  • 1. Objective : The present author have examined the comparative effects of Hyeongbangjihwang-tang and Sibimikwanjung-tang in glycerol-induced acute renal failure, a model for myoglobinuric acute renal failure. 2. Methods : Above two prescriptions were applied to rat ad libitum and serum level of creatinine, glucose and blood urea nitrogen(BUN) were measured. And serum level of $Na^+$, $K^+$ and $Cl^-$, too. 50%(vol/vol) glycerol at a dose of 10 ml/kg of rat body weight intramuscularly and 1% concentration of prescriptions were applied to rats for 7 days ad libitum. 3. Results : Serum level of creatinine and $K^+$ significantly increased by glycerol injection, and these showed pre-renal and renal cause of acute renal failure. Hyeongbangjihwang-tang administered group showed decreasing tendency on serum level of creatinine when compared with control groups, but not significant. Sibimikwanjung-tang administered group showed significant increase of serum level of BUN when compared with control groups. 4. Conclusions : Above two prescriptions showed no significant changes on glycerol induced acute renal failure, but Hyeongbangjihwang-tang and Sibimikwanjung-tang showed a little different manner of response.

  • This study was carried out to determine if Salviae Radix extract (SRE) exerts protective effect against alterations in membrane transport function in rabbits with rhabdomyo lysis-induced acute renal failure. Acute renal failure was induced by intramuscular administration of glycerol (50%, 10 ml/kg). GFR in the glycerol-injected animals was reduced to 11% of the basal value and the fractional $Na^{+}$ excretion was increased to 7.8-fold, indicating generation of acute renal failure. When animals received SRE pretreatment for 7 days prior to glycerol injection, such changes were significantly attenuated. The fractional excretion of glucose and phosphate was increased more than 43-fold and 27-fold, respectively, in rabbits treated with glycerol alone. However, they were increased to 17-and 4.3-fold, respectively, in SRE-pretreated rabbits, and these values were significantly lower than those in rabbits treated with glycerol alone. Uptakes of glucose and phosphate in purified isolated brush-border membrane, the $Na^{+}-K^{+}-ATPase$ activity in microsomal fraction, and cellular ATP levels all were reduced in rabbits treated with glycerol alone. Such changes were prevented by SRE pretreatment. Uptakes of organic ions, PAH and TEA, in renal cortical slices were inhibited by the administration of glycerol, which was prevented by SRE pretreatment. Pretreatment of an antioxidant DPPD significantly attenuated the increase in the fractional excretion of glucose and phosphate induced by rhabdomyolysis. These results indicate that rhabdomyolysis causesimpairment inreabsorption of solutes in the proximal tubule via the generation of reactive oxygen species, and SRE pretreatment may provide the protection against the rhabdomyolysis-induced impairment by its antioxidant action.
