Q
  1. How does the Siberian hamster differ from the Syrian hamster physiologically?
A
  1. Siberian is half the size, has furred feet, has coat color change to white in the winter vs. dark in the summer in the wild, and has large litters year around (vs. variable seasonality seen in Syrians).

Q
  1. Select the following true statement about a drug’s hepatic extraction ratio:
    a. A drug with a hepatic extraction ratio of close to 1 means that hepatic blood flow has little to no effect on clearance of the drug
    b. A drug with a hepatic extraction ratio of close to 1 means that drug clearance is related to and highly dependent on hepatic blood flow
    c. Hepatic extraction ratio has nothing to do with hepatic drug clearance.

Q
  1. Select the following true statement about fasting prior to Ketamine/Xylazine (KX) anesthesia in rats:
    a. Fasting is shown to have a profoundly positive effect on the quality of KX anesthesia in rats.
    b. Fasting prior to KX anesthesia in rats is detrimental to the rat.
    c. Fasting prior to administration of KX anesthesia has not been shown to affect quality or variability of KX anesthesia in the rat
    d. Fasting rats is necessary prior to inhalant anesthesia, but not prior to KX anesthesia
A

C

18
Q
  1. Why are volatile gas anesthetics contra-indicated for ischemia-reperfusion studies?
A
  1. Volatile anesthetics can protect tissues (including heart, brain, kidney, lung & liver) from ischemia-reperfusion injury.
19
Q

For the acetic acid test, what substance provided the most increase in nocioceptive threshold in Xenopus laevis?

A

Flunixin meglumine at 25 mg/kg

20
Q

The AAT and Hargreaves tests both measure response to what type of stimuli?

 	a. Visceral pain
 	b. Cutaneous stimulation of afferent fibers
A

b. Cutaneous stimulation of afferent fibers

21
Q

Describe the Hargreaves apparatus.

A

The Hargreaves apparatus is used to measure thermal nociceptive threshold. It consists of a glass chamber though which a radiant heat source is focused on an area. In this case, frogs were placed in the chamber, and an infrared intensity was focused on the inner thigh. The time from activation of the thermal stimulus to withdrawal response was recorded as the thermal nociceptive threshold.

Q

T/F. This study highlights the importance of performing PK studies prior to extra label drug usage.

A

True

34
Q

T/F. Cefovecin should not be used in NHPs due to high incidence of adverse effects noted in these species.

A

False

35
Q

T/F. According to this study, the use of long-acting antibiotics in NHPs is generally discouraged.

A

False

36
Q
  1. What types of sweat glands are found in the paw pad of dogs?
A
  1. Eccrine glands: an unbranched, tubular gland, limited to the footpad and the nose.

Q
  1. What type of innervation is associated with sweat glands, sympathetic or parasympathetic?
A

Sympathetic: acetylcholine is the neurotransmitter associated with the sweat glands.
