ABSTRACT
<p><b>OBJECTIVE</b>To investigate the value of Tei index and the sensitivity of left versus right ventricular Tei index in evaluating the fetal cardiac function in pregnancy-induced hypertension syndrome in the third trimester.</p><p><b>METHODS</b>Fetal echocardiograms were performed in 30 women with pregnancy-induced hypertension (PIH) syndrome and 55 with normal pregnancy of the third trimester. Tei index was obtained by calculating the ratio of the isovolumic time (isovolumic contraction and relaxation time) to the ejection time of the left and right ventricle. Comparisons of the Tei index were made between the PIH group and control group, and also between the left and right ventricles in each group.</p><p><b>RESULTS</b>Significant difference was found in the left and right ventricular Tei index between PIH group and control group. No difference was noted between the left and right ventricular Tei index in the PIH group.</p><p><b>CONCLUSIONS</b>Tei index is a useful indicator in evaluating fetal global cardiac function, for which purpose the left ventricular Tei index can be as sensitive as the right ventricular Tei index.</p>

Effects of 7 fungus strains on tobacco quality by applying fungal leavens on upper leaves were studied. Results showed that BF03, BF06 and BF63 can remarkably change the chemical components of tobacco, such as soluble sugar, protein, nicotine etc., and make them more harmonious. And the smoking quality of the flue-cured tobacco leaves treated was much better than the control.
