ABSTRACT
Objective To study the influence on the tumor after percutaneous intra-tumor injection of ~(32)P-GMS in liver cancer as well as its suitable dose.Methods 24 New Zealand rabbits were used to establish the animal model of VX-2 liver cancer,and divided into A,B,C and D groups with individually 37,74,111 and 148 MBq of ~(32)P-GMS being injected,respectively;and then pathological changes of tumor were observed by light and electron microscope respectively.Result The dose of ~(32)P-GMS was obviously correlated with the radioactivity damage of tumor cells.In the A and B groups,the tumor cells were not observed to disappear completely after injection of ~(32)P-GMS,but in C group,tumor cells were almost completely disappeared and surrounded by a lot of connective tissue.Although the tumor cells were found to disappear completely in D group,normal liver tissues were also involved.Conclusion Percutaneous intra-tumor injection of ~(32)P-GMS with suitable dose that may induce the tumor tissue to be maximally damaged and may also provide some significances to prevent the tumor metastasis.
ABSTRACT
Object: To observe the effect of PGMS on lipids metabolic disturbance in diabetes mellitus. Methods: 50 cases (male 18,female 32,average age 58?6 years old ) with lipids metabolic disturbance in diabetes mellitus were given PGMS. Each of them took 100mg/time,3 times/day for 60 days, meanwhile kept on taking diabetes mellitus diet and anti-diabetic medicine. Detected and compared the amounts of TC, TG, HDL, Glucose of blood, and Glucose of urine before and after PGMS were given. Result: TC and TG were decreased obviously (P
ABSTRACT
The abnormal proliferation of vascular smooth muscle cells after endothe-lial injury is postulated to be the main pathophysiological process in atherosclerosis (AS). The effects of propylene glycol mannate sulfate(PGMS) on the proliferation of bovine cerebral microvessel smooth muscle cslls (BCMSMCs) induced by 10% fetal calf serum (FCS) and interleukin l(IL-1) were investigated in culture. 5 - 8 stage subcultured BCMSMCs were incubated into 96-well dish- With either 10% FCS or IL-1 (50u/ml) to produce BCMSMCs proliferation , the inhibitory effects of PGMS on proliferation of BCMSMCs were investigated. The results shows that PGMS could inhibit the proliferation of quiescent BCMSMCs induced by 10% PCS. The growth of cells was inhibited, comparing with normal control 72hours after the serum addition as determined by crystal violet stainning and MTTmethod. The proliferation of quiescent BCMSMCs induced by IL-1 (50u/ml) was also inhibited by PGMS as determined by crystal violet stainning and MTT method. The results suggested that PGMS inhibit the proliferation of BCMSMCs induced by 10% FCS and IL-1 ,and the use of PGMS may probably play an important role in the treatment of cerebrovascular disease.
ABSTRACT
We analysed the therapeutic effect and laboratory findings in the patients of a-cute cerebral infarction treated with PGMS and PSS. The results show that the efficient rate of PGMS group was obtained to 95. 6% and 70. l%,and was better than that of PSS group, but there was no statistic significance. The laboratory findings show the i both of them had the effect of anticogau ant and decreasing blood viscosity and serum co tents of lipids. But PGMS had a slight anticoagulant effect and could obviously decrease olood viscosity and serum contents of lipids. here was no side effects in the PGMS group. So PGMS is considered to be a prospective drug for treating acute cerebral infarction.
ABSTRACT
The effects of Proplylene glucol mannurate sulfate (PGMS) on mice's immunological function have been studied with immunological techniques. When given orally,PGMS could enhance the weight of the mice's immunological organs and the speed of carbonparticle elimination in mice,the phagocytic rate and index of the macrophagocytes in the mice's abdominal cavity were enhanced, the percentage of ANAE" lymphocytes were increased, the production of hemolysin in mice peripheral blood were promoted. The study suggests that PGMS improves both the specific and nonspecific immunological function in mice.
ABSTRACT
The therapeutic effect and laboratory findings in 137 case of acute cerebral infarction treated with Propylene Glycol Mannurate Sulfate (PGMS) were analysed. The positive therapeutic response to PGMS in the treated group was obtained to 95. 6% and 70. 1%,and was better than that of the controls ( P
ABSTRACT
The influences of propylene glycol mannate sulfate (PGMS) on experimental thrombosis and thrombolysis in vivo were studies after iv 8. 125, 6. 25, 12. 5 , 25mg/Kg in rabbits, and the effect of antithrombosis of PGMS was compared with that of heparin. The results showed that PGMS possessed remarkable effect of antithrombosis. In order to explore the mechanism of antithrombosis of PGMS, we studied the influences on the fibrinolytic and coagulant function of rabbits. The results showed that PGMS can pronouncedly prolong the prothrombin time (PT), thrombin time (TT), kaolin partial thromboplastin time (KPTT), and enhance the activity of antithrombin-III (AT -III). PGMS can cause a remarkable increase in fibrin degradation product (FDP) , shorten euglobulin lysis time (ELT) , and a decrease in the contents of fibrinogen and plasminogen activity. These results suggested that PGMS probably exert the antithrombotic effect by inhibiting coagulation and activating fibrinolysis.
ABSTRACT
To explore the mechanism of protecting erythrocyte deformability (ED) of polysaccharide sulfate(PSS)and propyllene glycolmannurate sulfate(PGMS) in patients with acute myocardial infarction (AMI). The erythrocyte filtration index(EFI),erythrocgte membrane Na+,K+-ATPase .glutathione peroxidase(GSH-Px)activity and lipid peroxide(LPO) were measured in 52 patients with AMI. Meanwhile the effects of PSS and PGMS on EFI, Na+,K+-ATPase ,GSH-Px and LPO in AMI patients were observed in vitro. The results showed that the EFI and LPO were markedly higher ,Na+ ,K+-ATP ase and GSH-Px were si-hnificantly lower in patients than those in control(P0. 05). These results indicate that PSS and PGMS could improve the ED in patients ,and the efficacy of PSS or PGMS was related to enchancement of erythrocyte membrane ATP-ase anci GSH-Px activity.
ABSTRACT
The changes of leucocyte deformability (LD) and effects of PGMS and PSS on LD in patients with acute cerebral infarction (ACT) were observed. The results showed that leucocyte filtration index (IF) was higher significantly in patients with ACI than that in the normal control ( P
ABSTRACT
The present study on 24 cases disclosed that the erythrocyte deformability(ED) of patients with acute myocardial infarction (AMI) was significantly lower than normal control. After incubate the patients' erythrocyte with Prop-lene Glycol Mannituse Sulfate(PGMS) and Pro-plene Glycol Alginate Sudium Sulfate (PSS ) , The ED was significantly higher than that of in-cubated without drug. PGMS was more effi-cious. The result indicated that PGMS and PSS may have high value in improving the microcir-culation of patient with AMI, increasing the blood flow of capilliaries in ischemic myocardium and reducing the area of infarction.
