An improved system for screening a multiple of candidate therapeutic or chemotherapeutic agents for efficacy as to a specific patient, in which a tissue sample from the patient is harvested, cultured and separately exposed to a plurality of treatments and / or therapeutic agents for the purpose of objectively identifying the best treatment or agent for the particular patient. Specific method innovations such as tissue sample preparation techniques render this method practically as well as theoretically useful. One particularly important tissue sample preparation technique is the initial preparation of cohesive multicellular particulates of the tissue sample, rather than enzymatically dissociated cell suspensions or preparations, for initial tissue culture monolayer preparation. With respect to the culturing of malignant cells, for example, it is believed (without any intention of being bound by the theory) that by maintaining the malignant cells within a multicellular particulate of the originating tissue, growth of the malignant cells themselves is facilitated versus the overgrowth of fibroblasts or other cells which tends to occur when suspended tumor cells are grown in culture. Practical monolayers of cells may thus be formed to enable meaningful screening of a plurality of treatments and / or agents. Growth of cells is monitored to ascertain the time to initiate the assay and to determine the growth rate of the cultured cells; sequence and timing of drug addition is also monitored and optimized. By subjecting uniform samples of cells to a wide variety of active agents (and concentrations thereof), the most promising agent and concentration for treatment of a particular patient can be determined. For assays concerning cancer treatment, a two-stage evaluation is contemplated in which both acute cytotoxic and longer term inhibitory effect of a given anti-cancer agent are investigated.

The present invention is used for evaluating the advantages of haliotis discus hannai. A multi-phase HPLC purification system is used to purify anti-inflammatory peptide from abalone (AAIP, abalone anti-inflammatory peptide). In tandem MS analysis, a fragmentation result shows that the amino acid sequence of the AAIP with nitrogen monoxide (NO) inhibitory activity (IC50=55.8[um]M) is Pro-Phe-Asn-Glu-Gly-Thr-Phe-Ala-Ser (1175.2Da). While the anti-inflammatory effect of RAW264.7 macrophages generated by the stimulus of the AAIP to lipopolysaccharides (LPS) is further studied, and the molecular mechanism is elaborated. The result shows that the AAIP peptide inhibits the nitrogen monoxide (NO) generation induced by the LPS through the expression of inducible nitric oxide synthase (iNOS) by a dose-dependent manner, and the gene transcription of pro-inflammatory cytokines is also obviously reduced, wherein the pro-inflammatory cytokines comprise such as interleukin (IL-1 beta), tumor necrosis factors (TNF-beta) and IL-6. In addition, the AAIP obviously inhibits phosphorylation of mitogen-activated protein kinases (MAPK), such as p-p38 and p-JNK. These results indicate that the AAIP inhibits inflammatory response induced by LPS by intercepting the MAPK pathway of the macrophages. Therefore, the AAIP can be applied to therapeutic drugs for inflammations treatment or healthcare food products.
