RESUMEN
OBJECTIVE: To compare the composition and content of Arnebiae Radix and the stem residues. METHODS: TLC and HPLC were used to identify Arnebia, ultraviolet-visible spectrophotometry was used to determine the content of hydroxy naphthoquinone total pigment in Arnebia, HPLC was used to determine the total content of /3-P'-dimethyl acrylamide Aka Ning and shikonin. RESULTS: The number of spots of Arnebia Radix was consistent with that of the stem residues in 10 batches of medicinal materials, the former was larger and deeper in color. Their features of fingerprint are the same,at the same retention time,the peak area of radix was larger; The average content of hydroxy naphthoquinone total pigment was 3.631% in the radix, and 1.516% in the stem. The total content of beta-beta'-dimethyl acrylamide Aka Ning and shikonin in the radix and the stem were respectively 0.89% and 0.309%. CONCLUSION: The ingredients in the radix and the stem residues are the same, but the contents of root of the total pigment content of hydroxyl-naphthoquinone, beta-beta'-dimethyl acrylamide Aka Ning and shikonin are twice higher than those of the stem residues.

OBJECTIVE: To study the using of the method in vitro and in vivo of lasting time of ciliary movement in ligustrazine, synthetic borneol. METHODS: (1) Method in vitro-The lasting time of ciliary movement was observed with forty-fold optical microscope after dropping liquid medicine on exteacorporeal frog palate mucosa. Then mucosa was cleared. It was observed whether the ciliary movement was recovered and the lasting time was recorded from recovering to stopping once again. (2) Method in vivo-Liquid medicine or normal saline was dropped on frog palate mucosa by contacting thirty minutes. Then mucosa was cleared. The lasting time of ciliary movement was observed with forty-fold optical microscope by separating palate mucosa. RESULTS: Relatively percentage of lasting time of ciliary movement of ligustrazine in vitro and in vivo was 9.8%, 87.3%; The relatively percentage of synthetic borneol in vitro and in vivo was 9.3%, 89.5%. CONCLUSION: The method in vitro and in vivo of lasting time of ciliary movement can be the one of the selecting ways of Chinese drug's toxicity of nasal mucosa, and it have virtues and defects respectively. Ligustrazine, synthetic borneol have significantly toxical effect on exteacorporeal lasting time of ciliary movement.
