摘要:为了探讨森林康养对人体免疫功能的影响,筛选12名健康志愿者于2019年7月上旬在吉林省长白山二道白河区森林康养基地进行为期“3天2夜”的康养活动。康养前后,利用流式细胞仪检测外周血CD56+ NK细胞和CD3+淋巴细胞的百分比,通过酶联免疫吸附试验(ELISA)法测定血浆中颗粒酶、颗粒溶素和穿孔素的浓度。研究结果发现,长白山二道白河区夏季“3天2夜”的森林康养活动显著提高了外周血CD3+淋巴细胞和CD56+NK细胞的百分比(P<0.05),同时血浆中穿孔素、颗粒酶和颗粒溶素的水平增加(P<0.05)。由此可见,森林康养活动在一定程度上可提高人体免疫功能。

Abstract: To explore the effect of forest therapy in the summer on human immune function in Baihe District of Changbai Mountain, Jilin Province, the study screens and selects 12 healthy volunteers to have a three-day and two-night forest therapy there. The percentages of CD56+ NK cells and CD3+ lymphocytes in their peripheral blood are monitored using flow cytometry, and the concentrations of Grs, GNLY and perforin in plasma are tested using Elisa assay before and after forest therapy. The results show that compared with the pretest conditions, the forest therapy produces a significant increase in percentage of CD3+ lymphocytes and CD56+ NK cells (P<0.05), and also an obvious increase in the perforin,GrA, GrB and GNLY levels in plasma. The results suggest that forest therapy activities can significantly increase human immune function to a certain extent.

森林康养是目前公认的缓解压力的有效途径之一[1],相关学者通过研究发现:森林康养过程中自然杀伤细胞(Natural Killer Cell,NK)的数量和活性均增加[2-3];此外,森林康养还可缓解焦虑、愤怒等不良情绪。森林康养在日本和德国非常受欢迎,甚至作为药物的一部分进入国家医疗保险领域。有研究证实森林康养具有提高机体免疫功能的效应,主要由细胞毒性T淋巴细胞(Cytotoxic T Lymphocyte,CTL)和NK细胞完成,因为这些细胞内均含有穿孔素(Perforin)、颗粒酶(Granzyme,Grs)和颗粒溶素(Granulysin,GNLY)[4]。当淋巴细胞识别靶细胞后,颗粒酶会迅速释放到淋巴细胞—靶细胞突触中,通过多种途径诱导细胞死亡;穿孔素有助于颗粒酶进入靶细胞胞质发挥作用,该途径是CTL诱导细胞死亡的主要机制;颗粒溶素对多种微生物和肿瘤具有广泛的细胞溶解活性[5]。……
