A biochemical information processing apparatus includes a storage means storing biochemical information, input means for accepting input of data, reaction scheme detection means for detecting a chemical reaction scheme involving a compound, based on the data, and display means for displaying a reaction scheme diagram of the chemical reaction scheme. The storage means includes a compound information file, an enzyme information file, and a relation information file. The relation information file stores a list showing the relation among compound numbers of compounds, enzyme numbers of enzymes with either pertinent compound being a substrate, and enzyme numbers of enzymes with either pertinent compound being a product. The reaction scheme detection means includes a first process portion for preparing canonical data of the compound from the data and searching the compound information file based thereon to read out a compound number. It also includes a second process portion for reading an enzyme number of an enzyme with the compound being a substrate or a product, a third process portion for reading a compound number of another compound constituting a reaction system with the enzyme and additional information of the enzyme, and a fourth process portion for indicating a reaction scheme diagram of the compound on the display means.

An artificial dental root comprised of a particulate or powdered form of synthetic hydroxyapatite or calcined or sintered synthetic hydroxyapatite or a mixture thereof and an organic matrix, the surface area of said artificial dental root to be brought into contact with a bone being composed of both a phase of said hydroxyapatite and a phase of said organic matrix. The artificial dental root is prepared by blending said hydroxyapatite with said organic matrix and molding the blend. The artificial dental root has moderate affinity for a bone and high mechanical strength.

Process for preparing an artificial dental root

Disclosed is a composite implant material comprising a sintered apatite material and a thermoplastic or thermosetting resin. Said composite material is prepared by forming a sintered apatite material and filling or impregnating a thermoplastic or thermosetting resin into the pores or holes of the sintered apatite material, which have been formed during the formation of said sintered material or perforated after the formation thereof. Said composite implant material has controlled compatibility to bone as well as excellent physical strength.

An electromagnetic wave absorbing material comprising as a conductive material hollow carbon microspheres which are prepared by the use of a coal-base or petroleum-base pitch material and which have a non-cohesive property with one another, and as a matrix a non-conductive material having a specific resistance of greater than 10.sup.3 .OMEGA. cm, the conductive material being mixed with the non-conductive material and the mixture being formed into moldings. The resultant composite moldings exhibit a satisfactory complex dielectric constant, so that the composite material is applicable, for example, as a waveguide microwave absorber, a microwave pollution preventive microwave absorber, a microwave absorber for microwave heating range, or a microwave absorber for an antenna.
