RESUMEN

<p><b>OBJECTIVE</b>To explore the effect of the drug-resistant attenuated Bacillus proteus on the protein expression of CD80 and CD86 in peripheral blood dendritic cells (DCs) of hepatitis B patients.</p><p><b>METHOD</b>Peripheral blood monocytes were isolated from HBV-infected patients and the DCs were separated and induced to differentiate in vitro. The expression of CD80 and CD86 proteins on cultured DCs were examined using flow cytometry.</p><p><b>RESULTS</b>The expression rate of CD80 and CD86 of chronic hepatitis B patients increased significantly (P=0.000), while the positive expression rate of CD80 and CD86 showed no obvious variation in healthy individuals (P=0.185 and P=0.118, respectively).</p><p><b>CONCLUSIONS</b>Bacillus proteus can significantly increase CD80- and CD86-positive cell percentage in peripheral blood DCs of HBV-infected patients, but has no such an effect in healthy individuals.</p>

RESUMEN

<p><b>OBJECTIVES</b>To investigate possible abnormalities of the sperm neck in eight infertile painters observed by transmission electron microscope.</p><p><b>METHODS</b>Spermatozoa from 8 infertile painters (21-32 years old) were observed by transmission electron microscope.</p><p><b>RESULTS</b>The abnormalities of the connecting piece could be divided into 6 types, among which the anomaly of the connecting piece concomitant with a true nuclemalamic condition was the most serious.</p><p><b>CONCLUSIONS</b>The abnormalities may be related to expression obstacles of nuclear genome and mitochondrial genome, and to anomalous cellular signal transduction during spermiogenesis as well.</p>
