• Endogenous biosynthetic capacities for prostaglandin (PG)E2, thromboxane (TX)B2 (a stable degradation product of TXA2) and 6 keto-PGF1α (a stable degradation product of PGI2) in the brainstem fractions of stroke-resistant spontaneously hypertensive rats (SHRSR) and control Wistar-Kyoto rats (WKR) were determined with novel methods and presented in an original report. In comparison with WKR, it is characteristically found that TXB2 synthesis is increased in excess of threefold in the pons-medulla oblongata of SHRSR, while being decreased by 75% in the hypothalamic region of SHRSR (0.01<p<0.05). On the other hand, the biosynthesis of PGE2 is adaptively elevated in both hypothalamus and pons-medulla oblongata regions of each animal, although the PGI2/PGE2 ratio was lowered in both these regions of SHRSR.
