  • Volatile terpenes responsible for allelopathic activity in four weed species were identified using gas chromatography (GC) and GC-mass spectrometry. Artemisia asiatica Nakai contained 26 volatile terpenes, consisting of 16 monoterpenes and 10 sesquiterpenes, whereas there were only four terpenes in Trifolium repens L. and three terpenes each in Portulaca oleracea L. and Capsella bursa-pastoris (L,) Medik. Suspected allelochemics were ${\alpha}$-phellandrene, 1,8-cineole, limonene, ${\alpha}$-pinene, borneol, selinene, and caryophyllene in A. asiatica, ${\alpha}$-pinene and ${\beta}$-caryophyllene in T. repens, and ${\alpha}$-pinene in C. bursapastoris. No these compounds were found in P. oleracea.

  • Livestock husbandry is vital to economy of the Tarim Basin, Xinjiang Autonomous Region, China. However, there have been few surveys of the distribution of ixodid ticks (Acari: Ixodidae) and tick-borne pathogens affecting domestic animals at these locations. In this study, 3,916 adult ixodid ticks infesting domestic animals were collected from 23 sampling sites during 2012-2016. Ticks were identified to species based on morphology, and the identification was confirmed based on mitochondrial 16S and 12S rRNA sequences. Ten tick species belonging to 4 genera were identified, including Rhipicephalus turanicus, Hyalomma anatolicum, Rh. bursa, H. asiaticum asiaticum, and Rh. sanguineus. DNA sequences of Rickettsia spp. (spotted fever group) and Anaplasma spp. were detected in these ticks. Phylogenetic analyses revealed possible existence of undescribed Babesia spp. and Borrelia spp. This study illustrates potential threat to domestic animals and humans from tick-borne pathogens.

  • Extract from forty four species of natural plants in Korea were obtained. Each extinct (1,000 ppm) was added into fish oil and their antioxidative activities were screened by rancimat, From the results, seven species including Brassica juncea, Solanum tuberosum, Capsella bursa, Ulums davidiana, Broussonetia kazinoki, Oenanthe javanica, and Rhus chinensis were selected due to their relatively prolonged induction periods. When the concentration (100 - 1,000 ppm) of the selected extract was considered, the most prolonged induction period was observed from Solanum tuberosum throughout the studied concentrations, suggesting that its extinct showed the strongest antioxidative activity against fish oil. In addition, peroxide value (POV) and thiobarbituric acid reactive substance (TBARS) value were considered at $60^{\circ}C$ for 5 days. Among the selected extract, extract from Solanum tuberosum showed the lout POV while the extract from Brassica juncea var showed the least TBARS values after 5 days. Also, the free radical scavenging effect against DPPH radical were studied with the selected extract, showing that the extract from Rhus chinensis was found to be the most effective.

  • Clinically the arthritis occupies much part of musculoskeletal diseases. The arthritis is subordinate to Bi-jeung in the oriental medicine. No matter what is the cause of the diseases, the lesions of the arthritis are mostly cartilages and bursa. But in process of the depravation bones, muscles, tendons, ligaments and blood are influenced and become new the lesions of the arthritis. it is important that the treatments of the oriental medicine must be objectified and we must absorb a good of the western medical treatments and understand the excellent study of the arthritis in the western medicine. This study was done to comply a reference of 56 master's theses on the cartilage of the western medicine. And these theses were classified by the college, time, treatments and topics. The following results were obtained in this study: 1. Whereas In the theses on the cartilages of the western medicine, Jung-ang and Catholic university have the more theses than any other universities. 2. Analysing the theses on the cartilages of the western medicine, we can classify them by the topics with the influence on the regeneration and culture of the cartilages, observation of the historical structure and the influence on the cartilages by the operation. 3. The theses of the influence on the regeneration and culture of the cartilages were the most, 48%, and the seceond was the influence on the cartilages by the operation.(22%) However the theses on the observation of the historical structure occupied 16%.

  • Fowl cholera is a contagious acute and chronic disease caused by Pasteurella multocida in both domesticated and wild birds. Acute fowl cholera in both chickens and wild birds has recently been documented in Korea, but the chronic form has not been reported in Korea until now. This study describes the first outbreak of chronic fowl cholera in 13-week-old Arbor Acre broiler breeder chickens submitted to the College of Veterinary Medicine, Kyungpook National University in April 2006. The clinical signs of the affected flock of 9,621 chickens were lameness caused by swollen hock joints, diarrhea, ruffled feathers, and an average weekly mortality of 1.0%. At necropsy, purulent or caseous exudates were found in the hock and wing joints, humerus, and eyes, and severe pneumonia and pericarditis were discovered. Eleven bacterial isolates obtained from the liver, joint, infraorbital sinus and sternal bursa of the submitted chickens were all identified as Pasteurella multocida based on their physiological and biochemical characteristics. Five isolates were examined for antimicrobial susceptibility against 21 different antimicrobial agents including ampicillin. All were resistant to kanamycin, neomycin, and streptomycin, and some were resistant to gentamicin. The tested isolates were all susceptible to the other 17 antimicrobial agents. All 11 isolates were capsular serogroup A based on multiplex polymerase chain reaction. In addition, two of five isolates used in the antimicrobial susceptibility test were identified as somatic serotype 1 by an agar gel diffusion precipitin test, while the others were non-typable.

  • Anatomy: The rotator cuff comprises four muscles-the subscapularis, the supraspinatus, the infraspinatus and the teres minor-and their musculotendinous attachments. The subscapularis muscle is innervated by the subscapular nerve and originates on the scapula. It inserts on the lesser tuberosity of the humerus. The supraspinatus and infraspinatus are both innervated by the suprascapular nerve, originate in the scapula and insert on the greater tuberosity. The teres minor is innervated by the axillary nerve, originates on the scapula and inserts on the greater tuberosity. The subacromial space lies underneath the acromion, the coracoid process, the acromioclavicular joint and the coracoacromial ligament. A bursa in the subacromial space provides lubrication for the rotator cuff. Etiology: The space between the undersurface of the acromion and the superior aspect of the humeral head is called the impingement interval. This space is normally narrow and is maximally narrow when the arm is abducted. Any condition that further narrows this space can cause impingement. Impingement can result from extrinsic compression or from loss of competency of the rotator cuff. Syndrome: Neer divided impingement syndrome into three stages. Stage I involves edema and/or hemorrhage. This stage generally occurs in patients less than 25 years of age and is frequently associated with an overuse injury. Generally, at this stage the syndrome is reversible. Stage II is more advanced and tends to occur in patients 25 to 40 years of age. The pathologic changes that are now evident show fibrosis as well as irreversible tendon changes. Stage III generally occurs in patients over 50 years of age and frequently involves a tendon rupture or tear. Stage III is largely a process of attrition and the culmination of fibrosis and tendinosis that have been present for many years. Treatment: In patients with stage I impingement, conservative treatment is often sufficient. Conservative treatment involves resting and stopping the offending activity. It may also involve prolonged physical therapy. Sport and job modifications may be beneficial. Nonsteroidal anti - inflammatory drugs(NSAIDS) and ice treatments can relieve pain. Ice packs applied for 20 minutes three times a day may help. A sling is never used, because adhesive capsulitis can result from immobilization.

  • Purpose: To investigate the clinical features of fistulas of the ankle joints. Materials and Methods: Seven fistulas in seven patients were reviewed during Apr. 2000 to Mar. 2002, retrospectively. There are five men and two wemen. Average age was 47.7 years (range, 42-65 years). Average follow-up period was 1.4 years. There were six cystic lesions after ankle sprain and one patient with persistent discharge after excision of bursa over lateral malleolus. Results: Duration from injury to presentation was average 9.8 years. The site of preoperative swelling was mostly over the lateral malleolus in five patients. In one patient, the area of swelling was extended to the anterolateral ankle joint and in another patient there was extensive swelling from Achilles tendon to the anterolateral ankle joint. Concomitant symptoms were instability in three patients, pain and instability in three patients. Methods of surgery were simple repair in one, modified Brostrom in three, augmentation with periosteal flap in addition to modified Brostrom in two and Chrisman-Snook in addition to augmentation with periosteal flap and modified Brostrom in one. There were no recurrence of instability as well as fistula. Conclusion: We think that the fistula of the ankle joint should be included in the differential diagnosis of the cystic lesion over the lateral malleolus and the result of surgical treatment would be satisfactory in most cases.

  • Objectives: The aim of this study was to evaluate the effects of endodontic treatment on levels of substance P (SP) and calcitonin gene-related peptide (CGRP) in the saliva of patients with symptomatic apical periodontitis. Materials and Methods: Twelve patients with mandibular molars with symptomatic apical periodontitis were enrolled in this study. An initial saliva sample was collected just before administration of anesthesia for root canal treatment, which was performed at the first visit. A second saliva sample was collected at a control visit 1 week after treatment. Salivary SP and CGRP levels were evaluated quantitatively using biochemical assays. The data were analyzed using Pearson correlation analysis, the paired samples t-test, and the Mann-Whitney U test (p = 0.05). Results: The postoperative salivary level of SP was significantly lower than the preoperative level (p = 0.005). However, the postoperative salivary level of CGRP was similar to the preoperative level (p = 0.932). Visual analog scale (VAS) scores of patients' subjective pain were found to be positively correlated with salivary levels of SP (r = 0.421; p = 0.040). No statistically significant correlations were observed between salivary levels of CGRP and VAS scores for patients' subjective percussion tenderness (p = 0.533) or VAS scores for patients' subjective pain (p = 0.459). Conclusions: According to the results of the present study, salivary SP levels may be used as an objective indicator in the diagnosis and assessment of the degree of pain in endodontic diseases.

  • Subcoracoid impingement resulting from abnormal contact between the anterosuperior humerus and the anterior coracoacromial arch represents an uncommon source of anterior shoulder pain. Certain operative procedures can also alter the relationship between the coracoid and the lesser tuberosity, leading to impingement of the interventing soft tissue, including the subscapularis and the bursa. We describe an unique case of subcoracoid impingement with the tear of subscapularis tendon after the internal fixation of the fractured coracoid process with cannulated screw due to crowding of the coracohumeral space. Arthroscopic removal of the screw and repair of the subscapularis in our patient resulted in successful resolution of his symptoms. Although subcoracoid impingement is a rare cause of shoulder pain, failure to diagnose and treat this condition may represent a significant cause of failed shoulder surgery.
