Subcellular distribution of terminal alpha-D- and beta-D-galactosyl residues in Ehrlich tumour cells studied by lectin-gold techniques.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
We have studied by high resolution in situ light and electron microscopic lectin-gold techniques the subcellular distribution of alpha-D-Gal residues using the Griffonia simplicifolia I-B4 isolectin and compared it with that of beta-D-Gal residues as detected with the Datura stramonium lectin in Ehrlich tumour cells grown as ascites or monolayer. The microvillar but not the smooth plasma membrane regions were labelled with the Griffonia simplicifolia I-B4 isolectin whereas both plasma membrane regions were equally well labelled with the Datura stramonium lectin. Elements of the endocytotic/lysosomal system such as coated membrane invaginations and vesicles, early and late endosomes and secondary lysosomes were positive for both alpha-D-Gal and beta-D-Gal residues. A particular feature of Ehrlich tumour cells is an elaborate tubular membrane system located in the pericentriolar region which is labelled throughout by both lectins and represents part of the endosomal system. In the Golgi apparatus labelling with both lectins was observed to commence in trans cisternae which is indirect evidence for a joint distribution of the sequentially acting beta 1,4 and alpha 1,3-galactosyl-transferases.
