  • In order to reduce the systemic side effects and gastrointestinal irritation of ketoprofen after its oral administration, it was formulated as a 3% ketoprofen gel (ID-GEL) with Pluronic F-127. The pharmacokinetic characteristics of ID-GEL was evaluated following its transdermal application on the dorsal skin of rats at the dose of 9 mg/kg in reference to those of existing 3% ketoprofen gels. Even though the maximum concentration of 810 ng/ml was reached at 6 hrs postdose, the plasma concentration was kept almost constant until 24 hrs postdose, which suggested that ketoprofen was released continuously from the gel during this period. The bioavailability of ID-GEL was two times higher than those of existing 3% ketoprofen gels, based on the calculated area under the plasma concentration-time curves after the percutaneous administration.

  • In this study general pharmacological profiles of KI-60606 on the central nervous system, the cardiovascular system and the other organs were investigated. The dosages given were 0,5, 10 and 25 mg/kg and drugs were administered intravenously. The animals used for this study were mice, rats, cats and guinea pigs. KI-60606 showed no effects on general behavior, motor coordination, spontaneous locomotor activity, hexobarbital-induced hypnosis time, body temperature, analgesic activity, anticonvulsant activity and contraction of nictitating membrane in cats. Furthermore KI-60606 showed no effects on blood pressure, heart rate, LVP (left ventricular peak systolic pressure), LVEDP (left ventricular end diastolic pressure), LVDP (left ventricular developing pressure), DP(double product), CFR(coronary flow rate), smooth muscle contraction using guinea pig ileum and gastric secretion at all dosage tested except the increase of gastrointestinal transport and urinary $K^+$ excretion.

  • Affecting more than half of menstruating women, dysmenorrhea is a cramp which causes abdominal or lower back pain just before or during a menstruation. In western medicine, non-steroidal anti-inflammatory drugs (NSAIDs) are normally used to treat primary dysmenorrheal symptoms. Despite their rapidity in relieving pain, NSAIDs have many serious side effects on the liver, kidney, and gastrointestinal tract. Thai traditional medicines comprise many preparations for treating dysmenorrhea, especially Prasaplai preparation which has been listed in the Thai traditional common household drug list since 2006. The use of Prasaplai was originated about 100 years ago and is still being used in the present time to treat dysmenorrhea. This review focuses on the history of the preparation, active ingredients, and biological activities especially on cyclooxygenase inhibitor, artifacts occurred in the preparation, quantitative analysis, and clinical trial of Prasaplai formulation.

  • This study was conducted to investigate the effets of chitosan and beef tallow at different level on glucose and lipid metabolism in rats. Dietary fot level was 20% and 40%, and chitosan was given at levels of 0%, 3%, and 5%(wt/wt) of diet. Chitosan supplement tended to decrease the serum total lipids, total cholesterol, and triglycerides. HDL cholesterol and HDL cholesterol : total cholesterol ratio tended to increase with 5% chitosan supplementation. LDL cholesterol and VLDL triglyceride tended to decrease with chitosan supplementation. Lipid concentration of liver and epididymal fat pad(EEP) tended to decrease with medium dietary fat and chitosan treatment. fecal excretion of total lipid and triglyceride exhibited a tendency to increase with high fat levels and chitosan. Length of small intestine and gastrointestinal transit time were not affected by dietary fit levels or chitosan supplements. Therefore, it could be suggested that chitosan supplement had beneficial effects on lipid metabolism. (Korean J Nutrition 31(7) : 1112-1120, 1998)

  • In order to compare the iron concentrations of the marketed ferruginous hematinics with the sustained-releasedosage forms and to prepare the good hemantinic which can be absorbed effectively without forming "iron block" in the gastrointestinal tract, gelatinized micropellets containing medicament were prepared and hardened in 10% formalin-isopropanol in the time of 72 hours. These micropellets were digested with artificial gastric juice and plotted a curve of released iron concentration. As a result, it is found that gelatinized micropellets sustained-release dosage form is an excellent ferruginous hemantinic and it is shown that several marketed preparations can be improved in their hemantinic actions by forming the sustained-release dosage.se dosage.

  • Loxoprofen-Na (sodium 2-〔4-(2-oxocyclopentylmethyl)pheny)propionate dihydrate) is a potent analgesic drug. We developed loxoprofen-Na plasters to extend duration time of analgesic activity and to reduce side effect on gastrointestinal tract. Analgesic effect of Loxoprofen-Na plasters was investigated. Loxoprofen-Na plaster had good analgesic effect in rat paw pressure test, Tail-flick latency test and acetic acid-induced writhing test. Also, it had anti-inflammatory effect on carrageenan-induced rat hind paw edema. In pharmacokinetic study of Loxoprofen-Na, plasters dosage form showed that plasma drug concentration was prolonged up to 14 hours. So, we can conclude that loxoprofen-Na plasters, when applied on skin, will be a new type of drug for controlling the various local pain or inflammation.

  • PEG-hemoglobin SB1 (SB1), which is a hemoglobin-based oxygen carrier, is intended to use as a safe blood substitute against brain ischemia and stroke. The general pharmacological profiles of SB1 were studied. The doses given were 0, 5, 10, 20 ml/kg and drugs were administered intravenously. The animals used for this study were mouse, rat and guinea pig. SB1 showed no effects on general behavior, motor coordination, spontaneous locomotor activity, hexobarbital sleeping time, anticonvulsant activity, analgesic activity, blood pressure and heart rate, left ventricular peak systolic pressure, left ventricular end diastolic pressure, left ventricular developing pressure, double product, heart rate, coronary flow rate, smooth muscle contraction using guinea pig ileum, gastrointestinal transport, gastric secretion, urinary volume and electrolyte excretion at all doses tested except the decrease of body temperature. These findings demonstrated that SB1 possesses no general pharmacological effects at all doses tested.

  • Crohn's disease is a chronic inflammatory disorder of the gastrointestinal tract and characterized by relapsing and remitting episodes, with progression over time to complications of stricture, fistulas, or abscesses. The etiology is unknown, although the common opinion is that the disease arises from a disordered immune response to the gut contents in genetically predisposed individuals. Infliximab is a mouse-human chimeric antibody against tumor necrosis factor ${\alpha}$, and has proven to be effective in active Crohn's disease for both induction and maintenance therapy. Despite the growing experience with infliximab in Crohn's disease, optimal treatment strategies still need to be determined. The purpose of this review is to summarize the current knowledge on the use of infliximab in Crohn's disease and to discuss the yet-unsolved issues.

  • Surgical outcomes of colorectal cancer treatment depend not only on good surgery and tumor biology but also on an optimal perioperative care. The enhanced recovery program (ERP) - a multidisciplinary and multimodal approach, or so called 'fast-track surgery' - has been designed to minimize perioperative and intraoperative stress responses, and to support the recovery of organ function aiming to help patients getting better sooner after surgery. Compared with conventional postoperative care, the enhanced recovery program results in quicker patient recovery, shorter length of hospital stay, faster recovery of gastrointestinal function, and a lower incidence of postoperative complications. Although not firmly established as yet, the enhanced recovery program after surgery could be of oncological benefit in colorectal cancer patients because it can enhance recovery, maintain integrity of the postoperative immune system, increase feasibility of postoperative chemotherapy, and shorten the time interval from surgery to chemotherapy. This commentary summarizes short-term outcomes and potential long-term benefits of enhanced recovery programs in the treatment of colorectal cancer.
