blood plasma is represented by its liquid part, which are formed elements .Blood plasma contains from 50 to 60% depending on various factors.Its acid-alkaline balance is approximately 7.35 pH.This liquid is slightly turbid or clear homogeneous yellow substance which after the deposition process corpuscles collected in the upper part of the vessel.Also plasma intercellular substance is blood and adipose tissue.

The composition includes plasma water (90%), the proteins that constitute about 7% of its weight, mineral and organic compounds. albumin, globulin and fibrinogen are the main proteins that are part of the plasma, and dozens of other proteins are included in its composition. Fibrinogen - a crucial protein involved in blood clotting, which is a result of this process is converted to fibrin .After coagulation of blood plasma called serum , it contains antibodies , called immunoglobulins .In plasma and high dissolved nutrients, enzymes, vitamins, hormones final and intermediate

products of metabolism , inorganic ions.

gathering of donor plasma - an important point, which is an extensive practice.For its collection method used plasmapheresis .Its essence is as follows.Donor blood is purified from erythrocytes , collected in a special container, and then erythrocytes blood returned to the donor.

blood plasma that is rich in platelets , today is widely used in medical practice as a stimulation of tissue regeneration and healing after various destructive factors.PRP, now forms the basis of multifunctional techniques Plazmolifting , used in cosmetology and dentistry.Also from the plasma of blood of animals and humans is prepared medicinal and cosmetic preparations: albumin, gamma globulin, dry blood plasma fibrinogen etc.Recently, the use of more widely used than whole serum and its fractions, constituents.

for research and diagnosis of certain diseases can be used special serum - labeled phosphors, radionuclides or enzymes.

plasma transfusions can be used for rapid healing of burns, cirrhosis, septic diseases.plasma transfusion begins to crossmatch blood donor and patient.

Introduction even large volumes of plasma (50 ml) together with coagulation preparations gives good results in bleeding, increased vascular tone.Besides stopping bleeding, transfusion of blood plasma is used in order to compensate for any lack of blood components or the liquid portion.

In the event that the patient is increased clotting, blood transfusion is not done because of the risk of complications, including death.

study of blood plasma is of great importance for the diagnosis of various pathologies and diseases, such as diabetes , a deviation from the normal level of blood components, with the appearance of abnormal proteins, for example, when rheumatism formed C-reactive protein.
