Abstract

The objective of the present study was to evaluate the biochemical effect of probiotics treatment on Thioacetamide (TAA)
induced liver fibrosis in rats. Thirty white male Sprague Dewily rats of 8-10 weeks old and Weighing 150 to 200 g were
used in the experiment. Rats were randomly divided in to 2 main groups, 1st group acts as normal control, 2nd group was
injected with TAA intraperitoneally (200mg/kg b.wt) twice a week for 6 weeks for the induction of liver fibrosis, after
that the 2nd group was subdivided into 2 subgroups1st subgroup received no drugs and served as positive control, 2nd
subgroup was treated with a daily dose of probiotics (0.0128×109 bacteria per gram of rat body weight) which is
equivalent to (135mg/kgb.wt) orally for 6 weeks. Blood samples were collected twice after 3 and 6 weeks of probiotics
treatment for biochemical examination, then rats were decapitated and liver specimens were collected for
histopathological examination. Intraperitoneal supplementation of TAA caused increase in serum level of AST, ALT,
Tbil, Dbil and pro-inflammatory cytokines as TNFα and IL6, decrease in serum level of Albumin and total protein.
Furthermore, histopathological examination revealed extensive degeneration, inflammatory infiltration and nodulation of
the liver. Probiotics treatment revealed decrease in serum level of ALT, AST, Tbil, Dbil and pro-inflammatory cytokines
as TNFα and IL6, decrease in serum level of Albumin and Total protein. Moreover, histopathological examination
revealed mild inflammation and less nodulation of the hepatic parenchyma.
