METHODS: The mice were divided into 5 groups at random after inoculated with H22 hepatoma into their right axillas hypodermic by intraperitoneal injection(ip) and intravenous injection(iv), and then injected with normal saline,cyclophosphamide and different dosage of ASAC, observe the rate of tumor strain becoming tumor, the inhibition effects of the subjects and the effects of the subjects on mice's viscera. RESULTS: Compared with ip,either high, moderate or low dosage of ASAC by iv did have an obvious inhibitory effect on tumor and the tumor inhibition rates were 46.59%, 46.31% and 32.48% respectively; however, the spleen index in groups that of lower dosage of ASAC by two forms of drug administration were increased; there were death by poisoning in the group that iv with high dosage of ASAC.CONCLUSION: Compared with ip, the administration of ASAC by iv has a better effect on tumor.

Objective To investigate the type of plasmid map of Y. pestis in the R. opimas natural plague loci in Junggar Basin. Methods A total of 39 plasmid DNA of Y. pestis which were isolated from the natural plague loci of Junggar Basin, Tianshan Mountain, Kunlun Mountain, Qinghai-Tibet Plateau and In-ner Mongolia were extracted by the methods of Kado and Liu. The plasmid map was analyzed by the methods of agarose gel eleetrophoretogram. Results Two types of plasmid map were found in 26 Y. pestis which were isolated from Junggar Basin. Of them 23 were 6 × 106, 45 × 106 and 65 × 106 type of plasmid map, and 3 were 6 × 106, 45 × 106 and 72 × 106 type. Conclusion There are two types of plasmid map in the R. opi-mus natural plague loci in Junggar Basin. One type, which is the dominant type in this area, is 6 × 106, 45 × 106 and 65 × 106 type. This type is also similar to the dominant plasmid map type of the nature plague loci of Tianshan Mountain, Kunlun Mountain, Qinghai-Tibet Plateau and Inner Mongolia. The other type is 6 × 106, 45 × 106 and 72 × 106 type, and this type is new plasmid map type of Y. pestis in our country.

BACKGROUND: Type Ⅰ collagen is a specific collagen secreted by in vitro cultured osteoblast, and the formed network is the basis of bone mineralization, which also reflects the ability of osteoblast bone formation. Studies have shown astragalus root increased osteoblast proliferation. However, the effect of astragalus root on improving type Ⅰ collagen expression of osteoblast remains poorly understood.OBJECTIVE: To evaluate the effect of astragalus root injection on the abilities of rat cranium-derived osteoblast proliferation and type Ⅰ collagen expression.METHODS: Rat osteoblast was cultured in vitro and divided into control group (MEM culture solution containing calf serum) and astragalus root groups (different concentrations). The effect on osteoblast proliferation was evaluated on days 1, 3, 5, 7, and 9 by MTT method. Moreover, the expression of type Ⅰ collagen protein was observed after 6 hours of treatment with astragalus root injection using in cell western-blot method. In addition, the gene expression of COLLal was investigated by real-time PCR method.RESULTS AND CONCLUSION: From days 3 to 9, the different concentrations of astragalus root injection improved osteoblast proliferation, respectively compared with control group (P ＜ 0.05), and this ascending trend peaked on day 7. Different concentretions of astragalus root injection improved COLLol mRNA expression, especially 15% astragalus root injection was the most effective. The type Ⅰ collagen protein expression of 15% and 10% astragalus root injection were significantly greater compared with the control group (P ＜ 0.05). Astragalus root injection improved in vitro cultured osteoblast proliferation and type Ⅰ collagen secretion in a certain dose-effect manner.
