Objective To setup a measurement of human bone marrow micromegakaryocyte which based on CD41a and PI double‐labeled flow cytometric analysis ,and study the significance in the diagnosis of MDS .Methods In 42 cases of MDS patients , their bone marrow megakaryocytes were obtained by Percoll density gradient separation medium .The megakaryocyte glycoproteinⅡb/Ⅲa(CD41a)were marked with fluorescein isothiocyanate through its corresponding monoclonal antibody ,and their DNA were marked with PI .Then the megakaryocyte ploidy was analyzed by flow cytometry(FCM ) .Results The method for micromegakaryo‐cyte identification and analysis was established .In 42 patients with MDS ,the detection rate of micromegakaryocyte was 90 .5 per‐cent by FCM analysis ,but only 54 .8 percent by Wright‐Giemsa staining test and 64 .3 percent by immunohistochemistry ,the differ‐ence among them was statistically significant(χ2 = 13 .640 ,P= 0 .001) .The 42 patients with MDS were divided into two groups (low‐risk group and high‐risk group) .The detection rates of micromegakaryocyte were 81 .8 percent in low‐risk group and 100 per‐cent in high‐risk group separately by FCM analysis ,the difference was statistically significant(χ2 =4 .019 ,P=0 .045) .Conclusion The detection rate of micromegakaryocyte by FCM with CD41a and PI double marker is higher than that by cytochemical staining . The detection rate of micromegakaryocyte in the high‐risk group is higher than that of the low‐risk group ,which shows that the de‐tection of micromegakaryocyte is of great significance for MDS prognosis assessment .

Objective To investigate the development and dynamic changes of host immune response in DBA/2 mice infected with Plasmodium yoelii 17XL. Methods Female DBA/2 mice were infected by intraperitoneal ( i. p. ) injection of 106 P. yoelii 17XL parasitized erythrocytes ( PRBC). Levels of IL-12, IFN-γ, IL-4, IL-10 and P. yoelii 17XL-specific antibody in sera were measured by ELISA. Concentrations of NO in cell supernatants were measured by the Griess reaction. Parasitemia,percentage of mononuclear-macrophages of individual mice were monitored daily, and phagocytosis of mononuclear macrophages was also observed. Results Primary parasitemia in vein blood was developed on day 3 postinfection, which peaked with a level of 46. 9% on day 9. Most mice cleared the infection and survived by day 20 postinfection. From day 6 to day 16, the phagocytosis of PRBC by rodent macrophages was observed on the blood smear. Infected mice had a continuously increased level of IL-12 in serum from day 1 postinfection. Accordingly, high level of IFN-γ was also detected in sera from day 1 postinfection,which peaked on day 6. Infected mice produced higher level of IL-4 and IL-10 in serum on day 6 postinfection, which peaked on day 9 and day 15 postinfection respectively. In addition, splenocytes from infected mice produced significantly higher level of NO on day 6 and 20 postinfection. Level of P. yoelii 17XL-specific IgG was determined in the sera of infected mice with a steadily increased trend after infection, which peaked on day 70 postinfection. Conclusions Effective polarizing of Thl cells is significant in inhibition of parasitemia and eventual clearance of the Plasmodium parasites. Activated mononuclear-macrophages play a key role in inhibiting parasitemia in the early phase of infection with P. yoelii 17XL.
