Protective Effect of Yinhuangshen Essential Oil on Skin Damage in Mice with Solar Dermatitis
To study the effect of Yinhuangshen essential oil in mice of solar dermatitis model by ultraviolet (UVB).
Method:
2
Sixty SPF BALB/c female mice were randomly divided into blank group
model group
Minlixiao group
and large and small-dose Yinhuangshen essential oil groups. Except for blank group
model group was given 0.25 mL·cm
-2
normal saline on the back every day. The Minlixiao group was given Min Lixiao every day. Low-dose Yinhuangshen essential oil group was given 0.125 mL·cm
-2
and large-dose group was given 0.25 mL·cm
-2
once a day
and the corresponding drugs were given continuously for 8 days. Except for blank group
all of the other groups were irradiated for 1.5 hours at 15 cm away from 308 nm UVB lamp on the 6th day. One hour and 24 hours after irradiation
mice were given corresponding drug once
and skin was observed 48 hours later. Contents of nitric oxide (NO)
nitric oxide synthase (NOS) and tumor necrosis factor-alpha (TNF-
α
) in some local skin homogenates were measured. The histopathological changes were observed by htoxylin eosin(HE) staining.
Result:
2
Compared with blank group
skin of model group was reddish
swollen and ulcerated
epithelium and adnexal were absent
a large number of inflammatory cells and necrosis were adhered to the surface
the local histopathological changes significantly (
P
<
0.01)
and NO
NOS
TNF-
α
were significantly increased (
P
<
0.01). Compared with model group
contents of NO
NOS and TNF-
α
in the skin tissue of Minlixiao group and Yinhuangshen essential oil group were significantly decreased
and it could remarkable reduce the pathological changes in local tissue morphology (
P
<
0.01).
Conclusion:
2
Yinhuangshen essential oil has a good effect in preventing and treating solar dermatitis.
