A chymotrypsin inhibitor was isolated from <em>Poa pratensis</em> seeds. The inhibitor showed also antytriptic activity. It is a termostable protein, soluble in water, sodium chloride, but insoluble in 5% trichloracetic acid and 0.15 M sulphosalicylic acid.

SummaryWhen crude к-casein was precipitated at pH 3 in the presence of 0·4m-NaCl the supernatant contained up to 80% of the total sialic acid but no detectable cystine or cysteine. Two fractions were obtained from this supernatant by chromatography on DEAE cellulose; one containing 4–6% sialic acid and the other only onetenth of this amount.Most of the sialic acid of the sialic acid-rich fraction was soluble in 12% trichloracetic acid following treatment with rennin. It is suggested that the glycopeptide released by the action of the enzyme on casein originates from this fraction.

The article describes the experimental research on the effect of road maintenance materials on three species of graminaceous plants. The experiment was carried out using technical granular sodium chloride (NaCl) treated with potassium hexacyanoferrate – a road maintenance material most widely applied in wintertime in Lithuania. As an alternative, an organic material obtained on the basis of molasses, patented under the name of Safecote in Europe, was selected for the experiment. Three species of gramineous plants, most frequently used for roadside planting in Lithuania when building new and reconstructing or renovating the existing motor roads, were analysed: perennial ryegrass(Lolium perenne L.), meadow fescue (Festuca pratensis Huds.), and common meadow-grass (Poa pratensis L.).The paper presents experimental findings regarding the effect of road maintenance materials on the parameters of graminaceous plants – the height of the above-ground part and phytomass.

Abstract In the years 2005 - 2006 studies were conducted in a growth chamber and a vegetation hall which compared tolerance to NaCl salinity of seeds and plants of some lawn grasses. The effect of sodium chloride salinity on the germination of 4 species of grasses i.e. Lolium perenne cv. ‘Info’, Festuca rubra cv. ‘Audio’, Agrostis capillaris cv. ‘Niwa’, Poa pratensis cv. ‘Alicja’ and 4 cultivars of Lolium prenne - ‘Nira’, ‘Stadion’, ‘Ronija’, ‘Darius’ was studied. The grass seeds germinated in Petri dishes, in darkness, at the temperature of 24°C. Besides the control, 3 levels of salinity were used in the studies: 100, 200 and 300 mM NaCl. The obtained results demonstrated that the growing level of salinity in the environment significantly decreased the germinating speed, the number of the produced roots, the length of the longest root, and the length of the coleoptile in the seedlings of all studied grass species. Lolium perenne seeds tolerated salinity the best, and next - in a diminishing sequence - those were the seeds of Festuca rubra, Agrostis capillaris and Poa pratensis. However, the obtained data showed that tolerance to salinity of the analyzed cultivars of Lolium prenne decreased in the following sequence ‘Ronija’ > ‘Stadion’ > ‘Nira’ > ‘Darius’. In a vegetation hall tolerance to NaCl salinity of these 4 cultivars of Lolium perenne in the first year growth was compared. The plants grew in pots of 2 dm3 filled with a mixture of universal earth and river sand (3:1 / v:v) with the soil moisture of 70% and 3 levels of salinity: 0, 50, and 100 mM NaCl. The obtained results demonstrated that in all studied cultivars the increase of the salinity level caused a significant decrease of the yield of the leaf dry weight from the successive grass crops, and an increase of the content of sodium, chloride and free proline in them. The greatest tolerance to NaCl salinity in the group of the studied cultivars was shown by ‘Ronija’, medium tolerance - by ‘Darius’ and ‘Stadion’, and the lowest one - by ‘Nira’. This resulted from the degree of accumulation of Na+ and Cl- ions and proline in those conditions. The cultivars with higher tolerance accumulated fewer osmotically active compounds in the leaves.

ABSTRACT Intravenous infusion of isotonic magnesium chloride into young cats with a resultant mean plasma magnesium concentration of 7.7 meq./100 g protein was followed by a significant lowering of the plasma calcium concentration in 90 minutes. The rate of decrease of plasma calcium is consistent with the hypothesis that calcitonin is released by magnesium in high concentrations. There was no decrease in the plasma calcium concentration in cats of the same weight thyroparathyroidectomized 60 min before an identical magnesium chloride infusion or an infusion of isotonic sodium chloride at the same flow rate. The hypercalciuric effect of magnesium could not account for the hypocalcaemic effect of magnesium. Plasma magnesium concentration during magnesium infusion into cats with an intact thyroid-parathyroid gland complex was slightly, but not significantly higher than in acutely thyroparathyroidectomized cats.
