Question

Meningitis is an inflammation of the membranes that cover the brain and spinal cord. Diagnosis involves making a "spinal tap" (lumbar puncture) and analyzing a sample of cerebrospinal fluid for signs of infection. Why analyze this fluid and not blood? In newborns and premature babies, the blood -brain barrier is not fully developed. Explain why this might be reason enough to pay careful attention to their diet. In PET scans, red areas are brain regions that are 'active, while blue, yellow, and green areas are least active. Figure 13.28 shows PET scans of normal brain activity (left) and of the brain of a person while using cocaine (right). The frontal lobes of the brain hemispheres are toward the top of the scans. Their neurons play major roles in reasoning and other intellectual functions. Looking at these scan images, how do you suppose cocaine may affect mental functioning?

Explanation / Answer

1) Lumbar puncture is used to diagnose meningitis and helpful in diagnosing some other brain and spinal cord disease.meningitis is an affect of meninges the structure that surrounds the brain and spinal cord .It used to help diagnose some conditions of brain and spinal cord by cerebrospinal fluid collecting due to emerge procedure like meninges to diagnose it quickly is done.

Because blood test is not done due to people with meningitis the CSF often shows a low sugar level along with an increased white blood cell count and increase protein.

3) Cocaine is a stimulant directly affects brain function and long term addiction leads to extensive physiological and psychological problems.cocaine is a powerfully additive stimulant that directly affects the brain .Long term effects of Cocaine use include addiction irritability and mood disturbances and paranoia and auditory hallucinations.

2)To predict drug specific reaction and adverse reaction to drugs .Small lipid insoluble due to little synthesized at blood .Any ALA or DHA added to diet must be protected from oxidation in both for food itself and in the tissue into which it is Incorporated
