Safety and Efficacy of Ankaferd Blood Stopper in Dental Surgery

Abstract: The aim of this study was to assess retrospectively the hemostatic efficacy and safety of the topical use of Ankaferd Blood Stopper (ABS) in the setting of dental surgery. Following the approval from of the Local Research Ethics Committee ABS as a hemostatic agent in Dentistry, ABS was topically applied by homogeneously spraying to the 25 patients during dental inter- ventions. Based on this retrospective evaluation; Tissue healing was evaluated at the 48th hour. The patients received 1 to 5 mL of ABS; the median dose was 2 mL. Bleeding stopped in median 1.8 seconds (1 to 3 seconds) in the first ABS appli- cation in 20 patients. Five patients needed a second dose of ABS; four of them were given 5 mL ABS totally. No patient had wound infection and the healing process appeared to be normal. ABS is useful for the local hemostasis and wound healing in periodontal surgeries.

ABO and Rh Blood Groups Frequency in Denizli Province

Abstract: The history of the studies on blood groups dates back to early 20th century. Today, more than 600 antigenic structure was detected among 29 blood groups. However, ABO and Rh antigenic structure were taken into consideration in transfusion medicine. To know the rates of the blood groups in a city really helps the citizens in need and blood bank employees. There isn’t any study on frequency of blood groups in Denizli. In this study, we aimed to find out the rates of ABO and Rh blood groups in Denizli province and provide new data to the literature. This study is fulfilled by evaluation of 64.840 people, who were applied to Denizli State Hospital for identification of blood groups between January 2005 and August 2009. Blood groups were examined by gel-centrifugation method. In our study, 58.292 (89.9%) people were found Rh positive and 6548 (10.1%) people were found Rh negative. The frequency of the blood groups A, O, B, AB were found in order as 42.6%, 33.3%,16.8%, 7.4% respectively. The rates of blood groups in Denizli are similar throughout Turkey and in city basis. We consider that this study, which is the first in our city, will contribute to the literature.

Determination of Glycoconjugate Residues of Erythrocytes at Different Age Groups of Rats.

Abstract: Aging is a time-dependent process that contains cell injury caused by molecular damages and eventually functional impairment of tissues and organs. The possible roles of cell surface carbohydrates, which are very important molecules in cell to cell and/or cell to extracellular matrix recognition, on aging process are not yet clear. In this study, glycoconjugate alterations of membrane glycoproteins of erythrocytes in aging organism were evaluated with lectin histochemistry and lectin blotting studies in 1, 4 and 7 months old rats. Lectin histochemistry results indicated that α(2→3) and α(2→6)-linked sialic acids are intensively found in erythrocyte membranes, but this intensity of sialic acids decreases with age. Similar evidences were obtained from lectin blotting studies which performed with same lectins. These results suggest that sialic acid reactivity alters with the age of organism. We thought that (a) sialic acid containing glycoconjugates altered not only with erythrocyte senescence, but also aging process of organism or (b) the number of sialic acid containing erythrocytes decreased by age.
