Strobilanthes hamiltoniana (Paalkurinji), a perennial herb of the Acanthaceae family, has traditional use in treating ulcers, diabetes, arthritis, and wounds. S. hamiltoniana leaves were extracted using ethanol, chloroform, and water, and screened for phytochemicals using standard protocols. LC-MS analysis was used to identify flavonoids. Antioxidant activity was evaluated via DPPH, HRS, and FRAP assays, while anti-inflammatory activity was assessed using the NO scavenging assay. Additionally, DFT (B3LYP/6-311G(d,p)) calculations and molecular docking were performed to investigate interactions with antioxidant-related proteins: monoamine oxidase-B, catalase, cytochrome P450, and NFE2-related factor 2. Based on the DPPH assay, aqueous and chloroform extracts showed 25.74% and 45.94% inhibition, while ethanol and methanol extracts exhibited higher inhibition at 89.10% and 86%. HRS ranged from 25.5% to 86.4%, with ethanol extract showing the highest activity (86.4%) at 300 μg/ml and an IC₅₀ of 25.54 μg/ml. All extracts were effective in the FRAP assay, with ethanol showing the highest activity (79.41%, IC₅₀ = 28.24 μg/ml). In the NO scavenging assay, ethanol again showed the strongest activity (80.41%, IC₅₀ = 26.26 μg/ml). Molecular docking revealed catechin had...

Introduction: Schizophrenia is a multi-factorial neuropsychiatric disorder, influenced by environmental and genetic factors. The catechol-O-methyltransferase (COMT) gene is a crucial for the metabolism of dopamine. It has been thoroughly investigated for its potential role in SCZ. At the same time; several variants in the COMT gene have been reported in diverse populations in South Karnataka but remain unexplored. Aim: To assess the novel variants related to the COMT gene and their correlation with SCZ symptoms and other health issues in patients. Materials and Methods: The study was carried out on 80 patients aged between 18 and 60 years; the results were compared with healthy controls of 80. The samples of blood were collected for the DNA extraction. PCR was used to amplify the COMT gene, followed by sequencing to identify variants. Standardized scales were used for gauging the severity of the symptoms. Results: Two novel changes in a single nucleotide (SNPs) (non-synonymous) were identified in the COMT gene in exon -4 of two female SCZ patients out of 80...

Background: Drug Utilization Study offers useful methods for teaching and training in drug therapy. In our setting, there is no such study that describes the use of drugs post-operatively. As a result, this study was conducted to investigate the post-operative drug utilization pattern in indoor post-operative patients. Aim: To study the prescribing trends of drugs used in indoor adult post operative patients in general surgery unit. Methods: Prospective observational study was conducted in post operative patients in General Surgery wards and ICU for 12 months at a tertiary care teaching hospital. Results: Total 600 cases were studied. Majority of the patients managed were males (64.5%). Most of the patients were in 18-40 years age group (49.66%) and from rural background 69.33% (416). The most common surgical procedure performed was Appendicectomy (29%). A total of 4437 drug products were prescribed. Average number of drugs prescribed per encounter were 7.39±2.56. Only 41.08 % of the drugs were prescribed by Generic name. Antibiotics were prescribed to 99.66% of the encounters. Antibiotics per...

Tuberculosis (TB) continues to rank among the world’s most serious health problems despite the remarkable biomedical achievements. The objective of the study is to describe and characterize the adverse drug reactions associated with Anti Tubercular Therapy (ATT) in a tertiary care hospital. This was a cross sectional study done in the Department of Thoracic medicine, Government Medical College Krishnagiri between May 2023 and July 2023(3 months). Around 240 patients taking anti-tubercular drugs were screened and 98 patients (40.8%) among them were found to have adverse reactions to the therapy. Incidence of ADR was highest (8.3%) among (21-30) and (51-60) age groups. Among the type of detected adverse drug reactions induced by anti-TB drugs, gastritis (8.3%) was the most common, followed by rash (5%), hepatitis (4.2%) with hard of hearing (0.8%) and vision abnormality (0.8%) being the least common. Causality assessment revealed around 64 ADRs (26.7%) had possible relation to the drug usage. severity assessment of ADRs induced by ATT revealed mild in 52 patients (21.7%), moderate in 44 patients...

The current research is to develop an easy and eco-friendly method for synthesizing Flower silver nanoparticles [FAgNPs] and Stem silver nanoparticles [SagNPs] using an aqueous extract of flower and stem Leonotis nepetifolia, (L.) R. Br. (family: Lamiaceae), and to evaluate their antibacterial properties. The obtained sample of synthesized FAgNPs and SAgNPs were characterized by UV–vis spectrophotometer, Zeta potential, X-ray Diffraction [XRD], Field Electron- scanning electron microscope [FE-SEM], and Fourier transform infrared spectroscopy [FT-IR] analysis. The formation of FAgNPs and SAgNPs was confirmed by the observation of band between 300 nm to 700 nm UV–vis spectrum. The crystalline structure of FAgNPs and SAgNPs with a face- centered cubic (FCC) was confirmed by XRD. The responsible phytochemicals for the reducing and capping agents of FAgNPs and SAgNPs were observed with FT-IR spectra analysis. The FE-SEM monograph revealed the spherical shape and size of FAgNPs and SAgNPs. Hence synthesized AgNPs were found to be in nano size and stable. Furthermore, the biosynthesized FAgNPs and SAgNPs indicated adequate antibacterial activity against clinical pathogen,...
