[Microangiographic signs of blood vessel rearrangement during tumor growth]

In the experiment performed in mice with a subcutaneously implanted sarcoma-37 on the chin, rearrangement of the blood vessels has been followed by means of micro-roentgenography. In the process of the implanted tumour growth, the blood vessels undergo a profound functional-anatomical rearrangement, which develops, beginning from the first hours, in two ways: at the expense of the peripheral vessels rearrangement in the recepient and at the expense of real tumorous vessels development ensuaring vascular trophic of the tumour.
