Determination of Nutrient Contents and In vitro Gas Production Values of Some Legume Forages Grown in the Harran Plain Saline Soils.

The aim of this study was to determine the nutritive value of some legume species in salt-affected soils of South-East Anatolian region using chemical composition and in vitro gas production kinetics. In this study, Lotus corniculatus, Trifolium alexandrinum, Medicago sativa were sown and tested in four different locations. A 3 by 4 factorial design with 3 legume species and 4 salt levels (non salty electrical conductivity (EC)<4 dS/m; low salt: 4 dS/m>EC<8 dS/m, medium saline: 8 dS/m>EC<16 dS/m and high salt: 16 dS/m>EC) was used in the study. Results indicated that salinity and plants had no significant effect on ash and ether extract. Dry matter (DM), acid detergent fiber, digestible dry matter, dry matter intake (DMI) were affected by plant, salinity and plant×salinity interaction. On the other hand neutral detergent fiber, relative feed value (RFV), and DMI were affected by salinity and plant×salinity interaction. Mineral contents were affected by plant species, salinity and salinity×plants interactions. In vitro gas production, their kinetics and estimated parameters such as were not affected by salinity whereas the gas production up to 48 h, organic matter digestibility, metabolizable energy (ME), and net energy lactation (NEL) were affected by plant and plant×salt interaction. Generally RFVs of all species ranged from 120 to 210 and were quite satisfactory in salty conditions. Current results show that the feed value of Medicago sativa is higher compared to Lotus corniculatus and Trifolium alexandrinum.

Does eradication of Helicobacter pylori reduce hypergastrinaemia during long term therapy with proton pump inhibitors?

OBJECTIVES: To evaluate the effect of Helicobacter pylori (Hp) eradication therapy on blood gastrin levels in long-term PPI users, since proton pump inhibitors (PPIs) and Helicobacter pylori (Hp) are major causes of hypergastrinaemia. DESIGN: A prospective study. SUBJECTS: Twenty seven Hp (+) patients enrolled in the study. Twenty were given eradication treatment (ET group), and the rest were given symptomatic treatment (ST group). Those who remained Hp (+) after eradication therapy were also added into the ST group. Lansoprazol 30 mg/day was given to both groups for three months thereafter. RESULTS: Fasting and non-fasting blood gastrin levels (FGL and NFGL) were measured initially and one month and four months after treatment. At the end of fourth month, FGL was significantly higher than both initial and first month level (p < 0.01) in the ST group. NFGL in this group did not change significantly (p > 0.05) after eradication therapy. In the ET group, FGL was significantly higher in the fourth month than the first month (p < 0.001) and than the initial level (p < 0.05). NFGL was higher, but not statistically in the fourth month than in the first month (p > 0.05) and significantly lower than the initial level (p < 0.05) in this group. CONCLUSION: We suggest that testing for Hp positivity and treating it if detected would be an appropriate approach to avoid hypergastrinaemia, especially in candidate patients for long term PPI treatment.

Inhibition of neuraminidase with neuraminic acid C-glycosides.

Neuraminic (sialic) acid based alpha-C-glycosides have been synthesized and their inhibitory activity towards bacterial neuraminidase (sialidase) was examined. While some C-glycosides were found to be potent inhibitors (Ki 15-30 microM) of this neuraminidase, others afforded no measurable activity. The structure-activity relationship of these C-glycosides is discussed in the context of other previously reported sialidase inhibitors.
