Sagunja-tang(Sijunzi-tang) has been traditionally prescribed as a restorative. The present study was undertaken to determine the possible toxic effects of Sagunja-tang on SD rats. In this study, we investigated the subacute toxicity of water-extracted Sagunja-tang(Sijunzi-tang) on SD rats. Twenty rats were orally adiministered Sagunja-tang for 28 days at a dose of 0 mg/kg(control group) or 1500mg/kg(treated group), respectively. All of subjects was survived. No significant difference in abnormal clinical signs, related to hematological values, serum biochemical values, water and feed intake, coagulation time, autopsy analysis, organ weight, tissue microscopically, funduscopy, urine intake and urinalysis, was detected. Compared with the control group, we could not find any subacute toxic alteration in treated group (1500mg/kg) for 28 days. This result suggests that Sagunja-tang(Sijunzi-tang). a herbal medicine prescription, is a safe prescription to body.

The spleen is the source of gi, blood, body fluid and plays a vital role in maintaining life. The function of the spleen is to transform food nutrients and water, and to transport them to the heart and the lung. The movement of splenic gi is marked by elevation. The spleen governs the activity of elevating the lucid. The function of transportation and transformation is usually disturbed in the state of Gi deficiency of the spleen. The main clinical manifestations of gi deficiency of the spleen can be divided into as followers: anorexia, loose stool if the digesting and absorbing functions are disturbed; phlegm and edema if dampness and water are retained due to unhealthy water metabolism. Sagunja-tang can be applied for gi deficiency syndrome of the spleen. Ingredient bakchul(Rhizoma Atractylodis Macrocephalae) and bokryeung(Poria) can be used as monarch drug to eliminate dampness and strengthen the spleen.

Objectives : The present study aimed to find out the effect of Sagunja-tang on the prevention and treatment of inflammatory bowel disease using mice with TNBS-induced inflammatory bowel disease. Methods : Mice with TNBS-induced inflammatory bowel disease were medicated with Sagunja-tang, and the weight changes, colon length, lipid peroxidation, and myeloperoxidase activity were observed. Levels of the inflammatory markers interleukin (IL)-$1{\beta}$ and cyclooxygenase-2 (COX-2), its transcription factor activation, phospho-NF-${\kappa}$B (pp65), in the colon by enzyme-linked immunosorbent assay and immunoblot analysis were also measured. Finally, the activation of fecal bacterial enzyme, ${\beta}$-glucuronidase and degradation activation of fecal glycosaminoglycan (GAG) and hyaluronic acid were observed. Results : We found that oral administration of Sagunja-tang inhibited TNBS-induced colon shortening and also inhibited myeloperoxidase activity in the colon of mice as well as IL-$1{\beta}$ and COX-2 expression. Sagunja-tang also inhibited TNBSinduced lipid peroxidation and pp65 activation in the colon of mice. In addition, Sagunja-tang inhibited ${\beta}$-glucuronidase activation and fecal hyaluronic acid degradation activation. Conclusions : It is supposed that Sagunja-tang has a potential therapeutic effect on inflammatory bowel disease through the inhibition of both NF-${\kappa}$B activation and lipid peroxidation, and the improvement of intestinal conditions.

Objectives : Sagunja-Tang is a famous prescription used in Korean medicine for the purpose of promoting vital energy, and there are few studies using Sagunja-Tang on cerebrovascular diseases yet. As previous studies confirmed that Sagunja-tang is highly likely to be used effectively for stroke, this study was intended to predict the mechanism through which Sagunja-tang would act effectively on stroke. Methods : In this study, a network pharmacology analysis method was used, and oral bioavailability (OB), drug likeness (DL), Caco-2 and BBB permeability were utilized to select compounds with potential activity. For the values of each variable used in this study, OB ≥ 30%, DL ≥ 0.18, Caco-2 ≥ 0, and BBB ≥ 0.3 were applied. Using the above variables, the relations between target genes and diseases that are presumed to be involved in the selected bioavailable compounds were constructed in a network format, and proteins thought to play a major role were identified. Results : Among the compounds included in Sagunja-Tang, 26 bioavailable compounds were selected and it was confirmed that these compounds can be effectively used in cerebrovascular diseases such as Alzheimer's disease and stroke. These compounds are considered to act on proteins related in cell death and growth. The most important mechanism of action was predicted to be apoptosis, and the protein that is thought to play the most key action in this mechanism was caspase-3. Conclusions : In our future study, Sagunja-Tang will be used in an ischemic stroke mouse model, and the mechanism of action will be explored focusing on apoptosis and cell proliferation.

This experimental study was designed to investigate the effects of Sagunja-tang(SGJT), Ijin-tang(IJT), Yukgunja-tang(YGJT) on the change of cerebral hemodynamics [regional cerebral blood f1ow(rCBF), mean arterial blood pressure(MABP), and pial arterial diameter (PAD)] in normal rats, and further to determine the mechanism of action of YGJT. And, this Study was designed to investigate whether YGJT inhibit lactate dehydrogenase(LDH) activity in neuronal cells. The results were as follows ; 1. SGJT significantly increased rCBF but MABP was not changed comparing with normal MABP(l00 %). This results were suggested that SGJT significantly increased rCBF by dilating PAD. 2. IJT significantly decreased rCBF in a dose-dependent, but significantly increased MABP in a dose-dependent. This results were suggested that IJT significantly decreased rCBF by contracting PAD. 3. YGJT significantly increased rCBF and PAD in a dose-dependent, and YGJT increased MABP compared with normal MABP(100 %). This results were suggested that YGJT significantly increased rCBF by dilating PAD. 4. The YGJT-induced increase in rCBF was significantly accelerated by pretreatment with indomethacin (IDN, 1 mg/kg, i.p.), an inhibitor of cyclooxygenase but was significantly inhibited by methylene blue (MTB, 10 ㎍/㎏ i.p.), an inhibitor of guanylate cyclase. 5. The YGJT-induced increase in PAD and MABP were accelerated by pretreatment with IDN but was significantly inhibited by MTB. This results suggested that the mechanism of YGJT is mediated by guanylate cyclase. 6. YGJT inhibited significantly LDH activity in neuronal cells. This results were suggested that YGJT prevented the neuronal death. I thought that YGJT should have improvement of cerebral hemodynamics and inhibitive effect on the brain damage.

Objectives : The purpose of this study was to confirm whether Codonopsis Radix(CR) could be used in the same way for expected indications or diseases of adaptation instead of Ginseng Radix(GR), which acts as a principal herb in Sagunja-tang. Methods : The Traditional Chinese Medicine Systems pharmacology(TCMSP), a database for the study of systems biology related to Chinese medicine, screened potential active compounds in each quartet. By searching for all the proteins that each compound provides, the target of Sagunja-tang with GR(GRST) and the target of Sagunja-tang with CR(CRST) were compared using the network analysis method, and the top ranked target of each serving was selected. Results : Through TCMSP, a Chinese medicine database, the potential effective ingredients of GRST or CRST screened, and the target proteins related to these substances were found to be the most affected by Glycyrrhizae Radix et Rhizome, an herbal medicine mixed in Sagunja-tang, and the target diseases were the same. And the same were found for the target protein, gene and target diseases of GRST and CRST. Conclusions : The prescription with similar composition is likely to have similar network pharmacology analysis results, and the analysis result may be controlled by the herbal medicines which are assumed to be the main function. Therefore, rich and reproducible basic studies is more important because network pharmacological studies can be dominated by data that has been done a lot of previous studies.
