  • A 5-year-old, intact male, poodle dog with right external auditory canal obstruction and subaural mass was presented. Physical examination revealed that right external auditory canal opening was absent and right head tilt was identified. Aspiration in right subaural mass revealed a small amount of dark brown exudate. Streptococcus canis and Staphylococcus spp. were identified on the microbial culture. Radiography of the skull was revealed absence of air-filled ear canal at the right external ear canal (EEC) level. Computed tomography (CT) revealed well capsulated, hypoattenuated mass in the right EEC region. On the contrast enhanced CT images, rim enhancement around the mass and ear canal obstruction were identified. Fluid attenuated material filled with right bulla. Mild thickening of the right tympanic bulla wall with mild lytic lesion of the ventral wall were found. Based on the images findings, the case was tentatively diagnosed as right external auditory canal atresia with otitis media. Total ear canal ablation and lateral bulla osteotomy was performed. The entire ear canal was removed, numerous hair in the canal and the thickening wall were founded. Right ear canal was sent for histopathological evaluation and found to otitis externa. The patient was followed up for two weeks and there were no complications. This report described the CT diagnosis of right EEC atresia with otitis media rarely reported in small breed dogs.

  • Fluor genitalis(帶下) apply to secretions of the vaginal canal except bleeding. These secretions of the vaginal canal are excessive volume of secretions or abnomal conditions which were progressed exudate of diseased genital atrium. The greater parts of flour genitalis are not critically ill. The greater parts of flour genitalis are continuous with simple infections of cervix, vagina and uterine tube. Fluor genitalis is met with everywhere at gynecology disease and is frequently broken out at least one third of women. This study is designed to find best way of evaluation about the clinical treatment effect of fluor genitalis.

  • As a way to revive the traditional technology of Korean golden varnish(Hwangchill), the exudates of D. morbifera, this study was carried out at first to investigate the anatomical characteristics and the chemical composition of D. morbifera stems and their exudates. Trees of more than 20 years old were harvested at Wando and Jejudo islands in the southwestern part of Korean peninsula during different physiological seasons of winter, spring, and summer, The results obtained are as follows: 1. In the anatomical aspect of wood, Hwangchil woods is ring-porous wood, has alternate inter-vessel pittings and horizontal intercellular canal in xylem. 2. In the chemical aspect of wood and bark, the general compositions appeared hot to differ from those of other hardwoods, and ash and alcohol-benzene extractives showed little increase with the increase of atmospheric temperature of harvesting season. 3. In the solvent-sequential extraction of bark, wood and exudate, the exudates was extracted up to 80% by ether, but the bark and wood contained a very small amount of ether extractives, about 2% in the bark and 0.5% in the xylem.

  • Objectives: The aim of this study was to investigate levels of matrix metalloproteinase-8 (MMP-8) and substance P (SP) in root canal exudates during root canal treatment (RCT) of nonvital, painful teeth. Materials and Methods: Patients scheduled for nonsurgical RCT were prospectively selected; the study was performed after obtaining informed consent from the patients and was approved by the Institutional Review Board for Clinical Research of Gangnam Severance Hospital, Yonsei University (3-2008-0118). Canal exudates samples were collected using sterilized paper points from teeth scheduled for RCT across three different time periods. MMP-8 and SP levels were measured using enzyme-linked immunosorbent assay (ELISA). Data were analyzed using a mixed model analysis and the Pearson correlation analysis (p < 0.05). Results: MMP-8 and SP levels in GCF were decreased during RCT (p < 0.0001), and they showed a weak positive correlation to each other (p < 0.05). Patients' subjective pain levels and the response from percussion test were significantly related to SP level. Conclusions: This study demonstrated that periradicular inflammation endodontic origin can elevate SP and MMP-8 levels in root canal exudates. Interestingly, SP level of canal exudates showed a possibility of being used as an indicator of pain due to periapical pathosis.

  • The purpose of this study was to compare Black-pigmented Bacteroides isolated from necrotic pulp with the presence or absence of eight symptoms associated with pulpal necrosis and to identify the proportion of each Black-pigmented Bacteroides species. The canal contents of fourteen traumatically and cariously necrotized teeth were sampled with a special technique and cultured aerobically and anaerobically for growth in blood agar plate and for Black-pigmented Bacteroides on selective blood agar plate. Each Black-pigmented Bacteroides species were identified by Gram's stain, hemolysis reaction, colony color and morphology and biochemical tests. The results were as follows; 1. 60.9 percent of the bacteria isolated were anaerobic and 39.1 percent were aerobic. 2. Four Black-pigmented Bacteroides species were isolated; B. loescheii (74.1%), B. denticola (11.1%), B. intermedius (7.4%) and B. gingivalis (7.4%). 3. Black-pigmented Bacteroides was found to be significantly related to sinus tract formation and exudate.

  • The clinical results of 10 consecutive total ear canal ablation combined with lateral bulla osteotomy (TECA-LBO) in six dogs with chronic otitis externa and media were evaluated by the postoperative recovery and long-term follow-up. All dogs were selected for TECA-LBO on the basis of following five clinical symptoms. First, medical treatment couldnt improve clinical signs at least for eve. 2 months. Second, tympanic membrane was completely disappeared. Third, radiopacity was increased in tympanic cavity. Forth, petrous temporal bone was sclerosed. Fifth, ear canal calcification was progressed. And all cases were satisfied all five clinical symptoms. At 14. days after operation, the preoperative symptoms of chronic otitis externa and media which were scratching ear, pain, and hardening ear canal were resolved, and postoperative swelling, erythema, head tilt, and exudate from Penrose drainage were not existed In all cases. Loss of eye blink was happened in 4 cases, but these were disappeared between 14 days a(ter operation except one case on 3 months. All dogs were discharged form hospital at 14 days after operation. Between 3.5 and 6.5 months after discharging from hospital, para-aural abscessation was happened only in all Cocker spaniels. But this complication was solved by ventral bulla osteotomy (VBO). The dogs which didn't show para-aural abscessation after TECA-LBO didn't show scratching, pain, hardening of ear and hearing ability was improved, at 7.5 months after TECA-LBO. And the dogs which showed para-aural abscessation after TECA-LBO also didn't show scratching, pain, hardening of ear and hearing ability was also improved, at 7.5 months after VBO. In conclusion, After TECA-LBO, all dogs were recovered well without complication within 2 weeks except Cocker spaniel. And loss of eye blink can be cured naturally within 2 weeks after surgery. And para-aural abscessation can be happened between 4 and 7 months after TECA-LBO, so surgeon must follow-up until 8 months.

  • This study was conducted to find optimum pollination methods for overcoming pre-fertilization incompatibility in interspecific crosses between L. longiflorum 'Gelria' (LG) and L. cernuum (LC). In cross combination of $LC{\times}LG$, the survival rate of the ovaries was higher in the cut style pollinations than in normal stigmatic pollination. Among the various cut style pollination methods, pollination after cutting the styles 2 3mm length above the ovary and top of the ovary were the most effective ones. No ovaries and ovules survived in cross pollination of $LC{\times}LG$. In self-pollination of LG and cross pollination of $LC{\times}LG$, pollens germinated on the stigma by 12 hours and reached to the ovules by 90 hours after pollination. However, in the cross pollination of $LC{\times}LG$, pollen tubes elongated very slowly until 48 hours after pollination and a lot of deformed tubes were observed in the styler canal having swelled tube tip and irregular heavy callose deposition. The pollination time after anthesis also affected on the survival rate of ovaries and ovules showing the best result when pollinated on three days after anthesis. Stigma exudate promoted slightly the enlargement of ovaries, but the survival rate of ovaries and ovules was not increased.
