Comparison of protective effects of N-acetyl-cysteine and Hexamethylenetetramine on sulfur mustard induced pathological effects in human skin fibroblast cell line HF2FF using electron microscope

Aims: In this study the protective effect of hexamethylenetetramine (HMT) and N-acetyl-cysteine (NAC) were compared against sulfur mustard (HD) on human skin fibroblast cells line HF2FF.Materials & Methods: The effects of HD (180 |jM) and simultaneous or pre treatment with HMT (15 |jM) and NAC (0.1 mM) on cell death and cell organelles were investigated using electronic microscope. Results: The HMT and NAC prevented cell death more than 50% and about 35%, respectively. EM observation revealed that HD caused destruction of cell membrane and organelles (mitochondria, lysosome, etc.) and cell necrosis signs. HMT caused an increase in normal cells with intact lysosomes, but the reticulum endoplasmic and Golgi bodies were partially vacuolated and the Struma of some mitochondria was lost. In NAC group mitochondria were concentrated. Cytoplasm was not normal and nuclear had some signs of vacuolization, but destruction was less than control and cell organelles such as Golgi bodies and lysosomes remained intact. Conclusion: HD induces the destructive effects immediately after exposure and pretreatment is the most effective way. Application of either HMT or NAC strongly prevents the cell death and the organelles changes. The protective effect of HMT against the cell death is higher than NACʹs.
