After section of the corticospinal (CS) tract in adult rats, neutralizing Nogo-A with monoclonal antibodies leads to enhancement of axonal re-growth and compensatory sprouting, accompanied by increased motor recovery. The neutralization of Nogo-A represents a promising approach for therapy after lesion if its enhancement of functional recovery can be transposed to primates. - [Read Anti-Nogo-A Treatment Protocol]
The results of cytotoxicity tests in primary cultures of rat hepatocytes and in MDBK and McCoy cells can be used to predict the in vivo 4-wk maximum tolerated dose in rats and dogs. A correlation between in vitro cytotoxicity, as measured in this system, and LD50 values in rats and mice has also been established. - [Read In Vitro Prediction of the Maximum Tolerated Dose Protocol]
For all the transgenic or other mouse researchers out there who have had to explain why colony infections are not just bad for the welfare of the animals concerned, but may invalidate the ongoing studies as well. - [Read Natural Pathogens of Laboratory Mice and Rats]
