Model PGR-1 is high performance, pressure loaded diaphragmtype, flow-to-open pressure reducing regulator. Design includes an internal pressure balancing piston-cylinder that provides high flow capacity. The internal trim design allows the same basic unit to cover a broad range of pressure settings.

胃蛋白酶原 (pepsinogen，PG)是一种具有消化功能的内切蛋白酶，是由375个氨基酸组成的单链多肽，属于天冬氨酸蛋白家族。 人胃蛋白酶原可根据在琼脂凝胶电泳下的迁移率由快至慢分为pgl-pg7七种同工酶原，其中pgl-pg5有共同的免疫原性，也叫PG I；pg6到pg7迁移率较慢，也叫PG II。 在组织体内，PG I和PG II的细胞来源和组织分布各不相同 。 有研究表明PG I水平降低是胃病发生与发展的可靠标志。 国外也有人把低水平血清PG看作是胃病发生与发展的标志，其通过 …
