The Relationship Between Total IgE, Symptom Duration, VAS Scores, and Danyoung Classification in Allergic Rhinitis
Get PDFAllergic Rhinitis (AR) is an inflammatory condition of the nasal mucosa triggered by allergies, with total IgE often used as a biomarker to assess disease severity. Objective: To analyze the relationship between total IgE levels, symptom duration, Visual Analog Scale (VAS) scores, and Danyoung Classification in AR patients. Methods: A cross-sectional observational analytical study was conducted on 73 patients at the Allergy-Immunology Clinic of Dr. Saiful Anwar General Hospital. Total IgE levels were measured using the ELISA method, while VAS and nasal mucosa classification were assessed through anamnesis and nasoendoscopy. Results: The study showed68.5% of patients had IgE levels above 100 IU/ml, with an average of 982.97 IU/ml. Although higher IgE levels were often found in AR patients, there was no statistically significant correlation between IgE levels and Danyoung classification (significance value 0.924). The correlation test showed a coefficient of -0.11, indicating a negative correlation, but it was not statistically significant. Conclusion: The nasal mucosa condition in patients with high IgE levels does not always reflect severe inflammation. In addition to IgE levels, external factors such as exposure to pollutants and cigarette smoke also play a role in the condition of the nasal mucosa. Therefore, while high IgE levels often indicate allergic reactions, this study found no significant relationship between IgE levels and AR severity
Effect of Prolonged Dehumidification on the Chemical Properties of Crassiacarpa and Mangium Honey
Get PDFHoney is a natural substance bees produce from nectar, flower sap, or liquid collected from living plant parts. The honey undergoes bee modification and binding before being stored in hexagonal combs. Effective dehumidification is crucial for enhancing honey quality and extending its shelf life. This study aimed to evaluate the effects of prolonged dehumidification time, honey type, and their interaction on the quality of Crassiacarpa and Mangium honey and to determine the optimal dehumidification treatment to meet the SNI 8664-2018 standard. A factorial Completely Randomized Design (CRD) with three replications was employed. Two liters each of Crassiacarpa and Mangium honey were placed in trays with a thickness of ±2 cm and dehumidified at 25°C and 40% humidity for 24, 48, 72, and 96 hours. Following dehumidification, the honey was analyzed for moisture content, total acidity, pH, and sensory attributes (taste, color, aroma, texture). Data were analyzed descriptively. The results demonstrated that dehumidification time significantly impacted moisture content, total acidity, and pH. Honey type significantly affected moisture content and pH. The interaction between dehumidification time and honey type significantly affected pH. The optimal treatment for both honey types was dehumidification for 96 hours, which resulted in honey that met the SNI 8664-2018 standard
The Effect of Methanol Seed Kernel Extract of Mangifera Indica on Guinea Pig Tracheal Smooth Muscles
Get PDFMangifera indica, commonly known as mango, holds a revered position in traditional medicine for the numerous health benefits derived from different parts of the plant. The purpose of this study was to investigate the effect of methanol seed kernel extract of Magnifera indica on isolated guinea pig trachea. The acute toxicity profile was first evaluated as well as its phytochemical screening before exposing various concentrations of the methanol seed kernel extract to acetylcholine (Ach)-precontracted guinea pig tracheal rings. From the results, a dose of 5000mg/kg of the extract did not produce any form of toxicity. The presence of tannins, flavonoids and cardiac glycosides was revealed which probably fuels the medicinal properties of the seed kernel. Exposure of acetylcholine pre-contracted tracheal rings to different concentrations of the methanol kernel extract, resulted in a shift of the Ach dose response curve to the right but without achieving any maximum relaxation. There was no observed IC50 but rather an IC30 concentration was observed around 0.0013M. However, the observed minimal relaxation of Ach pre-contracted rings was not statistically significant (p>=0.5). It is possible that the observed minimal relaxation potential of the kernel extract coupled with its reported anti-inflammatory properties boosts its application in the relief of bronchial asthma claimed in ethnomedicine
Formulation and Characterization Tests of SCOBY Kombucha Gel
Get PDFThe wound is the damage to body tissues caused by various factors such as accidents, sharp object scratches, etc. Proper care is necessary to accelerate the wound healing process. Topical medications, such as gel preparations, are commonly used for wounds. Kombucha SCOBY is believed to contain bioactive compounds that can accelerate the wound healing process, making it a potential active ingredient in gel preparations. This research aims to determine the characteristics of kombucha SCOBY gel with various concentration variations. SCOBY is obtained from kombucha fermentation using green tea, sugar, and kombucha culture. Preparing kombucha SCOBY gel involves using carbomer 940, methyl paraben, triethanolamine, glycerin, and SCOBY kombucha. The concentration variations of kombucha SCOBY gel include 0%, 2%, 4%, 8%, 10%, and 12%. Each formula undergoes physical characteristic tests including an organoleptic test, hedonic test, homogeneity test, pH test, spreadability test, and adhesiveness test. Data obtained after physical characteristic tests of the gel preparations are analyzed descriptively. Based on the conducted research, it was found that kombucha SCOBY gel preparations with concentration variations of 0%, 2%, 4%, 8%, 10%, and 12% exhibited different characteristics. The higher the gel concentration, the more acidic the gel's aroma, the more liquid the texture, and the more intense the color. SCOBY added to the gel preparation can increase the pH value, adhesiveness, and spreadability of the gel
In Vitro Evaluation of the Antibacterial Properties of Lime Mistletoe (Dendrophthoe petandra (L.) Miq.) Extract Against Escherichia coli
Get PDFThe increasing prevalence of antibiotic-resistant bacteria necessitates the exploration of alternative antimicrobial agents derived from natural sources. This study aimed to evaluate the in vitro antibacterial activity of lime mistletoe (Dendrophthoe petandra (L.) Miq.) extract against Escherichia coli ATCC 25922 using the disc diffusion method. Extract concentrations of 20%, 40%, 60%, 80%, and 100% were prepared alongside negative (distilled water) and positive (Cefadroxil) controls. Nutrient Agar (NA) media were inoculated with E. coli and discs impregnated with each concentration were placed on the media, followed by incubation at 37°C for 24 hours. The inhibition zones were measured to assess antibacterial activity. Results demonstrated a concentration-dependent increase in antibacterial efficacy, with inhibition zone diameters ranging from 8.3 mm at 20% extract to 20.3 mm at 100% extract concentration. The highest concentration’s inhibition zone was comparable to that of Cefadroxil (22.5 mm). No inhibition was observed in the negative control. Statistical analysis confirmed significant differences between treatment groups (p < 0.05). The antibacterial activity of lime mistletoe extract is likely due to its bioactive phytochemicals such as flavonoids and phenolics, which are known to disrupt bacterial cell membranes and inhibit microbial growth. These findings suggest that Dendrophthoe petandra extract holds potential as a natural antibacterial agent, providing an alternative to conventional antibiotics amid growing resistance issues. Further studies involving isolation of active compounds, toxicity evaluation, and in vivo testing are recommended to validate its clinical applicability
Investigating Genetic Vulnerability to Environmental Exposures and Associated Lung Diseases: A Bioinformatics Study
Get PDFLung diseases induced by environmental exposures such as air pollution, cigarette smoke, and industrial particles remain a significant global health concern, contributing to high morbidity and mortality rates. Genetic variations are known to influence individual responses to environmental exposures, but the molecular mechanisms underlying these interactions are not well understood. This study aims to identify genetic variants, specifically Single Nucleotide Polymorphisms (SNPs), that may increase the risk of lung diseases using a bioinformatics approach. The analysis was conducted by integrating various public genetic databases, including PheWAS, GWAS Catalog, HaploReg v4.2, GTEx Portal, and Ensembl Genome Browser. SNPs were filtered based on p-value 1. Missense mutations in selected SNPs were further analyzed for gene expression in lung tissue and distribution across populations. From an initial 151 SNPs, 86 met the statistical criteria, and six were identified as missense variants. Two genes, TNIP1 and PSMB8, showed significantly high expression in lung tissue. SNP rs2071543 in PSMB8 exhibited a strong correlation with increased gene expression and demonstrated notable allele frequency variation across populations. These findings suggest that genetic variations, particularly in PSMB8, may contribute to individual susceptibility to lung diseases induced by environmental exposures. This study highlights the importance of multidatabase analysis in identifying genetic biomarkers and provides a foundation for the development of precision therapies for multifactorial lung diseases

Get PDFEnbal is a traditional food from Maluku, originally from the Kei Islands, made from bitter cassava (Manihot esculenta). This processed food product holds significant historical and cultural value. However, enbal can become a source of illness if not prepared properly, leading to contamination and an increased risk of foodborne diseases. This study aimed to determine the microbiological quality through total plate count (TPC) analysis and bacterial identification of enbal at several traditional markets in Ambon City. It was a descriptive observational study with a true experimental laboratory approach. The TPC results for enbal food samples from Mardika market ranged from 14.5 × 102 CFU/g to 4.85 × 104 CFU/g, Waiheru market ranged from 8.3 × 102 CFU/g to 3.2 × 105 CFU/g, Batu Merah market ranged from 11.0 × 104 to 3.0 × 105 CFU/g, and Passo market ranged from 2.4 × 102 CFU/g to 3.75 × 105 CFU/g. The results of bacterial species identification from the four enbal food samples revealed Klebsiella pneumoniae and Staphylococcus haemolyticus. Thus, it can be concluded that the four enbal samples examined are safe for consumption as they do not exceed the Indonesian National Standard (SNI) 01-2997-1996, which is 1 x 106 CFU/g

Antibacterial And Synergistic Potential of Hibiscus sabdariffa and Zingiber officinale Against Multidrug-Resistant Bacteria
Get PDFAntimicrobial resistance (AMR) is a global health challenge, particularly in developing regions where access to effective drugs is constrained. Medicinal plants provide an alternative due to their affordability, availability, and wealth of bioactive compounds. This study investigated the antibacterial properties of Zingiber officinale (ginger) and Hibiscus sabdariffa (roselle), both widely used in African traditional medicine, against selected bacterial pathogens. Methanolic extracts were prepared from dried rhizomes of ginger and calyces of roselle, and concentrations of 100%, 95%, 90%, and 85% were tested. Antibacterial activity was determined against Staphylococcus aureus, Escherichia coli, and Pseudomonas sp. using agar well diffusion. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) were established by serial dilution and subculture techniques. Statistical significance was assessed using one-way ANOVA and Duncan’s multiple range test at p < 0.05. Phytochemical analysis revealed steroids, terpenoids, and flavonoids in both plants. Ginger additionally contained saponins, alkaloids, tannins, and carbohydrates, whereas roselle uniquely presented cardiac glycosides. Antibacterial activity increased with concentration, with the 100% extracts showing the highest inhibition zones. The combined extract consistently produced larger inhibition zones compared to the individual extracts (p < 0.05). Ginger exhibited the strongest individual activity against S. aureus, while the combined extract was most effective against E. coli. Pseudomonas sp. was the least susceptible. MIC values confirmed these observations: S. aureus was the most sensitive (25 mg/mL), while E. coli and Pseudomonas sp. each recorded 50 mg/mL. MBC values were uniformly 50 mg/mL across all test organisms. The results demonstrate that ginger and roselle possess significant antibacterial properties, with ginger showing superior individual efficacy and roselle providing complementary metabolites that enhanced combination effects. Their synergistic action supports traditional polyherbal therapy and indicates potential as cost-effective, plant-based interventions against AMR. The findings underscore the need for further research to develop standardized formulations for therapeutic application
