Hematological changes produced in mice by ochratoxin A and citrinin

Area of Science:

• Toxicology
• Hematology
• Immunology

Background:

• Mycotoxins, ochratoxin A and citrinin, are common contaminants with known toxic effects.
• Understanding their impact on hematological parameters is crucial for risk assessment.

Purpose of the Study:

• To evaluate the hematological and related organ effects of ochratoxin A and citrinin exposure in mice.
• To assess changes in erythrocyte sedimentation rate, hematocrit, red cell indices, platelet count, bone marrow cellularity, spleen parameters, and serum calcium.

Main Methods:

• Mice were administered weekly injections of ochratoxin A (5 mg/kg) and citrinin (20 mg/kg) for six weeks.
• Hematological indices, bone marrow cell counts, spleen weight and cellularity, and serum calcium were analyzed.

Main Results:

• Ochratoxin A and citrinin significantly decreased platelet count, hematocrit, spleen weight, splenic cell count, and serum calcium.
• Erythrocyte sedimentation rate, mean corpuscular values, and red cell indices were significantly increased.
• Bone marrow cellularity, including erythrocyte, leucocyte, and megakaryocyte precursors, showed significant decreases.

Conclusions:

• Ochratoxin A and citrinin induce significant hematotoxicity and affect bone marrow and spleen function in mice.
• These mycotoxins can lead to anemia, altered blood cell production, and reduced immune organ integrity.
