It contains lymphocytes and phagocytes and a large number of erythrocytes are present, Lymph nodes trap the antigens present in the lymph or tissue fluid, Caused by HIV (Human Immuno Deficiency Virus), It is a retrovirus with RNA as its genome, The virus produces viral DNA in the host by the enzyme reverse transcriptase, The viral DNA gets incorporated into the host genome and multiple copies of the virus are produced, The virus attacks helper T-cells, where it replicates and multiplies, resulting in the marked decrease in the number of T lymphocytes, The infected person becomes immunodeficient after the virus attacks T- helper cells, AIDS patient become prone to various infections like mycobacterium, toxoplasma, fungal and other viral infections, ELISA (Enzyme-Linked Immuno-Sorbent Assay) is a widely used diagnostic test for AIDS, AIDS may be transmitted by sexual intercourse, contaminated blood transfusion, using an infected syringe or from mother to foetus through the placenta, NACO (National AIDS Control Organisation) works for the awareness and prevention of AIDS by educating people, Cancer is caused due to uncontrolled cell division leading to the formation of tumours, There is a breakdown of regulatory mechanism in oncogenic transformation of normal cells, Cancerous cells lack contact inhibition property, which inhibits further growth of cell on contact with other cells, Cancer is caused due to DNA damage or genetic mutation resulting in the faulty regulation of the cell division, Cancer can also be caused due to the activation of proto-oncogenes present in normals cells under certain condition, Cancer can be diagnosed by using a CT scan (computed tomography), MRI (magnetic resonance imaging), X-ray, PET scan (positron emission tomography) or by histopathological studies of tissue and blood, Cancer can also be diagnosed using molecular biology techniques to identify inherited susceptible genes for certain cancers, Antibodies against cancer antigens can also be used for diagnostic purpose, Cancer can be treated by surgery, transplantation, immunotherapy, radiation therapy, -interferon act as biological response modifier, which activates the immune system to destroy tumour, Opioids, cannabinoids and coca alkaloids are commonly abused drugs, There are opioid receptors present in our CNS and GI tract, where opioid drugs bind, Diacetylmorphine is commonly known as heroin or smack.

The suspected pathogen should be invariably present in the animals suffering from the disease and should not be found in healthy individuals. These diseases remain confined to the person who develops them and do not spread to others. Alcohol decreases the activity of CNS thereby, reducing anxiety, tensions and inhibitions.
