RESUMO

<p><b>OBJECTIVE</b>To observe the clinical effect of Xuefu Zhuyu Capsule (XFZYC) in treating unstable angina pectoris (UAP) and to investigate its mechanism of protection on vascular endothelia.</p><p><b>METHODS</b>Sixty UAP patients were randomly assigned to two groups, the 30 in the treated group were treated by conventional therapy plus XFZYC, and the 30 in the control group treated by conventional therapy alone. The frequency and persistent time of angina pectois, dosage of nitroglycerin used, changes of electrocardiogram (ECG) were observed, and the plasma levels of endothelin (ET), nitric oxide (NO), von Willebrand factor (vWF), soluble vascular cell adhesion molecule-1 (sVCAM-1) and soluble intercellular adhesion molecule-1 (sICAM-1) were tested before and after the two-month therapeutic course.</p><p><b>RESULTS</b>(1) The clinical symptoms as frequency and persistent time of angina pectoris in the treated group were bettered significantly after treatment and the dosage of nitroglycerin used decreased (all P < 0.01), showing significant difference when compared with those in the control group (P < 0.05). (2) The effective rates on UAP symptoms and ECG in the treated group were 86.7% and 76.7% respectively, which were significantly higher than those in the control group (70.0% and 63.3%, P < 0.05). (3) Laboratory examination showed in the control group, changes only displayed in the decrease of vWF and ET and increase of NO (all P < 0.05), while in the treated group, plasma levels of vWF, ET, sVCAM-1 and sICAM-1 after treatment significantly decreased and were lower than those in the control group (P < 0.01), but NO elevated significantly and was higher than that in the control group (P < 0.01).</p><p><b>CONCLUSIONS</b>XFZYC is an effective Chinese patent medicine for treatment of UAP. It displays its effect on protecting vascular endothelia and anti-angina pectoris partially by decreasing the plasma levels of ET, vWF, sVCAM-1 and sICAM-1 and elevating the level of NO.</p>

RESUMO

This paper studied the effect of polyethylene glycol (PEG) on regeneration and free proline accumulation of callus of Pogonatherum paniceum (Lam.) Hack. under motionless liquid culture condition and shake liquid culture condition. Callus of P. paniceum had the ability to resist the stress of PEG. The effects of PEG stress and culture conditions on the callus of P. paniceum appeared mainly in two aspects, delaying regeneration time and debasing regeneration rates. The shake liquid culture mainly delayed the regeneration time and PEG stress mainly debased the regeneration rates. Free proline accumulated in the two culture conditions, and the contents of proline were positively correlated with PEG concentrations and culture time. After stress removal, most of the callus could recover the ability of regeneration, and the free proline might pay an important part in the inhibition and recovery. So it must be chosen a more than 300 g x L(-1) PEG concentration and long than 3 weeks culture time in the selection of drought-resistant mutants of P. paniceum. The motionless liquid culture was more suitable for selection of drought-resistant mutants.

RESUMO

Objective To assss the clinical significance of Cystatin C(Cys C)as a marker of renal function in kidney transplant patients especially when infection or acute rejection occured.Methods Among 65 renal transplant recipients the concentrations of serum Cys C and serum creatinine(Scr)were determined before and one month after the transplantation,and also in the day and next day of occurrence of infection or rejection.Meanwhile,30 healthy persons and 30 infected patients without kidney transplantations were served as control.Results The concentrations of Cys C were nearly equal between healthy persons and the infected patients without kidney transplantations(P = 0.32).The level of serum Cys C and Scr dropped quickly in the first 3 days after transplantation(decreased by 69.2%,74.7%,75.8% for Cys C and 38.4%,74.5%,81.4% for Scr)(P
