The beneficial effects of resveratrol supplementation on parasitemia, oxidative stress and serum biochemical parameters in Trypanosoma brucei infected dogs

Abstract

This study investigated the effect of resveratrol supplementation on parasitemia, oxidative stress and serum biochemical changes in the Trypanosoma brucei infected dogs. The mean pre-patent period (MPP) of infection was 5.75±0.96 (5-7) days and 9.00 ± 0.82 (8-10) days between infected un-supplemented and supplemented respectively, which differed significantly (p<0.05). There was a significant increase (P<0.05) in the activities of malondialdehyde (MDA) post infection (pi) on the infected untreated group compared with the infected treated groups and the control. The mean serum alanine aminotransaminase (ALT) and aspartate aminotransferase (AST) were significantly (P>0.05) higher than the infected treated groups. The mean ALT of infected treated with both resveratrol and diminazene aceturate (DA) was significantly (P<0.05) lower than other infected treated groups. The mean creatinine and blood urea nitrogen (BUN) levels were significantly (P<0.05) higher in the infected untreated group. The creatinine level of the infected treated with both resveratrol and DA was significantly (P<0.05) lower than other infected treated groups, whereas the BUN did not differ significantly (P>0.05) within the infected treated groups when compared with the control. The mean albumin and total protein were significantly (P<0.05) higher in the infected untreated group, but the infected treated groups did not show any significant (P>0.05) difference. However, the total protein was significantly (P<0.05) higher in the infected treated with resveratrol than in other infected groups. It was concluded that pretreatment with resveratrol is beneficial in managing T. brucei infection, as it delays the onset of parasitemia and restores damages done to the liver and kidneys when combined with diminazene aceturate.
