reference electrode (3). The ionized calcium concentration of sequential retentates prepared by ultrafiltration of a human control serum increased with increasing protein concentration in a way consistent with Donnan theory (4, 5) when the analyzers’ standard reference-electrode liquid junctionswere used; however, the ionized calcium in the same retentates declined slightly with increasing prot...

Human placental growth hormone in normal and abnormal fetal growth

Human placental growth hormone (PGH), encoded by the growth hormone (GH) variant gene on chromosome 17, is expressed in the syncytiotrophoblast and extravillous cytotrophoblast layers of the human placenta. Its maternal serum levels increase throughout pregnancy, and gradually replaces the pulsatile secreted pituitary GH. PGH is also detectable in cord blood and in the amniotic fluid. This plac...

Gelatin as a Source of Growth-Promoting Substances for Bacteria.

In the course of studies on the nutritional requirements of some of the more exacting bacteria it wase found that the addition of certain brands of gelatin to a simplified synthetic medium caused growth of a number of bacteria which were unable to develop in the same medium without the gelatin. The use of gelatin in amounts ordinarily employed for culture media produced results which were compa...
