Study on the current use of four important medicinal plants of Lamiaceae in Bulgaria


In contemporary society various demographic factors lead to changes of people habits to use medicinal plants. A matter of interest is to establish how specific demographic features of people influence the use of herbs. The present survey aimed at determining the current trends regarding the use of four valuable medicinal Lamiaceae species in Bulgaria: thyme, mint, lemon balm and oregano. In the survey, 220 people were interviewed. Demographic profiles of the respondents were evaluated. Then the participants were questioned for the following item: “Do you use any of these herbs: thyme, mint, lemon balm and oregano.” In order to disclose correlations between demographic features of the participants and their answers cross-relationships were analyzed. The majority of respondents reported to use these plants. Mint and thyme were more commonly used herbs. We identified that age of respondents had sufficient influence on the answer to the questionary. Level of education and living regions had moderate impact on the use of relatively lesser utilized herbs – oregano and lemon balm. The analysis showed the persistence of traditional knowledge for these plants. At the same time, the results revealed better knowledge on medicinal plants in groups of better educated people and in urban population.

Popliteal Aneurysms as a Cause for Arterial Insufficiency


Clinical manifestations, possibilities for accurate diagnosis of popliteal aneurysms, and operative approaches applied depending on their location are presented, as well as results from treatment over a four-year period. Popliteal artery aneurysms accounted for 5.63% of all 266 cases of acute arterial insufficiency. The mean age of the patients was 68.8 years, and the male:female ratio – 4:1. In five patients (33.33%), the localization of aneurysm was unilateral. In 80% of the cases with bilateral popliteal aneurysms, the aneurysms were combined with aneurysms of other locations. The surgical technique applied was posterior approach with resection of the aneurysm and interposition of a polytetrafluoroethylene (PTFE) prosthesis. The early patency rate of the reconstructed segment was 100%. Late patency rate of the reconstructed segment was 90.9%. Despite the better late results in femoropopliteal reconstruction, we think that a posterior approach with prosthesis implantation is better because it saves the great saphenous vein. The presence of multiple aneurysms in the patients studied (80%) determined the low survival at 5 and 10 years, which makes it comparable to the results from applying the two surgical methods.
