Following castration, the nucleus of the dark cells of the subcortical portions of the collecting tubules in the rat kidney showed two types of morphological alterations: 1) Decomposition of the nuclear membrane in a circumscribed area. This phenomenon is independent of the sex of the animal and becomes more frequent up to the 30th day after castration.

Nature, 1962
IN the kidneys of various species, the collecting tubules are composed of two types of cells. These were apparently first seen by Heidenhain1, and described in subsequent years as light and dark (intercalated) cells2. The name given to these cells alludes to the fact that the cytoplasm of the dark cells stains with various commonly used dyes more ...

ESTIMATION OF TIME SINCE DEATH BY HISTOLOGICAL EXAMINATION OF COLLECTING TUBULES IN HUMAN KIDNEY.
International Journal of Medical and Biomedical Studies, 2019Background: The current research histological changes in the Collecting tubules were examined at various postmortem intervals in the deceased human. In these research histological changes of tissue after death is influenced by P.M.I. atmospheric temperature and humidity, external and internal factors. Aim: To study the time since death by post ...

[Morphometric analysis of the effects of vasopressin in the rat kidney collecting tubules].
Rossiiskii fiziologicheskii zhurnal imeni I.M. Sechenova, 1999A significant increase in the water permeability was found in the rat outer medullary collecting duct (OMCD) cells in presence of 10-7M of vasopressin. The latter caused a decrease in the OMCD cell volume in isoosmotic medium in adult rats. In pups, the water permeability of the OMCD cells was very high.

Light and electron microscopic techniques were employed to characterise the various cell types found in the distal tubules, collecting tubules and collecting ducts in the kidneys of wild starlings (Sturnus vulgaris). There was a gradual change in cell characteristics along the length of the distal tubule. A short transition zone was identified, between

AbstractIn female Podarcis taurica the kidney collecting tubule always consists entirely of mucous‐secreting cells. In males it has a seasonally variable sexual segment and a non variable mucous‐secreting segment. In April the sexual segment is composed of columnar cells with cytoplasm rich in ribosomes and Golgi bodies and apical clusters of large ...

The role of plasma membrane fluidity in the regulation of kidney tubule water permeability has been uncertain. We have used new methods to image the fluorescence anisotropy of fluidity-sensitive fluorophores (Fushimi, Dix, and Verkman. Biophys. J.

Hypokinesia (reduced motor activity) induces significant tissue morphological changes, however, it is not known if hypokinesia (HK) could contribute to morphological changes in the kidney. Measuring the nuclear size in the inner medullary collecting ducts on the kidney of rats the aim of this investigation was to disclose kidney morphological changes ...

The kidney is a composite organ, the specific activities of which are attributable to the peculiar construction of the individual components of the glomerula, nephrons and collecting tubules. This comprehensive review will address the essential physiological mechanisms of urine formation, such as filtration, secretion, reabsorption and concentration ...

Surface Epithelia. Simple Columnar Epithelium. Example: Collecting Tubule of the Rat Kidney
1985In the upper part of the plate, an interlobular artery (1) is depicted with an afferent (2) and efferent (3) arteriole. A nephron, the parts of which arerenal corpuscle (4), proximal tubule (5), thin segment (6), distal tubule (7), and connecting portion (8)—is joined to a collecting tubule (9), which is lined with simple columnar epithelium (10).
