本研究工作的目的是通过功能基因组分析的技术平台，探讨微囊藻毒素诱导肝组织细胞凋亡的信号转导通路，以便在此基础上，进一步深入研究该毒素对凋亡功能基因在转录、表达、调控水平上的影响，及由此引发的生物学效应；揭示微囊藻毒素的凋亡毒理机制，同时发现新的生物标记物。

The clavacin toxin generally exists in the concentrated apple-juice for export, especially in the middle and later period of the squeezing season, the risk the content of the clavacin toxin exceeds the standard is very big in the case that the decay ratio of the raw material of the apple is higher. In the practical examination and verification of HACCP food safety management system, people found various methods and paths for controlling the clavacin toxin in the production of the concentrated apple-juice, b...

棒曲霉毒素在出口浓缩苹果汁中普遍存在，特别是在榨季的中后期原料苹果的腐烂率较高时其质量分数超标的风险很大，在HACCP食品安全管理体系审核实践中，发现浓缩苹果汁生产过程中，控制棒曲霉毒素的方法和途径有多种，但不论哪一种或多种组合应用都应关注原料果的品种、生产季节和储存温度，因为这些因素是降低棒曲霉毒素质量分数和生产成本的关键因素。

Antinociception and VGSC-modulation of BmK IT2 and BmK AS—1. The results from nociceptive flexion reflex and plantar radiation heat showed: BmK IT2 (a depressant insect-selective neurotoixn) and BmK AS-1 (a new-type β-1ike neurotoxin) have significant antinociceptive effects on rat peripheral nerve system. The antinociceptive effects of BmK IT2 on the carrageenan-inflamed rats were significantly stronger than those on the normal rats. Whole-cell patch-clamping showed: Both TTX-S and TTX-R Na〓 currents induced from rat DRG neurons were significantly inhibited by BmK IT2 and BmK AS—1, and BmK IT2 was more sensitive to TTX-R than TTX-S component. All the results suggested: the peripheral antinociception of BmK IT2 and BmK AS—1 might be attributed to the inhibitory effects of them on the TTX-S and TTX-R Na〓 channel located on the peripheral ends of rat DRG neurons with small diameter.
