In vitro autoradiographic localization of vasoactive intestinal peptide (VIP) binding sites in the rat central nervous system.

This paper describes the autoradiographic distribution of VIP binding sites in the rat central nervous system using monoiodinated 125I-labeled VIP. High densities of VIP binding sites are observed in the granular layer of the dorsal dentate gyrus of the hippocampus, the basolateral amygdaloid nucleus, the dorsolateral and median geniculate nuclei of the thalamus as well as in the ventral part of the hypothalamic dorsomedial nucleus.

[Vip in human neonates and infants. As measured by radioimmunoassay and radioreceptorassay (author's transl)].

The Vasoactive Intestinal Peptide (VIP) was assayed in the gut of human neonates and premature infants immediately after death or surgery. In these conditions, values ranged between 150 and 740 ng/g of bioled tissue. The implication of VIP in Vermer-Morrison syndrome is further assessed by the correlation between clinical symptomatology and plasma VIP levels. The immunoassayable VIP (IA-VIP) extracted from normal gut or tumor is shown to fully interact with specific receptor for VIP in liver. This fact suggests the biological potency of IA-VIP.

Lamellar keratoplasty with the Barraquer microkeratome.

Lamellar keratoplasty was performed in 17 eyes: 6 with corneal opacities following epidemic keratoconjunctivitis, 3 with herpes keratitis, 2 with anterior corneal dystrophies, and 6 others. The Barraquer microkeratome was used for the resection in both the host and the donor. A technique is described to correct major disparities in diameter between the bed and the donor disc. In eyes with vision limited only by corneal diseases (11), the best postoperative spectacle corrected visual acuity was 20/25; the mean postoperative spectacle corrected visual acuity for the 11 eyes was 20/40.
