“…Therefore, the present observation indicates that preterm infants, especially with very low birth weight, may have several disadvantages for keeping Zn status within normal limits due to less accumulated amounts of Zn during the shortened gestation period, poor availability of dietary Zn or delayed maturation of Zn homeostasis. Similar to ours, the first possibility was suspected by Michie and Wirth (1978) in their study. The second possibility was supported by animal experiments by Ghishan and Sobo (1983).…”

“…In attempting to define intravenous trace element requirements, most workers measure serum or plasma trace element concentrations, although this does not necessarily reflect the nutritional adequacy of the diet (Mills, 1974;Mertz, 1975). Thus Michie and Wirth (1978) found no significant change in plasma zinc concentrations in premature babies during the first two weeks of parenteral nutrition using a "zinc free" infusate. Shaw (1973) adopted an alternative approach to defining the essential element requirements of small premature infants, one which does not rely on the measurement of serum or blood element concentrations.…”

“…τα αποθέματα της βιταμίνης Α στο ήπαρ αυξάνονται(145). Σε μελέτες in vitro διαπιστώθηκε ότι η α-τοκοφερόλη αναστέλλει την δράση του ηπατικού ενζύμου υδρολάση του εστέρα της βιταμίνης Α (146), οπότε επί ανεπάρκειας της βιταμίνης Ε αυξάνεται η υδρόλυση των εστέρων της βιταμίνης Α του ήπατος, με αποτέλεσμα την ελάττωση των αποθεμάτων της βιταμίνης Α. Επίσης, επί Πρόωρα νεογνά που τρέφονται με παρεντερική διατροφή, παρουσιάζουν συχνά έλλειψη ψευδάργυρου(153), που σε μερικές περιπτώσεις συνοδεύεται και από δερματικές εκδηλώσεις(154). Για τον λόγο αυτό, οι συνιστώμενες ποσότητες ψευδάργυρου στην παρεντερική διατροφή των πασχόντων προώρων(155), πιθανόν να πρέπει να αυξηθούν(137).…”
