ABSTRACT

Objective:

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:

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-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-2 (IL-2), interleukin-4 (IL-4) in mice were determined by multiplex immunoassay.

Result:

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:

Euphorbiae Ebarcteolatae Radix bacteriostasis ointment may have a good effect on eczema.
