Comparative study of the histology, histochemistry and ultramorphology of the proventriculus in the cephalotini tribe (Hymenoptera: Formicidae)
The use of optical microscopy and scanning electron microscopy propitiated the comparative examination of the nature of the histology, histochemistry and ultramorphology of the proventriculus bulb of Cephalotes atratus, ...
Histology and histochemistry of the ventriculus of Dolichoderus (=Monacis) bispinosus (OLIVIER, 1792) (Hymenoptera : Formicidae)
(Elsevier B.V., 2006-01-01)
In this study we histologically and histochemically describe the ventriculus of Dolichoderus bispinosus. The epithelium consists of two basic cell types, highly basophilic generative cells, and digestive cells. The latter ...
Histology, histochemistry and stereology of the adipose fin of Prochilodus lineatus
The adipose fin is small, nonpared, and usually located medially between the dorsal and caudal fin. Its taxonomic occurrence is very restrict; thus, it represents an important trace for taxon distinction. As it does not ...
Ultrastructure and histochemistry of the mineral concretions in the midgut of bees (Hymenoptera: Apidae)
(E J Brill, 1997-01-01)
Mineral concretions in the digestive cells of bees were examined under transmission electron microscope and histochemically. Ultrastructure shows two types of mineral deposits: 1) mineral concretions which are organized ...
Glandular trichome diversity on leaves of Lippia origanoides and Lippia stachyoides (Verbenaceae): morphology, histochemistry, and ultrastructure
(Canadian Science Publishing, Nrc Research Press, 2015-05-01)
Despite the ecological and medicinal importance of glandular trichomes in Verbenaceae, information on their structure, mainly at the subcellular level, is sparse. We analyzed the morphology and histochemistry of glandular ...
ISTOCHEMICAL STUDY IN THE EPIDIDYMIS OF THE DOG (Canis familiaris, L.)
(Sociedad Chilena de Anatomía, 2000)
Prostatic stromal microenvironment and experimental diabetes
The diabetes causes alterations in various organ systems, including the male accessory sex glands. The prostate is very important in the reproductive process and it is a frequent target of malignant changes. The aim of ...
Seasonal Variation in the Histomorphology and Histochemistry of Ampulla of Vas Deferens of Gaddi Goat and Gaddi Sheep
(Sociedad Chilena de Anatomía, 2008)
Comparative morphology of the midgut of three species of Cephalotes (Hymenoptera, Formicidae, Myrmicinae)
Studies of histological nature, histochemistry and ultra-morphology of the midgut of three species of ants belonging to the genus Cephalotes (atratus, clypeatus and pusillus) were performed. In histology H-E was employed, ...
