Abstract:
As recorded, agarwood has the function of improving qi reception and relieving asthma, but the underlying mechanism is unclear and rarely reported. Therefore, this study explored the anti-asthmatic effect of the alcohol extract of agarwood produced by the whole-tree agarwood-inducing technique(Agar-Wit) in the asthma mouse model induced by intraperitoneal injection of ovalbumin(OVA) + Al(OH)_3 combined with intranasal administration of OVA and the mechanism, and compared the anti-asthmatic effects of agarwood induced with different methods. Firstly, the anti-inflammatory and anti-asthmatic effects of Agar-Wit agarwood in mice were evaluated based on the asthma frequency, lung tissue injury, and peripheral inflammatory white blood cell(WBC) count and eosinophil count. Then, the levels of interleukin-1β(IL-1β), IL-17, and IL-10 in serum of mice were detected by enzyme-linked immunoassay(ELISA) and the expression of inflammation-and apoptosis-related genes in tissues was measured by reverse transcription polyme-rase chain reaction(RT-PCR) so as to preliminarily explore the anti-asthmatic mechanism. RESULTS:: showed that the alcohol extract of Agar-Wit agarwood significantly reduced asthma frequency, relieved pathological injury, improved peripheral WBC count and eosinophil count, decreased the levels of inflammatory cytokines IL-1β and IL-17, elevated the level of anti-inflammatory cytokine IL-10, and down-regulated the mRNA expression of IL-1 R, tumor necrosis factor receptor R(TNFR), nuclear transcription factor-kappa B(NF-κB), Bax, and caspase 3, but had no significant influence on the expression of high-mobility group box 1(HMGB1) protein, caspase 8, and Bcl-2. The effect of Agar-Wit agarwood alcohol extract was better than that of wild agarwood alcohol extract and alcohol extract of agarwood induced with the burning-chisel-drilling method at the same dose. In conclusion, Agar-Wit agarwood can significantly alleviate inflammation and asthma, which is related to its anti-inflammation and anti-apoptosis activity.
