Objective:
To observe the influence
of A-L Tonic Capsules on experimental hepatocarcinogenesis
and development induced by diethylnitrosamine (DENA)
in rates.
Methods:
The experimental rats were divided into
4 groups. Exception of Group D in which the rats were
only administered with DENA, the rats in A, B, C group
were administered with DENA and A-L Tonic Capsules (Group
A, the rates were previously fed with A-L Tonic for
8 weeks and then added DENA; Group B, DENA and A-L Tonic
were simultaneously administered; Group C, the rats
were administered by DENA for 7 weeks and then added
A-L Tonic) The liver of all rats was examined using
gross, light, and electron microscopic methods after
20 weeks administered with DENA.
Result:
All rats in Group D formed
hepatocellular carcinoma. There was difference in tumor
formation among A, B, C groups. Liver tissue toxic injury
induced by carcinogen in Group A was milder than those
in other experimental groups. A few rates in Group A
formed hepatocellular carcinoma and most of them only
showed cell proliferation nodules in liver due to the
stimulation of DENA while all rats in other experimental
groups formed hepatocellular carcinoma and even metastasis
happened.
Conclusion
A-L Tonic Capsules can effectively
prevent or postpone hepatocarcinogenesis in rats.
