Effect of Thymalin on the Tumor and Thymus under Conditions of Activation Therapy In Vivo
Plain-language summary
Paraphrased from the published abstract below — not a verdict on whether anything works.
In this rat study (albino outbred male rats with transplanted sarcoma 45), the authors examined effects of Thymalin, administered at doses lower than therapeutic doses, on tumor growth and thymus structure as part of activation therapy. The abstract reports tumor growth arrest and regression were observed in more than half of the animals, and in other cases tumor growth was suppressed by 78%. Microstructural changes in the thymus were described, including a significant increase in lymphoproliferative activity and in the content of tissue basophils and plasmocytes in the thymus lobules. Tumor regression was accompanied by development of stable antistress adaptation reactions described as calm and elevated activation, which the authors attribute to use of lower Thymalin doses modulated during the treatment course according to activation therapy regimens.
Abstract
Pronounced antitumor effect of Thymalin in doses lower than the therapeutic doses was shown in experiments on albino outbred male rats with transplanted sarcoma 45. Tumor growth arrest and its regression were observed in more than half of animals and in other cases, the growth was suppressed by 78%. Microstructural changes in the thymus were analyzed. Significant increase in lymphoproliferative activity and the content of tissue basophils and plasmocytes in the thymus lobules was observed. Tumor regression was accompanied by the development of stable antistress adaptation reactions of calm and elevated activation. High efficiency of Thymalin can be attributed to the use of lower doses of the substance and their modulation during the treatment course in accordance with the regimes of activation therapy.
