Many systems of the body change during the transition from a resting state to submaximal aerobic exercise. Describe what happens to heart rate, total peripheral resistance, ventilation and muscle oxygen consumption, comparing resting values to those measured during submaximal exercise (1/4mark each). Include in your answer the relationship between these variables (1 mark).

Discuss Jeff’s addiction to smoking using what you know about dependence and
withdrawal and what you know about smoking addiction. You should include in your
discussion pharmacological aspects of smoking and addiction. (5 marks)
2. Compare and contrast the different methods that Jeff has used to quit smoking to what
the doctor has prescribed now.
Jeff is a 42-year-old man, married with two children. He started smoking at 15 years of age
and now smokes around 25 cigarettes a day. His wife and children for some time have been
asking him to quit, and he will admit that it is very expensive. It is also difficult to smoke
during work as around the building where he works smoking is banned so he needs to walk for
five minutes to find a spot where he can smoke – he worries that people are noting his absence
and his job is at risk. He has tried a number of times to stop cold-turkey and chewing nicotine
gum, once even lasting three months, but he always seems to start back up again if he gets
stressed.
Last week while playing football in the park with his daughter he felt very short of breath. On
his family’s assistance, he went to the doctor and was given an ultimatum, he needs to stop
smoking or there will be further health consequences. The doctor wrote him a script for
varenicline.
The addiction lab at the Neuroscience Institute of Victoria is working with a small start-up
pharmaceutical company to try and formulate a new drug for the market in the treatment of
long-term alcohol addiction. In the lab pharmacological studies in vodka-addicted rats have
shown that administration of the drug in quite high doses has been successful in reducing
alcohol intake. In vitro studies suggest that the drug interacts with both the dopamine and
GABA receptors in the brain.
1. What are the considerations that need to be made when making a drug that needs to
cross the blood-brain barrier?
2. Discuss how you think this drug is reducing alcohol intake? In your answer you should
consider the pharmacology of both neurotransmitters.
3. Compare this potential drug to other drugs involved in treating alcohol addiction.
