We describe a case of a 61-year-old Korean man who was diagnosed with renal cell carcinoma that was discovered on abdominopelvic computed tomography obtained after the patient complained of back pain. A radical nephrectomy was performed, and the surgical specimen showed a relatively well-circumscribed and yellowish lobulated hard mass. Microscopically, the tumor showed sheets and nests of hypercellular pleomorphic cells with thick fibrous septation, frequent mitoses, and areas of adrenal cortical-like tissue. Immunohistochemical staining revealed that the tumor cells were positive for inhibin-${\alpha}$, vimentin, synaptophysin, and melan A. It also revealed that the tumor cells were negative for pan-cytokeratin, epithelial membrane antigen, paired box 8, ${\alpha}$-methylacyl-coenzyme A racemase, CD10, cytokeratin 7, carbonic anhydrase 9, c-Kit, renal cell carcinoma, transcription factor E3, human melanoma black 45, desmin, smooth muscle actin, S-100, chromogranin A, CD34, anaplastic lymphoma kinase, and integrase interactor 1. Based on these histopathological and immunohistochemical findings, we diagnosed the tumor as intrarenal adrenocortical carcinoma arising in an adrenal rest. Several cases of intrarenal adrenocortical carcinoma have been reported, although they are very rare. Due to its poor prognosis and common recurrence or metastasis, clinicians and pathologists must be aware of this entity.

Since renal failure causes decrease in tumor marker excretion, use of these markers in cancer care and treatment in patients with renal insufficiency or hemodialysis is controversial. The aim of this study was to investigate differences of serum levels of tumor markers CA15-3, AFP, CA19-9 and CEA in patients with impaired renal function. A total of 100 patients referred to the Tabriz Immam Reza and Amiralmomenin hospital from June 2010 to November 2011 were selected for study. Subjects were divided to 3 groups of healthy, dialysis and renal failure but non hemodialysis cases, the last category being re-grouped based on creatinine clearance. No significant relationship between different groups in serum levels of CEA (P=0.99) and CA19-9 (P=0.29) tumor markers was found. A significant correlation was observed between serum levels of AFP (P<0.001) and CA15-3 (P<0.001) and also a tendency between creatinine clearance and CEA (r=0.05, P=0.625). Creatinine clearance significantly correlated with AFP (P<0.001, r=0.53) and CA15-3 (p=0.00, r=-0.412), but not CA19-9 (P=0.089, r=-0.171). According to results of this study it appears that use of tumor markers in patients with impaired renal function should be performed with special precautions.

Human renal dipeptidase (RDPase) was purified from surgically removed kdneys of renal stone aptients by affinity chromatography using its specific inhibitor, cilastain, as the ligand. The partial purified RDPase of 6 mg exhivited specific activity of 99.4 unit/mg with 2, 029 fold purification. it was composed of a slow moving major band (96%) and a fast moving minor band (4%). The minor band was not a contaminant as it showed a dipeptidase-specific activity. The kinetic parameters determined with glycyldehydrophenylalanine (Gdp) as synthetic substrate were Vmax, $322.6\;\mu{mol/min/mg}$ and km, 0.120 mM. This experiment provided biochemical evidences that sugically removed, nonfunctional kidneys in respect of glomerular filtration still retained high activity of renal dipeptidase.

To evaluate the effect of Choakwiyeum(CKY) and Yukmijihwang-tang(YJT) water extract on the renal function and the levels of plasma aldosterone, this experiment was performed in the rabbbits. These result indicate that increase in urine volume(UV) after administration of CKY and YJT water extract is related to increase in glomerular filtration rate(GFR), free water clearance(FWC) and renal plasma f1ow(RPF) and also to decrease in plasma aldosterone concentration(PAC), which seems to be affected by renin-angiotensin-aldosterone system, and that reduced blood pressure seems to be caused by reduced peripheral resistance.

Twenty-one diabetic nephropathy patients with normal serum BUN(Blood Urea Nitrogen), creatinine levels and ten chronic renal failure patients with abnormal high BUN, creatinine levels were investigated to evaluate the renal function change after long term herb medicine administration. The hospitalized patients were administrated three times a day with herb medicine, which were prescribe frequently in practical oriental medicine such as many hospital and local clinics. Blood Urea Nitrogen, creatinine and glomerular filtration rate (GFR) were measured immediately after 7days medication. Serum BUN, creatinine levels in diabetic nephropathy patients changed from 17.63±4.38㎎/㎗, 1.09±0.26㎎/㎗(mean±SD) of pre-medication levels to 14.13±3.24 1,20±0.37, 14.75±2.21 1.23±0.55, 12.34±2.89 1.18±0.42 at 7th, 14th, 21th days after herb medicine administration respectively. Also 24hr urine total protein changed from 632.25±254.43㎎/㎗ of pre-medication levels to 623.18±231.56㎎/㎗ after herb medicine administration(P>0.05). Serum BUN, creatinine levels and GFR in chronic renal failure patients changed from 67.45±13.86㎎/㎗, 6.74±2.91㎎/㎗, 13.73±4.21㎖/min pre-medication levels to 61.23±17.75 6.43±2.29 15.49±3.56, 58.84±19.36 5.83±2.51 16.38±2.85, 56.39±20.33 5.64±2.52 16.73±3.40 at 7th, 14th, 21th days after herb medicine administration respectively. Therefore, there was not clinically remarkable difference in the serum BUN, creatinine, GFR levels between pre-medication and post-medication in both Group.

Diabetic Nephropathy is one of the major causes of chronic renal failure. It is a common microvascular complication and clinically defined as the presence of persistent Proteinuria. We studied the effects and change of the renal function of Complex Herbal medication of the 20Diabetic Nephropathy patients. We measured the initial levels of Total Protein, Creatinine Clearance Rate(Ccr), Serum Creatinine(Serum-Cr), Urine Creatinine(Urine-Cr) and HbA1C on admission and followed up the level changes of Total Protein, Ccr, Serum-Cr and Urine-Cr on discharge. The results are following : Complex Herbal Medication does not cause the renal toxicity. The longer hypertension period is, the higher Serum-Cr level and Urine-Cr level. In an older age group, Urine-Cr is lower. 4.From the 'Deficiency in Origin and Excess in Superficiality(本虛表實)'points of view, Complex Herbal Medication improves the Serum-Cr in Diabetic Nephropathy patients. According to this results, it could be suggested that Complex Herbal Medication does not cause the renal toxicity in Diabetic Nephropathy patients and intensive controls of blood sugar, blood pressure and Complex Herbal Medication prevent the renal failure in Diabetic Nephropathy patients with early stage of Microalbumiuria.

A 6-year-old castrated male Russian Blue cat was presented for evaluation of dyschezia. Abdominal ultrasound revealed hyperechoic nodules in both kidneys, heterogeneous mass in abdomen, and extensive mesenteric thickening with multiple hypoechoic nodules. Computed tomography showed multiple hypodense lesions in both kidneys and diffuse nodular infiltration around the mesentery. Fine needle aspirates (FNA) acquired under ultrasound guidance from the mesentery consisted of large lymphocytes which have round to irregular nuclei with granular chromatin, prominent nucleoli and a small amount of basophilic cytoplasm. Polymerase chain reaction (PCR) for antigen receptor gene rearrangement result of FNA sample revealed a T-cell malignancy. The cat died from acute renal failure after 1 cycle of modified Madison-Wisconsin L-CHOP protocol. Postmortem examination revealed bilaterally enlarged lumpy-bumpy shaped kidneys. Histopathologic examination showed an infiltration of malignant lymphocytes into the renal parenchyma and mesentery. Immunohistochemical staining of the renal sample displayed a negative expression of CD3, PAX5, MUM-1, and CD79. The clinical features and prognosis of the cat with renal lymphoma with mesenteric lymphomatosis have been described in this report.

Pumonary metastases from renal cell carcinoma are common, but metastases in the large brohchi are uncommon and recurrence of renal cell carcinoma 10 years after primary resection is rare case. When endobronchial metastasis do present they usually simulate, clinically and radiologically, bronchial carcinoma. We report a 67-year-old man with endobronchial metastasis of renal cell carcinoma 10 years after radical nephrectomy with a brief review of the literature.

The small pituitary mass was incidentally found in 40-years-old women with renal cell carcinoma. The endocrinological and ophthalmological evaluation revealed no deficit and the short-term follow-up was recommended. In 6 months later, the visual disturbance was reported and the size of mass was increased. The tumor was removed totally via the trans-sphenoid approach. The post-operative endocrinological insufficiency was not noticed. During one year of follow-up period, there was no evidence of recurrence without adjuvant radiotherapy. The clinical features of pituitary metastasis from renal cell carcinoma were similar to those of pituitary adenoma. The possibility of pituitary metastasis should be kept in mind in patients with sellar mass and renal cell carcinoma.
