| The purpose of this study was to determine the anatomic parameters of the kidney in adults. The Renal lengths, width at superior and inferior poles, thickness at the superior and inferior poles were measured in 151 adult cadaver kidneys. A digital vernier caliper was used for performing the measurements. The data were statistically analyzed. The mean renal length was 8.9 ± 0.9 cm on the right side and 9.1 ± 0.9 cm on the left side. The mean width of the superior pole of the right kidney was 4.9 ± 0.6 cm and the left kidney was 5 ± 0.7 cm. The width of inferior pole of the right and left kidneys were 4.8 ± 0.6 cm and 4.5 ± 0.7 cm respectively. The mean thickness of the superior pole of the right kidney was 3 ± 0.4 cm and left kidney was 3.2 ± 0.5 cm. The... |

| Lead is one of the heavy metals most used in industry. Poisoning due to long-term lead exposure is known as saturnism, and is an occupational illness that has been known for many years. Lead is highly toxic and can compromise the structural and functional patterns of organs and systems. The aim of this study was to examine the lungs and kidneys of fetuses from female Wistar rats exposed to lead acetate. In this study, the lungs and kidneys of 20 fetuses from female rats that had previously been treated with lead acetate were dissected, fixed, embedded in paraffin and stained with hematoxylin and eosin. Macroscopic changes to the shape, color and consistency of organs from fetuses treated with this heavy metal were observed, in comparison with organs from... |

| Advanced imaging techniques have resulted in increasing use of minimally invasive approaches for nephron sparing surgeries of kidney. Need for precise knowledge of normal and variant anatomy of vascular pedicle of kidney is thus justified. Ample literature is available on the variations in the intrarenal vascular pattern of the kidney, which are seen frequently. But the variation in arrangement of structures at the renal hilum has not gained much interest up till now. One hundred (51 right and 49 left) embalmed kidneys were utilized for the present study. Careful dissection of renal hilar structures was carried out to observe antero-posterior relationship of structures at the hilum of the kidney. In majority (73%), the arrangement was not according to the... |

| The possibility of characterizing the proximal convoluted tubuli of the dog kidney by means of a unique and objective value, is an attractive idea in order to automate its recognition in anatomy and patology. For this, we obtained a fractal dimension of the proximal convoluted tubuli in the dog kidney by mean box-counting method. The fractal value we obtained is a flat dimension, and it is different than the line fractal dimension of the dog kidney arterial pattern, which was previously calculated by us (Gil et al., 2006). Thus, from optical microscopy images, we are able to obtain a single quantitative measure to discriminate these dog kidney components. This measures can use to automate its recognition. Fractal geometry provides many advantages when... |

| The objective of this study was the evaluation of aspartame effects on morphometric alterations of the glomerulus, proximal and distal convoluted tubules and collecting ducts of the rat fetal kidney during organogénesis. Fifteen pregnant rats averaging 24 g body weight, were divided into 3 groups (n=5 each) of controls, rats treated with aspartame exposed to room temperature and rats treated with aspartame heated to 40°C. Animals were given 14mg / kg aspartame by the intragastric route on the 9th, 10th, and 11th days of pregnancy. Karyometric and stereological techniques estimated morphological changes. A significant decrease of fetal body weight was observed in the group given aspartame kept at room temperature, compared to controls. Karyometry permitted... |

| Physical effort stimulates an increase in oxygen consumption in tissues, generating toxic chemical species derived from oxygen (ROS), which are considered the initiators of the lipid peroxidation process (LPO), the major mechanism of cellular injury. As the essential mechanism for maintaining the electrolyte balance depends on an effective kidney function, oxidative stress in this organ can be a key factor in the development and persistence of hypertension. This study aimed to determine the kidney changes induced by a combination of fluid restriction and exercise in rats. The study consisted of 24 male Wistar rats of 90 days of age, divided into four groups, two of which were submitted to water restriction and exercise on a treadmill.Twenty-four hours... |

| The gonadal arteries (testicular or ovarian arteries) emerge normally from the lateral aspect of the abdominal aorta, a little inferior to the renal arteries. Several other sites of origin of these arteries have been recorded with the renal and accessory renal arteries being the most common. In the present case report, the testicular arteries originated from the lower polar accessory renal arteries in both sides. The testicular veins followed had the usual origin and course, while an accessory renal vein was observed only in the right side. These anomalies were combined with an abnormal left ureter exiting from the lower pole of the kidney. Only one male cadaver among 77 adult human cadavers of Caucasian origin presented this set of variations (frequency:... |

| The anti-inflammatory effect of dexamethasone on the irradiated kidneys of adult Wistar rats (Rattus norvegicus) was studied. Eighteen adult Wistar rats were, after acclimatization, randomly divided into 3 groups of 6 animals per group. The control group had normal saline, receiving neither drugs nor radiation. The second group received normal saline and radiation. The third group received pretreatment with dexamethasone at 1mg/kg body weight/day for 2 days followed by radiation. Radiation was delivered to the animals as a single fraction of 2.5 Gy of gamma rays from Cobalt-60 source, using an AECL Theatron 780-C Teletherapy machine. After exposure to the different interventions, the animals were sacrificed on the 14th post-irradiation day and the kidneys... |

| Irrigation of the kidneys is usually provided by a single renal artery; however, variations on this pattern have frequently been reported. This study was aimed at establishing the renal arteries' frequency and morphological characteristics in cadaverous material taken from a half-caste population from Bucaramanga (Colombia). The sample included 195 renal blocks corresponding to 57 (14.6%) kidneys from females and 333 (85.4%) from males. The renal arteries were injected with synthetic resin (palatal GP41L); following the resin's polymerization, the renal blocks were placed in KOH solution for corrosion the renal parenchyma. The individuals from whom the renal blocks, 74.9% of the kidneys presented renal arteries single and 25.1% had additional renal... |

| Silver nanoprticles (SNPs) are invested in medical, industrial and environmental applications. Little if any, is known about the morphometric alterations induced by the toxicity of SNPs. The aim of the present work is to find out the effect of variable size of SNPs on different morphometric parameters. Adult healthy male mice (BAL/C) were subjected to (10 nm, 20 nm, 40 nm 60 nm and 100 nm) SNPs for 35 days. Silver NPs caused non-significant decline on the average weight, significant decline in food consumption, increase in water intake, unilateral blindness, tanning fur color and cholestasis together with a decrease in the relative ratio of the liver, kidney and spleen weight to body weight. Mice subjected to 10 nm and 20 nm were more affected than mice... |

| In this study, we evaluated the ultrastructural findings of kidney with systemic administration of different doses of atorvastatin in a rat model. Statins may have anti-inflammatory effects that would play a role in preventing the cellular damage. The aim of this study was to investigate how atorvastatin could play a role in kidney tissues. Forty adult male Wistar albino rats (200250 g) were randomly divided into 4 groups of ten rats each (A1, A2, A3 and Control). Three different doses of atorvastatin were used to determine the effects on kidney tissues during 90 day period. The kidneys of A1 (0.1-mg group), A2 (0.5-mg group) and A3 (1-mg group) group were excised and the tissues were examined after the 90 days by transmission electron microscopy. Despite... |
