Deficiency of Factor VII is relatively rare and inherited as an autosomal recessive disorder. Deficiency of Factor VII has been reported to be associated with bond abnormal bleeding and thrombotic tendencies. Deep vein thrombosis and pulmonary emboli have been reported in affected individuals. There is a very high frequency of Factor VII deficiency in people with the Dubin-Johnson syndrome, which is a congenital disorder of Hver function.

The exact recipes for these products are of course proprietary, but the development of some of these gels has required years of effort to develop. Since the early 1980s, well over 1000 gel batches have been made and we are always looking for better ways to manufacture our resins. For the reader interested in a more detailed description of gel making, see Potschka and Dubin (2) as well as the excellent older work (1).
