Objectives: This study investigated the effect of Korean medicine on an elderly patient with posterior circulation cerebral infarction, chronic kidney disease (CKD), and early neurological deterioration (END). Methods: The patient, who already had CKD, was treated with Korean medicine, comprising herbal medicine, acupuncture, moxa, and cupping combined with Western medicine (antiplatelet, diabetes) and physical therapy. A manual muscle test (MMT) and a modified Barthel index (MBI) were used to observe the treatment effects, and blood tests were performed to check estimated glomerular filtration rate (eGFR), creatinine and blood urea nitrogen (BUN), which represent renal function. Results: After the treatment, MMT, MBI, and renal function scores had increased. Conclusions: This study suggests that Korean medicine can effectively treat posterior circulation cerebral infarction with END in CKD, but further studies should be conducted.

Purpose: Despite meticulous techniques, surgical complications continue to be problematic in kidney transplant recipients. Role of routine stenting to reduce complications is controversial. In this study, we compare incidence of early urological complications, lymphoceles, urinary tract infections (UTI) and graft function; with or without double-J stenting. Materials and Methods: All patients who underwent live related donor renal transplantation from February 2014 to February 2016 were included. Transplants prior to February 2015 were without routine stenting; subsequent transplants were with routine stenting. Patients with neurogenic bladder, previously operated bladder and delayed or low urinary output were excluded. Followup was for at least three months. Descriptive statistics was performed for all parameters. Chi square test and Fisher's Exact test were used for qualitative variables. For quantitative variables, Mann-Whitney test was used to test median difference and independent samples t-test for mean difference. The p-value ${\leq}0.05$ was considered significant. Results: We analysed 74 patients (34 stented and 40 non-stented). There was no difference in the incidence of urinary leak, anastomotic obstruction, lymphoceles or UTI (p>0.4 for all comparisons). However, mean estimated glomerular filtration rate at sixth day, 14th day, one month and two months were 76.1 vs. 61.5 (p=0.025), 72.1 vs. 56.6 (p=0.005), 79.4 vs. 63.1 (p=0.002) and 82.0 vs. 63.3 (p=0.001) in the stented versus non-stented groups. Conclusions: Placement of ureteral stent in renal transplant does not significantly affect the incidence of early urinary complications or UTI. However, graft function is significantly better in stented recipients, at least in the short term.

This study was conducted to investigate the effects of vitamin I supplementation on renal function in high fat diet and adriamycin (ADR) induced experimental nephrotic syndrome in model rats. The effects of vitamin E supplementation on renal function in high fat diet and ADR treated rats were as follows. Kidney weight was decreased by vitamin E supplementation. Serum total protein was increased by the excess supplementation. Blood urea nitrogen(BUN) was decreased by the high supplementation. However, serum albumin and creatinine showed no significant differences between groups. Urinary volume tended to increase by vitamin I supplementation. Urinary urea-N tended by vitamin I supplementation. Particularly glomerular filtration rate(GFR) was significantly decreased by vitamin E supplementation. These results suggested that vitamin E supplementation could alleviate the adverse effects caused in renal function by highfatdiet and ADR treatments.

동적신장검사는 신장기능을 영상화하는 대표적인 방법이다. 동적신장검사에서 저선량 방사성의약품의 사용으로 기존 동적신장검사와 저선량을 사용한 신장검사의 비교를 통한 동적신장검사의 재현성을 평가해 보기로 했다. 본 비교실험을 통해 재현성이 우수할 경우 환자에 투여하는 방사선량을 줄인 동적신장검사법을 활용하고 환자의 피폭을 줄이고자 한다. 감마카메라 장비로는 Orbiter, SymbiaE (Siemens, Germany)를 사용하였고, 2013년 1월부터 2014년 2월까지 370 Mbq (10mCi)을 사용한 환자와 동일 환자 중 2014년 3월부터 2015년 7월까지 185 Mbq (5 mCi)을 사용한 환자를 대상으로 $^{99m}Tc-DTPA$사용 검사 21명과 $^{99m}Tc-MAG_3$사용 검사 20명 총 41명을 대상으로 데이터를 선별하였다. 결과 영상의 Renogram에서 Peak 지점의 프레임을 선택하여 신장의 관심영역과 배후방사능의 관심영역을 설정하고 K/B ratio를 구하여 비교하였다. $^{99m}Tc-DTPA$를 사용한 검사에서 370 Mbq을 사용하였을 때의 K/B ratio는 평균 $5.67{\pm}0.8$이었고, 185 Mbq을 사용하였을 때는 평균 $5.62{\pm}0.87$로 큰 차이를 보이지 않았다. $^{99m}Tc-MAG_3$를 사용한 검사에서도 신장/배후방사능 비는 370 Mbq을 사용 시 평균 $14.95{\pm}2.58$과 185 Mbq을 사용 시 평균 $14.56{\pm}2.02$로 큰 차이를 보이지 않았다. Paired sample t-test결과 p-value는 $^{99m}Tc-DTPA$ 0.566, $^{99m}Tc-MAG_3$ 0.363로 같은 비교집단 간 차이점이 없음을 확인하였다. 동일 환자를 대상으로 선량을 370 Mbq에서 185 Mbq로 줄였을 때의 동적신장검사의 재현성은 우수한 것으로 확인 되었다. 저선량 동적신장검사는 기존 감마카메라의 성능 개선 없이 재현성이 우수한 결과를 얻을 수 있고 환자의 피폭 또한 줄일 수 있을 것으로 사료된다.

Mesangial cell has several key roles in thee control of glomerular function: it partocipates in the regulation of glomerular filtration rate, macromolecular clearance, and as both a source and target of numerous hormones and autocrines. Many of these insights into mesangial cell function have been obtained by studying mesangial cells in culture. However, no suitble cell lines have established yet. We here reported the immortalization of rat kidney glomeruar mesangial cell by transfection of E6 and E7 genes of human papillomavirus type 16 (HPV-16) via electroporation and lipofection. The reslts showed that only electroporation could transfect the genes to mesangial cells and the transfected cells maintained the viability for longer than 6 months. Fluorescence microscopic observation showed that cellular contractility and phagocytosis, which are the two main phenotypes of mesangial cells with rat glomerular epithelial cells showed that the growth of mesangial dells was suppressed by epithelial cell, but the growth of epithelisl cells was enhanced by mesangial cells. Moreover, Such results may imply that the glomerular cell-cell interaction plays an important role in the regulation of cell proliferation and differentiation.

A 3-year-old male Maltese dog(weighing 2.5 kg) was referred with an excessive movement of mandible and depression. Comprehensive diagnostic investigation revealed an end-stage of renal disease with secondary hyperparathyroidism. The renal allograft was performed after the condition of dog was stabilized by hemodialysis and medical treatment. After transplantation, the renal function of this dog was returned to normal. thereafter, the dog died suddenly without apparent clinical signs. The subsequent pathological studies revealed the actual etiology of death was not clearly identified However acute pancreatitis caused by abrupt introduction of food after prolonged luting might be involved in the etiology. This case study showed the necessity of pancreatic function test in postoperative management after renal transplantation.

To investigate the effect of dietary Ca levels on metabolic changes of Ca and skeleton in postmenopausal women, 10-month-old ovariectomized female rats were compared with 2 month old rats. The rats were fed either 0.2% or 1.2% Ca diets for 16 weeks. Food intake and weight gain as higher in rats fed high Ca diets and in ovariectomized rats. Apparent Ca absorption as higher, and Ca balance was lower in the low Ca groups. Vertebrae density was higher in old rats or those fed a high Ca diets. The old rats and ovariectomized rats showed decreased bone formation, increased bone resorption and kidney function deterioration resulting in increased urinary Ca excretion. Contradictory to the above observation, old rats and ovariectomized rats still showed higher bone mass and bone ash content. Therefore aging was not fully onging in 10-month-old rats. Bone weights, mineral contents, and mineral/wt ratio were lower in ovariectomized rats. Dietary Ca level did not affect urinary Ca excretion, urinary protein excretion, GFR, serum alkaline phosphatase, or urinary hydroxyporline excretion. This means that dietary Ca level did not influence kidney function or bone turnover. However Ca content and the ash content of femur, 4th vertebra, and scapula were increased in high Ca groups. Therefore, it is considered that decreased bone formation and accelerated bone resorption may account for the increased osteoporotic risk in women in menopause after middle age. However, Ca metabolism can be improved and bone components can be maintained if Ca is supplemented.

The systolic and diastolic pressures in anesthetized Sprague-Dawley male rats were greatly decreased after single-dose of Cd treatment without significant changes in heart rate. There was a fluid-shift into the third space and/or -loss through the kidney, since plasma $Na^+$ concentration and hematocrit ratio were significantly increased by acute Cd exposure. The present study showed that the sustained hypotensive effect of single-dose Cd on the cardiovascular system might have resulted from the systemic hypovolemia. Furthermore, renal excretion of electrolytes, including $Na^+$ and $K^+$, and urine flow rate were increased by Cd intoxication. Interestingly, the ratio of $Na^+/K^+$ excretion was increased and reached the maximum level 3 hours after Cd injection and returned to the normal level after 7 hours. Nevertheless, there was no difference in the regression analysis of $Na^+$ excretion and urine flow rate in both groups. Therefore, the increase in the urine volume seemed to enhance the excretion of $Na^+$. This study strongly suggest that the hypotensive effect of Cd is mediated by systemic $Na^+$ loss through the kidney and/or hypovolemia via fluid-shift.

Captopril, angiotensin converting enzyme (ACE) inhibitor, when given intravenously in dog, elicited the diuretic action along with the increases of glomerular filtration rates (GFR), renal plasma flow (RPF) and osmolar clearances (Cosm) with no changes of free water clearnces ($C_{H_2O}$), and then captopril produced the enlargement of excretion rates of electrolytes in urine and the reduction of reabsorption rates of electrolytes in renal tubles. Captopril, when given into a renal artery, exhibited no changes of renal function in the experinental kidney, whereas diuretic action with the same mechanism as shown in intravenous captopril in control kidney. Captopril, when injected into a carotid artery, showed increases in rates of urine flow in a small does which did not affect on renal action when it was administered intravenusly. Diuretic action induced by captopril was not influenced by renal artery denervation, propranolol and angiotensin II inhibiters. Above results suggest that captopril produced diuretic action along with renal hemodynamic changes by slight contraction of vas efferense and reduction of reabsorption rate of electrolytes in renal tubules, especilly distal tubules, that may be mediatedby endogenous substances.

Present experiments were undertaken for the purpose of clarifying the effect of repeated halothane anesthesia on the liver and kidney function. Nine mongrel dogs were divided into three groups. The group one dogs were anesthesized once(control group) and the other two groups twice and trice respectively on 10th day of previous anesthesia experimental groups. Hematological examinations and blood chemical assays were undertaken during the period from one hour to 10 days after the anesthesia. From these experiments fellowing results were obtained; 1. No significant changes of erythrocyte count were recognized in both the control and experimental groups after the halothane anesthesia. 2. The total leukocyte counts of experimental groups showed significant decrease on one hour and subsequent increases after the anesthesia. 3. No significant changes were observed in SGOT, SGPT, ALP, BUN and serum glucose values in both the control and experimental groups. 4. The total serum protein values showed a tendency to decrease on the first hour of halothane anesthesia in both the control and experimental groups. From these results it may be concluded that the repeated halothane anesthesia done 10th day of previous anesthesia do not affect the liver and kidney function in dogs.
