Description
Book SynopsisCANINE AND FELINE LIVER CYTOLOGY Specialist reference with practical guidance on liver pathology in a clinical and anatomical context Canine and Feline Liver Cytology is a practical and highly illustrated manual with detailed descriptions of cytological features of hepatic diseases and numerous high-quality illustrations to aid in reader comprehension. The primary aim of the text is to describe the correlation of cytological findings with pathological processes in order to provide useful information to clinicians in management of hepatic diseases. Canine and Feline Liver Cytology includes information on: General bases for interpretation of hepatic cytology, covering limits of cytology, value of cytology for a definitive diagnosis, and relationship with clinical dataA specific reversible injury to hepatocytes, covering hepatocellular swelling, steroid induced hepatopathy, hepatocellular steatosis, and feathery degenerationIrreversible injury to hepatocytes, covering necrosis and apopto
