Without this, a child would suffer brain damage, muscle and nerve damage and die due to bilirubin toxicity.

5. What is the significance of the cross in medicine?

Ans: The history of the cross in medicine seems to have originated with Christian monks running free hospitals. These monks either wore crosses hanging as pendants, or robes with crosses painted over them, or used the cross as a source of relief for the sick. In 1859, Swiss businessman Henry Dunant founded the International Committee for Relief to the Wounded to medically aid the war-wounded regardless of nationality. For its logo, Dunant reversed the Swiss national flag, a white cross on a red background. But the symbol gave a spiritual cloak to the organisation’s selfless service and became so identified with its work that people referred to it by the name of the emblem.

6. What is the procedure to differentiate between blood groups?

Ans: The blood group is found out by adding two chemicals Anti Sera A and Anti Sera B to the sample. If the sample gets agglutinated by Anti Sera A, and not by Anti Sera B, the sample is A. If it gets agglutinated by B, but not by A, the sample is B. If it gets agglutinated by both, the sample is AB, and if by neither, the sample is O. The Rh factor is found out by adding another chemical, Anti Sera D to the sample. If the sample gets agglutinated, it has a positive Rh factor, else it has a negative Rh factor.
