suborder for hamsters?

Myomorpha

8

anatomical characteristics

large cheek pouches, thick bodies, short tails, excess loose skin, only incisiors erupt continuously

9

Native environment and behavior

arid, temperate regions, live deep in tunnels where cooler and more humid. Diurnal activity in wild

10

activity in laboratory environment

nocturnal

11

origin of Syrian hamster

originated from one litter captured in Syria in 1930

12

Carcinogenesis model

1) cheek pouch carcinogenesis oral tumor formation
2) pancreatic ductal adenocarcinoma: nitrosamine
3) SV40: oncogenic virus
4) Human adenovirus: potential cancer therapeutic
5) exogenous estrogen to males leads to renal tumors

13

Metabolic disease models

1) cholesterol cholelithiasis: excess dietary cholesterol or sucrose-rich diet
2) diabetes mellitus: STZ or alloxan
3) Atherosclerosis through dietary manipulation

14

Cardiovascular models

1) cardiomyopathy (DCM and HCM) sarcoglycan gene (dystrophin complex)

15

Infectious disease models

1) Leishmania
2) Hantavirus
3) SARS
4) prions

18

Puberty

M 6-8w
F 8-12w

19

characteristics of the cheek pouch

extensively microvascular
immune privilaged

20

unique characteristics of respiratory system

develop centrilobular emphysema when exposed to intratracheal porcine pancreatic elastase- model for COPD

21

sexual dimorphism of hardarian gland

females secreate 10^3 more porforin

22

diet for hamsters

standard rodent diets

23

T/F Placement of the food on the floor is not allowed for Hamsters.

False: IT IS allowed

24

fluid requirements

8.5ml/100g (Low when compared to other species, linked to natural adaptations for water conservation)

25

Name two unique pharmacological responses seen in hamsters

more sensitive to metabolic effects of corticosteroids
less senstive to effects of morphine

26

length of estrous cycle

4 days

27

best time to mate hamsters

third day after postovulatory discharge, copious creamy white opaque viscous discharge

28

pregnancy determination

abdominal distention around 10 days post breeding, absence of postovulatory discharge 5-9 days post breeding (normal estrous cycles)

29

when does the estrous cycle resume following parturition?

1-8 days

30

hamster weighing 60g or less needs how much space

10in^2
