Infections of Intestinal Helminth at Two Species of Field Mice, Apodemus agrarius and A. Peninsulae, in Gangwondo and Chungcheongnam-do, Korea

Rodents are important reservoirs of diseases affecting people and livestock, and are major sources of parasite contamination of agricultural products. We surveyed the infection status of intestinal helminths in 2 species of field mice, Apodemus agrarius and A. peninsulae, captured in the agricultural fields of Gangwon-do and Chungcheongnam-do, Korea. Total 83 mice (57 A. agrarius and 26 A. peninsulae) were collected in 2 surveyed areas, and the intestines of each mouse were opened with scissors, and then intestinal contents were examined with microscope. Total 6 species of intestinal helminth were detected in 61 (73.5%) out of 83 mice examined. Four species of nematode, i.e., Nippostrongylus brasiliensis, Aspiculuris tetraptera, Heterakis spp. and ascarid, were found in 40 (48.2%), 14 (16.9%), 11 (13.3%) and 13 (15.7%) mice respectively. One species of cestode, Hymenolepis diminuta and 1 unidentified egg were also detected in the intestines of 14 (16.9%) and 1 (1.2%) mice, respectively. Conclusively, this study identified 5 helminth species in the gastrointestinal tracts of wild rodents captured in some areas in central and northern Korea, and N. brasiliensis was the most prevalent (dominant) species rather than zoonotic ones.

A Clinical Study of Laryngeal Intubation Granuloma / 대한마취과학회지

Twenty cases of laryngeal intubation granuloms were diagnosed during the three year period from July, 1984 to December, 1987 at the Department of Otolaryngology and Anesthesiology, Guro Hospital, College of Medicine, Korea University. Among the twenty cases, nine had previous operation at the same hospital, where 14,866 cases of endotracheal anesthesia were performed during the period. A clinical analysis of these cases was made to obtain observations as follows: 1) Twenty cases were all female. 2) Nineteen cases were adults with ages ranging from 19 to 71 years, and one case was an 8 year old who had undergone open heart surgery. 3) In 7 cases which comprises about 30% of all surgery had been performed on the head and neck area. The durations of endotracheal intubation for those cases were variable ranging from 55 minutes to 75 hours. 4) The site of the granuloma was the vocal process of the arytenold cartilages in 19 patients. In 7 patients the granuloma observed were bilateral, in 7 on the left side, and in 6 on the right side. 5) The chief complaints of the granuloma patients were hoarsness in 18 patients, respiratory difficulty in 10 patients, and foreign body sensation in 4 patients. 6) These proven cases were all treated by removal of the granuloma under suspension laryngoscopy. The results were excellent except for one case which showed recurrence in 3 months.
