Enhanced Anti-Inflammatory Activity of Passiflora edulis Leaf Extract Nanoparticle Gel in Carrageenan-Induced Rat Model
Full text linkPassion fruit (Passiflora edulis) leaf extract is rich in flavonoids, which possess anti-inflammatory properties. This study aimed to enhance the anti-inflammatory effect of the extract through a nanoparticle gel formulation. Nanoparticles of the extract (NEP) were prepared using ionic gelation with a Carbomer 940 base. The anti-inflammatory efficacy of NEP was evaluated in vivo using a carrageenan-induced paw edema model in rats. Five groups (n=5) were tested: a negative control (Carbomer 940 gel base), a positive control (Sodium Diclofenac), and three NEP formulations with concentrations of 1% (NEP-1), 3% (NEP-2), and 5% (NEP-3).
The NEP gels were homogeneous with a faint yellow color and a characteristic odor. Their spreadability ranged from 7.50 ± 0.67 cm to 7.69 ± 1.26 cm, viscosity exhibited plastic flow properties, and pH values were within 4.47 ± 0.06 to 5.20 ± 0.10. The anti-inflammatory effectiveness of NEP formulations increased with concentration, achieving edema inhibition rates of 3.66% (NEP-1), 68.47% (NEP-2), and 82.37% (NEP-3).
In conclusion, the nanoparticle gel formulations of passion fruit leaf extract demonstrated good physical properties, with NEP-3 being the most effective in reducing carrageenan-induced paw edema in rats
Antioxidant Properties, α-Amylase and α-Glucosidase Inhibitory Activities of Maesobotrya barteri Leaves Extracts in Rats
Full text linkMaesobotrya barteri is widely used in Nigerian ethnomedicine to treat diabetes, arthritis, and infections. In this study, the methanol and aqueous leaf extracts' phytochemical constituents and antioxidant potentials were evaluated using standard procedures. At the same time, the enzyme inhibitory activity of methanol extract on α-amylase and α-glucosidase in rats was also investigated. The antioxidant properties of the extracts were evaluated by the 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity and ferric reducing power (FRAP). Phytochemical screening of methanol and aqueous extracts revealed the presence of flavonoids, alkaloids, saponins, tannins, and cardiac glycosides. Total phenolics and flavonoids of the extracts ranged from 0.04 to 3.18 mg of GAE/g and from 27.70 to 57.70 mg of QE/g, respectively. Antioxidant analysis showed IC50 values of DPPH (192.95, 196.04, and 17.19 µg/mL) and FRAP (30.48, 37.64, and 38.15 µg/mL) for the methanolic extract, aqueous extract, and ascorbic acid, respectively. Assessment of the methanolic extract against α-amylase and α-glucosidase enzymes in rats at doses of 150, 300, and 450 mg/kg using starch, sucrose, and maltose as substrates, with acarbose as a reference drug, significantly reduced blood glucose levels (p < 0.05). These findings suggest that M. barteri leaf extract has antioxidant properties and inhibits both α-amylase and α-glucosidase enzymes in rats, likely due to the phytochemicals present in the extract
Differential Regulation of Slc40a1, Fth1, and Hmox1 by Deferasirox in Splenic Iron Overload
Full text linkIron overload, often arising from repeated transfusions in thalassemia major, disrupts iron homeostasis and induces oxidative stress. Deferasirox is a widely used oral chelator, yet its effects on splenic iron-regulatory gene expression remain unclear. This study investigated the impact of deferasirox on ferritin heavy chain (Fth1), ferroportin (Slc40a1), and heme oxygenase-1 (Hmox1) expression in a rat model of splenic iron overload. Eighteen male Wistar rats were randomly assigned into three groups (n = 6 each): normal (N), iron dextran-induced overload without treatment (KN), and iron overload treated with deferasirox (KP). Gene expression was quantified by real-time PCR using the 2−ΔΔCT (Livak) method, with statistical analysis performed via one-way ANOVA and Tukey’s post hoc test. Iron overload significantly upregulated Fth1 (2.26-fold) and Slc40a1 (1.72-fold) versus controls (p 0.05). In contrast, Hmox1 expression markedly increased (55.25-fold, p < 0.05) following deferasirox administration. These results indicate that deferasirox selectively modulates splenic iron-regulatory genes, suggesting both chelation and adaptive stress-response mechanisms, thereby supporting its therapeutic role in managing iron overload
Hair Growth and Antibacterial Effects of Nanoparticle-Based Cosmeceutical Tonic from Pogostemon cablin and Morus alba Leaves
Full text linkHair loss affects a substantial portion of the global population, regardless of age or gender. One effective strategy to address this problem is the use of hair tonics that stimulate hair follicle activity and promote hair growth. This study developed an innovative cosmeceutical nanoparticle-based hair tonic combining Nilam and Mulberry leaf extracts, termed nanoNilamBerry. The formulation was prepared using the ionic gelation method and evaluated on rabbits over 28 days by assessing hair length, growth rate, and hair weight. The nanoNilamBerry formulation fulfilled the physicochemical requirements of a nanoparticle system and demonstrated good stability at 4 °C, 25 °C, and 40 °C for up to 28 days. In antibacterial assays against Staphylococcus epidermidis, the Nilam–Mulberry extract produced an inhibition zone of 16.36 ± 0.35 mm, while nanoNilamBerry exhibited a larger zone of 18.4 ± 0.30 mm. The hair tonic formulation showed no signs of skin irritation. The nanoNilamBerry treatment resulted in a hair growth rate of 0.13 ± 0.03 cm/day and a final hair weight of 32.36 mg, compared to 0.09 ± 0.01 cm/day and 27.3 ± 0.31 mg for the simple Nilam–Mulberry extract. Overall, the nanoNilamBerry hair tonic demonstrated superior efficacy, promoting hair growth 3.04 times faster than the untreated control and 1.45 times faster than the non-nano extract combination. These findings indicate that nanoNilamBerry not only provides effective antibacterial protection but also significantly enhances hair follicle stimulation and growth performance
Ethyl Acetate Fraction of Gynura procumbens Mitigates Hyperglycemia, Dyslipidemia, and Tissue Damage in Streptozotocin-Induced Diabetic Rats
Full text linkDyslipidemia is a lipid metabolism disorder frequently associated with diabetes mellitus and known to increase cardiovascular risk. Although Gynura procumbens has been reported to possess antidiabetic and antidyslipidemic properties, studies focusing on the specific effects of its ethyl acetate fraction remain limited. This study investigated the therapeutic potential of the ethyl acetate fraction of ethanol extract from G. procumbens in streptozotocin-induced diabetic rats, particularly its impact on blood glucose, lipid profiles, and histological changes in pancreatic and aortic tissues. Thirty rats were randomly assigned to six groups: normal control, diabetic control, glibenclamide, simvastatin, and extract-treated groups at 100 and 150 mg/kg body weight. After 28 days of treatment, the 150 mg/kg dose significantly reduced blood glucose by 61.3%, total cholesterol by 42.1%, triglycerides by 47.3%, and LDL by 55.0%, while increasing HDL by 6.3% compared to diabetic control (p < 0.05). Histological analysis demonstrated regeneration of pancreatic β-cells and improvement of vascular structure in the aorta. These findings suggest that the ethyl acetate fraction of G. procumbens may serve as a promising natural agent for managing diabetes and dyslipidemia
Evaluation of Antibiotic Use in Inpatient and Outpatient Diabetic Ulcer Patients at a Government Hospital in Bandung
Full text linkDiabetic foot ulcers are caused by neuropathy and/or peripheral arterial disease in patients with type 2 diabetes mellitus. These infections are commonly treated with empirical antibiotics. However, excessive or inappropriate antibiotic use may lead to resistance and poor treatment outcomes. This study aimed to evaluate antibiotic prescribing patterns, rationality, and potential drug interactions in diabetic ulcer patients at a government hospital in Bandung from January to December 2023. A retrospective observational design was used to analyze medical records of 63 patients. The most frequently used single antibiotics were ceftriaxone (51%), cefixime (20%), and ceftizoxime (17%), while the most common combination therapy was ceftizoxime + metronidazole (24%). Evaluation of antibiotic rationality showed 100% appropriate indication, 90.48% appropriate drug selection, and 98.41% appropriate dosage. Despite this, 33.33% of prescriptions had potential drug interactions with commonly co-prescribed medications. These findings indicate generally rational antibiotic use with areas for improvement in drug selection and interaction management. The study highlights the importance of continuous monitoring and rational prescribing to prevent antimicrobial resistance and ensure patient safety
Evaluation of Medication Errors in Transcribing and Dispensing Processes of Outpatient E-Prescriptions at Persahabatan General Hospital
Full text linkPersahabatan General Hospital provides a variety of healthcare services, including outpatient care. Medication errors are errors in the prescribing, dispensing, and administration process that can be considered risk factors for patients. This study aims to evaluate medication errors in the transcription and dispensing phases of outpatient e-prescriptions at Persahabatan General Hospital during the period January - February 2024. This research is a descriptive observational study with a cross-sectional design. Data were collected through prospective observation and analyzed descriptively to determine the percentage of medication errors. Of the 363 e-prescriptions observed, the results showed no errors in the transcribing phase. However, in the dispensing phase, there were 50 (6.07%) incidents of incorrect preparing quantity of medicine, 8 (0.97%) incidents of incorrect medicine medical equipment, and 7 (0.85%) incidents of incorrect dosage. These findings suggest that although the implementation of e-prescribing is effective in reducing errors at the transcription phase, special attention must be paid to the dispensing phase to reduce the number of errors. There is a correlation between polypharmacy and medication errors in the dispensing phase, p-value <0.001. All of these errors are resolved before the medication is administered to the patient
Praecitrullus fistulosus Fruit Extract Ameliorates Type II Diabetic Complications in Rats: In Silico, In Vitro, and In Vivo Investigation
Full text linkThis study explored the safety and antidiabetic potential of a hydroalcoholic extract of Praecitrullus fistulosus fruits, along with qualitative and quantitative phytochemical analyses. The antidiabetic effect was evaluated using in vitro methods, including α-amylase and α-glucosidase inhibition assays, as well as an in vivo high-fat diet and low-dose streptozotocin-induced diabetic model. Molecular docking studies were conducted to identify phytochemicals responsible for the antidiabetic effects. The fruit extract exhibited maximum inhibition of 52.06% and 58.10% for α-amylase and α-glucosidase enzymes, respectively, at a concentration of 100 µg/mL. The extract also demonstrated a significant (p < 0.001) and dose-dependent antidiabetic effect at oral doses of 200 mg/kg and 400 mg/kg in the tested animals. In silico analysis revealed that α-tocopherol exhibited the best docking pose, with a docking energy of -8.2 kcal/mol. Based on the results, it can be concluded that the hydroalcoholic extract of Praecitrullus fistulosus contains phytochemicals effective in controlling glucose levels. This study also validates the traditional use of Praecitrullus fistulosus fruits in managing diabetes

Full text linkThis study aims to evaluate the effectiveness of a web-based drug information application in providing accessible and reliable drug-related information to the public in Gorontalo Province, Indonesia. A prospective, non-randomized study was conducted with 205 participants from the Gorontalo community. Participants completed a structured questionnaire assessing their experience with the "Cari Obatmu" feature on the Ikatan Apoteker Indonesia (IAI) Gorontalo website. The questionnaire covered various aspects such as user interface, search efficiency, clarity of drug indications, side effects, and usability. Descriptive statistics, Cronbach's Alpha for reliability, One-Way ANOVA for demographic differences, and effect size analysis were used in data analysis. The findings indicated high user satisfaction, with mean scores ranging from 4.16 to 4.28 across different aspects assessed. A Cronbach’s Alpha value of 0.975 confirmed excellent internal consistency of the data. The One-Way ANOVA analysis revealed no significant differences in satisfaction scores among demographic groups (p = 0.636), with effect sizes being minimal. The web-based drug information application was well-received, particularly for its functionality and ease of use. However, further improvements are necessary to enhance user experience and feature development. These findings highlight the potential to expand web-based drug information tools to improve public health outcomes in Indonesia, considering the diverse demographic and user needs
Effectiveness of TB-Reminder Application in Improving Medication Adherence and Quality of Life of Lung Tuberculosis Patients in Indonesia
Full text linkPoor adherence to anti-tuberculosis (TB) treatment continues to hinder therapeutic success and patient quality of life. This study aimed to evaluate the effectiveness of the TB-R mobile application in improving medication adherence and quality of life among pulmonary TB patients at Pandeglang Regional Hospital. Eighty-six patients were randomized into intervention (n = 43) and control (n = 43) groups. Adherence and quality of life were measured using the Medication Adherence Rating Scale (MARS) and EQ-5D-5L, respectively. After one month, the intervention group demonstrated significantly higher adherence (97.7% vs. 79.0%, p < 0.001) and improvement in mean MARS scores (24.7 vs. 22.7, p < 0.001). Although quality of life gains were not statistically significant overall, notable improvements were observed in anxiety/depression and self-care domains. Demographic factors influenced outcomes: patients aged 29–39 and those living with others showed better adherence, while patients aged 40–50 experienced greater quality of life gains. Women aged 51–60 living alone had decreased adherence despite quality of life improvements. These results suggest that mHealth tools like TB-R can enhance adherence, especially when supported by favorable social and demographic conditions. Tailored digital interventions may optimize treatment outcomes in TB care. Future mHealth app development should consider these social and demographic factors to maximize effectiveness and user engagement
