Introduction: A viral test is done to find infection causing viruses .Viruses grows only in living cells. Viruses causes disease by destroying or damaging the cells they infect , damaging the body’s immune system Changing the genetic material (DNA) of the cells they infect or causing inflammation that can damage an organ . Viruses cause many types of diseases, such as human immunodeficiency virus (HIV), cold sores, chicken pox, measles, flu and some types of cancer Project nuclear medicine: Nuclear medicine is the medicine made of nutrients mixed together and generated immune cells are mixed together and these medicines is generated in body to make new immune fight against virus. When energy is released, a high amount of transformation occurs and nucleus is transformed in nuclear proteins. New characteristics of a particular organism grow faster and lead to proper development of organism. DNA backward rolling leads to the deforming the cells and lead to formation of two organism again. Effect of DNA background rolling: 1. New characteristic does not grow fast. 2. Deformation of new organism into old two organisms Introduction of nuclear medicine: Nuclear medicine is made up of the glucose fats proteins and vitamins, huge amount of immune cells with iron oxide. The glucose fats breakdown and release energy, proteins and vitamins build up and repair damaged tissue. Immune cells released in body build up and divide the other immune cells and fight against virus and its infection. Nuclear medicine affect the virus by increasing and repairing immunity of body by increasing energy in body and by building up the immune cells by proteins. An animal who is affected by the virus should take two times a nuclear medicine in an hour, as because immune system takes large time to repair. 1. Nuclear medicine increases the immunity of the body and also some amount of temperature. 2. Nuclear medicine increases the energy of the body and build up the body muscles. Taking large amount of nuclear medicine can lead to increase the large amount of temperature and can even lead to dehydration. The nuclear medicines increases the immunity, energy in the body and even increases the temperature of the body and even build up the immune system strong and even body capacity to fight against the infection.
