Two cases of congenital hyperostosis at a pig farm were observed and examined pathologically in Landrace piglets. Twenty two piglets from 2 litters: 10 alive piglets in a litter and 2 stillborn and 10 alive piglets in another, were born with thickened forelimbs and some of them with thickened hindlimbs too. These piglets stowed symptoms of staggering and incoordination. Only one of these piglets could be reared normally and all the others died within 3 days of age. The thickened parts of their limbs were felt firm and not well pitted by finger pressing. An apparent ossification was identified on the central regions of the cross sections of the thickened limbs, and some pale, gray and ossiferous signs were found in the peripheral soft areas. On histopathological examination of the thickened limbs, it was found that the bone trabeculae were newly proliferated in a concentric form in central regions and in a radiated form in peripheral regions. The peripheral regions of the periosteum and perichondrium of new bone were proliferated with connective tissue and the edematous muscle bundles were atrophic and degenerative. Both the sows which produced piglets of congenital hyperostosis were mated with a different boar at next breeding and farrowed normal piglets. It was concluded that the swine congenital hyperostosis in the present cases was expressed by autosomal recessive gene of first mating boar.

Although primary surgical excision is the treatment of choice for the vast majority of patients with nasopharyngeal angiofibroma, radiation therapy is also employed as a primary tool or in the cases of tumor recurrence or massive intracranial extension. But, especially in young patients, postradiation sequelae such as osteomyelitis, atrophic rhinitis, thyroid or bone malignancy are of concern. Postirradiation osteosarcoma is a rare, but well-recognized complication of radiotherapy, which comprise roughly 2 to 5 percent of all osteogenic sarcoma. Recently we experienced a case of postirradiation osteosarcoma of the mandible who had treated by radiation therapy for the nasopharyngeal angiofibroma 30 years ago, presently he is ongoing chemotherapy and relatively being well.

According to the increase in use of implants in clinical dentistry, new kinds of complications happen. Complications that can happen during implant placement are bleeding, nerve injury, jaw fracture, fenestration of maxillary sinus or nasal cavity, dehiscence, fenestration, injury of adjacent tooth. And complications that can happen after implant operation are infection, bleeding, hematoma, chronic sinusitis, peri-implantitis. Problems that are confronted during implant placement happen by inadequate preoperative treatment plan, inadequate consideration about individual anatomic difference, inadequate operation process and lack of experience of clinician. It is important that clinicians consider possible complications in advance and make a comprehensive treatment plan. We report the patient who was happened ramus fracture during block bone harvesting from ramus of severely atrophic mandible, the patient who came to emergency ward due to postoperative swelling and bleeding and the patient whose implant was migrated to maxillary sinus with a review of literature.

Objectives: This study was to evaluate the effect of Palmijihwang-whan (PMJHW) aqueous extract in the regulation of hypothyroidism related reproductive organ damages in propylthiouracil (PTU)-induced rat model. Methods: PMJHW aqueous extract (yield=17.90%) were administered, once a day for 42 days from 2 weeks before start of PTU treatment as oral doses of 500, 250, and 125 mg/kg (body weight), and hypothyroidism was induced by daily subcutaneous treatment of PTU 10 mg/kg for 28 days. Results: PTU-induced hypothyroidism and related male reproductive organ damages-atrophic changes of testis, epididymis and prostate, were favorably and dose-dependently inhibited by treatment of PMJHW 500, 250, and 125 mg/kg. They also effectively regulated the PTU-induced abnormal antioxidant defense system changes in the testis. Although levothyroxine also favorably inhibited PTU-induced hypothyroidism, it deteriorated the hypothyroidism related male reproductive organ damages through testicular oxidative damages. The results suggest that oral administration of 125, 250, and 500 mg/kg of PMJHW has favorable effects on the hypothyroidism and related reproductive organ damages through augmentation of antioxidant defense system in the testis. Conclusions: This study suggest that PMJHW may be help to ameliorate the hypothyroidism and related organ damages in clinics.

Pasteurella multocida serogroup D strain, which produces P. multocida toxin (PMT), is a widespread and harmful pathogen of respiratory diseases such as pneumonia and progressive atrophic rhinitis (PAR) in swine. Vaccination has been considered the most desirable and effective approach for controlling the diseases caused by toxigenic P. multocida. To investigate the antigenicity and immunogenicity of partial fragments of recombinant PMT, recombinant proteins of the N-terminal (PMT-A), middle (PMT-B), C-terminal (PMT-C), and middle-C-terminal (PMT2.3) regions of PMT were successfully produced in an Escherichia coli expression system. The molecular masses of PMT-A, PMT-B, PMT-C, and PMT2.3 were ca. 53, 55, 35, and 84 kDa, respectively, purified by nickel-nitrilotriacetic acid (Ni-NTA) affinity column chromatography. All the recombinant proteins except for PMT-A showed immune responses to antisera obtained from a swine showing symptoms of PAR. Moreover, high titers of PMT-specific antibodies were raised from mice immunized with each of the recombinant proteins; however, the immunoreactivities of the antibodies to authentic PMT and heat-inactivated whole bacteria were different, respectively. In the protection study, the highest protection against homologous challenge was shown in the case of PMT2.3; relatively poor protections occurred for the other PMT fragments.

Background: The conventional transcervical resection for submandibular gland disease has some risks and an unsatisfactory cosmetic result. Recently, robot-assisted surgery has been developed as a plausible substitute for conventional surgery which provides an excellent cosmetic outcome. Case presentation: The authors performed robot-assisted sialadenectomy via modified facelift incision using the da Vinci Xi surgical system (Intuitive Surgical Inc., CA, USA) with two endowrist arms (monopolar curved scissors and Maryland bipolar forceps) successfully in a 44-year-old female patient who suffered from sialolith and severe atrophic submandibular gland. Conclusions: If similar studies are done in the future, this robot-assisted sialadenectomy may become established as an alternative to existing disadvantageous surgical methods.

Loss of tooth results in remodeling and resorption of surrounding alveolar bone which causes atrophic edentulous ridge and gradually decreasing gingival attachment. As a result, edentulous patients face difficulty in using dentures due to pain, decrease of support, decline of masticatory efficiency of complete denture. To improve this, overdenture with implant in the mandible and attachment are considered as a treatment of choice as a favorable treatment. In this case, a patient with edentulous ridge for long period is rehabilitated by complete denture in maxilla and implant overdenture using Locator$^{(R)}$ attachment in mandible.

In order to see whether the mamillary bodies participate in the control of female gonadotrophic function, 12 female rats in which the mamillary bodies were damaged by passing 0.3 ma direct cur-rent through stereotaxically implanted electrodes, 8 rats which received the same treatment except passage of current, and 9 normal rats were prepared. One month after the operation, all animals were sacrificed and their brain lesions checked histologically, their ovaries and uteri examined and weighed. The ovaries and uteri showed neither atrophic changes in any animal, nor significant differences in the weight among the 3 groups. Thus the results do not support the idea that the mamillary bo-dies are implicated in the control of female gonadotrophic function.

The present study was conducted to investigate the isolation frequency, biochemical prop erties and antimicrobial susceptibility of B. bronchiseptica isolated from slaughtered pigs during the period from March to December, 1992. In Kyeonggi province. A serological survey for antibody of B. bronchiseptica in 200 slaughtered pigs was carried out by agglutination and tetrazolium reduction methods. The results were summarized as follows ; 1. From 80 slaughtered pigs, 27(33.8%) case were isolated and all isolate strains were resistant to Penicillin, Streptomycin, Chloramphenicol, Tetracycline and Ampicllin, while the majority of them were susceptible to Gentamicin, Cloxacin, Colistin, Neomycin, and Kanamycin. 2. Incidence of B. bronchiseptica antibody in 200 slaughtered pigs were measured by agglutination and tetrazolium reduction methods. Agglutination method was shown 38 (19%) of 200 with a titer of below 1：20 and 20(10%) of 200 with a titer of above 1：640. Tetrazolium reduction method was observed 33(16.5%) of 200 with a titer of below 1 : 20 and 32(15%) of 200 with a titer of above 1：640. 3. LSD analysis indicated that the difference of the responses between agglutination test and tetrazolium reduction test was not significant.

Objectives: The purpose of this study is to review clinical studies and evaluate effectiveness of intravaginal administration of oriental medicine on vaginal atrophy in menopausal women. Methods: 'postmenopause', 'menopause', 'vaginal atrophy', 'atrophic vaginitis', 'vaginal cream', 'vaginal gel', 'pessary', 'suppository' were searched on 3 online databases (Pubmed, Cochrane Library, OASIS). The risk of bias was assessed by using Cochrane risk of bias (RoB) 2.0 tool. Results: 9 randominized controlled trials (RCTs) were selected among 489 articles. The types of intervention were intravaginal administration of oriental medicine. 6 studies showed that treatment group was better than placebo control group or both treatment group and western medicine control group improved similarly. 2 studies were not significant effective in some results and 1 study was not statistically significant. Conclusions: Intravaginal administration of oriental medicine can be an effective option in treating menopausal women with vaginal atrophy. but considering the small number and low quality of studies, further well-designed studies are needed to confirm the effectiveness of this treatment.
