目的
2
观察狼毒抑菌膏对2
4-二硝基氯苯(DNCB)诱导小鼠湿疹的影响。
方法
2
采用ICR小鼠40只,随机分为4组,每组10只,分别为正常组,模型组,尤卓尔组(0.09 g·kg
-1
),狼毒抑菌膏组(0.09 g·kg
-1
),除正常组外,其他各组小鼠耳廓及背部涂抹DNCB诱导建立慢性湿疹模型,24 h后经耳廓及背部给予相应药物,每日2次,连续10 d。实验结束后检测小鼠耳肿胀厚度与质量,进行耳变应评分,计算小鼠的脾脏指数,观察小鼠耳组织病理学变化,采用多因子检测技术测定白细胞介素-1
β
(IL-1
β
),人肿瘤坏死因子-
α
(TNF-
α
),白细胞介素-2(IL-2),白细胞介素-4(IL-4)等血清炎症因子的变化。
结果
2
与正常组比较,模型组小鼠右耳厚度及重量、耳肿胀度、耳廓变应评分、脾脏指数和血清中IL-2与IL-4水平明显升高(
P
<
0.05,
P
<
0.01),并出现明显的湿疹样病理改变。与模型组比较,狼毒抑菌膏可有效减轻模型组小鼠的耳廓肿胀程度、降低模型组耳廓变应评分和脾脏指数、同时明显降低血清IL-2与IL-4水平(
P
<
0.05,
P
<
0.01),改善耳部组织病理形态。
结论
2
狼毒抑菌膏通过一定程度的抗炎作用达到慢性湿疹的治疗效果。
Objective
2
To observe the anti-inflammatory effect and its mechanism of Euphorbiae Ebarcteolatae Radix bacteriostasis ointment in eczema mice induced by 2
4-dinitrochlorobenzene (DNCB).
Method
2
A total of 40 ICR adult mice were randomly divided into control group,model group,hydrocortisone Butyrate cream group (0.09g·kg
-1
) and Euphorbiae Ebarcteolatae Radix bacteriostasis ointment group (0.09 g·kg
-1
)
with 10 mice in each group. Except for the normal group
other groups were given DNCB to induce the chronic eczema model. Twenty-four hours after DNCB stimulation
they were given the corresponding drugs through auricle and back
twice a day for 10 days. After drug intervention
efforts were made to measure the change of thickness and weight of the middle ear
assess the allergic effect
and calculate the spleen index of the mice. Optical microscope was used to observe the pathological changes in ear tissues of mice. And the levels of serum interleukin-1
β
(IL-1
β
)
tumor necrosis factor-
α
(TNF-
α
)
interleukin-2 (IL-2)
interleukin-4 (IL-4) in mice were determined by multiplex immunoassay.
Result
2
Compared with control group
the thickness and weight of right ears
score of allergic effect
spleen index and the levels of IL-2 and IL-4 in serum showed significant increases in model group (
P
<
0.05,
P
<
0.01). The histopathology injuries of ear were aggravated. Compared with model control group
Euphorbiae Ebarcteolatae Radix bacteriostasis ointment could reduce ear thickness and score of allergic effect
regulate the spleen index
decrease the inflammation factor in serum such as IL-2 and IL-4 (
P
<
0.05,
P
<
0.01)
and improve ear histopathology injuries.
Conclusion
2
Euphorbiae Ebarcteolatae Radix bacteriostasis ointment may have a good effect on eczema.
