Herbal medicines are widely used to treat a variety of human diseases. However, therapeutic effect of herbal medicine on the canine facial nerve paralysis (FNP) has not been investigated. This study examined therapeutic effects of Oyaksungisan on the canine FNP. Ten dogs with the induced canine FNP were equally divided into the control and an herbal medicine-treated groups (5 dogs, Oyaksungisan-treated group), respectively. No treatment was given to the control group. In the Oyaksungisan-treated group, Oyaksungisan was administered orally, twice per day for 2 weeks (50 mg/kg) after inducing FNP. Significant differences in the clinical scores were detected between the Oyaksungisan-treated and control groups on day 14 (p < 0.05). The serum creatine kinase (CK) activities in the Oyaksungisan-treated group showed a tendency to decrease but there was no significant difference compared with those of the control group. In conclusion, Oyaksungisan was effective for the induced canine FNP.

Objectives : This experiments were performed to determine the effect of OYakSoonGi-San extract on hypertension in spontaneous hypertensive rat and norepinephrine-induced arterial contraction in rabbit. Methods : In order to define the effect of OYakSoonGi-San extract on contracted rabbit carotid arterial strips, transverse strips with intact or damaged endothelium were used for the experiment using organ bath. To analyze the mechanism of OYakSoonGi-San extract-induced relaxation, OYakSoonGi-San extract infused into contracted arterial strips induced by norepinephrine after treatment of indomethacin, $N{\omega}-nitro-L-arginine$, methylene blue or tetraethylammonium chloride. Results : Blood pressure was significantly decreased five days after administration of OYakSoonGi-San extract. The relaxation effect of OYakSoonGi-San extract was dependent on the presence of endothelium, showing that OYakSoonGi-San extract-induced relaxation was not observed in the strips without endothelium. Also OYakSoonGi-San extract-induced relaxation was significantly inhibited in arterial strips which were contracted by high $K^+$. OYakSoonGi-San extract-indeced relaxation was significantly inhibited by the pre-treatment of $N{\omega}-nitro-L-arginine$ or methylene blue, but it was not observed in the strips pre-treated with indomethacin or tetraethylammonium chloride. When additive application of $Ca^{2+}$ in arterial strips which were pre-contracted by norepinephrine in a $Ca^{2+}$-free solution, arterial contraction was increased. But contractile response to $Ca^{2+}$ was attenuated by pre-treatment of OYakSoonGi-San extract. Conclusions : These results demonstrated that OYakSoonGi-San could be applied effectively to hypertension and may inhibit agonist-induced contraction through an decrease influx of extra-cellular $Ca^{2+}$ by the formation of nitric oxide in the vascular endothelial cells.

Korean traditional prescription, Oyaksungisan was usually used to treat rheumatoid arthritis, paralysis. In this study, we compared the contents of five major components, ephedrine HCl, ferulic acid, hesperidin, 6-gingerol, glycyrrhizin and various unknown compounds in Ohyaksungisan (OY) with fermented Ohyaksungisan (FOY) by established HPLC-DAD method. The neuroprotective activity against glutamate-induced cytotoxicity in HT22 cell of OY and FOY was investigated by MTT assay. And anti-oxidative activity of OY and FOY was measured by DPPH radical, hydrogen peroxide and hydroxyl radical scavenging activity. After fermentation, contents of five major components and some unknown compounds (1), (2), (3) and (4) were increased in FOY. Also, FOY showed more potent neuroprotective activity. Furthermore, anti-oxidative activity of FOY was increased. In conclusion, the fermentation of OY could change contents various compounds and improved its neuroprotective activity.

Objectives : Oyaksungi-san(Wuyaoshunqisan) has been used for treatment of stroke and rheumatoid arthritis in Korea. In this study, a simple and accurate high-performance liquid chromatography(HPLC) method was established for simultaneous determination of six main components, liquiritin, ferulic acid, naringin, hesperidin, neohesperidin, and glycyrrhizin in Oyaksungi-san, a traditional Korean herbal prescription. Methods : The analytical column for separation of six constituents was used a Gemini $C_{18}$ column maintained at $40^{\circ}C$. The mobile phase consisted of two solvent systems, 1.0% (v/v) acetic acid in $H_2O$ (A) and 1.0% (v/v) acetic acid in acetonitrile (B) by gradient flow. The flow rate was 1.0 mL/min and the detector was a photodiode array (PDA) set at 254 nm for glycyrrhizin, 280 nm for liquiritin, naringin, hesperidin, and neohesperidin, and 320 nm for ferulic acid. Results : Calibration curves were acquired with $r^2$ values ${\geq}0.9998$. The results of recovery test were 91.58%-105.90% with a relative standard deviations (RSDs, %) value less than 2.0%. The values of RSD for intra- and inter-day precision were 0.03%-1.72% and 0.03%-1.63%, respectively. The contents of the six compounds in Oyaksungi-san were 0.33-9.30 mg/g. Conclusions : The newly established HPLC method will be helpful to improve quality control of Oyaksungi-san.

Objectives : This study was designed to evaluate the effects of Ohyaksungi-san(Wuyaoshungi-san) and Jungsongouhyul pharmacopuncture on pain reduction and nerve regeneration after crush injury in rat sciatic nerve. Methods : Animal model was produced through crush injury of right sciatic nerve and they were divided into four groups; Group I: no treatment control group; Group II: experimental group treated with Ohyaksungi-san(Wuyaoshungi-san); Group III: experimental group treated with Jungsongouhyul pharmacopuncture; Group IV: experimental group treated with Ohyaksungi-san(Wuyaoshungi-san) and Jungsongouhyul pharmacopuncture. For the assessment of pain, this study was observed the paw withdrawal latency(PWL) and immunoreactivity on the substance-P. For the assessment of nerve regeneration, the sciatic functional index(SFI) and immunoreactivity on the BDNF were measured. Results : 1. In the assessment of pain, the PWL of experimental groups was significantly higher than control group and group IV was significantly higher than other groups at the all days. 2. In immunohistochemical response of substance-P, as time passes, the immunoreactivity of all groups were decreased gradully. Especially, group IV had the lowest immunoreactivity. 3. In the assessment of SFI, the SFI of experimental groups were significantly higher than control group. 4. In immunohistochemical response of BDNF, the BDNF immunoreactivity of all groups was significantly higher than control group and especially, group IV had the highest immunoreactivity at the 14 days after injury. 5. H & E stain was used on the liver and kidney to investigate toxic effect of Jungsongouhyul pharmacopuncture and Ohyaksungi-san(Wuyaoshungi-san) on on 21 days after injury. However there were no any toxic effects both control group and experimental groups. Conclusions : On the basis of these results, we propose that Ohyaksungi-san(Wuyaoshungi-san) and Jungsongouhyul pharmacopuncture were related to pain reduction and motor nerve recovery, also decreased substance-P expression and increased BDNF expression after crush injury of sciatic nerve, especially these two treatments could be more effective when they were combined simultaneously.
