This study presents the results of an assay concerning: (1) the effect of NaCl induced salt stress in barely plant (cultivar Giza 123) and (2) the possible mitigating effect of silicon in saline conditions. In these study, different concentrations of NaCl (200 & 300 mM) used singly or in combination with silicon (0.5&1.0 mM potassium silicate). Morphological characters of shoot and roots, membrane stability index, relative water content, sodium, potassium, silica, photosynthetic pigments content and some antioxidant enzymes, as well as leaf electron microscope were evaluated. The results showed that, all parameters analyzed decreased except antioxidant enzymes and sodium content were drastically increased by increased salt levels. The supply of silicon (1mM) has successfully mitigated the effect of salinity at 300 mM NaCl. In conclusion, we affirmed that, salt stress is harmful for cape barley plants and the addition of silicon showed effective in mitigating the saline effects.}, keywords = {Hordeum vulgare L,salt stress,silicon,physiological and ultrastructure characters}, url = {https://absb.journals.ekb.eg/article_33754.html}, eprint = {https://absb.journals.ekb.eg/article_33754_9b5c7c9df6545194807423cda06049df.pdf} } @article { author = {Amin, Mohamed}, title = {COMPARATIVE STUDIES ON GROWTH, METABOLISM AND YIELD OF SESAME PLANT BY USING SEAWEED, PLANT EXTRACTS AND SOME GROWTH REGULATORS}, journal = {Al-Azhar Bulletin of Science}, volume = {29}, number = {Issue 1-C}, pages = {19-28}, year = {2018}, publisher = {Al-Azhar University, Faculty of Science (Boys)}, issn = {1110-2535}, eissn = {2636-3305}, doi = {10.21608/absb.2018.33755}, abstract = {A field experiments were carried out in season of 2016/2017 at Botanical garden, Botany and Microbiology Department, Faculty of Science, Al- Azhar University, Nasr City, Cairo, to study the role of bio stimulant (seaweed and plant leaves extracts as a liquid fertilizer) and some growth regulators (indole acetic acid and benzyl adenine) as comparative studies to select the better for improving the growth, biochemical constituents and yield of sesame plants.

Aim of work: This work aimed to study the effect of MSC.s alone and/or in combination with vitamin D3in Streptozotocin (STZ)- induced diabetic male albino rats to detect its potential therapeutic effect and its possible application to humans. Material and methods: Twenty-four male albino rats (150 – 170 grams) were included in this study.

Diabetes was induced by intraperitoneal injection of STZ (50 mg/kg); MSC.s were injected intravenously into the rat tail vein in group III and group IV then left for sixweeks; vitamin D (cholecalciferol) was administered orally at 150 ng (500 IU/kg) each other day at three times per week for a long 6 weeks.Blood glucose leveland body weight were measured weekly for all groups at the beginning of the study at the intervalsixweeks.
