Fibronectin, a glycoprotein, is present in plasma and extracellular matrix and is responsible for cellular adhesion. Fibronectin was purified from autologous plasma of two persistent corneal epithelial defect patients by affinity chromatogaphy and administered topically 500 micro ml, 2 dropsper time, five times a day for 3 weeks. Reepithelization began three to seven days after initiation of treatment with autologous purified fibronectin eyedrops, and epithelial defects healed nearly completely and subjective symptoms were relieved. No side effects were observed. Over a follow-up period of 4 to 23 wks, no recurrences were noted.

The Tear Film Break-Up Time(BUT) in the diagnosis of the dry eye syndrome was widely used, but its results were variable according to the methods of measuring BUTs. Especially, the method of Fluorescein administration and concentration had a great influence on BUT. The purpose of this study was to standardize the method used in measurement of BUT, particularly fluorescein solution concentration. We measured BUT in seven groups of different fluorescein solution concentration and total subjects were 464 persons. The results were as follows; 1. The mean BUT was 14.24 +/- 2.04 seconds in 0.12% Fluorescein solution, 11.73 +/- 2.11 seconds in 0.25% solution, 11.34 +/- 3.00 seconds in 0.5% solution, 10.3 +/- 3.50 seconds in 1% solution, 9.59 +/- 2.74 seconds in 2% solution, 7.56 +/- 1.84 seconds in 5% solution and 5.55 +/- 1.20 seconds in 8% solution. 2. The more Fluorescein concentration was, the shorter BUT became and there were statistically significant decrease in 0.25%, 0.5% and 2% Fluorescein solution.

The great chain of sympathetic ganglia which extends from the base of the skull to the pelvis, including the suprarenal medulla, accounts for the origin of the ganglioneuroma which compound with the matured ganglion cells and neural elements. The ganglioneuroma is non-functioning tumor, but occasionally this tumor accompanies with hypertension and diarrhea and increased excretion of vanilmandelic acid in urine. Recently we experienced a housewife with the bilateral ganglioma which developed at both suprarenal medulla and after successful removal of the tumors hypertension was controlled.

Gastric tuberculosis is a rare disease. It usually occurs secondarily to another lesions and mainly in the lungs. Only a few cases of primary gastric tuberculosis have been reported in the literature. Most commonly, gastric tuberculosis lesion locates in the lesser curvature side of the antrum. Therefore the clinical picture is similar to the peptic ulcer. A 24-year-old women visited to the Inha university hospital complaining of vomiting and epigastric discomfort. Gastrofiberscopy showed multiple polypoid mass around the pylorus with stenotic pyloric channel. Subtotal gastrectomy was performed and histologic examination revealed chronic granulomatous inflammation with caseation necrosis. That is compatible with tuberculosis. The patient was taken antituberculosis medication without complication. So we report the case of pyloric obstruction due to gastric tuberculosis with review of the literature.

Most elderly women experience a decrease in their bone density due to a deficiency of calcium intake, ovariectomy, or menopause. This study evaluated the usability of the microscrew as a skeletal anchorage system in these orthodontic treatment cases, using rats as a research group. The 4 month old sprague-dawley species rats were divided into two groups, the OS (Ovariectomy Screw), and the SS (Sham operation Screw) group. In both the OS and SS groups, microscrews were implanted into the palatal bone between the upper molar teeth and two upper incisors were retracted using NiTi coil spring with 75 g of force. After 3 days, the again after 7 days, 7 rats in each group were sacrificed. Three days before they were sacrificed, Alizarin red S was intraperitoneally injected, and their maxillary bone, tibia and blood from their hearts were taken. The components of the extracted blood were biochemically analyzed and non-decalcified grinding resin sections for maxillary bone and tibia were made. The sections were examined with a polarization microscope, and fluorescent microscope. Smaller concentrations of Ca and P, the inorganic substances closely related to bone density, were found in the extracted blood of the OS group. Both OS and SS groups showed a possibility of bone remodeling with a high concentration of ALP after 7 days. An increase in bone density on the tension and compression sides of the microscrew and the tension side of the tooth for both OS and SS groups was confirmed with a polarization microscope. However, the bone density of the pressure side of the tooth and apical side was decreased. More deposits of Alizarin red S in the bone after 7 days rather than 3 days seen with a fluorescent microscope suggested the existence of new bone formation.

A nationwide survey on radiation safety management in Korean animal hospitals was conducted. By 2013, 53 radiation generators were registered as veterinary medical devices (41 X-ray generators and 12 computed tomography scanners). Additionally there were six approved laboratories for radiation equipment and protection facility, and five approved laboratories for radiation exposure of employees, respectively. By March 2013, 2,030 out of 3,829 animal hospitals operated radiation-generating devices. Among these devices, 389 (19.2%) out of 2,030 were not labeled with the model name and 746 (36.7%) were not labeled with production dates. Thus, most veterinary X-ray generators were outdated (42.6%) and needed replacements. When periodic inspections of 2,018 animal hospitals were performed after revision of the Veterinarians Act in 2011, the hospitals were found to be equipped with appropriate radiation generators and protection facilities. Among 2,545 employees exposed to radiation at the hospitals, 93.9% were veterinarians, 4.3% were animal nurse technicians, and 18% held other positions. Among 169 employees supervised by administrators, none of those had a weekly maximum operating load that exceeded 10 mA.min. This study suggests that the radiation safety management system of animal hospitals was general good.

In this study, the Korean veterinary medical devices management system was evaluated relative to systems in the USA, EU, and Japan. Veterinary medical devices are regulated in Korea based on the Medical Appliance Act of 1997. This was initially supervised by the Ministry of Agriculture, Food and Rural Affairs and Korea Animal Health Products Association, and subsequently by the Animal and Plant Quarantine Agency (QIA) in 2000. These devices were classified approximately 1,400 categories as instruments, supplies, artificial insemination apparatus, and other categories. Each of these devices was assigned to four regulatory grades by the QIA in 2007. The ranking system for veterinary medical devices was implemented in 2014 with 820 products from 162 companies registered by that year. However, in vitro diagnostic devices (IVDDs) for animals were managed as medical devices and biological medicine. In vitro diagnostic reagents for treating infection diseases are not subjected to either a classification or grading system. Veterinary medical devices are currently exempt from good manufacturing practices (GMP) and device tracking requirements. Due to gradual growth of the domestic veterinary medical devices market since 2008, regulation of these devices should be improved with re-examination of IVDDs and GMP certification for the effective operating system.

Well-established standards and specifications for medical devices not only provide clarity and consistency in licensing processes but also secure device safety and effectiveness. This study reviewed regulatory standards and specifications for veterinary medical devices in Korea based on data obtained through analyses of those medical devices. General standards for electromechanical, electromagnetic, and biological safety and individual standards for 76 electric and 70 general medical device products have been established by the Korean Ministry of Food and Drug Safety. However, the first standards and specifications for veterinary medical devices were established in March 2000 for two products (disposable needle and syringe). Similar to the large number of standards for medical devices, there have been general standards for safety and individual standards for 72 veterinary medical devices (27 electric medical devices, 12 non-electric medical devices, 10 medical supplies, and 23 other types) established since 2014. These new standards considered, among other aspects, the devices' applications, usage characteristics, and industrial environment. To date, the establishment of standards and specifications for veterinary medical devices remains limited. This study suggests that improvements should be made to the regulation of general and individual standards associated with various veterinary medical instruments, supplies, and in vitro diagnostic medical reagents.

To evaluate the effect of anabolic steroid(AS) on body composition and protein metabolism in malnourished CAPD patients, 7 CAPD patients who were proved to be malnourished by subjective global assessment received 200mg of AS, nandrolone decanoate, by intramuscular route monthly for 5 months. We analyzed the body composition, biochemical nutritional markers, plasma and dialysate amino acids(AA) before and after administration of AS. The mean age was 53.6+/-11.5 years, the sex ratio was 2:5, and the duration of CAPD was 28.5+/-18.7 months. Two patients were diabetics. Five months after AS administration, %lean body mass seemed to increase from 52.6+/-11.7 to 57.3+/-11.0%(P>0.05), but there were no significant changes in body weight and body mass index. Serum insulin-like growth factor-I (172.4+/-88.5 vs. 204.1+/-85.8ng/ml, P<0.05) and transferrin(213.6+/-55.4 vs. 239.0+/-55.3mg/dl, P<0.05) were significantly increased, and serum total CO2(31.1+/-4.5 vs. 25.9+/-2.5mM/L, P<0.05) were significantly decreased. Urea nitrogen appearance(4.0+/-2.0 vs. 3.6+/-1.6g/ day) seemed to be decreased. Both plasma essential AA(EAA) level(738.3+/-206.5 vs. 492.5+/-187.2micromol/L, P<0.05) and peritoneal EAA loss(565.0+/-186.1 vs. 377.4+/-113.9micromol/day, P<0.05) decreased significantly after administration. Plasma total and non- essential amino acids(NEAA) level tended to be increased and peritoneal total and NEAA loss seemed to be decreased without statistical significance. In conclusion, AS seems to have anabolic effect and be useful in the correction of malnutrition in CAPD patients.
