in order to study the role of the kidney in fish osmoregulation, freshwater acclimatized juvenile spottedscat (scatophagus argus l.) were subjected to four different salinities and observed for histomorphometricchanges of the kidney at 1, 2, 10 and 15 days post transfer time points. the overall morphological changesdisplayed by fish kidney included significant decrease in the density of collect...

A supernumerary kidney is defined as a true accessory organ with a collector system, blood circulation and independent encapsulated tissue. In contrast with the horseshoe kidney, this congenital abnormality is extremely rare.1 Kidneydevelopment begins in 2 structures during thefifthweek of gestation: the distal portion of the wolffian duct in which the collector tubules originate, and the renal...

OBJECTIVE Carthamus tinctorius L. (C. tinctorius) is used as a food additive but also has medicinal applications. The present work was designed to investigate its probable side effects on the histology and function of the kidney in the mice. MATERIALS AND METHODS Sixty adult Balb/C mice were randomly distributed into one control and three experimental groups. The control group received only d...

The aim of the present study was to evaluate the effect of a hydro-alcoholic extract of Vitex agnus-castus (VAC) fruit on blood urea nitrogen (BUN), creatinine (Cr) and, kidney histology of a female mouse model of D-galactose induced aging. In this experimental study, 72 NMRI mice were divided into 6 groups: control, VAC, D-galactose, D-galactose+VAC, aging, and aging+VAC. D-galactose was injec...

Myxozoans are common parasites of fish kidneys, with most having specific sites of development. Five specific sites of development include (1) the lumen of renal tubules, (2) the renal corpuscles followed by location in renal tubules, (3) intracellular location within the tubular epithelium followed by a stage in the lumen of the ducts, (4) haematopoietic tissue with dispersed trophozoites, and...

Palaeonitella trifurcata n. sp. is a minute ecorticate thallus of charophyte from non-marine upper Barremian–Lower Aptian section the Garraf Massif, near Barcelona (Catalonia, Spain). Whorls trifurcated branchlets built glomerules about 1 mm across. Small radial were once in three terminal acuminate dactyls. Longer and more robust branches, two per whorl emerge basal trifurcation, bore opposite...

Objective: Carthamus tinctorius L.(C. tinctorius) is used as a food additive but also has medicinal applications. The present work was designed to investigate its probable side effects on the histology and function of the kidney in the mice. Materials and Methods: Sixty adult Balb/C mice were randomly distributed into one control and three experimental groups. The control group received only di...

In order to study of kidney tubules, twenty specimen of 45 days old juvenile grouper (Epinephelus coioides) were prepared after proper biometry. Five mm thick sections were removed from the middle and posterior end of the kidney and fixed in Bouin and glutaraldehyde. The routine procedures of preparation of tissues were followed for light and transmission electron microscopic study. In macrosco...
