RESUMEN
Purpose: To prove the effect of Miana (M), Quercetin (Q), and the combination as an anti-inflammatory agent and Cefixime (C) as an antibiotic in Balb/c mice infected with Salmonella enterica serovar Typhi (S. Typhi) and related to the dynamics of NF-κB mRNA expression and NF-κB protein levels. Methods: A cohort study on male Balb/c mice with subjects consisted of 8 groups with 5 each group by administration of M, Q, M + Q, M + C, Q + C, M + Q + C, C only and sterile distilled water group as negative control. The statistical significance of the difference group was defined as P values less than 0.05. Results: Decreased mRNA expression of NF-κB, NF-κB protein levels, and bacterial load after administration of M + C, Q + C, or M + Q + C showed significant differences when compared to the negative control. The decline in NF-κB was stronger when M + Q + C was given compared to M, Q, M + Q, or C only. Conclusion: The effects of NF-κB suppression appear to be the same between the administration of M, Q and the M + Q when C added. However, the suppression of NF-κB was not significant without adding C.
RESUMEN
Background: Chronic obstructive pulmonary disease (COPD) is characterised by persistent and progressive airflow limitations. The study aimed to determine the relationship between eosinophil values in patients with stable and exacerbated COPD, and the relationship of eosinophil values with two drug regimens used as maintenance therapy in stable COPD. Materials and methods: This cross-sectional study and the variables used in this study were eosinophil counts in stable and exacerbated COPD patients. Results: Eighty-three patients with stable and exacerbated COPD were included. Stable COPD (63.9%) was predominant, with the highest degree of symptoms in group A 18 patients (34%) and Global Initiative for Chronic Obstructive Lung Disease (GOLD) 2; 35 patients (66%). The degree of COPD exacerbation was dominated by Type II COPD 15 patients (50%). Eosinophil counts in patients with stable COPD were less than 100 cells/mm3 37 patients (44.6%), while in patients with COPD exacerbation, it was greater than 100 cells/mm3 with a total of 30 patients (36.1%). Long acting muscarinic antagonist class of drugs was the most used treatment as maintenance therapy in stable COPD 34 patients (64.2%). Conclusion: The eosinophil counts in patients with COPD exacerbation were significantly higher than those in patients with stable COPD. The provision of maintenance therapy in the long acting ß-2 agonist + inhaled glucocorticosteroid group of stable COPD patients was generally provided to COPD patients with eosinophil values greater than 100 cells/mm3, and the provision of long-term maintenance therapy in stable COPD patients was generally given to COPD patients with eosinophil values less than 100 cells/mm3.
RESUMEN
An accurate diagnosis of COVID-19 is essential for pandemic control and for establishing adequate therapeutic strategies to reduce morbidity and mortality. COVID-19 infection replicates in macrophage cells and affects the immune system. Natural resistance-associated macrophage protein-1 (NRAMP-1) carries cation ions, such as Fe2+, Zn2+ and Mn2+, and plays an essential role in the immune system to infection with micro-organisms. In addition, the function of NRAMP-1 is to limit the replication of pathogens by changing the phagosomal environment. Levels of NRAMP-1 protein are based on death, comorbidities and clinical symptoms of COVID-19 patients and it is possible for the soluble protein NRAMP-1 level to be used as an additional biomarker for forensic and medicolegal related COVID-19 cases and prosecutions from patients and families. Methods: Determination of NRAMP-1 protein levels using the enzyme link-immunosorbent assay technique in death, had comorbidities and severity of clinical symptoms of COVID-19 patients. Results: Of the 62 patients who received treatment, 10 patients died with an average NRAMP-1 level of 650 ng/ml and 52 patients who survive with an average NRAMP-1 level of 1065.26 ng/ml. The results of the study also found that 34 patients had comorbidities with an average NRAMP-1 level of 838.82 ng/ml and 28 patients without comorbidities with an average NRAMP-1 level of 1191.92 ng/ml. Based on the severity of clinical symptoms in survive patients, 10 patients with mild were found with an average NRAMP-1 level of 984.31 ng/ml, with moderate in 31 patients with an average NRAMP-1 level of 1104.71 ng/ml and severe in 11 patients with an average NRAMP-1 level of 1027.71 ng/ml. Conclusions: NRAMP-1 protein levels were significantly lower in COVID-19 patients who died and had comorbidities.
RESUMEN
Pneumonia is one of the most common infections caused by the bacterium Klebsiella pneumoniae. During the initiation of an infection, the immune system recognizes the pathogen through the release of high mobility group box 1 (HMGB1), thereby triggering the inflammation process. Miana has demonstrated potent inhibitory effects on the inflammatory process during infection in animal models. The aim of this study was to determine the effect of Miana leaf extract on mRNA HMGB1 expression in Balb/c mice infected with K. pneumoniae. Methods: This study comprised a cohort experiment using 20 Balb/c mice divided into four groups. Balb/c mice in each group were intraperitoneally injected with K. pneumoniae. Group 1 was given a placebo; Group 2 was given Miana; Group 3 was given levofloxacin; and Group 4 was given both levofloxacin and Miana. The levels of mRNA HMGB1 expression were measured using real-time PCR before, during, and after the infection as well as after the treatments. Results: The initial examination results showed that the average level of mRNA HMGB1 expression was 5.51 fc. The mRNA HMGB1 expression in mice after being challenged with K. pneumoniae was 9.64 fc. Group 1 that was given a placebo had a mean mRNA HMGB1 expression level of 14.99 fc. Group 2 that was given Miana had a mean mRNA HMGB1 expression level of 13.95 fc. Group 3 that was given levofloxacin had an average mRNA HMGB1 expression level of 6.45 fc, and Group 4 that was given levofloxacin and Miana together had an average mRNA HMGB1 expression level of 5.59 fc. Conclusion: Miana (Coleus scutellarioides (L.) Benth) increased mRNA HMGB1 expression at the initial administration via regulation of the immune system. Administration of Miana following K. pneumoniae infection inhibited the increase in mRNA HMGB1 expression. Treatment with levofloxacin reduced the level of mRNA HMGB1 expression, and the effect was optimized by the administration of Miana leaf extract as a supplement.
RESUMEN
In this article, a valuable approach utilizing the relationship between select physical water and soil characteristics and geoelectrical resistivity data was used to recognize and trace groundwater contamination by using the geoelectrical resistivity data of a landfill area. It can reduce uncertainty in geoelectrical resistivity interpretation. By interpreting and calibrating the resistivity model with the lithology and physical characters of water samples, it was possible to identify the unique paths of landfill leachate that occurred throughout a shallow aquifer. The water physical property analysis showed that the landfill area was contaminated by a relatively high amount of total of dissolved solids (TDSs). A scatter plot of TDS values and directly measured resistivity showed that resistivity decreased with increasing TDSs. The movement direction of the landfill leachate in the aquifer system was clearly observed in a depth slice of the resistivity distribution. The aquifer is considered to be contaminated starting from the landfill zone and extending to the northeastern part of the study area.
