Pan masala extracts, with and without tobacco, showed genotoxic potential by increasing chromosome aberrations and other markers. These findings suggest pan masala contains direct-acting mutagens, even without metabolic activation.

Area of Science:

  • Genotoxicology
  • Environmental Health
  • Chemical Mutagenesis

Background:

  • Pan masala is a common oral தயாரிப்பு in South Asia, often containing tobacco.
  • Previous studies have raised concerns about the health risks associated with pan masala consumption.
  • Understanding the genotoxic potential of pan masala is crucial for public health.

Purpose of the Study:

  • To evaluate the genotoxic effects of dimethyl sulphoxide (DMSO) extracts of pan masala with (PM-T) and without (PM) tobacco.
  • To assess the role of metabolic activation in the genotoxicity of pan masala extracts.

Main Methods:

  • In vitro short-term assays were employed to assess genotoxicity.
  • Cytogenetic markers including chromosome aberration (CA), sister-chromatid exchange (SCE), and micronucleated cells (MNC) were analyzed.

Related Experiment Videos

  • Tests were conducted in the presence and absence of metabolic activation.

    • Main Results:

    • Pan masala extracts (PM-T and PM) significantly increased the frequency of CA, SCE, and MNC in cultures without metabolic activation.
    • Metabolic activation resulted in a weak genotoxic response, indicating direct-acting mutagenicity.
    • The solvent (DMSO)-soluble components of pan masala are implicated as direct-acting mutagens.

    Conclusions:

    • Pan masala, both with and without tobacco, exhibits significant genotoxic potential.
    • The genotoxicity appears to be mediated by direct-acting mutagens present in the extracts.
    • These findings highlight the potential health risks associated with pan masala consumption due to its mutagenic properties.
