The aim of this study is to clarify the therapeutic effect of hemodialysis (HD) on acute renal failure in dogs experimentally induced by ethylene glycol (EG) ingestion in experiment 1(HD on 12 and 36 hours after EG injestion) and experiment 2(HD on 24 and 48 hours after EG injestion). Clinical signs such as vomiting, depression, ataxia and knuckling were improved on experiment 1 and 2. White blood cell (WBC) and platelets (PLT) were decreased, and packed cell volume (PCV) was increased after hemodialysis, however, no significant differences were observed in experiment 1 and 2. BUN, creatinine and phosphorus was significantly decreased in experiment 1 and 2, respectively. These results suggested that hemodialysis was effective for acute renal failure in dogs induced by EG ingestion.

Ischemia/reperfusion injury, which is commonly seen in the field of renal surgery or transplantation, is a major cause of acute renal failure. Previous studies showed that antioxidant treatments attenuated renal ischemia/reperfusion injury. The objective of this study was to examine the role of hesperidin in modulating reactive oxygen species induced inflammation and apoptosis after renal ischemia/reperfusion injury. Rats were subjected to right nephrectomy, 15 days later 45 min of renal ischemia and 24 h reperfusion with or without treatment with hesperidin. Renal function, inflammation and apoptosis were compared at 24 h after reperfusion injury. Hesperidin improved the renal dysfunction and reduced inflammation and apoptosis after ischemia/reperfusion injury. In conclusion, hesperidin shows potent anti-apoptotic and antiinflammatory properties due to antioxidant property. These findings may have major implications in the treatment of human ischemic acute renal failure.

Rifampin is common drug to treat tuberculosis. Rifampin induced acute renal failure, hemolytic anemia and thrombocytopenia is rare and severe complication. We have experienced a case of rifampin induced acute renal failure, hemolytic anemia and thrombocytopenia. Forty-six years old male was suffered from reactivation of pulmonary tuberculosis, and had to medicate antituberculosis drugs including rifampin(600mg/day). Seven years ago, antituberdulosis medication were successfully administered to treat pulmonary tuberculosis without any side effects of drugs. But eight days after readministration of rifampin, fever, abdominal pain, vomiting, oliguria, elevated BUN and creatinine were developed. And thrombocytopenia was also identified after administration of rifampin. The patient was recovered slowly after discontinuation of rifampin & intensive medical care. The renal function was normalized at 55 days after cessation of rifampin. The renal pathologic findings were interstitial nephritis and acute tubular necrosis. And, the rifampin dependent antibodies were identified by indirect antiglobulin test in the presence of rifampin. So we report this case with a brief review of literature.

Objective : This study was undertaken to determine if Plantaginis Semen herbal acupuncture(PSA) has a protective effect on glycerol-induced acute renal failure in rats. Methods : Rats were dehydrated for 24hr and then injected with 4 ml/kg of 50% glycerol in each hindlimb muscle. In experiments for PSA effect, rats were received 0.1 ml of PSA extraction in both sides of corresponding $Sh\grave{e}nsh\bar{u}(BL_{23})$ of human body for 3 days after injection of glycerol. The experimental group were divided into the normal group, the control group, the sample 1,2,3 group. Results : Glycerol injection decreased glomerular filtration rate and increased urine volume, serum creatinine, BUN level and fractional excretion of $Na^+,\;K^+\;and\;Cl^-$. These results show that glycerol injection bring about acute renal failure. PSA significantly increased glomerular filtration rate and significantly decreased serum creatinine, BUN level and fractional excretion of $Na^+,\;and\;Cl^-$ as compared with control group. Conclusion : These results suggest that PSA can be used in prevention and treatment for acute renal failure. However, the precise mechanisms of PSA protection remain to be determined.

Endothelin-1 (ET-1) is unequivocally elevated in the kidney with ischemic acute renal failure (ARF), whereas ET receptors ($ET_AR$ and $ET_BR$) are variably expressed. Although renal functional and structural changes are similar between ischemic and nephrotoxic ARF, there are few reports on the alteration in the ET system in nephrotoxic ARF. This study was, therefore, undertaken to investigate changes in renal expression of ET-l and its receptors in nephrotoxic ARF induced by cisplatin. Mice were intraperitoneally injected with 16 mg of cisplatin/kg at a single dose, and the expression of mRNA and protein was then quantified by real-time RT-PCR and Western blot, respectively. Immunohistochemistry was conducted for localization. Three days after treatment, ET-1 transcript in cisplatin-treated mice was thirteen times higher than that in controls, whereas ET-1 peptide was increased by 1.5-fold. Cisplatin caused a 2-fold increase in the levels of ETAR mRNA and protein. Most of the increased immunoreactive ET-1 and ETAR were localized in damaged tubules. Neither the expression of ETBR mRNA nor the abundance and immunoreactive level of ETBR protein were changed. The findings suggest that the individual components of the renal ET system are differentially regulated in cisplatin-induced nephrotoxic ARF.

Phellinus linteus (Hymenocaetaceae) is a member of Basidiomycotinae, which has been used for the treatment of gastric cancer, non-insulin-dependent diabetes mellitus, diarrhea, and menstrual irregularity. To investigate the diuretic action of Phellinus linteus, urinary volume, serum parameters and urinary electrolytes in HgCl$_2$-induced acute renal failure rats in vivo were measured. The results showed that its MeOH extract produced significant increases on urinary volume, sodium and potassium excretion, and revealed lowering effects of the abnormally elevated BUN, creatinine and uric acid value in acute renal failure rats.

We studied the effects of the acute intermittent peritoneal dialysis in severe acute renal failure of 1 newborn infant and 2 young infants during 18 months period from February 1985 to April 1986. The predisposing illnesses were severe acute gastroenteritis with dehydration. Reye's syndrome, and bilateral nephrolithiasis with hyperuricemia. The concomittent illnesses were severe hypernatremia, hyponatremia, hyperkalemia, hypocalcemia, hypoglycemia, DIC(disseminated intravascular coagulopathy), paralytic ileus, metabolic acidosis and gastrointestinal bleeding. As a dialvsate, Imperinol $solution^R$, 1.5% was used in all cases. The cycles of dialysis were 8, 16, and 41 times in each cases. Observed complications during dialysis were leakage, and abdominal wall and scrotol swelling in 2 cases, hyperglycemia in 1 case, and peritonitis in 1 case. Acinetobacter calcoaceticus was cultured in peritoneal fluid of peritonitis. These complications were treated by stopping dialysis in leakage and abdiminal wall swelling, insulin therapy in hyperglycemia, and intraperitoneal and systemic antibiotics therapy in peritonitis. We experienced improvements of severe acute renal failure with variable concomittant illnesses by acute intermittent peritoneal dialysis despite of the treatable complications of dialysis in all cases.

신장은 독성물질, 빈혈, 재관류-유도 상해, 급성신부전에 회복 기능을 가지고 있다. 뇨 표피성장인자(EGF)는 신장 사구체연접장치에서 생산된다. 신장은 EGF를 축적하거나 배설한다. 신장 질환의 경우에는 EGF 배설이 감소한다. 본 연구에서는 glycerol-유도 급성신부전에서 스쿠알렌의 효과를 연구하였다. In vitro에서 RT-PCR를 통해 EGF 발현을 관찰하였다. 근위세뇨관 세포를 분리한 후, glycerol (1, 2, 4 mM) 혹은 스쿠알렌(0.1, 0.05 or 0.1%)을 첨가하였다. In vivo에서 BUN, creatine, 조직학적 변화를 관찰하였다. 실험군은 다음과 같다. 실험군 1은 정상군, 실험군 2는 glycerol (50%, 8 ml/kg) 처치 후, 스쿠알렌을 처치하지 않은 군, 실험군 3은 glycerol (50%, 8 ml/kg) 처치 후, 스쿠알렌(180 mg/kg)을 함께 처치한 군으로 각 실험군 당 생쥐 7마리를 사용하였다. 실험 결과, glycerol이 신장에 손상을 주어 EGF mRNA 발현이 감소됨을 확인할 수 있었다. 그러나, 스쿠알렌을 처치한 군에서는 EGF mRNA 발현이 증가함을 관찰할 수 있었다. 또한, BUN과 creatine 수치의 빠른 회복이 관찰되었다(P<0.01). 조직학적 관찰에서도 실험군 2는 사립체의 심한 손상이 관찰되었는데, 실험군 3의 경우 사립체의 빠른 회복이 관찰되었다. 결론적으로, 스쿠알렌이 glycerol-유도 급성신부전에 회복 효과가 있을 것으로 사료된다.

The efect of acute renal failure (ARF) on the pharmacokinetics o sulfobromophthalein (BSP) was investigated in order to elucidate if renal failure modifies the hepatic metabolism of drugs. ARF was induced by intravenous (iv) injection of uranyl nitrate (UN) to rats (5 mg/kg) five days before the experiment. Area under the plasma concentration-time curve (AUC)of BSP after portal vein (pv) injection increased by 2-fold and total body clearance ($CL_1$) decreased one half (p <0.01) in UN-induced ARF (UN-ARF) rate compared to the control rats. But the plasma disappearance of BSP after iv injection did not differ significantly between control and UN-ARF rats. Since BSP is excreted via the liver, $CL_1$ represented the approximate hepatic clearance of BSP. Therefore, the decrease in $CL_1$ represented the approximate hepatic clearance of BSP. Therefore, the decrease in $CL_1$ represents a decrease in hepatic intrinsic clearance ($CL_{int}$) for BSP since plasma free fraction ($f_p$) of BSP was not affected by UN-ARF. The content of hepatic cytoplasmic Y-protein, which catalyzes BSP-glutathione conjugation and limits the trasfer of BSP from blood to bile, increased significantly (p < 0.01), however its binding activity (BA) for BSP was decreased significantly (p <0.01) by UN-ARF. The decrease in $CL_{int}$might have some correlation with the changed characteristics of hepatic Y-protein, specifically its decreased BA for BSP.
