A 45-year-old man presented with fatigue and weight loss underwent a Tc-99m MDP bone scan because of increased serum alkaline phosphatase. Delayed images at 4 hours demonstrated diffuse increased activity throughout both lobes of the thyroid in the absence of activity of the stomach and salivary glands. Thyroid laboratory indices and a Tc-99m pertechnetate thyroid scan suggested Graves' hyperthyroidism.

The experimental female rats were ovariectomized and after 14day, they were injected intramuscullarly with estrogen of single dose, 2/100gm body weight. After hormone injection, the animals were sacrificed by ether inhalation, the salivary glands were removed for microscopic examination and the histochemical preparations were observed. The results were as followed; In the submaxillary gland of ovariectomized rats, the acinar cells have lesser PAS reactivity than control group, and-SH group reaction were slight. In the estrogen injected-ovariectomized rats, aciner cells and striated duct cells have high reactivities for PAS, and-SS and SH group reaction were more increased than control group.

Lung cancer is one of the most disastrous of all the current cancers in Korea. In 1990 it was projected that there would be 5, 500 new lung cancer patients in Korea and that 5, 000 would die of their disease. This is a mortality rate of 91 percent. We reviewed the surgically treated 153 bronchogenic cancer patients from January 1987 to December 1991 in St. Mary`s Hospital of Catholic University Medical College. There were 121 men and 32 women ranging in age from 18 to 83 years, with a mean of 56 years. Of the 153 patients, resection was possible in 138 patients and the resectability was 90.1 percent. Squamous cell carcinoma was present in 48 percent of patients, adenocarcinoma in 29 percent, adenosquamous carcinoma in 7 percent, large cell carcinoma in 6 percent, salivary gland tumor in 5 percent, and small cell carcinoma and carcinoid in 3 percent respectively. Postoperative cancer staging was grouped stage I 33 percent, stage II 21 percent, stage IIIa 35 percent, and stage IIIb 10 percent. Lobectomy was performed in 70 percent, pneumonectomy in 17 percent, and segmentectomy in 14 percent. Three and 5-year postoperative survival in resectable 138 patients were 47 and 29 percent respectively.

Fine needle aspiration cytology (FNAC) is an easy convenient non-invasive method in the diagnosis of superficial palpable masses. The cytologic findings by FNAC of reactive and neoplastic lesions in various organs including breast, lymph node, thyroid, salivary gland, etc., have been described, but, those of soft tissue lesions including proliferative fasciitis are relatively rare to find. We recently experienced a case of FNAC of proliferative fasciitis in the left back of a 72-year-old male. The FNAC smears were scant in cellularity and contained large cells with abundant basophilic cytoplasm, one to two nuclei lying at the periphery, and prominent nucleoli that resemble ganglion cells.

This research aims to study the changes In gastrointestinal function attributed to aging In human. The thresholds for recognition and detection of flavors became elevated and salivary gland acinar cells decreased in the old age. But most esophageal function remained relatively Intact. Although gastric emptying time has been slowed with aging, the total intestinal transit time did not differ. Atropic gastritis due to H. pylori in old man decreased secretion of acid and Intrinsic factor and absorbability of calcium and iron. Pancreatic secretion is droned in older persons. Prevalence of gallstones rised with age. Liver size and portal blood flow decreased significantly with age. Mucosal surface area has been reported to be slightly diminished in the aging man. Glucose transporters decreased and Insulin tolerance Increased. Absorption of aromatic amino acid is diminished with age. Dietary protein In that aging human increased fecal nitrogen excretion. Vitamin A tolerance increased. Vitamin D receptor concentration decreased and resistance to 1,25-(OH)2D3 action increased. Permeability of aging small Intestine Increased. Zinc balance dirt not differ Copper absorption appeared not to be significantly affected by age. Neurotensin secretion decreased thus slowed colonic peristaltic movements and Intestinal mucosal growth.

골수외 형질세포종은 아주 드물게 발생하는 종양으로, 전체 형질 세포 종양의 3~5 %를 차지하며 상부 호흡기관에서 주로 발생한다. 그 외 드물게 위장관, 방광, 중추 신경계, 유방, 갑상선, 고환, 타액선, 임파선, 피부 등에서 발생한 증례보고가 있다. 저자들은 49세 남자의 대둔근에서 발생한 골수외 형질세포종 1예를 경험하였기에 이를 문헌 고찰과 함께 보고하는 바이다.

Orocutaneous fistulas, or cutaneous sinuses of odontogenic origin, are uncommon but often misdiagnosed as skin lesions unrelated to dental origin by physicians. Accurate diagnosis and use of correct investigative modalities are important because orocutaneous fistulas are easily confused for skin or bone tumors, osteomyelitis, infected cysts, salivary gland fistulas, and other pathologies. The aim of this study is to present our experience with a patient with orocutaneous fistulas of odontogenic origin presenting as recurrent pyogenic granuloma of the cheek, and to discuss their successful treatment.

Kimura disease (KD) is a chronic inflammatory disorder that frequently involves the subcutaneous tissue of the head and neck regions. It often manifests as regional lymphadenopathy or salivary gland enlargement in the affected area. The histologic architecture of the lymph nodes in KD patients is preserved, while the affected tissues show follicular hyperplasia and eosinophilic infiltration. No single modality has been adopted as an optimal treatment for KD. This article concentrates on the fundamental features of KD and reviews current approaches to its treatment.

Schwannomas are benign tumors originating from myelinating cells constituting nerve sheaths but rarely contain cellular elements of the nerve. The authors encountered a 47-year-old female patient with a schwannoma on the anterior mandibular ramus arising from the buccal nerve, measuring 3 cm×4 cm. Surgical resection was performed with preservation of the buccal nerve via microsurgical dissection. After one month, the sensory function of the buccal nerve was recovered without complications.

Sjögren's syndrome (SS) is an autoimmune disease characterized by dryness of the mouth and eyes. The glandular dysfunction in SS involves not only T cell-mediated destruction of the glands but also autoantibodies against the type 3 muscarinic acetylcholine receptor or aquaporin 5 (AQP5) that interfere with the secretion process. Studies on the breakage of tolerance and induction of autoantibodies to these autoantigens could benefit SS patients. To break tolerance, we utilized a PmE-L peptide derived from the AQP5-homologous aquaporin of Prevotella melaninogenica (PmAqp) that contained both a B cell "E" epitope and a T cell epitope. Repeated subcutaneous immunization of C57BL/6 mice with the PmE-L peptide efficiently induced the production of Abs against the "E" epitope of mouse/human AQP5 (AQP5E), and we aimed to characterize the antigen specificity, the sequences of AQP5E-specific B cell receptors, and salivary gland phenotypes of these mice. Sera containing anti-AQP5E IgG not only stained mouse Aqp5 expressed in the submandibular glands but also detected PmApq and PmE-L by immunoblotting, suggesting molecular mimicry. Characterization of the AQP5E-specific autoantibodies selected from the screening of phage display Ab libraries and mapping of the B cell receptor repertoires revealed that the AQP5E-specific B cells acquired the ability to bind to the Ag through cumulative somatic hypermutation. Importantly, animals with anti-AQP5E Abs had decreased salivary flow rates without immune cell infiltration into the salivary glands. This model will be useful for investigating the role of anti-AQP5 autoantibodies in glandular dysfunction in SS and testing new therapeutics targeting autoantibody production.
