چکیده انگلیسی:
The present study aimed to examine the effectiveness of silymarin compared to hydrocortisone on clinical and hematological alterations and organ injury (liver and heart) in a low-dose canine lipopolysaccharide (LPS)-induced sepsis model. Fifteen clinically healthy dogs were randomly categorized into three equal groups: Two dogs in group A, LPS (0.10 μg kg-1, IV) was injected (control, n = 5); Group B was similar to group A, with the difference that silymarin bolus (10.00 mg kg-1, IV, once) was injected 40 min after LPS injection. Group C was similar to group B with the difference that hydrocortisone bolus (2.00 mg kg-1, IV, once) was administrated instead of silymarin. Five mL of blood was collected at baseline, 1, 3, and 6 hr of the study. Septic control dogs experienced a significant reduction in red blood cells count (RBC), hemoglobin (Hb), and hematocrit (HCT) and a significant elevation in serum activities of aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), creatine kinase isoenzyme MB (CK-MB), and plasma cardiac troponin I (cTnI) concentration. We noticed a significant increase in RBCs, Hb, and HCT, and a significant decrease in AST, ALP, LDH, CK-MB, and cTnI in the silymarin group in comparison with hydrocortisone and control group. Our results suggested that silymarin had a positive influence on sepsis due to protecting RBCs, and decreasing organ (heart and liver) injury. These findings supported the hypothesis that silymarin could be more effective than routine corticosteroid therapy in sepsis.
