Cyanide poisoning is expected to be antagonized by the administration of oxygen, when it is administered in combination with the conventional cyanide antidote, sodium,thiosulfate. However, the antidotal efficacy and its exact mechanism of oxygen in cyanide poisoning is still a controversial one. To test the effect of oxygen on the antidotal action of thiosulfate ,in cyanide poisoning, author designed this study on the dose-mortality patterns for potassium cyanide in mice. Potency ratios derived from LDso values were compared in groups of mice treated with sodium thiosulfate alone and sodium thiosulfate with oxygen. These results indicated that oxygen enhances the anti-dotal effect of sodium thiosulfate, effectively. This fact demonstrates that oxygen is of importance in the treatment of cyanide poisoning.

BACKGROUND: Even though excellent impression materials are now available for making accurate replication for hard and soft tissue, the numerous dentists have faced lots of obstacles in making simultaneous impressions of multiple abutments. CASE DESCRIPTION: This article describes a modified method of tray fabrication using auto-polymerizing acrylic resin and impression technique for multiple prepared teeth in cases with limitations and difficulties in taking dental impressions. CLINICAL IMPLICATION: This segmental tray technique has several advantages, including higher impression quality, fewer impressions, and being more comfortable for the patient and less stressful for the clinician.

OBJECTIVE: Mycoplasma pneumoniae infection is known as one of the frequent causes of exacerbation of bronchial asthma and it can also be a trigger for the initiation of asthma. However, little is known about the pathogenesis of respiratory M. pneumoniae infection. Furthermore, there is little data on human cytokine production and its involvement in the pathogenesis of M. pneumoniae infection. In order to investigate the immunopathogenesis of M. pneumoniae infection, we investigated the cytokine production in the bronchoalveolar lavage ( BAL ) fluid of patients with M. pneumoniae pneumonia and viral pneumonia, and compared the results with those of control subjects. SUBJECT AND METHOD: BAL was performed with fiberoptic bronchoscopy in patients with M. pneumoniae pneumonia( n=9 ), viral pneumonia( n=9 ), and control subjects( n=6 ) aged 3 years to 9 years. M. pneumoniae pneumonia was documented by polymerase chain reaction and serologic analysis. Four respiratory viruses ( adenovirus, influenza A, influenza B, parainfluenza ) were detected by culture method. Cell pellets and supernatants were separated by centrifugation and Interleukin( IL ) - 2, Interferon( IFN )-r, IL-4, and IL-5 levels were measured in concentrated BAL supernatants by ELISA. RESULTS: Analysis of cytokines revealed significantly increased production of IL-4 ( p< 0.0001 ) and IL-2 ( p< 0.0001 ), in patients with M. pneumoniae pneumonia and significantly increased production of IL-2 (p <0.0001) in patients with viral pneumonia compared with those of the control subjects. Ratio of IL-4/IFN-r was significantly increased in patients with M. pneumoniae pneumonia ( p< 0.005 ) but not in patients with viral pneumonia compared with that of the control subjects. CONCLUSION: IL-4 production and IL-4/IFN-r ratio were increased in the BAL fluid of patients with M. pneumoniae infection. These findings suggest that predominant Th2 immune response could play an important role in the pathogenesis of M. pneumoniae infection.

BACKGROUND: Immunostaining to identify nuclear antigen provides a convenient way of assessing proliferative kinetics in hyperplastic/tumor tissue. OBJECTIVE: The object of this study is to find out whether there are any differences in the expression of proliferation related protein among psoriasis, basal cell carcinoma and squamous cell carcinoma by immunohistochemical evaluation on the PCNA (proliferative cell nuclear antigen) and Ki-67. METHODS: The detection of PCNA and Ki-67 were done by,immunohistochemical methods (avidin-biotin immunoperoxidase methods) using respective monoclonal antibodies in the paraffin embeded tissues from psoriasis (17 cases), basal cell carcinomas (15 cases) and squamous cell carcinomas (10 cases). RESULTS: The labelling indices of PCNA were 14.2±4.0% in psoriasis, 10.9±5.5% in basal cell cardinoma and 28.0±7.8% in squamous cell carcinoma, while the labelling indices of Ki-67 were 15.7±3.8% in psoriasis, 11.26.1% in basal cell carcinoma and 30.3±9.4% in squamous cell carcinoma. CONCLUSION: 1. Interpretation of Ki-67 staining was easier than that for PCNA, mainly because cell morphology was better preserved and the distinction between hyperplastic/tumor and nontumor cell was clear. 2. PCNA and Ki-67 counts had strong correlation to each other (r=0.979). 3. Our immunohistochemical results of PCNA and Ki-67 suggested that proliferative activity was more marked in psoriasis than basal cell carcinoma.
