Taking into account that the existing hypoglycemic medication does not provide the infringed metabolism with the complete compensation and does not impede the development of the serious complications at the diabetes, we have planned to study the intrafractional changes happened in phospholipids individual fractions in cerebral, hepatic and cardiac tissues of alloxanic and diabetic white rats after 4 and 7 multiple injections of the extract got from mollusk alloumenous gland. The investigations showed that almost in all tissues all phospholipids fractions have been restored to the level, the glucose becomes to the norm. It says that the extract got from the mollusk alloumenous gland has medical effect at the diabetes.
