Microvascular Architecture of the Lingual Papillae in Rabbits.

Extract

The comparative morphology of the tongue microvasculature has been studied in different animals, such as in man (Okada et al, 1993, Matsukawa and Okada, 1994), rats (Nagato et al., 1989, Ohshima, et al, 1990, Selliseth and Slvig, 1993), dogs (Kishi et al, 1986, Kishi et al 1988), goats(Scala et al, 1992), monkeys (Patterson, et al, 1992, Okada et al, 1993, Matsukawa and Okada, 1994), marmosets (Okada et al, 1993, Matsukawa and Okada, 1994) and shrews (Okada et al, 1993, Matsukawa and Okada, 1994), but apparently none in rabbits. The disposition of the blood vessels of the rabbit's lingual papillae were studied by injecting them with Mercox resin and posterior corrosion, thus obtained microcorrosion casts were observed in the scanning electron microscope.

Male and adult rabbits were used to obtain our models. After perfusion with heparin 0,1M, pH 7.4 and glutaraldehyde, both in the same buffer, the vessels were filled as reported above.
