25
CYP inhibitors

26
induction of changes in the genetic materials of any animal of any age
mutagenesis
27
induction of malignant characteristics of cells
carcinogenesis
28
standard in vitro test for mutagenicity
Ames test
29
in vivo mutagenicity test carried out in mice | male animals exposed to test substance before mating
dominant lethal test
30
high mutagenicity and carcinogenicity drugs
``` coal tar aflatoxin nitrosamines urethrane vinyl chloride polycyclic aromatic hydrocarbons in tobacco smoke (benzo alpha pyrene) ```
31
AcH is synthesized from
acetyl coA and choline by choline acetyltransferase (ChAT)
32
choline transport is inhibited by | Ach synthesis
hemocholinium
33
Ach is actively transported into vesicles for storage by
VAT | vesicle associated transporter
34
Ach storage is inhibited by
vesamicol
35
this chemical triggers release of Ach which interacts with SNARE proteins (VAMPs and SNAPs)
calcium
36
this poison will prevent release of Ach
botulinum toxin - alter synaptobrevins
37
Ach degraded to
acetate and choline
38
cholinoreceptors in nerve endings
M1
39
cholinoreceptors in | heart muscle, nerve endings
M2
40
effector cells: smooth muscle, glands, endothelium
M3
41
loop diuretics
furosemide bumetanide torsemide ethacrynic acid
42
MOA of loop diuretics
Inhibit Na/K/2Cl transporter in TA: | inc Ca excretion
