Abstract: | A comparative study of phospholipid composition of thymus, spleen, bone marrow, liver and peritoneal exudate with sarcoma 45-bearing and normal rats was carried out. It was found that substantial changes in total phospholipid and cholesterol contents are observed only in peritoneal exudate of tumour-bearing animals. Some alterations were revealed in the content of individual fractions of investigated organs. The most pronounced changes in the contents of individual phospholipid fractions were found in peritoneal exudates of rats with sarcoma 45. |
