[Morphological study of animal erythocytes using the scanning electron microscope]

Area of Science:

• Veterinary Medicine
• Hematology
• Cell Biology

Background:

• Erythrocyte morphology is crucial for oxygen transport and can be affected by various physiological states.
• Understanding species-specific erythrocyte characteristics is essential for accurate health assessments.
• Changes in erythrocyte morphology can indicate underlying pathological or stress-induced conditions.

Purpose of the Study:

• To investigate and document the erythrocyte morphology of eight different animal species.
• To analyze alterations in erythrocyte morphology associated with aging, pathological conditions, and stress.
• To observe the effects of blood storage on erythrocyte morphology.

Main Methods:

• Utilized an ISM-35 scanning electron microscope for high-resolution imaging of erythrocytes.
• Examined erythrocytes from eight animal species under direct fixation conditions.
• Monitored morphological changes in erythrocytes during 168 hours of storage in 'Olsever' conservant.
• Assessed erythrocyte morphology in animals subjected to immunization and stress states.

Main Results:

• Presented detailed morphologic profiles, including forms, sizes, and proportions, for erythrocytes of eight species.
• Documented significant erythrocyte morphological modifications occurring during blood storage.
• Observed distinct changes in erythrocyte morphology in immunized and stressed animals.

Conclusions:

• Scanning electron microscopy provides valuable insights into species-specific erythrocyte morphology.
• Erythrocyte morphology is sensitive to aging, disease, stress, and storage conditions.
• These findings contribute to a better understanding of erythrocyte behavior in various physiological and experimental contexts.
