The study of the Baikal seal’s cardiovascular system in normal and pathological conditions

The study of the Baikal seal’s cardiovascular system in normal and pathological conditions

2019 – 2021

The Baikal seal is the only endemic mammal of the lake. However, the intensive impact of anthropogenic factors on Baikal negatively influences the welfare of the animal. The mortality of seals caused by asphyxiation and cardiac insufficiency has recently increased. Nevertheless, the factors that created the heart damage have not been identified. 

The Lake Baikal Foundation’s project will aim at researching the features of the Baikal endemic animal’s cardiovascular system, investigation of the changes in its anatomy and functioning due to anthropogenic influence.  

The research will be conducted as a part of «Baikal Initiative» grant competition for young scientists under the leadership of Anikienko Inna. 

Goal:

  •  Investigation of main features of the Baikal seal’s cardiovascular system in normal and pathological conditions. 

Target:

  • To provide grant assistance to ISAU named after Ezhevskyfor implementing the corresponding project. 
  • As a part of assistance to conduct the following works in 2019-2021:
  1. To study the structure and topography of the heart and the main vessels of the Baikal seal’s body;
  2. To investigate the micro- and ultrastructure of the Baikal seal’s heart and vascular wall of the main arteries in relation to its age
  3. To determine reference values of biochemical, hemorheological and hematological parameters of the Baikal seal’s blood system in normal and ultrasound methods;
  4. To research the Baikal seal’s vascular crease in vivo using ultrasound methods;
  5. To study structural features of membrane of red blood cells, explained by the Baikal seal’s lifestyle.
