Antiplatelet Effectivity between Aspirin with Honey on Cardiovascular Disease Based on Bleeding Time Taken on Mice

BACKGROUND: The prevalence of cardiovascular disease (CVD) and its mortality continues to increase. Various studies have shown aspirin can reduce CVD mortality but has adverse side effects. Research on a comparison between aspirin and honey has not been done, but both have antiplatelet effects. AIM: This study is aimed to prove the antiplatelet effects on honey and compare the antiplatelet effects of aspirin with honey based on the bleeding time in mice. METHODS: This study is a true experimental design with a post-test only control group using 32 male mice, Double Ditsch Webster, ± 3 months old, the weight of 20-30 g, divided into 4 groups. Consisting of a negative control group (placebo), aspirin and honey. The suspension has given orally for 12 days using the probe. The research was conducted at the Laboratory of Pharmacology Department of Pharmacology and Therapeutics Faculty of Medicine, the University of North Sumatra in September until December 2015. The data collected was bleeding time in mice. Data analysed by Shapiro Wilk test, Kruskal Wallis and Mann Whitney. RESULTS: The mean bleeding time was a placebo (102.88 seconds), aspirin (369.38 seconds) and honey (304.63 seconds). Mann Whitney test showed significant results in the aspirin and honey groups against the control group (placebo) with p = 0.001. There were no significant differences in the aspirin group against honey (p = 0.172). Honey has an antiplatelet effect in mice. The mean bleeding time in mice given honey is longer or closer to the mean bleeding time in the aspirin group. CONCLUSION: The results could be used as a basis for further research to determine its use in humans with cardiovascular disease.

Malaria is an infectious disease caused by the Plasmodium sp. parasite. In 2017, malaria has reached 219 million cases. The decline of parasitemia index indicates a lower degree of infection in malaria patients. Goat milk and goat milk yogurt as immunomodulators have the potential to reduce parasitemia index. This study was aimed to determine the effect of goat milk and goat milk yogurt on the index of parasitemia in malaria-infected mice. This research was a true experimental study with a post-test only group design. A total of thirty-five female Balb/c mice was divided into the following groups: a (negative control group), b (malaria), c (malaria, Dihydroartemisinin/piperaquine (DHP) drug), d (malaria, goat milk), e (malaria, goat milk, DHP), f (malaria, goat milk yogurt), and g (malaria, goat milk yogurt, DHP). Inoculation dose of Plasmodium was 107 /0.2 mL. The intervention was studied for 24 days. Parasitemia index data was collected on the seventh day post-inoculation. The dose of goat milk and goat milk yogurt given was 0.5 mL/20 g BW. Data were analyzed using Kruskal-Wallis with Mann-Whitney post-hoc test. The results showed a significant decrease in the parasitemia index (p<0.05). The mean parasitemia index in each group were: 0% (a); 13.9% (b); 0.60% (c); 4.68% (d); 3.74% (e); 3.66% (f); 0.82% (g). The group that exhibited effective reduction of parasitemia index were group c and g. Goat milk yogurt (f) was more effective in decreasing the parasitemia index than goat milk (d). Giving goat milk yogurt can be considered an additional therapy for the treatment of malaria.

Dental procedures produce a large amount of spatter and aerosols that create concern for the transmission of airborne diseases, such as Covid-19. This study established a methodology with the objective of evaluating new associated strategies to reduce the risk of cross-transmission in a health environment by simulating spread of potentially contaminated dispersion particles (PCDP) in the environment. This crossover study, was conducted in a school clinic environment (4 clinics containing 12 dental chairs each). As a positive control group (without barriers), 12 professionals activated at the same time the turbine of dental drill, for one minute, with a bacterial solution (Lactobacillus casei Shirota, 1.5x108 CFU/mL), which had been added in the cooling reservoir of the dental equipment. In the experimental groups, the professionals made use of; a) an individual biosafety barrier in dentistry (IBBD) which consists of a metal support covered by a disposable PVC film barrier; b) a Mobile Unit of Disinfection by Ultraviolet-C, consisting of 8 UV lamps-C of 95W, of 304μW/cm2 of irradiance each, connected for 15 minutes (UV-C) and; c) the association between the two methods (IBBD + UV-C). In each clinic, 56 Petri dishes containing MRS agar were positioned on the lamps, benches and on the floor. In addition, plates were placed prior to each test (negative control group) and plates were also placed in the corridor that connects the four clinics. In the groups without barrier and IBBD + UV-C the passive air microorganisms in Petri dishes was also evaluated at times of 30, 60, 90 and 120 minutes after the end of the dental’s drill activation. The mean (standard deviation) of CFU of L. casei Shirota for the positive control group was 3905 (1521), while in the experimental groups the mean using the IBBD was 940 (466) CFU, establishing a reduction on average, of 75% (p<0.0001). For the UV-C group, the mean was 260 (309) CFU and the association of the use of IBBD + UV-C promoted an overall average count of 152 (257) CFU, establishing a reduction on average of 93% and 96%, respectively (p<0.0001). Considering these results and the study model used, the individual biosafety barrier associated with UV-C technology showed to be efficient strategies to reduce the dispersion of bioaerosols generated in an environment with high rate of PCDP generation and may be an alternative for the improvement of biosafety in different healthy environment.

Abstract Abstract 3357 In this present study in beagle dogs, we evaluated the antithrombotic efficacy of Pulaimab, the chimeric monoclonal antibodies SZ21-F(ab)2 fragments against platelet glycoprotein (GP) β3, in a modified Folts model. The Folts model is widely accepted to be effective and clinically relevant for testing potential anti-thrombotic agents, in this model the cyclic flow reductions (CFRs) are caused by platelet dependent thrombi that form under high-shear conditions at injured stenosed sites of an artery. Thirty beagle dogs of either sex, weighing 7.5 to 14 kg, were randomly divided into five groups of six (three females and three males), the details were following: negative control group (injected normal saline), positive control group (injected 0.2mg/Kg of Reopro), and three experimental groups [injected 0.2, 0.4, 0.8 mg/Kg of SZ21-F(ab)2, respectively]. A dose range from 0.2 to 0.8 mg/kg of Pulaimab significantly reduced the CFRs by 21–73%, without reduction of platelet numbers and prolongation of the bleeding time. Ex vivo ADP-induced platelet aggregation was equally reduced. The present study demonstrates that the inhibition of platelet GP αIIbβ3function by SZ21-F(ab)2 is a powerful intervention to prevent platelet thrombus formation in injured arteries without thrombocytopenia and prolongation of the bleeding time. We therefore conclude that F(ab)2 fragments of inhibitory anti-GPβ3 antibodies may be useful compounds to prevent thrombosis. Disclosures: No relevant conflicts of interest to declare.

Background. There are numerous medicinal plants including the leaves of Grewia ferruginea used as traditional medicine for the treatment of constipation. This study was conducted to evaluate the laxative activity of the leaves of G ferruginea. Methods. The laxative activity of the leaves of G ferruginea was tested using 3 models: laxative activity, gastrointestinal motility, and gastrointestinal secretion tests. The effect of the plant extract on mean number of feces, fecal water content, ratio of intestinal distance traveled by the charcoal meal and intestinal fluid accumulation were evaluated and analyzed. Results. Significant increase was observed in the mean weight of wet fecal matter at 200 (1.00 ± 0.03 g, P < .05) and 400 mg/kg (1.01 ± 0.02 g, P < .01), relative to loperamide constipated negative control group. Similarly, percent fecal water content was significantly improved in extract treated groups at 100 mg/kg (52.10% ± 2.04%, P < .05), 200 mg/kg (54.02% ± 2.15%, P < .01), and 400 mg/kg (54.25% ± 2.50%, P < .01) compared with the negative control group. The gastroinestinal transit ratio was also significantly increased with 200 mg/kg ( P < .01) and 400 mg/kg ( P < .001) of the extract relative to the constipated negative control. The crude extract showed significant increase in intestinal fluid accumulation at 200 mg/kg (0.48 ± 0.07 g, P < .05) and 400 mg/kg (0.51 ± 0.08 g, P < .01) compared with the negative control. Conclusion. The results of the present study indicated that 80% methanol extract of the leaves of G ferruginea possessed significant laxative activity. As such, this study corroborates the traditional claim of using G ferruginea in the treatment of constipation.

ABSTRACTMosquitoes are type of insect that acts as a disease vector. One of them is Culex sp mosquitos which their existence is many around us. In Indonesia there are still a lot of disease cases that caused by Culex sp mosquitos, one of them is filariasis disease. The efforts to control thecurrent population of Culex sp mosquitoes mostly use chemical insecticides. The control becomes difficult because of the resistance to chemical insecticides and adversely affects the environment. This study aims to determine the potential of jackfruit leaf extract as biolarvasida against Culex sp. The type of this study was post test onlycontrolled group design, using 625 larvae Culex sp instar III, divided into 5 groups (negative control group, 0.25% extract, 0.50% extract, 0.75% extract, extract and 1% extract). Observation was performed 24 hoursafter the treatment and counted the number of larvae death.The data were analyzed by Kruskal Wallis test followed by Post Hoc Mann-Whitney U test to determine the killing power of leafy leaf extractusing Probit analysis. The results of data analysis in this study were thedeath rate percentage of larvae after 24 hours treatment was 0% incontrol, 44% in 0.25%extract, 52% in0.50% extract, 60% in 0.75%extract,while in the extract group of 1%, the number of larval deaths was 72%. Itobtained results with significant differencein some treatment groups thatwere concentrations of 0.25% - 1%. Probit analysis showed that LC50 wasat 0.382% concentration.From results of the studyit can be concluded that jackfruit leaf extract(Artocarpus heterophyllus Lamk) was potential as Culex sp mosquitobiolarvacide. So it is necessary to conduct further research on the effectsof compounds that contained in other plant parts such as flowers, stemsand roots which will be expected to have a function asbiolarvasida.Keywords: Leaf Jackfruit, Biolarvasida, Mosquito Culex sp
