1. The weights of ovary and uternus in the all treated groups were lighter than those in control group showing significantly differences from 4 weeks after treatment. The significant was not recognized between PTU and Thx. groups, and Thyro. and control groups. 2. In the histological changes of ovary, follicles were disa, pp.ared and alignment of membrana granulosa disnitergration in cell change were serious in Thx. and PTU groups and slight in Thyro. group. 3. In the histological changes of uterus, endometrial epithelium and lamina propria were atrophied from 3 weeks after treatment in Thx. group, from 4 weeks in PTU groups and from 5 weeks in Thyro. group. Muscular layers were atrophied with time elapse in the all treated groups. 4. The changes of the concentrations of serum progesterone at all observation times in Thx. and PTU groups were significantly decreased in comparison with those in control group. While those in Thyro. group were significantly increased in comparison with those in control group. 5. The concentration of serum estradiol-17$\beta$ at all observation times in all experimental groups were below 27.2pg/ml. Therefore, we did not detect any changes of the concentrations.

Three cats with 2 weeks to 1 month history of drooling, halitosis, difficulty eating and pain on opening the mouth were presented to local animal hospitals. On physical examination, the gingiva was swollen, bright red and very painful with bilaterally symmetric pattern. Surgically excised abnormal gingival biopsy samples were requested for diagnosis. Histopathologically, gingival epithelium showed severe hyperplasia and ballooning degeneration. Moderate to severe infiltration of lymphocytes and plasma cells were presented in lamina propria. Immunohistochemically, inflammatory cells of the samples demonstrated major positive reactions for T lymphocytes. But some plasma cells also presented. According to polymerase chain reaction, tissues samples were negative for four kinds of feline viral pathogens. Based on the clinical, gross, histopathologic findings, these three cases were diagnosed as lymphoplasmacytic gingivitis in cats. In our best knowledge, this is the first case report in Korea.

This study was undertaken to compare and investigate the wound healing process following Nd:YAG laser wounds and scalpel incisions of the rat tongue dorsal mucosa. Laser wounds were made parallel on the right side of tongue dorsum and scalpel incisions were made on the left side with 5mm length, respectively Visual inspection and immunohistochemistry with CD44 antibody after immediately, 6 hours, 1 day, 2, 4, 7, 11, 21 days after surgery were carried out. The results were as follows : 1. There was macroscopically no treat difference between laser wounds and scalpel incisions. 2. Laser wounds appeared as dry, bloodless and irregular grooves with carbonization and whitening of superficial tissues compared to sharp, straight and bleeding incisions using scalpel. 3. In the epithelium of rat tongue mucosa, CD44 expression in healing laser wounds and scalpel incisions were similar. 4. In the lamina propria and muscle layer, CD44 expression in healing laser wounds gradually increased earlier and decreased faster than scalpel incisions. Conclusively, it is suggested that pulsed Nd:YAG laser has more beneficial effect on the healing of wounded oral mucosa than scalpel in knew of CD44 expression.

We report our experience of a concurrent robot assisted distal gastrectomy and partial nephrectomy for synchronous early gastric cancer and renal cell carcinoma. A 55-year-old female patient was diagnosed with early gastric cancer on screening endoscopy. Abdominal computed tomography showed an incidental right renal cell carcinoma. Robot assisted distal gastrectomy was performed, followed by partial nephrectomy. The final pathological examination showed signet ring cell carcinoma within the lamina propria and renal cell carcinoma with negative resection margins. The patient showed no evidence of recurrence at 6-months. A robot-assisted combined operation could be a treatment option for early stages of synchronous malignancies.

The effects of folic acid on the oral mucosa of albino rats were histochemically studied in the twenty four male rats, weighing abut 100gm. Seven groups of 3 each were injected with 0.2ml folic acid (folic acid 0.5mg. was dissolved in physiological saline 0.2ml) subcutaneously, during 1,2,3,5,7,10 and 14 days respectively. Oral mucosa of rats sere removed from upper molar region and fixed in 10% formalin, cold absolute alcohol, Carnoy's solution and acetone. The serial sections were histochemically stained by McManu's PAS reaction, Mowry's metachromasia, alloxan-Schiff reaction, and azo dye method for alkaline phosphatase. The comparative staining method was hematoxylin-eosin stain. The results were as follows: 1) Alkaline phosphatase reaction of stratum spinosum and stratum granulosum tended to increase after 7 and 10 days of folic acid administration. 2) PAS reactions of basement membrane and lamina propria increased after folic acid administration. 3) Metachromasia of stratum spinosum and stratum granulosum were slightly increased after 3,5 and 7days of folic acid administration and returned to the level of Control after 10 days. 4) In the oral mucosa, alloxan-Schiff reaction increased after 7 days of folic acid administration.

This study was conducted for the histological observation of the infundibulum of the oviduct of the laying Korean native pheasants. The results are as follows : 1. The infundibular wall is composed of the epithelium, lamina propria, muscle layer(inner circular and outer longitudinal muscle), and serosa. The funnel lip is divided into the inner, and outer lip of the epithelium and muscle layer. 2. The epithelium of the funnel lip and most region of the cranial part of the funnel are composed of ciliated columnar cells. In the surface and lateral part of the folds, ciliated cells and non-ciliated secretory cells tend to alternate in the epithelium of the caudal funnel and the necks, but are also found in groups of the simple cuboidal epithelium at the bases of the grooves between the ridges and tubular glands found in the subepithelium. 3. The secretory material of the non-ciliated secretory cills contains PAS-positive and alcian blue-positive granules, and these materials show purple colour in the basic fuchsin-methylene blue stain. 4. The cells of the glandular groove and tubular gland of the neck portion of the oviduct mostly show weak PAS-positive, and alcian blue stain negative reaction. The tubular gland cells of the infndibulum contain pink of purple colour granules, and without reaction in the anterior neck portion of the infundibulum in basic fuchsin and methylene blue stain.

The term "phonosurgery," coined in the early 1960s, refers to surgical procedures that maintain, restore, or enhance the human voice. Phonosurgery includes phonomicrosurgery (endoscopic microsurgery of the vocal folds), laryngoplastic phonosurgery (open-neck surgery that restructures the cartilaginous framework of the larynx and the soft tissues), laryngeal injection (injection of medications as well as synthetic and organic biologic substances), and reinnervation of the larynx. Phonomicrosurgery is a means of maximally preserving the layered microstructure of the vocal fold, that is, the epithelium and lamina propria. The purpose of the surgery is usually to improve the vibratory characteristics of the layered microstructure of the vocal folds. Phonomicrosurgery has developed from convergence of microlaryngoscopic surgical technique theory and the mucosal wave theory of laryngeal sound production. Improvements in technology (i.e., laryngoscopes, handled instruments, and lasers), which in part arise from developments in more frequently performed minimally invasive surgical procedures, will probably facilitate the next generation of procedural innovations. The best methods of optimizing phonosurgical outcomes include making an accurate diagnosis, completing a comprehensive voice evaluation, providing sufficient preoperative therapy, carefully selecting patients to undergo phonomicrosurgical procedures, and requiring sufficient postoperative rest and therapy. Phonomicrosurgery will continue to evolve as a result of the interdependent collaboration of surgeons with voice scientists, speech pathologist, and other voice professionals.

A thirty-five week old elk was referred for Chronic Wasting Disease (CWD) confirmation from Chungnam province in Korea. Necropsy revealed much bloody contents in the lumen of small and large intestines, and reddening of its mucosa. Microscopically, few coccidia showing various developmental stages were infiltrated in lamina propria of small intestine with granulomatous inflammation and congestion. They were identified as Eimeria spp. according to their location and morphological characteristics. Because fecal examination and oocyst culture were not available, the species of the Eimeria could not be confirmed. There were no detection of pathogenic bacteria such as clostridia and virus in intestinal contents. CWD was shown to be negative in immunohistochemistry test. In conclusion, it was the first Eimeria case detected in small intestine of Korean domestic elk as far as we know although Eimeria spp. were not the main cause of death.

The present observations were focussed mainly on the macroscopic and histopathological observation to polyps encountered on the stomach of 4-month-old pig, small intestine of 3-month-old pig and cecum of 9-month-old dog. The results were summarized as follows; 1. The polyps were gray or pink hemispherical shapes attached by the broad base to the gastrointestinal walls and were 3 to 8 mm in diameter and diffuse appearance. The surfaces of polyps were flat or indented and were ulcerated in some large polyps. 2. In histopathological findings, the polyps were nodules composed of lymphoid follicles, which were characterized by the differentiation and proliferation of the lymphoid cells in the lamina propria or submucosa of the gastrointestinal tract. The lymphoid nodules have the thin septa and thick capsules of the connective tissues, also comprised more numerous and larger sinus-like-blood vessels and more diffuse lymphoid cells in the peripheral zones than those in the central zones of nodules. In addition, the external surface of the polyps bulged toward the intestinal lumen were covered with the abnormal epithelium, or the degenerative and necrotic lymphocyte aggregates. 3. These polyps were considered as lymphoid polyps caused by the hyperplasia of the lymhoid follicles.
