Objective: To investigate the effects of different processing methods(steeping, boiling) and different adjuvants(alum, ginger, bile) on contents of amino acid and part of inorganic elements in Arisaema amurense Maxim.. Methods: The amino acid was determined by HPLC, and the inorganic elements were determined by AAS. Results: The total content of amino acid was the highest in raw Arisaema amurense Maxim. and the lowest in Arisaema amurense Maxim. processed with bile, wherease it was similar to other processed samples. The inorganic element content changed after it was processed. Conclusion: The long rinse is the key factor of losing amino acid in Arisaema amurense Maxim. after being processed. The content of inorganic element in adjuvants is the key factor of their content changes in Arisaema amurense Maxim. after it is processed.

Objective To observe the inhibitory effect of caspase\|3 mRNA antisense oligodeoxynucleotides (ASODN) on the apoptosis of HL\|60 cells, and to screen the effective ASOND. Methods By means of the lipofectimine\|mediating transfection, caspase\|3 mRNA ASODNs of four different sequences were introduced into HL\|60 cells followed by ? irradiation.The gel electrophoresis was performed for the DNA ladder, Hoechst 33258\|propidium iodide fluorecent staining for the percentage of apoptotic cells, and FCM for quantitative analysis of apoptosis. Results When HL\|60 cells were transfected with caspase\|3 mRNA ASODNs targeting 5'noncoding region (sites -62 to -46) and initiative coding region (sites -1 to 16) at the final concentration of ≥3?? mol/L, the DNA ladder was not detected with the gel electrophoresis, nor was the apoptotic peak found with FCM. Fluorescent staining analysis showed that the percentage of apoptotic cells was significantly lower than that in the control groups including non\|transfection group and mismatched oligodeoxynuleotide group ( P
