    Summary
    In this study, we demonstrate that such injections of thymulin result in a significant elevation in the levels of TNF-alpha (P<0.01), NGF (P<0.01) and PGE(2) (P<0.01) in the liver of the treated rats, in addition to the increase in the levels of IL-1beta.

Studies that did not test the peptide alone5

In this study, Thymulin (serum thymic factor) was a lab tool or a carrier, part of a mix, or the subject of a lab method. These results are not evidence about taking Thymulin (serum thymic factor).

    Summary
    Pretreatment with specific antagonists to each of these factors (polyclonal anti-TNF-alpha, anti-NGF antiserum and IL-1 receptor antagonist) did not result in the abolition of the hyperalgesia as assessed by the paw pressure, hot plate, paw immersion and tail flick tests.

    In this study, Thymulin (serum thymic factor) was a lab tool or a carrier, part of a mix, or the subject of a lab method. This result is not evidence about taking Thymulin (serum thymic factor).
