Q

What is an important role of fibrinogen?

A

Fibrinogen plays an important role in platelet aggregation by linking activated platelets. Activated platelets express the integrin αIIb β3, which binds plasma fibrinogen as well as that secreted from activated platelet granules.

Q

What disorders can affect fibrogen?

A

The function and quality of plasma fibrinogen can be altered by both inherited and acquired disorders. Some common causes of decreased fibrinogen concentration are increased consumption during localized or disseminated intravascular coagulation, severe hepatic dysfunction, and hemodilution. Low plasma fibrinogen concentration is associated with an increased risk of bleeding, due to impaired primary or secondary hemostasis. Fibrinogen is a positive acute-phase protein that increases in response to inflammatory processes.

Q
  1. A reason for the variability with stereotypical behavior reduction was that the methods of distribution of the enrichment devices may have led to stress and fear. According to this assumption which device was the least stressful and why?
    a. Puzzle Balls were easy to manipulate
    b. Shakers were not very novel
    c. Supertubes were given without opening the cage door.
A

c. This explained why supertubes were the only device in which no significant increase in stereotypy was observed.

41
Q

Describe how the study illustrated that alopecia of nonhuman primates cannot be attributed solely to hair plucking.

A

Only 53.9% of animals in the alopecic group were seen to hair pluck. The assumption that a behavioral etiology is responsible for all cases of alopecia would have overestimated the actual number of animals that hair plucked and let to inappropriate diagnosis for almost half of alopecic animals. In addition, hair plucking may not be the primary underlying cause of hair loss in these animals, because both hair plucking and alopecia are multifactorial diseases. Also, 13% of control animals were observed to hair pluck, suggesting that hair plucking that does not lead to clinical alopecia may be more prevalent than previously thought.

42
Q

T/F – The positive dermatophyte cultures in the present study represented an underlying fungal etiology for two alopecic animals.

A

False – Four animals cultured positive for dermatophytes. The medium of one alopecic animal grew Aspergillus spp and another Penicillium spp, while the medium of one control animal grew Cladosporium spp and another Penicillium spp. All isolates were the 3 most common fungal isolates in a survey of dermatophyte cultures performed on domestic and laboratory animals. In addition, other than alopecia, few dermatologic lesions consistent with dermatophyte infections (such as scaling, crusts, and erythema) were noted.

43
Q

What was the only serum biochemistry value that was significantly different in the alopecic group compared to the control group?

a. Increased serum creatinine
b. Decreased serum creatinine
c. Increased creatine kinase
d. Decreased creatine kinase

A

b. Decreased serum creatinine (practical utility unknown)

44
Q

Which of the following situations will result in a significant loss in amniotic fluid in a sheep fetus?

a. Fetal surgical catheterization with all membranes closed tightly around the catheters.
b. Fetal surgical catheterization with an incomplete closure of the amnion.
c. Fetal surgical catheterization with an incomplete closure of both the amnion and chorion.
d. b or c

A

D

45
