The Draize test is an acute toxicity test devised in 1944 by Food and Drug Administration (FDA) toxicologists John H. Draize and Jacob M. Spines. Initially used for testing cosmetics, the procedure involves applying 0.5 mL or 0.5 g of a test substance to the eye or skin of a restrained, conscious animal, and then leaving it for a set amount of time before rinsing it out and recording its effects.
"Typically, animal tests for cosmetics include skin and eye irritation tests where chemicals are rubbed onto the shaved skin or dripped into the eyes of rabbits; repeated oral force-feeding studies lasting weeks or months to look for signs of general illness or specific health hazards, such as cancer or birth defects; and even widely condemned ...
A few days after the injection, the animal would be dissected and the size of her ovaries examined. The rabbit test became a widely used bioassay (animal-based test) to test for pregnancy. The term "rabbit test" was first recorded in 1949, and was the origin of a common euphemism, "the rabbit died", for a positive pregnancy test. [4]
Male rabbits are called bucks; females are called does.An older term for an adult rabbit is coney, while rabbit once referred only to the young animals. [1] Another term for a young rabbit is bunny, though this term is often applied informally (especially by children and rabbit enthusiasts) to rabbits generally, especially domestic ones.
The test is a dye tracing method. The fluorescein dye also reappears in the patient urine, causing the urine to appear darker, and sometimes orange. [2] It can also cause discolouration of the saliva. Fluorescein angiography is one of several health care applications of this dye, all of which have a risk of severe adverse effects.
This 'Where's Waldo?'-style game will be the one responsible for your early onset eyesight loss (joking, but do be careful how close your face is to the screen).
New Zealand rabbits have a broad, muscular, and deep body of medium length, with well-rounded haunches. [3] The ears stand straight up rather than being lopped. Fur is of normal length and "flyback," [4] which means that when brushed in the wrong direction, it immediately returns to the original position. New Zealands are medium to large rabbits.
Video-oculography (VOG) is a non-invasive, video-based method of measuring horizontal, vertical and torsional position components of the movements of both eyes (eye tracking) using a head-mounted mask that is equipped with small cameras. VOG is usually employed for medical purposes.
