【摘要】： 新型降糖活性物質(zhì)的研究: 治療糖尿病包括以下兩種方式:1,使用胰島素;2,使用其他降糖藥物。對應(yīng)這兩種方式,本文構(gòu)建和篩選了兩種降糖活性物質(zhì),并分別對這兩種物質(zhì)的降糖效果進行了研究。對于CTB-人胰島素融合蛋白,構(gòu)建并篩選到含CTB-BA的陽性細胞并采用了Balb/c小鼠動物試驗檢測其降血糖活性,表明陽性細胞具有較強的降血糖活性。對于普洱茶,首先對各種茶在體外對PTP-1B的抑制作用進行了考察,并得到對PTP-1B抑制作用最強的普洱茶。對普洱茶在db/db小鼠上的降糖效果進行研究。普洱茶水飲用組表現(xiàn)出很高的降血糖活性,而采用灌胃給藥組亦表現(xiàn)出一定的降糖活性。對普洱茶的減肥作用進行研究,飲用普洱茶具有減肥作用。對普洱茶對糖尿病患者和健康受試者的降血糖作用進行了研究,發(fā)現(xiàn)對于糖尿病受試者組,普洱茶顯著地降低了他們的空腹血糖、餐后2h血糖和HbA1c(%),健康受試者組則沒有明顯的變化。對試驗前后血Ca~(2+),K~+濃度進行檢測,實驗前后血Ca~(2+),K~+的濃度均在正常范圍內(nèi),證明喝茶不會造成Ca~(2+),K~+流失。新型脂質(zhì)體疫苗的研究: 以脂質(zhì)體作為流感裂解疫苗佐劑,采用凍干重建法,制備了流感脂質(zhì)體疫苗。實驗表明,相同劑量下,脂質(zhì)體流感疫苗組與相應(yīng)非脂質(zhì)體流感疫苗組相比,可激發(fā)2-4倍的抗體,抗體高峰持續(xù)時間更長,在脾細胞增值比率,CD4+水平及CD4+/CD8+比例,以及細胞因子(IL-4、IFNγ)水平上均有顯著的增強作用。脂質(zhì)體流感疫苗不但能夠刺激機體產(chǎn)生較無佐劑疫苗更高效持久的體液免疫,而且能夠激發(fā)機體產(chǎn)生細胞免疫。
[Abstract]:Studies on novel hypoglycemic active substances:. There are two ways to treat diabetes: 1: 1, insulin 2, and other hypoglycemic drugs. For these two methods, we constructed and screened two hypoglycemic active substances. For CTB- human insulin fusion protein, positive cells containing CTB-BA were constructed and screened, and the hypoglycemic activity of CTB- human insulin fusion protein was detected by Balb/c mice test. The results showed that the positive cells had strong hypoglycemic activity. For Pu'er tea, the inhibitory effects of various kinds of tea on PTP-1B in vitro were investigated. Pu'er tea, which has the strongest inhibitory effect on PTP-1B, was obtained. The hypoglycemic effect of Pu'er tea on db/db mice was studied. The drinking group of Pu'er tea water showed high hypoglycemic activity. The effect of drinking Pu'er tea on reducing blood sugar was studied, and the hypoglycemic effect of Pu'er tea on diabetic patients and healthy subjects was studied. It was found that in diabetic subjects, Pu'er tea significantly decreased their fasting blood glucose, 2 h postprandial blood glucose and HbA1cU, but not in healthy subjects. Before and after the experiment, the concentration of blood Ca~(2 was in the normal range, which proved that drinking tea would not cause the loss of Ca~(2. Study on novel Liposome Vaccine:. Using liposome as adjuvant of influenza lytic vaccine, the influenza liposome vaccine was prepared by freeze-dried reconstruction method. The experiment showed that the liposome influenza vaccine group was compared with the corresponding non-liposome influenza vaccine group at the same dosage. The antibody can be stimulated 2-4 times, the antibody peak duration is longer, in splenocyte proliferation ratio, CD4 level and CD4 / CD8 ratio, The liposome influenza vaccine can not only stimulate the body to produce more efficient and lasting humoral immunity than the adjuvant vaccine, but also stimulate the body to produce cellular immunity.
