Localization of gold particles and the shapes formed by their conglomeration were investigated in RA-afflicted articular synovia of 31 cases after administration of small dosis of gold sodium thiomalate (GST) (in 23 cases less than 10 mg and in 8 cases less than 25 mg at a time were administered) with electron probe microanalyzer and electron microscope. In 9 cases in which less than 10 mg of GST at a time was administered and synovial biopsies before and after administration of GST were performed, relation between clinical finding with Lansbury index as its parameter, synovial histology, localization and the shapes of gold particles was investigated. Furthermore, the observation that proliferation of cultured endothelial cells of umbilical veins was inhibited by administration of small dosis of GST having taken into consideration, vascular density of superficial synovial layer and morphological change of EC were measured, which led to the following conclusion. 1. Gold particles were mostly found in lysosomes of macrophages located in deeper layer of articular synovia in contract to cases with administration of greater dosis of GST where they were said to be found mostly in lining cells of synovia. However, no marked difference in the shape of precipitated gold particles was observed. 2. Lansbury index coincided with histological change in 8 of 9 cases, but not with localization and shape of gold particles. 3. Vascular density in the superficial layer of articular synovia after administration of GST increased in cases with progressing histological change, but did not decrease in cases with improving histology. 4. Decrease in the height of EC, shrinkage and flattening of nuclei were seen in all cases after administration of GST. 5. Findings above described seemed to suggest that GST inhibited synovitis by causing flattening of EC, rather than inhibition of new vascular formation.
