[Content of prostaglandin biosynthesis precursors in the kidney lipids in the development of spontaneous arterial hypertension].
The content of linoleic (18 : 2 omega 6), arachidonic; (20 : 4 omega 6) and eicosatrienic (20 : 3 omega 9) acids was studied and compared in lipids of the renal cortex and papilla of spontaneously hypertensive Okamoto-Aoki rats (SHR) and normotensive Wistar rats (NR) aged 10 days, 1, 2 and 4 months. The level of 18 : 2 omega 6 in lipids of the renal cortex and papilla of SHR was lower at the prehypertensive stage (10 days) and at the stage of persistent hypertension as compared to that seen in NR. The content of 20 : 4 omega 6 in phospholipids and triglycerides of the cortex and in phospholipids of the papilla of SHR did not differ from that in NR. In triglycerides of the papilla of SHR of all age groups, the content of 20 : 4 omega 6 was higher than in NR. In phospholipids of SHR cortex, the content of 20 : 3 omega 9 was higher than that in NR. As for lipids of the papilla, 20 : 3 omega 9 was not detectable either in NR or SHR. It is concluded that the data obtained are of interest for the characteristics of the renal prostaglandin system in SHR.
