in this study, chemical composition, fatty acid (fa) profile and oil characteristics of seeds of salvia leriifolia benht collected from different regions of iran. all samples were rich in oil (24-28.5% dry weight basis), protein (24.5-28.5%) and crude fiber (13.1-16.6%). the mean values for ca, p, k, mg, fe, mn, cu, na and zn were found at the levels of 3866, 2970, 3141, 2584, 57, 18.5, 9.0, 10...

Preoperative acid studies and early postoperative insulin tests in 275 patients undergoing various forms of vagotomy have been related to recurrent ulceration. Follow-up time has been from two to nine years, mean 4-3 years. Recurrence is directly related to basal acidity in both tests but is not related to stimulated acid levels preoperatively. In the insulin tests higher levels of acidity afte...
