1. Is gene therapy really a realistic approach to curing diseases? Discuss a few recent trials on gene therapy to support your opinion.
Yes, gene therapy is an alternative medicine to cure diseases especially inherited diseases like muscular dystrophy, cystic fibrosis, cancer as well as heart disease. Gene therapy can give a promising result for a rare inherited disease. One of the examples is the disease that causes progressive blindness or choroideremia. This disease affected 1 in 50 000 people around the world in which currently doesn’t have any cure. However, after underwent therapy, patients show improvement in their vision as the particular gene (CHM gene- Rab escort protein 1) was successfully delivered to their retina and thus produce protein that they were lacking of. This gene is responsible to stop the cells of the retina from dying ...view middle of the document...
The treatment gives no adverse effect. Their movement and quality of life have been improved. This indicated that the dopamine has successfully produced at an area where it was not before. Although this therapy does not cure this disease 100 % but it reduce the complication and makes patients life better that before they were being treated.
3. Is it better to have a dengue vaccine or to improve public awareness of cleanliness (to prevent mosquitoes breeding)?
From my point of view, improving public awareness of cleanliness is better than the others. Everything begins with our own effort as a public whether or not to keep our environment condition clean at the first place. If we live in a clean environment, the possibility of breeding mosquitoes is low. So, the campaign has to be launched to help in increase awareness of public on the danger of dengue. This campaign is function to educate people about preventive measures to make their community free from dengue. People have to take active action to prevent dengue.
Schoolchildren are the main target as they must be educated well while they are young. This later will become their habit to ensure their environment is clean enough.
There a few simple steps to be taken to prevent mosquitoes breeding instead of investing too much on creating complicated vaccines. Firstly, all water and air coolers should be cleaned once a week and dried out before reuse. Secondly, water tanks in house or office should be kept covered and if possible air tight. Thirdly, temporary water container used to store water should be drained out and kept covered after refilling. Next, collection of waste water should not be allowed inside or outside the building. Lastly, the unused or broken bottles, cups, pots and tyres which can hold water should not left open.
After all, prevention is better than cure. When there are no vaccines to cure dengue yet, prevention is the most important step to be taken first.
