Article information
Abstract
Objectives:
Atopic dermatitis is a chronic inflammatory skin disease characterized by pruritic and erythematous skin lesions. The purpose of this study was to investigate the suppressive effects of Lonicerae Flos, Forsythiae Fluctus and Hwangryunhaedok Decoction Pharmacop-uncture on the development of atopic dermatitis-like skin lesions in NC/Nga Mice.
Methods:
The Atopic Dermatitis was induced by biostir AD on the mice’s back skin. Experimental groups were divided into three including LFP (Lonicerae Flos Pharmacopuncture, EtOH extract), FFP (Forsythiae Fluctus Pharmacopuncture, EtOH extract) and HHP (Hwangryunhaedok Decoction Pharmacopuncture, Hydrodistillation extract). Every second day, the mice of three groups were treated with 0.1 ㎖ of pharmacopuncture using a syringe at right and left acupoints (BL13), alternatively. On the control group, normal saline was used instead of pharmacopuncture. Subsequently optical observation with a handscope, a clinical skin score, Tissue(general/immune) mast cell, Serum IgE level, Serum histamine level, and Serum lymphokine(IL-2, IL-4, IFN-γγ) were measured.
Results:
FFP and HHP decreased the clinical skin score, the total cell number of mast cells, and the Serum total IgE level and Serum histamine level. In Serum lymphokine levels, all groups were decreased to the IL-4 level, LFP and FFP were increased to the IL-2 level, and LFP was increased to the IFN-γ level.
Conclusions:
From the above results, Forsythiae Fluctus Pharmacopuncture (EtOH extract) and Hwangryunhaedok Decoction Pharmacopuncture (Hydrodistillation extract) exerted anti-allergic and anti-inflammatory effects, suggesting a promising agent for improving atopic dermatitis related symptoms.

Handscopic observation of atopic dermatitis like skin lesions for 3 weeks
1a. Normal mice; 1b∼d, atopic dermatitis NC/Nga mice model induced by biostir AD for 3 weeks; scaling/dryness and edema(1b), scaling/dryness, and erythema/hemorrhage(1c), scaling/dryness, erythema/hemorrhage and excoriation/erosion(1d).

Effects of pharmacopuncture treatment for 2 weeks on handscopic observation of atopic dermatitis
2a. control group; 2b. LFP group; 2c. FFP group; 2d. HHP group.
Handscopic features of FFP(2c) group were observed lower clinical skin scores graded on the skin lesions(scaling/dryness) compared to LFP(2b) and HHP(2d) groups.

Effects of pharmacopuncture treatment for 3 weeks on handscopic observation of atopic dermatitis
3a. control group; 3b. LFP group; 3c. FFP group; 3d. HHP group.
Handscopic features of FFP(3c) group and HHP(3d) group were observed lower clinical skin scores graded on the skin lesions(scaling/dryness) compared to control group(3a).

Histological section of atopic dermatitis after pharmacopuncture treatment for 3 weeks (toluidin blue, × 200)
4a. control group; 4b. LFP group; 4c. FFP group; 4d. HHP group.
Distribution of mast cells in the skin of FFP(4c) and HHP (4d) groups were more decreased compare to that of control(4a) group. Degranulated mast cells were more increase in control group(4a) compare to the other groups(4b∼d).
