Magnesium is an essential metal that has important roles in physiological function of the body organs. Ethambutol is an oral antitubercular agent with chelating effects owing to its chemical structure. The aim of present study is to determine whether ethambutol usage can alter serum magnesium concentration in patients with pulmonary tuberculosis. Sixty patients with diagnosis of pulmonary tuber...

In Figure 1 the unit of measure stated in the Y axis for urinary 3-NT to creatinine ratio should be nM/mg10-1 (nanomoles) and not microM/mg 10-1 as reported and for urinary 3-NT should be nM/L (nanomoles/L) and not microM/L as reported. The authors would like to apologize for this error.

INTRODUCTION: This study aimed to evaluate a new commercial kit, Kit SIRE Nitratase-PlastLabor, for testing the drug susceptibility of clinical Mycobacterium tuberculosis isolates. METHODS: The accuracy of the Kit SIRE Nitratase was evaluated by examining the susceptibility (streptomycin, isoniazid, rifampicin, and ethambutol) of 40 M. tuberculosis isolates, using the proportion method with L...

TO THE EDITOR—We read the metaanalysis by Bastos et al recently published in Clinical Infectious Diseases [1]. Because of our interest in the association of drug susceptibility testing (DST) results for firstand second-line drugs with treatment outcomes in patients with multidrugresistant (MDR) tuberculosis and extensively drug-resistant (XDR) tuberculosis, we carefully read the entire article....

A simple column chromatographic method for determination of ethambutol (EMB) in pharmaceutical preparations containing EMB in combination with other anti-TB drugs is presented. The method involved extraction of EMB into an organic solvent, followed by basification and column chromatographic separation on Amberlite CG 50 (100-200 mesh) and elution with suitable eluants and estimation at a wavele...

Objective: In the study, 419 Mycobacterium tuberculosis complex strains (MTC), which were isolated from samples sent to Regional Tuberculosis Laboratory in our city between 2015 and 2019 with suspected Erzurum surrounding cities investigated. Methods: Our research is a retrospective cross-sectional study clinical Public Health suspicion of within five-year period January December first evaluate...
