  • A female 8-year-old Pug weighing 7.3 kg and a female 10-year-old Maltese dog weighing 3.5 kg showing anorexia and vomiting for a few weeks were referred to Veterinary Medical leaching Hospital, Seoul National University. Radiographic findings were an enlarged right kidney in a pug dog and a radiopaque material on the right ureteral region lateral to the third lumbar vertebrae with indefinite right kidney contour in a Maltese dog, repectively. Excretory urography performed in a Pug dog revealed a poor opacified enlarged right kidney with absent of pelvic recesses and pelvic dilation with proximal ureteral dilation on contralateral kidney. Ultrasonographic findings were enlarged kidney with dilated pelvis and echogenic sediment within the medulla in both dogs and especially an engorged proximal ureter and a thin rim of functional renal tissue remains in a Maltese dog. Those diagnostic findings indicated high possibility of pyelonephritis and these were confirmed by pathologic examination. Radiography and ultrasonography, although not giving final diagnosis for pyelonephritis, are useful for assessment and diagnosis of pyelonephritis.

  • For the purpose of investigation to identify the quantities of heavy metals contained in the tissues of the Korean people, a series of analyses was conducted with atomic absorption spectrophotometry to measure the amount of lead, cadmium and copper distributed in various tissues, such as brain, liver, kidney, heart, lung, spleen, large intestine, hair, muscle, fat, stomach, costal cartilage, blood and urine, obtained from 30 cadaverous bodies who were believed not exposed to the said heavy metals during their life time either occupationally or therapeutically. 1. Lead content: Inter-individual difference was noted in lead contents in each tissue, vis., the average content of lead in hair was the highest with $14.90{\pm}9.74ppm$. The next was in costal cartilage that contained $5.56{\pm}3.86ppm$. The average contents of lead in liver, kidney and muscle were the lowest in value, showing $1.11{\pm}0.92ppm,\;0.73{\pm}0.48ppm\;and\;0.06{\pm}0.06ppm$, respectively, The lead contents in tissues of children under the age of 10 were significantly lower than those of adults, and the higher values were shown in males than in females in general. The lead contents in most of the tissues such as hair, costal cartilage, kidney, lung, fat, stomach, large intestine, heart, muscle and urine were well correlated with age. 2. Cadmium content: The average content of cadmium in kidney appeared to be the highest of other tissues showing $20.72{\pm}9.82ppm$, and liver came next with the value of $1.17{\pm}0.99ppm$. It was estimated that 83.9% of the total cadmium absorbed into the body was stored in kidney, 4.796 in liver, and the remaining 11.4% was distributed in the rest of the tissues. Cadmium contents in tissues showed difference between both sexes showing higher values in the females than in the males, which was quite contrary to the lead content. Cadmium contents in tissues steadily increased in amount with age, showing a significant correlation with age in all tissues. 3. Copper content: The average content of copper in hair was the highest with $10.36{\pm}2.21ppm$, and liver came next with $6.31{\pm}1.24ppm$. The copper that was absorbed into the body was distributed in each tissue: 29.9% in hair, 18.2% in liver, $5{\sim}11.0%$ in brain, heart and kidney, and $3.0{\sim}3.5%$ in stomach, blood, and lung. The copper contents in tissues of children under the age of 10 showed significantly higher values in liver, kidney, heart and large intestine than those of the adults. The copper contents in brain, costal cartilage and fat were well correlated with age showing the highest correlation coefficient of 0.870 (p<0.01) in brain tissue. There was no difference in copper contents in tissues between both sexes, and the values were, in general, lower than those for Japanese.

  • Alcohol is a major risk factor for several diseases and excessive, long-term alcohol consumption are caues physical alteration-fatty liver, hepatitis, cirrhosis, breaking down, Wernicke-karsakoff's syndrome, weight loss, and poor immunity-in virtually all organ and tissue. This study was observed that liver, kidney, and stomach were altered in mouse by the effect of chronic alcohol administration. The mouse were sacrificed to obtain the tissue after mouse were orally injected with 25 % ethanol $18m{\ell}/kg/day$ for 120days. The tissue were stained by hematoxylin and eosin and then observed by light microscope. The results of this study were as follows : 1. The congestion was appeared in liver after 120days alcohol admistration. 2. The destruction of glomerulus were increased and the parietal cell of Bowman's capsule were swelled such as cuboidal cell after 120days alcohol administration. The congestion was appeared in alcohol administrated group. 3. The mucosa and gastric pit were destructed and the ulceration was appeared in stomach after 120days administration. The parietal cells and chief cells were damaged. Above results were shown that the tissue were damaged by chronic alcohol administration.

  • The study was conducted targeting 25 patients who underwent the respiratory gated radiation therapy in the abdominal region at Radiation Oncology of a University Hospital from December 2013 to June 2014 and types of cancer included liver(64%), CBD(8%), gastric(8%), GB(8%), pancreas(8%), SMA(4%). The means of ITV and PTV volume are 471.44 cm3 and 425.48 cm3, showing an increase in volume. Normal tissue volume was also found to have increased due to the increase of the section selected from PTV section to ITV section. Right kidney showed a significant increase in differences between increase in normal tissue volume, increase in target volume and increase in therapy irradiation area and difference between the means of dose applied to normal tissue. There was no significant difference in the mean dose applied to normal tissue according to the respiratory average. Both kidneys showed a significant difference in the difference between mean doses of target moving and normal tissue. In this study, both therapy methods through PTV section and ITV section volume setting were appropriate for protection doses of normal tissue and distributed over 95% of the prescribed dose and therefore, it is considered to be okay to be optionally used depending on the patient's therapeutic purpose. But in order to minimize the unexpected side effect, the plan of PTV section and ITV section should be established and used by evaluating normal tissue protection dose.

  • The objective of this study was to investigate the expression and localization of heat shock protein 70 (Hsp70) and its mRNA in the heart, liver, and kidney of acutely heat-stressed broilers at various stressing times. Male AA broilers (n = 100) were randomly divided into 5 groups of 20 birds per group. After 30 d of adaptive feeding at ambient temperature, 80 experimental broilers were suddenly heat stressed by increasing the environmental temperature from $22{\pm}1^{\circ}C$ to $37{\pm}1^{\circ}C$. The 4 groups were heat stressed for 2, 3, 5, and 10 h, respectively. The localizations of Hsp70 protein and mRNA, determined by immunohistochemical staining and in situ hybridization, respectively, were demonstrated to be tissue dependent, implying that different tissues have differential sensibilities to heat stress. Intense Hsp70 staining was identified in the vascular endothelial cell of heart, liver and kidney, suggesting an association between expression of Hsp70 in vascular endothelial cell and functional recovery of blood vessels after heat shock treatment. Ante-mortem heat stress had a significant effect on the expression of Hsp70 protein and mRNA. The quantitation of Hsp70 protein and mRNA were both time and tissue dependent. During the exposure to heat stress, the heart, liver and kidney of broiler chickens exhibited increased amounts of Hsp70 protein and mRNA. The expression of hsp70 mRNA in the heart, liver and kidney of heat-stressed broilers increased significantly and attained the highest level after a 2-h exposure to elevated temperatures. However, significant elevations in Hsp70 protein occurred after 2, 5, and 3 h of heat stressing, respectively, indicating that the stress-induced responses vary among different tissues.

  • To investigate interaction of angiotensin converting enzyme (ACE) inhibitor with local tissue renin- angiotensin system (RAS), changes in gene expression of the RAS components in various tissues in response to chronic administration of an ACE inhibitor, enalapril, were examined in Sprague-Dawley male rats. Enalapril was administered in their drinking water $(3{\sim}4\;mg/day)$ over 8 wk. Plasma and renal ACE activity increased significantly after 4 and 8 wk of enalapril treatment. Renin levels of the plasma and kidney of the enalapril-treated rats markedly increased after 4 wk and decreased thereafter, but still remained significantly higher than those of control rats. Kidney mRNA levels of renin markedly increased after 4 and 8 wk of enalapril treatment, but those of angiotensinogen and ANG II-receptor subtypes, $AT_{1A}$ and $AT_{1B}$, did not change significantly. The liver expressed genes for renin, angiotensinogen and $AT_{1A}$ receptor subtype, but $AT_{1B}$ receptor subtype mRNA was not detectable by RT-PCR. None of mRNA for these RAS components in the liver changed significantly by enalapril treatment. The hypothalamus showed mRNA expressions of renin, angiotensinogen, $AT_{1A}$ and $AT_{1B}$ receptor subtypes. $AT_{1A}$ receptor subtype mRNA was more abundant than $AT_{1B}$ receptor subtype in the hypothalamus as shown in the kidney. However, gene expression of the RAS components remained unchanged during 8-wk treatment of enalapril. In the present study, chronic ACE inhibition increased plasma and renal levels of ACE and renin, but did not affect mRNA levels of other RAS components such as angiotensinogen, ANG II receptor subtypes in the kidney. Gene levels of the RAS components in the liver and hypothalamus were not altered by chronic treatment of enalapril. These results suggest the differential expression of the RAS components in response to enalapril, and localized action and some degree of tissue specificity of enalapril.

  • The sex steroid hormone progesterone is essential for normal development and maturation of the endometrium in preparation for the embryo implantation and the maintenance of pregnancy. Insulin-like growth factor (IGF) system that is composed of IGF-I, IGF-II, IGF binding proteins (IGFBPs) is also involved in the maintenance of pregnancy. In addition, liver, kidney, and uterus is a target tissue for IGF system. However, the effect of exogenous progesterone on IGF system was not elucidated in female rats. Therefore, we investigated the effect of progesterone on insulin-like growth factors (IGFs) and IGF-binding proteins in serum, liver, kidney, and uterus in female ovariectomized rats. IGFs concentration was measured by radioimmuoassay (RIA) and IGFBPs levels by western ligand blotting(WLB). IGF-I concentration was increased in serum, liver, and uterus, but not in kidney of progesterone-treated ovariectomized rats, compared to control (P<0.05). IGF-II concentration was decreased in liver, but not in serum, kidney, and uterus of progesterone-treated rats, compared to control (P<0.05). IGFBP-3 was increased in serum, but not in liver of progesterone-treated rats, compared to control. IGFBP-2 was decreased in kidney, but not in others tissues of progesterone-treated rats, compared to control. These results suggest that progesterone may exert diverse physiological functions via the tissue-specific regulation of IGFs/IGFBPs system in female rats.

  • The overall incidence and mortality of renal cell carcinoma (RCC), the most common kidney cancer, are steadily increasing for reasons that are not fully explained. Our aim was to explore the expression of membrane MHC class I chain-related gene A (mMICA) in human RCC cell lines and tissue specimens, and to determine expression of soluble MICA (sMICA) in serum of patients with renal cell carcinoma, we used flow cytometry (FCM) and immunohistochemistry as well as an enzyme linked immunosorbent assay (ELISA). The results showed that percentage of mMICA expression was significantly increased in human kidney cancer tissues and RCC cell lines (786-O and Ketr-3) than that in healthy adults and human embryonic kidney 293 (HEK293) cell line individuality (P<0.05). sMICA content in healthy adults was negative, but in renal cancer patients was significantly elevated (P<0.05). Our research showed that high expression of MICA in human kidney cancer, this results show that MICA might serve as potential tumor-associated antigen (TAA) in RCC.

  • 1. Objectives The purpose of this study is to investigate the anti-aging and anti-oxidant effects of Hyeongbangjiwhang-tang decoction(HGD) in SD rats. 2. Methods This experiment was used the tissue of kidney, bladder and spleen cells of 6, 52 and 68 weeks old SD rats. Each age group was again divided into three groups. One group, as normal group, was not-treated cells, another group, as control group, was saline-treated cells, and the last group, as experimental group, was HG-treated cells. After culture for 48 hours, each groups measured the level of SOD, GSH, MDA and NO in the tissue of kidney, bladder and spleen cells. 3. Results and Conclusions The activity of SOD were significantly increased in kidney cell of 68 w-HGD group, bladder cell of 52 w-HGD group and in spleen cell of 52,68 w-HGD group compared with those of the control groups. The level of GSH were significantly increased in bladder cell of 52w-HGD group and in spleen cell of 68w-HGD group compared with those of the control groups. The level of MDA were significantly decreased in bladder cell of 68 w-HGD group and in spleen cell of 68w-HGD group compared with those of the control groups. The level of NO were significantly decreased in kidney cell of 68 w-HGD group, bladder cell of 52, 68w-HGD groups, and in spleen cell of 68w-HGD group compared with those of the control groups. These results suggest that HGD(Hyeongbangjiwhang-tang) has anti-oxidant effects in aged rats.

  • Purpose: We present our experience involving the management of this disease, identifying prognostic factors affecting treatment outcomes. Methods: The patients treated for Fournier gangrene at our institution were retrospectively reviewed. Data collected included demographics, extent of soft tissue necrosis, predisposing factors, etiological factors, laboratory values, and treatment outcomes. The severity index and score were calculated. Multivariate regression analysis was used to determine the association between potential predictors and clinical outcomes. Results: A total of 41 patients (male:female = 33:8) were studied. The mean age was 54.4 years (range, 24-79 years). The most common predisposing factor was diabetes mellitus (n = 19, 46.3%). Sixteen patients (39.0%) were current smokers. Seven patients had chronic kidney disease. The most frequent etiology was urogenital lesion (41.5%). The mortality rate was 22.0% (n = 9). Multivariate regression analyses showed that extension of necrosis beyond perineal/inguinal area and pre-existing chronic kidney disease were significant and independent predictors of mortality. Extension of necrosis beyond perineal/inguinal area was a significant predictor of increased duration in the intensive care unit and hospital stay. In addition, pre-existing chronic kidney disease was a significant predictor of flap reconstruction in the wound. Conclusion: Fournier gangrene with extensive soft tissue necrosis and pre-existing chronic kidney disease was associated with poor prognosis and complexity of patient management. Early recognition of dissemination and premorbid renal function is essential to reduce mortality and establish a management plan for this disease.
