As the result of various investigations, to which, reference will be given in the text of this communication, it is possible to divide the substances which accompany cellulose in the cell-walls of plants among this following groups:— (i) The lignins. (ii) The hemicelluloses. (iii) The pectins. It cannot yet be claimed that any one of the products which can be assigned to these groups has been isolated in the form of a definite chemical entity (with the exception, perhaps, of some products in group iii). There are, however, certain characteristics common to each group, to which brief reference must be made. The lignins appear to be products of high molecular weight, which can be extracted by various somewhat drastic methods from woody tissues. The products obtained by different methods vary in their properties, but they appear to give definite colour reactions with a number of reagents.

Fibrinogen Degradation Products

SummaryThe last phase of the clotting mechanisms was investigated in cord blood of 118 mature newborns.The most prominent finding was a prolonged thrombin time, not due to heparin. It was accompanied in most cases by a low fibrinogen and in some by a gelatinous appearance of the clot and a paracoagulation of the serum. This association was found to be usually due to in vitro fibrinogenolysis with consequent appearance of fibrinogen split products.In 9 cases the prolonged thrombin time was not obviously due to fibrinogen degradation products. The possibilities of the presence of high molecular weight fibrinogen degradation products or of a special characteristic of cord blood fibrinogen leading to a delayed fibrinogen-fibrin conversion are considered.
