Results from this study4

No result from this study comes from a test of the peptide.

Natural levels measured4

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

  1. 01HumanEndogenous levelObservational studyOther

    In gastric cancer patients, the body's own plasma thymosin alpha1 level was higher in patients with lymph node involvement than in those with negative nodes.

    In plain wordsIn gastric cancer patients, natural thymosin alpha1 levels in blood were higher with lymph node involvement than without.

    Summary · context
    Plasma thymosin alpha1 was measured in 52 gastric cancer patients using a newly developed radioimmunoassay. Twenty-one tumors and lymph nodes were examined for thymosin alpha1 using immunohistochemistry.

    This result measures the body's own Thymosin alpha-1. Nobody was given the peptide. It is not evidence about taking it.

  2. 02HumanEndogenous levelObservational studyOther

    In gastric cancer tissue, immunohistochemistry showed the body's own thymosin alpha1 in 52% of cancers.

    In plain wordsIn gastric cancer samples, natural thymosin alpha1 was found in about half of the tumors.
