1 GCSE-HIST-TWE-0145

In which year did Alexander Fleming notice a mould killing bacteria on a culture dish at St Mary's Hospital, London? (year)

1928

提示The year before the Wall Street Crash.

为什么He had left the dish out while on holiday. He named the substance penicillin and wrote up what he had seen, but he could not purify it and moved on to other work.

2 GCSE-HIST-TWE-0146

Which two scientists at Oxford led the work that turned penicillin into a usable drug from 1939?

Howard Florey and Ernst Chain

提示They shared the 1945 Nobel Prize with Fleming.

为什么Their team purified enough to test it on a patient, a policeman named Albert Alexander, in 1941. He began to recover, but the supply ran out and he died.

3 GCSE-HIST-TWE-0147

Which country's government and drug companies took on the mass production of penicillin during the Second World War?

The United States

提示British factories were busy with war work and under threat of bombing.

为什么Florey travelled there in 1941 to ask for help. By D-Day in June 1944 there was enough to treat Allied casualties. It is an example of war and government speeding up a medical development.

4 GCSE-HIST-TWE-0148

Why are some bacterial infections becoming harder to treat with antibiotics?

The bacteria have evolved resistance to them

提示Heavy use gives the toughest survivors the chance to multiply.

为什么Fleming himself warned of this in 1945. Strains such as MRSA no longer respond to some common antibiotics.

5 GCSE-HIST-TWE-0149

Which drug, given to pregnant women for morning sickness around 1960, caused serious harm to thousands of babies and led to stricter testing of new medicines?

Thalidomide

提示The disaster became public in 1961.

为什么It was withdrawn in 1961. Britain then set up a committee to check the safety of new drugs, and testing rules were tightened in many countries. The growth of the drug industry brought new risks as well as new cures.

6 GCSE-HIST-TWE-0150

Which surgeon pioneered plastic surgery on wounded British soldiers during the First World War, at a hospital in Sidcup?

Harold Gillies

提示A New Zealander; a younger cousin carried the work on in the next war.

为什么Shells and bullets caused terrible injuries to faces. Gillies developed new ways of moving skin from one part of the body to another, and kept careful records so that others could learn from them.

7 GCSE-HIST-TWE-0151

Which surgeon treated badly burned airmen at East Grinstead in the Second World War, where his patients formed the 'Guinea Pig Club'?

Archibald McIndoe

提示A cousin of the plastic surgery pioneer of the earlier war.

为什么He improved the treatment of burns and paid attention to how his patients would cope with life afterwards, encouraging them to go out into the town and be seen.

8 GCSE-HIST-TWE-0152

What did Karl Landsteiner discover in 1901 that made blood transfusion far safer?

Blood groups

提示It explained why some transfusions killed the patient.

为什么Before this, transfusions often killed the patient, because blood of the wrong type makes the cells clump together. Matching donor to patient solved one problem; storing blood was the next.

9 GCSE-HIST-TWE-0153

What problem was solved during the First World War by adding sodium citrate to donated blood?

It stopped the blood clotting, so it could be stored

提示Outside the body, it soon sets solid.

为什么Until then the donor had to be present beside the patient. Stored blood could be taken to where the wounded were, and the first blood depots were set up for the army in France in 1917.

10 GCSE-HIST-TWE-0154

Who discovered X-rays in 1895?

Wilhelm Röntgen

提示A German physicist.

为什么Their use in medicine was seen almost at once. In the First World War, Marie Curie developed mobile X-ray units that served hospitals close to the battlefield.

11 GCSE-HIST-TWE-0155

In which year did Christiaan Barnard carry out the first human heart transplant? (year)

1967

提示Two years before the first Moon landing.

为什么The operation took place in Cape Town, South Africa. The patient lived for eighteen days. The great obstacle was rejection of the new organ by the body, which better drugs later helped to control.
