Industrial culture media for cultivation of marine microalgae Nannochloropsis oculata was optimized by using Random Design software. High eicosapentaenoic acid (EPA) content was obtained over 40% of total fatty acid, and high average specific growth rate of 0.32d -1 was obtained in cells grown in the selected Formula 1. Mass cultivation of this species was practiced in indoor open raceway ponds of 6.12 m 2 and 28.02 m 2, and in outdoor open pond of 83.50 m 2 during May and June in 1999. The average area yield of biomass were obtained at 2.77, 1.62 and 2.52 g /m 2?d, and in October, 1.09 g/ m 2?d was obtained in 83.5m 2 outdoor pond, and the harvest algae powder contained 49.50% of protein, 20.30% of total lipid and 3.00% of EPA of dry weight. With high temperature tolerant species during August in 2000, the average area yield of biomass were increased to 5.44?9.96 and 7.66 g/ m 2?d in above ponds, respectively and 2.50% of EPA of dry weight was contained in the powder. It is indicated that the industrialized cultivation of Nannochloropsis oculata rich in EPA is completely doable on practice, and the algal powder was a good raw material as single cell protein and development of EPA rich products.

According to the project of personnel cultivation in 21st century,we have increased interdisciplinary comprehensive experimental courses to intensify the practical education,optimize operating model and teaching method of experimental courses.Experimental education must be strengthened in order to culture students' creativity.

A monoclonal antibody (McAb) 3H11 against gastric cancer with high positive rate, high selectivity and high affinity was obtained. 131 I Labeled McAb 3H11 was injected into gastric cancer-bearing nude mice, and the tumor/liver ratio, localization index, ID%/g could reach 8.26?1.26, 6.08 + 1.51, 11.00?2.62, respectively. Moreover, McAb 3H11 conjugated with 131 I could increase the cytotoxicity to tumor xenografts and decrease the side effects. The radioimmunoimage was carried out in 19 cases with gastric cancer, and positive image was obtained in 16 cases (84.2%). The radioimmunoguided surgery of gastric cancer was successfully done by submucous injection of labeled McAb 3H11 through endoscope. The sensitivity, specificity and accuracy for evaluation of tumor infiltrated gastric walls were 94.6%, 96.7% and 95.9%, respectively. The sensitivity, specificity and accuracy for identification of metastatic lymph nodes were 99.2% ,97.7% and 98.8%, respectively.
