Antibacterial activity of different Egyptian honeys in relation to some bee products

The antibacterial activities of different types of honey in relation to some bee products were investigated against 5 species of pathogenic bacteria belonging to Gram positive and Gram negative bacteria. The honey types were Citrus, Cotton Sesame and Clover. The bee products were royal jelly and bee venom. The bacteria were Staphylococcus aureus. Streptococcus faecalis, Corynebacteria pseudotuberculosis, Pseudomonas aeruginosa and E.coli The influence of the storage was studied in case of clover honey from season of 1965 and 1995. Honey was used in different concentration. The results revealed that the different Egyptian honey, royal jelly and bee venom were effective antibacterial against different pathogenic bacteria. It was clear that the different types of honey as well royal jelly and bee venom were less effective against E. coli than other bacteria

Effect of EGF on the transfer and uptake of nutrients in the human placenta

The aim of the present study is to investigate the effect of epidermal growth factor [EGF] on the transport and metabolism of glucose and amino acids in the human placenta perfused in vitro. There was no significant difference in glucose transfer between control phase and the EGF phase. The fetal lactate release significantly increased after 35 minutes of the addition of 66 mg/ml of EGF then it returned to the normal level. The transfer and uptake of alpha-amino isobutyric acid [AIB] was not modified by EGF addition. On the other hand, the uptake of antipyrine significantly decreased after the EGF administration. 66 and 100 mg/ml of EGF induced highly significant decrease in the maternal glucose uptake. There is non-significant increase in fetal lactate release and a nonsignificant decrease in the maternal lactate release.10 mg/ml of EGF caused non-significant increase and 66 and 100 mg/ml of EGF caused non-significant decrease
