Plasmid vectors with either RSV or CMV promoter are frequently used for DNA- mediated immunization due to the availability in commercial. Consequently, influence of the vector constituents, such as promoter, enhancer and transcription termination signal etc. on vaccination efficiency is not studied extensively. As an initial attempt to develop an efficient vector system for DNA-rnediated immunization, influence of promoter for antigen gene expression on vaccination efficiency has been analyzed. Initially, plasmids with either B-actin or muscle creatine kinase (MCK) promoter were constructed from the plasmid with prototype CMV promoter. In addition, ovalbumin (OVA) antigen gene has been cloned into each vectors to generate the plasmid vectors with different promoters for induction of the anti-OVA immune responses. Antigen protein expression in antigen gene transfected mouse muscle myoblast cells showed that the level from MCK promoter containing plasmid was slightly higher than those from either CMV or B-actin promoter containing plasmids. Also, the same plasmid turned out to be slightly more efficient than other plasmids in antibody imrnune response induction in vivo, when they were applied both through intramuscularly and intradermally. These results suggest that the commonly used CMV promoter containing plasmid vector could be further modified to develop an efficient vector for DNA-mediated immunization.

We report a 44-year-old female patient with Eosinophilic cellulitis who had developed pruritic erythematous plaque on the right lower abdomen since two months ago. The blood eosinophil count was 2,066/mm at first visit. This lesion responded well to cortieosteroid therapy. However new erythematous swelling reappeared on the left lower abdomen and left inner thigh 3 months after the first treatment. A biopsy specimen taken from an erythematous plaque showed many flame figures and diffuse infiltration of eosinophils and histiocytes in the lower dermis and subcutaneous fat tissue.

Objective To evaluate the significance of fiberoptic bronchoscopic brush cytology in the diagnosis and histological classification of lung carcinoma.Methods Data of 309 patients with lung carcinoma were retrospectively analyzed.Both bronchoscopic cytology and histology diagnosis were available.The positive rate of bronchoscopic cytology and tissue biopsy were calculated respectively.The classification accuracy of cytological diagnosis for lung carcinoma was evaluated.In tissue biopsy standard,evaluated the significance of bronchoscopic cytology in diagnosis and histological diagnosis.Results The positive rate of bronchoscopic cytology and tissue biopsy were 86.1％ (266/309) and 83.8％ (259/309),respectively.Bronchoscopic cytology combined with bronchial biopsy could obviously improve the positive rate to 94.2％ (291/309) in lung carcinoma diagnosis.Taking the tissue biopsy histological type as a standard,the cytotyping accuracy for brush method was 85.1％(74/87) in squamous carcinoma,82.4％(108/131) in adenocarcinoma and 100％(11/11) in small cell carcinoma for higher.However,the accuracy in diagnosing poorly differentiated carcinomas was only 12.2％ (5/ 41).Conclusion Fiberoptic bronchoscopic brush cytology plays an stable and important role in diagnosing lung carcinomas and histological type determination.However,it has limited use in diagnosing poorly differentiated carcinomas.
