Beneficial effects of allicin on lead induced tissue enzyme alterations in common carp (Cyprinus carpio)
سال
: 2011
چکیده: Introduction: In toxicological studies, the alterations in the
enzymatic activities directly reflect the metabolic disturbances and
cell damage in specific organs. The aim of the current study was to
determine the effects of lead exposure on tissue enzyme activities of
aspartate aminotransferase (AST), alanine aminotransferase (ALT),
alkaline phosphatase (ALP) and lactate dehydrogenase (LDH) in
selected tissues of common carp and also to evaluate the beneficial
effects of allicin, the main active constituent of garlic, on modulating
enzyme alterations.
Methods: Common carp (Cyprinus carpio; total, n=60) were
divided randomly into three groups of 20 each. Group I fish were
reared in normal freshwater and served as the control. Group II fish
were exposed to lead acetate (7.0 mg L−1) for 10 days. Group III fish
were exposed to lead acetate (7.0 mg L−1) for 10 days and also
received dietary allicin (10 mg/kg body weight, daily) during lead
acetate treatment. At the end of each exposure, enzyme activities in
prepared tissue homogenates were determined using colorimetric
methods.
Results: Lead exposure caused a significant elevation of AST, ALT
and LDH in the liver, as compared to control group (P<0.05). The
AST, ALT, ALP and LDH levels in kidney homogenates were
considerably increased following lead exposure, although these
increases were only significant for ALT and ALP values. Significant
increases of brain ALT and gill ALP activities were also observed
following lead exposure. However, alterations in the activities of
other measured enzymes in both brain and gill of experimental
groups were not significant.
Conclusion: Allicin supplementation was effective in attenuating
the increase in Pb-induced tissue enzyme activities in the most
organs; therefore it might have some protective and therapeutic
effects on lead poisoning. However, much more extensive biochemical
and toxicological research are needed for better understanding of
the molecular basis of lead induced tissue enzyme alterations and
ameliorative properties of allicin.
