Objectives: This study was designed to analyze the treatment effects of Eunhwayeongyo-tang through retrospective chart reviews. We also checked the correlation between each pair of variables of the symptoms and curative rates of patients with cough. Methods: Thirty-three patients with cough who had satisfied the selection criteria were retrospectively reviewed through their basic medical records, nasal endoscopy, and questionnaires about cough on their first and second visits. The questionnaires used were "The questionnaire on clinical symptoms of cough & sputum", Leicester Cough Questionnaire Korean Version (LCQ-K), Total Nasal Symptom Scores (TNSS), Visual Analog Scale (VAS), and "Cold-heat patterns". The improvement rate, calculated by "The questionnaire on clinical symptoms of cough & sputum" was considered to be clinically effective if reduction of symptoms scored more than 30%. The state of nasopharyngeal mucosa was assessed to categorize the cold-heat patterns of the upper respiratory tract and for diagnosis. Results: According to this study, cough and sputum improved by $57.22{\pm}37.76%$. Most patients (76%) improved significantly after $12.18{\pm}6.59days$ of taking Eunhwayeongyo-tang. The cure rates of 26 patients among the 33 patients were judged as effective. All the mean scores of the questionnaires and the anterior nasal cavity states were significantly improved on the patients' second visits. After $18.39{\pm}15.68days$, 30 patients were completely cured and ended treatment. The nasopharyngeal mucosa states of all patients were categorized as heat patterns. Conclusions: The conditions of the patients with nasopharyngitis significantly improved after taking Eunhwayeongyo-tang. All of the patients had pharyngitis or rhinitis. The cold-heat pattern of nasopharyngeal mucosa was a significant indicator of upper respiratory inflammation diagnosis.

Abnormal gastric emptying time of dog by alien substance, neoplasm, pyloric antrum hyperplasia, stomach surgery, electrolyte imbalance, stomach-dilated torsion is clinically important as a digestive disease. Therefore study aims to provide basic data on the clinical usefulness of gastric emptying time test which uses radiopaque Kolomark developed in Korea rather than using the existing BIPS for the dog. 9 beagles were used for this experiment and their average weight was about 10.3kg with 2.5 year-old average age. For the test, fast for 12 hours was made without chemical sedation, and just before the test, 1 capsule of Kolomark was fed with 25% of daily feed amount, and we took photographs at ventrodorsal and right lateral position after 2, 4, 8 and 12 hours. As for interested reading area, we observed entire stomach from cardia to stomach pyloric part, and as for analysis method, we counted Kolomarks remained in the stomach per time and judged only P value below 0.05 to be meaningful by using Friedman Test. After feeding Kolomark through oral cavity, it took average 7.55 hours for the Kolomark to have escaped from the stomach to small intestine. In this study of gastrointestinal tract passing time after feeding matured dog, we used Kolomark and expect that it could be a basic data for normal gastrokinetic time.

In order to know the species and frequency of human parasitic infection diagnosed by biopsy, 149 cases (0.18%) of parasitic infection were reviewed, which were selected from 80,947 biopsied materials submitted for routine histopathological examination during a period of 10 years from 1980 to 1989 at Department of Pathology, Chonnam National University Hospital. They consisted of 112 cases of cysticercosis, 17 paragonimiasis, 7 clonorchiasis, 4 amebiasis, 1 sparganosis, 1 enterobiasis, 1 anisakiasis, and 1 fascioliasis respectively Based on morphological preservation of cysticercus, they could be divided into mild (20.2%), moderate (40.4%), and severe (39.4%) degeneration. Except 2 cases biopsied at the lungs, 15 cases of ectopic paragonimiasis were located at abdominal cavity (8 cases) and central nervous system (7 cases). One case of intrahepatic fascioliasis was observed. This is the 13th human fasciollasis reported in Korea. From the above results, the frequency of parasitic infections found in biopsied specimens was on the decrease as the year passed by, but biopsy is very useful diagnostic method on tissue parasites such as cystlcercosis and ectopic paragonimiasis.

Objectives : The usage of acupuncture has gained popularity as an alternative method of treatment for certain chronic pain conditions. However, the efficacy of acupuncture in various diseases has not been fully established and the underlying mechanism is not clearly understood. In the present study, the effect of electroacupuncture (EA) applied to foot samli$(ST_{36})$ on the carrageenan-induced knee arthritic pain was examined. Methods : A common source of persistent pain in humans is the knee arthritis. Knee arthritis was induced by injection of 2 % carrageenan $50\;{\mu}l$ into the knee joint cavity. When rats developed pain behaviors, EA was applied for 30 min. under enflurane anesthesia with repeated train stimuli at the intensity of 10X of muscle twitch threshold. The weight bearing force of the hind limb was measured for an indicator of pain level after each manipulation. Results : The average weight borne by the hind limb during normal gait was 55% of total body weight, which was reduced to less than 10% after knee arthritis. EA improved the weight bearing of the arthritic hind limb significantly for the duration of 4 hr. EA applied to $ST_{36}$ point produced a significant improvement of stepping force of the arthritic foot lasting for at least 4 h. However, $GB_{31}$ point did not produce any significant increase of weight bearing force. The analgesic effect was specific to the acupuncture point since the analgesic effect on the knee arthritis model could not be mimicked by EA applied to a nearby point, $GB_{31}$. The relations between EA-induced analgesia and endogenous nitric oxide(NO) and inducible NO synthase(iNOS)/neuronal NOS was also examined. Results were turned out that both NO production and nNOS/iNOS protein expression which is increased by arthritis were suppressed by EA stimulation applied to $ST_{36}$ point. Conclusions : The data suggest 1) that EA produces a potent analgesic effect on the rat model of chronic knee arthritis pain in a point specific manner and 2) that EA-induced analgesia modulate endogenous NO through the suppression of nNOS/iNOS protein expression.

Objectives : We examined mutual inhibitory effects of combined acupoints in arthritic pain induce by carrageenan(CA). Electroacupuncture(EA) is considered a potentially useful treatment for arthritis. Although the analgesic effect of acupuncture is well documented, little is understood about its biological basis. There are many previous studies of positive effect of combined acupoint, this study was conducted to see the mutual inhibitory effects produced by combined acupoint(ST36 and PC7) on arthritic rats. Methods : For the induction of inflammatory pain rat model, CA was injected into the knee joint cavity. There are four groups; EA was applied to bilateral PC7 acupoints(PC7 group), ST36 acupoints(ST36 group), and both PC7 and ST36 acupoints(ST36+PC7 group) except for the control group. The pain level were assessed to determine the change in weight bearing force. We also examined the COX-2 expression in dorsal horn using immunohistochemistry and western blot analysis. Results : The ST36+PC7 group data showed the significant reduction of weight bearing force and the induction of COX-2 protein expression compared with the ST36 group. Conclusions : Simultaneous EA applied to the ST36 and PC7 acupoints reduced the analgesic effect of the ST36 group on knee inflammatory pain.

Objective: The objective of this study was to establish the diagnostic accuracy, specificity and sensitivity of fine needle aspiration cytology(FNAC) for intra-oral tumors, comparing with histopathology as the gold standard. Materials and methods: Forty cases of FNA cytology from intraoral tumors was performed in AFID along with the demographic data and clinical information and then diagnosed at AFIP, Rawalpindi. Then the cytology results obtained per FNAC were compared with the histopathological biopsy results of the same lesions. The following variables were recorded for each patient: Age, gender, site of biopsy, diagnosis. The data were entered and analyzed using Open-epi version 2.0. Diagnostic accuracy, sensitivity, specificity, positive predictive value and negative predictive value were calculated. Cohen Kappa was further applied to compare the agreement between the biopsy and FNAC diagnoses. A p-value of < 0.05 was considered as statistically significant. Results: Among the total patients included in the study there were 24 males and 16 females, with a ratio of 1.5:1. Age of the patients ranged from 24 to 80 years with a mean of 52 years. A total of six sites were aspirated from the oral cavity with maximum (11) aspirates taken from alveolar ridge. The results of FNAC revealed that there were 32 malignant and 8 benign aspirates. Confirmation through histopathological analysis came for 31/32 malignant cases while one was falsely given positive for malignancy on FNAC. Among a total of 40 cases, 31(77%) cases diagnosed were found to be malignant and remaining 9(23%) were benign. The FNAC results revealed 32 malignant and 8 benign lesions. Histopathology of the subsequent surgically excised specimen showed malignant lesions in 31(77%) and benign in 9(23%) patients. As a whole, it was found that the absolute sensitivity for introral FNAC was 100% and specificity 89% with positive predictive value of 97% and negative predictive value of 100%. Conclusion: Cytological diagnosis was almost corroborative with final histopathological diagnosis in all cases, with very few exceptions, exhibiting high diagnostic accuracy.

Background: Tobacco products continue to be used in large quantities in India despite the mandatory inclusion of pictorial health warnings (PHWs) on all tobacco packaging. The circumstances as to how people could continue the use of tobacco to the point of developing head and neck cancer despite enhanced awareness about the ill effects of tobacco is the main focus of this study. Materials and Methods: This study concerned patients with least 5-years history of tobacco use, having been diagnosed with histopathologically proven malignancies of the hypopharynx, larynx, oropharynx and oral cavity presenting at the Government Medical College-Haldwani, Nainital, India. A total of 183 patients were eligible for inclusion during July 1 2013 - June 30 2014. Of these, 59 patients used smoked tobacco exclusively, 22 patients used smokeless tobacco exclusively, and 102 patients used both forms of tobacco. Among users of smoked forms, 75.2% (n=121) were beedi users, and 24.8% (n=40) were cigarette users. Patients were asked direct questions as to whether they had noticed the presence of PHWs upon tobacco products. The reasons as to why PHWs were not effective in stopping the patients from tobacco use were investigated. Results: Of the 183 patients, 146 reported being aware about the presence of PHWs, and when they were asked reasons as to why they continued tobacco despite being aware of ill-effects, the commonest reason chosen (by 53.4%) was that patients had not regarded themselves as using tobacco heavy enough to cause cancer. Among the 36 patients who reported as being oblivious to the presence of PHWs on tobacco products, 63.9% reported that the products they used never displayed any PHWs, and 36.1% reported never having paid attention to the packaging. The awareness about PHWs was higher among cigarette smokers in comparison to beedi smokers (100% vs 76.1%, p=0.0002). Conclusions: Locally produced and marketed tobacco products such as beedis and oral tobacco often fail to display PHWs. The presence of PHWs without doubt enhances awareness about the carcinogenic risks of tobacco. However, enhanced awareness alone may not be enough, and as elucidated by this study, some persons continue to use tobacco to the point of developing malignancies. The need of the hour is the implementation of legal and economic sanctions discouraging the use of tobacco products.

New crown ether dye-Ⅰ and dye-Ⅱ having an azo group(-N=N-) were synthesized from monobenzo-15-crown-5 and dibenzo-18-crown-6. These dyes showed ${\lambda}_{max}$ of 377 and 383nm respectively. The complexes of alkali metal ions ($Na^+$, $K^+$, $Cs^+$) with dye ligands showed band shift (390~400nm) and intensity increased. For a given anion, the extraction constants are in the order of $K^+$ < $Cs^+$ < $Na^+$ for dye-Ⅰ and $Cs^+$ < $Na^+$ < $K^+$ for dye-Ⅱ. These results show that the selectivity of crown ethers toward the alkali metal ions is dependant on the charge density of cation and the size of crown ether cavity. For a given cation, the order of the extraction constant is $Cl^-$ < $Br^-$ < $I^-$ < picrate. This order coincides with the degree of anion solvation effect.

Daily stress is emerging as one of major problems to affect oral health in complicated and diversified modern society. The purpose of this study was to examine the influence of the daily stress of adults on their oral symptoms. The subjects in this study were 460 adults, on whom a survey was conducted from July 1 to October 30, 2012. The findings of the study were as follows: As to the impact of daily stress on oral symptoms, symptoms of the lips and cheeks and symptoms of the tongue were under the significant influence of physical, behavioral and psychoemotional stress. Physical and psychoemotional stress had a significant impact on symptoms of the teeth and the gums, and temporomandibular symptoms were significantly affected by psychoemotional and physical stress. The findings of the study showed that daily stress exerted a larger influence on the lips, cheeks and mucous membrane of oral cavity, and that multiple oral diseases took place when there were not only physical and psychoemotional stress but behavioral stress.

Objective: To investigate the association between endometriosis and polymorphisms of N-acetyl transferase 2 (NAT2), glutathione S-transferase M1 (GSTM1), and cytochrome P450 (CYP) 1A1 genes in Korean infertile patients. Materials and Methods: A total of 303 infertile patients who had undertaken diagnostic laparoscopy during January, 2001 through December, 2003 at Samsung Cheil Hospital enrolled in this study. The patients were grouped according to laparoscopic findings: minimal to mild endometriosis (group I: n=147), moderate to severe endometriosis (group II: n=57), normal pelvic cavity (n=99). Peripheral blood was obtained and genomic DNA was extracted. The genotypes of each genes were analyzed using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP). For NAT2, RFLP was used to detect the wild type (wt) and mutant (mt) alleles, enabling classification into slow (mt/mt) or fast (wt/wt or wt/mt) acetylation genotypes. For GSTM1, PCR was used to distinguish active (+/- or +/+) from null (-/-) genotypes. For CYP1A1, MspI digestion was used to detect the wild type (A1A1), heterozygote (A1A2) or mutant (A2A2) genotypes. Result: The genotype frequencies of NAT2 slow acetylator was 12.8%, 10.9%, 12.8% in group I, group II and control, respectively. The genotype frequencies of GSTM1 null mutation was 55.3%, 41.8%, 53.2% in group I, group II and control, respectively. The genotype frequencies of CYP1A1 MspI polymorphism was 16.3%, 9.1%, 18.1% in group I, group II and control, respectively. No significant difference was observed between endometriosis and normal controls in the genotype frequencies of the NAT2, GSTM1, CYP1A1 MspI polymorphism. Conclusion: The NAT2, GSTM1, CYP1A1 gene polymorphism may not be associated with the susceptibility of endometriosis in Korean women.
