At labeled dose (1.1 mg/kg) given IV, detection time was found to be ...
The third gene array shows a deuteranopia genotype; the fourth shows a normal color vision genotype. When unequal recombination happens with breaks between the genes (depicted by blue lines), a gene can be essentially deleted from one of the chromosomes. This gene deletion leads to protanopia or deuteranopia (congenital red–green dichromacy).
Up-and-down procedure (or method) for toxicology tests in medicine is an alternative to the LD 50 test, in which animals are used for acute toxicity testing. [ 1 ] [ 2 ] It requires fewer animals to achieve similar accuracy as the LD 50 test because animals are dosed one at a time. [ 3 ]
Side effects from intra-articular administration can include joint pain, swelling, lameness, and, rarely, infection of the joint. Intramuscular injection can cause dose-dependent inflammation and bleeding, since PSGAG is an analogue of the anticoagulant heparin. [4] In dogs, this may manifest as bleeding from the nose or as bloody stools. [7]
Horses in hard training may need a vitamin E supplement, as their requirements are higher than horses in more moderate work.
