background: helicobacter pylori (hp) infection is one of the commonest contaminations in the worldwide, and particularly in developing counties. it has found in a few of pulmonary disorders. however, the status of hp infection has not been known among the population of sulfur mustard(sm) induced respiratory diseases. the purpose of the study was to detect hp infection among asymptomatic sm focu...

background: about 100,000 iranian have been exposed to chemical weapons during iraq‑iran conflict (1980‑88). after being spent of more than two decades, still about 30,000 of them are under follow‑up treatment. the main aim of this study was to review various preventive and therapeutic methods for injured patients with sulfur mustard in different phases. methods: for gathering information, we h...

Half mustard (CEES) and nitrogen mustard (NM) are commonly used surrogates and vesicant analogs of the chemical warfare agent sulfur mustard. In the current study, in situ forming poly(ethylene glycol) (PEG)-based doxycycline hydrogels are developed and evaluated for their wound healing efficacy in CEES and NM-exposed rabbit corneas in organ culture. The hydrogels, characterized by UV-Vis spect...

Sulfur mustard (SM) is a potent vesicant that has been employed as a chemical weapon in various conflicts during the 20th century. More recently, mustard was used in the Iraq conflict against Iranian troops and civilians. At the present time there are more than 40.000 people suffering from pulmonary lesions special bronchiolitis obliterans (BOs) due to mustard gas. SM increases the endogenous p...

Bis(2-hydroxyethylthio)alkanes and bis(2-hydroxyethylthioalkyl)ethers are important biological and environmental degradation products of sulfur mustard analogs known as sesqui- and oxy-mustards. We used atmospheric pressure chemical ionization mass spectrometry (APCI MS) to acquire characteristic spectra of these compounds in positive and negative ionization modes. Positive APCI mass spectra ex...
