Background: Samul-tang (Si-Wu-Tang, SMT) is a traditional herbal formula, which has been widely used to treat various diseases such as menstrual irregularity, bleeding and leucorrhea. Although many studies have investigated the pharmacological properties of SMT, its toxicity information has not yet been fully elucidated. Methods: Five Sprague Dawley (SD) rats of each sex were given a single dose (5000 mg/kg) of SMT by gavage; control rats received the vehicle only. After the single administration, mortality, clinical signs, body weight changes and gross findings were monitored for 15 days in accordance with Good Laboratory Practice (GLP) principles. Results: In a single oral dose toxicity study, there was no adverse effect on mortality, clinical sign, body weight change or gross finding in any treatment group. Conclusions: The results indicate that SMT did not induce toxic effects at a dose level up to 5000 mg/kg in rats and its median lethal dose ($LD_{50}$) was considered to be over 5000 mg/kg/day body weight for both genders.

This study was designed to investigate the effects of Samul-tang Extract and Bambusae caulis in liquamen(SEB) on the changes in regional cerebral blood flow (rCBF) and mean arterial blood pressure (MABP) in normal rats. The results were as follows ; SBE significantly increased rCBF in a dose-dependent manner, and increased MABP in a dose-dependent manner. This result suggests that SBE significantly increased rCBF by dilating pial arterial diameter. Increase of SBE-induced rCBF was significantly inhibited by pretreatment with indomethacin (1 mg/kg, i.p.), an inhibitor of cyclooxygenase and increase of SBE-induced rCBF was inhibited by pretreatment with methylene blue ($10\;{\mu}g/kg$, i.p.), an inhibitor of guanylate cyclase. Increase of SBE-induced MABP was significantly increased by pretreatment with methylene blue but increase of SBE-induced MABP was decreased by pretreatment with indomethacin. These results suggested that the action of SBE was mediated by cyclooxygenase.

In oriental medicine, Samul-tang (SMT) has been used for the treatment of cardiovascular diseases and neuronal disorders. Here, possible effects of SMT on axonal regeneration after the spinal cord injury were examined. SMT treatment induced increases in regeneration-related proteins GAP-43, cell division cycle 2 (Cdc2) and phospho-Erk1/2 in the peripheral sciatic nerves after crush injury. Increased levels of Cdc2 and phospho-Erk1/2 were observe mostly in the gray matter area and some in the dorsomedial white matter. These increases correlated with increased cell numbers in affected areas. Moreover, axons of corticospinal tract (CST) showed increased sprouting in the injured spinal cord when administrated with SMT compared with saline-treated control. Thus, the present data indicate that SMT may be useful for identifying active components and for therapeutic application toward the treatment of spinal cord disorders after injury.

Objectives: We performed simultaneous determination of five constituents by HPLC in Samul-tang (SMT). Additionally, we investigated the immune-stimulatory potential of SMT on specific cellular and humoral immune responses in ovalbumin (OVA)-immunized mice. Methods: Reverse-phase chromatography using a Gemini C18 column operating at $40^{\circ}C$, and photodiode array (PDA) detection at 190-400 nm, were used for quantification of the five components of SMT. Mobile phase using a gradient flow consisted of two solvent systems. Solvent A was 1.0% (v/v) aqueous acetic acid and solvent B was acetonitrile with 1.0% (v/v) acetic acid. C57BL/6 mice were immunized intraperitoneally with OVA/alum ($100{\mu}g/200{\mu}g$) on days 1, 8, and 15. The extract of SMT (1000 mg/kg) was given to mice orally for 21 days (from day 1 to day 21). At day 22, OVA-, lipopolysaccharide (LPS)- and concanavalin A (Con A)-stimulated splenocyte proliferation and OVA-specific and total antibodies were measured in plasma. Results: Calibration curves were acquired with $r^2$>0.9999, and the relative standard deviation (RSD, %) for intra- and inter-day precision were both less than 3.5%. The recovery was in the range of 95.69-115.12%, with an RSD less than 6.0%. The contents of five components in SMT were 1.08-15.30 mg/g. SMT significantly enhanced Con A-induced splenocyte proliferation in OVA-immunized mice (p<0.01). Also, SMT significantly enhanced OVAspecific IgG, IgG1 and total IgM levels in plasma compared with the OVA-immunized group. Conclusions: The established method will be applied for the quantification of major components and immunestimulating activity in OVA-immunized mouse model of SMT.

Samul-tang (SMT), which was firstly described in (Hwajegukbang) Song dynasty, is well known remedy for blood diseases in Oriental medicine. SMT is traditional herbal-remedy composed of Rehmanniae Radix Preparat, Angelicae Gigantis Radix, Cnidii Rhizoma and Paeoniae Radix. Recently, SMT has known to have anti-oxidative action. However, the reports on anti-oxidantic action in neuroglial cells are rare. In addition, the exact mechanisms are unclear. For these reasons, we investigated the protective effects of SMT on cell death induced by oxidative stress using C6 glioma cells. In our results, SMT accelerated proliferation rates of C6 cells in vitro. In addition, levels of LDH release induced by oxidative stress were lowered by treatment with SMT. Finally, protective effects on cell death induced by chemicals such as paraquat and rotenone were observed. In conclusion, these results suggest the possibility to protect brain cell or neuronal cell from damage induced by oxidative stress.

Objectives : This study was designed to investigate the protective mechanisms of Samul-tang (SMT) on $H_2O_2$-induced toxicity in H9c2 cardiomyoblast cells. Methods : The cultured cells were pretreated with SMT and exposed to $H_2O_2$. The cell damage was assessed by using MTT assay. Also, we used Hoechst staining, Western blotting analysis. Results : SMT significantly reduced both $H_2O_2$-induced cell death and chromatin fragmentation. The decrease of Bcl2 expression by $H_2O_2$ was inhibited by SMT. In addition, the increase of Bax expression was also inhibited by SMT. In particular, Fas expression, which is generally recognized as cell death inducing signal by Fas/FasL interaction, was markedly decreased by $H_2O_2$ in a time-dependent manner, whereas this decrease was completely prevented by SMT. The cotreatment of SMT and $H_2O_2$ in H9c2 cells also induced the phosphorylation of ERK in a time-dependent manner. Moreover, PD098059, a specific inhibitor of ERKl/2, attenuated the protective effect of SMT on $H_2O_2$-induced toxicity in H9c2 cardiomyoblast cells. Furthermore, the protective effect of SMT was significantly blocked by treatment of SB203580, a specific inhibitor of p38. Conclusions : Taken together, this study suggests that the protective effects of the water extract of SMT against oxidative damages may be mediated by the modulation of Bel2 and Bax expression via the regulation of ERK and p38 signaling pathway.

Samul-Tang (SMT) has been used for nourishing of the blood, hematopoiesis as a herbal medicine history. The purpose of this study is to find out anti-allergic inflammatory reaction of SMT. To clarify the mechanism, the effect of SMT on vascular permeability of rat cutaneous tissue and histamine and cytokines (IL-6, IL-8, TNF-${\alpha}$) release from mast cells were observed. The results are the pretreatment with SMT significantly decreased the compound 48/80-induced degranulation and histamine release from RPMC, SMT also inhibited the anti-DNP lgE-induced increment of vascular permeability of rat cutaneous tissue. SMT significantly reduced the PMA plus A23187-induced increment of expression of IL-6, IL-8, and TNF-${\alpha}$ in HMC-1 Cell. The Present study provide evidence that SMT inhibits mast cell-derived inflammatory allergic reactions by blocking histamine release and pro-inflammatory cytokine expression, and suggest the mechanisms of action. Furthermore, in vivo and in vitro anti-allergic effect of SMT suggests a possible therapeutic application of this agent in inflammatory allergic diseases.

Objective: Many types of delayed adverse reactions, such as long-term numbness, occur after injecting contrast medium, but few clinical studies have reported effective treatments for these reactions. We report that herbal medicine can have a positive clinical effect in patients who have experienced long-term numbness after contrast medium injection. Method: A patient who had felt numbness in her head and whole limbs presented at Semyung University Korean Medicine hospital. Her numbness had first started 2 days after injection of contrast medium, and she had felt it constantly for almost 2 years. After admission at the hospital, she took "modified Samul-tang" herbal medicine (120 cc three times per day) from 29 January 2019 to 2 February 2019. We measured her numbness using a numeric rating scale (NRS) on 29 January and 2 February and we compared both scores to determine the degree of favorable and clinical effects of herbal medicine. Result: The NRS score for numbness was 5 for her head and limbs on the first day (29 January), but after 4 days (2 February), the NRS score decreased to 0 for her head and both arms and hands, and it decreased from 5 to 2 for both her legs and feet. Conclusion: Korean herbal medicine can have positive clinical effects on treating adverse reactions due to injection of contrast medium.
