Bronchiolitis obliterans is a rare and life-threatening form of fixed obstructive lung disease in which the bronchioles are plugged with granulation tissue. Bronchiolitis obliterans may develop in the allograft lung through several means. There are four subtypes of Bronchiolitis obliterans first is cellular bronchiolitis second is bronchiolitis obliterans and last is bronchiolitis obliterans with intraluminal polyps (proliferative bronchiolitis obliterans). Bronchiolitis obliterans is sometimes confused in the public mind with bronchiolitis obliterans organizing pneumonia (BOOP), a completely different pulmonary disorder. Bronchiolitis obliterans is a lung disease characterized by fixed airway obstruction. Some possible cause to include collagen blood vessel disease, the transplant rejection in the organ transplanting patient, the viral infection, the medicine responded, is immature the ambition and to the toxic smoke introduction complication, with the exposition, has: Diacetyl, sulphur dioxide, nitrogen dioxide, ammonia, chlorine, thionyl chloride, methyl alcohol isocyanate, hydrofluoride, hydrogen bromide, Hydrogen chloride, hydrogenation sulfur, oxychloride carbon, polyamide amine dye, with ozone.

Millions of people are affected by high blood pressure (hypertension), a condition in which blood travels through the body’s arteries at a pressure too high for good health. High blood pressure in the arteries that supply the lungs is called pulmonary hypertension (PHT). The blood pressure measured by cuff on your arm isn’t directly related to the pressure in your lungs. The blood vessels that supply the lungs constrict and their walls thicken, so they can’t carry as much blood. Although the terms primary pulmonary hypertension (meaning of unknown cause) and secondary pulmonary hypertension (meaning due to another medical condition) still persist in materials disseminated to patients and the general public, these terms have largely been abandoned in the medical literature.

The heart works harder, trying to force the blood through. Nearly 50 million Americans have high blood pressure (also known as hypertension). There are two main kinds of pulmonary hypertension. The most common cause of pulmonary hypertension is left heart failure leading to pulmonary venous hypertension (WHO Group II).

Cord blood, also known as placental blood, is the blood that remains in umbilical cord and placenta following a live birth. There are 3 sources of stem cells: umbilical cord blood, embryonic cells and bone marrow. Adult stem cells from bone marrow have limited uses while embryonic stem cell research is a major area of controversy. Umbilical cord blood stem cells are more proliferate and can be successfully substituted for embryonic stem cells in research and treatment.

There are advantages to using cord blood stem cells:

- It is easy to collect cord blood without posing any risk to the newborn or mother. Cord blood banking allows stem cells to be frozen and stored for immediate use in the future.

- As cord blood stem cells are young and less mature, they can be transplanted even when there is a half match. Bone marrow transplant requires perfect match between donor and recipient.

- Cord blood stem cells are less likely to attack the patient’s own tissues than bone marrow stem cells.

Umbilical cord blood stem cells have the potential to develop into many types of cells such as muscle, nerve or blood cells. Cord blood stem cells are able to regenerate immune system and replace damaged or diseased cells. Currently, cord blood is being used to treat blood disorders, certain cancer and auto-immune diseases. Researchers are looking into the ability of cord blood stem cells to replace or repair damaged tissues and organs. Since these cells can repair damaged tissues, they could be used to treat Parkinson, heart disease, stroke, spinal cord injury, multiple sclerosis and diabetes.

In recent breakthroughs of stem cell research, scientists have been able to differentiate cord blood stem cells into a type of lung cell, grow mini liver and develop bone and cartilage. These preliminary findings show that cord blood stem cells offer great potential in the treatment of lung and liver diseases, and acute kidney failure. Cord blood cells can potentially repair organs damaged by illness or disease. Scientists are hopeful that these cells will regenerate into organs in the human body. A better understanding of how normal development occurs and disease processes can enable researchers to develop new and improved approaches to treating diseases and injuries.
