Five-month-old a female mongrel puppy weighing 3.5 kg showed no systemic disorder and particular discomfort except abdominal distension at the first visit. On physical examination an irregular abdominal mass was palpated. One month later she was clumsy and uncoordinated. In addition, lethargy and anorexia were appeared. Then she became comatose and died in spite of initial therapy. In radiographic examination enlargement of both sides of kidney was observed. The hematological examination the dog had WBC of 16,250/$\mu$l, RBC of $7.2{\times}10^6$ $\mu$l, PCV of 32%, total protein of 8.0 g/dl, and fibrinogen of 900 mg/dl. In serum chemistry BUN was 87.4 mg/dl and creatinine was 5.1 mg/dl. Urinalysis revealed pH of 5.6, SG of 1.009 and protein of 500 mg/dl. In urine sediment test many RBCs, leukocytes, inflammatory cells and a few epithelial cells were observed. On histopathologic examination the size of right and left kidney were 15 cm, 16 cm in length, 6 cm, 6 cm in widths, respectively. Both sides of kidney were filled with brown-orange fluid and had irregular capsular surface. The cysts of various sizes were located throughout the cortex and medulla. No abnormality was found in any other organs. Histologically, cyst was lined by cuboidal to slightly flattened tubular epithelium and surrounded by mature fibrous connective tissue. Glomeruli, tubule and renal pelvis remained normal between cysts and exfoliated epithelial cells.

The present study was done with two aims. First, to evaluate the radiographic measurements of liver volumes in normal and hepatomegaly dogs induced by carbon tetrachloride. Second, to investigate quantitative tissue echo pattern by ultrasonography. Gray level histogram of the normal liver and the kidney were estimated with carbon tetra-chloride intoxication. In normal, r-square for liver volume to body weight was 0.93372, and this showed direct linear regression. Gray level histograms of the normal liver and the kidney were $19.150{\pm}2.490$(mean${\pm}$SD) and $13.175{\pm}2.686$(mean${\pm}$SD) respectively(p < 0.01). Liver parenchymal echogenicity was more hyperechogenic than kidney cortex echogenicity. Liver/Kidney ratio was $1.504{\pm}0.313$ and it can be used relative comparison of liver and kidney parenchymal echogenicity. In carbon-tetrachloride($CCl_4$) intoxication, changes of liver volume appeared to increase up to 24 hours after administration (p < 0.05), and decreased gradually to normal level after 2~5 days. Gray level histogram of liver parenchyma decreased up to 24hours (p < 0.01) after intoxication and then gradually increased to normal level. But that of kidney cortex had no significant change. Liver/Kidney ratio also decreased by 2 days(p < 0.01) and then gradually increased to normal level. On histopathologic features of hepatic tissues in carbon tetrachloride intoxication, both coagulative necrosis of hepatic cell and hemorrhage of centrilobular & midzonal area were identified. Conclusively, plain radiography is a useful diagnostic method for evaluating liver volume in mild hepatomegaly. Especially, it is considered that an adequate numerical processing of the liver length, depth and thoracic width and depth measurement would be helpful. Using gray level histogram, ultrasonographic evaluation was useful objective methods in early diagnosis of diffuse hepatic disease.

The conclusions after studying the rules and the principles of the six-drugs mixing forming the prescription of Yukmijihwanghuan(六味地黃丸) are as follows: 1. Yukmijihwanghuan cares for the three viscera; the liver, the spleen and the kidney and the three entrails; the urinary bladder, the gall bladder, and the stomach and it strengthens them as well. The drug can be used mainly for the cure of the Three Yang Channels of Foot and the Three Yin Channels of Foot. 2. The three drugs of Yukmijihwanghuan; Rehmanniae Radix, Dioscoreae Rhizoma, Corni Fructus altogether has the tonifying effect and the other three; Alismatis Rhizoma, Moutan Cortex, Poria has the purging effect. The first three kinds of drugs tonifies and the last three kinds of drugs purges. While these two groups of drugs are pitted against each other, they also balance each other harmoniously increasing the curative effect(remedial[curative] value). 3. Yukmijihwanghuan cools off the lung which is under metal category, helps the spleen, an earth category to be strong. It also adds the Water Qi to the kidney so that it stabilizes the Fire Qi. 4. Yukmijihwanghuan helps the kidney strongly, helps the urine to be excreted well, cools down the Fire Qi and makes dry things wet. 5. Rehmanniae Radix, the principal drug of Yukmijihwanghuan and Corni Fructus, the minister drug of the medicine have a taste of thick and are materially heavy. The two drugs do the descending action that it tonifies Yin Qi and adds Essence of Life. The other ingredients of Yukmijihwanghuan; Moutan Cortex, Poria, Alismatis Rhizoma have effects on lowering the Fire Qi. If Fire Qi descends, then Water Qi ascends. Yukmijihwanghuan has an efficacy of lowering Fire Qi and increasing Water Qi.

In order to determine possible relationships between the renin-angiotensin system and nephron heterogeneity, we compared the response of renin release and the angiotensin-converting enzyme (ACE) activity from different areas of the rat kidney. We used the renal cortical slices from the capsular surface to the juxtamedullary junction. Slices from outer one-third of the cortex were designated as outer cortical slices (OC), middle one-third as midcortical slices (MC), and inner one-third as inner cortical slices (IC). The renal renin content markedly decreased from OC and MC to IC. The basal lenin release was higher in OC than in MC or IC. On the contrary the percent change of renin release in response to L-isoproterenol was significantly higher in MC than in OC or IC. By TMB-8, the renin release in MC by $231{\pm}21%$ was higher than OC by $171{\pm}19%$ or IC by $$162{\pm}19. Angiotensin II suppressed renin release in OC and MC by $68{\pm}2,\;71{\pm}4%$ respectively, but only $40{\pm}7%$ in IC. The ACE activity was higher in IC than in OC, MC, medulla and papilla. The present data indicate that renin content and basal lenin release gradulally decreased from outer (OC) to inner (IC) cortex. The renin release in response to beta-adrenergic agonist, L-isoproterenol and intracellular calcium antagonist, TMB-8 were higher in MC than in OC and IC, but angiotensin II suppressed renin release less in IC than in OC and MC. It is suggested that juxtaglomerular cells of outer, mid-and inner cortices show a difference in renin release response to the stimuli.

Whether there exists a sympathetic neural mechanism regulating the expression of aquaporin (AQP) water channels in the kidney was investigated. Male Sprague-Dawley rats were treated with reserpine (1 mg/kg, IP), and the expression of AQP1-4 proteins was determined in the kidney one day thereafter. Following the treatment with reserpine, the systolic blood pressure measured in a conscious state was significantly decreased in the experimental group compared with that in the control $(83{\pm}8\;vs\;124{\pm}6\;mmHg;\;n=6\;each,\;P＜0.05)$. The expression of AQP2 proteins was decreased in the cortex, outer medulla, and inner medulla. The decrease of AQP2 proteins was in parallel in the membrane and the cytoplasmic fractions, suggesting a preserved AQP2 targeting. No significant changes were observed in the expression of AQP1, AQP3, or AQP4. Neither basal nor AVP-stimulated formation of cAMP was significantly altered. These results suggest that the sympathetic nervous system has a tonic stimulatory effect specifically on the expression of AQP2 water channels in the kidney.

This study was performed to investigate the antitoxic effect of Oenanthe javanica extracts on orally administered mercury compound. Adult male ICR mice were exposed to methylmercuric chloride (CH3HgCl)through drinking water. The control, mercury treated and Oenanthe javanica treated groups not showed significant differences in mean body and organ weights of mice. The distribution of mercury in the cerebellum, kidney, liver and spleen of the mouse were examined according to a histochemical mathod. Grains of mercury traces were located in the purkinje cell and granular layers of the cerebellum and cortex of kidney respectively. Lesser staining of the grains was seen in the collecting tubules of medulla. in the liver, mercury accumulations were present primarily in the hepatocytes around portal area containing interlobular bile duct, artery and portal vein. Also grains of mercury traces were accumulated in the white pulp of the spleen. In the group of Oenanthe javanica extracts, staining intensity of mercury was decreased in the Purkinje cell layer of cerebellum and in the portal area of liver respectively. Staining patterns in kidney and spleen of extracts group were similar to that of only mercury treated group.

We report septicemic colibacillosis accompanied by white-spotted kidney in a 30-day old female Holstein-Friesian dairy calf. Grossly, there were numerous white spots sized average 0.5cm in diameter in both kidneys. When sectioned sagittally, there were radially oriented gray streaks extending outward and reaching the renal cortex. The renal papillae were ulcerated, white to gray in color and very friable. Histologically, there was extensive purulent inflammation characterized by severe neutrophilic cellular infiltrations in the tubular lumens and interstitia. In addition, massive coagulative necrosis were found in the apices of papillae. Numerous Gram-negative bacterial colonies were detected in both of the renal and lung tissues. Beta-hemolytic Escherichia coli (E. coli) was purely isolated from the renal parenchyma, peritoneal surface and pleural surface. Based on the above results, we suggest that the generalized septicemia with pyelonephritis may be oriented from the lower urinary tract infection with E. coli in this case.

Klotho deficiency is an early event in acute kidney injury (AKI) that exacerbates acute kidney damage. The present study explored the expression of Klotho and inflammation related factors in cisplatin-induced AKI. Rats (n = 18) were treated with cisplatin intraperitoneal injection (5 mg/kg) or left untreated as controls (n = 6), then sacrificed at 5 (n = 6) and 10 days (n = 6) treatment. Five days after cisplatin injection, the serum kidney enzymes and kidney cell apoptosis were significantly increased. Moreover, the expression of Klotho was decreased when compared to the control group, especially in the cortex and outer medulla regions. In contrast, inflammation related signals including nuclear factor kappa B, tumor necrosis factor-${\alpha}$, and tumor necrosis factor-like weak inducer of apoptosis were enhanced. However, 10 days after cisplatin injection, Klotho expression was enhanced upon both IHC and Western blot analysis, with slightly recovered renal function and decreased apoptosis. Furthermore, inflammation related signals expression was decreased relative to the 5 days group. Overall, this study confirmed the opposite expression patterns between Klotho and inflammation related signals and their localization in cisplatin-induced AKI kidney.

Objectives : The Gyotae-hwan formula has traditionally been applied to conditions of fearful throbbing[怔忡] and insomnia due to disharmony of the Heart and Kidney, of which experimental and clinical research has been carried out while those on its pathological mechanism and constituent compatibility have been inadequate. Methods : Pathological mechanism and constituent compatibility of the Gyotae-hwan formula as listed in the 『Comprehensive Medicine According to Master Han』(韓氏醫通) and the『Simple Recipes for Four Disciplines』(四科簡效方) were analyzed. Findings from recent researches searched using the keywords '交泰丸' and '교태환' in the OASIS and CNKI databases were referenced as well. Results : The Gyo-tae hwan was first mentioned in the text 『Comprehensive Medicine According to Master Han』by Mao Han in terms of constituent medicinals and application while measurements and name of formula were not listed while the concept of harmony between the Heart and Kidney was mentioned. In the『Simple Recipes for Four Discipline s』 written by Shixiong Wang, measurements of constituent medicinals, usages and name of formula were finally mentioned, along with its efficacy to treat fearful throbbing and insomnia due to disharmony between the Heart and the Kidney. Conclusions : In conclusion, the Gyo-tae hwan uses Coptidis Rhizoma as chief herb and Cinnamomi Cortex as assistant herb to change the state of disharmony between the Heart and Kidney to a harmonious state, treating insomnia and fearful throbbing.
