  1. transcription of casein mRNA
  2. stimulate synthesis fo alpha-lactalbumin
  3. increase lipoprotein synthesis
139
Q

alpha-lactalbumin

syn. by PRL

regulatory protein of lactose synthetase

140
Q

141
Q

colostrum
compare to mature milk

2. less of what

A

first few days of nursing
low volume, high nutritional content

2. less: carbs, lipids, K

142
Q

breast milk

A

glucose
also: amino acids, minerals, lipids (lipids rise through nursing episode)
nursing increases blood flow to breast: increase CO and vasodilation
Maternal diet variation: does NOT cause variation in milk components

143

Q

def. and causes of chronic pelvic pain

A

DAILY pain (can be worse around menses)

5. adhesions
often hard to pinpoint so GI, GU and musculoskeletal causes can be confused with it

145
Q

146
Q

Chronic pelvic pain workup

A

Hx, physical, US

last resort: laparoscopy (may detect endometriosis, adhesions)

147
Q

Chronic pelvic pain Tx

A

NEVER start narcotics for chronic pain: can get addicted
AVOID: laparotomy (leads to adhesions that cause pain and more Sx cycle)
Requires a TEAM: Gyn, Uro, PT, pain management center, Psych
no known cause: sympathy, counsel. laparoscopy can be therapeutic: women get better if told pelvis is ok
non-narcotic pain meds for NM pain
