent Mann-Whitney test. The results showed that the lowest mean platelet counts of DF patients were significantly (p <0.01) higher than those of DHF patients. The mean hematocrit increase in DF patients was significantly (p <0.01) lower than that of the DHF patients and the mean TNF-α levels of DF patients were significantly (p <0.01) lower than the DHF patients. Based on the results of this study it can be concluded that the lowest platelets, hematocrit increase and TNF-α levels are an indication of the severity of dengue virus infection.

Abstract

Aloe vera (Aloe barbadensis Miller) contains anthraquinone compounds, flavonoids and saponins which are thought to have antibacterial effects so as to inhibit bacterial growth. The purpose of the study was to determine the inhibitory power of Aloe barbadensis Miller on the growth of Staphylococcus aureus bacteria. The pure experimental study was conducted with The Randomized Posttest Only Control Group Design using six (6) treatments, namely aloe vera extract with a concentration of 25%, 50%, 75%, 100%, Chloramphenicol 30 mcg antibiotics as a positive control, and sterile aquadest as a control negative for Staphylococcus aureus bacteria grown on Mueller Hinton media. After being treated, it was incubated for 24 hours and measured its inhibitory power. The growth inhibition data of Staphylococcus aureus bacteria in the form of inhibition zone diameter was analyzed statistically by Kruskal Wallis test, at the level of confidence α = 0.05. The results showed that the average inhibitory effect of Aloe vera extract on the growth of Staphylococcus aureus bacteria in concentrations of 25%, 50%, 75% and 100% were 0 ± 0 mm; 7.125 ± 0.1250 mm; 8.375 ± 0.23936 mm; and 9.0 ± 0.40825 mm. Based on the results of the study concluded that aloe vera extract can inhibit the growth of Staphylococcus aureus bacteria. The higher the concentration of Aloe vera extract the greater the inhibitory effect on the growth of Staphylococcus aureus bacteria.

Abstract

This study aimed to determine the types of STH that contaminate cabbages in the Tabnan traditional market, and to determine the effect of leaf position and washing method on STH contamination. This study using completely randomized experimental design. The research was carried out in the Tabanan traditional market. A total of 28 cabbage were taken in 10 traditional markets in Tabanan Regency. Laboratory tests were conducted to determine the presence of STH were carried out by 0.2% NaOH sedimentation technique and centrifugation. The STH examination method uses the Kato-Katz method. The results of the study found soil transmitted helminth larvae on the strands of the outer cabbage leaves without washing and stagnant water washing. STH larvae found were filariform larvae of Necator americanus and Ancylostoma duodenale on the outer strands without washing. Whereas in the outermost strands with stagnant water washing only filariform larvae of Necator americanus were found. When compared to the average number of three replications, in the outermost cabbage strands without washing found more larvae compared to stagnant water washing. In the outermost strands by washing the running water there was no STH contamination nor did the middle strands and inner strands, either without washing, washing in stagnant water or washing water flow. However before consumption, cabbage should be washed with running water, to avoid infection with STH through the oral route.
