گوشت قرمز یکی از مهم ترین فرآورده های دامی در تأمین پروتئین و انرژی می باشد که در حمل ویتامین های محلول در چربی نیز حائز اهمیت می باشد. انسان مانند سایر مهره داران اسید های چرب ضروری (لینولئیک و آلفا لینولنیک) مورد نیاز خود از طریق غذا تأمین می نماید. اسید های چرب ضروی پیش ساز اسید های چرب غیر اشباع با چند پیوند دوگانه هستند. اسید لینولنیک پیش ساز اسیدهای چرب امگا 3 و اسید لینولئیک نیز پیش ساز ...
Efflux of osmolyte amino acids during isovolumic regulation in hippocampal slices.
The efflux of potassium (K(+)) and amino acids from hippocampal slices was measured after sudden exposure to 10% (270 mOsm), 25% (225 mOsm) or 50% (150 mOsm) hyposmotic solutions or after gradual decrease (-2.5 mOsm/min) in external osmolarity. In slices suddenly exposed to 50% hyposmotic solutions, swelling was followed by partial (74%) cell volume recovery, suggesting regulatory volume decrea...
متن کاملLocations of amino acids in brain slices from the rat. Tetrodotoxin-sensitive release of amino acids.
1. Amino acids, particularly glutamate, gamma-aminobutyrate, aspartate and glycine, were released from rat brain slices on incubation with protoveratrine (especially in a Ca(2+)-deficient medium) or with ouabain or in the absence of glucose. Release was partially or wholly suppressed by tetrodotoxin. 2. Tetrodotoxin did not affect the release of glutamine under various incubation conditions, no...
متن کاملLong-lasting facilitation of 4-amino-n-[2,3-(3)H]butyric acid ([(3)H]GABA) release from rat hippocampal slices by nicotinic receptor activation.
In this study we explored the effect of the stimulation of nicotinic acetylcholine receptors located on interneurons by measuring 4-amino-n-[2,3-(3)H]butyric acid ([(3)H]GABA) release and monitoring [Ca (2+)](i) in superfused hippocampal slices. In the presence of 6-cyano-7-nitroquinoxaline-2,3-dione, (+/-)-2-amino-5-phosphonopentanoic acid, and atropine, i.e., under the blockade of N-methyl-D-...
