2. General Information 3. Introduction Sulfur mustard is a chemical warfare that affect human health Chronic bronchitis, lung fibrosis, corneal ulcer disease Clinical manifestations in lung disorders due to sulfur mustard are different Mustard lung is not responsive to corticosteroids Proteomic can identify and quantify novel proteins in plasma 4. Introduction Biomarkers of the presence or severity of disease states Proteomics pattern in bronchoalveolar lavage (BAL) fluid of SM exposed patients Proteins whose expression is up or down regulated compared to healthy controls Looking new markers in the plasma, using ethanol and 2-dimensional gel Understand nature of long term effects of mustard gas 5.

6. Electrophoresis - 2D gel

  • Electrophoresis was defined as the movement of charged particles in an electric field.
  • Its a biochemical separation method analytical, useful for visualization and separation of protein preparations in small.
  • It has the advantage that helps the analyst to determine quickly how many proteins exist in a particular preparation or degree of purity of a specific protein preparation.

7. Electrophoresis - 2D gel

  • 2-dimensional gel possess properties such as:
  • Transparency
  • Elasticity
  • Porosity
  • Controllable
  • Compatibility with a variety of chemical compounds that makes an excellent support means for electrophoretic separations.

  • Electrophoresis allows the experimental determination of properties such as isoelectric point and molecular weight (MW) of a protein.

8. Sulfurd Mustard and Lung Diseases

  • Sulfur mustard (SM)
  • Chemical warfare agent.
  • Remains a threat to human health.
  • Some complications of mustard gas exposure are:
  • Chronic bronchitis
  • Interstitial lung diseases
  • Chronic obstructive lung disease
  • Lung fibrosis
  • Bronchiectasis
  • Bronchiolitis obliterans (BO).

SerumAmyloid A1is an acute-phase protein that is induced, like CRP, by inflammatory mediators, including IL-6, IL-1b, and TNF-a, that rises in acute exacerbation of COPD. Yes Arredouani et al. Theydescribed the role ofhaptoglobinaffecting the immune system, showing that haptoglobin directly affects T-cells and suppress T-helper-cells through down-regulation ofcytokine production. Yes Mehrani H. et at. In a study of BAL fluid proteomics patterns in SM exposed patients, thehaptoglobinisoforms were significantly elevated in moderate and severe lung disease patients compared to mild and healthy controls Yes Nishiokaet al. The serum concentration ofhaptoglobinwas decreased during acute exacerbation in asthmatic children. No 24. Conclusions 25. Conclussion 26. Conclussion 27. Anexos 28.
