Morphological characterization of lymphoid cells conjugates with scattered tumor target cells in organ imprints of Yoshida ascites bearing rats

The authors analysed morphologically the ability of host effector cells to bind disseminated tumor target cells (pre-lysis) in vivo. Scattered tumor cells are morphologically visible stained with May Grünwald-Giemsa in the lung, liver, kidney, and spleen imprints of Yoshida ascites tumor bearing rats. Lymphoid cells can be seen binding disseminated tumor target cells in organs but not in the peritoneal cavity. This model may provide a useful technique for morphological studies on the in vivo conjugation capacity of host effector cells against tumor target cells.     

Histoautoradiographic investigation of the invasive dissemination of Ehrlich ascites tumor cells through the organs of the mouse.

In this paper the attempt has been pursued to quantify by a well planned experimental technique the ability of the neoplastic cells to spread around in vivo through various organs of laboratory animals. By making use of the histoautoradiographic techniques the incorporation of 3H thymidine either by the normal and by the neoplastic cells has been investigated at many different anatomical sites in Ehrlich ascites tumor-bearing mice. The method has been shown to be well suited also for the quantitative characterization of the spreading dynamics of the cancer cell population.     

Single and combined effects of two trace elements (Cd and Cu) on the asexual reproduction of Aurelia sp. polyps

Aquatic Ecology - Jellyfish blooms are an increasingly common event in our seas. Occurring via polyps’ asexual reproduction induced by human stresses, they represent a hazard for ecosystems...
