Document Summary
Incisional biopsy- you just take a small amount of mass and cytological examination: necropsy- examination after death, gross pathology, take some of the normal tissue and then take a sample of the abnormal tissue. Inflammation of the lung- pneumonia or bronchopneumonia: histopathology, an examination of tissue, hematoxylin and eosin stain, put on histology slides, usually looking for different proteins or viruses in the tissues. Immunohistochemistry: uses antibody/antigen activity to help view. Toxicology: toxic/o = poison, toxicosis- a diseased condition resulting from poisoning, sample submission, blood and urine, stomach contents. If an animal vomits: liver, kidney, and brain, areas were toxic components often accumulate. Causes blood not to clot (anticoagulant) type- bleeding. Choleocalciferol type (vitamin d) = soft tissue minerilzation (too much vitamin d, will cause the tissue to mineralize) Oxalate crystals jam up the kidney and the animal will go into renal failure.
