Bottom Line: Female BALB/c mice were sensitized by an intraperitoneal injection of OVA and subsequently challenged with nebulized OVA.Our findings indicated that SSEW decreased the accumulation of inflammatory cells (particularly, eosinophil and neutrophil) and regulated the balance in the production of Th1/Th2 cytokines and chemokine in BALF.Collectively, these results suggest that, because of its anti-inflammatory and antiasthma properties, SSEW may be useful in reducing airway inflammation in the treatment of allergic asthma.

ABSTRACT

Background: Samsoeum has long been used in Korea and other Asian countries as a traditional medicine to treat various diseases. In the present study, we investigated the antiasthma effect of the herbal medicine Samsoeum water extract (SSEW) using an in vivo ovalbumin (OVA)-induced asthmatic model.

Methods: Female BALB/c mice were sensitized by an intraperitoneal injection of OVA and subsequently challenged with nebulized OVA. We investigated the number of inflammatory cells, the production of Th1/Th2 cytokines and chemokine in bronchoalveolar lavage fluid (BALF), histological changes in lung tissue, the infiltration of inflammatory cells and hyperplasia of goblet cells in lung tissue, the levels of immunoglobulin E (IgE) in BALF and plasma, and the expression of inducible nitric oxide synthase (iNOS) in lung tissue.

Results: Our findings indicated that SSEW decreased the accumulation of inflammatory cells (particularly, eosinophil and neutrophil) and regulated the balance in the production of Th1/Th2 cytokines and chemokine in BALF. Moreover, SSEW suppressed the level of IgE in BALF and plasma, and inhibited the infiltration of inflammatory cells, hyperplasia of goblet cells, and the expression of iNOS in lung tissue.

Conclusions: Collectively, these results suggest that, because of its anti-inflammatory and antiasthma properties, SSEW may be useful in reducing airway inflammation in the treatment of allergic asthma.

Effect of SSEW on iNOS expression in lung tissues of OVA-induced mice. Lung tissues were homogenized and iNOS protein expression was determined using western blot analysis. (A) Expression of iNOS in the lung tissue. (B) Relative ratio: The relative levels of iNOS expression (normalized to β-actin) were quantified. NC, normal control group (vehicle); OVA, OVA-induced group (control); Mon, montelukast (30 mg/kg) + OVA-induced group (positive control); SSEW-100, SSEW (100 mg/kg) + OVA-induced group; SSEW-200, SSEW (200 mg/kg) + OVA-induced group. The values represent the mean ± S.E.M (n = 3/group). Significant differences at ##P < 0.01 compared with the NC group. Significant differences at *P < 0.05 compared with the OVA-induced group.

Mentions: To assess the association between the expression of the iNOS protein and bronchial asthma, we evaluated iNOS expression by western blotting. iNOS was markedly upregulated in the OVA group compared with the NC group. SSEW treatment (100 and 200 mg/kg) suppressed the upregulation of iNOS in a dose-dependent manner (Figure 6).Figure 6
