In basis of these diseases is a the same chart and they are named illnesses of haemocoagulation . Foremost, you must understand in detail the chart of haemocoagulation, after that you will able to understand essence of diseases.A haemocoagulation flows by the stages: selection of thromboplastin from the certain cellules of blood, which are able to stick together--------converting of protrombin( blood's albumen) into an enzyme thrombin under the influence of thromboplastin----------------converting of soluble albumen Fibrinogenum into an insoluble fibrin under influence of thrombin. A blood clot is created from filaments and clots of fibrin which helps us to stop up a blood vessel and will stop bleeding .This thrombin is a dangerous thing!)In blood , as you understand, it is absent.And a healthy man "answer"s to appearance of it in blood defending oneself anticoagulant matters (for example, by a heparin) The diseases, what are indicated by you, can arise up, as they say, on the bowl of the scale-failing or even one preponderance of these matters on any of the stages of haemocoagulation.All-known is that the diseases of the second type arise up mainly as a result of incest.There are:
-haemophilia A, haemophilia B(illness of Kristmas-defect of matter, depressing coagulation), boys are ill in generally(probably, you know about this royal illness)
- defect of predecessor of thromboplastin(extended time of coagulation and abnormal absorption of protrombin) . More frequently this illness meets in New York, than in London).The variety of this disease is a defect of factor of Khageman. Transmitters are healthy people -clinically, but their blood during coagulation takes away the working hours of laboratory assistant))
-vascular haemophilia of Villebrand- womanish illness, is caused by the lack of antigemofil globulin with the defect of capillaries.
There are a few cases of rare diseases, for example, for 3 persons it was found out illness of lack of protrombin, ten of cases of abnormal transformation of albumens in a chart, found out illness of Styuart for 6 children from a husband and wife (related by blood) which were so wise as to do 12 children ( maybe, specially for experiments)))
