How occurs stroke?

Stroke is a condition characterised as lacking of blood flow in brain cell. blocking of blood flow in brain cell when causes brain cell death of any portion of brain is called stroke. 

 Sometimes blood flow may blocked in brain for a little time left no cell damage is termed as TIA. TIA means transient Ischemic Attack. It may also characterised as mild stroke.

 Ischemic means lacking of Oxygen. To servive every cell required oxygen to perform metabolism. Blood perform gaseous exchange into cell. It carries oxygen into cell and pick up carbon dioxide from cell. Any restriction of blood flow toward Brain cell causes brain cell damage and cell death due to lackings of oxygen supply.

 There have certain cause that triggered stroke to happen. These are is as bellow,

 Atherosclerosis forms blood clot inside blood vessel that can block blood flow. 

 High blood pressure suddenly can cause blocking. 

 Diabetes melitus can causes blood clotting.

 Deep vein thrombosis may cause stroke, heart attack or pulmonary embolism.

 How to prevent stroke? 

 Stroke is preventable. avoiding red meat and fat is the primary action to prevent stroke. Though animals meat is the major source of protein and we required protein we need meat for a certain requirement such as omega 3 fatty acid. We need to prefer selective protein that contains less bad fat. Fish and fish oil should be better choice. Avis meat be a good choice. Egg can also provide protein with good nutrition. Research shows that daily physical exercise significantly reduces stroke incident.

Effect of Vitamin E for healthy hair

 Vitamin E have an antioxidant property. It is also a solvant of fat. For that reason it have some skin beneficial effect. 

Vitamin E improves blood flow in scalp. That provides nutrient to scalp, skin and hair. Reduces the damage of scalp cell. As a result reduces the damage of scalp hair follicles.

It ensures healthy hair. 

We know that agging problem is associated with free radical associated cell damage. Vitamin E restrict free radical associated damage of cell. 

It reduces the oxidative stress on scalp that is responsible to hair loss.  Hence, it reduces hair loss. 

How develops scars

 Scars is an area on skin formed by fibrous tissue.  Scars forming is a process of repairing of damage skin. 

For a certain cause scars may develop.These are injury,  burn, surgery, cutting of skin, any damage on skin.  It is a normal healing process of skin. It replaces the dead skin.  

Scars tissue and skin tissue have some basic difference. Scars tissue is not similar with natural skin or muscular tissue. Scar tissue is can not restrict ultraviolet radiation sufficiently like skin tissue. No hair follicles grows on scar tissue. Hence, sun burn is not safe with scar tissue. Function of scar tissue is also different. Due to myocardial infarction scar tissue develops in heart to repair damaged heart.  For that reason normal function of heart reduces and increases the chance of heart failure. 

There have several types of scar tissue in skin. Flat scars, raised scars. 

Hypertrophic scars raised from the skin. Keloid is the very severe form of scars. It is abnormallly big and raised and forms tumours. But tumours are benign and non cancerous growth. Mostly in dark skin people keloid scars are found. 

Prevention of cancer

 Cancer is a condition of abnormal cell division. According to research held by Stanford University Genetic mutation is the main cause of cancer development.

Cancer is one of the death causing disease worldwide. Incidence of cancer occurance increasing day by day. It is our challenge as healthcare professionals and researcher now a day to concern about cancer. 

If there any way to prevent cancer.  Increasing population different types of pollution, infections triggers cancer incidence. Mortality rate is very high about late diagnosed cancer. When cancer became metastasis the condition became uncontrollable. 

The common cancer in world is Breast cancer, Cervical cancer,  limphoma
