Abstract

 The present study was carried out to investigate studies of dried fennel and tiger nut in
normal and on carbon tetrachloride (CCl
4) induced DNA damage using one concentration
of each plants alone for 30 days in male albino rats.
A total of thirty male albino rats (150-200 g) were used in this study.Rats were divided
into 6 groups each of 5 animals. Group one was kept as a control –ve and fed on basal diet
only, while the two other groups were fed on basal diet mixed with grind dried fennel and
tiger nut at concentration (5 g / 100 g diet) for 30 successive days. Other three groups were
subcutaneous injected of CCl
4 (0.1 ml/100 g b.wt. for two weeks) to induced DNA damage
change .One of these group was left as a control +ve (subcutaneous injection of CCl
4),
where the other two groups were fed on basal diet mixed with grind dried fennel and tiger
nut at concentration (5 g / 100 g diet) for 30 successive days.
At the end of experimental period, blood samples were collected from each rat for
biochemical analysis and rats were then sacrificed to elucidate DNA damage in
hepatocytes.Subcutaneous injection of CCl
4 caused significant increase in serum levels of
AST,ALT,ALP,creatinine,urea, triglyceride,glucose,total cholesterol,LDL and lipid
peroxide (MDA) while the levels of serum total protein, albumin ,globulin , A : G ratio and
glutathione transferase (GST) were significantly decreased .The smear on agarose gel had
been observed in CCl
4 treated groups indicating random DNA fragmentation and a
hallmark of necrosis . Fennel and tiger nut significantly restored the serum levels of
biochemical parameters directed toward normal as compared with the control +ve group
(injected with CCl
4 ).
