Two barley cultivars were subjected to water stress by immersing their root system in PEG 6000. The relative water content (RWC) of the leaves fell under these conditions and membrane disorganisation was evidenced by the injury index data. The two genotypes differed in their leaf water content under the applied stress. The aim of this work was to examine the relationship between proline accumul...

Three diluents were studied, to determine which is the best for the automated immunochemical measurement of specific serum proteins. Nine serum proteins (orosomucoid, a 1-antitrypsin, a2-macroglobulin, haptoglobin, transferrin, C3, lgG, IgA, and 1gM) were measured in physiological saline (9 g NaCI/liter), tris(hydroxymethyl)aminomethane buffer (0.01 mol/liter; pH 7.4), and physiological saline ...

Biodegradable implants of ciprofloxacin hydrochloride for post operative site delivery were prepared using glyceryl monostearate and different concentrations of polyethylene glycol (PEG 6000), glycerol and Tween 80 as erosion enhancers by compression and molding technique. Formulations were subjected to in vitro drug release by the USP dissolution method, while promising formulations were subje...

The in vitro dissolution studies of encapsulated sodium salicylate granules coated with beeswax is presented. The factors investigated were the effects of concentration, presence of a hydrophilic fatty material, polyethylene glycol 6000 (PEG 6000), and technique (pan-coating, fusion and granulation) on the sustained release of drug when coated with beeswax. Comparison of release rates was based...

Benih kakao ( Theobroma cacao L.) merupakan benih rekalsitran yang cepat mengalami kemunduran selama penyimpanan. Penanganan tepat melalui invigorasi, dapat menjadi solusi untuk mempertahankan dan meningkatkan viabilitas vigor. Penelitian bertujuan mengetahui pengaruh invigorasi lama penyimpanan terhadap pertumbuhan awal bibit kakao. Bahan digunakan kakao, cocopeat, PEG 6000, NAA, GA 3 bahan pe...

At the early vegetative growth stage, mungbean are mostly affected by drought, and it is also one of most promising stages that can be used to screen for drought stress tolerance traits in multiple varieties. Therefore, this study utilized polyethylene glycol (PEG-6000) induce towards selection varieties their stage using both hydroponics soil based systems. In study, leaf wilting index respons...

Drought is one of the most important abiotic constraints on agricultural productivity, while global warming leads to occurrence more frequent drought events. Cyclocarya paliurus a multiple-function tree species with medicinal value and timber production, but no information available its tolerance. In this hydroponic experiment, variations in leaf anatomical morphology, chloroplast ultrastructur...

Aqueous two-phase systems (ATPS) have  emerged as a powerful extraction method for the downstream processing of bio-molecules. The aim of this work was to investigate the possibility of utilizing ATPS for the separation of recombinant Bacillus sphaericus phenylalanine dehydrogenase (PheDH). Polyethylene glycol (PEG) and ammonium sulfate systems were selected for our experi...

glibenclamide (glib) is a poorly soluble drug with formulation-dependent bioavailability. therefore, we attempted in this study to improve glib dissolution rate by preparing drug solid dispersions by solvent evaporation (se) and supercritical fluid solvent-antisolvent techniques (scf-sas). a d-optimal mixture design was used to investigate the effects of different ratios of hpmc e5 (50-100%), p...
