National Bank Limited Probationary Officer - 2015

Read the passage and answer the questions given below.
Many folk cures which have been around for centuries may be more therapeutic than previously suspected. A case in point is that of penicillin. Alexander Fleming did not just randomly choose cheese molds to study when he discovered this very important bacteria-killing substance. Moldy cheese was frequently given to patients as a remedy for illness at one time. Fleming just isolated what about the cheese which cures the patient.
In parts of South America, a powder obtained from grinding sugar cane is used for healing infections in wounds and ulcers. This usage may data back to pre-Colombian times. Experiments carried out on several hundreds patients indicates that ordinary sugar in high concentrations is lethal to bacteria. Its suction effect eliminates death cells, and it generate3s a glasslike layer which protects wounds and ensures healing.
Another example of folk medicine which scientists are investigating is that of Arab fishermen who rub their wounds with a venomous catfish to quicken healing. This catfish excretes a gel-like slime which scientists have found to contain antibiotics, a coagulant that help close injured blood vessels, anti-inflammatory agents, and a chemical that directs production of a glue-like material that aids heading.
It is hoped that by documenting these folk remedies and experimenting to see if results are indeed beneficial, an analysis of the substance can be made, and synthetic substance can be developed for human consumption.
