Amino acids and their derivatives in tumour tissue from patients with breast cancer treated with Ukrain. Part VI.

The present study was undertaken to evaluate the influence of Ukrain on the amino acids pool and their derivatives in tumour tissue of ten patients with breast cancer, treated in the preoperative phase with Ukrain. The control group consisted of five patients of similar age and advancement of the disease, who did not receive Ukrain. The data obtained indicate that Ukrain influences cancerous tissue, as demonstrated at the level of amino acids. The most characteristic changes observed in cancerous tissue after treatment with Ukrain were increases in the levels of proline, taurine and glutamic acid.
