PURPOSE: To evaluate the characteristics of CT findings in differential diagnosis of cervical lymphadenopathy. MATERIALS AND METHODS: We evaluated CT findings of histopathologically proved 32 cases of tuberculous lymphadenitis, 12 cases of nodal lymphoma, 29 cases of metastasis from March 1986 to Dec. 1992, retrospectively. We analyzed age and sex distribution, location of lymphadenopathy, internal nodal density, feature of contrast enhancement, extracapsular spread and nodal calcification. RESULTS: Tuberculous lymphadenitis was more preponderant in young female (mean;32) and CT showed internal low density(91%) with irregular thick marginal enhancement(46.9%), predilection for spinal accessory node(71.9%), and nodal calcification(5/32). Nodal lymphoma showed predilection for internal jugular chain (100%) and had conglomerated homogeneous internal node structures(83%). Metastasis showed old male preponderance (mean :52 years), predilected at internal jugular chain(89.7%),internal low density(93.3%) with regular thin marginal enhancement(44.8%), extracapsular spread(41.4%), and nodal calcification(2 cases of nodal metastasis of papillary type thyroid cancer). CONCLUSION: We concluded that CT evaluation of the chracteristics of lymphadenopathy is helpful for differential diagnosis of cervical lymphadenopathy.

Familial lichen planus is an uncommon disease, and there are 104 cases reported in the English literature. Several theories regarding the etiopathogenesis of lichen planus have been proposed. However, immunological mechanisms and genetic susceptibility have been emphasized the most. Several reports showed HLA analysis in lichen planus patients, and recently 2 cases have revealed an increased frequency of DR1 antigen in patients with lichen planus compared to a control group. We observed two brothers with typical skin lesions of lichen planus of almost simultaneous onset. We confirmed lichen planus by skin biopsies in both brothers and analyzed HLA typing. We also observed the occurrence of DR1 antigen in both of them.

For the improvement of denture fitness of changed residual ridge, denture liner can be used. Denture liner should be very stable physically in various environments of the mouth as well as be bonded strongly with denture resin. In this study, the specimens bonded with four kinds of soft denture liner and three kinds of hard denture liner were used to test the physical properties of the liners. All experimental groups were stored in 37+/-1degrees C distilled water for 24hours, followed by thermocycling between 15degrees C and 45degrees C with 15 second dwell time. 1000, 2000, 3000 cycles of thermocycling were excuted and physical properties were measured by Instron Universal Testing Machine. The obtained results were as follows: 1. In tensile bond test of soft liners, it was shown that both of Molloplast-B(R) specimens before and after thermocycling had the highest tensile strength, and in case of hard liners, Dura-liner II(R)speimen had the highest tensile strength before and after thermocycling. Depending on thermocycling, Soft-Relining(R), Denture-Relining(R),Molloplast-B(R), Coe-soft(R) and Kooliner(R) specimen showed significant difference(p<0.05). 2. In strain test of soft liners, it was shown that Molloplast-B(R) specimen before thermocycling and the Coe-soft(R) after thermocycling showed highest results, and in case of hard liners, the Dura-Liner II(R) speimen before and after thermocycling had the highest result. Depending on thermocycling. Denture-Relinig(R). Molloplast-B(R) and Dura-Lner II(R) specimen showed significant difference(p<0.05). 3. In Maximum distance test of soft liners, the Molloplast-B(R) specimen before thermocycling and the Coe-soft(R) after thermocycling showed highest results, and in case of hard liners, the Dura-Liner II(R) specimen before and after thermocycling showed highest results. Depending on thermocycling, Denture-Relining(R), Molloplast-B(R) specimens showed significant difference(p<0.05). 4.In elasticity test of soft liners , the Molloplast-B(R) specimen before and after thermocycling showed highest results, and in case of hard liners, the Dura-Liner II(R) specimen before thermocycling and the Tokuso-Rebase (R) after thermocycling showed highest results. Depending on thermocycling, Soft-Relining(R) , Molloplast-B(R) specimens showed significant difference(p<0.05).

OBJECTIVETo observe the effect of Tiaozhi Jiangtang Tablet (TJT) on insulin resistance (IR) in rats with diebetes mellitus type 2.

METHODSThe model rats of diebetes mellitus were induced by intraperitoneal injection of streptozotocin (30mg/kg) and feeding with high lipid forage. The rats in the TJT group were treated with TJT and those in the metformin group treated with metformin as positive controls. The glucose infusion rate (GIR) was detected by glucose clamp technique after treatment for 8 weeks. At the same time, fasting blood glucose ( FBG), fasting insulin ( FINS), free fatty acids ( FFA), total cholesterol ( TC), triglyceride (TG), and high-density lipoprotein cholesterol (HDL-C) were measured respectively, and insulin sensitivity index (ISI) and HDL-C/TC calculated. The changes of insulin sensitivity and lipid metabolism were evaluated.

RESULTSTC, TG, HDL-C/TC, FINS, and FFA significantly reduced in the TJT group as compared with those in the control group, while ISI and GIR significantly increased, the effects of TJT were similar to those of metformin.

CONCLUSIONTJT is effective in increasing insulin sensitivity and improving glucose and lipid metabolisms in rats with diebetes mellitus type 2.

PURPOSE: The purpose of this study was to examine the factors influencing glass particle contamination in single dose glass ampules upon opening. METHOD: The study was single case experimental design. Different methods of opening ampule (hand, wooden stick), different sizes of ampules(1cc, 2cc) and different sizes of needles(17gauge, 23gauge, 5micrometer filter) were evaluated. Eighteen ampules were randomly assigned in each group. The number of glass ampule particles > or =10micrometer was counted by microscope. RESULTS: There was no significant difference in the number of particles aspirated by opening methods. But number of glass particles was much lower when using 1cc ampules rather than 2cc ampules and was also much lower when using smaller size needles and needles which include a 5micrometer filter rather than larger size of needles. CONCLUSION: We suggest that larger bore or unfiltered needles increase the risk of aspirating more glass particles than smaller bore or filter needles. In addition, these data show that a wooden stick can be used as a method opening glass ampules.

PURPOSE: Intussusception is a common cause of intestinal obstruction in children. While most patients can be treated by enema reduction, about 20% require surgery. We investigated the usefulness and feasibility of laparoscopic surgery and the intraoperative risk of bowel resection. METHODS: We retrospectively reviewed pediatric patients who underwent surgery for intussusception from 2010 to 2017. We collected data for age, gender, body weight, associated symptoms, duration of symptoms, white blood cell count, operating time, and postoperative complications. RESULTS: Of 155 patients, 37 (23.8%) underwent surgery due to enema reduction failure in 29 (78.3%), recurrence in 6 (16.3%), a suspicious lead point in 1, and suspicious ischemic change observed on ultrasonography in 1. The mean age was 26.8±18.9 months (range, 3.5~76.7 months), and the mean body weight was 12.9±3.9 kg (range, 5.4~22.2 kg). Laparoscopic surgery was successful in 29 patients (78.4%), and 7 (18.9%) needed bowel resection and anastomosis. The mean operating time was 56.7±32.8 min. A lead point was found in 3 patients in the bowel resection group (p=0.005); in addition, the operating time and hospital stay were longer in this group. There were no intra- or postoperative complications. CONCLUSION: Laparoscopic surgery was successful in 78.4% of the patients with a short hospital stay and early oral intake. The only predictive factor for bowel resection was the presence of a lead point. Laparoscopic surgery may be an optimal treatment intervention for children with intussusception, except for those who show initial peritonitis.

Amyloidosis is a disease complex associated with deposition of insoluble filbrillar protein in various tissues of the body. Cutaneous lesions are present in up to 40 % of patients with primary and myeloma associated systemic amyloidosis. We present a case of systemic amyloidosis associated with multiple myleoma occuring in 54-year-old male who had waxy papules with petechiae on nasola bial fold, postauricular area, and cheek. The diagnosis was confirmed by Congo red stain, electron microscope, immunelectrophoresis, Bence-Jones proteinuria, immunoperoxidase stain, and bone marow biopsy.

Novel methods producing supplementary and prosthetic material by cutting or discharge processing via computer design have been proposed as alternatives for traditional casting methods and are being utilized for commercial purposes. The CAD/CAM system used in dentistry can be classified into three-dimensional input of target values, restoration design, and material processing. The marginal fidelity in production of In-Ceram core has important clinical implications and is a key consideration issue in CAD/CAM production as well. Through this research, the author arrived at the following conclusion after conducting comparison analysis of marginal fidelities between the In-Ceram core produced via CAD/CAM and that produced through the traditional method: 1. In the cases of mesial, distal, and lingual margins, the core margins via CAD/CAM produced lower values than those via the traditional method, but the differences were found to be statistically insignificant. 2. In the case of labial flange, the core margins via CAD/CAM produced lower values than those via the traditional method and the differences were found to be statistically significant. (p<0.05) 3. In comparision with overall marginal fidelity, the core margins via CAD/CAM produced lower values than those via the traditional method, but the differences were found to be statistically insignificant. 4. Among the core margins produced via the traditional method did not have statistically significant differences but for those produced via CAD/CAM had statistically significant differences between labial and lingual sides and between labial and mesial sides.
