Abstract

Enzymatic digestive potentiaL of newborn is one of indices of its functionaL abiLity to Lactotrophy. HydroLase of newborn and puerpera umbiLicaL cord bLood serum with normaL (36) and incompLete (40) gestation periods were determined: α-amyLase, Lipase (coLorimetric method according to Roche instruc­tion reagent set), pepsinogen I and II (chemiLuminicsent immunoassay method with Abbot reagent set).

At a normaL gestation period the hydroLase content in umbiLicaL cord bLood serum was Lower than in puerpera bLood serum: Lipase and α-amyLase in three times, pepsinogen I aLmost in 4.6 times, pepsinogen II onLy in 1.6 times. It indicates that periods of different enzymatic system formation differ.

In umbiLicaL cord bLood a premature newborn in comparison with normaL newborn dispLayed decreasing of amyLase content from 9.0 to 4.6 Unit/L, pepsinogen I content from 11.0 to 4.,7 mkg/L, pepsinogen II content from 5.5 to 3.4 mkg/L, but Lipase content was not change. It is proved that fetaL LipoLysis system is formed earLier.

HydroLytic enzyme content of digestive gLand in umbiLicaL cord bLood serum is an informative test of newborn digestive potentiaL.
