This study was designed to investigate the mole- cular mechanism of chemokine induction by lipopoly-saccharide(LPS) of E. coli. Chemokine gene expression was evaluated by the reverse transcriptase-polymerase chain reaction(RT-PCR) assay using RNAs isolated either from kidneys of LPS-injected inice or from the mesangial cells stimulated with LPS, IFN-r or TNF-a. LPS was shown to induce interferon gamma(IFN- 7 ) inducible protein 10 (IP-10) and monokine induced by interferon gamma (MIG) in kidney. IP-10 gene expression was induced by LPS and IFN-r, but MIG gene expression was induced by IFN-r in mesangial cell. Chemokines induced by LPS increased splenocyte migration. Sodium salicylate, wortmanin and piperazine blocked LPS mediated chemokine induction suggesting the activation of nuclear factor-a B pathway. It is concluded from this study that mesangial cells are the target of LPS in the renal failure resulting from the systemic infections. LPS induces chemokines directly and/or indirectly in the mesan- gial cells, and these chemokines may associated with renal inflammation.

Dendritic cell (DC)s are protessional antigen presenting cells and they have been used for antitumor immunotherapy or cell vaccines. However therapy using DC is restricted because the number of DC available from tissue is very low. Flt3 ligand (FL) has been known as a hematopoietic growth factor that increases proliferation of hematopoietic stem cells and progenitor cells, and recently it showed inducibility of dendritic cell (DC)s and signiticant antitumor effects in vivo. Thus FL will be frequently used for DC induction and antitumor immunotherapy in future. Here we constructed FL plasmid and studied its in vivo effect. FL plasmids were made by cloning of partial FL cDNA into pcDNA3 plasmid, and gene expression and protein producibility of FL plasmid were confirmed in Renca cells transfected with FL plasmid. Mice were injected with FL plasmid (100ug/mouse) three times and 20 days later mouse spleens were harvested for staining and RT-PCR. There were lots of blastogenic cells in the spleen of mice treated with FL plasmid. FL plasmid also induced DEC205, IL-12 and GM-CSF gene expression in mouse splenocyte. All these data suggest FL plasmid may be used for induction of DC and antitumor therapy as DNA adjuvant.

The compartment syndrome was described by von Volkmann in 1872 and numerous reports have since been published. The anterior tibial syndrome is well known, but the peroneal compartment syndrome is very rare and have some differences in it's etiology, diagnosis and treatment. We experienced a case of the peroneal compartment syndrome developed after playing foot-ball, and treated by fasciotomy with some delay, but obtained a satisfactory functional result.

PURPOSE: To study whether preoperative fasting would influence postoperative prognosis and to measure the variation of the ketone body amount and ketone body ratio, kidney function during the postoperative period in the model of 90% hepatectomy. MATERIALS AND METHODS: Total of 180, seven weeks old, male, specific pathogen free Sprague-Dawley rats, divided into two groups of the fasted and the fed. First, 80 rats were divided into two groups of 40 each; 40 of that were denied food for 48 hours before the operation, other 40 were fed. Following 90% hepatectomy they were investigated by Kaplan-Meier method, drawing a survival curve. Secondly, 100 rats were divided into two groups of 50 each, 50 of that were denied food for 48 hours before the operation, and the other 50 were fed. Following 90% hepatectomy, they were investigated by the method of Student's T-test and Mann-Whitney test on the following: the amount of arterial ketone body in the blood in the blood sampled from abdominal aorta, reading at preoperative 48 hours, at the time of operation, postoperative 6 hours, 12 hours, 24 hours, 48 hours periods. RESULTS: The mean survival time after operation: the fasted group was 53.0+/-3.7 hours and the fed group was 34+/-1.7 hours and it had the statistical significance(p=0.0008). Rats which had long term survival over 72 hours were 14(35%) in fasted group, but only 2(5%) in fed group. In preoperative fasted group arterial ketone body ratio was recovered earlier than fed group and ketone body amount elevated, but in preoperative fed group, there was no significant change in ketone body amount. Blood glucose level lowered in both groups. Blood ammonia was severely increased in preoperative fed group, suggested bad liver function and destruction of muscle. BUN and blood creatinine was elevated in preoperative fed group, suggested lowered kidney function. CONCLUSION: Preoperative fasting has a positive influence on survival of the rats which has acute liver failure induced by 90% hepatectomy, because it could be caused by increased ketone body amount by preoperative fasting.

PURPOSE: To identify the prognostic factors for successful laser iridotomy for acute angle-closure glaucoma (AACG). METHODS: We retrospectively reviewed the medical records of 77 eyes of 77 patients with AACG with initial intraocular pressure (IOP) above 40 mmHg. All of the patients received maximum tolerable medical therapy (MTMT) followed by laser iridotomy. In order to comparatively analyze the factors affecting successful laser iridotomy, an increase in IOP on follow-up was defined as increase in IOP greater than 21 mmHg requiring medical or surgical treatment. RESULTS: Successful laser iridotomy was achieved in 59.7% (46/77 eyes). Thirty-one eyes (40.3%) exhibited increased IOP on follow-up, and of these, 30 eyes developed an increase in IOP within six months after the first attack. The success rate was higher (92.9%) in 42 patients who had greater than 30% IOP reduction by MTMT at the first attack compared to the 35 patients whose IOP reduction was less than 30%, of which 24 eyes (72.7%) showed more than 30% IOP reduction after intravenous hyperosmotic agent treatment (p=0.012). The success rate was higher in patients treated within seven days after the development of symptoms than in those treated after seven days (Odds ratio, 4.51; 95% confidence interval, 1.38 to 14.75). CONCLUSIONS: Our data suggest that we can expect successful IOP control after laser iridotomy in eyes with AACG if the patient can be treated within seven days after the development of symptoms and if the IOP reduction was more than 30% by MTMT.

PURPOSE: The objective of this study was to evaluate fracture strength of collarless metal-ceramic FPDs according to their metal coping designs. MATERIALS AND METHODS: Four different facial margin design groups were investigated. Group A was a coping with a thin facial metal collar, group B was a collarless coping with its facial metal to the shoulder, group C was a collarless coping with its facial metal 1 mm short of the shoulder, and group D was a collarless coping with its facial metal 2 mm short of the shoulder. Fifteen 3-unit collarless metal-ceramic FPDs were fabricated in each group. Finished FPDs were cemented to PBT (Polybutylene terephthalate) dies with resin cement. The fracture strength test was carried out using universal testing machine (Instron 4465, Instron Co., Norwood MA, USA) at a cross head speed of 0.5 mm/min. Aluminum foil folded to about 1 mm of thickness was inserted between the plunger tip and the incisal edge of the pontic. Vertical load was applied until catastrophic porcelain fracture occurred. RESULTS: The greater the bulk of unsupported facial shoulder porcelain was, the lower the fracture strength became. However, there were no significant differences between experimental groups (P > .05). CONCLUSION: All groups of collarless metal-ceramic FPDs had higher fracture strength than maximum incisive biting force. Modified collarless metal-ceramic FPD can be an alternative to all-ceramic FPDs in clinical situations.
