Abstract：
:The fatty acid patterns of serum triglycerides and FFA in SHR and in normotensive controls aged 4, 8 and 26 weeks were estimated by gas-liquid chromatography. In serum triglycerides of SHR, the percentage of linoleic acid (C18:2) was lower and the content of arachidonic acid (C20:4) higher than in age-matched control animals. A continuous increase in palmitic (C16) and linoleic acids as well as a decrease in arachidonic acid has been found with advancing age, the most striking differences existing between 4- and 8-week-old animals, i.e. before onset of arterial hypertension in SHR. In the pre-hypertensive stage, the percentage of arachidonic acid was about 3 times as high as in later stages in SHR. This gradation was, however, even more pronounced in normotensive control rats. The C18:2/C20:4-ratio of triglycerides was lower in SHR but increased with age in both groups reaching a 5--8-fold level. Similar behavior of the FFA fatty acid pattern was less marked. Alterations in levels of linoleic and arachidonic acids are of interest because of their pathogenic role as precursors of prostaglandins in the development of genetically spontaneous hypertension in rats. The results are discussed in connection with the hypotensive effect of a linoleic acid-rich diet recently reported in hypertensive rats.
