    Abstract: Aim: Total parenteral nutrition (TPN) is a technique which is use to give vitally mandatory substances in to the venous compartments whenever the gastrointestinal system cannot be used by the patients. Telomerase catalyzes DNA synthesis, which is necessary to maintain telomere length and stabilize the genome to allow continued cell proliferation. In this study, we explored the effects of TPN administration on telomerase reverse transcriptase (TERT) expression in various tissue and serum telomerase level. Material and Methods: In this study a number of 42 same-aged albino, equal number of male and female, new zealand rabbits were use, divided in to three groups. Group 1 rabbits received TPN for 10 days via a central venous catheter. Group 2 received 50 mL/ kg/day physiological saline via a central venous catheter. Group 3 served as the control group. The rabbits were sacrificed after 10 days, and serum telomerase levels were measured by enzyme-linked immunosorbent assay. TERT expression in gonadal, liver, jejunum, and skin tissues were determined immunohistochemically. Blood samples were obtained before and after TPN and saline administration in the TPN and serum saline groups, respectively, and at the end of the experiment in the control group. Results: Telomerase expression in liver, gonads and serum level of TPN group was significantly higher than control and serum saline groups. Conclusion: TPN may be a positive effect in liver and gonadal telomer kinetic. However, we think that TPN increases DNA damage throughout the body.

    Use of angiographic embolization in trauma-induced pediatric abdominal solid organ injuries
    (Turkish Assoc Trauma Emergency Surgery, 2019) Gurunluoglu, Kubilay; Ceran, Canan; Yildirim, Ismail Okan; Kutlu, Ramazan; Sarac, Kaya; Yildiz, Turan; Bayrakci, Ercan
    BACKGROUND: Knowledge of the utility of angiographic embolization (AE) in pediatric cases of blunt abdominal solid organ trauma injuries is limited. The current study is an examination of AE as an effective and reliable method to control bleeding in patients with persistent bleeding due to blunt trauma-induced abdominal solid organ injury. METHODS: This was a retrospective examination of patients < 17 years of age who had experienced blunt abdominal solid organ injury and who presented at a single institution within 4 years. A statistical analysis of the data was performed. RESULTS: The mean length of intensive care unit stay was 4 days for those who underwent embolization (n= 11), and the mean length of hospital stay was 12 days. The average pre-AE blood loss, as measured by the decrease in hematocrit (%) from admission to embolization, was -7.33 +/- 5.3% (p< 0.001). The average post-AE blood loss, as measured by the change in hematocrit 72 hours post AE, was 2 +/- 0.97% (p> 0.05). All of the patients were discharged with a full recovery. CONCLUSION: AE was a safe and effective method to control solid organ hemorrhage in pediatric patients with blunt abdominal injuries.
