[Study of flos lonicerae in local herbs and other areas by FTIR spectrum].

The FTIR spectra of flos lonicerae(FL) in four different areas are analysed by FTIR and the comparison of local(Henan) FL and FL in other areas is also studied. The result shows that the FL in different areas have the different content of main effective substance, so their absorption frequency and form in FTIR spectra are different as well. There is an obvious difference between Sichuan and local FL in wave number and form.

Anti-abortive effect of Radix scutellariae and Rhizoma atractylodis in mice.

The objective of this study is to investigate the significance of natural killer (NK) cells and interleukin-2 in uterus in the early embryo loss (or resorption), and to elucidate the immunological modulation of maternal-fetal interface with Chinese herbal medicine Radix scutellariae (huang qin) and Rhizoma atractylodis (bai zhu). Lipopolysaccharide (LPS) was given via the tail vein to induce abortion in mice at day 7 of gestation. Uterine NK cells and IL-2 contents were analyzed by immunohistochemistry and enzyme linked immunosorbent assay (ELISA), respectively.
