Osteoarthritis is to the abnormality of the inflammatory response of joint tissue caused by various causes such as aging, and muscle loss. In this study, the activity in joint inflammation was verified using SKBE, a plant extract, and the expression levels of arthritis-inducing proteins including MMP-1, MMP-3, MMP-13, and collagen type II in vitro were compared and analyzed. Furthermore, we synthesized α-spinasterol, an active ingredient of SKBE, by the previously reported synthesis method and these findings could provide a new starting point for the development of treatments for osteoarthritis.

Objectives : To study the characteristics and meaning of the division pharmaceutical method in the Donguibogam through analysis of formulas that apply such method. Methods : Each formula applying the division method within the Donguibogam was analyzed Results & Conclusions : In the Donguibogam, medicinals to which the division pharmaceutical method was applied were baizhu[白朮], cangzhu[蒼朮], zhiqiao[枳殼], wuzhuyu[吳茱萸], xiangfuzi[香附子], chuanlianzi[川練子], huangbo[黃柏], etc. Formulas where this method was used were few, while the four methods that were used, together with the Center represents the principle of the five phases. The formulas that applied the division method usually did not adopt the tablet or decoction form, which means they were meant to treat slowly, treating deficiency or stagnation diseases due to problems in the middle-lower body such as the Spleen, Liver and Kidney. It could be said that compared to other more common formulas, this was a unique method. The division pharmaceutical method allows for usage of a wider variety of processing methods compared to single ingredient formulas, while there is lower chance of interference among the different types of processing. Another benefit is that the properties of the main medicinal ingredient could be preserved as much as possible. In addition, the division method allows for the main ingredient and the processed ingredient to interact exclusively, after which the processed medicinal is eliminated leaving only the main ingredient. This allows for maximum improvement of the main ingredient. The division method includes the principles of formula composition as well, whose concept could be positioned between single ingredient formulas and common formulas.

This study was carried out to evaluate the putative anxiolytic-1ike effects of the aqueous extracts of Sanjoin-tang (SJIT) and its ingredients using the elevated plus maze (EPM) test in mice. SJIT consists of five herbs, namely, Zizyphi Spinosi Semen (roasted), Glycyrrhizae Radix, Cnidii Rhizoma, Anemarrhenae Rhizoma, and Hoelen. The aqueous extracts of SJIT and each herbal drug were orally administered to ICR mice, 1 hr before evaluating behavioral activity in the EPM test, respectively. Repeated treatments (for 3 days) of the aqueous extract of SJIT (400 mg/kg) significantly increased time-spend in the open arms and arms entries into the open arms in the EPM test. Zizyphi Spinosi Semen (400 mg/kg), an ingredient of SJIT, significantly increased timespent in the open arms and arm entries into the open arms (P < 0.05). However, the other ingredient of SJIT did not show any anxiolytic-like behaviors. In addition, the anxiolytic-like effects of Zizyphi Spinosi Semen were blocked by pindolol (lO mg/kg), a $5-HT_{1A}$ receptor antagonist. These results suggest that Zizyphi Spinosi Semen (roasted) as an ingredient of SJIT plays a crucial anxiolytic role, and it acts via the serotonergic nervous system.

BIOVITA 3 bacterial species (BIOVITA 3), a probiotic blend powder containing Clostridium butyricum IDCC 1301, Weizmannia coagulans IDCC 1201, and Bacillus subtilis IDCC 1101, has been used as a food ingredient for gut health. However, its efficacy in improving constipation has not been reported. Therefore, we aimed to investigate the functional effects of oral administration of BIOVITA 3 as well as its component strains alone (at 1.0×10⁹ CFU/day) in Sprague-Dawley (SD) rats with loperamide-induced constipation. The study included fecal analysis, gastrointestinal transit ratio, histopathological analysis, short chain fatty acids (SCFAs), and metagenome analysis. As results, the BIOVITA 3 group showed significant improvements in fecal number, water content, gastrointestinal transit ratio, and thickening of the mucosal layer. In the SCFAs analysis, all probiotic-treated groups showed an increase in total SCFAs compared to the loperamide-constipated group. Changes in microbial abundance and the diversity index of three groups (normal, constipated, and BIOVITA 3) were also defined. Of these, the BIOVITA 3 showed a significant improvement in loperamide-constipated SD-rats. This study suggests the possibility that BIOVITA 3 can be applied as an ingredient in functional foods to relieve constipation.

Background: Alzheimer's disease (AD) has memory impairment associated with aggregation of amyloid plaques and neurofibrillary tangles in the brain. Although anti-amyloid β (Aβ) protein antibody and chemical drugs can be prescribed in the clinic, they show adverse effects or low effectiveness. Therefore, the development of a new drug is necessarily needed. We focused on the cognitive function of Panax ginseng and tried to find active ingredient(s). We isolated panaxcerol D, a kind of glycosyl glyceride, from the non-saponin fraction of P. ginseng extract. Methods: We explored effects of acute or sub-chronic administration of panaxcerol D on cognitive function in scopolamine- or Aβ_25-35 peptide-treated mice measured by several behavioral tests. After behavioral tests, we tried to unveil the underlying mechanism of panaxcerol D on its cognitive function by Western blotting. Results: We found that pananxcerol D reversed short-term, long-term and object recognition memory impairments. The decreased extracellular signal-regulated kinases (ERK) or Ca²⁺/calmodulin-dependent protein kinase II (CaMKII) in scopolamine-treated mice was normalized by acute administration of panaxcerol D. Glial fibrillary acidic protein (GFAP), caspase 3, NF-kB p65, synaptophysin and brainderived neurotrophic factor (BDNF) expression levels in Aβ_25-35 peptide-treated mice were modulated by sub-chronic administration of panaxcerol D. Conclusion: Pananxcerol D could improve memory impairments caused by cholinergic blockade or Aβ accumulation through increased phosphorylation level of ERK or its anti-inflammatory effect. Thus, panaxcerol D as one of non-saponin compounds could be used as an active ingredient of P. ginseng for improving cognitive function.

Nonclassical pathway of crystallization has been utilized to modify the properties and morphologies of inorganic and organic/inorganic materials. In here, the polymer-directed crystallization method has been applied to the pharmaceutical active ingredient to assess the applicability for as a particle engineering tool. The polymer-directed crystallization was successful to modifying the crystal size, habit and morphology, but it was not effective to discover the novel polymorphs of Sibutramine (SB). SB was selected as a model drug and polyacrylic acid (PAA), polyethylene imine (PEI) and chitosan (CHI) were added as a crystallization pathway modifier. SB was crystallized via drowning crystallization using methanol or ethanol as a solvent and water as a non-solvent. The significant interactions between polymer and the drug were confirmed by measuring the solubility of the drug in presence of polymer during the crystallization. The crystal forms of SB are characterized by X-ray diffraction (XRD), scanning electron microscope (SEM) and optical microscope (OM). The polymer-directed crystallization seems to be able to modify the crystal properties of pharmaceutical active ingredient, which is critical in determining the bioavailability, processability, and stability.

Eupatilin (5,7-dihydroxy-3",4",6-trimethoxyflavone) is an active ingredient of an ethanol extract of Artemisia asiatica (DA-9601) that is used in the treatment of gastritis. In vitro and in vivo metabolism of eupatilin in the rats has been studied by LC- electrospray mass spectrometry. Rat liver microsomal incubation of eupatilin in the presence of NADPH and UDPGA resulted in the formation of four metabolites (M1-M4). M1, M2, M3 and M4 were tentatively identified as 3"- or- 4"-O-demethyl-eupatilin glucuronide, eupatilin glucuronide, 6-O-demethyleupatilin and 3"-or 4"-O-demethyl- eupatilin glucuronide, eupatilin glucuronide, 6-O-demethyleupatilin and 3"-or 4"-O- demethyl-eupatilin glucuronide, eupatilin glucuronide, 6-O demethyleupatilin and 3"-or 4"-O-demethyl-eupatilin glucuronide, respectively.
