| ABSTRACT We analyzed the presence of Leptospira spp. in liver and kidney tissue of wild marsupials and rodents trapped in a periurban forest in the eastern Brazilian Amazon. We examined 25 individuals of four marsupial and seven rodent species for the presence of the 16S rRNA gene of Leptospira in the DNA extracted from 47 liver and kidney tissue samples using PCR. We detected positive samples in 12% (3/25) of the individuals, in kidney fragments of two marsupial species (Didelphis marsupialis and Marmosops pinheiroi) and in a liver fragment of one rodent species (Echimys chrysurus). These are the first records of Leptospira spp. in M. pinheiroi and E. chrysurus and it is the first molecular survey of marsupials and rodents in the Brazilian Amazon. |

| Kidneys are especially irrigated by a pair of arteries originated from the aorta artery. The presence of additional renal arteries is the most frequent variation in this vascularization, an aspect important to be known in renal surgeries and radiological procedures (SAMPAIO; PASSOS, 1992). This study aimed to observe the prevalence of numeric variation and the origin of the additional renal artery. For this purpose, 24 cadavers and 26 blocks were used; each block contained the kidneys and their respective arteries and veins, the abdominal aorta and inferior vena cava, taken from adults of different ethnicity and genders, from the Department of Morphological Science, State University of Maringá (DCM/UEM) and Laboratory of Anatomy, Ingá Faculty (UNINGÁ).... |

| The cystic fibrosis transmembrane regulator (CFTR) is a Cl- channel. Mutations of this transporter lead to a defect of chloride secretion by epithelial cells causing the Cystic Fibrosis disease (CF). In spite of the high expression of CFTR in the kidney, patients with CF do not show major renal dysfunction, but it is known that both the urinary excretion of drugs and the renal capacity to concentrate and dilute urine is deficient. CFTR mRNA is expressed in all nephron segments and its protein is involved with chloride secretion in the distal tubule, and the principal cells of the cortical (CCD) and medullary (IMCD) collecting ducts. Several studies have demonstrated that CFTR does not only transport Cl- but also secretes ATP and, thus, controls other... |

| Abstract: To date, most of studies have only focused on metabolic effects of dietary oils while recent evidence proposes that they can influence kidneys structure. Therefore, the aim of this study was to evaluate the impact of long-term consumption of olive, cottonseed and sesame oils on renal morphology in rats. 70 male Wistar rats randomly assigned into seven equal groups and treated with standard diet (control), the standard diet enriched with 10% or 20% (W/W) of either olive oil (OLI10%, OLI20%), cottonseed oil (COT10%, COT20%) or sesame oil (SES10%, SES20%) for 5 months. Quantitative features of the kidney including kidney and cortex volumes and the number of glomeruli were analyzed stereologically. Moreover, kidney sections histologically were... |

| ABSTRACT Scorpions belonging to the Tityus genus are of medical interest in Brazil. Among them, Tityus stigmurus is the main scorpion responsible for stings in the Northeast region. After a sting, the scorpion venom distributes rapidly to the organs, reaching the kidneys quickly. However, there are few studies concerning the renal pathophysiology of scorpion poisoning. In this study, we evaluated the effects of T. stigmurus venom (TsV) on renal parameters in isolated rat kidneys. Wistar rats (n = 6), weighing 250-300 g, were perfused with Krebs-Henseleit solution containing 6 g/100 mL bovine serum albumin. TsV at 0.3 and 1.0 μg/mL was tested, and the effects on perfusion pressure (PP), renal vascular resistance (RVR), urinary flow (UF), glomerular... |

| O trematodeo digenético Paratanaisia bragai é descrito como parasito dos túbulos coletores renais e ureteres de aves. Esse helminto é usualmente pouco patogênico para a maioria dos hospedeiros; porém, em altas cargas parasitárias e em animais mais suscetíveis, pode causar sérios danos que resultam em apatia, perda de peso, desidratação e até mesmo a morte. O presente trabalho objetivou relatar pela primeira vez o trematoide P. bragai parasitando os rins de um passeriforme da espécie Estrilda astrild, conhecido popularmente como bico-de-lacre, de distribuição cosmopolita. A partir da análise histopatológica dos rins da ave, observou-se a presença dos vermes adultos e de ovos, grande dilatação dos ductos coletores renais, destruição e achatamento das células... |

| Calotropis species have been used in the traditional medicinal system for the treatment of diseases of the liver and abdomen. In view of the antioxidant and anti-hyperglycemic properties of an aqueous suspension obtained from the dried latex of Calotropis procera, the present study was carried out to evaluate its efficacy in affording protection against alloxan induced changes in rat kidney. A single intraperitoneal injection of alloxan (150 mg/kg) in rats produced hyperglycemia within 3 days and altered kidney functions over a period of 90 days. Daily oral administration of the aqueous suspension (100 and 400 mg/kg) in diabetic rats produced anti-hyperglycemic effect that was comparable to that of glibenclamide (10 mg/kg). Unlike glibenclamide, the... |

| Objective: To investigate the course of tubular cell senescence and expressions of p53, p21, and Rb during the late phase of ischemia/reperfusion (IRI) in the kidney, and assess the effects of the p53-Rb pathway on tubular cell senescence. Methods: Experimental models of unilateral renal IRI were used in p53(+/+) and p53(-/-) mice. Histological changes at the tubular level, progress of cell senescence, and the expression of Rb, p21, and/or p53 proteins in tubular cells were studied at different moments in time after IRI. Results: Chronic tubulointerstitial fibrosis was much more severe and widely distributed in IRI kidneys of p53(+/+) mice in later stages than in earlier stages. Senescent tubular cells were significantly increased at 3 and 6 months after... |

| Abstract Background A number of dysregulated miRNAs have been identified and are proposed to have significant roles in the pathogenesis of type 2 diabetes mellitus or renal pathology. Alpinia oxyphylla has shown significant anti-inflammatory properties and play an anti-diabetes role. The objective of this study was to detect the alteration of miRNAs underlying the anti-diabetes effects of A. oxyphylla extract (AOE) in a type II diabetic animal model (C57BIKsj db-/db-). Results Treatment with AOE for 8 weeks led to lower concentrations of blood glucose, urine albumin, and urine creatinine. 17 and 13 miRNAs were statistically identified as differentially regulated in the DB/DB and db-/db- AOE mice, respectively, compared to the untreated db-/db- mice. Of... |

| Matrix metalloproteinases (MMPs) comprise a large group of endoproteinases that degrade all protein components of the extracellular matrix. Functionally, MMPs contribute to several different physiological as well as pathological conditions. The number of newly described MMPs has increased in recent years, although current knowledge about their expression pattern in various tissues remains incomplete. Here we analyzed the relative mRNA expression of the most recently described MMPs _ MT5-MMP (MMP-24), MT6-MMP (MMP-25), MMP-27 and epilysin (MMP-28) _ in a broad selection of rat tissues using real time-PCR. MMP-24 mRNA was found to be widely expressed with predominance in the central nervous system. MMP-25 mRNA, in contrast, exhibited peak expression levels... |

| Studies were carried out to analyse the kidney histopathological alterations of "curimbatá", Prochilodus lineatus, were analyzed. An acute bioassay was made by the water contamination with 0.2muml/l of Dipterex 500 (Trichlorfon). The kidney tissue collected after 24 hours of exposure showed an enlargement of intercapsular space with glomerular atrophy, hypertrophy of the kidney tube cells, with small granules on its cytoplasm and little nuclear alteration. Blood overflowing from capillaries with pyknotic nuclei and vacuoles in the cytoplasm it was also noticed. After 48 hours, the kidney tissue showed glomerular expansion, impossibility to visualize the intercapsular space as well as cytoplasm limit of many cells. The parietal capsular epithelium and the... |

| This study assessed the bioactive properties of an aqueous extract of M. officinalis for its anti-inflammatory activity and its protection against hepatic and renal lesions induced by acetaminophen (APAP). Animals pre-treated with the crude extract in pleurisy induced by carrageenan showed a reduction in the amounts of exudate, in the numbers of leukocytes and polymorphonuclear cells. Intragastric administration of the extract for seven days prior to the APAP-induced lesion showed no protective effect on the liver. The treatment with the extract induced an increase of serum aspartate aminotransferase, indicating a rise of toxicity. Contrarily, the same treatment reduced the APAP induced lesion in kidney, with respect to ν-glutamyltransferase. The results... |

| Furan is a food and environmental contaminant and a potent carcinogen in animals. Lycopene is one dietary carotenoid found in fruits such as tomato, watermelon and grapefruit. The present study was designed to explore the protective effect of lycopene against furan-induced oxidative damage in streptozotocin (STZ)-induced diabetic rat kidney. At the end of the experimental period (28 days), we found that lycopene markedly decreased the malondialdehide (MDA) levels in the kidney, urea, uric acid and creatinine levels in the serum of furan-treated rats. The increase of histopathology in the kidney of furan-treated rats were effectively suppressed by lycopene. Furthermore, lycopene markedly restored superoxide dismutase (SOD), catalase (CAT), glutathione... |

| The aim of this study was to compare the effect of fluoride (F) on alkaline phosphatase activity in the liver and plasma of the rats. Four groups of male Wistar rats (n=6), which received drinking water containing 5, 15 or 50 ppm F or deionized water (control) throughout the experiment were included in the study. The animals were euthanized and had their tissues and blood plasma collected for the analysis of fluoride and alkaline phosphatase. There was an increase in F concentration in most tissues in the animals treated with higher F concentrations, except for the heart. The alkaline phosphatase assay showed an increase in the activity in the liver and blood plasma of the animals treated with fluoride concentrations of 15 and 50 ppm (p<0.05). This... |
