[Prolongation of the survival of skin allografts by intravenous injection of neuraminidase-treated donor bone marrow cells in rats].

Objective: To optimize the best concentration of neuraminidase (Neu) that enhances the migration of neuraminidase (Neu)-treated donor bone marrow cells (dBMCs) to the liver, and observe the influence of short-term cyclosporin A(CsA) application combined with intravenous injection (i.v.) of Ne treated dBMCs on the survival of skin allografts.

The correlation between striatal dopamine D2/D3 receptor availability and verbal intelligence quotient in healthy volunteers.

Background: Although a correlation between the central dopaminergic system and intelligence may exist, the results from imaging studies remain inconclusive. The aim of this study was to explore the relationship between striatal dopamine D2/D3 receptor availability and verbal intelligence quotient (VIQ) using single photon emission computed tomography (SPECT).

Method: Striatal D2/D3 receptor availability of 64 healthy subjects was determined with the [123I]iodobenzamide ([123I]IBZM) ligand.

Direct evidence of the existence of specific LPS binding sites on vascular endothelial cells.

Objective: To investigate the binding characteristics of endothelial cell (EC) with LPS free from the participation of serum factors.

Methods: Laser confocal microscope was employed in the observation of the binding of EC with FITC-LPS. The KD and the binding sites of each EC were calculated by radioligand binding assay of receptors (RBA) using [(3)H]-LPS.
