The ultrastructural localization of glycosaminoglycans GAGs in the developing human outflow apparatus was investigated. The aqueous outflow system from human eyes at 26th and 36th fetal week and 2 years of age was stained with ruthenium red to identify GAGs with the transmission electron microscope. Luminal surface of the inner wall of the Schlemm's canal, basal lamina of the endothelial cells, basal lamina-like material, amorphous substances and collagen fibrils in juxta-canalicular tissue were associated with ruthenium red-stainable material. The basal lamina of the endothelial cells of Schlemm's canal was stained less obviously in 2-year-old trabecular tissue.

When a thread runs as long as the WITP one has, there are bound to be a few jokes that will be lost on newbies to the thread. So this is an attempt to catagorize, and explain as many of them as can be remembered. This is probably the oldest running joke. It seemed in the early months of the thread, Grey was destined, through bad decisions, bad UI and plain bad luck, to sink every British Ship possible.
