The Covid-19 infection has spread to almost all regions of Indonesia. The government has issued a health protocol policy for the public in carrying out their activities to minimize the transmission of covid-19. This study aimed to obtain an overview of public compliance behavior in implementing health protocols as an effort to prevent Covid-19. The questionnaire survey was conducted at one of the pharmacies in the Banjarsari area of Surakarta for the period 14-30 September 2020. The research subjects were determined by purposive sampling method. The questionnaire contains 16 statement items covering the domain of social distancing, use of masks, maintaining hygiene and hand washing, and cough etiquette. Respondent behavior was classified into 2 categories, namely compliance and noncompliance. Respondent characteristic data (gender, age, and occupation) were tested for their relationship with compliance behavior. This study involved 54 respondents who were dominated by women (68.52%), age range 36- 45 years (37.18%), and work as private employees (37.04%). A study on 54 respondents showed that 51.85% of respondents had complied with the implementation of health protocols. Community non-compliance was still high in the domain of maintaining hygiene and cough etiquette. Gender, age, and occupation were not significantly related to respondent behavior.
As one of the leading causes of death in worldwide, cervical cancer requires the effective therapies to reduce its mortality rate. One of the chemotherapy agents that frequently used in the treatment is cisplatin. However, due to drug resistance and its side effects, an agent that can be combined with cisplatin is needed. Parijoto fruit (Medinilla speciosa Reinw.ex.Bl) contains secondary metabolites compounds that have potential as anticancer. The study aims to determine the cytotoxic effect of methanol extract of Parijoto fruit calculated from the IC50 value and the synergicity of the combinational treatment with cisplatin evaluated from the Combination Index (CI) value and its cell viability by using MTT assay. Results showed that methanol extract of Parijoto fruit (MEP) performed cytotoxic effect on HeLa cell line with IC50 of 209.6 μg/mL while the value of IC50 of cisplatin against HeLa cells amounted to 12.8 μg/mL. The combination of 26.205 ppm (1/8 IC50) of MEP and 1.601 ppm (1/8 IC50) of Cisplatin performed synergistic effect on HeLa cell line with the CI value of 0.69. From the above results, it can be concluded that MEP is potential as co-chemotherapy agent based on the synergistic cytotoxicity effect with cisplatin.Keyword: cytotoxic, Medinilla speciosa, cisplatin, co-chemotherapy, MTT
Cisplatin is a chemotherapy agent in the treatment of cervical cancer. However, due to drug resistance and its side effects are much needed an agent that can be combined with cisplatin. Parijoto fruit (Medinilla speciosa Reinw.ex.Bl) have potential cytotoxic effect derived from natural ingredients. The study aims to determine the potential cytotoxic effects of ethyl acetate and n-hexane extract from Parijoto fruit calculated from the value of IC50 and the profile of these extract on normal cell. The determination of the cytotoxic effect of Parijoto fruit extract using MTT assay that the results can be read absorption by using ELISA reader. Data analysis is calculated by linear regression methods by using Microsoft Excel software. Results showed that ethyl acetate and n-hexane of parijoto fruit performed cytotoxic effect on HeLa cell line with IC50 respectively, 352,9 μg/mL; 904,7 μg/mL while the value of ethyl acetate and n-hexane of parijoto fruit performed cytotoxic effect on WiDr cell line with IC50 respectively, 554,9 μg/mL; 434,4 μg/mL. Data analysis showed that the cytotoxicity effect of nonpolar extract from parijoto fruit is include in the moderate cytotoxic category.
Wijayanti II, Budiharjo A, Pangastuti A, Prihapsara F, Artanti AN. 2018. Total phenolic content and antioxidant activity of ginger extract and SNEDDS with eel fish bone oil (Anguilla spp.). Nusantara Bioscience 10: 164-169. Aims of this study were to measure phenolic content of ginger (Zingiber officinale) and to observe the comparison of antioxidant activity between pure ginger extract and ginger extract in SNEDDS (Self Nanoemulsifying Drug Delivery System) with bone of eel fish oil (Anguilla spp.) as a conductor. Analysis was done based on IC50 value using DPPH (2,2 diphenyl-1-picrylhydrazyl) method and activity of Superoxide Dismutase (SOD) in vivo using Adrenochrome Assay. Determination of total phenolic content of ginger extract was measured by UV/Vis Spectrophotometric using Folin-Ciocalteau reagents then the absorbances were measured at wavelength 756 nm. Calculation of IC50 DPPH of the ginger extract and SNEDDS were measured using spectrophotometer UV/Vis at 517 nm wavelength. Measurements of SOD was based on the ability of SOD inhibit spontaneous auto reduction of epinephrine using Adrenochrome Assay at 12 male Wistar rats that divided into 4 treatment groups with 3 replicates for each group. Total phenolic content of ginger extract from 3 replications were 4,8519 ± 0,037 µg/mL equivalent with gallic acid standard solutions (GAE) or 485,1847 ± 3,7045 mgGAE/100 g dry weight. Antioxidant scavenging activity by DPPH assay of ginger was higher than SNEDDS. IC50 of ginger was 385.4 mg/mL, and IC50 of SNEDDS was 428.4 mg/mL. The result of descriptive analysis of Kruskal Wallis of SOD activity assay indicated significant differences between treatment groups (P = 0.001 (P <0.05)). SOD activity test performed in vivo showed that ginger extract made into SNEDDS system with eel fish oil used as the conductor has a significant influence compared with ginger extract group.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
