Journal of China Medical University.2001;30(2):127-129.

Objective: Our aim was to evaluate effects of magnesium sulfate(MgSO4) on pulmonary hypertension in patients with chronic pulmonary heart disease(CPHD). Methods: Eight patients with CPHD undergone right-heart catheterization. The parameters of hemodynamics and arterial blood gases in patients were measured before and after MgSO4 intravenous infusion(2% MgSO4,40 mg/min). Results: Mean pulmonary artery pressure(mPAP), pulmonary vascular resistance(PVR),mean systemic artery pressure(mSAP), and total systemic vascular resistance(TSVR) significantly decreased(P＜0.05) at 30 minutes after MgSO4 infusion. The decreased percentage of mPAP and PVR at 60 minute after MgSO4 infusion was 13.37% and 18.70% respectively(P＜0.05), but mSAP and TPVR decreased only by 8.15% and 7.43% respectively. The decreased degree of mPAP and PVR at 60 minutes after MgSO4 infusion significantly correlated with mPAP(r=0.712, P＜0.05)and PVR(r=0.802, P＜0.01) before MgSO4 infusion. No unfavorable effect of MgSO4 on other parameters of hemodynamics and arterial blood gases was found. Conclusion: Magnesium sulfate can attenuate pulmonary hypertension in patients with CPHD but may cause transient systemic hypotension.

Xiaoning WANG ; Fang WEN ; Yang ZHENG

Journal of China Medical University.2001;30(2):119-121.

Objective: Our aim was to study the relationship between nitric oxide and ovarian neoplasm. The concentrationg of nitrite /nitrate (NO-2/NO-3),glutathione(GSH), and the activity of superoxide dismutase(SOD) were detected in ovarian tissues.Methods:A modified copper-coated cadium reduction method was used to detect NO-2/NO-3. Dithio-bis-nitrobenzoic acid (DTNB) method was used to detect the GSH concentration. The activity of SOD was measured by an ultramicroanalytic and rapid assay. All the data were obtained from 21 patients with ovarian neoplasm(10 with benign ovarian neoplasms,and 11 with ovarian carcinomas). This paper is concerned with the analysis of matched case-control studies. The carcinoma tissues and normal ovarian tissues were obtained from the same patient. We performed Paired-Samples t test to determine whether the NO-2/NO-3,GSH and the activity of SOD in carcinomas and normal ovarian tissues have significantly difference. Results:No significant difference for the concentration of NO-2/NO-3,GSH and activity of SOD was shown in the normal ovarian tissues and neoplasm tissues of benign neoplasm . The concentrations of GSH and activity of SOD in normal ovarian tissues were significantly higher than ovarian carcinomas(P<0.05). No significant difference of concentration of NO-2/NO-3 was shown in normal ovary and ovarian carcinomas. In the normal tissues of all patients, NO-2/NO-3 was positively correlated with GSH and SOD. Glutathione was positively correlated with SOD. In the ovarian neoplasms, there was no significant correlation between NO-2/NO-3 and GSH, NO-2/NO-3 and SOD,GSH and SOD.Conclusion: Nitric oxide and the other matters which attend the course of its metastasis may closely related to ovary neoplasms.
