Necrotizing fascitis is a severe soft tissue infection characterized by extensive necrosis of superficial fascia, suppurative fascitis, vascular thrombosis, widespread undermining of surrounding tissues. Accociated systemic problems are widespread undermining of surrounding tissues, Accociated systemic problems are common, with chronic alcoholism and diabetes being most prominent. Most commonly this disease presents in the extremities, trunk, and perineum. Necrotizing fascitis of dental origing is rare and its fulminating clinical course is not well documented in the dental literature. The present report is a case of necrotizing fascitis following vital extirpation of the pulp in a patient with uncontrolled diabetes mellitus and liver cirrhosis. Originally throught to be caused by hemolytic streptococcus organism or stphylococcus aureus, advances in anaerobic culturing have shown it to be a synergistic bacterial infection involving aerobic and ovligate anaerobes. it is relatively rare in relatively rare in haea and neck regions. If it was not diagnosed and treated in early stages, necrotizing fascitis can be potentially fetal, with a mortality rate approaching 40%. It's treatment requires early recognition, prompt and aggressive surgical debriment and proper supportive cares, such as, antibiotic therapy, fluid resuscitation and correction of metabolic and electrolyte disorder, resolving of the underlying systemic disease. Recently, we experienced two cases of necrotizing fascitis in cervicofacial region, One patient was 60 years old male with uncontrolled Diabetes Mellitus and other patient was 48 years old with steroid therapy during 30 years. Local surgical wound healing was successful but, patients were died after admission, because of lung abscess, gastrointestinal bleeding, septic shock and respiration hold.

Objective : Hedyotis diffusa has been used as an arnicancer agent for several decades in oriental medicine. We test whether the methanol extract of the herb affects transcriptional activation factors including NF-κB and AP-l. Methods : 1. HL-60 cells were treated with various concentrations(from 200 to 50ug/ml) of methanol extract and H_2O extract(200ug/ml)of hedyotis diffusa, After 48h later, the cells were tested for viability by MTT assay. 2. The HL-60 cells were treated with 200ug/ml of methanol extract for the indicated periods. First. Nuclear extracts were isolated and incubated with oligonucleotide probe of NF-κB and AP-l. Second. Nuclear extracts were isolated and reacted with p50, p65. c-rel par-Jun, c-Jun, JunB. JunD antibody on ice for 30min. Finally The cell lnates were prepared and analyzed by westem blotting using anti-Fas, anti-FasL and anti-p53 antibdy. Results : l. The methanol extract decreases the viability of human lymphoid origin leukemia HL-60 cells in a dose-depemdemt manner. 2. NF-κB is rapidly activated by the addition of the methanol extract, reaches a peak at 30min and gradually returns to resting level. We confirm tha NF-κB is a heterodimer mainly composed of p65 subunit with c-Rel. 3. Transcriptional activation of AP-1 is detected at 30min and reaches a maximum at lhr after stimulation of the cells with the methanol extract. AP-l is mainly composed with Jur-D and partially Jug-B proteins. 4. the methanol extract of Hedyotis diffusa induces the expression of Fas, Fas ligand and p53 proteins of HL-60 cells in a time dependent fashion. Conclusions : These results suggest that the methanol extract of Hedyotis diffusa exerts anticancer effects to induce the death of human leukomic HL-60 cells via activation of trascriptional factors such a NF-κB and AP-1, increase in expression of Fas mediated signaling proteins, and induction of tumor suppressor gene. p53

This study investigated the efficiency of industrial waste treatment. For this purpose. "A" treatment plant which treats industrial wastes of CN. Cr and alkali was selected. Of these wastes, this study focused on treatment of Cr waste. Results of this study showed that "A" plant did not need to raise the pH to 10.5 to precipitate Cr(OH)₃. There was no difference in Cr concentration while the pH of the waste was maintained to 7~9 using NaOH. The use of Ca(OH)₂ to aid coagulation was not justified. lt failed to improve the effluent quality, but generated more sludge. However, the use of polymer was found to be necessary. It helped lower SS concentration of the waste as well as lower the sludge volum. This study also found that "A" treatment plant overdosed alum. By adding 150~200 mg/L of alum (30~40 % of the actual dose), the same effluent quality was obtained.

This study was performed to investigate the effects of edible oils and fats on the immunobiological responses in ICR male mice. Ten groups of experimental diets, such as sesame oil diet, beef tallow diet, lard oil diet, olive oil diet, corn oil diet, perilla oil diet, rice polishing oil diet, soybeen oil diet, rape seed oil diet, and red pepper seed oil diet were fed adlibitum to the ICR male mice for 27 days. The results of this study were summarized as followings. 1. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes in sesame oil group were increased. However, the increasing rate of body weight and the weight retios of spleen and thymus to body were generally decreased. 2. Hemagglutination titer(HA) and rosette forming cell(RFC) of the beef tallow group and the lard group were significantly lower than the sesame oil group(P<0.01), but the lard group significantly increased Arthus reaction and delayed type hypersensitivity(DTH)(P<0.01). 3. Arthus reaction, DTH, and RFC of the olive oil group were significantly higher than the sesame oil group(P<0.01). 4. DTH of the corn oil group was significantly higher than the sesame oil group(P<0.01) whereas phagochyte activity was significantly lower(P<0.01). But no statistically significant differences were found between the two groups in the humoral immune response. 5. HA, PFC, DTH, RFC, phagocyte activity, and number of leukocytes of the perilla oil group and the rice polishing oil group were significantly lower than the sesame oil group(P<0.01). 6. Both humoral and cellular immune responses, phagocyte activity, and number of leukocytes of the soybeen oil group, the rape seed oil group, and the red pepper oil group were significantly lower than the sesame oil group(P<0.01).

Cells immnunoreactive for somatostatin(SOM) and glucagon(GLU) were investigated in postnatal day 0, 7, 14, 28, 90, 180 and adult canine pancreas using light microscopic immunohistochemistry. Pancreatic SOM-immunoreactive cells were found in pancreatic acini, pancreatic duct, and pancreatic islet gradually. Pancreatic SOM-immunoreactive cells were more located in pancreatic parenchyme than pancreatic islet throughout pancreas by postnatal day 28. But there was change by the postnatal 3 months : pancreatic SOM-immunoreactive cells were more located in pancreatic islet than acini and duct. It is suggested that the number of the SOM-immunoreactive cells may not increase with age apparently. A small number of SOM-immunoreactive cells that showed GLU-immunoreactivity were also observed in canine pancreatic islet. The physiologic consequences of these changes remain to be determined. These results sugegest that SOM in the developing pancreas may relate to the secretion of pancreatic hormones.
