Background:Hepatocellular carcinoma is one of the most common cancers and a lethal disease. In view of the limited treatment and a grave prognosis of liver cancer, preventive control has been emphasized.Materials and Methods:The methanolic extract of roots of Cynodon dactylon was screened for its hepato-protective activity in diethyl nitrosamine (DEN) induced liver cancer in Swiss albino mice. The plant extract at a dose of 50 mg/kg was administered orally once a week, up to 30 days after DEN administration. The animals were sacrificed; blood sample and liver tissue were collected and used for enzyme assay such as, asparatate amino transferase (AST), alanine aminotransferase (ALT), catalase (CAT), glutathione peroxidase (GPx) and glutathione-S-transferase (GST). The liver marker enzymes AST and ALT produced significant results in the protective action.Results:The antioxidant enzyme assay results concerning the improved activity of GPx, GST and CAT. These results concluded that enhanced levels of antioxidant enzyme and reduced amount of serum amino transaminase, which are suggested to be the major mechanisms of C. dactylon root extract in protecting the mice from hepatocarcinoma induced by DEN. These biochemical observations were supplemented by histopathological examination of liver sections.Conclusion:The methanolic extract of C. dactylon possesses significant anticancer properties
A B S T R A C T BACKGROUNDGenitourinary tract infections are some of the most common infections in females. These problems are a challenge in terms of diagnosis and treatment. The present study was conducted to evaluate the prescribing pattern in three of the most common types of female genitourinary tract infections.
METHODSA prospective and observational study was conducted on genitourinary tract infections in female patients at the gynaecology outpatient department in a tertiary care university hospital.
RESULTSMajority of the infected female patients were in 26 -35 years age group (31.8%) followed by 36 -45 years age group (25.9%). The common infection noticed was urinary tract infection (42.2%), followed by pelvic inflammatory disease (32.2%) and vaginitis (25.5%) in infected female patients. The types of antibiotics prescribed for urinary tract infection were aminoglycosides, fluoroquinolones, cephalosporins and penicillins. The commonly prescribed antibiotics for pelvic inflammatory disease were tetracyclines, azoles, fluoroquinolones and cephalosporins, and for vaginitis azoles and aminoglycosides. The most commonly prescribed class of antibiotics for urinary tract infection, pelvic inflammatory disease and vaginitis were fluoroquinolones (11.8%), azoles (11.8%) and aminoglycosides (15.7%), respectively. Oral route was the preferred mode of administration (71%), followed by rectal (suppositories, 17.2%) and topical (cream, 11.8%).
CONCLUSIONSYoung married women in this urban Indian community have a high prevalence of genitourinary tract infections but seldom seek treatment. Education and outreach are needed to reduce the stigma, embarrassment and lack of knowledge related to genitourinary tract infections.
The development of formulations with therapeutic peptides has been restricted to poor cell penetration and in this attempt; we developed pACC1 peptide loaded chitosan nanoparticles. The prepared nanoparticles were characterized with FT-IR, XRD, SEM and TEM. In addition, the suitable formulation was evaluated for hemocompatibility, plasma stability and embryo toxicity using Danio rerio embryo model. The results showed that pACC1 peptide loaded chitosan nanoparticles were compatible with plasma. They possess sustained release pattern and also found to be safe up to 300 mg/L in embryo toxicity tests. Cytotoxicity assays with MDA-MB-231 cell lines suggested that, pACC1 peptide loaded chitosan nanoparticles were capable of enhanced cellular penetration and reduced palmitic acid content, which was confirmed by H 1 NMR . Hence, these nanoparticles could be employed as excellent adjuvant therapeutics while treating solid tumors with multi-drug resistance.
BACKGROUND Urinary tract infections are often caused by bacteria resistant to antibiotics which have evolved to be a major health issue in recent years. Often, urinary tract infections are very hard to treat and if not appropriately treated in time, may result in serious consequences, particularly, when it spreads to kidneys ultimately resulting in an increase in morbidity and mortality. Nitrofurantoin, a first line agent and has bactericidal action, frequently used to treat uncomplicated urinary tract infection. The literature was searched with published sources from Medline, PubMed and Embase search engines. Published articles were searched, of which 81 articles were eligible to be included for this systematic review. Nitrofurantoin is reduced by the action of bacterial flavoproteins to reactive intermediate compounds that non-specifically inactivate ribosomal proteins resulting in inhibition of protein synthesis. Various mechanisms seem to be responsible for the reduced capability of microorganism to acquire resistance in a faster manner. Nitrofurantoin exhibits high quality success against most bacteria anticipated in urinary tract infection. Nitrofurantoin has been recommended for prophylaxis in the treatment of reinfection in case of recurrent uncomplicated urinary tract infections in many western countries. Nitrofurantoin is one of the treatment options for urinary tract infection due to extended spectrum beta lactamase producing Escherichia coli. In pregnant women with urinary tract infection, nitrofurantoin can be appropriate treatment. Also, nitrofurantoin associated reactions have been reported in many studies. This review updates the clinical use of nitrofurantoin, including new facts about the role of nitrofurantoin in the therapy of community acquired urinary tract infection, adverse outcomes, complications, interactions and antibiotic resistance mechanism against different uropathogens.
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.
