Fluorophotometry of the animal eye
1996
: We assessed the usefulness of the Fluorotron Master fitted with a small animal adapter. We also discuss the measurement conditions for the tupai, which is a promising experimental mammal. A good concentration for measurements with this instrument ranged from 0.5 x 10(-6) to 1.0 x 10(-6) g/ml. A suitable time for fluorophotometry of the tupai was 30 min. after injection of fluorescein-Na, and a suitable dose of the fluorescein-Na was 2 mg/kg. We could do ultrafiltration for measurement of the protein unbound fluorescein concentration from a minimal sample of the blood using a hematocrit tube, and thus could reduce the deleterious effects of blood sampling on the animal. This instrument is useful for the estimation of the blood-ocular barrier permeability of animal models.
