A stroke, previously known medically as cerebrovascular accident (CVA) --- The stroke also known as cerebral apoplexy ,it can be classified into two major categories: ischemic and hemorrhagic. The ischemic stroke is also called as cerebral infarction, including cerebral thrombosis and cerebral embolism etc. The real causes of ischemic stroke are high viscosity bloodblood viscosity and hyperlipemia, so lowering blood viscosity and blood lipids is the key point to prevent and treat stoke. Verified by clinical tests, irradiation to blood by the semiconductor laser treatment instrument can greatly improve the patients’ cerebral blood flow and cerebral oxygen supply.

For the patients with prodrome of stroke, the semiconductor laser treatment instrument can effect as a active prevention method;- play a positive effect of prevention.  For the patients suffered from stroke, it can improve the oxygen carrying capacity of blood and minimize the hurt to cerebral tissues by stoke.-damage of brain tissue. After long-term use of the product, the sequelas of stoke can be improved gradually and the cerebral functions can be recovered step by step. During clinical application of the product, a lot of patients restored their language and movement abilities, even a patient in deep coma (plant man) for 134 days was awaken.

PBM for stroke                                                                                                                                                                                                                 

Perhaps the most well-investigated application of PBM to the brain, lies in its possible use as a treatment for acute stroke [57]. Animal models such as rats and rabbits, were first used as laboratory models, and these animals had experimental strokes induced by a variety of methods and were then treated with light (usually 810 nm laser) within 24 h of stroke onset [58]. In these studies intervention by tLLLT within 24 h had meaningful beneficial effects. For the rat models, stroke was induced by middle cerebral artery occlusion (MCAO) via an insertion of a filament into the carotid artery or via craniotomy [59], [60]. Stroke induction in the “rabbit small clot embolic model” (RSCEM) was by injection of a preparation of small blood clots (made from blood taken from a second donor rabbit) into a catheter placed in the right internal carotid artery [61]. These studies and the treatments and results are listed in Table 1.

CLINICAL RESULT                                                                                                                                                                                                              

After about 30 mins irradiation treatment, blood-red cells will be activated, become single, active, healthy and normal.

After about 30 days of treatment, headache, dizziness, chest tightness, numbness tinnitus and other symptoms will disappear.

After about 3 months of treatment, you can do blood detect, or CT detect, high blood pressure, high blood viscosity, high cholesterol will get back to a normal level. Otitis Media deafness, tinnitus or Meniere's syndrome will have a big improvement.

Function and Performance:                                                                                                                                                                                         

1. reducing the blood viscosity;

2. accelerating the blood circulation within the nasal tissues.

3. enhancing local blood oxygen saturation,

4. accelerating the absorption and metabolism of nasal tissue to inflammatory substances.

5. eliminating and reducing the nasal obstruction caused by nasal swelling.

6. promoting the secretion of lysozyme and phagocytes within the nasal mucosa,

7. improving the immunization and sterilization function of the nasal mucosa.

8. improving the nasal antivirus/germs ability and the antianaphylaxis ability.

9. accelerating the convergence of the damaged nasal mucosa,

10. repairing damaged blood capillary and prevent the regular nosebleed.

11. accelerating and improving the swinging of cilia on the nasal mucosa.

12. enhancing the nasal function and strengthening the detoxification ability of the nasal mucosa.
