Objectives & Methods : The objective of this study was to evaluate the single oral dose toxicity of Chongmyung-tang (CMT) in ICR mice. Korean traditional herbal prescription CMT has traditionally been used as a neuroprotective for treatment of learning disability and memory improvement. CMT, lyophilized aqueous extracts (yield=9.7%) were administered to female and male mice with oral dose of 2,000, 1,000 and 500 mg/kg (body weight) according to the recommendation of Korea Food and Drug Administration (KFDA) Guidelines. Animals were monitored for mortality, changes in body weight, clinical signs and gross observation during 14 days after administration upon necropsy; organ weight and histopathology of 14 principle organs were examined. Results : We could not find any CMT extracts treatment related mortalities, clinical signs, changes in body and organ weight, or gross and histopathological observations against 14 principle organs up to 2,000 mg/kg in both female and male mice, except for some accidental sporadic findings which did not show any obvious dose-relations and most of which also demonstrated in both the female and male vehicle control mice in this experiments. Conclusions : Based on the results of this experiment, the 50% lethal dose ($LD_{50}$) and approximate lethal dose (ALD) of CMT extracts after single oral treatment in female and male mice can be considered to be over 2,000 mg/kg, and is likely to be safe in humans.

To avoid external facial scar which resulted from ordinary infraorbital and lateral eyebrow incision in surgical treatment of zygomatic tripod fractures, the author used intraoral incision and K-wire fixation method in 37 selected patients. This method contraindicated for the patient with multiple comminuted zygomatic fracture, patient combined with hard palatal fracture, and patient combined with herniated orbital floor fracture. The advantages of this method are simple, no external facial scar, and operate under direct visual field. The postoperative results were satisfactory. Balanced facial symmetry and good cosmetic results were obtained.

Pleomonhic adenoma, the most common of the benign salivary gland tumor, is called benign mixed tumor. The tumor was first described by Kaltschmied in 1725 and clinically systematized by Bilroth in 1859. Most pleomorphic adenoma arise in major salivary glands. However, their development in minor salivay glands of the oral cavity, pharynx, paranasal sinuses, and in skin and lacrimal glands is well known. The palate is the most common site of origin of pleomorphic adenoma in minor salivary gland. Recently the authors have experienced a case of the huge pleomorphic adenoma of the hard palate in a 70 years old woman. This is the report of a case with review of literature.

Purpose: The standard protocol using large volume of oral contrast media may cause gastrointestinal discomfort and contrast-related artifacts in PET/CT. The aim of this study was to evaluate the usefulness of low dose oral contrast in $^{18}F-FDG$ PET/CT. Materials and Methods: We retrospectively reviewed the whole-body PET/CT images in a total of 435 patients. About 200 ml of oval contrast agent (barium sulfate) was administered immediately before injection of $^{18}F-FDG$. The FDG uptake of intestines was analyzed by visual and semi- quantitative method on transaxial, coronal and saggital planes. Results: Seventy (16%, 113 sites) of 435 images showed high FDG uptake (peak SUV > 4); 50 (74%, 84 sites) with diffuse and 20 (15%, 29 sites) with focal uptake. The most commonly delivered site of oral contrast media was small bowel (n=27, 39%). On PET/CT images, FDG uptake coexisted with oral contrast media in 26 patients (54%, 38 sites) with diffuse pattern and 9 (45%, 9 sites) with focal pattern, and by sites, those were 38 (45%) and 9 (31%), respectively. In small bowel regions, the proportion of coexistence reached as high as 61% (29/47 sites). A visual analysis of available non-attenuation corrected PET images of 27 matched regions revealed no contrast-related artifact. Conclusion: We concluded that the application of low dose contrast media could be helpful in the evaluation of abdominal uptake in the FDG PET/CT image.

Maxillectomy is performed to remove the tumor in the palate, maxillary sinus, buccal mucosa or nasal cavity. The resection range depends on the size and the extent of the tumor and it affects speech production or cause nasal regurgitation during feeding. Obturator can occlude an opening such as an oro-nasal fistula and protect the defect area. Successful reconstrucion of the patient's oral cavity who have gone over the maxillectomy is a difficult task. The condition and number of teeth, the remaining support area, and the extent of the defect area have a great influence on manufacturing the obturator. If these factors are disadvantageous, the prognosis of the prosthesis is uncertain. The final obturator must have a sufficient retention in the patient's oral cavity and must not irritate the surrounding tissue and support area where the resection was performed.In this case, a 55 year old female went through the maxillectomy and the only 3 teeth remained. And the retention of the maxillary prosthesis seems to be poor. So that, we fabricated the closed hollow obturator which has reduced weight compared to the conventional obturator. Consequently the closed hollow obturator can give better sealing and the adaptation.

Dendroaspis natriuretic peptide (DNP), a fourth member of the natriuretic peptide isolated from the venom of the Dendroaspis angusticeps snake, has been reported to be present in human plasma and atrial myocardium and caused vasorelaxation and diuresis in experimental animals. However, it is uncertain whether they are present in peripheral organs other than the heart and its further physiological roles also remains to be clarified. To assess the possible physiological role of DNP in the salivary glands, I investigated the localization of DNP peptide in the rat salivary glands by immunohistochemistry and the binding sites for radiolabelled DNP in the rat salivary glands and oral mucosa using in vitro autoradiography. DNP immunoreactivity was widely distributed in the submandibular, sublingual and parotid glands, particularly in the ducts such as the intercalated and striated ducts, where atrial natriuretic peptide (ANP) was colocalized in consecutive sections, but not in acini. High density $^{125}I-DNP$ binding sites were localized in the epithelia of the tongue and hard palate, while low density binding sites for $^{125}I-DNP$ were also distributed in the submandibular, sublingual, and parotid glands. In the hard palate and tongue, the precise location of this binding was revealed on the basal and parabasal cells of the epithelia by emulsion microautoradiography. These results suggest that DNP may not only have a role in the salivary glands but also play a role in the regulation of growth in the oral epithelium, particularly in the hard palate and tongue.

난치성 전신성 모낭충증에 감염되어 약 4개월간 모낭충 치료제인 amitraz(0.0125%) 처치에도 불구하고 치유되지 않은 한국산 풍산개 2두에 대한 ivermectin 및 amitraz 의 병용치료효과를 알아보았다. 전신성 모낭충증은 신체의 50% 또는 4개의 발에 모두 모낭충 이 검출된 것으로 정의하였다. 내원시 신체검사, 심장사상충검사 및 최소 裂訃위에 대한 피부 박리검사를 실시하여 모낭충을 진단하였고 치료는 돼지용 ivermectin을 체중 kg당 0.5 mg을 피하로 매일 주사하였으며 1주일에 2회 amitraz 약욕을 실시하였다. 피부농피중은 cephalexin 20 mg/kg을 경구로 일일 2회 투여하여 치료하였다. 치료후 4주에 피부병변이 치유되기 시 작하였으며 6주에는 탈모 및 소수의 발진을 제외하고는 피부병변이 정상으로 회복하였다. 피 부박리검사는 6주에 모낭충이 검출되지 않았다. 이들 제제에 의한 부작용은 관찰되지 않았으며 매일 ivermectin 투여와 amitraz 약욕치료의 병용치료는 amitraz로 치료가 되지 않는 난치성의 전신성 모낭충증에 대한 치료기간을 단축시키는 효과적인 치료방법으로 생각된다.
