Objectives Eucommiae cortex is one of the frequently used herbs for musculoskeletal disorders, with well-known anti-inflammatory effect. Meanwhile, powdered form of herbal drugs is more advantageous than decoction form, in that storing and taking is more convenient. Thus, the authors aimed to investigate whether the drying method affects the index compound level and anti-inflammatory effect of eucommiae cortex water extract. Methods Eucommiae cortex was extracted in distilled water at $100^{\circ}C$ for 3 hours, filtered, and then evaporated under vacuum. One half of the sample was freeze-dried at $-80^{\circ}C$. Another half of the sample was added with dextrin and then spray-dried at $180^{\circ}C$. To assess the possible change in index compound content, pinoresinol diglucoside was selected as the index marker. The content level of the index compound in various extract sample was quantified through high performance liquid chromatography. In addition, iNOS assay in LPS-induced RAW 264.7 cells was adopted to determine the anti-inflammatory effect of various extract samples. Furthermore, MTT assay was performed to confirm that the result of iNOS assay was not due to cytotoxicity. Results There was no significance difference in index compound content between extract samples obtained through two different drying methods. Anti-inflammatory activity of extract samples were similar at the matching concentration, regardless of the drying methods. Extract samples did not show any significant cytotoxicity. Conclusions Extract samples of eucommiae cortex were obtained through freeze-drying and spray-drying. Neither change in index compound content nor difference in anti-inflammatory activity was observed between drying methods.

Background & Objective : The herbal medicine Sojukgunbihwan granule has been used for the treatment of functional dyspepsia, generally categorized as a gastric dysmotility disease. However, its mechanisms are not yet well known. Therefore, the effects of Sojukgunbihwan granules on gastric motility in rats was investigated. Methods : The myoelectrical activity of the gastric smooth muscle was recorded by a bipolar electrode placed at the gastric antrum of rats. The contractile waves were measured for 30 minutes before and after intragastric administration of each solution(normal saline, Pyungwisan 40mg/kg, Sojukgunbihwan granules 60mg/kg) and expressed as the motility index. Gastric emptying was measured by the number of glass beads expelled from the stomach(containing one hundred 1mm glass beads) within an hour after glass beads and test drugs(normal saline, Pyungwisan 40mg/kg, Pyungwisan 120mg/kg, Sojukgunbihwan granules 60mg/kg, Sojukgunbihwan granules 180mg/kg) were administered. In another series of experiments to evaluate the mechanisms of Sojukgunbihwan granules under delayed conditions, the rats were treated with atropine sulfate(1 mg/kg, s.c.), cisplatin(10mg/kg, i.p.), and NAME($N^G$-nitro-L-arginine methyl ester, 75mg/kg, s.c.) respectively. Results : Intragastric administration of Sojukgunbihwan granules increased the myoelectrical activity significantly, gastric motility index rose 25%, and gastric emptying of glass beads was significantly enhanced over a period of 60minutes. Under the delayed gastric emptying induced by atropine sulfate, cisplatin, and NAME, Sojukgunbihwan granules aggravated gastric emptying in the atropine sulfate($5.71{\pm}3.45\;vs\;3.71{\pm}4.42$) and cisplatin($13.86{\pm}3.53\;vs\;5.14{\pm}5.05$, p<0.01) treated groups, but enhanced gastric emptying in the NAME treated group($5.00{\pm}3.21\;vs\;11.71{\pm}5.65$, p<0.05). Conclusions : Results suggest that Sojukgunbihwan granules stimulate gastric motility through cholinergic and 5-hydroxytryptamine 3 receptors. Results are indicative of Sojukgunbihwan as an especially effective remedy in dysmotility-like functional dyspepsia with impaired reservoir functions such as gastric adaptive relaxation.

Objectives: This study aimed to report a case that showed improvements in the symptoms of patients with alcoholic hepatitis without any indication of deterioration of the disease. Methods: Western medicine with Urusa tablets and Godex capsules and Korean medicine therapeutic approaches, including Shihogayonggolmoryo-tang, acupuncture, and moxibustion, were administered to a patient during the period of treatment. Blood tests were used to determine levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), AST/ALT ratio, alkaline phosphatase (ALP), gamma glutamyltransferase (GGT), total bilirubin, direct bilirubin, and total cholesterol. Fatigue was measured using the numeric rating scale (NRS), and the patient's total sleeping time was checked, daily. Results: After the combined treatment, the AST/ALT ratio and the AST, ALT, ALP, GGT, total cholesterol, and direct bilirubin levels were decreased. Through Oriental medicine for the purpose of improving symptoms, NRS of fatigue decreased from 10 to 5, and the amount of sleeping time increased from 2 to 5 hours. Conclusions: The herbal medicine had no effect on the hepatoprotective drugs such as Urusa tablets and Godex capsules used to treat alcoholic hepatitis, and no adverse reaction from the combined administration was observed. To reduce fatigue and insomnia in patients with alcoholic hepatitis, it might be helpful to combine Western medications with Korean medicine treatments, including acupuncture, moxibustion, and Shihogayonggolmoryo-tang.

This study is about photosensitive microspheres prepared by coating alginate microspheres with gelatin-cinnamic acid conjugate. Firstly, alginate microspheres was prepared in water-in-oil (W/O) emulsion and then they were coated with gelatin- cinnamic acid conjugate. Herein, gelatin-cinnamic acid conjugate is obtained by the amidation between an amine group of gelatin and a carboxy group of cinnamic acid. Cinnamic acid is widely used as a photo-responsive material easy to dimerize and dedimeriz under UV irradiation at ${\lambda}$ = 254 nm and ${\lambda}$ = 365 nm, respectively. As shown in SEM-EDS, alginate was successfully coated with gelatin-ciannmic acid. By determining the absorbance of coated microspheres at 270nm, the amount of cinnamic acid per microspheres was 0.13/1. The SEM photos showed the size of coated microspheres is around $10{\mu}m$. And the degrees of dimerization and dedimerization were calculated to be 49% and 23% respectively. Then the release of FITC-dextran from the coated micrspheres was studied and release the degree was 42%. As a result, the coated microspheres have potential to be used as a photo-responsive drug carrier to delivery drugs.

Objectives: Hwangryunhaedok-tang (HHT; Huanglianjiedu-tang, Orengedoku-to), a traditional herbal formula, is used for treating inflammation, hypertension, gastritis, liver dysfunction, cerebrovascular diseases, dermatitis and dementia. The objective of this study was to assess the sub-acute toxicity of HHT in Sprague-Dawley (SD) rats, and its effect on the activities of human microsomal cytochrome P450s (CYP450s) and UDP-glucuronosyltransferases (UGTs). Methods: Male and female SD rats were orally administered HHT once daily at doses of 0, 500, 1000 and 2000 mg/kg for 4 weeks. We analyzed mortality, clinical observations, body weight, food consumption, organ weights, urinalysis, hematology, serum biochemistry, and histopathology. The activities of major human CYP450s (CYP1A2, CYP3A4, CYP2B6, CYP2C9, CYP2C19, CYP2D6, and CYP2E1) and UGTs (UGT1A1, UGT1A4, and UGT2B7) were assessed using in vitro fluorescence- and luminescence-based enzyme assays, respectively. Results: No toxicologically significant changes related to the repeated administration of HHT were observed in both male and female SD rats. The no observed adverse effect level (NOAEL) value was more than 2000 mg/kg/day for both sexes. HHT inhibited the activities of human microsomal CYP1A2, CYP2C19, CYP2D6, and CYP2E1, whereas it weakly inhibited the activities of CYP2B6, CYP2C9, CYP3A4, and UGT1A1. In addition, HHT negligibly inhibited the activities of human microsomal UGT1A4 and UGT2B7 with $IC_{50}$ values in excess of $1000{\mu}g/mL$. Conclusions: Our findings indicate that HHT may be safe for repeated administration up to 4 weeks. In addition, these findings provide information on the safety and effectiveness of HHT when co-administered with conventional drugs.

Immune-mediated hemolytic anemia(IMHA) is one of the most common causes of anemia in small animals and immune-mediate thrombocytopenia(IMT) is also an immune mediated disease that affects small animals. The initial treatment for IMHA and IMT is medical suppression of the immune system with glucocorticoids and other immunosuppressive drugs. However, even with appropriate treatments, some animals are not responsive to the treatment and may need further immunosuppressive therapies or some alternative medicines. An eight-year-old spayed female Siamese cat with IMHA and an eight-year-old castrated male King Charles Spaniel dog with IMT were referred to the traditional medical service of the veterinary medical center. Both animals were unresponsive to steroids or other immunosuppressive treatments. Gui-Pi-Tang, one of the traditional herbal medicines, was administered to the animals. After 1-month of Gui-Pi-Tang administration, the packed cell volume(PCV) of the cat and platelets count of the dog had showed remarkable improvement. After four months of follow up in the cat, and 18 months of follow up in the dog, the improved PCV and platelet counts of the animals were maintained normally. Therefore, Gui-Pi-Tang might be considered as an alternative treatment in small animals with immune-mediated blood disorders.

We have studied the physico-chemical change and pharmacological transformation of traditional herbal medicines with processing. Evodia fruit (EF) has processed for the purpose of detoxification and reduction of its bitter taste. There are various methods of processing EF in Oriental medicinal reference. Among them, we processed EF according to the method of Sang-han theory, the most famous medicinal reference. We processed EF with washing in hot water, and then dried. Processed EFs(PEFs) were prepared according to the above procedure through repetition of 1,3,5 and 7 times respectively. The contents of weight loss, water extract, diluted ethanol extract, ether extract, total ash, acid insoluble ash, alkaloids and limonin in non-processed EF (NPEF) and PEFs were examined. The weight loss, and contents of water extract and dilute ethanol extract in PEF showed decrease in proportion to increase of washing time, while the contents of ether extract, total ash and acid insoluble ash showed little change as compared with those of NPEF. And the content of evodiamine and rutaecarpine was not changed distinctly. However, the content of limonin decreased in the final processed material in proportion to increase of washing times with hot water. And the intense of bitter taste in PEF was also reduced. These results were ascribed to the flowing-out of the water-soluble portion. The biological activities of NPEF and PEF were also investigated. In the test of DPPH scavenging effect, xanthine oxidase inhibition effect and TBA-Rs effect, PEF was more effective than NPEF in vitro. Also, both NPEF and PEF showed potent analgesic and anti-inflammatory effects against in mice. Especially, PEF by 3 times washing with hot water was more effective than other PEFs. From these results, it is considered that PEF should be prepared by 3 times washing with hot water.

Clinical and preclinical trials of involving drugs with anti-obesity effects have focused on screening for herbal medicines suspected to have anti-obesity activities. In this study, an extract of Aster scaver Thunb., which was prepared in 80% methanol (ASE), was assessed for its total phenol content, total flavonoid content, antioxidant activity ability to scavenge the ${\alpha}-{\alpha}$-diphenyl-${\beta}$-picrylhydrazyl, 2,2'-azino-bis-[3-ethylbenzthiazoline]-6-sulfonic acid radical, and anti-adipogenic effects. The anti-adipogenic effect of ASE on the differentiation of 3T3-L1 pre-adipocytes to adipocytes was investigated by assaying the suppression of adipocyte differentiation and lipid accumulation by using western blot analysis and the Oil Red-O assay, respectively. The staining results showed that ASE significantly inhibited 3T3-L1. Western blot analysis results showed that ASE decreased the levels of peroxisome proliferator-activated receptor-${\gamma}$, CCAAT/enhancer-binding protein ${\alpha}$, and sterol regulatory element-binding protein 1c. These results demonstrate that ASE directly inhibits the differentiation of preadipocytes, and might be an important adjunct in the therapeutic efforts to reduce adipogenesis.
