-
homeostasis
-
food in
-
carbohydrate
- glucose into blood
- process via gut!
- only carbohydrates put blood sugar level up
-
glucose removal from blood
- metabolism (reactions)
- vigorour exercise
-
control of glucose level
- pancreas
-
HORMONE
-
INSULIN
- controls sugar level in blood
- a regulatory substance produced in an organism
and transported in tissue fluids such as blood or
sap to stimulate specific cells or tissues into action.
-
Diabetes (type1)
-
pancreas
-
not enough insulin produced
-
blood sugar level too high
- DEATH!
-
control
-
dietary control
-
avoid SIMPLE carbohydrate rich foods
- simple carbs = rapid glucose rise
-
exercise after eating
- use up excess glucose
-
Inject Insulin
-
mealtimes
- especially if high in carbohydrates
- liver remove glucose
-
eat sensibly
- blood sugar can drop
- dangerous!
-
amount
- person dependent
- amount of exercise
- diet
- inject 2-4 times a day
-
can not take a pill
- enzyme in stomach destroy it
-
glucose check
- glucose monitoring device
-
prick finger
- drop of blood to check
- lot of sugar in urine
-
side effects
- blindness
-
gangrene
- localized death and decomposition of body tissue,
resulting from obstructed circulation or bacterial infection.
-
pancreas transplant
-
organ can be rejected
-
immunosuppressive drugs
- costly
- may have serious side effects
-
transplant insulin producing cells
- only experimental as yet
- problems with rejection
-
other theoretical
- stem cell research
- artificial pancrease
-
health problem
-
overweight
- diabetes on the rise
-
discovery
-
pancrease removal in dog
- diabetic
-
Frederick Banting & Charles Best
- isolated insulin (1920)
-
tied string round pancrease
- insulin production bits remained
-
removed pancrease
-
extracted insulin
- injected insulin into diabatic dog
- watched blood sugar level drop
- isolated substance
- nobel prize 1923
-
at first
- insulin from pigs & cows
- boil syringies
-
genetic engineerins
- 1980s
-
human insulin made
- slow acting
- intermediate
- fast acting
-
syringes
- disposable
- sterile
- needle free devices available
