Because of the differences in pharmacological properties between enantiomers of chiral acidic non-steroidal antiinflammatory drugs (NSAIDs) in human body. accurate determinations of their optical purities have been in great need. An efficient capillary electrophoretic (CE) profiling method was developed for the enantioseparation of NSAIDs. Capillary electrophoretic conditions were optimized using TM$\beta$-cyclodextrin as the chiral selectors under MES buffer. (omitted)

Ocotillol-type saponins are one kind of tetracyclic triterpenoids, sharing a tetrahydrofuran ring. Natural ocotillol-type saponins have been discovered in Panax quinquefolius L., Panax japonicus, Hana mina, and Vietnamese ginseng. In recent years, the semisynthesis of 20(S/R)-ocotillol-type saponins has been reported. The biological activities of ocotillol-type saponins include neuroprotective effect, antimyocardial ischemia, antiinflammatory, antibacterial, and antitumor activities. Owing to their chemical structure, pharmacological actions, and the stereoselective activity on antimyocardial ischemia, ocotillol-type saponins are subjected to extensive consideration. In this review, we sum up the discovery, semisynthesis, biological activities, and metabolism of ocotillol-type saponins.

To investigate drug interaction, 23,536 prescriptions published for 1 year were investigated with 'Drug Inter­action Fact 2002'. Dispensing records and a database file written in a local general hospital in South Korea were used as a sample. The number of total cases of drug interaction was 3,238 ($13.76\%$) out of 23,536 prescriptions. The incidence of drug interaction in each prescription the children, the adults, and the elderly were $1.33\%,\;10.97\%,\;25.50\%$, respectively. The incidences of drug interaction per each prescription were $22.03\%,\;20.52\%,\;0.51\%,\;and\;0.36\%$ in neurosurgery, internal med­icine, pediatrics, and orthopedics, respectively. In neurosurgery and internal medicine, risk-high drugs of drug interaction such as antihypertensive drugs, diuretics, and cimetidine were used very often in elderly. In this paper, several suggestions to reduce drug interaction were postulated with regard to the usage of analgesics, non-steroidal antiinflammatory drugs, and antibiotics.

Tissue distributions and association of cyclooxygenase-2 (COX-2) with inflammatory have led us to search for COX-2 selective inhibitors from natural products. Conceptually, COX- 2 selective inhibitors should be expected to retain anti-inflammatory efficacy by inhibition of PGs production while reducing or eliminating the gastric, renal and hemostatic side effects commonly associated with NSAIDs use. Thus, a logical approach to the treatment of inflammatory diseases should involve the inhibitors of COX-2. To develop new COX-2 inhibitors from natural products, two hundred crude drugs were screened by inhibiting PGD2 generation in bone marrow derived mast cells (BMMC). Among them, 6 methanol extracts of crude drugs such as, Bletillae rhizoma, Aconiti kgreani rhizoma, Belamcandae rhizoma, Nelumbinis semen, Gleniae radix, Aurantii immatri pericarpium inhibited more than 85% of BMMC COX-2 activity at a concentration 2.5${\mu}$g/ml.

Neuroinflammation is one of important allostatic loads contributory to the various psychiatric illness. It is mediated mainly by glial cells, which produce both proinflammatory and antiinflammatory cytokines, and the balance of them determines the inflammatory process in the central nervous system. S100 calcium-binding protein B, which is used as an inflammatory marker is also released by glial cells. In the molecular level, oxidative stress contributes to the neuroinflammation. Their disturbances have been revealed in the psychiatric illness and related with the dysregulation of the glutamatergic and monoaminergic systems. There is a possibility to use them as disease markers. The approach for inflammation using antiinflammatory drugs and antioxidants could be connected to the development of disease-modifying treatments. Also, a searching examination about specific subtypes who are vulnerable to inflammation in the patients is required to confirm their efficacy clearly.

Experimental studies were conducted to investigate for the effect of Mahaengkamsuk-tang on analgesic, antipyretic, antiinflammatory, secretion of respiratory tract, isolated ileum. Mahaengkamsuk-tang was composed of Ephedrae Herba, Armenicae Semen, Glycyrrhizae Radix, Gypsum Fibrosum. The following results has been obtained; analgesic and antipyretic actions were obtained. Anti-inflammatory effects in the paw edema induced by 1% dextran was significantly shown in rats. Spontaneous motilities of isolated ileum of mice were strongly suppressed, and contractions of isolated ileum of mice induced by acetylcholine chloride, barium chloride and histamine were remarkably inhibited. Expectorant effect was shown in rabbits. Continuous hypotensive action was seen.

To develop a clinically available saponin- or sapogenin complex from Oriental medicines, the EtOH extract (KPRG-A) was obtained by extracting from the four crude drugs, Kalopanacis Cortex, Platycodi Radix, Rubi Fructus and Glycyrrhizae Radis. The BuOH fraction (KPRG-B), a crude saponin complex, was prepared by fractionating KPRG-A, which were further completely hydrolyzed to afford the sapogenin complex (KPRG-D). In an attempt to find the antinoicpetive effects of the saponin complex and sapogenin complex, KPRG-C, and -D, were assayed by writhing-, hot plate-, and tail-flick tests using mice or rats. The three samples were also subjected to antiiflammatory tests using serotonin-induced and carrageenan-induced hind paw edema mice and rats, respectively. The three samples significantly reduced inflammations and pains of the experimental animal. The potency were found in the order of KPRG-D> KPRG-C> KPRG-B. The most active sample, KPRG-D, caused no death, no body increase or no anatomical pathlogic change even at 2,000 mg/kg dose. These results suggest that a sapogenin complex, KPRG-D, which was found to contain mainly hederagenin, platycodigenin, polygalacic acid, 23-hydroxytormentic acid, glycyrrhetic acid together with minor triterpene acids, could be a potential candidate for antiinflammatory therapeutics.

Ketoprofen, 2-(3-benzoyl phenyl) propionic acid, has many advantages over the other antiinflammatory drugs, such as salicylates, phenytbutazone, and indomethacin. According to the reports, ketoprofen is well tolerated by patients and has very low incidence of side effects and toxic reactions. Although ketoprofen is widely used as an antiinflammatory agent, it shows poor solubility in water. In order to enhance water solubility, ketoprofen was made as lysine salt, such as acetylsalicylate lysine salt, ibuprofen lysine salt and amino acid salt of phenylbuatzone. The purpose of this study was to compare with ketoprofen lysinate in aspect of binding to human serum albumin (HSA) were made, and the association constant and the number of binding site were obtained using difference spectrophotometry. The number of binding site of HSA for ketoprofen and ketoprofen lysinate appears to be 3.3,3.2 respectively and association constants were found as follow; HSA-ketoprofen $2.23{\times}10^4\;M^{-1}$, HSA-ketoprofen lysinate $1.02{\times}10^4\;M^{-1}$.

Gel and cream containing 5% and 10% ketonic fraction (KF) of Leptospermum scoparium, respectively were formulated. Antimicrobial activity, stability, anti-inflammatory effect, rheological properties, drug release and acute toxicity for these topical efficacy were evaluated. Gel and cream containing neomycin or gentamycin in combination with KF has potent antimicrobial activity. Gel and cream were physically stable and did not show any creaming for 6 months storage. Gel showed plastic flow with yield value and cream showed pseudoplastic flow with hysteresis loop. The gel and cream containing KF showed higher viscosity than control or commercial one. The viscosity increased as the concentration of KF increased. Both 10% gel and cream showed a significant decrease in swelling when applied to the carrageenan- injected paw, suggesting local antiinflammatory activity. Particularly, 10% gel preparation showed similar antiinflammatory activity when compared with commercially available drugs. Percent of drug released and diffusion coefficient were in the order of 5% gel, 10% gel, 5% cream, and 10% cream, respectively. There were no significant changes of body weight in rats percutaneously administered with 10% cream and gel when compared with control. There were no induced acute toxicity when 10% cream or gel was applied to rats. Leptospermum scoparium could be practicaly used in topical preparations.
