The renoprotective activities of white ginseng radix and rootlet were compared in spontaneously hypertensive rat (SHR) with diabetes. During oral administration of white ginseng radix (Ginseng Radix Alba, GRA) and white ginseng rootlet (Ginseng Radix Palva, GRP) for four weeks, arterial blood pressure and blood glucose levels were determined at every 10 days. In both GRA- and GRP-treatment groups, arterial blood pressures started to go down after 10 days of administration and maintained throughout the study period. After four weeks administrations of GRA and GRP, diastolic blood pressures were significantly decreased with 17% and 9%, respectively. GRA treatment also decreased blood glucose levels after 10 days of administration when compared with diabetic SHR group. At the end of the experiment, serum creatinine (Scr) and blood urea nitrogen (BUN) were not significantly different between the groups, except 62% higher value of BUN in diabetic SHR group when compared with SHR group. In the diabetic SHR group, the excretion of urinary albumin was increased significantly when compared with SHR. The level of urinary albumin in GRA treated group was markedly reduced when compared with diabetic SHR group $(67.8{\pm}4.7\;vs.\;131.3{\pm}13.5\;mg/24\;h).$ To examine the effects of ginseng radices on an overt diabetic nephropathy, index of kidney hypertrophy and transforming growth $factor-{\beta}1\;(TGF-{\beta}1)$ protein levels were evaluated. The glomerular and tubular cells stained positive for $TGF-{\beta}1$ seemed to be more abundant in diabetic SHR than in those with SHR, and GRA treated rats showed somewhat less $TGF-{\beta}1$ protein in glomerular and tubular cells when compared with diabetic SHR. Our results suggest that GRA might be a useful antihypertensive and antidiabetic agent with renoprotective effect.

Objectives : The purpose of the present study is to evaluate the effects of herbal acupuncture with Ginseng Radix for the treatment to intestinal disease in the rat with 2, 4, 6-trinitrobenzenesulfonic acid (TNBS) induced colitis. Methods : All animals were subjected to the injection of saline $(300{\mu}{\ell},\;500{\mu}{\ell})$ for a study control or TNBS $(300{\mu}{\ell},\;500{\mu}{\ell})$ into the lumen of the colon, 8cm proximal to the anus through the intestine. Ginseng Radix herbal acupuncture ($20mg/m{\ell},\;0.4m{\ell}$) were injected to the both $Hapgok(LI_4)$ acupoints at 2nd injection of TNBS in rats. Thus, the body weight, RBC count, WBC count, total protein, IgG levels and IgM levels were observed to study the effects of Ginseng Radix herbal acupuncture. Results : Ginseng Radix herbal acupuncture on $Hapgok(LI_4)$ for TNBS-induced colitis inhibited the body weight loss rate but did not affect RBC and WBC counts. Furthermore, it inhibited the reduction of total protein concentration and serum IgG and IgM levels in TNBS induced colitis were recovered. Conclusions : Herbal acupuncture with Ginseng Radix helps recover the TNBS-induced colonic damage and may be an important method for treatment of the colitis.

This paper presents a high-throughput area-efficient mixed-radix fast Fourier transform (FFT) processor using the efficient scheduling schemes. The proposed FFT processor can support 64, 128, 256, and 512-point FFTs for orthogonal frequency division multiplexing (OFDM) systems, and can achieve a high throughput using mixed-radix algorithm and eight-parallel multipath delay commutator (MDC) architecture. This paper proposes new scheduling schemes to reduce the size of read-only memories (ROMs) and complex constant multipliers without increasing delay elements and computation cycles; thus, reducing the hardware complexity further. The proposed mixed-radix MDC FFT processor is designed and implemented using the Samsung 65nm complementary metal-oxide semiconductor (CMOS) technology. The experimental result shows that the area of the proposed FFT processor is 0.36 mm2. Furthermore, the proposed processor can achieve high throughput rates of up to 2.64 GSample/s at 330 MHz.

Objectives : Achyranthes bidentata radix (Usul) has been used as anti-arthritic, antiallergic, antidiuretic, and so on. Recently extracts of Achyranthes bidentata radix have shown anti-inflammatory and cancer preventive effects in vitro and in vivo. Methods : We therefore evaluated the inhibitory potential of ethanol extracts of Achyranthes bidentata radix on cytochrome P450 (CYP) isoforms-catalyzed reactions, which relate to causes of cancer and inflammation, including CYP1A2, CYP2C9, CYP2C19, CYP2E1, CYP2D6, CYP2C8, and CYP3A4, using human liver microsomal preparations. Results : The extracts showed weak or negligible inhibitory effects on CYP2C9-catalyzed (S)-warfarin 7-hydroxylation, CYP2C19-catalyzed S-mephenytoin 4-hydroxylation, and CYP2D6-catalyzed dextromethorphan O-demethylation with each IC50 over 1750 g/ml, respectively. However, it showed relatively significant inhibitory effect on CYP1A2-catalyzed phenacetin O-deethylation and CYP2E1-catalyzed chlorzoxazone 6-hydroxylation with IC50s of 970.5 g/ml and 821.4 g/ml, respectively. Conclusions : These results suggest that extracts of Achyranthes bidentata radix have inhibitory effects on CYP-catalyzed reactions, especiallyCYP1A2 and CYP2E1, in human liver microsomes. These effects appear to relate to anti-inflammatory and cancer prevention following decrease of reactive oxygen species formed by CYP, especially CYP1A2 and CYP2E1, by Achyranthes bidentata radix. However, further evaluation is necessary to demonstrate and to confirm its effects in human.

Salvia miltiorrhiza Radix is cultivated in Korea and China and is traditionally used to treat cardiovascular diseases. In this study, we developed and validated a quantitative analysis method for S. miltiorrhiza Radix using high-performance liquid chromatography (HPLC). Identification was performed using ultra performance liquid chromatography-tandem mass spectrometry. For quantitative analysis, we used seven marker compounds. Separation conditions for HPLC were optimized using an ODS column with gradient conditions of 1% formic acid in distilled water and 1% formic acid in acetonitrile, with a flow rate of 0.8 mL/min and a detection wavelength of 280 nm. This method showed good linearity ($R^2=0.9998$), precision (relative standard deviation ${\leq}3.3%$), accuracy (recovery of 94.16-102.89%), limit of detection ($7.53{\mu}g/mL$), and limit of quantification ($23.71{\mu}g/mL$). This approach successfully quantified marker compounds in S. miltiorrhiza Radix. The individual marker compounds were identified by comparing the molecular masses and retention times with does standard compounds. Marker compound contents of S. miltiorrhiza Radix were investigated with different cultivation regions. Seven marker compounds were detected and quantified in all samples. Among them, salvianolic acid B showed the highest contents and it ranged from 4.13 to 7.15%. The salvianolic acid B content (7.15%) of marker compound was the highest in Bonghwa, and the tanshinone IIA content (1.90%) was the highest in Pohang. The results of marker compounds and developed method were intended to provide a favorable reference for the study of S. miltiorrhiza Radix from different regions of Korea.
