The effects of Epimedium koreanum Nakai on liver function in rats with kidney yang deficiency and kidney yin deficiency pattern models based on the " You Gu Wu Yun" theory
kidney yin deficiency (KYINDS) rats based on the theory of " You Gu Wu Yun." The study also investigated the connection between EK-induced liver injury and symptoms.
Methods
2
Seventy-two male SD rats were divided into normal
KYANGDS
and KYINDS groups using the random number table method. The KYANGDS model was established through intramuscular injection of 20 mg/kg of hydrocortisone
whereas the KYINDS model was established through daily gavage of 160 mg/kg of thyroid tablet suspension for 14 consecutive days. After successful modeling
the rats were divided into the normal
EK low-dose
EK high-dose
KYANGDS
KYANGDS + EK low-dose
KYANGDS + EK high-dose
KYINDS
KYINDS + EK low-dose
and KYINDS + EK high-dose groups using the random number table method. Animals in the drug groups were administered low (0.26 g/kg) and high (0.77 g/kg) EK extract doses through continuous gavage. The other groups received drinking water once a day for 28 consecutive days. Changes in body mass were monitored during the administration period
and serum alkaline phosphatase (ALP)
alanine transaminase(ALT)
aspartate transaminase(AST)
direct bilirubin
indirect bilirubin (IBil)
and total bilirubin (TBil) were measured at the end of administration using biochemical analyzers. The liver weight
visceral body ratio
and visceral brain ratio were measured. Hematoxylin and eosin staining were performed to observe the pathological changes in the liver.
Results
2
Compared with the normal group
the EK high-dose group showed a decrease in body weight on the 21st day during the drug administration period and an increase in IBil (
P
<
0.05); the KYANGDS group had lower body weight at each measurement time point from the third to the 28th day
higher ALP
and lower liver weight (
P
<
0.05). Compared with the KYANGDS group
the KYANGDS + EK high-dose group had decreased ALP levels (
P
<
0.05). The pathological damage of liver tissue
in each KYANGDS administration group improved
the presence of fat vacuoles were reduced
and pathological scores show a decreasing trend. Compared with the KYINDS group
KYINDS+ EK high-dose group exhibited a higher IBil level and a lower visceral brain ratio(
P
<
0.05).
Conclusion
2
EK has a small effect on the liver function of rats with KYANGDS within the dose range; however
it has a specific hepatogenic impact on normal and KYINDS rats
and EK-induced liver injury and the symptoms may be associated with each other.
