In healthy subjects, the glucose load after placebo induced an insulin response of 7.4 +/- 1.0 and 11.3 +/- 1.4 microU ml-1 min-1 mg-1 dl-1 for the first and second phases, respectively, and an insulin sensitivity evaluated to be 4.7 +/- 0.3 min microU-1 ml-1.

In diabetic subjects the insulin response to the glucose load after placebo was markedly decreased (2.2 +/- 0.5 and 2.5 +/- 0.3 microU ml-1 min-1 mg-1 dl-1, respectively) as was the insulin sensitivity (2.5 +/- 0.3 min microU-1 ml-1).

Scatchard transformation of saturation binding experiments revealed that the KD and Bmax for [125I]ET-1 and [125I]ET-3 to membranes from ciliary body were 41.7+/-9 pM and 236+/-20 fmol mg-1 protein and 37. 8+/-0.4 pM and 160+/-2.0 fmol mg-1 protein, respectively.

Competitive experiments in the presence of cyclic pentapeptide BQ123 (selective for ETA receptors) and BQ3020 (selective for ETB receptors), demonstrated the existence of ETA and ETB receptors in a ratio of 35:65.

Cross-linking of [125I]ET-1 and [125I]ET-3 to ciliary body membranes resulted in the labeling of two bands with apparent molecular masses of 52 and 34 kDa, suggesting that ETA and ETB receptors have similar molecular mass.

Autoradiographic results show that specific [125I]ET-1 binding sites, displaced by BQ123 and BQ3020, are localized to the ciliary epithelium, supporting the idea that ETA and ETB subtype receptors exist in this tissue.
