Vitamin D Status: A Different Story in the Very Young versus the Very Old Romanian Patients.

Background: In Romania (latitude 48°15'N to 43°40'N), vitamin D supplementation is common practice mostly in infants 0-1 year old. No published information is available regarding epidemiological data on vitamin D status in the Romanian population for a wide age range and geographical territory. In this context, we aimed to evaluate the seasonal and age variation of vitamin D status in a large Romanian population.

Vascular morphometry and micrometry of the orbital region of the human optic nerve.

The study aims at providing data on the vascular morphometry and micrometry of the orbital region of the human optic nerve. The disposition of the microcirculatory trunk in the orbital region has been studied on 40 samples taken post-mortem, as well as on 10 pieces from subjects having undergone enucleation. Histological specimens were prepared from the optic nerves using eosinhematoxylin dye-staining, the Romhany-Bârzu staining and the Gomory trichromic staining.
