  • Congenital thoracic ectopic kidney is a very rare developmental disorder and the rarest type of ectopic kidney. This condition is usually asymptomatic and detected incidentally on routine chest radiography. Most cases of thoracic ectopic kidney develop in adulthood and during the neonatal period, and congenital thoracic ectopic kidney rarely develops in children. Most patients are asymptomatic, and the treatment depends on the diagnosis. Herein, we report a rare case of ectopic thoracic kidney associated with a diaphragmatic hernia in a 15-month-old male infant, who presented with periodic severe irritability. The thoracic ectopic kidney was detected as a mass in the right base of the chest on routine chest radiography.

  • Sorghum seedlings lacking one of the phytochromes, phyB, have elongated internode, suggesting that they may have an alteration in gibberellin physiology. To test the possibility that phyB mutations affect seedling gibberellin perception and metabolism, the responsiveness of wild-type and phyB-1 seedlings to exogenous $GA_3$ was investigated. The phyB-1 showed higher internode elongation rate than the wild type in response to lower concentrations of exogenous $GA_3$ application, showing that the mutation causes an increase in responsiveness to GA. However, at the higher concentrations of $GA_3$ application, phyB-l and wild-type showed similar elongation rate, impling that responsiveness to higher concentrations of GA is not controlled by phytochrome. These results suggest that, although GAs are required for internode elongation, phyB does not act primarily by changing absolute levels of GAs but rather by decreasing seedling responsiveness to GAs at lower concentrations.

  • Polycystic kidney disease (PKD) is characterized by multiple cysts within the renal parenchyma and is a common heritable disease in humans, dogs, and cats. However, a few cases of PKD have been described in captive pygmy hippopotamuses. Bilateral PKD was observed in a 33-year-old, 198-kg female pygmy hippopotamus during its necropsy in Seoul Zoo on 15 January 2013. The diagnosis of PKD was confirmed by gross findings and histopathological examination. One kidney was slightly enlarged, and the lower portion of other kidney contained a large cyst filled with light yellow, watery fluid. Both kidneys had numerous, variably sized fluid-filled cysts of 2 to 20 mm in diameter. Considerable portions of the renal cortex and medulla were replaced by cysts. Microscopic inspection showed that the cysts were lined with low cuboidal to flat epithelial cells. The present case report of PKD in a pygmy hippopotamus is the first in Korea.

  • A 14-year-old intact male Siberian Husky was presented with hematuria, lethargy, and anorexia of 1-month duration. The physical examination revealed mild abdominal distension and pain. The hematology and serum chemistry revealed anemia and severe azotemia. The radiographic examination revealed renomegaly and the ultrasonographic examination, indistinct cortico-medullary junction, increased renal cortex echogenicity, and irregular margination. The urinalysis showed proteinuria and hematuria. The differential diagnosis included renal failure, cystitis, pyelonephritis, and neoplasia. The patient's condition continued to deteriorate, and the dog eventually died. The gross findings from the necropsy revealed hemoperitoneum and a bilateral renal mass. HSA was diagnosed by histopathological examination. This case report describes primary bilateral renal hemangiosarcoma (HSA), which is uncommon in dogs.

  • The primitive gonad development in Paralichthys olivaceus was classified into (ⅰ) primordial germ cell (PGC), (ⅱ) genital ridge type (GRT), (ⅲ) primitive gonad type I (PGT I) and (ⅳ) primitive gonad type II stages. In the control group, PGC was recognizable on the 3rd days after hatching, and the primodial gonad after 24th days, while it was around the 22nd day after hatching in the group exposed to PCBs 3.0 $\mu\textrm{g}$/L for 30 days. Likewise, the progress of kidney development was recognized in four stages; unitubular type of mesonephric duct (UTMD), the branched mesonephric duct (BMD), convoluted tubule formation (CTF) and glomerulus appearing (GA) stage. It was structurally completed between the 25th and 30th day after hatching in two groups. There was no significant difference (p>0.05) in the time scale of development of gonad, and kidney between control and the PCBs - exposed group.

  • In this paper, an automatic extraction method of glomerulus region from human renal tissue image is presented. The important information reflecting the state of kidneys richly included in the glomeruli, so it should be the first step to extract the glomerulus region from the renal tissue image for the further quantitative analysis of the renal condition. Especially, there is no clear difference between the glomerulus and other tissues, so the glomerulus region can not be easily extracted from its background by the existing segmentation methods. The outer edge of a glomerulus region is regarded as a common property for the regions of this kind ; a two- dimensional Gaussian distribution is used to convolve with an original image first and then the image is thresholded at this blurred image ; a closed curve corresponding to the outer edge can be obtained by usual pattern processing skills like thinning, branch-cutting, hole-filling etc., Finally, the glomerulus region can be obtained by extracting the area in the original image surrounded by the closed curve. The glomerulus regions are correctly extracted by 85 percentages and experimental results show the proposed method is effective.

  • The processing conditions for producing and edible alginate film from sea tangle were investigated by measuring water vapor permeability (WVP), tensile properties and colors of film. The alginates were extracted with $3\%$ sodium carbonate ($Na_2CO_3$) solution for 5 hrs, and the alginate films were prepared with extracted sodium alginates, D-gluconic acid lactone, $CaCO_3$ and various plasticizers, As the concentration of alginate in making the film was increased, the WVP and elongation of the film were decreased and the tensile strength was increased. The higher amount of plasticizer showed the higher WVP and elongation, and the order of various plasticizers in increasing the WVP and elongation of the film was glycerol, polyethylene glycol, and sorbitol. The addition of sorbitol in the film showed the highest value (89.57) in lightness of Hunter color system and the film added polyethylene glycol had the highest values (-1,12 and 11.4) in redness and yellowness.

  • Diabetic nephropathy is a major and representative complication of type 2 diabetes. Hyperglycemia increases the incidence of diabetic nephropathy, and induces kidney inflammation, thereby causing renal fibrosis, which is an important factor in the pathogenesis of diabetic nephropathy. This study investigated the effects of blackcurrant extract (BLC), which has been implicated in diabetic nephropathy in db/db mice, on glomerular fibrosis and renal dysfunction. The results showed that BLC consumption in type 2 diabetic db/db mice ameliorated diabetes-related metabolic disorders, such as insulin resistance and renal dysfunction, and significantly attenuated renal inflammation and renal fibrosis in diabetic nephropathy. In conclusion, these findings suggest that BLC consumption may help prevent renal fibrosis, inflammation, and consequent diabetic nephropathy.
