Glycoconjugate expression changes during Rana dalmatina early development.

Glycoconjugates are generally involved in cell adhesion and morphogenetic movements. To investigate their distribution and expression changes during amphibian development, several FITC-or HRP-labeled lectins were used in Rana dalmatina embryos and larvae. During gastrulation, WGA, ConA, HPA, GSA-I, PNA and RCA-I labeled either the envelopes on the perivitelline space-contained substances, while ectodermal cells and/or extracellular matrix were mainly labeled by WGA, GSA-I, DBA and LTA.

[Blood levels of cortisol and prolactin. Are they indices of the degree of protection against surgical stress?].

The paper evaluates the level of analgesic protection by assaying cortisol and prolactin levels in two groups of 20 patients each undergoing general anesthesia using two different techniques: TIVA with propofol and fentanyl, and BPN-nitrous oxide. The results showed that TIVA caused a very slight increase in residue cortisol which was, however, within normal limits. With BPN-nitrous oxide anesthesia there was a greater increase in cortisol, reaching a statistically significant level in blood collected one hour after the end of surgery.

[Intravenous anesthesia using propofol in surgical interventions in day hospital routines].

Having illustrated the importance of extending surgical treatment into day hospital situations, the paper underlines the need for anesthetics with short-term effects. Two groups of 30 patients were included in the study and underwent anesthesia in day hospital using Propofol or Tiopentone-Enflurane. The results reveal comparable respiratory and hemodynamic effects for the two techniques, but Propofol is more reliable in terms of the lesser side-effects caused and above all the speed of the patient's psycho-physical recovery.
