  • APPLICATION OF BIOREACTOR IN TISSUE ENGINEERING

    Objective To demonstrate the importance of bioreactor to tissue engineering and to disscuss the direction of bioreactor- researching. Methods Alarge quantity of literature was reviewed, analyzed and summarized. Results Bioreactor has greatly promoted the progress of tissue engineering in heoretics and practice,and has become one of the most important parts of tissue engineering. Conclusion Bioreactor is indispensable for tissue engineering,and it should be developed along integration,automation and intelligentificaton.Its application should run through the whole process of tissue engineering.

  • Cultivation of rabbit iris pigment epithelial cells and observation of its ultrastructure

    Objective To establish a method for primary culture of iris pigment epithelial cells(IPE). MethodsEnzyme-Assisted microdissection was used to isolate and cultivate the IPE cells.An identification was made with microscopic and immunohistochemical observations.Results IPE were successfully sultured and showed on differences with RPE in primary culture and subculture.ConclusionEnzyme-Assisted microdissection is a reliable and quick method for the isolation of IPE.

  • Value of Chemosensitivity Assay In Vitro on Breast Cancer

    Objective To explore the value of chemosensitivity assay in vitro on breast cancer. Methods In vitro chemosensitivity of 6 species of chemotherapeutic agents applied to 38 cases of breast cancer patients were detected by tissue culture-end point staining-computer image analysis (TECIA). Results The sensitivity to chemotherapeutic agents commonly used in the breast cancer level from high to low was as follow: Doxorubicin (ADM), Paclitaxel (TAX), Vinorelbine (NVB), Cyclophosphamide (CTX), Cisplatin (DDP) and Fluorouracil (FU). Conclusion Drugs sensitivity experiment of cancer in vitro by TECIA has an important value to instruct clinical medication and individual chemotherapy for breast cancer.

  • Diagnostic Value of CT-Guided Percutaneous Lung Biopsy in Pulmonary Diseases

    ObjectiveTo evaluate the diagnostic value of computer tomography (CT)-guided percutaneous lung biopsy and tissue culture in pulmonary diseases. MethodsAfter the preoperative evaluation, 48 patients underwent CT-guided percutaneous lung biopsy were analyzed, and 16 patients accepted tissue culture. The clinical significance of combined diagnostic rate of histopathology and tissue culture was investigated. ResultsAll patients were punctured successfully. The pathological diagnosis confirmed 26 (54.2%) cases with malignant lesions and 16 (33.3%) cases with benign lesions. Six cases could not be pathological diagnosed. The pathological diagnostic rate was 87.5%. Sixteen patients accepted tissue culture. Among them 3 cases with benign lesions were cultured. The positive rate of tissue culture was 18.8%, and improved to 30.0% in the patients with benign lesion. The combined diagnostic rate of histopathology and tissue culture was 89.6%. In addition, the accuracy rate of pathological diagnosis in the group of lung nodules was 95.0%, higher than the others. The accuracy rate of pathological diagnosis in lung nodules of 2cm~3cm in diameter was 100.0%, and the positive rate of tissue culture in lung lump of 3cm~5cm in diameter was 25.0%. The incidence of pneumothorax and hemorrhage was 14.6%. ConclusionsCT-guided percutaneous lung biopsy is a safe and effective diagnostic method. For pulmonary infectious diseases, combination of CT-guided percutaneous lung biopsy and tissue culture can improve the early diagnostic rate.
