Summary Background: To evaluate the implementation of the guidelines of the German Society of Phlebology for venous crural ulcer a survey was conducted during the annual meeting of the German Society of Phlebology 2008 in Bochum. Methods: All 719 medical participants got an anonymized questionnaire asking for supply of crural ulcer in their institution. Results: The recurrent 66 questionnaires (9.2%) were filled by colleagues from practice or hospital, mostly surgeons, dermatologists, phlebologists and vascular surgeons. As basic diagnostics vein doppler (56.1%), duplex (75.8%) or measurement of brachial-ankleindex (83.3%) were performed. Compression therapy is used in all institutions. Mainly used wound dressings are polyurethane foam dressings, alginates, hydrocolloids and silver dressings. About 2/3 conduct surgical therapy of ulcers. Conclusion: Supply of ulcus cruris by the participants of the annual meeting of the DGP corresponds mainly, but not in all aspects to the guidelines. Further efforts for a spread of the guidelines are necessary.

Reduced Pressure

In order to prepare standardized extract, optimization of extraction conditions of grape seed has been done. These conditions are type of menstrum (50, 70 and 96% of ethanolic solution), length of extraction (1, 2 and 4 hours) also method of evaporation (reduced pressure and opened air). Activity on free radical scavenger used as parameters to determine optimum conditions. Based on EC50 (concentration which scavenge 50% amount of free radical) can be concluded that optimum condition for extracting antioxidant active compound from grape seed are 70% ethanolic solution as menstrum, length of extraction 1 hour and evaporation on opened air use water bath.

Reduced Risk

Interest in the biological role of bioactive compounds present in medicinal herbs has increased over the last years. Of particular interest are plants that have an anti-Alzheimer activities. Several plants can be useful for Alzheimer (AD) management. Such as these which have anti-inflammatory activity, acetylcholinesterase (AChE) inhibitory action, antiapoptotic, slow the aggregation of amyloid peptide and antioxidant activities. Grape seed extract (GSE) is a complex mixture of several compounds, mostly represented by polyphenols and flavonoids. Their consumption is safe and is recognized to exert several health benefits. GS flavonoids have been associated with the reduced risk of chronic diseases, we present some findings on the potential benefits of GSE for the treatment of AD.
