To remove or wall-off the cause of the injury

To repair or replace the damaged tissue

3

What are the clinical manifestations of inflammation

A

Heat, Redness, Swelling, Pain, Loss of function

4
Q

What chemicals are released after cell damage

A

Prostaglandins

Leukotrienes

Thromboxanes

Histamine

Cytokines

5
Q

What are the first responses in Inflammation?

A

Increased blood flow/perfusion

Dilution of offendng agent (serum)

Fibrin to immobize agent

Phagocytic cells to get rid of agent

6
Q

Cyclooxygenase

A

An enzyme in the inflammatory cascade

Responsible formaking prostaglandins

7
Q

Cyclooxygenase has two forms. What are they?

A

Cox-1: maintains physiologic functions (renal blood flow, stimulate gastric mucosal protection) GOOD

Cox-2: mediates inflammation and pain BAD

8

Q

What areas of the brain are responsible for pain interpretation?

A

Crebrum

Thalamus

Medulla

11
Q

How can fever be an important indicator of disease?

A

Chemical mediators released by damaged cells can cause fever.

12
Q

How can a fever serve a purpose?

A

Destruction of the invading virus or bacteria by heat activation.

13
Q

What is a pyrogen?

A

A substance which can induce fever

14
Q

Where do exogenous pyrogens come from?

A

From outside the body - viruses and bacteria

15
Q

Where do endogenous pyrogens come from?

A

From inside the body - chemical mediators (protaglandins)

16
Q

How do NSAIDs work

A

Work by inhibiting cyclooxygenase

17
Q

What are some adverse effects to NSAIDs

A

GI ulceration and bleeding due to the loss of the normal mucus coating of the stomach

Nephrotoxicity

Bone marrow suppression

Bleeding tendencies

Hepatoxicity

18
Q

Bleeding disorders

Currently taking steroids or other NSAIDs

Horses

Off-label in canine and feline

23
Q

What is Etodolac (Etogesic) used for?

A
