The in vitro effects of Gln49-PLA_2 were examined using the chick biventer cervicis nerve muscle preparation. Gln49-PLA_2 caused a dosedependent blockade of neuromuscular transmission. The time required to cause 50% blockade was about 150 min at the highest concentration 100μg/ml. This inhibition appeared to be presynaptic in origin as evidenced by the lack of effect of toxin on responses to exogenous acetylcholine in the non-stimulated BCp.

In fact, there is little pump of the fluid loss, which makes the operation of pumps can not achieve 100% efficiency, as these fluids are used to on both sides of bearing and gear lubrication, and the pump body is also not possible with no gap, it can not be so that 100% of fluid discharged from the export, so a small amount of fluid loss is inevitable.

实际上，在泵内有很少量的流体损失，这使泵的运行效率不能达到100％，因为这些流体被用来润滑轴承及齿轮两侧，而泵体也绝不可能无间隙配合，故不能使流体100％地从出口排出，所以少量的流体损失是必然的。

As the introduction of today's world the most advanced production line in Germany Spunlace its opening; Qing; loose, roll out their networks, combing, Spunlace machine are collected well-known public house Spunlace nonwoven equipment length, equipment efficiency tends to optimization, a powerful to ensure that the equipment suitable for the diversity of species, can produce 40 ~ 250g; m2 various Spunlace cloth (including synthetic leather base cloth, filter materials, hygiene materials, etc.).
