Lilium martagon L. is a perennial geophyte species belonging to the large Liliaceae family. Its population is at the status of ‘’VU’’ in the Red Data Book of Turkish Plants, and along with many European countries, it is included in Turkey’s list of plants that are endemic and imperiled. This study analyzed the potential of producing Lilium martagon L. with teeth. Four different hormones (IAA: iIndole-3-acetic acid; IBA: indole-3-butyric acid; NAA: naphthylacetic acid; and GA3: gibberellic acid) were applied in three doses (1,000, 3,000, and 5,000 ppm) on apical, medium, and basal parts and after 120 days, six morphological characteristics were determined. According to the results, 1,000 ppm IBA implementation is seen as the most effective hormone dose implementation on morphological characters. According to the effect of fraction position, for all characters the individuals formed by the pieces taken from the bottom parts of teeth are included in the first homogeneous group. Also, it is revealed that each of the apical, medium, and basal parts were obtained by cutting nail-like scales on the corpus in three equal pieces and have the potential for meristematic reproduction ability.

It has been suggested that some microorganisms may play a role in the etiology or progression of atherosclerotic plaques. The purpose of this study was to assess for the presence of Helicobacter pylori and cytomegalovirus (CMV) DNA using polymerase chain reaction (PCR) technique in vascular-wall specimens obtained during autopsy. Four to 5 mm long samples from 3 different vascular wall specimens (coronary, carotid and abdominal aortas) of 30 patients (23 male, 7 female) were taken for pathologic and microbiologic investigations during autopsy. H. pylori DNA was found in 48.2% atherosclerotic and 19.6% non-atherosclerotic vascular wall specimens, whereas CMV DNA was found in 37.9% atherosclerotic and 32.7% non-atherosclerotic vascular wall specimens. In terms of CMV DNA detection, no statistically significant differences between the atherosclerotic and non-atherosclerotic groups were present (P>0.05). However, there was a statistically significant difference between the atherosclerosis and non-atherosclerotic groups in terms of H. pylori DNA in coronary and abdominal aorta arteries (p = 0.016 and p = 0.0029 respectively) but not in carotid arteries (p= 1.00). In conclusion, the correlation between H. pylori and atherosclerosis could be suggested. These finding warrant further investigation regarding the role of H. pylori in atherosclerosis.
