The present study was aimed at investigating whether there are changes in the expression of nitric oxide synthase (NOS) in relation with the unclipping-induced fall of blood pressure in two-kidney, one clip (2K1C) hypertension. Male Sprague-Dawley rats were made 2K1C hypertensive by clipping the left renal artery for four weeks. Sham-clipped rats served as control. The expression of endothelial constitutive (ec) NOS proteins and tissue levels of NO metabolites were determined in the kidney. Systolic blood pressure was significantly increased in clipped rats compared with that in the control. The development of hypertension was associated with decreases in the expression of ecNOS proteins and tissue levels of NO metabolites in the clipped kidney. The blood pressure at twenty-four hours after removal of the renal arterial clip fell to the control level. Accordingly, in the unclipped kidney, the expression of ecNOS proteins and tissue contents of NO metabolites were increased to the control level. The contralateral kidney was not affected by the development or reversal of hypertension. It is suggested that an enhanced expression of ecNOS in the unclipped kidney is an important component in the reversal of renovascular hypertension.

The direct effect of isoproterenol on renal function, when given intravenously, is usually obscured by its potent hypotensive action. To obviate the latter action, isoproterenol was infused directly into one renal artery of the dog, the other kidney serving as a control for the general action. And following results were obtained. In the first series of experiments, the directic action of isoproterenol was ascertained. $1.0\;{\mu}g/kg/min$. reduced on both kidneys the urine flow, clearances of PAH and creatinine, as well as the amount of sodium excreted, but the effect was weaker on the experimental side than on contralateral side. With $0.1\;{\mu}g/kg/min$., two cases among 6 experiments showed marked diuresis, two cases no apparent effect, and another two marked antidiuresis on the experimental kidney, whereas the contralateral kidney exhibited antidiuresis in all cases. Further reducing the dose unmasked the diuretic action on the ,experimental kidney. In another series, the effects of isoproterenol on the blood flow distribution within the kidney and on sodium concentration gradient within the kidney tissue were observed. $0.05\;{\mu}g/kg/min$ isoproterenol markedly increased the medullary plasma flow and slightly increased total renal plasma flow and glomerular filtration rate, along with concomitant increase in the amount of sodium excreted and osmolar clearance, and decrease in reabsorption of free water. Sodium concentration gradient markedly decreased in the experimental kidney, reaching 2/3 of the value observed in the contralateral kidney at the papilla. It is thus concluded that isoproterenol exerts a diuretic action, when infused directly into a renal artery, and the mechanism of the action rests on its hemodynamic action, substantiated as the increase in glomerular filtration and in the medullary blood flow, resulting in washout of hyperosmolality produced by the coutercurrent multiplier system.

Objectives : There are two aspects of Korean medicine perspective on teeth, including the fact that the teeth reveal the thrift and decay of kidney as 'Goljiyeo', and that SujokYangmyeongGyeong flows into the teeth. Since the interrelationships of the two have not been sufficiently studied, this study attempts to investigate the relationship between kidney and Yangmyeong on teeth based on the literature. Methods : In "Huangdineijing", this study examined whether the connection between kidney and Yangmyeong respectively for the teeth appeared, and reviewed the sentences that can simultaneously examine the relationship between kidney and Yangmyeong. This study referred to previous medical books such as "Nanjing" as needed. Results & Conclusions : This study confirmed that there is recognition that kidney and Yangmyeong affected the teeth in a complex way in various provisions such as the provision of "Joksoeumgijeol" in "Lingshu-Jingmai". Kidney and Yangmyeong produce wantonness(血氣) in food(水穀) and transform it to perform the process of producing the vitality together. However, there is an aspect that they oppose each other as acquired spirit and inherent vitality. Therefore, inherent and acquired incongruities may occur depending on the situation, which can be a cause of triggering the pathogenesis of the tooth. : This study has found herbal combinations used frequently in Korean medicine formulas used for insomnia treatment, and a result of network analysis composed of four communities. Each community consisted of herbs in affiliation of Yookmijihwangtang(六味地黃湯) and Samultang(四物湯), Bohyulchunghwatang(補血淸火湯) and Ondamtang(溫膽湯), Jungjihwan(定志丸) and Sanjointang(酸棗仁湯).

Objectives : The comparison of symptoms of hypoadrenocorticism with symptoms according to spleen and kidney show how many points of similarity they are. And by analysis of symptoms of hypoadrenocorticism it was examined that Kidney Jeonggyeok help to cure many different symptoms including symptoms of hypoadrenocorticism. Methods : The symptoms of hypoadrenocorticism were compared and analyzed according to standards of the book of korean traditional medical pathology. First, this study was designed to show to found out how many symptoms of hypoadrenocorticism belong to symptoms of kidney qi-deficiency and slpeen qi-deficiency and how similar they are. Second, the symptoms of kidney qi deficiency were compared with the indicant of kidney Jeonggyeok suggested by two of korean traditional doctors to find out kidney Jeonggyeok can help to cure symptoms of kidney qi deficiency. And then on the basis of those, the symptoms of hypoadrenocorticism were compared with the symptoms of kidney qi deficiency. Results : The hypoadrenocorticism seems to be kidney yang(陽) deficiency. But because hypoadrenocorticism doesn't have body temperature decline, symptoms of hypoadrenocorticism are more similar symptoms of kidney qi deficiency than symptoms of kidney yang deficiency. The symptoms of hypoadrenocorticism seems to be correlated with the functions of spleen. But because of vomiting and pigmentation(skin and mucous membrane), they seem to have less to do with the functions of spleen than the functions of kidney. The comparison analysis of indicant of Kidney Jeonggyeok and symptoms of kidney qi deficiency shows that acupuncture stimulation help to cure kidney qi deficiency and hypoadrenocorticism. Conclusions : Symptoms of hypoadrenocorticism are expected to be more similar symptoms of kidney qi deficiency. And Kidney Jeonggyeok is helpful for treatment of Kidney qi deficiency and hypoadrenocorticism.

Objectives : This paper compares and analyzes Liu Hejian's kidney fluid nourishing treatment methodology with Zhu Danxi's kidney tonifying treatment methodology. Methods : The two doctors' medical theories and treatment formulas were examined to study how their medical arguments manifested in clinical application. Results : Both doctors emphasized the kidney. Liu pursued the treatment of balance based on the theory of the original qi of the Taiyitianzhen(太乙天眞), while Zhu tried to prevent the frenetic stirring of the ministerial fire by restraining one's desires. In nourishing kidney fluid, Liu sometimes used hot medicinals to treat kidney deficiency patters, where medicinals that tonify the kidney fluid were not defined clearly. Zhu, on the other hand, defined formulas and medicinals that would tonify the kidney yin clearly. Conclusions : The tradition of emphasizing the body's yin qi based on the kidney has been continued from Liu Hejian to Zhu Danxi, during which the pathology of fire and heat were examined thoroughly. In clinical application, various and specific ways of controlling the fire heat were developed.

In this study, we wanted to determine if the respirotropic JMK strain of infectious bronchitis virus(IBV), which has a spike glycoprotein gene that is 99% similar to the nephropathogenic Gray strain of IBV, could adapt and cause lesions in the kidney following intracloacal passage in chickens. Two day old specific pathogen free(SPF) cchickens were infected with Gray and JMK strains by the intraocular and cloacal route. Several tissue samples were collected at various times. Viruses were recovered from more tissues and earlier in the infection from chickens infected cloacally than chickens infected intraocularly. Virus was isolated from the kidney of chickens infected with Gray by the intraocular route and JMK by the intracloacal route, but not from chicken given JMK the intraocular route. Histopathologically, interstitial nephritis was observed in Gray infected chickens. However, viral RNA or antigen were not detected in the kidney by in situ hybridization and immunohistochemistry. We further passaged the JMK strain ten times in two day old SPF chickens using cloacal inoculation. We examined the virus titer and histopathological change in the kidney at each passage level. The amount of virus recovered from the kidney was stable throughout this serial passage and the passaged virus did not caused renal damage. Further, virus could not be isolated from the kidney when chickens were infected with the passaged virus by the intraocular route. We conclude that the JMK strain has a strict upper respiratory tract tropism since cloacal passage did not produce nephrotropism or nephropathogenicity.

Background and Objectives : There are four kinds of formulas for invigorating the kidney to cure its asthenic syndrome based on the types of preparation formulas : Boshintang, Boshinhwan, Boshinsan, and Boshingaeng. There are 16 kinds of Boshintang, 28 kinds of Boshinhwan, 3 kinds of Boshinsan, and one kind of Boshingaeng. Combination of herbal medicines, carried out in formulas for invigorating the kidney, consists of various kinds depending on medical scientists' personal experience in medical treatment without any general principles, which makes it difficult to apply it to clinical use. The objectives of this study lie in theoretical establishment of Boshintang for curing the asthenic syndrome of kidney through analyzing the component medicines and combination principles of Hyeongok's Boshintang, and furthermore, maximizing the clinical use of Boshintang. Methods : This study analyzed the component medicines and combination principles of Hyeongok's Boshintang based on the theory for properties and tastes of herbal medicines from the ${\ulcorner}$Yellow Emperor's Canon of Internal Medicine${\lrcorner}$ , the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine, and the five elements doctrine. Hyeongok's Boshintang is an even prescription, composed of 6 kinds of ingredients : No.1 Fructus Lycii (3don;11.25g), No.2 Radix Polygoni Multiflori (1don:3.75g), No.3 Sarcucarpium Corni (1don), No.4 Fructus Schisandrae (1don), No.5 Rhizoma Anemarrhenae (5poon: 1.875g), and No.6 Cortex Phellodendri (5poon) Results : There are three methods for curing the asthenic syndrome of kidney according to the five elements doctrine : invigorating the kidney, invigorating the lung and purging the spleen. First, if you suffer from the asthenic syndrome of the kidney, you need to invigorate your kidney. There are two available methods, including taste and property invigoration according to the theory for properties and tastes of herbal medicines. They each imply the bitter taste and the cold property invigorate the kidney. In the case of taste invigoration, two herbal medicines with bitter taste, Fructus Lycii and Radix Polygoni Multiflori, are combined into the principal and assistant herbal medicine, respectively. For property invigoration, two herbal medicines with the cold property, Rhizoma Anemarrhenae and Cortex Phellodendri, are combined into adjuvant herbal medicines. Secondly, if you suffer from the asthenic syndrome of the kidney, you need to invigorate your lung which is mother in the mother-child relationship in inter-promotion among the five elements. There are two methods to invigorate the lung, including taste and property invigoration according to the theory for properties and tastes of herbal medicines. They each mean the sour taste and the cool property invigorate the lung. Therefore, it is important to use sour herbal medicines for taste invigoration and cool ones for property invigoration. Both bitter and cool herbal medicines, Rhizoma Anemarrhenae and Cortex Phellodendri, are combined into adjuvant herbal medicines. Lastly, if you suffer from the asthenic syndrome of the kidney, you need to purge your spleen which is an element being surpassed in the relationship between the elements surpassed and ones not surpassed in inter-restraint among the five elements. There are two methods to purge the spleen, which include taste and property purgation according to the theory for properties and tastes of herbal medicines. Taste purgation means to purge the spleen with bitter taste and property purgation to purge the spleen with cool property. Therefore, it is important to use bitter herbal medicines for taste purgation and cool ones for property purgation. Both bitter and cool herbal medicines, Rhizome Anemarrhenae and Cortex Phellodendri. were combined to purge the spleen and invigorate the kidney. In addition, Rhizome Anemarrhenae and Cortex Phellodendri are combined as dispatcher herbal medicine, reinforcing the kidney energy. Conclusions : First, to cure the asthenic syndrome of the kidney, the methods of invigorating the kidney and the lung, and purging the spleen should be used according to the five elements doctrine. Secondly, herbal medicines appropriate for those treatment methods should be chosen according to the theory for properties and tastes of herbal medicine and thirdly, the combination of those herbal medicines should be carried out according to the theory for principal herbal medicine, assistant herbal medicine, adjuvant herbal medicine, dispatcher herbal medicine. As a good example, Hyeongok's Boshintang is combined according to the above theories. In conclusion, this formula was created by applying to the theory for properties and tastes of herbal medicines.

Purpose: The purpose of this study was to discover kidney transplant and hemodialysis patients' quality of life(QOL) and provide basic data to improve their QOL. Method: One hundred two hemodialysis patients and 106 kidney transplant patients were given a self-administered questionnaire from Mar. 6 to Mar 31, 2006. The instrument consisted of demographic variables, therapeutic-related characteristics and QOL. Collected data was processed using the SPSS 12.0 statistical program for real numbers, percentages, ANCOVA, t-test, ANOVA, Stepwise multiple regression and the Scheffe test. Results: Kidney transplantpatients' QOL was higher than hemodialysis patients. The demographic variables which showed a significant difference in overall QOL were religion, children and monthly income for kidney transplantpatients and educational background for hemodialysis patients. The therapeutic-related variable which showed a significant difference in overall QOL was the patients' perceived health condition for both groups. The influencing factor on overall QOL for both groups was the health condition perceived by themselves. The total variance of the variable for QOL was 42% for kidney transplant patients and 19% for hemodialysis patients. Conclusion: This study revealed that kidney transplant patients have a higher QOL and how patients perceive their health is the strongest influencing factor for QOL. However, there is a large difference between the demand and supply of kidney donors. To solve this problem the standards for donation should be reviewed and revised.

Background: Kidney cancer is the third most frequent urologic cancer in Lebanon after prostate and bladder cancer, accounting for 1.5% of all diagnosed cancers. In this paper, we report the histologic characteristics and distribution of kidney cancer, never described in Lebanon or the Middle East. Materials and Methods: Pathology results of operated kidney cancer were collected during a two year period (2010-2011) from two different Lebanese hospitals (Hotel-Dieu de France University Hospital and Saint Joseph Hospital). A total of 124 reports were reviewed and analyzed according to WHO classification of 2009. Results: The 124 patients diagnosed with kidney cancer had a median age of 62.4 [18-86], 75% being men and 25% women. Some 71 % of the lesions were renal cell carcinoma (RCC), 25.8% had a urothelial histology, 1.6% were lymphomas and 1.6% were metastases to the kidney. Patients having RCC had a median age of 60.3 [18-85], 77.3% were men and 22.7% women. Of the RCCs, 59.1% were clear cell carcinoma, 22.7% papillary, 11.4% chromophobic, 3.4% rom the collecting ducts of Bellini and 3.4% were not otherwise classified. Conclusions: Histological distribution of Lebanese kidney cancer seems unusual when compared to the literature. The percentage of urothelial renal pelvis tumors is strikingly high. Moreover, clear cell carcinoma accounts for only 59.1% of RCCS in contrast to the 75% described elsewhere, while papillary carcinoma represents more than 22.7% compared to 10%.
