We have studied the genetic differences among four isolates of Trichinella including a new strain of Trichinella spiralis (ISS 623) recently found from a human case who took a badger in Korea. Because they have a different host origin and came from geographically separated regions, we supposed the genetic pattern of the isolates might be different as had been previously reported. It was analysed by PCR-RFLP analysis of the rDNA repeat that can readily distinguish a species or strain from others. Isolated genomic DNA of each isolate of Trichinella larvae was amplified with ITS1 specific primers and digested with restriction endonucleases. The PCR product of ITS1 was confirmed using Southern blot analysis to be a 910 bp fragment. The restriction fragments of each isolate had variable patterns when it was digested with Rsa 1 only. According to the RFLP patterns, the estimated genetic divergence between each isolate was different. In conclusion, four isolates of Trichinella including a new strain of T. spiralis obtained from a Korean patient may have genetic differences in the ITS1 region and the Shanghai isolate was genetically more similar to the Japanese unknown isolate than others in the ITS1 region.

The purpose of this paper is to study the effects of anti-inflammatory agents on the blood-aqueous-berrier in experimentally induced uveitis. 10% solution of sodium fluorescein was injection intravenously in the ear vein of rabbits (0.25 ml/kg) and fluorescein curve was drawn after the method of Amsler and Huber. Experimental uveitis was induced by the injection of 0.2 ml of human serwn into the vitreous body. After uveitis had been induced. three kinds of anti-inflammatory agents-Prednisolone, Benzyron and Methotrexate-were Biven oralIy. In control animals in which no uveitis was induced, no changes in fluorescein curve were demonstrated before and after the administrations of drugs. In animals with uveitis, maked increases of the blood-aqueous barrier were noted. When Benoyron and Prednisolone were given to these animals, normaliration of the fluorescein curves were demonstrated. Methotrexate had no effects on the fluorescein curves in uveitis animals, showing no improvements in the permeability of uveal vessela. This ineffectiveness seemed to be due to the resistance of rabbits to methotrexate.

Early MRI and arthroscopic findings were compared to evaluate the efficacy of the former for patients, who upon physical examination, were diagnosed with possihle acute ACL tears. MRI, taken between 1-21 days after injury, had to reveal complete ACL tears and arthroscopic surgery should have taken place 3-12 weeks after the injury for patients of this prospective study. Fifty such cases were initially catagorized according to five MRI patterns. Types I to V were separated by the following ACL tear characteristics: Enlarged and diffusely increased in signal, horizontally oriented, non-visualized, discontinuous and vertically oriented. The cases were then divided into two groups of arthroscopic findings; Group A included cases of complete ACL tearing and group B included those with intact or minimally torn ACLs. Of MRI types I through V, there were 31, 9, 5, 4, and I cases of each respectively. 37 cases resulted in complete ACL tears (21 type I, 6 type II, 5 type III, 4 type IV and 1 type V) and 13 cases were catagorized into group B, 10 of which had pattern type I and 3 of which had pattern type II. As result, types III, IV and V had a 100% Positive Predictive Value (PPV) whereas types I and II together had a 67% PPV vaiue. Division of the cases into the five pattern types in early MRI proved valuble for possible cases of acute ACL tears. MRI pattern types III, IV and V were correlated with definite complete ACL tears. However, caution must be taken for types I and II, the majority of the cases, for which there exists a significant possibility for misdiagnosis and consequently unnecessary arthroscopic surgery.

BACKGROUND: Atopic dermatitis, characterized by dry, flasky, easily irritated skin, is the most common form of dermatitis seen during childhood. Infants with atopic dermatitis and other eczematous conditions need special dermatologic care to hydrate their skin and to minimize contact with irritants or allergens. OBJECTIVE: The purpose of our study is to evaluate the safety and efficacy of the skin products developed for children. METHODS: Twenty-eight normal children and 26 children with atopic dermatitis were evaluated clinically after using following commercal skin products : (lotion, cream, shampoo, soap, face wash wash) for 2 weeks. Water content of the skin of 14 volunteers was measured serialy over 8 haurs at 2 hour intervals after the application of each skin product. The skin pH of 16 volunteers was also measured serialy over 60 minutes at 30 minute intervals after application. We performed visual skin erythema grading, skin erythema grading by dermaspectrometer, transepidermal water loss measurement, skin water content measurement, and keratinocyte morphology observation by D-squame after the application of the skin products to 13 volunteers for 4 days.

PURPOSE: The purpose of this study is to investigate the postoperative high order aberration after LASEK and to evaluate the effects of LASEK on high order aberration using larger and blend zone ablation. METHODS: Twenty patients out of 28 patients who received treatment were followed up for 3 months. In each case, one eye received conventional ablation LASEK and the other eye received larger and blend zone ablation LASEK. Preoperative and postoperative RMS (root mean square) of Bille aberration maps measurements were made with WaveScan Wavefront(TM) system (VISX, Santa Clara, U.S.A.). RESULTS: RMS of Bille aberration maps at post operation 1 month and post operation 3 months displayed a statistically significant increase compared with preoperative value. (p<0.05) In post operation 3 month, larger and blend zone ablation LASEK treated eyes displayed a statistically significant lower post operative RMS compared to those of conventional ablation LASEK.(p<0.05) CONCLUSIONS: High order aberrations at post operation 1 month and post operation 3 months increased compared with preoperative value. High order aberration after LASEK with larger and blend zone ablation are less pronounced compared to those associated with conventional ablation LASEK. By using larger and blend zone ablation it is possible to minimize the high order aberration of the eye and improve visual results for patients undergoing LASEK.

PURPOSE: The aim of this study was to evaluate the feasibility and safety of our antivenin treatment protocol for patients with Korean Viperidae envenomation. METHODS: We developed an antivenin treatment protocol for Korean Viperidae envenomation, based on previous data, and applied this treatment to the enrolled patients. In brief, antivenin was not used for patients with grade 0. Patients with grade I and II received one vial of antivenin. Those with grade III and IV received two and three vials of antivenin, respectively. Adult patients who visited the emergency department (ED) after receiving a snakebite between July 2008 to August 2010 were included. Follow ups were performed at 24 hours, 7 days, and 28 days after the snakebite. RESULTS: A total of 62 patients were enrolled. At the initial evaluation, 6 patients (9.7%) were grade 0, 47 patients (75.8%) were grade I, and 9 patients (14.5%) were grade II. Upon the follow-up evaluation, 14 patients (29.8%) progressed from grade I to grade II and 2 patients (22.2%) progressed from grade II to III. Coagulopathy developed in 5 patients (8.0%) and rhabdomyolysis in 5 patients (8.0%). Urticaria developed in 2 patients (3.2%) and cellulitis in 3 patients (4.8%) as delayed complications. As an antivenin-related complication, serum sickness developed in only 1 patient (1.6%). There were no severe complications and all clinical and laboratory abnormalities disappeared within 28 days. CONCLUSION: Our antivenin treatment protocol was feasible and safe. To confirm our data, multicenter validation studies are needed.

This study was aimed to furnish the data of facial bone fracture which was related regional and social environment and to aid diagnosis and treatment of the fracture. This is the retrospective and clinicostatical study on 625 patients with facial bone fracture. The patients were treated in the Dept. of Oral and Maxillofacial Surgery of Wonkwang University Hospital from Jan. 1, 1993 to Dec. 31, 1997. The result were as follows : The facial bone fractures occured most frequently in the twenties(32.3%) and male were predominent(77.4%) than female. The most frequent etiologic factor of facial bone fracture was fall down(42.8%) and midface fracture was traffic accident(63.4%). The most common site of fracture was symphysis(51.1%) and angle(29.7%), condyle(27.5%), ZMC(13.4%) were next in order of frequency. Of the 626 patients, 590 patients(89.5%) were treated with open reduction and only 36 patients(10.5%) were treated with closed reduction. In the blow, the ratio of angle fracture(50%) is especially high(the overall ratio 29.7%) and in the Out car TA, the ratio of ZMC fracture(34.6%) is especially high(the overall ratio 13.4%). In the fall-down, the ratio of symphysis(58.4%) and condyle fracture(33.6%) is especially high(the overall ratio 51.1%, 27.5%). Postoperatives complication were found in 35(5.6%) of 626 patients, in which mouth opening limitation(3%) was the most common. Above results suggest that early diagnosis and treatment of fracture site, systemic condition and associated injuries are nessary, and cooperative treatment with medical department should be performed.

Hypoglossal nerve palsy after general anesthesia is an exceptionally rare complication, which has varied etiology. We present a case of unilateral hypoglossal nerve palsy resulting from repeated airway intervention for general anesthesia. A 57-year-old woman was scheduled to undergo modified radical mastectomy. During endotracheal intubation, the patient had Cormack's grade III-a severe airway condition. After the first intubation attempt failed, the intubation was attempted a second time using a stylet inside the endotracheal tube with cricoid pressure; this attempt was successful. In the evening of the operation day, the patient complained of dysarthria and dysphagia. Physical examination revealed deviation of the tongue to the right, which may have been caused by traumatic hypoglossal nerve injury. This case reviews the pathophysiology, prevention, and management of hypoglossal nerve palsy.
