Effects of Daturae Flos and Daturae Semen Extract on the Immunocyte Response in Mice

만타라화(曼陀羅花) 및 만타라자(曼陀羅子) 수추출물(水抽出物)이 마우스의 면역세포기능(免疫細胞機能)에 미치는 영향(影響)

This study was undertaken to test the effects of Daturae Flos(DF) and Daturae Semen(DS) on the cellular and humoral immune responses, and the functions of the cells involved in immunoinflammation. Both extracts decreased the activity of superoxide dismutase, and the decrease was greater in the mouse group which was treated with DS. Both extracts decreased the phagocytic activity as measured by assessing the number of the latex particle within the phagocyte after incubation of peritoneal macrophages with fluorochrome-labelled latex particle and decreased natural killer cell activity as measured by enumerating the viable YAC-1 cells after treatment of target cells with splenic natural killer cells. Both extracts also decreased the cell-mediated immunity in vivo as assessed by measuring the ear thickness after sensitization and challenge with dinitrofluorobenzene, however, had no effects on the humoral immune responses as measured by checking hemolysin and hemagglutinin titers after immunization with sheep red blood cells(SRBC). Extracts of Semen caused decrease in the number of rosette forming cells between the splenic cells and SRBC. The results of this study suggested that both Daturae extracts could depress the immunoinflammation by affecting the various cell types involved in inflammation.
