Investigation of Matrix Metalloproteinas Levels in Preeclamptic/Eclamptic Pregnancy
(Yuzuncu Yil Universitesi Tip Fakultesi, 2023) Özmen, E.; Şahin, H.G.
The present research was designed to investigate levels of matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), and their respective tissue inhibitors, tissue matrix metalloproteinase inhibitor-1 (TIMP-1) and tissue matrix metalloproteinase inhibitor-2 (TIMP-2), in eclamptic and preeclamptic pregnant women. In this work, undertaken in the Obstetrics and Gynecology Department of the Yüzüncü Yıl University Faculty of Medicine Health Practice and Research Hospital, eclamptic (n=28), preeclamptic (n=28), and healthy pregnant women (n=24) were enrolled and their levels of MMP-2, MMP-9, TIMP-1, and TIMP-2 were studied by micro-ELISA method. No statistically meaningful differences were identified between the study groups for MMP-2 (p=0.786). When the ratios of MMP-2 to TIMP-2 of the three groups were examined, again, no statistically meaningful differences were noted (p=0.788). While a meaningful difference was not seen between the preeclamptic and eclamptic groups for MMP-9 and TIMP-1, significantly lower values of MMP-9 and TIMP-1 were obtained in both groups upon comparison to the control group (p=0.001 for MMP-9, p<0.000 for TIMP-1). When the MMP-9/TIMP-1 ratios of the groups were evaluated, a statistically meaningful difference did not exist between women with preeclampsia and controls; however, this ratio was higher among women with eclampsia in comparison to the preeclampsia and control groups and this finding was statistically significantly (p=0.011). Imbalanced levels of MMP-9 and TIMP-1 could be used as a marker in efforts to predict preeclampsia and especially eclampsia. However, larger clinical studies are needed to reveal these interactions in more detail. © 2023, Yuzuncu Yil Universitesi Tip Fakultesi. All rights reserved.
The Macroanatomic Study on Terminal Branches of the External Jugular Vein in Akkaraman Sheep
(Scientific and Technical Research Council of Turkey, 1996) Nur, I.H.; Özmen, E.
Ten heads of akkaraman sheep of different sex were used. Latex was injected through the external jugular vein for investigation purposes. The following was determined: Ventral cerebral vein arises from the external jugular vein and it anastomoses with the emissary vein of the jugular foramen. The dorsal cerebral vein enteres the temporal meatus and originates from the superficial temporal vein. The linguofacial vein arisis from the external jugular vein. The lingual vein takes its origin from the linguofacial vein the Pterygoid plexus consisted of several anatomotic veins located between the pterygoid muscles the venous drainage of the nasal mucosa is mainly via the sphenopalatina vein.
