Only the Plethodontidae lack a renal corpuscle (character 7, state 1) separating the vasa efferentia from the more distal epididymal ducts Too little data are available to recover ancestral state for salamanders in terms of Wolffian ducts without ciliated cells (character 8, state 0) or Wolffian ducts with ciliated cells (character 8, state 1) The branches leading to the Ambystomatidae + Dicamptodontidae + Salamandridae and Rhyacotritonidae possess Wolffian ducts with ciliated epithelial cells, whereas the branches leading to the Plethodontidee and Proteidae do not possess ciliated Wolffian ducts.
The afferent epididymal ducts empty into a renal corpuscle and, thus, are delineated grossly from the efferent epididymal ducts by a renal corpuscle in all salamanders except the Eurycinae (Williams et al., 1984), Rhyacotritonidae, and Sirenidae.
Morphometric investigations of the animals from this group (test 5) showed that the number of renal corpuscles per field is 17.65% (P[less than or equal to]0.05) decreased; the size of renal corpuscle is 36.72% (P[less than or equal to] 0.05) increased; the size of renal glomerulus is 29.92 % (P[less than or equal to]0.05) increased comparing to the control.
While consuming tapwater with high content of ions of ferrum, calcium, magnesium and fluorine the most significant changes are observed in kidneys of the pregnant animals which is expressed in the decreasing of the number of renal corpuscles and their inhomogeneity; increasing of the average size of renal corpuscle and glomerulus.
The liver is known to According to the present study injection with cisplatin (5 mg/kg b.w.) induced depletion in the polysaccharides contents of the liver cells and the renal corpuscles and tubules.
In the cortex we found groups of tubules radially arranged which consisted of collector tubules and straight portions of nephrons forming pars radiata and other groups of twisted tubules consisting of renal corpuscles and numerous proximal and distal convoluted tubules forming the twisted pars.
Histological analysis of kidneys of CRE group showed: cortical area with the presence of indefinite renal corpuscles and difficult delimitation of the Bowman's capsule, congestion of glomeruli capillary, and intra-capsular and tubular spaces not preserved, which indicated tissue damage (Figure 4B).
Internally, two regions are distinguished in the renal parenchyma: the cortex (out region) and the medulla (inner region), with innumerable tubules and renal corpuscles (nephrons).
On histological examination, the sagittal section of kidneys from the control group showed well developed cortical renal corpuscles; these contained loops of glomerular capillaries, surrounded by Bowman's capsule, having visceral and parietal layers, with capsular space in between.
Measurement of diameter periglomerular thickness and diameter of renal corpuscles was made after calibrating eyepiece graticule with stage micrometer at various magnifications using x10 and x40 objectives.
