Under the same concentration, tadalafil induce higher ratio of relation responses in the smooth muscles of CRF rabbit cavernosal strips, compared with papaverine and sodium nitroprussiate, with most significant difference occurring under the concentration indicators of 10-5 mol/L and 10-4 mol/L (P.01). Conclusions The effects of tadalafil on relaxation responses in CRF rabbit cavernosal strips highly depend on its concentration. The effect of tadalafil on relaxation responses in CRF rabbit cavernosal strips is better than that of papaverine and sodium nitroprussiate. Tadalafil may be an effective drug for treating CRF reduced erection dysfunction.

The mechanism of carbonization process of aluminate solution was analyzed thermodynamically. The results show that the internal reason of precipitation of Al3 in the process is its spontaneous nucleation caused by supersaturation of aluminate solution. The behaviors of SiO2 in the process are in accordance with that from published experiment, which implies that the content of product SiO2 from carbonization depends on its solubility but is not the result of absorption. The thermodynamic calculation for forming Na2O·Al2O3·2CO2· n H2O was achieved.

摘 要：为对高浓度铝酸钠溶液碳酸化分解过程中产品杂质含量的控制提供理论依据，分析了铝酸钠溶液碳酸化分解过程的热力学，认为该过程中Al3析出的真正机理是过饱和铝酸钠溶液的自发结晶；而基于分解过程中平衡浓度的热力学计算表明，在碳酸化分解过程中SiO2的变化规律与公认的三段变化规律一致，说明该过程产品中SiO2的含量取决于它在溶液中的平衡浓度，而非吸附所致；同时还分析了丝钠铝石的形成热力学。

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.
