title: [Thrombocyte ultrastructure and function in animals at high altitude].
abstract: Ultrastructural peculiarities of blood plates and state of the thrombocytic line of hemostasis have been studied in yaks (Bos grunniens), the Tibet subspecies, living in the Kirghiz mountains at the altitude more than 3.200 m. As a control 6 cows (Bos taurus), constantly living at the altitude of 760 m, have been taken. Stereological analysis of the volume of thrombocytic alpha-granules and of the volume of blood plates in the yaks has been performed. Ultrastructure of thrombocytes in the yaks possesses certain essential peculiarities (polymorphism of mitochondria, difference in the structure of alpha-granules). A conclusion is made on adaptive specificity of thrombocytes in animals living at high altitude.
