I recall thinking ludicrously that I was staining Howie's beloved hardwood floors with my blood and puke.
Blood had bloomed, staining the left side of his abdomen and down his hip.
She could feel the color staining her cheeks again.
The study of the differentiation of protoplasm was at that time seldom undertaken, and no particular attention was paid either to fixing it, to enable staining methods to be accurately applied to it, or to studying the action of chemical reagents upon it.
Careful staining shows that the granular substance of the interior really consists of a large number of delicate rod-like bodies.
The staining reactions of the various parts of the nucleus depend to some extent upon their chemical constitution.
B~it the staining reactions of nuclei may vary at different stages of their development; and it i~ probable that there is no method of staining which differentiates with certainty the various morphological constituents of the nucleus.
2, L), a nucleolus appears, a nuclear membrane is formed, and daughter nuclei are thus constituted which possess the same structure and staining reactions as the mother nucleus.
Staining reagents can also be used to differentiate lignified cell-walls.
The basis of __________ these methods consists in causing a swelling of the cell-wall by means of sulphuric acid or zinc chloride, and ___________________ subseauent staining with Hoffmanns ~a:~
They are preceded over the whole area by a much simpler form of burial marked by the practice of staining the bones with red ochre, and the presence of one or two rude pots and nothing more: yet that some were tombs of great chiefs is shown by the great size of the barrows heaped over them.
Usually the cytoplasm shows a marked affinity for the acid stains, but the different bodies found in the cell may show great variation in their staining reactions.
The fat in this condition is readily recognized by the usual microchemical and staining reactions.
As fat is a food element essential to the carrying out of the vital energies of the cell, a certain amount of fatty matter must be present, in a form, however, unrecognizable by our present microchemical and staining methods.
This pigment is of a light yellow colour, and contains a fatty substance that reacts to the fat-staining reagents.
The hyaline material, unlike the amyloid, does not give the metachromatic staining reactions with methyleneviolet or iodine.
Now the cellular pathology of the blood, investigated by the aid of modern staining methods, is as important as that of the solid organs; no clinical investigator - indeed, apart from research, no practitioner at this day - can dispense with examination of the blood for purposes of diagnosis; its coagulability and the kinds and the variations of the cells it contains being evidence of many def i nitely morbid states of the body.
In hydatid disease there is, as a rule, a marked increase in the number of those white corpuscles which possess a specially staining affinity with the dye eosin, and are therefore known as eosinophile cells.
Munich has long been celebrated for its artistic handicrafts, such as bronze-founding, glass-staining, silversmith's work, and wood-carving, while the astronomical instruments of Fraunhofer and the mathematical instruments of Traugott Lieberecht von Ertel (1778-1858) are also widely known.
What then happened was very natural: imitations of the old wares were produced, and having been sufficiently disfigured by staining and other processes calculated to lend an air of rust and age, they were sold to ignorant persons, who labored under the singular yet common hallucination that the points to be looked for in specimens from early kilns were, not technical excellence, decorative tastefulness and richness of color, but dinginess, imperfections and dirt; persons who imagined, in short, that defects which they would condemn at once in new porcelains ought to be regarded as merits in old.
They have from very early times been resorted to as a means of staining the hair of a dark colour, and they are the base of the tattooing dye of the Somali women.3 The gall-making Hymenoptera include, besides the Cynipidae proper, certain species of the genus Eurytoma (Isosoma, Walsh) and family Chalcididae, 'e.g.'
In many forms deep-staining grains or granules, of a chromatoid nature and of var y ing size, are to be seen in the cytoplasm.
Characteristic yellow staining of the skin round the mouth from the formation of xanthoproteic acid serves to distinguish it from poisoning by other acids.
Darwen is a centre of the cotton trade and has also blast furnaces, and paper-making, paper-staining and fire-clay works.
Matruchot has used them for staining the living protoplasm of other fungi by growing the two together.
The study of the nucleus of yeast-cells is rendered difficult by the presence of other deeply staining granules termed by Guillermond naetachromatic granules.
As a result the fatigued cells appear shrunken, and their reaction to staining reagents alters, thus showing chemical alteration.
Scattered in the protoplasm are usually one or more deeply-staining granules.
The protoplasm itself may be tinged with colouring matter, bright red, yellow, &c., and may occasionally contain substances other than the deeply-staining granules.
Attention has accordingly been directed to the deeply-staining granules mentioned above, and the term chromatin-granules has been applied to them, and they have been considered to represent a rudimentary nucleus.
These H structures are invisible, with ordinary illumination in living cells or unstained preparations, and can only be made clearly visible by special methods of preparation and staining first used by Loffler.
Such microscopic examination requires the use of the finest lenses and the application of various staining methods.
Sometimes a simple watery solution of the dye is sufficient, but very often the best result is obtained by increasing the staining power, e.g.
This is the case in the methods for staining the tubercle bacillus and also in Gram's method, the essential point in which latter is the treatment with a solution of iodine before decolorizing.
Gault); (5) oxides of iron (staining the clay bright red when ferric oxide, red ochre; yellow when hydrous, e.g.
