Machines and equipment (almost one-half of the value), and also raw materials (iron ore, coal, and oil), predominate among imports. The United States, Great Britain, Italy, and West Germany accounted for 40–45 percent of Argentina’s foreign-trade turnover in 1965–66.

Grocott's Methenamine Silver Staining Protocol:Principle Chromic acid oxidation forms aldehydes from fungal cell wall polysaccharide components, which are subsequently demonstrated by reduction of an alkaline hexamine-silver complex. The reaction may be compared to that of the periodic acid Schiff reaction, (see PAS).Grocott's alkaline hexamine-silver solution represents a vehicle which, upon ...

Abstract ‘Argentaffinity’, as opposed to ‘argyrophilia’, denotes the reduction of silver salts to metallic silver by tissue or cell component per se, without addition of any extraneous reducing substance and in the dark.Aldehydes, which are known to reduce diammine silver, are not needed for the argentaffin reaction to take place; thus, staining after ethanol or Carnoy fixation was ...

Medical definition of argentaffin: depositing reduced silver from ammoniated silver hydroxide solutions —used of certain cell granules containing phenols or polyamines.

Carcinoid tumors of the gastrointestinal tract have received more attention in the literature than the frequency of their occurrence would justify. This is, no doubt, because of the unusual clinical and pathological characteristics of these tumors. The origin of the carcinoid tumors has been the...

Staining is a technique used to enhance contrast in samples, generally at the microscopic level. Stains and dyes are frequently used in histology (the study of tissue under the microscope) and in the medical fields of histopathology, hematology, and cytopathology that focus on the study and diagnoses disease at a microscopic level. Stains may be used to define biological tissues (highlighting ...

Argentaffin cells and melanin possess the ability to bind silver from a silver solution and reduce to visible metallic silver without the need for a reducing agent. The Fontana-Masson Stain Kit can be used for frozen or paraffin embedded sections. Benefits. 30x faster microwave procedure reduces melanin incubation time from 30 minutes to 1 minute.

nitrates: A family of chemically stable forms of inorganic nitrogen, which are formed as part of the natural breakdown of organic matter. Nitrates are ingested in vegetables and absorbed from the gastrointestinal tract; an estimated 25% of absorbed nitrates are released into the saliva, 20% of which are converted into nitrites. Nitrates are ...

Stains for argentaffin cells, granules, carcinoid tumors, and melanin in 60 minutes.Argentaffin cells possess the ability to bind and reduce silver to a visible metal without requiring a reducing agent, allowing this stain to be performed with fewer steps than other silver stains. An Ammoniacal Silver Developer Solution serves as the primary stain, producing brown to black melanin granules ...

Carcinoid tumors of the appendix and small intestine have been repeatedly described in the literature. 1 It is generally conceded that these neoplasms arise from the so-called argentaffin cells present in the mucosa. 2 Argentaffin cells are also normally present in the stomach and colon. 3 As the name implies, these cells, and the carcinoids derived from them, contain cytoplasmic granules ...

Melanin stains. Melanin is normally found in the skin, eye, and substantia nigra. It may also be found in melanomas. The commonly used Fontana-Masson ("melanin stain") method relies upon the melanin granules to reduce ammoniacal silver nitrate (but argentaffin, chromaffin, and some lipochrome pigments also will stain black as well).

Lysosomes stain with the argentaffin reaction after fixation with glutaraldehyde followed by osmium tetroxide. The reaction works well both at the level of the light and electron microscope. Control experiments show that this argentaffinity is caused by reduced osmium tetroxide.

Lactic acid bacteria (LAB) are Gram-positive bacteria that are natural inhabitants of the gastrointestinal (GI) tracts of mammals, including humans. Since Mechnikov first proposed that yogurt could prevent intestinal putrefaction and aging, the beneficial effects of LAB have been widely demonstrated.
