Objectives : I analysed daehwangmokdan-tang's compatibility principle by the system of chief, deputy, assistant, and envoy and investigated pharmacological activities by categorizing with chemical components, molecular level, cellular level, animal level and human level based on Korean and Chinese studies for this formula. Methods : Daehwangmokdan-tang's compatibiltity principle was examined by the system of chief, deputy, assistant, and envoy. I looked into studies that presented in Korea from 1956 to 2016 about daehwangmokdan-tang through KOREA INSTITUTE OF ORIENTAL MEDICINE, Korean medicine information system (OASIS) and in Chinese for 20 years about daehwangmokdan-tang through China National Knowledge Infrastructure, CNKI. Then classify into chemical components, molecular level, cellular level, animal level and human level to analyse. Results : According to the system of chief, deputy, assistant, and envoy, chief herb is Rhei Radix et Rhizoma and Moutan Cortex, deputy herb is Natrii Sulfas and Persicae Semen, assistant and envoy herbs are Trichosanthis Semen. The amount of extraction of paeonol, total anthraquinone, and conjugated anthraquinone from daehwangmokdan-tang with the formulation of the system of chief, deputy, assistant, and envoy was the highest, and in the formulation of chief herb and deputy herb, the extraction amount of paeonol and conjugated anthraquinone was the lowest. With other formulations, the amount of extraction of total anthraquinone and conjugated anthraquinone was improved, although the degree was different. In particular, when it is blended with Persicae Semen as a deputy herb, the extraction amount of total anthraquinone and conjugated anthraquinone of Rhei Radix et Rhizoma as a chief herb is greatly increased, and the extraction amount of paeonol is rather different, but it is lowered. It was found that the amount of Mg Ca K Na in daehwangmokdan-tang was the highest. Pharmacological activities can be detected in inflammatory mediators and enzymes for molecular level. For cellular level, it can be determined in lipopolysaccharide (LPS)-stimulated RAW 264.7 cell line. In mouse and rats for animal level and human level, in inflammatory diseases (acute appendicitis, acute pancreatitis, acute cholecystitis, acute abdominal disease, ect.), pharmacological activities was caught. Conclusions : From the above results, daehwangmokdan-tang is composed in line with the system of chief, deputy, assistant, and envoy, suggesting that there is certain rationality and scientific. Pharmacological activities of daehwangmokdan-tang are effective to anti-inflammation, improvement of sepsis, analgesic, muscle relaxation, and improvement of intestinal flora and its metabolites. Daehwangmokdan-tang is consistent with the action of diuresis and anti-inflammation in terms of the content of elements, suggesting that there is action of purging fire and removing blood stasis, defecation detoxification, cooling blood and clearing heat and activating blood and dispersing stasis.

The experimental study used in this paper was done to examine the clinical effects of Taeumchowetang for the gastric ulcer and the function of gastrointestinal tract using rats and mice which were administered orally the water extraction from Taeumchowetang. Then, the counter-action of the water extraction on the isolated ileum and gastric fundus, the inhibitory effects of pylorus-ligated ulcer and indomethacin-induced ulcer, the associations with gastric juice secretion, total acidity, pepsin output, the transportability in the small and large intestine, were studied with administering acetylcholine chloride and barium chloride. In addition, it was investigated whether the central nervous system related to pain control and sleeping time was influenced by Taeumchowetang. The following results have been obtained; 1. As resulting from injection of acetylcholine chloride and barium chloride into the isolated ileum of rats and mice, Taeumchowetang led to have an inhibitory effect on the muscle contraction of the ileum. Then, acetylcholine chloride was measured as lower effect than barium chloride 2. For the inhibitory effect on contraction for the gastric fundus strip in rats by either acetylcholine chloride or barium chloride, the one showed low inhibitory effect, on the other hand the other showed density-dependent effect. 3. The water extraction was given on the pylorus ligated ulcer with using two different administration groups of 1,300mg/kg and 2,600mg/kg, each result was measured as 22.9% and 36.5% for an ulcerous inhibitory effect (p<0.05). 4. According to the two administration groups, the preventive effect was tabulated 18.1% and 29.3% for indomethacin-induced ulcer (p<0.05, P<0.01). 5. For associations with gastric juice secretion, total acidity, pepsin output in the administration group 2,600mg/kg, Taeumchowetang was recognized as having an inhibitory effects related to suppressive actions involving gastric juice secretion(p<0.05), and free acidity(p<0.01), but there was no significant association with total acidity and pepsin output. 6. To know the transportability in the intestine, BaSO4 solution was used. The transportability of the small intestine in the administration group 2,600mg/kg was 22.2% which was statistically significant compared with the large intestine's transportability(P<0.01). 7. In the administration group 1,300mg/kg and 2,600mg/kg, analgesic effect with against acetic acid was measured as being 16.8% and 24.4% which was shown as statistically siginificant(p<0.01). 8. No statistically significant association between Taeumchowetang and sleeping time was found in both 1,300mg/kg and 2,600mg/kg by administering phenobarbital-Na. According to the results of this study, Taeumchowetang has agreed with the effects of literature review. Further more in this study, Taeumchowetang also has preventive effects on pylorus-ligated ulcer. Hence, Teaumchowetang can be significant effect such as both anti ulcer agent and increasing gastric activity for the patients who suffer from gastric ulcer.

To study effective dossage and administration route for scaling, ketamine HCl/propionyl promazine HCl(ketamine) combination and tiletamine HCl/zolazepam HCl(zoletil) were administered in one hundred six dogs. The dogs were toy poodle, Yorkshire Terrier, Pekingese and Chihuahua. Scaling and polishing time, possible treatment time after the first injection of anesthetics, the number of anethesia added, presence of tongue movement during anesthesia, the presence of swaying sign during recovery and respiration were evaluated. The possible treatment time after the first Injection of anesthetic in toy poodle were 26.3${\pm}$3.0 minutes with intravenous(IM) treatment of ketamine 10mg/kg, and 21.4${\pm}$6.6 minutes with intramuscula(IM) treatment of zoletil 8mg/kg, In Yorkshire Terrier were 19.51: 1.7 minutes with IV treatment of ketamine 10mg/kg. 19.0${\pm}$5.2 minutes IM and 20.8${\pm}$6.1 minutes with IM treatment of zoletil 5mg/kg,24.8${\pm}$3,5 minutes with IM treatment of zoletil 8mg/kg. In pekingese were 27.5${\pm}$2.1 minutes with IM treatment of ketamine 10mg/kg,28.0${\pm}$4.2 minutes with IM treatment of zoletil 8mg/kg. In Chihuahua were 19.5${\pm}$1.9 minutes with IV treatment of ketamine 7mg/kg, 17.5${\pm}$1.7 minutes with IM treatment of ketamine 10mg/kg and 20.3${\pm}$3.8 minutes with IM treatment of zoletil 5mg/kg, 21.2${\pm}$5.5 minutes with IM treatment of zoletil 8mg/kg. Swaying sign was observed in all group during recovery time, espically, in toy poodle and Yorkshire Terrier which administered zoletil 8mg/kg IM showed more severe swaying sign. The present results suggested that injection of zoletil 8mg/kg IM might be relatively effective for scaling in Chihuahua Within 20 minutes treatment for scaling in Yorkshire Terrier and Chihuahua, IM treatment of ketamine 7 to 10mg/kg is recommended.

Objective: As a manual accupucture method, the twirling-needle treatment has been known more effective in relieving pain than the conventional simple accupuncture treatment. Finding a proper treatment condition is difficult because of the lack of a quantative measurement of the alleviation of pain made by acupuncture. In this research, the authors propose the use of infrared thermal images in a formalin test to quantatively verify the effect of twirling. Methods: After injecting 10%~20% formalin into the tail of rats, the infrared thermal images(ITI) have been obtained to estimate the thermal distribution caused by inflammation. The authors propose a processing method to measure the thermal distribution from the thermal images obtained from the infrared camera as a pain model of the formalin test. Results: The pain model obtained from the infrared thermal image has two phases. The first phase, which is a transient period, is the initial 20 minutes when the pain is developed after the formalin injection. The second phase, which is a steady state, is where the development of pain lasts for 60 minutes or more after the first stage. This characteristic of the proposed model based on ITI is consistent with that of the pain model reported by other researchers whose works are based on the time-course of flinching and licking/biting, following a different concentration of formalin. It is noticed that the response of the thermal distribution obtained from ITI shows very high correlation to the behavioral response in the formalin test performed by Kazuhiro Okuda and four others5). In addition, the authors propose an ITI method to determine the pain-reducing effect of the acupuncture. The thermal distribution obtained from the experiment shows that there is significant pain reducing effect made by the twirling-needle method.

Background: Preterm labor and miscarriage may occur in stressful situations, such as a surgical operation or infection during pregnancy. Pharyngeal and buccal abscess and facial bone fractures are inevitable dental surgeries in pregnant patients. Remifentanil is an opioid analgesic that is commonly used for general anesthesia and sedation. Nonetheless, no study has investigated the effects of remifentanil on amniotic epithelial cells. This study evaluated the effects of remifentanil on the factors related to uterine contraction and its mechanism of action on amniotic epithelial cells. Methods: Amniotic epithelial cells were preconditioned at various concentrations of remifentanil for 1 h, followed by 24-h lipopolysaccharide (LPS) exposure. MTT assays were performed to assess the cell viability in each group. The effects of remifentanil on factors related to uterine contractions in amniotic epithelial cells were assessed using a nitric oxide (NO) assay, western blot examinations of the expression of nuclear factor-kappa B (NF-κB), cyclooxygenase 2 (COX2), and prostaglandin E2 (PGE₂), and RT-PCR examinations of the expression of the proinflammatory cytokines interleukin (IL)-1β and tumor necrosis factor-alpha (TNF-α). Results: Remifentanil did not affect viability and nitric oxide production of amniotic epithelial cells. Western blot analysis revealed that remifentanil preconditioning resulted in decreased expressions of NF-κB and PGE2 in the cells in LPS-induced inflammation, and a tendency of decreased COX2 expression. The results were statistically significant only at high concentration. RT-PCR revealed reduced expressions of IL-1β and TNF-α. Conclusions: Preconditioning with remifentanil does not affect the viability of amniotic epithelial cells but reduces the expression of factors related to uterine contractions in situations where cell inflammation is induced by LPS, which is an important inducer of preterm labor. These findings provide evidence that remifentanil may inhibit preterm labor in clinical settings.

Objectives : 'Obtaining qi(deqi)' is a sensation experienced by a patient or an acupuncturist during acupuncture treatment, and it is considered to be an important factor in acupuncture treatment. However, previous studies reported conflicting results about the relationship between 'obtaining qi(deqi)' sensation and the effect of acupuncture treatment. Also, most of the previous studies investigating 'obtaining qi(deqi)' and the acupuncture effect, dealt with the analgesic effect of acupuncture. The objective of this study was to analyze the relation between the 'obtaining qi(deqi)' and the anti-itching effect of acupuncture treatment. Methods : Twenty one healthy subjects participated in this study. At the first visit, itch was induced to all subjects using intradermal injection of histamine on the lower arm. At the second visit, acupuncture treatment was applied using LI11 and 'obtaining qi(deqi)' was assessed. After acupuncture treatment, itch was induced again, and itch VAS and skin flare were assessed. Results: At the 6,8,10 minutes after histamine injection, the change of itch VAS between before and after acupuncture treatment was significant. Among 'obtaining qi(deqi)', subjects reported that 'dull ache', 'pricking', 'heavy' were most strong. Total score of 'obtaining qi(deqi)' sensation was not related to the change of itch VAS or skin flare. The 'electric shock' sensation is related to the change of itch VAS, and 'bruised' and 'heavy' sensations were related to the change of skin flare. Conclusions : Total 'obtaining qi(deqi)' is not related to the anti-itching effect of acupuncture, but several sensations showed relationship with the effect of acupuncture on itch severity and skin flare. Further researches based on various symptoms or acupuncture points, are needed.

Neuropathic pain is a complex state showing increased pain response with dysfunctional inhibitory neurotransmission. The TREK family, one of the two pore domain $K^+$ (K2P) channel subgroups were focused among various mechanisms of neuropathic pain. These channels influence neuronal excitability and are thought to be related in mechano/thermosensation. However, only a little is known about the expression and role of TREK-1 and TREK-2, in neuropathic pain. It is performed to know whether TREK-1 and/or 2 are positively related in dorsal root ganglion (DRG) of a mouse neuropathic pain model, the chronic constriction injury (CCI) model. Following this purpose, Reverse Transcription Polymerase Chain Reaction (RT-PCR) and western blot analyses were performed using mouse DRG of CCI model and compared to the sham surgery group. Immunofluorescence staining of isolectin-B4 (IB4) and TREK were performed. Electrophysiological recordings of single channel currents were analyzed to obtain the information about the channel. Interactions with known TREK activators were tested to confirm the expression. While both TREK-1 and TREK-2 mRNA were significantly overexpressed in DRG of CCI mice, only TREK-1 showed significant increase (~9 fold) in western blot analysis. The TREK-1-like channel recorded in DRG neurons of the CCI mouse showed similar current-voltage relationship and conductance to TREK-1. It was easily activated by low pH solution (pH 6.3), negative pressure, and riluzole. Immunofluorescence images showed the expression of TREK-1 was stronger compared to TREK-2 on IB4 positive neurons. These results suggest that modulation of the TREK-1 channel may have beneficial analgesic effects in neuropathic pain patients.

An 11-month-old, 19.5 kg, intact male Border collie was referred with intermittent left forelimb lameness to the Gyeongsang Animal Medical Center. The symptom was first discovered about 6 months ago, and it has gotten worse for the last 10 days with non-weight bearing on the left forelimb. During the physical examination, the patient showed painful reaction when the left shoulder was abducted. On radiographic assessment, a radiolucent line and some osteophytes were found in both humeral heads. Based on patient's clinical signs and radiographic findings, osteochondritis dissecans (OCD) was very suspicious. So, we decided to perform an arthroscopic surgery on left shoulder for definitive diagnosis and treatment because the right forelimb revealed no clinical signs. During arthroscopic technique, we found a large OCD flap on the caudo-central area of humeral head, and observed severe synovitis over a wide range on posterior area of the articular capsule. The large OCD flap was removed by a grasping forceps, and many joint mice were removed either. Curettage was performed using a curette on the articular surface until hemorrhage occurred, and articular capsule flushed with a lactated-ringer's solution. The patient was discharged on the same day without any specific abnormal status. Antibiotic, anti-inflammatory and analgesic drugs were administered. Mild lameness on left forelimb was observed in 2 weeks after surgery, but after 4 weeks, the patient showed complete normal gait without any lameness. Although surgical removal of OCD flap with arthroscopic was previously reported, We would like note that a large OCD flap can also be removed by arthroscopic surgery in this report.
