Antifibrinolytic drugs provide important pharmacological interventions to reduce morbidity and mortality from excessive bleeding during surgery and after trauma. Current drugs used for inhibiting the dissolution of fibrin, the main structural component of blood clots, are associated with adverse

The effect of dietary fatty acid composition on plasma lipids and eicosanoid production was studied in normolipidemic men. Approximately 75% of the fat in the diet was provided by a mixture of fats (MF) during the 6-d pre and postperiods and either canola oil (CO) or sunflower oil (SO) during the

A virus causing chlorotic mottling symptoms on sunflower was found in various locations in Argentina. Symptoms were small chlorotic spots, yellow blotches on leaves, and plant stunting. Virus transmission efficiency by mechanical inoculation was 73 to 100%, and by Myzus persicae was 31 to 49%. The

CCC was shown to be effective in retarding stem growth of sunflower; this effect was overcome by gibberellic-acid application. Using an agar-diffusion technique, the gibberellin (GA) content of sunflower apices treated with CCC was found to be significantly reduced as compared to controls.

With two extraction procedures differing in the very first extraction steps two cytokinins from a total amount of 180 kg sunflower leaves could be isolated. One of these cytokinins is identified as zeatin by Rf values, UV absorption, melting point of its picrate and its biological activity. The same
