Newly generated plant tissue is inherently sensitive to infection. Yet, when pea (Pisum sativum) roots are inoculated with the pea pathogen, Nectria haematococca, most newly generated root tips remain uninfected even though most roots develop lesions just behind the tip in the region of elongation. The resistance mechanism is unknown but is correlated spatially with the presence of border cells...

Analyzing the pattern and causes of phenotypic and genetic variation within and among populations might help to understand life history variability in plants, and to predict their responses to changing environmental conditions. Here we compare phenotypic variation and genetic diversity of the widespread herb Plantago coronopus across Europe, and evaluate their relationship with environmental an...

The effect of the time of collection on the phenolic content of the flowers of Oenothera speciosa Nutt., cultivated in Egypt, was studied. Samples collected at the early (March) and late (July) flowering periods were analyzed. Flavonoids (expressed as aglycones) and phenol acids were determined by HPLC in the hydrolyzed extracts. Samples gathered in March showed a relatively high percentage of ...

Background & Aims: The topical anesthetic effects of diphenhydramine combined with ingredients such as aluminum and magnesium hydroxide have been used for many years in modern medicine. Due to the limited durability of anesthetic mouthwashes due to saliva secretion and the spreading use of herbal and natural medicines in pharmacotherapy, this study was designed to formulate diphenhydramine in t...

background the dilution and rapid elimination of topically applied drugs due to the flushing action of saliva is a major difficulty in the effort to eradicate infections of oral cavity. utilization a proper delivery system for incorporation of drugs has a major impact on drug delivery and such a system should be formulated for prolonged drug retention in oral cavity. objectives the aim of the p...

Background & Aim: Ocimum basilicum L. is belong to the Lamiaceae family which is cultivated as a culinary, industrial and medicinal plants in some countries from thousands years ago. The seed of this plant is rich in poly un-saturated fatty acids (PUFA) and produced a large amount of mucilage. Experimental: The oil of seed was extracted separately and converted to fatty acids...
