down-regulation in vivo of liver plasma membrane receptors for prostaglandin e ( pge ) was investigated in sprague-dawley rats using the 16,16-dimethyl analogue of pge2 , this analogue was used for subcutaneous injections because it escapes the rapid pulmonic degradation characteristic of pge and was recognized well by liver plasma membrane receptors .
