The effect of selective dietary sodium and (or) chloride loading on blood pressure and renal blood flow (RBF) in the rat angiotensin II (AII) model of hypertension was determined. AII (200 ng/min) or saline was infused intraperitoneally. Diets were provided with either high or low concentrations of sodium, chloride or both ions for 22 days. The blood pressure of saline-treated animals was not increased by the high sodium chloride diet. Animals on a high sodium, high chloride diet had a significantly greater increase of blood pressure at 8, 15, 18, and 22 days of AII infusion compared with AII-treated animals on a low sodium, low chloride diet (p < 0.05). Selective dietary loading of either high sodium or chloride in AII-treated rats produced no greater elevation of blood pressure than AII with the low sodium, low chloride diet. Selective high dietary chloride was associated with a lower RBF in AII- and vehicle-treated rats compared with low dietary chloride. The chloride effect on RBF was greater in AII-treated animals. In conclusion, both sodium and chloride are necessary to produce the maximum increase of blood pressure in AII animals. AII enhances the decreased RBF induced by dietary chloride.Key words: angiotensin II, sodium chloride, blood pressure.

Ruppia maritima L. is a submerged halophyte which occurs frequently in estuaries where sodium chloride is the dominant salt. Unlike terrestrial halophytes, R. maritima does not possess any specialised salt-secreting structures such as salt glands. Knowledge of salt tolerance mechanisms in this plant is important to our understanding of its biology. In a previous study it was shown that leaf epidermal cells of R. maritima, which possess transfer cell characteristics, are implicated in salt regulation. In the present investigation, the effect of calcium (Ca) on salt tolerance of leaf epidermal cells was studied since Ca has been found to be an important factor in resistance to salt stress in terrestrial plants.Plants were grown in artificial seawater of high salinity (33%) and at two different Ca concentrations : 400 ppm (high Ca) and 100 ppm (low Ca).
