Introduction: It has been reported that garlic (Allium sativum) and onion (Allium cepa) are used all over the world in different diseases, such as infections, injuries, gastrointestinal dysfunctions and cardiovascular diseases. Therefore, our aim in this work was to study the ability of garlic and onion oils to offset the infectivity as well as the metabolic disturbances induced by Schistosoma ...

The problem of the localization of intranucleolar DNA in root meristematic cells of Allium cepa has been investigated under both light and electron microscopy following formaldehyde fixation coupled with deoxyribonuclease extraction. The observations reveal that most, if not all, of the intranucleolar DNA is located inside small lacunar spaces confined to the fibrillar regions of the nucleolar ...

We evaluated the antiproliferative effect of infusions from Pluchea sagittalis using the Allium cepa test. Infusions in three concentrations (2.5, 5, and 25 g dm-3) of leaves cultivated in three environments (in vitro, acclimatized growth chamber, and field) were used. Six onion bulbs were used for each of the eight treatments, and the mitotic index was obtained from 6000 cells per treatment. I...

The Purpose of the study was the isolation and identification of Urinary tract infection (UTI) bacteria and the evaluation of their susceptibility against antibiotics. In addition, susceptibility and chemotactic behavior of isolated strains were evaluated against medicinal herbal plant extracts. To perform the study, 200 samples were collected from the patients suffering from UTI. Then, the bac...
