Drug therapy is warranted for many dogs with liver disease. Glucocorticoids (âsteroidsâ) have been used to prolong survival times in dogs with liver disease due to their anti-inflammatory and immunosuppressive properties, although their use and appropriate dosage protocols are somewhat controversial.
chiasma. pl. chiasmata [L., Gr.] chiasm; in genetics, the points at which members of a chromosome pair are in contact during the prophase of meiosis and because of which recombination, or crossing over, occurs on separation.
The term âchiasma,â which comes from the Greek, refers generally to an intersection or crossing. This term is also used in anatomy to refer to bundles of nerves at the point of intersection, like the optic chiasm, where the optic nerves cross each other.t the chiasma, the chromatids can exchange genetic information, resulting in new combinations of genetic material. When the chromatids separate and become sister chromosomes, they will contain a different mix of genetic material than their parent chromosomes.
