The purpose of this study was to evaluate the systemic and local production of immunoglobulins and their levels in patients with periapical cysts using Enzyme - Linked Immunosorbent Assay. Streptococcus sanguis, Bacteroides gingivalis, and Bacteroides intermedius were grown for use as antigen and they were harvested by centrifugation. The patients were divided into two groups: patients of periapical cysts and normal control. 5 patients of each group were selected and their blood were obtained via intravenous puncture prior to surgical operation. Sera were prepared by centrifugation of each blood samples. Cyst fluid were aspirated from cystic cavity and cyst wall were excised at operation. Control tissue were also excised at extraction site of impacted wisdom teeth from normal control. Each tissue was prepared by homogenization and centrifugation. Then antibodies of each sample were measured by modified ELISA. The following results were obtained: 1. Serum IgG and IgM levels were not significantly different between patients with periapical cyst and normal control. 2. IgG and IgM levels of cyst fluid to Bacteroides gingivalis and Bacteroides intermedius were significantly higher than those of serum of patients with periapical cyst, but there was no significant difference to Streptococcus sanguis. 3. IgG and IgM levels of cyst wall to Bacteroides gingivalis and Bacteroides intermedius were significantly higher than those of control tissue, but there was no significant difference to Streptococcus sanguis. 4. IgG and IgM levels in cyst fluid and IgG levels in cyst wall were highest to Bacteroides gingivalis, and IgM levels in cyst wall were highest to Bacteroides intermedius.

Background: This study aimed to determine the prevalence and factors related to needle stick injuries (NSIs) and to assess related safety measures among a sample of Iranian nurses. Methods: In this cross-sectional study, a random sample of 168 registered active nurses was selected from different wards of one of the hospitals of Shiraz University of Medical Sciences (SUMS). Data were collected by an anonymous questionnaire and a checklist based observational method among the 168 registered active nurses. Results: The prevalence of NSIs in the total of work experience and the last year was 76% and 54%, respectively. Hollow-bore needles were the most common devices involved in the injuries (85.5%). The majority of NSIs occurred in the morning shift (57.8%) and the most common activity leading to NSIs was recapping needles (41.4%). The rate of underreporting NSIs was 60.2% and the major reasons for not reporting the NSIs were heavy clinical schedule (46.7%) and perception of low risk of infection (37.7%). A statistically significant relationship was found between the occurrence of NSIs and sex, hours worked/week, and frequency of shifts/month. Conclusion: The study showed a high prevalence of NSIs among nurses. Supportive measures such as improving injection practices, modification of working schedule, planning training programs targeted at using personal protective equipment, and providing an adequate number of safety facilities such as puncture resistant disposal containers and engineered safe devices are essential for the effective prevention of NSI incidents among the studied nurses.

We have performed left lung transplantation followed by ligation of right pulmonary artery in 14 dogs at the Chest Disease Research Institute, Yonsei University College of Medicine from May 1992 to February 1994. Excised left lung was perfused with 1500cc of 4$^{\circ}$C cold Euro-Collin`s[E-C] solution at a pressure of 30cmH2O through main pulmonary artery and preserved in 4$^{\circ}$C cold E-C solution for one hour. Left lung transplantation were proceeded in order of left atrium, left main bronchus, left pulmonary artery and right pulmonary artery ligation as usual method. The femoral artery and pulmonary artery pressures were monitored for more than 5 hours after the transplantations in 14 dogs. Six recipient dogs had elevated mean pulmonary artery pressure to greater than 30mmHg after the left lung transplantation and ligation of right pulmonary artery. The cause of elevated mean pulmonary artery pressure was due to inadequate preservation resulting in ischemic damage to donor lungs in 3 cases, and inadequate surgical techniques in 3 cases. Two recipient dogs without surgical complications died immediate post-operatively due to hemorrhagic shock. The bleeding focuses were LA anastomotic site in one case and femoral artery puncture site in another case. The remaining 6 recipient dogs showed mean pulmonary arterial pressure less than 30mmHg. However, one dog had spontaneous pneumothorax in post-operative 4 days, and another dog had rejection phenomenon in post-operative 5 days which was confirmed by pathologic findings of extracted transplanted lung. One dog succumbed of severe hemoptysis which was due to lung abscess with pin point stenosis of bronchial anastomosis in post-operative 38 days. In conclusion, elevated mean pulmonary arterial pressure greater than 30mmHg in immediate postoperative period can be due to inadequate preservation of extracted lung or poor surgical techniques. And the two dogs succumbed of hemorrhagic shock even though the mean pulmonary arterial pressure was less than 30mmHg. It is thought that careful preservation of the extracted donor lung in 4oC E-C solution and complete surgical techniques are the most important factors early and late complications.

Purpose: Many studies on the time course of inducible nitric oxide synthase (iNOS) gene expression have been performed in the LPS (Lipopolysaccharide)-induced endotoxemic model, but there have been few experimental approaches to continuous peritonitis-induced sepsis model. We conducted this study to establish basic data for future sepsis-related research by investigating the time course of iNOS gene expression and the relationship with the production of inflammatory mediators in the early sepsis model induced by cecal ligation and puncture (CLP). Methods: Male Sprague-Dawley rats were operated on by sing the CLP method to induce of peritonitis; and then, they were sacrificed and samples of blood and lung tissues were obtained at various times (1,2,3,6,9 and 12 h after CLP). We observed the expression of iNOS mRNA from lung tissues and measured the synthesis of nitric oxide, $IL-1{\beta}$, and $TNF-{\alpha}$ from the blood. Results: iNOS mRNA began to be expressed at 3 h and was maintained untill 12 h after CLP. The nitric oxide concentration was increased significantly at 6 h, reached its peak level at 9 h, and maintained a plateau untill 12 h after CLP. $TNF-{\alpha}$ began to be detected at 3 h, increased gradually, and decreased steeply from 9 h after CLP. $IL-1{\beta}$ showed its peak level at 6 h after CLP, and tended to decrease without significance. Conclusion: We observed that the iNOS gene was expressed later in peritonitis-induced sepsis than in LPS-induced sepsis. Nitric oxide and key inflammatory mediators were also expressed later in peritonitis-induced sepsis than in LPS-induced sepsis.

Korean safflower seed has been known to have healing effects on both bone fracture and osteoporosis. On the base of such a notice, this experiment was carried out to explore the effects of safflower seed on bone formation and bone repair. The toxicity test and the effect of Korean safflower seed were evaluated with 60 rats, 3-month old. Forty Sprague-Dawley rats composed of 20 male and 20 female were underwent unilateral tibial defect and then fastened with unilateral fixators. The operated rats were divided into two groups depending on the composition of diet, such as positive control group fed normal diet(C-OP group) and safflower seed group fed 30% of safflower seed diet and 70% of normal diet(S-OP group). Another 20 rats without operation were maintained, each 10 rats were fed either normal diet or 30% of safflower seed diet and 70% of normal diet, and observed the toxicity of safflower seed by measuring weight and urine parameters. Postoperative radiography were taken once in 2 weeks to evaluate callus formation for operated groups and blood collection via heart puncture were carried out once in 3 weeks for 3 groups. The concentration of Ca and Pi in serum were measured using both auto Kit and $^{31}$ P Nuclear Magnetic Resonance(NMR). At present study, no toxic effect was observed from both weight increment and urine index after feeding the safflower seed diet. The comparison of the radiography between C-OP and S-OP group were showed that the safflower seed diet appeared to stimulate the formation of callus in the rat. The ratio of Ca/P in serum was low in S-OP group compared to C-OP group with the auto Kit, but there were no significant differences between two groups (p < 0.05). In addition, the variations of Pi values in NMR examination were also confirmed based on the result of auto Kit. In conclusion, this study implied that safflower seed might influence to bone formation and shorten the periods of remedy by stimulating the calcification of bone

Objectives : There are many kinds of method to evaluate neural decompression during operation. They are direct visual and manual inspection, intraoperative ultrasound, endoscope, intraoperative computed tomography and intraoperative myelography. We used intraoperative myelography to evaluate the proper decompression of neural elements during the decompressive surgery. Methods : We injected 10-20cc of nonionic water-soluble contrast materials through direct puncture site of exposed dura during operation or lower lumbar level or lumbar drain inserted preoperatively. 12 patients were included in this study. They were 7 patients of centrally herniated lumbar disc disease, 1 patient of multiple lumbar spinal stenosis, 2 patients of thoracic extradural tumor and 2 cervical fracture & dislocations. Results : 5 of 12 patients showed remained neural compression through intraoperative myelography, so they were operated further through other approach. Myelographic dye is heavier than CSF, so the dependent side of subarachnoid space was visualized only. In one case, CSF leakage through hemovac was detected, but it was treated only bed rest for 5 days after hemovac removal. Conclusion :Intraoperative myelography is an effective method to evaluate neural decompression during spinal surgery. This technique is easy and familiar to us, neurosurgeons.

Objectives : To describe a technique for percutaneous vertebroplasty of osteoporotic vertebral body compression fractures and to report preliminary results of its use. Methods : The technique was used over a 8-month period in 9 patients with 10 painful vertebral fractures. The technique involves percutaneous puncture of the involved vertebrae with a Jamshidi needle via a transpedicular approach followed by injection of polymethylmethacrylate(PMMA) into the vertebral body. Results : The procedure was technically successful in all patients, with an average injection amount of 5.9 cc per vertebral body. One patient complained of flank pain postoperatively in spite of improvement in back pain caused by the fractured vertebra. Remaining eight patients reported significant pain relief early after treatment. The patients were followed up for 3 to 15 months(average 7.2 months) and demonstrated no recurrence of pain or aggravation of deformity. Conclusion : Vertebroplasty appears to be a valuable tool in the treatment of painful osteoporotic vertebral fractures, providing acute pain relief and early mobilization in appropriate patients. However, it needs to have more extensive prospective clinical study to confirm its definitive role in the management of this condition.
