Antioxidant properties and prevention of cell cytotoxicity of Phlomis persica Boiss

The free radical scavenging capacity, reducing power and inhibition of beta-carotene peroxidation of Phlomis persica [PP] extracts was investigated. In addition, the effect of this extract on reduction of the hydrogen peroxide-induced cytotoxicity in non-immortalized fibroblast was examined. The extracts showed free radical scavenging capacity, and the ethyl acetate extract showed marked effect on inhibition of lipid peroxidation similar to that of gallic acid. These results were further supported by a protective effect of Phlomis crude extract on H[2]O[2]-induced cytotoxicity in human non-immortalized fibroblasts

Comparison of the recombinant glucosephosphate isomerase from different zymodemes of entamoeba histolytica with their natural counterparts by isoenzyme electrophoresis

Entamoeba histolytica is the etiological agent of invasive amoebiasis, the third leading parasitic cause of mortality in the world. Our aim was to find a molecular correlation between a glucosephosphate isomerase zymodeme analyses in E. histolytica zymodemes. It was demonstrated that natural and recombinant glucosephosphate isomerase enzymes of E. histolytica comigrated in the starch gel electrophoresis, indicating that the isoenzyme pattern of E. histolytica glucosephosphate isomerase could be explained from the primary sequences alone and means that expression of the polypeptides of the described sequences in Escherichia coli are able to reproduce the classical glucosephosphate isomerase isoenzyme patterns

Etude des variations du taux d'oestroil serique dans divers cas au cours de la gestation chez des femmes iraniennes

The total serum oestriol was measured among the Iranian women after the 25 th. week of pregnancy. From the total of 233 women examined 198 had normal pregnancies and the other 35 were high risk pregnancies and were under medical servillence. From the 25 th. week of gestation the serum oestriol among the normal subjects ranged from 64.8 +/- 12.4 ng/ml to the highest level of 205.0 +/- 57.3 ng/ml correlations were observed between the weights of the new born babies and the serum oestriol level during the pregnancies. In most cases among the high risk pregnancies the total serum oestriol showed a notable variations
