Abstract
Due to an increasing demand for testing of new and existing chemicals and legal restrictions for the use of animals, there is a strong need for alternative approaches to assess systemic toxicity. Embryonic and larval zebrafish (Danio rerio) are increasingly recognized as a promising alternative whole-animal model that may be able to overcome limitations of cell-based in vitro assays and bridge the gap between high-throughput in vitro screening and low-throughput in vivo tests in animals. Despite the relatively simple anatomical structure of the zebrafish larval kidney (pronephros) - composed of only two nephrons - the pronephros shares major functions and cell types with mammalian nephrons. Glomerular filtration begins at 48 h post fertilization. The aim of the present study was to investigate if early zebrafish larvae might be a suitable model for nephrotoxicity testing. On day 3 post fertilization, larval zebrafish were treated with selected nephrotoxins (aristolochic acid, cadmium chloride, potassium bromate, ochratoxin A, gentamicin) for 48 h. Histological evaluation of zebrafish larvae exposed to model nephrotoxins revealed tubule injury as evidenced by dilated tubules with loss of the brush border, tubule cell necrosis and disorganization of the tubular epithelium. These changes were most severe after treatment with gentamicin, which also impaired pronephros function as evidenced by reduced clearance of FITC-dextran. Whole-mount in situ hybridization showing loss of cdh17 expression revealed site-specific injury to the proximal tubule segment. Analysis of genes previously identified as novel biomarkers of kidney injury in mammals showed upregulation of the kidney injury marker genes heme oxygenase 1 (hmox1), clusterin (clu), secreted phosphoprotein/osteopontin (spp1), connective tissue growth factor (ctgf) and kim-1 (havcr-1) in response to nephrotoxin treatment, although the response of individual genes varied across compounds. Consistent with the severity of lesions and impaired kidney function, the most prominent gene expression changes occurred in larvae exposed to gentamicin. Overall, our results suggest that larval zebrafish may be a suitable alternative model organism for nephrotoxicity screening, yet further improvements and integration with quantitative in vitro to in vivo extrapolation will be needed to predict human toxicity.

Abstract
Male Wistar rats were randomly divided into three groups--A, B and C. A dose of 5 mg and 10 mg of cadmium chloride/kg body weight/day was orally administered to groups B and C, respectively. Rats from group A served as control. Rats were sacrificed on 1st, 2nd, 4th, 6th, and 8th week after initiation of the experiment. Kidneys were removed immediately, fixed in Bouin's fixative, routinely processed and stained with hematoxylin and eosin. The present study showed that the histopathological changes were caused in kidney of rats by cadmium exposure. The changes noticed were mainly--the glomerular swelling (at initial stage), the shrinkage of glomerulus (at later stage), the tubular dilatation, hypertrophy of tubular epithelium, degeneration of glomerulus and renal tubules and deposition of eosin-positive substances in the glomerulus and renal tubules. However, lesions were depended upon the doses and duration of the treatment.

Abstract
Cell adhesion molecules are integral cell-membrane proteins that maintain cell-cell and cell-substrate adhesion and in some cases act as regulators of intracellular signaling cascades. In the kidney, cell adhesion molecules, such as the cadherins, the catenins, the zonula occludens protein-1 (ZO-1), occludin and the claudins are essential for maintaining the epithelial polarity and barrier integrity that are necessary for the normal absorption/excretion of fluid and solutes. A growing volume of evidence indicates that these cell adhesion molecules are important early targets for a variety of nephrotoxic substances including metals, drugs, and venom components. In addition, it is now widely appreciated that molecules, such as intracellular adhesion molecule-1 (ICAM-1), integrins, and selectins play important roles in the recruitment of leukocytes and inflammatory responses that are associated with nephrotoxic injury. This review summarizes the results of recent in vitro and in vivo studies indicating that these cell adhesion molecules may be primary molecular targets in many types of chemically-induced renal injury. Some of the specific agents that are discussed include cadmium (Cd), mercury (Hg), bismuth (Bi), cisplatin, aminoglycoside antibiotics, S-(1,2-dichlorovinyl)-l-cysteine (DCVC), and various venom toxins. This review also includes a discussion of the various mechanisms, by which these substances can affect cell adhesion molecules in the kidney.

Abstract
Pathomorphological investigations of internal organs were made in sheep given sublethal doses of cadmium. Early histological damages in kidneys were established by renal biopsy in some experimental animals. The main histological changes were characterized by granular degeneration in proximal tubules and glomerular endothelial proliferation in kidneys, granular degeneration in hepatocytes, pericapillary oedema and activation of capillary endothelium and Kupffer cells in liver, oedematous and degenerative changes in cerebrum and in the region of Purkinje cells of cerebellum, hyperplasia and proliferation of alveolar epithelium and perivascular or peribronchial mononuclear cell infiltration in lung, and degenerative changes in the medulla and zona glomerulosa of adrenal glands.

Abstract
The Greenland marine food chains contain high levels of cadmium, mercury and selenium. Concentrations of cadmium in the kidney of ringed seals (Phoca hispida) from the municipalities of Qaanaaq and Upernavik (Northwest Greenland) are among the highest recorded in the Arctic. The purpose of the study was to determine whether cadmium-induced damage in the kidneys and the skeletal system could be detected among 100 ringed seals from Northwest Greenland. The cadmium concentrations in the kidney cortex ranged from 0 to 248 microg/g wet weight (mean=44.5, N=100) in the 99 kidneys examined. Experience from cadmium-poisoned humans and laboratory mammals indicates that concentrations above 50-200 microg/g wet wt. may induce histopathological changes. Overall, 31 of the ringed seals had cadmium concentrations in the kidney cortex above 50 microg/g wet wt., 11 had concentrations above 100 and one had a concentration above 200 microg/g wet wt. Obvious histopathological changes (categorised mainly as glomerulonephritis) were found in 10 of the seals; however, none of these changes could be attributed to cadmium-induced renal damage (mainly tubulopathy) as described for other species. Damage to the proximal kidney tubules is known to induce demineralisation of the skeletal system (Fanconi's syndrome). Therefore, the three lowest lumbar vertebrae were scanned in 91 seals to measure the content of calcium. The 10 cases of nephropathy could neither be linked to the degree of mineralisation of the skeleton nor to the cadmium concentrations. Furthermore, the degree of mineralisation of the skeleton was not correlated with the cadmium concentration, age or sex. It can therefore be concluded that despite high levels of cadmium, none of the ringed seals showed any signs of cadmium-induced nephropathy or osteodystrophy. This might be explained by the composition of the ringed seals diet, which contains high levels of vitamin D, calcium, phosphorus, zinc, selenium and protein. These elements are all likely to counteract cadmium-induced damage. It is speculated that ringed seal are not particularly vulnerable to osteodystrophy, due to their continuous growth (bone mineralisation) throughout life and the oestrogen hormonal activity of females throughout life.

Abstract
To evaluate the effect of cadmium intoxication on renal transport systems for organic anions and cations, transport of p-aminohippurate (PAH) and tetraethylammonium (TEA) were studied in renal cortical plasma membrane vesicles isolated from cadmium-intoxicated rats. Cadmium intoxication was induced by daily injections of CdCl2 (2 mg Cd/kg.day sc) for 2-3 weeks. Renal plasma membrane vesicles were prepared by Percoll gradient centrifugation and magnesium precipitation method. Vesicular uptake of substrate was determined by rapid filtration technique using Millipore filter. The cadmium treatment resulted in a marked attenuation of Na(+)-dependent, alpha-ketoglutarate (alpha KG)-driven PAH uptake in the basolateral membrane vesicle (BLMV), and this was due to a reduction in Vmax and not K(m). The Na(+)-alpha KG symport activity of the BLMV was not affected by 2-week cadmium treatment, but it was significantly inhibited by 3-week cadmium treatment. On the other hand, the alpha KG-PAH antiport activity of the BLMV appeared to be markedly suppressed in 2-week as well as 3-week cadmium-treated animals. The cadmium treatment inhibited the proton gradient-dependent TEA transport in the brush-border membrane vesicle (BBMV), and this was associated with a reduction in Vmax with no change in K(m). These results indicate that cadmium exposures may impair the capacities for organic anion transport in the proximal tubular basolateral membrane and organic cation transport in the luminal membrane. The cadmium effect on organic anion transport is attributed mainly to an inhibition of dicarboxylate-organic anion antiport system.

Abstract
Cadmium toxicity to the cornea of pregnant rats was studied using the electron microscope and x-ray microanalyzer. In in-vivo experiments, severe corneal edema occurred in pregnant dams that received intraperitoneal injections of cadmium sulphate for 4 days during gestation, but not in nonpregnant rats. Prominent swelling of mitochondria and the occurrence of intra- and intercellular vacuoles in the corneal endothelium were observed only in pregnant dams. In in-vitro experiments, electron-dense deposits consisting of cadmium-oxine complexes were preferentially found in swollen mitochondria of the endothelial cells. Cadmium peaks were obtained from these deposits with x-ray microanalysis. These data suggest that the corneal edema observed after administration of cadmium may imply the disturbance of pump function and barrier function of the corneal endothelium due to the primary toxic effects of this metal on mitochondria.

Abstract
Changes in renal function, Na+-K+-ATPase activity and PAH transport system in kidney cortex were studied in rats treated with cadmium. Subcutaneous injections of CdCl2 (2 mg Cd/kg.day) for 16 days induced a marked polyuria and a hyposthenuria. These changes were accompanied by increase in urinary protein, glucose, urea, calcium, phosphate, chloride and potassium excretions. The change in urine flow was proportional to the change in total osmotic solute excretion. Creatinine excretion and TcH2O remained unchanged. Na+ excretion was not increased, but the Na+-K+-ATPase of renal cortex was significantly inhibited. PAH uptake by renal cortical slices was markedly attenuated in Cd-treated rats. The Vmax for active PAH influx was drastically reduced, but the Km was not changed. The passive influx and efflux of PAH across the basolateral membrane and the renal tissue oxygen consumption were not apparently altered in Cd-treated animals. These results indicate that 1) the nature of Cd-induced polyuria and hyposthenuria is an osmotic diuresis induced by proximal tubular rejection of various substances, and 2) the mechanism of impaired renal PAH excretion in Cd-treated animals is a loss of organic anion carriers in proximal tubular basolateral membranes.

Abstract
Histological, ultrastructural and kidney function techniques were used to assess changes in the kidney of sheep given either copper (Cu) or Cu and the Cu complexing agent thiomolybdate (TM), or TM alone. Kidney function was normal in sheep given Cu and TM together or TM alone. In these animals the cells lining cortical tubules accumulated Cu within numerous, large, electron-dense lysosomes. Sheep given Cu alone developed haemolysis, impaired kidney function and a variety of morphological defects including an increase in number of large lysosomes in cells of the cortical tubules. There was a breakdown of the glomerular endothelial lining and fusion of foot processes. Cells of the cortical tubules showed degeneration and necrosis and an increase in microbodies and rough endoplasmic reticulum. Cortical and medullary blood vessels were dilated, with evidence of breakdown of the endothelial lining. Copper appeared to injure kidney tissue at three sites, tubular epithelium, glomerular basal lamina and capillary blood vessels. Changes reported here are similar to the renal lesions in cadmium toxicity.

Abstract
Sensitivity of tissues to the acute toxicity of cadmium is reviewed. It is concluded that the initial effect of acute cadmium administration is on the integrity and permeability of the vascular endothelium; other necrotic changes occur secondarily to this effect. In a sensitive tissue, not all of the endothelial cells are susceptible to cadmium. Furthermore, after necrosis of the sensitive cells, the resistant cells proliferate and result in regeneration of the vasculature and subsequent acquired resistance to the metal. It is found that sex hormones are probably important in determining susceptibility and response of tissues to cadmium. The role of metallothionein in these phenomena remains to be elucidated.
