[Transitory hypothermia as early prognostic factor in term newborns with intrauterine growth retardation].

Introduction: According to numerous researches, transitory hypothermia is a part of the neonatological energetic triangle and represents a significant prognostic factor within morbidity and mortality in newborns with intrauterine growth retardation (IUGR), that are, due to their characteristics, more inclined to transitory hypothermia.

Objective: The aim of the study was an analysis of frequency of transitory hypothermia in term newborns with IUGR, as well as an analysis of frequency of the most frequent pathological conditions typical of IUGR newborns depending on the presence of transitory hypothermia after birth (hypoglycaemia, perinatal asphyxia, hyperbilirubinaemia and hypocalcaemia).

Methods: The study included 143 term newborns with IUGR treated at the Neonatology Ward of the Gynaecology-Obstetrics Clinic "Narodni front", Belgrade.

Reference values of capillary blood saturation in neonates and its difference from pulse oximetry.

Introduction: Haemoglobin saturation is an obligatory oxygen parameter in the assessment of neonatal oxygenation. Although, pulse oximetry is currently one of the major methods in the determination of haemoglobin saturation, capillary blood saturation is still present in the diagnostic process. As well known, haemoglobin saturation value of capillary blood is insufficiently accurate, but not as much as the difference in relation to the values determined by pulse oximetry.

Comparison of effects of endogenous and exogenous excitatory amino acids on Retzius nerve cells of the leech.

In this paper we examine the effects of L-aspartate, L-glutamate, and beta-N-oxalylamino-L-alanine (Lathyrus toxin) on Retzius nerve cells of the leech Haemopis sanguisuga. The goal was to compare the electrophysiological effects of endogenous vs. exogenous amino acids, known as potent neurotoxins, through the mechanism ofexcitotoxicity.
