The major component, called curcumin, of turmeric (Curcuma longa L.) (Family Zingiberaceae) powder is responsible for its biological actions. The present study aimed to prove the protective effect of turmeric extract against doxorubicin (DOX)-induced cardiac, hepatic, and renal toxicity as evaluated in rats. Body weight and urine volume of the animal groups under investigation were recorded daily throughout the experimental period. Also, the cardiac, hepatic, and renal toxicities were determined by estimating the changes in serum activities of the enzymes lactate dehydrogenase (LDH) and creatine kinase (CK), serum levels of alanine aminotransferase, aspartate aminotransferase, nitric oxide, albumin, and calcium, and kidney and liver tissue activities of superoxide dismutase and glutathione peroxidase, as well as the contents of glutathione and malondialdehyde. Hyperlipidemia was also determined, and protein and albumin changes in urine were estimated. Biochemical and histopathological findings demonstrate that turmeric extract has multiple therapeutic activities that are beneficially protective, and it has an ameliorative effect against DOX-induced cardiac toxicity and hepatotoxicity and blocks DOX-induced nephrosis. Similarly, turmeric extract inhibited the DOX-induced increase in plasma cholesterol, LDH, and CK. The present findings conclude that the turmeric extract has multiple therapeutic activities that block the cardiac, hepatic, and renal toxicities induced by DOX, and it also possibly acts as a free radical scavenger.

Cholemic nephrosis represents a spectrum of renal injury from proximal tubulopathy to intrarenal bile cast formation found in patients with severe liver dysfunction. However, the contribution of this diagnosis has been largely forgotten in the modern literature. To more precisely define this, we conducted a clinicopathologic study of 44 subjects (41 autopsies and 3 renal biopsies) from jaundiced patients at the University of Chicago. Of these, 24 patients had bile casts with involvement of distal nephron segments in 18 mild cases and extension to proximal tubules for 6 severe cases. Eleven of 13 patients with hepatorenal syndrome and all 10 with cirrhosis (due to alcoholism) had tubular bile casts. These casts significantly correlated with higher serum total and direct bilirubin levels, and a trend toward higher serum creatinine, AST, and ALT levels. Bile casts may contribute to the kidney injury of severely jaundiced patients by direct bile and bilirubin toxicity, and tubular obstruction. Both mechanisms are analogous to the injury by myeloma or myoglobin casts. Accounting for the presence of renal bile casts provides a more complete representation of the renal injury that can occur in this unique clinical setting. Thus, bile cast nephropathy is an appropriate term for the severe form of injury observed in the spectrum of cholemic nephrosis. Additional studies are needed to establish the significance of this parameter for patient management in different clinical settings.

Although acute hepatitis and nephrotic syndrome are commonly reported as complications of tertiary syphilis, nephrotic syndrome concomitant with hepatitis in early-stage syphilis is rare. Here, we describe the case of a 46-year-old male who was diagnosed with acute liver dysfunction and nephrotic syndrome after presenting with general malaise, and who subsequently developed acute kidney injury. Laboratory examination showed alkaline phosphatase had a greater magnitude of elevation compared to alanine aminotransferase, suggesting the possibility of syphilitic hepatitis. The rapid plasmin regain test and Treponema pallidum hemagglutination assay were positive, supporting the presence of a syphilis infection. Additionally, liver biopsy examination showed infiltration of inflammatory cells into the portal area and epithelioid cell granulomas. Moreover, kidney biopsy examination by both optical and electron microscopy showed a congestion of neutrophils in the capillary vessels, structural collapse of the tubules, and subepithelial deposits under the epithelium of the glomerular endothelial cells. These pathological changes were consistent with those reported previously for early syphilitic hepatitis and nephrotic syndrome in early-stage syphilis. All the symptoms, including liver and renal dysfunction, resolved after benzyl penicillin treatment was initiated. Hence, we believe early-stage syphilis should be included in the differential diagnosis of unknown liver damage and/or nephrosis.

A striped dolphin (Stenella coeruleoalba) calf stranded alive because of a Salter-Harris fracture type 1 of a caudal vertebra and remained in a provisional rehabilitation facility for 3 days where the fracture stabilization was attempted, but he died the day after bandaging. Serum and urine samples were collected during hospitalization (days 1, 2 and 3 serum and day 2 urine). Serum analysis showed increased urea, alanine transaminase, aspartate transaminase, and serum amyloid A values, while creatinine was below the lower limit. Urine analysis showed urinary protein-to-creatinine ratio of 5.3 with glomerular proteinuria. Postmortem analyses demonstrated a severe rhabdomyolysis and myoglobinuric nephrosis, suggestive of capture myopathy syndrome. We report, for the first time, the clinico-pathological changes during this condition in a striped dolphin.

Artemisinin is a powerful antimalarial drug, useful in the treatment of many diseases, including chickens coccidiosis. Its toxic effects have been well studied in humans and experimental animals, but not sufficiently in broiler chickens. Therefore, in the present study, we aimed to assess the side effects of artemisinin in chickens, by measuring the serum level of proteins and enzymes (ALT, AST, GGT, ALP, CK), by histopathological examination and by the evaluation of relative weight of organs (liver, kidney, heart). Artemisinin was administered in the standard feed for chickens in three different concentrations: 5, 50 and 500 ppm. Each concentration of artemisinin increased the total serum proteins, gamma-globulins and the serum activity of CK and decreased the serum ALP level. The values of ALT and GGT were higher in the chickens treated with 50 and 500 ppm of artemisinin. Multifocal liver necrosis and inflammatory infiltrate were detected in the chickens that received the 50 and 500 ppm dosage of artemisinin. Minimal tubular necrosis, renal tubular epithelium vacuolation, multifocal interstitial nephritis and mild uric nephrosis were detected in chickens treated with the drug. Artemisinin administration produced no significant changes in the organs relative weight. Artemisinin, at a concentration of 5 mg/kg of feed is well tolerated by broiler chickens, but the concentrations of 50 and 500 mg/ kg feed can produce toxic effects.
