[Diagnosis of fetal distress during labor with the aid of the Hammacher cardio-tocographic score and fetal pH determination].

The authors study the value of the Hammacher tocographic scoring system in the diagnosis of fetal distress in labour. This score gives equal value to three components of the fetal heart rate: the base line, transient variations (dips) and fluctuations (oscillations). There is a statistically very significant (p less than 0.001) relationship between the cardio-tocographic score and the fetal pH as has been found in 106 labours with a coefficient of correlation of 0.67. The score can only be carried out usefully when a "beat to beat" to heart rate is registered and when this is not influenced by the administration of drugs to the mother. The score has been demonstrated to be particularly useful in the diagnosis of fetal distress when the membranes are still intact.

APUD-like cells in the primitive gut of a 27 day old human embryo.

A 27 +/- 1 days old human embryo arising from an ectopic pregnancy was incubated with 3,4, L-dihydroxyphenylalanine (L-DOPA) to investigate whether cells of the gut primordium have at this early stage of development, the ability to take up the amine precursors. We could observe that a few cells exhibiting greenish fluorescence were located in the epithelium wall of the fore gut. Most of them were situated in contact with the basal lamina and possessed a long apical process extending over towards the gut lumen. The uptake of amine precursor, the morphology and the location of these cells strongly suggest that they represent the gut endocrine precursor cells of the human embryo.
