Medicinal plant Rehmanniae Radix has long been used as traditional herbal medicine in Korea. In this study, we investigated quantitative changes of marker substance 5-hydroxymethyl-2-furaldehyde (5-HMF) in Rehmanniae Radix Preparata fermented with Ganoderma lucidum, Paecilomyces japonica, honey, and Nuruk, using HPLC according to the Korean Pharmacopoeia. As a result, 5-HMF was decreased in SDT and SYT, and increased in SST and SNT, comparing with control group. Quantitative increasing of 5-HMF is not exactly in direct proportion with fermentation, and it is need further studies to elucidate mechanism of quantitative changes by converted and newly produced substances with fermentation.

Rehmanniae Radix Preparata attributes good blood circulation and it has been used for the treatment of dizziness, men's sterility, excessive loss of blood and weakness. On the quality control of the commercial Rehmanniae Radix Preparata, quantitative determination of 5-hydroxymethyl-2-furaldehyde (5-HMF) using HPLC method has been conducted. Quantitative analysis of 5-HMF in Rehmanniae Radix Preparata showered average 0.121${\pm}$0.063% in 14 samples collected throughout the regions of Korea. Contents of loss on drying, residue on ignition and residue on acid insoluble ignition showered average 14.084${\pm}$2.804%, 3.415${\pm}$0.790% and 0.807${\pm}$0.474% respectively.

Physiological effects in SAM P6 and Rl by administration of Cervus cornu, Astragali Radix, Rehmanniae Radix, and Angelicae Radix extracts were screened to know in vivo activities of each extracts. We measured complete blood cells (CBC) such as aBC, HGB, and HCT using coulter's method. Plasma concentrations of albumin, glucose, alkaline phosphatase, calcium, creatinine, inorganic phosphate, urea and total iron ere also analyzed using biochemical clinical autoanalyzer. Plasma concentrations of cortisol, total T$_3$, and total T$_4$ were measured by chemiluminescent immunoassay methods. At 12 weeks after birth, Cervus conu or Astragali Radix or Rehmanniae Radix extracts were given 5 g/Kg.day p.o. for 0,7,14,21, and 30 days each in both SAM Rl and SAM P6. Angelicae Radix study was done the same as the others except the mice were 16 weeks after birth. The RBC, HGB, and HCT levels after administration of Astragali and Rehmanniae were elevated in SAM Rl, but those in Cervi study were increased in SAM P6 the most. Decreases in alkaline phosphatase concentration of SAM Rl and P6 after Cervi administration were detected. Total plasma iron concentration was decreased by Angelicae administration in SAM P6. In general, Angelicae and Rehmanniae stimulate increases in cortisol, but total T$_3$ and T$_4$ levels were also elevated by all these extracts. In conclusion, these herval medicine extracts help hematopoiesis in SAMs through probably different mechanisms.

Background: Rehmanniae radix preparata is a medicinal herb widely used in Asian countries, to replenish Yin and Vital Essence through strengthen the kidney function. In Oriental Medicine the brain has physiological relationship with the Vital Essence. And central nerve system (CNS) is also refered to as 'Sea of the Vital Essence'. So if the Vital Essence is strong it will nourish the brain and memory will all be keen. The purpose of this study was to investigate the effect of 7 to 14 days treatment with Rehmanniae radix preparata (3.4 g /100 g, per os) on retention performance of rats in a passive avoidance situation. Methods: Male Sprague-Dawley rats were trained on a one-trial passive avoidance task using a two-way shuttle box by giving a foot shock. They were tested for retention of 6h, 24h, 72h, 168h, and 336h after training. Results: Rehmanniae radix preparata treated rats showed a increased performance in retention test as compared to saline at 6hr (P<0.05) and 24hr (P<0.05). Conclusion: These data suggest that Rehmanniae radix preparata treatment can improve memory in the rat.

Objective : The 5-HMF was not index material suitable to do the quality control of Rehmanniae Radix Preparata. In this study, We estimated the changes of oligosaccharide contents in Rehmanniae Radix Preparata using high-performance anion-exchange chromatography with pulsed amperometric detection(HPAEC-PAD). Methods : The analysis of oligosaccharide was conducted by HPAEC-PAD with Carbopac PA1, $250{\times}4mm$, 5um, and Carbopac PA1 guard column. Column temperature was kept at $30^{\circ}C$. Elution was carried out at 1000 ${\mu}l/min$ with 70mM NaOH and the injection volume was $10{\mu}l$. Each component was detected by PAD. Results : Nine constituents were found from merchandising Rehmanniae Radix Preparata(MR), while seven constituents were found in various processed Rehmanniae Radix Preparata. Not all constituents were defined but stachyose and raffinose were found in all cases. And The most common constituents of Rehmanniae radix was stachyose. In the course of processing, most of stachyose and raffinose were decreased. Stachyose was decreased slowly in the course of processing with rice wine(RR), amomi and rice wine(AR), and crataegi and rice wine(CR). However stachyose was decreased rapidly in the course of processing with fresh rehmannia juice(FR). The method with crataegi and rice wine(CR) showed the smallest decrease of stachyose. And processing method with crataegi and rice wine(CR) showed the most abundant amount for stachyose after the nineth processing. Conclusion : The changes of oligosaccharides in the course of processing were a very important direct barometers to do the quality control and set up a standard of Rehmanniae Radix Preparata.

One of the major side effects of cisplatin is nephrotoxicity, leading to acute renal failure. Recent study has suggested a role of hydroxyl radicals and p53 in renal cell injury by cisplatin. This study determined the possible involvement of oxidative stress in p53 activation. In rat mesangial cells, cisplatin treatment induced apoptosis and p53 activation. Pifithrin-$\alpha$, a pharmacological inhibitor of p53, suppressed cisplatin-induced apoptosis. Cisplatin also induced reactive oxidative species (ROS) generation. Of interest, cisplatin-induced apoptosis was prevented by N-acetyl-cysteine (NAC), a general antioxidant. NAC diminished p53 activation during cisplatin treatment. Puerariae Radix and Rehmanniae Radix Preparata with antioxidative activity were reduced the cisplatin-induced ROS generation, caspase-3 activity and p53 activation. In conclusion, ROS may contribute to p53 activation to initiate cisplatin-induced apoptosis in rat mesangial cells. In result, antioxidative effect of Puerariae Radix and Rehmanniae Radix Preparata prevented cisplatin-induced apoptosis through inhibition of p53 activation.

Objectives: The present study was carried out to investigate the preventive effects of Samgijiwhang-Tang(SJT) on streptozotocin(STZ)-induced diabetic nephropathy. Methods: SIT was given to rats through oral administration. The experimental animals were divided into a normal group of rats, a control group of STZ-induced diabetic rats, and a sample group with SIT administration. Rehmanniae Radix Preparat is combined in the original prescription of SIT, but in this experiment, Rehmanniae Radix was combined instead of Rehmanniae Radix Preparat to compare the effects of anti-diabetic nephropathy. Experimental diabetic nephropathy was induced by the injection of STZ(60mg/kg) in the rat via the peritoneum. The effect of SIT on STZ-induced diabetic nephropathy was observed by measuring the serum level of creatinine and BUN, in addition to urine secretion of albumin for 24 hours and the level of glucose found in the urine. Anti-oxidative stress of SIT administration in a living body was estimated by measuring lipid peroxide and GSH content in the cortex of kidneys. Results: STZ induced an increase of serum creatinine, urine glucose and renal cortical lipid peroxidation was lowered by Rehmanniae Radix Preparat combined SIT administration. Conclusions: The SIT treatment showed a protective effect on the rat diabetic nephropathy model, and action mechanism of the effect was thought to be concerned with anti-oxidative stress.

In order to determine the content of 5-hydroxymethyl-2-furaldehyde (5-HMF) in the Rehmanniae Radix Preparata, 5-HMF was isolated from the EtOAc fraction of the Rehmanniae Radix Preparata samples and identified by spectroscopic and physicochemical evidences. Twenty one samples prepared on the basis of increasing number of stewing times with wine were analyzed by HPLC. From this analysis, it was revealed that the samples processed under one to nine times of stewing showed increasing pattern in 5-HMF contents. And the samples processed under 9 to 18 times of stewing showed 0.53-0.74% in 5-HMF contents. However, for those samples processed more than 19 times, 5-HMF content profile showed decreasing pattern.
