Backgrounds: Thyroid hormones play a fundamental role in the initiation and maintenance of somatic growth in mammalian species, and the insulin-like growth factors(IGFs) occupy a position of central importance in the growth of all tissues. To evaluate the changes in serum insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding proteins in hyperthyroid and hypothyroid patients, sera was obtained from 19 hyperthyroid patients, 9 hypothyroid patients, and 10 healthy volunteers. Methods: IGF-I concentration was determined by radioimmunoassay, and changes in IGFBPs were assesed by Western Ligand Blotting. To evaluate the binding pattern of IGF-I & IGFBPs, autoradiographs were obtained. Results & Conclusion: IGF-I levels were increased significantly in hyperthyroid patients(mean ±SE, 267.88±9.80 ng/ml, p<0.05) and decreased significantly in hypothyroid patients(154.81±1.43 ng/ml, p<0.01) compaired to healthy control group(209.45±.60 ng/ml). Autoradiograph of serum IGFBPs from patients with hyperthyroidism and hypothyroidism did not show any change in the intensity of IGFBP-3 bands(40-45 KD) and IGFBP-1 bands, but in hyperthyroid patients, it showed increased intensity of IGFBP-2 band compared to healthy control group and hypothyroid patients.

Understanding of the adhesion molecules involved in the interaction of gastric cancer cells with peritoneal mesothelial cells (PMC) might provide a useful strategy for interfering with cancer cell implantation to the peritoneum. Since CD44H is a major cell surface receptor for hyaluronate (HA), it may play an important role in mediating cancer cell adhesion to PMC through recognition of mesothelium associated HA. The purpose of the present study was to define the functional significance of CD44H in peritoneal metastasis of gastric cancer cells by using quantitative assays for measuring the adhesion ability to PMC in vitro. CD44 expression in gastric cancer cell lines SNU-1, -5, and -16 were examined by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis. CD44H was expressed in SNU-5 and -16 whereas no significant level of CD44H was expressed in SNU-1. SNU-16 expressed additional high-molecular-weight CD44 isoforms. In the adhesion assay with HA coated microtiter wells, SNU-5 and -16 demonstrated high affinity for HA, with values of 64.6+/-10.5% and 91.1+/-8.8%, respectively. SNU-1 demonstrated no significant binding affinity for HA (p<0.05). For the in vitro binding assay, we used a confluent monolayer of PMC. 2.5x10(4) and 5x10(4) gastric cancer cells labelled with 51 Cr were inoculated into microtiter wells and allowed to adhere for 2 hr. After washing of the unattached cancer cells, adherent cells were lysed with 0.1 N NaOH and the radioactivity was measured in the lysates. SNU-5 and -16 bound to PMC, to the extent of 10.0+/-1.0%, 14.6+/-1.8% and 22.9+/-2.0%, 23.7+/-3.6%, respectively. In contrast, SNU-1 demonstrated lower binding ability(6.4+/- 0.5%, 6.7+/-1.3%, respectively) to PMC. In conclusion, CD44H is at least partly involved in gastric cancer cell binding to PMC, which mediates an important first step of peritoneal implantation.

BACKGROUND: Portable devices for measuring peak expiratory flow(PEF) are now of proved value in the diagnosis and management of asthma and many lightweight PEF meters have become available. However, it is necessary to determine whether peak expiratory flow rate(PEFR) measurements measured with peak flowmeters is accurate and reproducible for clinical application. The aim of the present study is to define accuracy, agreement, and precision of mini-Wright peak flow meter(MPFM) against standard pneumotachygraph. METHODS: The lung function tests by standard pneumotachygraph and PEFR measurement by MPFM were performed in a random order for 2 hours in 22 normal and 17 asthmatic subjects and also were performed for 3 successive days in 22 normals. RESULTS: The PEFR measured with MPFM was significantly related to the PEFR and FEV1 measured with standard pneumotachygraph in normal and asthmatics(for PEFR, r=0.92 p<0.001; for FEV1, r=0.78 ; p<0.001). The accuracy of MPFM was within 10%(limits of accuracy recommeded by NAEP) in all the subjects or 22 normal, mean difference from standard pneumotachygraph being I 6.5L/min(percentage of difference being 2.90%) or 1 0.6L/min(percentage of difference being 1.75%), respectively. According to the method proposed by Bland and Altman, the 95% limits of the distribution of differences between MPFM and standard pneumotachygraph after correction of PEFR using our regression equation were +38.2 and -71.5L/min in all the subjects or -20.49~ + 9.49L/min in 22 normal and was similar to the intraindividual agreements for 3 successive days in normal. There was no statistically significant difference of PEFR measured with MPFM and standard pneumotachygraph among three days(p>0.05) and the coefficient of variation(2.4 1.2%) of PEFR measured with MPFM was significantly lower than that( 5.2 3.5%) with standard pneurnotachygraph in normal (p<0.05). CONCLUSION: This results suggest that the MPFM was as accurate and reproducible as standard pneumotachygraph for monitoring of PEFR in the asthmatic subjects.

PURPOSE: Kissing contusion between the posterolateral tibial plateau and lateral femoral condyle is frequently found in association with a tear of the anterior cruciate liagment (ACL). The purpose of this study was to determine which ligamentous and meniscal tears are associated with kissing contusion. MATERIALS AND METHODS: We retrospectively reviewed the findings depicted by 323 consecutive MR images of the knee and confirmed at arthroscopy. For the diagnosis of disruption, ligaments, medial menisci (MM) and lateral menisci (LM) were evaluated using accepted criteria. We compared the prevalence and location of meniscal and ligamentous tears between group I (44 knees with kissing contusion) and group II (279 knees without kissing contusion). For statistical analysis the chi-square test was used. RESULTS: ACLs were torn in all 44 knees (100%) with kissing contusion, and 78 (28%) of 279 without kissing contusion. There were ten medial collateral ligament (MCL) tears (23%) in group I, and 17 MCL tears (6%), five lateral collateral ligament (LCL) tears (2%) and ten posterior cruciate ligament (PCL) tears (4%) in group II. In group I, meniscal tears were found in 22 MM (50%) and in 19 LM (43%), while in group II, they occurred in 128 MM (46%) and 128 LM (46%). In group I, 17 (77%) of 22 MM tears and 13 (68%) of 19 LM tears were located in the posterior horn, while in group II, the corresponding figures were 97/128 (76%) and 60 of 128 (47%). The differing prevalence of ACL and MCL tears between the groups was statistically significant (p<0.05), but differences in the prevalence and location of meniscal tears were not (p>0.05). CONCLUSION: Although kissing contusion was a highly specific sign of ACL tears, its presence was also significant among MCL tears. There was no signifficant difference in meniscal tears with or without kissing contusion.

To evaluate the additive efficacy of postoperative low dose 5-FU subconjunctival injection, we analyzed 43 patients[43 eyes]who had undergone trabeculectomy or triple surgery with intraoperative MMC for 2.5~3min.18eyes[case group =MMC 5-FU group]of 43 eyes had postoperative low dose 5-FU injection additionally and 25 eyes[control group =MMC group]of which had only undergone intraoperative MMC. The mean[+/-SD]follow-up periods were 13.6 +/-5.3 months in MMC 5-FU group and 12.1 +/-3.6 months in MMC group.There was no statistically significant difference in preoperative IOP between the two groups[p>0.05].Mean postoperative intraocular pressures were 12.9 +/-4.2 mms of mercury in MMC 5-FU group and 13.3 +/-4.4 mms of mercury in MMC group at 12 months postoperatively[p>0.05]. Kaplan-Meier survival analysis showed that the cumulative success rates at 1.5 year were 82.6%and 87.2%in the case and control groups, respectively[p>0.05].Of the postoperative complications, corneal epithelial defect was more frequent in MMC 5-FU group[p<0.05]. In conclusion, postoperative injection of low dose 5-FU additionally did not have an additive effect on the IOP control in patients undergone MMC applied filtering surgery. We may need additional postoperative injection of higher dose of 5-FU.Or, we may need to individualize the duration of application or the concentration of intraoperative MMC to begin with.

The role of the periosteum on osteointegration of Bio-Oss(R)(Geistlich, Wolhusen/Switzerland) was studied in rabbit calvarial defect. 12 New Zealand white male rabbits between 2.8 and 4 kg were included in this randomized, blinded, prospective study. Each rabbit was anesthetized with Ketamine HCl(5 mg/kg) and Xylazine HCl(1.5 ml/kg). An incision was made to the bony cranium and the periosteum was reflected. Using a 6-mm trephine bur(3i. USA), four 8-mm defects were created with copious irrigation. The defects were classified into barrier membrane(Tefgen(R), Lifecore Biomedical, Inc, U.S.A.) only group as a control, Bio-Oss(R) with barrier membrane group, Bio-Oss(R) with periosteum covering group, and Bio-Oss(R) without periosteum covering group. There were 2 rabbits in each group. The wound was closed with resorbable suture materials. Rabbits were sacrificed using phentobarbital(100 mg/kg) intravenously at 1, 2, and 4 weeks after surgery. The samples were fixed in 4% paraformaldehyde, and decalcified in hydrochloric acid decalcifying solution(Fisher Scientific, Tustin, CA) at 4degrees C for 2-4 weeks. It was embedded in paraffin and cut into 6 micrometer thickness. The sections were stained with H & E and observed by optical microscope. The results were as follows; 1. The periosteum played an important role in osteointegration of Bio-Oss(R) in bone defects. 2. When the periosteum remained intact and Bio-Oss(R) was placed on the defect, Bio-Oss(R) with periosteum covering has been incorporated into the newly formed bone from 2-week postoperatively. 3. When the periosteum was removed at the surgical procedure, invasion of connective tissue took place among the granules, and new bone formation was delayed compared to periosteum covering group. Therefore, when the bone grafting was performed with periosteal incision procedure to achieve tension-free suture, the integrity of the overlying periosteum should be maintained to avoid fibrous tissue ingrowth.
