Gross and histological findings were obtained on cysts formed in the reproductive organs, particularly in the mesosalpinx, mesovarium, and fimbria, of 144 gilts and 37 sows. Of the 181 gilts and sows, 63 (34.8%) were found to have cysts which totaled 89. The number of cysts totaled 38 for the gilts and 51 for the sows, with relative frequencies of 18.1% and 48.6%, respectively. The total number of cysts and the incidence were greater in the sows than in the gilts. With regard to the location of cysts, the highest incidence was found in the mesosalpinx (59.6%). The incidence of cysts in the mesovarium and fimbria was relatively low, with 16.9% and 23.6%, respectively. Most cysts were spherical or oval in shape, and below 5.9mm in diameter. A pedunculated cyst was also seen. The bilateral, incidence of the cysts was lower than unilateral, although the incidence was approxmately the same between the gilts and the sows. With regard to the sexual cycle, the high incidence of cysts was found in the follicular phase than in the luteal phase. The cysts putting pressure upon the oviduct were classified into 3 types according to the shape of epithelium and lamina propria. In type I the epithelium had ciliated cells and the lamina propria formed folds. I type 2 ciliated cells existed, but no folds were formed. In type 3, neither ciliated cells nor folds were seen, the histological change, including partial atrophy and lack of folds in the tubal mucosa were seen.

From September 1993 to August 1997, we treated ovarian disorders in 1,782 repeat breeder cows after diagnosis by ultrasound on 35 farms in Kyeong-ki do. The rates of ovarian appearance were 59.8% of CL group, 16.7% of ovarian atrophy or hypofunction, 15.4% of luteal cyst, 4.3% of follicular cyst and 3.7% of follicle group in diagnosis with rectal palpation and ultrasound. The results of treatment for ovarian disorders were 1,316 cows(73.8%) in estrus, 348 cows(19.5%) in non-detected and 118 cows(6.6%) in unidentified. The rates of PGF$_2$$\alpha$, GnRH and mineral vitamin complex treatment to estrus were 79.6, 69.2 and 50.3%. Two groups were treated with 5 ml PGF$_2$$\alpha$ intramuscular injection(I.M.) and 1.5 ml PGF$_2$$\alpha$ intraovarian injection(I.O.), and the results of 1.5ml PGF$_2$$\alpha$ I.0. were significantly higher than that of 5ml PGF$_2$$\alpha$ I.M. in inductiom estrus(p<0.05). The pregnant rates were 29.8% in total repeat breeder cows with ovarian disorders following diagnosis and treatment. In summary, rectal palpation and ultrasonography were proven to be useful tools of diagnosis and treatment in ovarian disorders, and it was also suggested that the response to treatment with PGF$_2$$\alpha$ I.0. was better than PGF$_2$$\alpha$ I.M.

Reproductive disorders in cows cause economic loss in livestock farms. Reproductive diseases, such as follicular cyst, luteal cyst, endometritis, pyometra, and repeat breeding cause infertility. Among these diseases, endometritis and pyometra are uterine infections that are leading causes of infertility. This study was performed to investigate the causative agents of uterine diseases using bacterial culture. Bacteria were obtained from the reproductive organs (vagina, uterine cervix, and uterine horn) of dairy cow diagnosed with endometritis or pyometra, and cultured on blood agar. The colonies obtained from cultivation for 24 hours were passaged. To identify the bacteria, the colonies grown in passaged culture Gram stained and applied to an automatic biochemical microbial identification system. Escherichia coli were commonly detected in vagina, uterine cervix, and uterine horn of dairy cows diagnosed to pyometra. The cows having endometritis showed not only Escherichia coli but also Pantoea spp. and Klebsiella spp. strains. Dairy cows that were infected with Escherichia coli in uterus caused mastitis or digestive disease. These results suggest that sanitary feeding and management beforehand are needed to prevent bacterial infections.

The author has clinically and radiologically investigated 57 cases of odontogenic keratocyst in 47 patients consisted of 26 males and 21 females aged from.2 to 63 years, who were pathologically diagnosed as odontogenic keratocyst at infirmaries of dental colleges, Yonsei University and Seoul national university during 1965-1986. The results were as follows: 1. The peak incidence of the disease was on their teenagers (29.8%). The ratio of Male/Female was 1.23:1 and incidence rate of males showed higher than their counterpart. 2. The most frequent complaints were swelling in (65.9%) followed by pus discharge, unknown mass, pain, residual root. 3. The most common site was mandibular third molar and mandibular ramus region (15.8%) followed by mandibular body and ramus, mandibular third molar, mandibular anterior teeth. Incidence of this disease in mandible was higher than in maxilla. 4. The lesions not associated with adjacent teeth were (14.0%) and in the lesions associated with adjacent teeth (35.1%) showed root resorption, (50.9%) were without root resorption, (35.1%) showed tooth migration and (50.9%) were without tooth migration. 5. The border types of the lesions were scalloped type in (52.6%), smooth type in (47.4%) and morphological type were unilocular in (50.9%), multilocular in (49.1%). 6. The radiologic cyst type of the lesions were follicular type (42.1%) followed by primordial, unclassified odontogenic, residual, lateral periodontal, median mandibular, globulomaxillary type.

One hundred forty cows that have claw disorder have been used to study the association between lameness and reproductive disorders. Weak estrus owing to ovarian hypoplasia (41.4%) followed by follicular cyst (39.3%) was more frequent than any other disorders. Two hundred ninety-four cows have been used to study the association between lameness and calving to first service and calving to conception intervals depending on lactations, claw disease and floor conditions. And a comparison of number of services per conception between cows with lameness and cows free from lameness was carried out. The calving to first service intervals were significantly increased from average 78 to 102.5 days and calving to conception intervals were significantly increased from 109.6 to 150.6 days in cows with lameness. The calving to first service and calving to conception intervals were not significant different between lactations in cows with lameness. In comparison of calving to first service and calving to conception intervals in cows with lameness depending on claw disease and floor conditions, there was no significant difference. The average number of services per conception was increased from 1.73 to 2.57 in cows with lameness. Service numbers were more frequent during second lactation (3.0 services) but there was no significant difference between lactations in cows with lameness. Therefore, it is likely that the management of lameness is important factor on proper health control of cows and the cows with lameness show decreased fertility.

Ovaries of 21 bitches presented with gynecopathies were surgically removed and histologically examined. Standard histological, as well as immunohistochemical, classification of 193 cystic structures resulted in the classification of 72 cysts of subsurface epithelial structures (SES), 61 follicular cysts (FCs), 38 cystic rete ovarii (CRO), 13 lutein cysts (LCs), and 9 non-classifiable cysts (NCCs). In addition to the histological classification, results were interpreted according to subject medical history, clinical examination outcome, and macroscopic observations during ovariohysterectomy. Dogs with ovarian cysts (OCs) and associated reproductive perturbations were mostly nulliparous, of large breed, and had an average of $9.5{\pm}3$ years. Prolonged or shortened inter-estrus intervals of past heats, however, seemed to be relatively low-risk factors for the development of OCs in dogs. Furthermore, we provide histological observations of a rarely seen canine LC including a degenerated oocyte in the central cavity.

Background and Objective：A post-operative hypertrophic scar of the anterior neck is the leading complaint of the patients who underwent conventional thyroid surgery. In order to minimize the post-operative scar of the anterior neck, we performed thyroidectomy via axillary approach using operating microscope and a specialized retractor to determine technical feasibility. Patients and Methods：From January 2005 to December 2006, we performed thyroidectomy via axillary approach under operating microscope(f=400mm, ${\times}2.5$；OPMI $pico^{(R)}$；Zeiss, Germany) for benign unilateral nodule in 25 cases(all female, average age 34.5yrs). Under general anesthesia less than 7cm of skin incision was made in the axilla of ipsilateral side. A subcutaneous tunnel went over the pectoralis major muscle and the clavicle, and then through the sternocleidomastoid muscle and sternothyroid muscle was excised. The area around the thyroid was sufficiently dissected, and then a retractor designed for exposure via axillary approach was placed within the tunnel and under operating microscope thyroidectomy was performed. Results：There were 17 cases of thyroid nodulectomy and 8 cases of subtotal lobectomy. The mean average operative time was 102.64minutes. Postoperative complications included one case of postoperative bleeding, one case of temporary vocal cord paralysis, two cases of delayed wound healing, two cases of paresthesia of shoulder and arm, and two cases of hypertrophic scar of the axilla. Postoperative histopathology includes 17 cases of adenomatous hyperplasia, six cases of cyst, and two cases of follicular adenoma. For all cases hospitalization period was two days. Conclusion：Thyroidectomy via axillary approach under operating microscope has a good cosmetic advantage without a post-operative scar of the anterior neck. The procedure is simple due to direct vision using operating microscope, easy to identify important structures by magnifying them, and therefore surgical time can be reduced.

We analyzed the results of ethanol sclerotherapy in 47 patients with cystic thyroid lesion. Cytologic study showed all of the lesions to be benign. The patients were followed clinically and ultrasonically I month and 3 or more months after ethanol sclerotherapy. If the cystic lesions recurred, repeated treatment was offered. In 4 patients with pure cystic lesion, all of the patents had almost total resolution of the cystic lesions. In 43 patients with mixed cystic lesion, 16(37.2%) patients had almost total resolution of the cystic lesions, 10(23.3%) patients showed a decrease' in the cystic lesion of <50%, but 11(25.6%) patients it did not change in size. Overall, in 30(63.8%) patients the cystic lesion decreased in size. Eleven patients who were not effective by sclerotherapy or follicular proliferation by cytology were converted to surgery. Although no severe complication were observed, there were complication of severe pain in I patient and a drunken feeling in I patient. If the malignancy must be excluded by repeated cytologic examination of aspirated fluid, we consider instillation of ethanol into the cystic lesions of the thyroid to be a simple, safe, economical and effective treatment.
