Study on TCM syndromes of doxorubicin-induced cardiotoxicity mice model
Aimed to establish a stable doxorubicin-induced cardiactoxicity (DIC) animal model by observing the macroscopic signs and microscopic indexes of DIC in mice
to establish a stable animal model of DIC combined with disease and syndrome
and to explore the regularity of traditional Chinese medicine(TCM) syndrome changes in DIC mice model.
Methods
2
SPF grade C57 BL/6 wild-type mice randomly devided into the normal group(
n
=10) and the model group(10=10)
the model group mice were injected with adriamycin 5 mg/kg by the tail vein injection
and the normal group were injected with normal saline
once a week for 4 weeks. Echocardiography and pathological staining of HE
Masson and TUNEL were used to evaluate the model. The general condition of mice was observed every week
and the RGB value ratio of tongue and exhaustive swimming time bearing weight were recorded. The serum levels of lactate dehydrogenase (LDH)
creatine kinase isoenzyme (CK-MB)
malondialdehyde (MDA)
superoxide dismutase (SOD)
nitric oxide (NO) and tissue adenosine triphosphate (ATP) were detected by biochemical method .
Results
2
Compared with the normal group
from the first week
the mice in the model group showed listlessness
increased activity wheezing
decreased activity
decreased body weight (
P
<
0.01)
and shortened exhaustive swimming time (
P
<
0.05). From the 2nd week
the r value of tongue was decreased (
P
<
0.01)
while the g value and b value were significantly increased (
P
<
0.01). In addition
compared with the normal group
the levels of LDH
CK-MB and MDA in the model group were increased (
P
<
0.01)
and the contents of SOD
NO and ATP were decreased (
P
<
0.01).
Conclusion
2
In the DIC mice model
macroscopic signs and syndromes change with time and disease progression. The result of microscopic blood biochemistry and macroscopic signs showed that the DIC mice model appeared qi deficiency syndrome at week 1
and gradually evolved into qi deficiency and blood stasis at week 2-4.
