Q

what does Intra-uterine device do?

A
  • Prevents endometrial thickening
25
With IUD you can get dysmenorrhoea (period pain). TREU RO FALSE?
TRUE
26
what does copper IUD do?
- Releases copper which prevents fertilization
27
Give an example drug dor emergency contracetpive and what it does?
- Levonorgestrol- high single dose, | - It blocks LH surge which prevents ovulationa nd implantation
28
Ulipristal (SPRM) is an emergency contraception and is useful 120hr after intercourse. TREU RO FALSE?
TRUE
29
Emergency contraception not effective after implantation. TRUE OR FALSE?
TRUE
30
what is mifepristone and what is it used for?
- Progesterone receptor antagonist | - Used for abortion
31
how does mifepristone work?
- Blocks progesterone receptor causing decay of decidua and embroy dies and detaches
32
mifepristone can be used with misprostol to induce contractions. TRUE OR FALSE?
TRUE
33
what are the ADRs for mifepristone?
- Causes serious bleeding
34
estrogen receptor agonist can be natural and synthentic and can be used for hormonal replacement therapy. TRUE OR FALSE?
TRUE
35
What does SERMs stand for?
- Specific estrogen receptor modulators
36
SERMs are medicines with selectivity for different tissues. TRUE OR FALSE?
TRUE
37
what is Raloxifene a agonist and antagoist for?
- Agonist in bone | - Antagonist in breast and uterus
38
what is Tamoxifen a agonist and antagoist for?
- Agonist in bone and uterus | - Antagonist in breast
39
when does menopause occur?
- When all follicles have been depleted
40
in menopause there is decreased estrogen and inhibin which leads to less FSH and LH. true or false?
true
41
what does estrogen synthesis depend on?
- Aromatase synthesis in adipose tissue | - Hence less estrogen which is previous source of granulosa cells in follicles
42
what are symtpoms of menopause?
- Hot flushes | - Vaginal dryness
43
what is involved in hormonal replacement therapy?
- Progestin and estrogen to prevent risk of cancer
44
what are the ARDs for HRT?
- Stroke, breast cancer, increased risk of coronary heart disease
45
there are reduced hip fractures from osteoproisis with HRT. TREU RO FALSE?
TRUE
46
Tamoxifen is an ER antagonist that inhibits estrogen dependent growth of breast cancer. TRUE OR FALSE?
TRUE
47
Why is tamoxifen use limited to 5 years?
- Because of tis increased risk of endometrium cancer
48
How do SERMs work?
- Tissue specific pattern of estrogen receptors - Tissue speciif cpattern of co-regulator expression - Effects on ER stability and degradation
49
what are the two Tissue specific pattern of estrogen receptors identified?
- ERa | - ERb
50
SERMs have different affinties for ERa and ERb homodimers and ERa and ERb heterodimers. TREU OR FALSE?
TRUE
51
The pattern of genes activated by ER activation is regulated by the expression of what?
- Co-regulatory proteins
52
Co-regulatory repertoire varies from tissue to tissue (genes activated in bone are different from those in breast. TRUE OR FLASE?
TRUE
53
Co-regulator recruitment may be ligand dependent, thus a ligand may recruit co-activators specific to one tissue but co-repressors specific to another. TRUE OR FALSE?
TRUE
54
Some ER antangonists have been shown to increases the rate of ER degradation. TREU RO FALSE?
TRUE
55
Describe how SERMs achieve selectivity?
- Differential SERMs effects on estrogen receptor dimers (either ERa ERb homodimer or heterodimer - Co-activator complex alters gene expression and response to SERM - Differential effects on ER degradation (depedent on receptor subtype and co-activator complex)
56
what are the good and bad effects of Tamoxifen?
- Good: - Reduces breast cancer risk - Lowers LDL cholesterol - strengthens bones Bad: - Increases uterine cancer risk - Inreases blood clot risk
57
what are the good and bad effects of Raloxifene a newer SERM?
- Good: - Strengthens bones - Lowers LDL cholesterol - Reduces risk for invasive breast cancer - Fewer uterine cancers than tamoxifen - Fewer blood clots than tamoxifen Bad: - Blood clots, hot flushes, teratogenic
58
The antagonistic activity of Raloxifene in breast and endometrium does not increase risk of endometrial cancer. TRUE RO FALSE?
TRUE
59
The agonist activity of Raloxifene in bone decreases bone resorption which is used to delay and prevent progression of osteoporosis in post menausal women. TREU OR FALSE?
TRUE
