One of the chief characteristics of the retrovirus life cycle is the appearance of provirus caused by integration of viral genome into the host cell genome, and its delivery stably to the next generation as a part of host germ line. This stable form is called endogenous retrovirus (ERV) and expressed by exogenous or endogenous factors. HERVs and MuERVs are present in humans and mice correspondingly, and their expressions frequently cause diseases. Several diseases such as cancer, autoimmunity and neurological disorders are related with HERVs. Therefore, various strategies should be established for the development of effective therapies for the suffering patients.

Objectives: This study aimed to introduce a clinical case of asymptomatic microhematuria due to suspicion of kidney trauma following a motor vehicle accident. Methods: A 19-year-old male was hospitalized with the chief complaint of back pain after a motor vehicle accident. He showed an elevated urine red blood cell (RBC) level in the laboratory test, although no specific traumatic lesions were present on the body. He was assessed to have asymptomatic microhematuria, and Zhu Ling Tang (polyporus decoction) was given to him to be taken three times daily. Results: After the treatment, the level of urine red blood cells returned to normal range. Adverse events were not observed. Conclusions: Zhu Ling Tang caused a short-term improvement in the urinalysis levels of a patient with asymptomatic hematuria. However, further studies are needed, as this study is only a single-case report.

This study aimed to describe a rare case of gnathostomiasis in the vocal cord. A 54-yearold Chinese woman living in Korea visited with a chief complaint of voice change at the outpatient department of otorhinolaryngology in Hallym Sacred Heart Hospital, Hallym University on August 2, 2021. She had eaten raw conger a few weeks before the voice change developed, but her medical history and physical examinations demonstrated neither gastrointestinal symptoms nor other health problems. A round and red cystic lesion, recognized in the anterior part of the right vocal cord, was removed using forceps and scissors through laryngeal microsurgery. The histopathological specimen of the cyst revealed 3 cross-sections of a nematode larva in the lumen of the cyst wall composed of inflammatory cells and fibrotic tissues. They differ in diameter, from 190 ㎛ to 235 ㎛. They showed characteristic cuticular layers with tegumental spines, somatic muscle layers, and gastrointestinal tracts such as the esophagus and intestine. Notably, intestinal sections consisted of 27-28 lining cells containing 0-4 nuclei per cell. We tentatively identified the nematode larva recovered from the vocal cord cystic lesion as the thirdstage larva of Gnathostoma, probably G. nipponicum or G. hispidum, based on the sectional morphologies.

One of the suprahyoid muscles is the digastric muscle which comprises anterior and posterior bellies joined by an intermediate tendon. Because of its close relationship with the submandibular gland, lymph nodes, and chief vessels of the neck, detailed knowledge about the morphometry of the digastric muscle is essential. The objective of the current cross-sectional evaluative study is to record morphometry along with the digastric muscle's origin, insertion, and variability. Forty human cadavers (25 males and 15 females) were dissected, and the head and neck regions were studied in detail. The attachment of the digastric muscle anterior belly to the digastric fossa of the mandible was noted, and the distal attachment of the posterior belly to the mastoid notch was traced. The length of the anterior belly from the digastric fossa to its intermediate tendon and the length of the posterior belly from the intermediate tendon to its mastoid attachment were measured. There is a fair correlation between the length of the neck and the length of the anterior and posterior belly. The study also identified two cases of bilateral accessory bellies of the anterior belly of the digastric. Normal morphometric data is provided by this study on details of the digastric muscle. It is significant from a clinical and surgical point of view as the muscle lies in proximity to the important structures of the neck.

The following study looked at the effects of Hyangsayukgunjatang and Hyangsayukgunjatang-ga-kyenegum, moryobun on gastric ulcers in rats. In the 1st experiment, ulcers were induced by method of shay's pylorus-ligated in rats. Subjects were administered 2 kinds of medicine, Hyangsayukgunjatang and Hyangsayukgunjatang-ga-kyenegum, moryobun, which were taken orally. The quantity of gastric juice secretion, total acidity of gastric juice, HCI secretion and serumgastrin content were measured and tissues of gastric mucosa epithelium were observed. 1. The quantity of gastric juice secretion in Hyangsayukgunjatang-treated and Hyangsayukgunjatang-ga-kyenegum, moryobun-treated groups showed significant decrease incomparision with the control group. 2. In relation to total acidity of gastric juice, only Hyangsayukgunjatang -treated groupshowed significant decrease in comparison with the control group. 3. HCI secretion of Hyangsayukgunjatang-treated and Hyangsayukgunjatang-ga-kyenegum, moryobun-treated groups showed significant decrease in comparision with the control group. 4. Content of serum gastrin, which were present in Hyangsayukgunjatang -treated and Hyangsayukgunjatang-ga-kyenegum, moryobun- treated groups showed significant decrease in comparision with the control group. 5. The degree of ulcer occurrence & parietal cell numbers and chief cell numbers of Hyangsayukgunjatang-treated and Hyangsayukgunjatang-ga-kyenegum, moryobun-treatedgroups, which were observed by macrographic & histologic method showed signicant decreasein comparison with the control group. Hyangsayukguniatang-treated group prooved to be increasingly effective. From above the experiment results it can be concluded that Hyangsayukgunjatang will be more clinical effective on curing gastric ulcers induced by method of Shay's pylorus-ligated rather than that of Hyangsayukgunjatang-ga-kyenegum, moryobun.

Three cases of hyperparathyroidism are presented from our experience at Presbyterian Medical Center in Chonju in the hope that this will alert us all to the variegated patterns of clinical presentation. In the first case the principal symptom was muscular weakness. In the second a bone cyst (which was part of the syndrome of osteitis fibrosa cystica); and in the third case rib cage tenderness, backache, and persistent epigastric pain. All three had adenomas, but in Case 2 the adenomas were multiple. All three responded to surgical resection and remain well.

Pleomorphic adenoma is the most common salivary benign tumor, constituting over 60% of parotid gland tumor, 25% of sublingual gland tumor and 50% of minor salivary gland tumor. It is somewhat more frequent in the fourth to sixth decades. The recurrent rate which enforces only a simple enucleation is very high $(20{\sim}45%)$. Histologically, it contains the epithelial cell, the myo-epithelial cell and mesenchymal ingredient, which is various aspect. We analyzed clinicopathologically and immunohistochemically the patients(34 cases) who are diagnosed with pleomorphic adenoma in Dept. of Oral & Maxillofacial Surgery, College of Dentisty, Dankook university since 1998. The results are as follow: 1. The incidence of the tumor was most frequent in age 30 to 50. The ratio of male to female was 1:1.43. 2. The most chief complain was a painless mass(94.1%) and the duration time was more than decade in 18 cases(52.9%). 3. Palate(soft & hard palate) was the most occurred site(64.7%). In major salivary glands, the parotid gland was the most frequent site(17.6%). 4. The tumor size was 2 to 3cm on the average. Most of tumors were with capsule(91.2%). 5. Surgical excision was a main treatment method(20 cases, 58.8%) and 14 cases were excised with a glandectomy, 1 case was treated with a partial maxillectomy. Only 1 case of all cases was recurred. 6. Histopathologically, 9 cases(26.5%) were cellular type, 11 cases(32.4%) were intermediate(classic) type and 14 cases(41.1%) were myxoid type. 7. Immunohistochemically, the specimen of all tumors reacted positively to cytokeratin and vimentin marker.

There appears to be significant problems remained in the treatment of tuberculous empyema with BPF in spite of several surgical methods: decortication, thoracoplasty, and pleuropneumonectomy. We presented one case of tuberculous empyema with BPF. The patient was 42-year-old male and his chief complaint was hemoptysis. In past history, he was treated with left closed thoracostomy and antituberculous medication for two months, 16 years ago. Chest X-ray, tomogram and C. T, revealed a huge mass with central necrosis in the lower 2/3 of left thoracic cavity and shifting of the mediastinal structure to the right. Needle aspiration cytology was undifferentiated large cell carcinoma. Left thoracotomy was made under the impression of lung cancer and pleuropneumonectomy was done. Operative findings; thick walled empyema sac filled with hematoma and BPF, the mediastinum was fixated due to fibrosis and calcification of the pleura and the mediastinum. Postoperative biopsy was consistent with tuberculosis. In the postoperative course, there was massive hemorrhage and so reoperation was done. But there was no active bleeding focuses in the thoracic cavity at the time of reoperation. Massive transfusion, coagulant therapy and intermittent clamping and declamping of the chest tube were carried out. Especially, serum calcium level was chronically decreased and so large amount of calcium gluconate was infused for the calcium level to be normal. Total transfused blood; whole blood was 33 pints, packed cell was 63 pints and fresh frozen plasma was 70 pints. At the postoperative[reop] 45th day, intrathoracic hemorrhage was stopped and the chest tube was removed. In conclusion, this suggest that uncontrollable bleeding after pleuropneumonectomy of the tuberculous empyema with BPF could be treated without reoperation in case of the mediastinal fixation due to fibrosis and calcification of the pleura and the mediastinum.
