[Changes in tissue basophils of skin and lymphoid organs in total, deep hypothermia].

The experiments have been performed on 60 white female rats with body mass 180-200 g. Under ether anesthesia the animals are cooled up to +18 degrees C of the rectal temperature, and then warmed up to +37 degrees C. Using certain morphometrical methods at staining paraffin slices with toluidine++ blue, tissue basophils (TB) in the dermis++, hypoderma, lymph nodes, thymus and spleen are studied. In response to cooling degranulation increases, some part of TB in all the organs is destroyed, this results in decreasing amount of the cells (except the thymus, where TB amount increases). The greatest pronounced decrease of TB amount occurs in the lymph node. The restorative reaction during the post-hypothermic period depends on the initial lesion. There are no TB in the spleen. In different organs TB demonstrate various sensitivity to hypothermia, that is evidently connected with their microenvironment and initial state at the moment of the experiment, as well as with various role of the organs investigated in the defensive-adaptive reactions of the organism.
