Histo-biochemical correlation in the oviduct of Bufo arenarum (Hensel). 1976

B A Méndez, and A R Moreno, and J M Olavarría, and Porrúa

A histo-biochemical correlation was carried out in oviducts of Bufo arenarum (Hensel), in trophic animals in the preovulatory period. Histochemical techniques were used to detect acidic mucoproteins, whereas complex mucopolysaccharides were biochemically assayed, thus simplifying the histologic methodology. The existence of acetylhexosamines, hexoses, phosphate and sialic acid in the oviduct was put in evidence through histochemical and biochemical methods. Results show a high content in sialic aicd, total phosphate and acetylhexosamines in the middle and terminal portions of the preconvoluted zone. Sialomucins, acetylhexosamines and hexosamines show a maximum in the last loops of the convoluted zone, coincident with clearly determined histologic areas. All components detected exhibit minimal values in the proximal and distal intermediate zones. Results found for phosphate show it is combined, and determines the reactivity to the stains used. This type of mucin has not been found in other species.

UI	MeSH Term	Description	Entries
D009865	Oocytes	Female germ cells derived from OOGONIA and termed OOCYTES when they enter MEIOSIS. The primary oocytes begin meiosis but are arrested at the diplotene state until OVULATION at PUBERTY to give rise to haploid secondary oocytes or ova (OVUM).	Ovocytes,Oocyte,Ovocyte
D010057	Oviducts	Ducts that serve exclusively for the passage of eggs from the ovaries to the exterior of the body. In non-mammals, they are termed oviducts. In mammals, they are highly specialized and known as FALLOPIAN TUBES.	Oviduct
D010710	Phosphates	Inorganic salts of phosphoric acid.	Inorganic Phosphate,Phosphates, Inorganic,Inorganic Phosphates,Orthophosphate,Phosphate,Phosphate, Inorganic
D002022	Bufo arenarum	A species of the true toads, Bufonidae, found in South America.	Toad, Argentine,Argentine Toad,Argentine Toads,Toads, Argentine

D006595	Hexosamines	AMINO SUGARS created by adding an amine group to a hexose sugar.	Hexosamine
D006601	Hexoses	MONOSACCHARIDES whose molecules contain six carbon atoms, such as GLUCOSE and FRUCTOSE. They generally have the chemical formula C6H12O6.	Hexose
D006651	Histocytochemistry	Study of intracellular distribution of chemicals, reaction sites, enzymes, etc., by means of staining reactions, radioactive isotope uptake, selective metal distribution in electron microscopy, or other methods.	Cytochemistry
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
