Effects of Houttuyniae Herba on Immune Responses and Histological Findings in Mice Bearing Pneumonitis

어성초추출물(魚腥草抽出物)이 폐렴유발(肺炎誘發) 생쥐의 면역반응(免疫反應) 및 조직변화(組織變化)에 미치는 영향(影響)

In order to investigate the preventive and therapeutic effects of Herba Houttuyniae, experimental studies on the immune response and histological findings were undertaken. The results of these studies were summarized as follows; Delayed type hypersensitivity and rosette formation rate were significantly increased compared with control group. Hemagglutination, hemolysin titer and NK cell activity were variable, not significantly against the control group. When observed on lung tissue recovery; experimental groups were shown to be significantly recovered as compared with the control group. From these results, it is suggested that Houttuyniae Herba promotes immune response and reduces the recovery time of pneumonitis and lung abscess from the histological viewpoint.
