최근 우리 나라는 열두조충과 (Diphyllobothridae)에 속하는 조충류의 인체 감염예가 빈번하게 보고되고 있다. 이는 본 조충류의 감염매체인 어류를 날 것으로 생식할 기회가 많으며, 또한 본 조충류의 제1중간숙주인 물벼룩이 음료수를 통한 인체 감염이 원인일 것으로 추정되고 있다. 조충류의 진단은 충체에 있어 두적과 편절의 형태학적 특징을 감별하여 種의 분류와 진단을 하는 것이 기본적 순서가 될 것이나, 1차적으로 가능한 진단은 환자의 증상 참작과 분변으로부터 충란을 발견 감별하게 된다. 특히 광절열두조충류의 충란에 의한 種鑑別은 환자로부터 편절이나 충체의 확실한 감별을 위한 사전 정보를 가늠하는 뜻에서도 중요성이 있다. 이에 저자들은 환자의 치료와 함께 수집된 Diphyllobothrium latum, D. latum parvum 그리고 Spirometra erinacei의 편절과 충란을 재료로 형태 및 진단적 결과를 분석한 바 그 성적은 다음과 같다. 1. 환자의 분변에서 수집된 충란 50개씩을 각각 선택하여 형태와 크기에 대한 계측을 실시하였다. D. latum의 충란은 난개가 있고 난원형 또는 타원형의 모양으로 관찰되었으며 D. latum parvum은 D. latum에 비하여 더 난원형이면서 작게 관찰되었다. S. erinacei의 충란은 폭이 비대칭적이며 길쭉한 모양으로 관찰되었다. 2. D. latum, D. latum parvum 그리고 S. erinacei의 충란의 크기에서 충란의 평균 길이와 폭은 각각 61.4X41.7㎛, 55.9X41.4㎛ 그리고 66.7X36.4㎛이었다. 3. 각 조충의 편절을 고정한 다음, 첫째 포매하고 microtome으로 절편을 만들어 hematoxylin-eosin 염색을 실시하였고, 둘째 고정과 함께 semicon's aceto-carmine 염색표본을 작성하여 현미경 관찰을 한 결과 D. latum과 D. latum parvum은 생식선이 편절의 중앙선상에 위치하고 개구된 자궁구가 관찰되었다. 그리고 편절의 양측에 난황이 follicle로 관찰되었으며 전형적인 rosette모양을 형성하고 있었다. 그러나 D. latum parvum은 D. latum에 비하여 아주 작은 크기로 관찰되었다. S. erinacei의 편절은 자궁이 나선형으로 5∼7회 이상으로 말려서 관찰되었고 음경낭안에서 저정낭이 이어져 연결되고 있었다. 이로써 본 연구에서는 편절의 형태특징과 함께 충란 크기에 대한 계측과 분석을 하고자 하였으며, 공학현미경에 의한 계측치로 세 종류의 조충 감별에 유의한 참고치를 제기하는 바이다. Recently there have been frequent reports on human infection caused by the Diphyllobothridae in Korea. The adequate opportunities for Koreans to eat raw fish, the primary infection medium of cestodes and the human infection through drinking water by cyclops, the first intermediate host are believed to be main reasons for the infection. The first task of this study was to classify and diagnose the species by differentiating morphological characteristic between scolex and proglottids of cestodes. However, the initially available diagnosis was done with the patient's symptoms and the eggs obtained from his stool. It is important to differentiate the species by the eggs of Diphyllobothrium latum especially in that it can help get advance information for a more reliable analysis in the near future. The morphological and diagnostic results from proglottids and eggs of Diphyllobothrium latum, Diphyllobothrium latum parvum and Spirometra erinacei are as follows; In each kind of cestodes from the patient's stool, the shape and size of 50 eggs were measured. Eggs of Diphyllobothrium latum had an operculum and were ovoidal or ellipsoid to elliptical in shape. Eggs of Diphyllobothrium latum parvum were more ovoidal in shape and smaller in size than Diphyllobothrium latum. And eggs of Spirometra erinacei were asymmetrical in width and long and slender in shape. The average lengths and widths of Diphyllobothrium latum, Diphyllobothrium latum parvum and Spirometra erinacei were 61.4X41.7㎛, 55.9X41.4㎛ and 66.7X36.4㎛, respectively. After the segments of each cestode were fixed, embedding and hematoxylin-eosin dyeing on a microtome-made specimen were done. The micrographs of the semicon's aceto-carmine dyed specimen showed that Diphyllobothrium latum and Diphyllobothrium latum parvum had a centrally-located genital gland and an opened uterine pore. The yolks were observed on both sides of proglottids and had a typical rosette pattern. Yet, Diphyllobothrium latum parvum was shown smaller than Diphyllobothrium latum in the micrograph. Proglottids of Spirometra erinacei displayed that the uterus was rolled spirally more than five to seven times, and connected successively to the seminal vesicle in the cirrus sac. Shown above, this study was performed to measure the size of eggs and analyze the morphological characteristics of proglottids and provided the measurements of three types of cestodes obtained by a light microscope.

Mucoepidermoid carcinomas, first reported by Volkman(1895), form 6% to 9% of all salivary tumors. Two thirds affecting the parotid gland and the remaining third, the minor glands. As we could know from its name, mucoepidermoid carcinomas originate from ductal epithelium including squamous, mucous-secreting, and undifferentiated intermediate cells. Histologically, it is classified as well-differentiated (low grade), moderately-differentiated(intermediate grade), and poorly-differentiated (high grade) types and the treatment method and prognosis are influenced from its histological grade. We have experienced two cases of mucoepidermoid carcinoma treated surgically with good results and now would like to report these with review of literatures.

Small bowel volvulus in adults is very rare and occasionally occurs due to congenital midgut malrotation. The most common cause of small bowel volvulus is adhesions (74%), and other causes are Crohn's disease(7%), neoplasia (5%), hernia (2%), radiation (1%), and miscellaneous(11%). Presenting symptoms may be acute or present periodically during a longer period of time with a condition that is intermittent or recurrent because of spontaneous detorsion of the volvulus. Diagnostic imaging studies are plain abdominal film, ultrasonography, abdominal CT, and angiography. Abdominal CT is the most accurate. The most frequent CT finding is "Whirlpool sign." Other findings are bowel-loop dilatation, bowel-wall thickening, beak signs, mesenteric alterations, and extraluminal fluid. The mortality rate associated with small bowel voluvlus in adults is 10~67%. We report a case of small bowel volvulus in adults.

In order to set the distribution pattern and surface area of the mucosal epithelium and submucosal gland in the mice nasal septum. 3-month-old healthy 6 mice weighing 25gm approximately have been contributed for this research. For the mapping of the each nasal epithelium and submucosal gland in the submicroscopic level, the routine paraffin block of the mice nasal septum were cut as the 10㎛ thick at 110㎛ intervals. Consecutive 2 slides were stained with H-E and PAS and reconstructed in form of maps representing the structure in a sagittal plane. The results obtained from this research were summarized as follows. 1. The unilateral nasal surface epithelial area of the mice nasal cavity was 31.23㎟ 2. The areas of the stratified squamous epithelium, respiratory epithelium and olfactory epithelium which compose the unilateral nasal epithelium were 4.47㎟(14.3%), 12.7㎟(40.8%), and 14.02㎟(44.9%), respectively. 3. Submucosal glands in the mice nasal septum were divided into the PAS-positive, PAS-negative and Bowman's glands by the PAS staining. 4. The surface area of the PAS-positive glands in the nasal unilateral septum was 5.23㎟ which is located in the central area of the respiratory portion. 5. The surface area of the PAS-negative glands in the nasal unilateral septum was 5.05㎟ which is located above and below the PAS-positive gland. 6. The surface area of the Bowman's glands was 12.1 ㎟ which was located in the olfactory region. 7. In the vestibular region., 3 ducts of PAS-negative glands of the respiratory region are found, and below the nasal septum there is the infraseptal gland(PAS-negative).

Objective : The aim of this study was to evaluate the treatment result and quality of life (QOL) in patients with intracanalicular to small-sized vestibular schwannoma (VS), who were managed with microsurgery or gamma knife radiosurgery (GKS). Methods : Medical records of 40 patients who were available on the telephone interview and were followed up more than 6 months after treatment for VS of Koss grade 2 or less from 1997 to 2007 were reviewed. Eighteen patients were treated with microsurgery via translabyrinthine approach and 22 patients were treated with GKS. We evaluated tumor control rate, complications and QOL. To evaluate the QOL, we used the Glasgow Benefit Inventory questionnaires with telephone interview. Result : The mean observation time was 26.85 months. Sixteen patients (88.89%) in microsurgery group did not develop recurrence of tumor. Twenty patients (90.91%) in GKS group were controlled with less than 140% volume increase. One patient in microsurgery group had facial nerve palsy (FNP) worse than House-Brackmann (H-B) Grade III at last follow-up, while no patient developed FNP worse than H-B grade III in GKS group. Although GKS group had higher score in GBI questionnaires, the difference was not significant in comparison with microsurgery group. Conclusion : In small VS, microsurgey and GKS showed similar tumor control and complication rate. Microsurgery group did not have worse QOL than GKS group.
