In this report, laparoscopic ovariohysterectomy (LOHE) was performed on two, healthy, intact female dogs. Three ports, umbilical port for placing the laparoscope and the left and right paramedian instrument ports were placed into the abdominal cavity. First, in order to isolate the right ovary, the vascular pedicle was coagulated by activating the universal bipolar forceps. Then, the pedicle and suspensory ligament were transected by the bipolar electrocauterization scissors. In the same manner, the left ovary was isolated. The uterine body and the uterine arteries were coagulated bilaterally and transected just rostral to the cervix. The isolated ovaries and uterus were exteriorized through the left paramedian instrument port, which was extended by approximately 1 cm to allow for tissue removal. The skin and subcutaneous tissue were closed in a routine manner. Surgical times for LOHE in two dogs were 35, 40 min respectively. Total length of abdominal incision was shorter than 3 cm in two dogs. No clinical complications related to the LOHE were observed during 1.5 years after surgery. The LOHE is an alternative surgical technique that deserves further investigation.
Chylothorax is denned by extravasation of the milky fluid to pleural cavity from the thoracic duct or it's main branches due to operative trauma, congenital lesions, diagnostic procedures, tumor, etc. Another rare cause is diffuse pulmonary Iymphangiomatosis which is uncommon and not well charact rized. We experienced a case of the bilateral chylothorax caused by the diffuse pulmonary Iymphangiomatosis. The patient was at years old girl with symptoms of coughing and febrile sensation, and the chest radiographs showed bilateral pleural effusion and interstitial infiltrates. The laboratory data of the pleural effusion was identified as chile. Uncontrollable with closed tube thoracostomy, division of tHe thoracic duct and biopsy were decided. Biopsy showed anastomosing endothelial lined spaces along the pulmonary Iymphatic routes especially in pleural and interlobar septum, and smooth muscle at the proliferative interstitium of the Iymphatic duct was observed. Postoperatively, chylothorax was controlled with several trial of chemical pleurodesis. Af'leer discharge from the hospital, she was well for ten months follow up.

The mesothelium is an essential lining for maintaining the normal homeostasis of the closed body cavity and a central component of pathophysiologic processes. The mesothelium has been known as the end target for asbestos which induces asbestos-related lung diseases. Malignant mesothelioma (MM) is a rare and fatal neoplasm predominantly due to asbestos exposure. Adaptation of an advanced and reliable technology is necessary for early detection of MM because it is difficult to diagnose this disease in its early stages. Optical coherence tomography (OCT) provides cross-sectional images of micro-tissue structures with a resolution of $2-10{\mu}m$ that can image the mesothelium with a thickness of ${\sim}100{\mu}m$ and, therefore, enable investigation of early development of MM. The mesothelium is typically located at the pleura and tunica vaginalis of the scrotum. In this study, we developed animal window models in the above two anatomical sites to visualize mesothelial layers within the mesothelium. OCT images at the two locations were also acquired.
Noonan syndrome is characterized by a Turner-like phenotype and a normal karyotype associated with congenital abnormalities, such as short stature, variable mental retardation, hypertelorism, webbed neck, low posterior hair line, skeletal malformation and congenital cardiovascular defect. Two third of Noonan syndrome have cardiac anormalies, half with pulmonary stenosis. We have experienced two cases of pulmonary stenosis associated with other cardiac anomalies in Noonan syndrome. The first 31-year-old male patient had characteristic appearance of Noonan syndrome with severe infundibular pulmonic stenosis and patent foramen ovate. The second 28-year-old male patient had valvular and subvalvular Pulmonary stenosis with typical Noonan\`s face and stature. Pulmonary valvotomy and hypertrophied muscle bundles in the right ventricular cavity were resected in both cases. Patent foramen ovate was closed directly in the first case. Postoperative follow-up examinations revealed no symptoms and successful outcome.

This study was performed to inquire into recognition of cold and heat application. The subjects in the study were 429 adults who were collected by disproportional quota sampling according to age, sex. The instrument was 36 questions that constitured closed questions and semiopened questions that encluded general characteristics, recognition of cold and heat applications. and what will you do when requested cold and heat applications on abdomial and perineal areas. Data were collected from september 25 to October 25, 1998. Data was analysed by SPSS/win, into frequency, Pearson correlation, t-test, ANOVA. The results were following. 1) The subjects consisted of male and female who was from teenage to fifty year old above. According to general characteristics, who endureed moderate cold-heat application, had constitutional fever, good sweat, and taked a cold bath accationally. And the woman think that their body were more cold than man. and the number of cold bath was less than man. Woman felt more harder than man that endured exposing cold. According to the recognitions of cold-heat applications, the 61.9% of the subjects think that cold application is more positive, and the 61.7% of the subjects think that heat application is more positive. 2) The subjects think that oral cavity, abdomen, back, extremes must be warm. 3) The percents of cold or heat application at abdomen were 77.4%, 86.5% respectely and the percents of cold or heat application at perineum were 56.9%. 93.6% respectely. With the above results. we know that the subjects have the fixed perceptions that each body part has to maintain its temperature. especially, they think that postpartum care is correlated with cold-heat application. So when we intervent nursing care, we also must regard their recognitions of cold and heat applications. and we need to educate and explain correctly about cold-heat application.
Cleft lip and palate is one of the congenital anomalies which need comprehensive and multidisciplinary treatment plan because 1) oral cavity is an important organ with masticatory function as a start of digestive tract, 2) anatomic symmetry and balance is esthetically important in midfacial area, and 3) it is also important to prevent psycho-social problems by adequate restoration of normal facial appearance. There are many different protocols in the treatment of cleft lip and palate, but our department has adopted and modified the $Z{\"{u}}rich$ protocol, as published in the Journal of Korean Cleft Lip and Palate Association in 1998. The first challenge is feeding. Type of feeding aid ranges from simple obturators to active orthopedic appliances. In our department we use passive-type plate made up of soft and hard acrylic resin which permits normal maxillary growth. We use Millard's method to restore normal appearance and function of unilateral complete cleft lip. In consideration of both maxillary growth and phonetic problems, we first close soft palate at 18 months of age and delay the hard palate palatoplasty until 4 to 5 years of age. When soft palate is closed, posterior third of the hard palate is intentionally not denuded to allow normal maxillary growth. In hard palate palatoplasty the mucoperiosteum of affected site is not mobilized to permit residual growth of the maxilla. We have treated a patient with unilateral complete cleft lip and palate by Ajou protocol, which is a kind of modified $Z{\"{u}}rich$ protocol. It is as follows: Infantile orthopedics with passive-type plate such as Hotz plate, cheiloplasty with Millard's rotation-advancement flap, and two stage palatoplasty. It is followed by orthodontic treatment and secondary osteoplasty to augment cleft alveolus, orthognathic surgery, and finally rehabilitation with conventional prosthodontic treatment or implant installation. The result was good up to now, but we are later to investigate the final result with longitudinal follow-up study according to master plan by Ajou protocol.
The purpose of this study was to investigate the effect of phosphoric acid concentration on the movement of 2-hydroxyethylmethacrylate(HEMA) from bonding resin - resin composite combination through dentin in vitro. Freshly extracted human third molar teeth were divided into four groups each of 10 teeth. A closed chamber with 1 ml distilled water was attached to the CEJ of each tooth. An occlusal cavity of 4mm diameter & remaining dentin thickness of 1.0-1.5mm was prepared in each tooth. Dentin was treated with 10% phosphoric acid gel for 15 seconds. 32% phosphoric acid gel for 15 seconds, or with 35% phosphoric acid gel for 15 seconds. A control group not treated with acid gel was also prepared. The cavities were rinsed, dried and then treated with the HEMA-containing All-Bond 2 primer & bonding resin which was light-cured for 10 seconds. The cavities were then restored with Z100 composite resin(shade:A3.5:3M Dent. Prod. USA) & light cured for 30 seconds. Water samples were retrieved from the chambers over a time course (4.32, 14.4, 43.2, 144 & 432 minutes ; 1, 3 & 10 days) and analyzed by high performance liquid chromatography. The results were as follows. 1. HEMA was detected in the pulp chambers of all teeth from 4.32 minutes after resin placement The highest rate of release was in the first sample period (0-4.32 min) & rate of release declined exponentially thereafter. 2. No significant differences were found for mean release rate for HEMA over a time course among the four groups (p>0.05). 3. The diffusion rate was significantly (p<0.05) less for 10% phosphoric acid gel than 32% phosphoric acid gel at the second sample period(4.32-14.4 min). 4. No significant differences were found for cumulative HEMA diffusion among the four groups at 10 days(p>0.05) and mean total(cumulative) release at 10 days for all groups was in the 9 - 16 nmol range. 5. The cumulative release was significantly (p<0.05) less for 10% phosphoric acid gel than 32% phophoric acid gel at the third(14.4-43.2 min) & fourth(43.2-144 min) sample period.
ATP drives the conformational change of the group II chaperonin from the open lid substrate-binding conformation to the closed lid conformation to encapsulate an unfolded protein in the central cavity. It is thought that the folding activity of group II chaperonin is strongly correlated with the ATP-dependent conformational change ability. In order to confirm the dependence of the reaction temperature and ATP concentration of PhCpn, the ATPase activities were measured under different reaction temperatures and ATP concentrations. The maximal ATPase activity of PhCpn was observed at 80℃ and 3 mM ATP concentration. As a result of ATPase activity according to the type of salt ions, the highest activity was observed at 300 mM LiCl among the univalent cations and 5 mM MgCl2 among the divalent cations, respectively. The values of Km and Vmax for ATP substrate were estimated as 2.17 mM and 833.3 μM/min, respectively. This results provide the enzymatic information of PhCpn when the prolonged and high activities of pharmaceutical and industrial proteins (or enzymes), by using chaperonin molecules, are required.

This study was performed to examine the presence of dysphagia and analyze characteristics of the symptoms in cerebrovascular accident(CVA) patients without awareness of dysphagia. A questionnaire for this study was given to CVA patients who had visited P rehabilitation medical center in Busan. Eleven patients (4 males and 7 females) who answered no awareness of dysphasia were given to VFSS, functional dysphasia scale, and NCSE. Descriptive statistics and Pearson correlation analysis were performed by SPSS 12.0. All of subjects without awareness of dysphasia showed characteristics of dysphasia symptoms. Prominent dysfunctions were problems in oral phase and delay of swallowing reflex in pharyngeal phase. For the aspect of cognition, they showed lower score in construction, memory, and similarity than other NCSE items. There was highly significant correlation between orientation, judgment and delay of swallowing reflex. Verbal comprehension and residual materials in oral cavity showed closed correlation. CVA patients without awareness had dysphagia with high probability. The early evaluation of dysphagia should be performed in CVA patients in order to prevent complications due to CVA, so it is necessary to increase the effectiveness of rehabilitation therapy.
Purpose: Hyoid bone is a U-shaped bone in the anterior of the neck. Hyoid bone fractures are exceedingly rare and represent only 0.002% of all fractures because of its protective position relative to the mandible and its suspension by elastic musculature. We report a patient who presented hyoid bone fracture associated with hypoglossal nerve palsy. We also discuss the possible complication and treatment. Methods: A 69-year-old man was transferred from another institution because of persistent purulent discharge from the left chin. He had a history of trauma in which a knuckle crane grabbed his face and neck in the construction site. A CT scan at the time of the accident demonstrated a comminuted fracture of the right side of the mandible and hyoid bone fracture at the junction between body and right greater cornua. The displaced fracture of hyoid bone and fullness in the pre-epiglottic space were noted, probably indicating some edema. The patient was transferred into ICU after treatment of emergency tracheostomy because the patient showed respiratory distress rapidly. When the patient was hospitalized in our emergency room, he complained of dysphagia and pain when swallowing. On examination of oral cavity, the presence of muscle wasting with fasciculation of the tongue was noted and the tongue deviates to the left side on protruding from the mouth. Pharyngolarygoscopy was performed to make sure that there was no evidence of progressive swelling and pharyngeal laceration. Results: The patient underwent surgical removal of dead and infected tissue from the wound and reconstruction of mandibular bony defect by iliac bone grafting. Hyoid bone fracture was managed conservatively with oral analgesics, soft diet and restricted movement. Hypoglossal nerve palsy was resolved within 7 weeks after trauma without complications. Conclusion: Closed hyoid bone fracture is usually uncomplicated and thus it can be treated conservatively. Surgical intervention for hyoid bone fracture is recommended for patient with airway compromise, pharyngeal perforation and painful symptoms which show no response to conservative care. Furthermore, since respiratory distress syndrome may develop quickly, close observation is required. Besides, hypoglossal nerve palsy is a rarely recognized complication of hyoid bone fracture.
