Mother (nature) knows best

ficantly decrease the systolic blood pressures of SHRs at three and six months. The concurrent ingestion of linoleic acid seemed to be inversely related to elevated blood pressure levels.

The memory of Spontaneously hypertensive rats (SHRs) at three, four, and five months were assessed with a maze and the results indicate that the latency period to find the platform was consistently significantly higher in the spontaneously hypertensive rats as compared to their controls. These findings clearly indicate that hypertension is associated with decline in spatial reference memory, consistent with those reported by other researchers in the field.

In the three month-old SHRs, the effects of linoleic acid on spatial reference memory indicated no significant difference in the latency period. However, LA administration to six and nine month old SHRs, resulted in significant decline in spatial memory. This indicates that linoleic acid administration produced a significant improvement of spatial reference memory in these rats.

Dopamine plays an important role in learning and memory. The D1 receptor in the hippocampus facilitates acquisition and retention of different working memory tasks In addition, D1 receptors are located on blood vessels. Activation of D1 results in widening of the arteries. Dopaminergic D1 binding kinetics were evaluated in the hippocampus, thalamus, hypothalamus and cortex of the control and SH rats. Results obtained indicate that controls had significantly higher D1 receptor density in all brain areas studied as indicated by higher Bmax as compared to the Spontaneously Hypertensive rats. Since SHRs exhibited a deficit in spatial reference memory, this suggests that D1 receptor density may be positively linked to spatial reference memory. This further supports the assertion that administering linoleic acid to SHRs did not only result in improvement of spatial reference memory but also significantly increased Bmax of D1 dopamin
