[Hematopoietic cells of fetal liver. 1. Effect of growth factors of varying origin and activity of granulocyte-macrophage progenitor cells].

The liver is the leading hemopoietic organ of 5-22-week embryo and fetus. Hepatic hemopoiesis activity is assessed by concentration, total count and proliferative capacity of granulomonocytic cell precursors (GMCP). Cloning efficacy (GMCP CE) in the liver of 7 fetuses of 16-22 weeks of gestation was evaluated in vitro.

[Total synthesis and properties of prostaglandins. XIV. Amide derivatives of 3alpha-tetrahydrofuranyloxy-5-hydroxyimino-2beta- (3alpha-tetrahydrofuranyloxy-trans-1-octenyl)-cyclopentane- 1alpha-acetic acid].

Several novel prostaglandins containing an amide group in the alpha-chain have been prepared by the mixed carbonic anhydride method from 3 alpha-tetrahydrofuranyloxy-5-hydroxyimino-2 beta-(3 alpha- tetrahydrofuranyloxy-trans-1-octenyl)-cyclopentane-1 alpha-acetic acid and omega-amino acids with a linear chain of varying length (CH2-group number from 1 to 7). The physico-chemical properties of the title compounds were studied.
