The technology of culture of exogenetic NGF in vitro is qualified now, however, the exogenetic NGF cant get through blood-brain barrier and blood-nerve barrier because it is a kind of marcomolecular protein, thus its extensive application on clinic is limited, now, many scholors have turned their study direction to enhancing the content of endogenous NGF.

外源性NGF的体外合成技术已基本成熟，然而，外源性神经营养因子作为一种高分子蛋白物质不能通过消化道给药、不能通过血脑屏障和血神经屏障的问题阻碍了它在临床上的广泛应用，所以NGF在临床上并没有真正发挥出其营养神经的作用。

Compared with the traditional fusing filament, the restricting overloading protection PTC Thermistor reacts fast, contactless, flameless, noiseless and recoverable. Meanwhile, compared with the organic high molecule PTC Thermistor, the pottery restricting current PTC Thermistor of normal temperature changes little after numerous protection with a better performance of withstanding voltage. Additionally, it can resume steadily and has a good performance.
