Background: Third molar extraction is associated with considerable pain and discomfort, which is mostly managed with oral analgesic medication. We assessed the analgesic effect of benzydamine hydrochloride, a topical analgesic oral rinse, for controlling postoperative pain following third molar extraction. Methods: A randomized controlled trial was conducted in 40 patients divided into two groups, for extraction of fully erupted third molar. Groups A received benzydamine hydrochloride mouthwash and group B received normal saline gargle with oral ibuprofen and paracetamol. Oral ibuprofen and paracetamol was the rescue analgesic drug in group A. Patients were evaluated on the $3^{rd}$ and $7^{th}$ post-operative days (POD) for pain using the visual analogue score (VAS), trismus, total number of analgesics consumed, and satisfaction level of patients. Results: The VAS in groups A and B on POD3 and POD7 was $4.55{\pm}2.54$ and $3.95{\pm}1.8$, and $1.2{\pm}1.64$ and $0.95{\pm}1.14$, respectively and was statistically insignificant. The number of analgesics consumed in groups A and B on POD3 ($5.25{\pm}2.22$ and $6.05{\pm}2.43$) was not statistically different from that consumed on POD7 ($9.15{\pm}5.93$ and $10.65{\pm}6.46$). The p values for trismus on POD3 and POD7 were 0.609 and 0.490, respectively and those for patient satisfaction level on POD3 and POD7 were 0.283 and 0.217, respectively. Conclusions: Benzydamine hydrochloride oral rinses do not significantly reduce intake of oral analgesics and are inadequate for pain relief following mandibular third molar extraction.

Background: Turmeric (Curcuma longa L.) that is used as a food material has antioxidant, anticancer and anti-inflammatory properties. Recently the demand for functional foods and drugs has increased. The present study was carried out to determined of contents of residual sulfur dioxide, heavy metals, ash, acid insoluble ash and curcuminoids in turmeric from the Seoul Yak-ryeong market. Methods and Results: A total of 31 samples were obtained. Residual sulfur dioxide was not detected in any samples. Heavy metals (arsenic, cadmium, lead and mercury) were analyzed by ICP-MS (Inductively Coupled Plasma Mass Spectrometer) and a mercury analyzer and were detected in the ranges of 0.00 - 0.28, 0.00 - 0.07, 0.00 - 0.29 and 0.002 - 0.027mg/g respectively. No significant difference were observed between the average heavy metal contents of domestic and imported tumeric. However, average content of ash in domestic samples (7.8%) were significantly higher than that in imported samples (6.1%), whereas that of curcuminoids was significantly higher in imported samples (47.6mg/g) than in domestic samples (11.2mg/g). The average content of acid insoluble ash was not significantly different between two sample types (0.9% in each). Conclusions: There are no specific standards for turmeric used as food materials. Therefore, this study can be provided as basic data for the establishment of quality standards for turmeric.

Background: Studies on the pain have been dealing with many different ways for last several centuries. Especially, preemptive analgesia is being used as a method to control the postoperative pain. Many studies on its efficacy have been processed in different ways about various drugs, administration methods and times for various operations. And the value of preemptive analgesia are still controversial regarding the results of other clinical studies. The authors performed a clinical study on efficacy of preemptive analgesia using an non-steroidal anti-inflammatory drug (NSAID) for the surgical extraction of impacted third molar teeth and present the more effective pain treatment after oral surgery with literature review. Methods: Using a randomized double blind test design, this study compared the analgesic efficacies of an NSAID, Talniflumate 370 mg. This drug administrated first either 1 hour preoperatively (experimental group) or when the pain developed moderately to severely over 5 scale of verbal rating scales (0-10) to respective 30 patients undergoing the removal of impacted third molars. Pain intensity and the time from the end of surgery were assessed postoperatively whenever the patients demanded additional drug over 5 scale for forty eight hours using same verbal rating scales. Results: The sex distribution, the age of the patients. and the time required for surgery in two groups were similar. The average first time for demanding additional drug after surgery was 163.9 minutes in experimental group and 191.5 minutes in control group. At this time, the average pain intensity was 5.8 in experimental group and 6.1 in control group. And the average second time for demanding additional drug was 365.5 minutes in experimental group and 351.8 minutes in control group. At this time. the average pain intensities were 6.6 in experimental group and 6.2 in control group. No statistically significant difference was found between the average first times and second times, and the average pain intensities at first and second times in two groups. Conclusions: From these results the efficacy of preemptive analgesia used in this study was not appeared. This clinical study indicates that many NSAIDs administrated preoperatively in present practices have weak efficacy of preemptive analgesia for postoperative pain, thus the authors recommend that only postoperative analgesics are adequate without preoperative use of analgesics.

An 11-year-old, intact male Pekingese was brought to the Veterinary Teaching Hospital of Kangwon National University with a 10-day history of seizures. Fifteen days before coming to Kangwon National University, the dog had visited a local animal hospital for lameness, and non-steroidal anti-inflammatory drugs were prescribed to treat this symptom. However, 10 days before coming to our hospital, the dog experienced generalized seizures. Two days before his arrival, generalized ataxia and mental dullness also occurred. Our examinations revealed no remarkable findings on a routine blood test or X-ray. However, the neurological examinations confirmed mental dullness, generalized ataxia, and a lack of menace response and pupillary light reflexes. Nine hours later, dyspnea occurred, and 12 hours after that, the patient was euthanized per the client's request. A necropsy of transverse sections confirmed the presence of a prominent midline shift due to extended tumor growth. On histopathological analyses, pseudopalisading necrosis of the glial cells and microvascular proliferation were observed. In immunohistochemical analysis, glial fibrillary acidic protein, proliferating cell nuclear antigens, and ionized calcium binding adaptor molecule 1 immunoreactive cells were observed in the tumor area. Based on the results, the tumor was confirmed to be a glioblastoma. Primary intracranial tumors are rare in the veterinary field. This case report describes the clinical and histopathological findings of glioblastoma in a Pekingese.

Background: Cholestatic hepatitis is failure of bile to reach the duodenum with hepatocellular damage and no demonstable obstruction of the major bile ducts. The prognosis is usually good with recovery in less than 4 weeks after withdrawal of the offending drug. However, a prolonged course lasting over 3 months is possible and, in rare cases, progression to ductopenia with development of a vanishing bile duct syndrome occurs. A differential diagnosis with other causes of Chronic liver disease is needed. Materials and Methods: From January 1991 through January 2000, 14 patients diagnosed as cholestatic hepatitis by liver biopsy were included. The possible causative drug, clinical features, laboratory findings, and progression of cholestatic hepatitis were evaluated. The semiquantitative study of liver lesions was performed by two independent observers. Results: Causes of cholestatic hepatitis are 5 cases of oriental medicine, 3 cases of anti-tuberculosis medication, 1 case of ticlopidine and antibiotics and 4 cases of unknown causes. The clinical features of cholestatic hepatitis were jaundice, itching, urine color change, and general weakness. During 6 to 30 months, LFT of 5 patients showed prolonged elevation. Elevated total cholesterol ${\geq}$250 mg/dL in 6 patients, pheripheral blood eosinophilia in 5 patients, auto-antibody positive in 6 patients were observed respectively. The biopsies showed intralobular bilirubinostasis with a mixed portal inflammatory infiltration. Conclusion: In cholestatic hepatitis, durations of abnormal LFT are variable regardless of causative drugs. If cholestatic hepatitis progresses toward chronic course, viral hepatitis, primary biliary cirrhosis, and autoimmune hepatitis should be differentially diagnosed and sequential liver biopsies are needed.

Zaltoprofen is a propionic acid derivative of non-steroidal anti-inflammatory drugs (NSAIDs) and has been widely used in the treatment of a number of arthritic conditions or lumbago. Zaltoprofen has low water solubility and low bioavailability, therefore great efforts have been devoted to enhance the extent of drug adsorption. In this study, zaltoprofen was formulated into a tablet to enhance the bioavailability and to achieve sustained-release using additives such as lactose monohydrate, carboxymethylcellulose (CMC), hydroxypropylmethylcellulose (HPMC). Fourier transform-infrared (FTIR) and differential scanning calorimeter (DSC) were employed to study the structure and crystallization of zaltoprofen in the tablet with various contents of additives. It was found that additives had interactions with zaltoprofen and inhibited the crystallization of zaltoprofen. Tablets containing low viscosity HPMC showed a higher release than those containing high viscosity HPMC. Also, as the amount of CMC increased zaltoprofen release increased.

Background: Postoperative nausea and vomiting (PONV) frequently occurs following bimaxillary orthognathic surgeries. Compared to opioids, Nefopam is associated with lower incidences of PONV, and does not induce gastrointestinal tract injury, coagulopathy, nephrotoxicity, or fracture healing dysfunction, which are common side effects of Nonsteroidal anti-inflammatory drugs. We compared nefopam- and fentanyl-induced incidence of PONV in patients with access to patient-controlled analgesia (PCA) following bimaxillary orthognathic surgeries. Methods: Patients undergoing bimaxillary orthognathic surgeries were randomly divided into nefopam and fentanyl groups. Nefopam 120 mg or fentanyl $700{\mu}g$ was mixed with normal saline to a final volume of 120 mL. Patients were given access to nefopam or fentanyl via PCA. Postoperative pain intensity and PONV were measured at 30 minutes and 1 hour after surgery in the recovery room and at 8, 24, 48, and 72 hours after surgery in the ward. The frequency of bolus delivery was compared at each time point. Results: Eighty-nine patients were enrolled in this study, with 48 in the nefopam (N) group and 41 in the fentanyl (F) group. PONV occurred in 13 patients (27.7%) in the N group and 7 patients (17.1%) in the F group at 8 hours post-surgery (P = 0.568), and there were no significant differences between the two groups at any of the time points. VAS scores were $4.4{\pm}2.0$ and $3.7{\pm}1.9$ in the N and F groups, respectively, at 8 hours after surgery (P = 0.122), and cumulative bolus delivery was $10.7{\pm}13.7$ and $8.6{\pm}8.5$, respectively (P = 0.408). There were no significant differences in pain or bolus delivery at any of the remaining time points. Conclusion: Patients who underwent bimaxillary orthognathic surgery and were given nefopam via PCA did not experience a lower rate of PONV compared to those that received fentanyl via PCA. Furthermore, nefopam and fentanyl did not provide significantly different postoperative pain control.

Wound care is a health industry concern affecting millions worldwide. Recent increase in metabolic disorders such as diabetes comes with elevated risk of wound-based complications. Treatment and management of wounds are difficult practices due to complexity of the wound healing process. Conventional wound dressings and treatment applications only provide limited benefits which are mainly aimed to keep wound protected from external factors. To improve wound care, recent developments make biopolymers to be of high interest and importance to researchers and medical practitioners. Biopolymers are polymers or natural origin produced by living organisms. They are credited to be highly biocompatible and biodegradable. Currently, studies reported biopolymers to exhibit various health beneficial properties such as antimicrobial, anti-inflammatory, hemostatic, cell proliferative and angiogenic activities which are crucial for effective wound management. Several biopolymers, namely chitosan, cellulose, collagen, hyaluronic acid and alginic acid have been already investigated and applied as wound dressing agents. Different derivatives of biopolymers have also been developed by cross-linking with other molecules, grafting with other polymers, and loading with bioactive agents or drugs which showed promising results towards wound healing without any undesired outcome such as scarring and physiological abnormalities. In this review, current applications of common biopolymers in wound treatment industry are highlighted to be a guide for further applications and studies.

Objective: This study was conducted to evaluate whether the co-injection of antioxidants together with foot-and-mouth disease (FMD) vaccination has the potential to attenuate the negative effects caused by vaccination in Holstein finishing steers. Methods: A total of 36 finishing Holstein steers (body weight [BW]: $608{\pm}45.6kg$, 17 months old) were randomly allocated to one of three treatments: i) control (CON, only FMD vaccination without any co-injection), ii) co-injection of commercial non-steroidal anti-inflammatory drugs (NSAID) with FMD vaccination at a ratio of 10:1 (NSAID vol/FMD vaccine vol) as a positive control (PCON), iii) co-injection of commercial mixture of vitamin E and selenium with FMD vaccination (VITESEL) (1 mL of FMD vaccine+1 mL of antioxidants per 90 kg of BW). Changes in growth performance and blood parameters because of treatments were determined. Results: No significant difference in BW, average daily gain, and dry matter intake of the steers was observed among the treatments. The FMD vaccination significantly increased white blood cells (WBC), neutrophils, platelets, and mean platelet volume (p<0.01) in blood analysis. The count of lymphocyte tended to increase after vaccination (p = 0.08). In blood analysis, steers in VITESEL tended to have higher numbers of WBC, neutrophils, and platelets compared to that of other treatments (p = 0.09, 0.06, and 0.09, respectively). Eosinophils in VITESEL were higher than those in PCON (p<0.01). Among blood metabolites, blood urea nitrogen and aspartate transaminase were significantly increased, but cholesterol, alanine transferase, inorganic phosphorus, Mg, and albumin were decreased after FMD vaccination (p<0.01). Conclusion: The use of antioxidants in FMD vaccination did not attenuate growth disturbance because of FMD vaccination. The metabolic changes induced by vaccination were not controlled by the administration of antioxidants. The protective function of antioxidants was effective mainly on the cell counts of leukocytes.

Cyclophosphamide (CP) is widely used in cancer and lymphoma treatments and as an immunosuppressant drug. CP is a DNA alkylating agent that metabolizes into 4-hydrocyclophosphamide (4H-CYP) and aldophosphamide in hepatocytes. However, its metabolites cause DNA synthesis disorder, leading to apoptosis and toxic side effects. The development of technology to minimize this side effect is essential to improve CP's clinical application. Various bioactive compounds have been reported to have anti-cancer and antioxidant functions and preventive or therapeutic roles in metabolic diseases. Many researchers have attempted to minimize the side effects and improve the efficacy of these drugs together with the use of bioactive compounds. Ulmus macrocarpa Hance has been used for the treatment of edema, mastitis, stomach pain, tumors, cystitis, and other inflammatory diseases. The aim of this study was to investigate at the histological level the protective function of U. macrocarpa Hance against CP's side effects and any potential toxic effect of U. macrocarpa Hance in the liver and kidney. Water extracts of U. macrocarpa Hance reduced CP-induced toxicity and did not induce any histological damage in the liver and kidney. Therefore, U. macrocarpa Hance would be applicable in the pharmaceutical industry.
