Q

What is fatty liver syndrome

“DILI”

A
  1. liver uses fatty acids as fuels
  2. alcohol is used instead of lipids
  3. fat builds up in the liver cells until they burst and release lipids into the blood
  4. bad for cardiovascular system

Q

what are the Day 2 withdrawal symptoms of alcohol and barbituates

A
  1. delirium tremens, gross tremors and convulsions
  2. can use benzodiazepines as anticonvulsants
  3. breathing stops during the convulsions and can cause death

21
Q

Cardio vascular effect of chronic use

A
  1. myocardial infarction- heart attack, blood supply to heart becomes occluded
  2. angia pectoris- moderately insufficient blood supply to the heart
  3. cardiomyopathy- heart muscle become less efficient

all can be due to fatty liver syndrome

22
Q

fetal alcohol syndrome and fetal alcohol effects

A

There are birth defects associated with drinking during pregnancy
1. cleft palate
2. heart disease
3. minimal brain dysfunction

23
Q

peripherally effects

A

causes dilation of blood vessels so it seems like you are warmer but heat is really leaving the core of you body where you need it

24
Q

centrally effects

A

another way of thinking about alcohol effects by considering what areas were effected

25
Q

motor effects

A

are know to be caused by effects in the cerebellum and basal ganglia

26
Q

hypothalamic effects

A

probably produce a decrease in feeding and an increase in water intake and also a decrease in sexual functioning

27
Q

Limbic system effects

A

blackout, loss of memory, Korsakoff’s disease, increase in emotionally, state dependent memory, long term cortical depression that is not well understood

28
Q

hormonal effects for males

A
  1. heavy use causes a decrease in sperm count - 5 times in the enzyme that degrades testosterone
  2. the book says not to worry because it takes a lot of drinking to get this effect
  3. male infertility is a major problem in reproductive medicine - a small decrease in sperm count can cause problems
29
Q

synergies for alcohol and benzodiazipines and barbituates

A

huge decrease in heart rate, breathing, and body temp increase in neuronal death

30
Q

synergies for alcohol and smoking

A

astronomical increase in oral cancer rates

31
Q

synergies for alcohol and pesticides and food additives

A

increase the toxicity of both

32
Q

what is Korsakoffs disease

A

damage to the hippocampus, causes holes, takes about 30-40 years of drinking to cause damage

33
Q

where was the first place where there were attempts to control alcohol

A

England

34
Q

describe how alcohol is made

A

yeast eats sugar and burps COs and pees ethynol and then dies in its pee.

35
Q

what is the max that fermentation can get to before you have to distil to get higher concentrations

A

15% or 30 proof

36
Q

what is Microsomal Ethanol Oxidizing system (MEOS)

A

It is an alternate pathway to ethanol metabolization - MEOS activity increases after chronic alcohol consumption.

37
Q

what is fatty liver syndrome

A

when alcohol is used instead of lipids the liver usually uses for fuel and that fat (lipids) start to uild up and they start to burst and get released into the blood.

38
Q

Delirium Tremens

A

gross tremors (big movements) and conclusions

39
Q

Are breathalyzers accurate

A

yes

40
Q

Myocardial Infarction

A

caused by chronic use of alcohol (heart attack, blood supply to heart is blocked).

41
Q

Angina Pectoris

A

caused by chronic use of alcohol (insufficient blood supply to heart).

42
Q

Cardiomyopathy

A

caused by chronic use of alcohol (heart muscle becomes less efficient)

43
Q

what is the current rat of fetal alcohol syndrome babies

A

1% of all births

44
Q

how quickly can a fetus metabolize alcohol

A

28mh/12hr

45
Q

how many milligrams of alcohol can an adult metabolize per hour?

A

700mg/hr

46
Q

how does alcohol peripherally affect you?

A

creates dilation of blood vessels so it seems like you are warmer but the heat is leaving the core of your body.

47
Q

what two items in your body does alchol affect to target your motor funciton

A

cerebellum ad basal ganglia

48
Q

how does alcohol create hypothalamic effects

A

decreases hunger and increases thirst, and decreases sexual functioning (increases desire but inhibits preformance)

49
Q

how does alcohol affect your limbic system?

A

in your hippocampus (blackouts and loss of memory), Korsakoff’s disease (anterograde amnesisa) and emotionally (cortical depression)

50
Q

what shows the best images of white matter

A

diffusion tensor imaging

51
Q

what are the three synergies we talked about in class with alchol.

A

alcohol + benzos
alcohol + smoking
alcohol + pesticides and food additives
