vt8 pathology Flashcards
serous
protein rich, few cells present, light yellow (straw color) transparent
hemorrhagic
red, red blood cells
serossanguinas
serous fluid and small amount of blood
purulent aka supprative
neutrophils and bacteria
PUS
mucopurulent
mucus from respiratory and urogenital tracts
fine needle aspirate
used to gather cells from skin masses and lymph nodes
collection of diseased tissue
needle core biopsy incicional biopsy excisional biopsy
10 % formalin formalin; tissue 10:1
tissue thickness < 1 cm
if mass > 1cm in thickness, slice
CSF collection (cerebral spinal fluid
RTT for collection and spinal needle
general anesthesia, lateral recumbency, skull and spine alligned along edge of table
head flexed at 90 degree angle to spine
arthrocentesis
sites of collection: carous/tarsus, stifle, elbow
sedation required, synovial fluid
abdomniocentesis
direct large bore needle (20) g directed into the abdominal cavity and the fluid aspirated
thoracoventesis
air in throx+pneumothorax
blood in thorax: hemothorax
fluid in thorax; pyothorax
degenerative
disease that occurs due to cell death typically due to animal aging
osteoarthritis canine cognitive dysfunction
endocrine
imbalance in bodys hormones hypo: under hyper: elevated
metabolic
results from organ failure
neoplasia
anormal new growth of tissues; multiplication of new cells is uncontrolled rapid and progressive
malignant
cancerous
benign
not cancerous
acute
shor duration severe course
chronic
long duration extended onset
subclinical
no observable signs of disease
latent
carrier of disease not showing clinical signs can be a source of infection for others
tissue repair/healing
inflammation regeneration organization
tissue repair/healing phases
removal debridement
repair scar formation
regeneration depends on tissue type
acute inflamation
erythema heat pain edema loss of function
causes: infection , immune response, hypersensitivities, physical trauma , necrosis
acute inflammtaion phases
vascular phase: change in blood vessel dimater
exudative phase: fluid leakage from blood vessel
cellular phase: leukocytes emigrate to site of injury
Vascular phase
white line :transient lasts a few seconds
hyperemia: extended lasts several minutes to many days
exudative phase
protein rich fluid escapes from the blood vessles into the surrounding tissue
acute inflammation systemic effects
pyrexia, changes in blood cells, pain, depression anorexia nausea, muscle pain, weight loss
scar tissue
granulation tissue
