There has been considerable controversy in the treatment of acute grade 3 injuries of acromioclavicular joint. Neviaser reported that the possibility of a latent degenerative arthritis occurring in the acromioclavicular joint as the result of passing Kirschner wire through the joint was more theoretical than real and any changes that may take place in the acromioclavicular joint were the result of trauma. The acromioclavicular joint and the articular disc were not disturbed at the time of operation in Neviaser technique, but we excised the articular disc that were torn for the purpose of preventing acromioclavicular joint from degenerative arthritis. We had treated 26 cases of grade 3 injuries of acromioclavicular joint with modified Neviaser technique from June 1990 to May 1994 at the Pohang St. Mary’s Hospital. The results were as follows. 1. The clinical results by Weitzman were consisted of 18 cases(69%) of excellent, 6 cases(23%) of good, 2 cases(8%) of fair and 0 case(0%) of poor. 2. Loss of reduction was 1.6mm by stress views of final reviews and didn’t affect to functional result. 3. There were no cases of redislocation of acromioclavicular joint after removal of Kirschner wires. 4. There were no cases of degenerative arthritis of acromioclavicular joint in final review. There result suggest that excision of the articular disc that were torn may be helpful in preventing acromioclavicular joint from degenerative arthritis.

The purpose of this study was to assess the expression of ICAM-1, VCAM-1 and PECAM-1 in allergic and chemical conjunctivitis. The allergic and chemical conjunctivitis were induced in C57BL/6 mouse by compound 48/80(C48/80) and 2% characterized clinically by blepharospasm 100%, chemosis 80%, injection AgNO3, respectively. The allergic conjunctivitis was characterized clinically by blepharospasm 100%, chemosis 80%, injection, 40%, mucous discharge 20%, but the chemical conjunctivitis by blepharospasm 80%, chemosis 60%, infection 40% and no mucous discharge at 30 minute after topical application. On the endothelial cells, ICAM-1 was expressed from 1 to 48 hours, VCAM-1 from 6 to 72 hours and PECAM-1 from 1 to 72 hours in allergic conjunctivitis. In chemical conjuctivitis, the expression of ICAM-1 was observed from 6 to 72 hours. The expression of VCAM-1 was observed from 24 and 72 hours. The expression of PECAM-1 was demonstrated from 6 to 72 hours. The expression of cell adhesion molecules, particulary VCAM-1 and PECAM-1, was slighter in chemical conjunctivitis compared to allergic conjunctivitis. In conclusion, experimental allergic and chemical conjunctivitis demonstrate that cell adhesion molecules play a role in part in ocular inflammation and that there are differences between the adhesion molecule expression of two types of confunctivitis.

BACKGROUND: Since a change in venous capacitance significantly alters venous return and thus affects cardiac output, it is important to know the effects of vasodilators on venous capacitance. The purpose of this study was to examine the effects of sodium nitroprusside and nitroglycerin on venous capacitance during induced hypotension in halothane anesthetized dogs. METHODS: Fourteen mongrel dogs(SNP group: 7, NTG group: 7), weighing 10~15 kg, were anesthetized with N2O 1.5L/min-O2 1.5L/min-halothane 0.5vol%. Each dog received only one drug. In dogs anesthetized with N2O-O2-halothane, mean arterial pressure(MAP) was decreased by 15%(mild hypotension) and 30%(deep hypotension) of control value by sodium nitroprusside(SNP) and nitroglycerin (NTG), respectively. Venous capacitance was assessed before and during induced hypotension by measuring mean circulatory filling pressure(MCFP). MCFP was measured after arresting the circulation by tightening of superior vena cava and inferior vena cava snares simultaneously. RESULTS: As compared with MCFP before induced hypotension, MCFP was significantly decreased by SNP at deep hypotension and NTG at mild hypotension and deep hypotension. As compared with MCFP at mild hypotension, MCFP at deep hypotension was significantly decreased by NTG and SNP, respectively. CONCLUSIONS: These results suggest that NTG has potent venodilating effect at mild and deep induced hypotension, whereas SNP has venodilating effect only at deep induced hypotension.

Purpose:
To confirm that the phaco chop method using an illuminated chopper (iChopper; Oculight, Seongnam, Korea) can reduce cataract surgery complications, and that even beginners can safely and effectively perform phaco chop.
Methods:
We retrospectively analyzed the medical records of the first 30 phaco chop cases using illuminated chopper of four cataract surgeons. Four ophthalmologists had a variety of empirical backgrounds, from those who have experienced more than 10,000 cataract surgery, to beginners who have experienced 20 cataract surgery.
Results:
Of the total 120 eyes, two eyes (1.67%) had posterior capsule rupture. The chopping method was changed from phaco chop to stop and chop in three eyes (2.5%) including one eye with brown cataract with pseudoexofoliation syndrome and two eyes with nuclear opacity grade ≥5.
Conclusions
The rates of posterior capsule rupture of phaco chop using an illuminated chopper were very low in four surgeons with various experiences and who became proficient shortly in phaco chop.

OBJECTIVE: To determine overall handgrip strength (HGS), we assessed the short-term change of HGS after trigger point injection (TPI) in women with muscular pain in the upper extremities by comparison with established pain scales. METHODS: The study enrolled 50 female patients (FMS with MPS group: 29 patients with combined fibromyalgia [FMS] and myofascial pain syndrome [MPS]; MPS group: 21 patients with MPS) who presented with muscular pain in the upper extremities at Konyang University Hospital. In addition, a total of 9 healthy women (control group) were prospectively enrolled in the study. We surveyed the three groups using the following established pain scales: the Fibromyalgia Impact Questionnaire (FIQ), the 36-Item Short Form Health Survey (SF-36), and the Short Form McGill Pain Questionnaire (MPQ). HGS was measured in both hands of study participants using a handgrip dynamometer. We performed TPI (0.5% lidocaine, total 10 mL, injected at the pain site of upper extremities). After 20 minutes, we remeasured the patient's HGS and MPQ score. RESULTS: ANOVA analysis was conducted among groups. Based on Tukey multiple comparison test, the majority of FIQ and SF-36 subscales, total FIQ and SF-36 scores, MPQ and HGS were significantly different between FMS with MPS and the other groups. There was no statistically significant difference between MPS and control groups. Higher HGS was positively associated with enhanced physical function, negatively associated with total FIQ and MPQ scores, and positively associated with the total SF-36 score calculated using Spearman correlation. Post-TPI MPQ decreased and HGS increased. In patient groups, a negative correlation was found between MPQ and HGS. CONCLUSION: The HGS test might potentially be a complementary tool in assessing the short-term treatment effects of women with muscular pain in the upper extremities.

Patients undergoing maintenance dialysis show an increased susceptibility to tuberculosis because host immunity is decreased secondary to malnutrition, impaired cellular immunity, acidosis and etc. Extrapulmonary tuberculosis is more prevalent in patients with end stage renal disease than in normal subjects. Among the extrapulmonary tuberculosis in patients receiving hemodialysis, the diagnosis of tuberculous spondylitis is difficult because the symptoms are non specific and attributable to uremia, and the appearance of plain radiographs is often normal during the early phase of the disease. We experienced a case of tuberculous spondylitis in a hemodialysis patient. A 55 years old female admitted with fever, weight loss and back pain. Conventional radiograph of T-spine showed no definite abnormal finding. However, chest CT revealed heterogeneously enhancing soft tissue around the T8 vertebral body and T-spine MRI showed compatible finding to tuberculous spondylitis. She received radical excision of involved vertebra and confirmed tuberculous spondylitis with histologic finding from a surgical specimen. Following the administration of anti-tuberculosis medication(isoniazid, rifampin, pyraziamide, ethambutol) and radical excision, patient's symptom and sign were improved. The patient is maintaining dialysis with anti-tuberculosis medication for 5 months.

Seventeen dogs were treated with L-ornithin-L-aspartate (LOLA; experimental group). Three dogs were treated with lactulose recognized therapy (control group). Following LOLA administration, 15 dogs experienced a significant decrease in ammonia level (p < 0.05) and showed clinical signs of improvement. However, there were no clinical signs of improvement in two dogs, even though the ammonia level decreased. Conversely, the clinical signs of the control group also improved and the ammonia level decreased, although these changes were not significant (p > 0.05). These results suggest that LOLA is an effective drug to treat hyperammonemia in veterinary medicine.

OBJECTIVES: Hearing loss is the most common sensory disorder in humans and genetic causes are estimated to cause more than 50% of all incidents of congenital hearing loss. To develop an efficient method for a genetic diagnosis of hearing loss, we have developed and validated a genetic hearing loss DNA chip that allows the simultaneous analysis of 7 different mutations in the GJB2, SLC26A4, and the mtDNA 12S rRNA genes in Koreans. METHODS: A genotyping microarray, based on the allele-specific primer extension (ASPE) method, was used and preliminary validation was examined from the five patients and five controls that were already known their genotypes by DNA sequencing analysis. RESULTS: The cutoff Genotyping index (GI) of genotyping for each mutation was set up and validated to discriminate among the genotypes. The result of the DNA chip assay was identical to those of previous results. CONCLUSION: We successfully designed the genetic hearing loss DNA chip for the first time in Korea and it would be useful for a clinical genetic diagnosis of hearing loss. Further consideration will be needed in order to examine the accuracy of this DNA chip with much larger patient sample numbers.

The changes of the microorganism composition after therapeutic radiation for oral cancer patients are not well known and the long-term follow-up data are not reported. To obtain basic data for understanding of pathogenesis and prevention and treatment of dental caries and mucositis occuring after radiation therapy, 7 of the oral cancer patients presented at the Seoul National University Oral & Maxillofacial Department between 1997 and 1998 whose treatment plan included radiation therapy were recruited to investigate the changes in bacterial composition(total aerobic count, candida, Staphylococci, lactobacilli, S. mutans, and S. salivarius (mitis, sanguis)) of the saliva before, during, and after radiation therapy. The basic data obtained from this study on identification and composition change of the bacteria in saliva of patients treated with radiation therapy can be used (1) as a reference for deciding on the ideal anti-microbial spectrum of the oral rinsing agent to be used in patients treated with radiation therapy for malignant tumor of the head and neck region. (2) to enhance the understanding of increase of opportunistic infection after immunochemical changes of the saliva and its relation to specific bacterial infection. (3) as a reference in prescribing prophylactic antibiotics in immunodepressed patients after radiation therapy.
