GILDING METHODS — the ways of histologic processing of fabrics salts of gold used preferential for studying of nervous and muscular tissue. In gistol, the equipment 3. m usually apply to toning of drugs, impregnirovanny silver, use independent methods of impregnation by gold less often (see. Impregnation ).
For gilding use 0,5 — 1% solution of chloric gold (AuCl 3 ) or zolotokhloristovodorodny to - you are H (AuCl 4 ) - 4H 2 O. During the toning of cuts, impregnirovanny silver (see. Silverings methods ), weakening of impregnation of fine nerve fibrils and synoptic structures can be noted a nek-swarm. Cuts place in divorced solution of chloric gold (usually several drops of 1% of solution for 10 ml a dist, waters, at some modifications apply more konts. solutions — to 1%) it is frequent with addition of a small amount acetic to - you. Cuts from brownish-yellow become gray and steel or reddish-violet; impregnirovanny silver elements at the same time gain black or dark-violet color (see. Bilshovsky-Groce-Lavrentiev method ).
Impregnation by gold is applied to identification of nervous cells with their shoots and the terminations, elements of a neuroglia, connective tissue fibers, and also myofibrils and so forth (see. Ramón-and-Kakhalya methods , Ranvye methods ).
For identification of connecting fabric in c. N of page apply Biondi's way: the cuts made by a freeze-etch method pickle in solution of potassium permanganate then they are processed mix of potassium sulfate with oxalic to - that and gild in mix of chloric gold with corrosive sublimate. All manipulations during the work with chloric gold should be made purely washed up glass needles.
