An immunoregulatory agent containing a regulatory agent that regulates Dedicator of cytokinesis 2 (DOCK2)-mediated Rac activation as an active ingredient is provided.

Immunoregulatory agent

A medical polymer material in which a phosphate group having a C&#x2014;O&#x2014;P chemical bond including elemental C in a main chain of a structural formula is present on a surface of a polymer material substantially free of phosphate and hydroxy groups except for ends in the structural formula.

Medical polymer material having excellent bone-bonding property

A medical use honeycomb structure having a plurality of through-holes extending in one direction, wherein an outer peripheral section of the medical use honeycomb structure has a through-hole groove formed by incomplete side walls of the through-hole, and a through-hole inlet adjacent to the through-hole groove.

Medical use honeycomb structure

To provide a method for producing a calcium carbonate block for medical use which is useful as a bone substitute or a bone substitute raw material needed in medical care, which is a method for producing a calcium carbonate block that satisfies the following desired properties: 1) the calcium carbonate block has excellent mechanical strength; 2) the calcium carbonate block can be produced by a simplified production method; 3) the calcium carbonate block contains no impurity; and 4) the calcium carbonate block has high reactivity. A method for producing a calcium carbonate block, comprising a step of shaping a water-containing calcium hydroxide block and a carbonation step of immersing the calcium hydroxide block in a carbonate ion-containing aqueous solution.

Method for producing calcium carbonate block

The present invention provides: a method for producing a shaped product comprising octacalcium phosphate and having a volume of 2.0 mmor more, comprising immersing a precursor ceramic composition containing at least one of Ca and POin composition, having a solubility in HO higher than that of octacalcium phosphate, and having a volume greater than 2.0 mm, in a solution containing a component which is not contained in the precursor ceramic composition, among the components Ca, POand HO, which are components of octacalcium phosphate to allow the precursor ceramic composition to react, thereby converting at least a part of the precursor ceramic composition into octacalcium phosphate; and the like.
