1. Permeability to water in unfertilized eggs of the sea urchin, Arbacia punctulata, is found to be greater in hypotonic solutions of dextrose, saccharose and glycocoll than in sea water of the same osmotic pressure. 2. The addition to dextrose solution of small amounts of CaCl(2) or MgCl(2) restores the permeability approximately to the value obtained in sea water. 3. This effect of CaCl(2) an...

Background & Aim: According to the increase in diseases such as diabetes and obesity, using of saccharose alternatives for producing of low-calorie and sugar-free alternatives, are taken into consideration of researchers and industrialists. Among them, steviosidewith the 300 times more sweetness than saccharose has special place, due to is a natural. The aim of this study is op...

Stevia rebaudiana Bertoni, an ancient perennial shrub of South America, produces diterpene glycosides that are low calorie sweeteners, about 300 times sweeter than saccharose. Stevia extracts, besides having therapeutic properties, contain a high level of sweetening compounds, known as steviol glycosides, which are thought to possess antioxidant, antimicrobial and antifungal activity. Steviosid...

This article evaluates the effect of membrane active channel-forming polyene antibiotic (PA) of levorin and its alkyl derivatives on the muscle performance. The membrane channels of muscle cells are capable to transport ions of potassium, sodium, and calcium. In the period of an intensive muscle exercise, the necessity for organic substrates increases and these channels start to work with the g...

Research up to 1993 is reviewed. Various methods for processing, freezing and thawing of semen have been elaborated and their effect on survival and fertility of spermatozoa have been examined in vitro or in fertility tests. Diluents initially used for freezing bull semen had their limitations and were modified or replaced by new media. The freezing diluents investigated included citrate-sugar-...
