Abstract
OBJECTIVES Some of the most common problems after kidney transplant are urologic complications, including ureterocystoanastomosis leakage and stenosis with the development of severe renal graft complications. Isolated plasma contains active substances that cause the activation of various growth factors for the processes of tissue repair or regeneration, has an anti- inflammatory effect, activates angiogenesis, and reduces the risk of infectious complications. Platelet-rich plasma is actively used to stimulate bone regeneration, heal wounds and ulcers on the skin, enhance reconstruction of the larynx and trachea, and ameliorate urethral damage, among other uses. This study was developed to evaluate the positive effect of platelet-rich plasma on the healing process of an anastomotic wound in a model of ureterocystoanas-tomosis in rats. MATERIAL AND METHODS We randomized 14 Wistar albino male rats into 2 groups: group 1 included 7 rats that received platelet-rich plasma after ureterocystostomy; group 2 was the control group and included 7 rats that underwent ureterocystostomy without platelet-rich plasma. On postoperative day 7, all animals were euthanized, and the anastomosis area was resected for determination of the tissue hydroxyproline levels and histopathology examination. RESULTS Tissue hydroxyproline levels were 767 ± 62.9 μg/g in group 1 and 256 ± 28.0 μg/g in group 2. Tissue hydroxyproline levels were significantly higher in group 1 compared with group 2 (P < .05). There were no significant differences in epithelial damage, acute inflammation, or fibrosis between the tissue samples of both groups. CONCLUSIONS The results of this study show that the use of platelet-rich plasma during ureterocystostomy produces a positive effect. Our further research will be devoted to the use of autologous platelet-rich plasma in ureterocystostomy in big models.

Abstract
BACKGROUND Anastomotic leak constitutes a major problem in abdominal surgery. Technical insufficiency, topical or systemic factors contribute to disrupted healing of the performed bowel anastomosis and result in anastomosis leakage, with detrimental effects on patient postoperative outcomes. Despite the investigation of several factors and the invention of protective materials, the ideal agent to prevent anastomotic leaks is yet to be determined.
AIM To study the effect of platelet rich plasma (PRP) on the healing of bowel anastomoses.
METHODS A systematic literature search was performed in PubMed, EMBASE, and Scopus databases to identify studies investigating the effect of PRP application on bowel anastomosis.
RESULTS Eighteen studies were eligible with a total population of 712 animals including rats (14 studies), rabbits (2 studies) and pigs (2 studies). No postoperative complications were reported following PRP application. Fourteen out of 18 studies reported a statistically significant higher anastomosis bursting pressure in PRP groups compared to control either in healthy animals or animal models with underlying condition or intervention, such as intraperitoneal chemotherapy or peritonitis. Similar results were reported by ten studies in terms of tissue hydroxyproline levels. One study reported significant increase in collagen deposition in PRP groups. PRP application resulted in significantly decreased inflammatory cell infiltration in the presence of peritonitis or intraperitoneal chemotherapy (6 studies).
CONCLUSION The application of PRP is associated with improved bowel anastomosis outcomes, especially in animal models having an underlying condition affecting the normal healing process. PRP application seems to augment the normal healing process under these circumstances. However, further studies are needed to investigate the potential role of PRP on bowel anastomosis healing, especially in clinical settings.

Abstract
OBJECTIVE Delayed primary suture closure of gastric perforation is prone to dehiscence hence the repaired area should be buttressed to avoid re-operation. We aimed to investigate whether DuraSeal®(DS) has a potent adjunctive effect on delayed closure of gastric perforation comparing with 2-octly-cyanoacrylate(CYN) in an experimental model. METHODS Sixty rats were randomly divided into 6 groups. All subjected to gastric perforation, subsequently perforation areas were repaired by primary suturing, delayed repair was performed 12 h after surgery. According to DS or CYN application on anastomosis, the groups were classified as control(C), delayed control(CD), closure with CYN(CYN), delayed closure with CYN(D-CYN), closure with DS(DS), delayed closure with DS(D-DS).After euthanization on POD 7,anastomotic bursting pressure(ABP) were measured. Tissue samples were taken for histopathological examination and hydroxyproline(TH) assessment. RESULTS Delayed condition significantly reduced ABP and TH levels in CD group comparing with all groups(p < 0.01).Either CYN or DS application on delayed repaired area significantly raised the measure of ABP and TH up to the levels of C group(p < 0.05,comparing with CD).Microscopically,either CYN or DS application significantly improved tissue necrosis, submucosal bridging and collagen formation comparing with CD group(p < 0.012).There were no difference regarding ABP, TH and tissue healing between each CYN and DS groups. CONCLUSION DuraSeal® application on sutured gastric perforation area yielded a significant adjunctive effect both in normal and delayed conditions. However, DuraSeal® revealed no superior effect to CYN in both condition.Our results demonstrated that the clinical use of DuraSeal® can be considered for reinforcing the sutured line in patients undergoing delayed surgery for gastric perforation.

Abstract
Purpose 5-flourourasil (5-FU) is commonly used for early intraperitoneal chemotherapy in colorectal or appendiceal cancer patients with peritoneal carcinomatosis. Due to its effect, anastomosis healing can be impaired and leads to anastomotic leakage. In this study, we aimed to investigate the potential healing effect of platelet-rich plasma (PRP) on colonic anastomosis impaired by intraperitoneal 5-flourouracil application. Methods After ten rats were sacrificed for preparing PRP, forty Wistar-albino rats were subjected to colonic anastomosis, and randomly allocated into four groups including 10 rats each. According to receiving PRP and/or 5-FU application, the groups were formed as control (C), 5-FU without PRP (CT), anastomosis with PRP (C-PRP), and 5-FU with PRP (CT-PRP). CT and CT-PRP groups also received 5-FU intraperitoneally on postoperative day 1 (POD 1). All animals were euthanized on pod 7. The body weight change, anastomotic bursting pressure (ABP), tissue hydroxiprolin (TH) and histopathological examination of each group were analyzed. Results 5-FU application significantly reduced ABP levels when compared with group C, C-PRP and CT-PRP (for each comparison, p<0,01). PRP application in CT-PRP group raised the measure of ABP up to the levels of C group. Although tissue hydroxyproline levels (THL) levels of CT-PRP group were found higher than CT group, it was not significant (p=0.112). Microscopically, comparing with CT group, PRP application significantly promoted the healing of colonic anastomosis subjected to 5-FU application by improving tissue edema, necrosis, submucosal bridging and collagen formation (p<0.05). Tissue healing in CT-PRP group was observed as good as the control groups. (C, C-PRP, p=0.181, p=0.134; respectively). Conclusion PRP administration on colonic anastomosis significantly promotes the healing process of anastomosis in rats receiving 5-FU. This result encourages further clinical use of PRP to reduce the frequency of AL in patients receiving EPIC.

Abstract
BACKGROUND Hyperthermic intra-peritoneal chemotherapy (HIPEC) performed in patients with peritoneal carcinomatosis has a cytotoxic effect on tumour cells. This cytotoxic effect also adversely affects the wound healing of anastomosis, which is frequently undertaken in this patient group, and causes anastomotic leakage and intestinal fistulas. Platelet-rich plasma (PRP) gel has been used in wound healing and has shown efficacy. We investigated the effect of PRP gel on colon anastomosis healing in rats treated with 5-fluorouracil (5-FU). METHODS Twenty-four rats were divided into three groups, each containing eight rats: group 1 (control) underwent colon anastomosis alone; group 2 (5-FU) underwent a colon anastomosis and HIPEC; and group 3 (5-FU + PRP) underwent a colon anastomosis and HIPEC and received topical PRP gel. The rats were sacrificed on the post-operative day 7 and the anastomotic bursting pressure (ABP) was measured. Tissue samples were obtained to measure the hydroxyproline level and investigate the histopathological changes on the anastomosis line. RESULTS ABP was higher in the control and 5-FU + PRP groups than in the 5-FU group (P = 0.009, P = 0.047). The tissue hydroxyproline levels were higher in the control and 5-FU + PRP groups than in the 5-FU group (P = 0.001, P = 0.030). The histopathological findings of the 5-FU + PRP group were better than those of the 5-FU group. CONCLUSION This study showed that the application of PRP gel to colon anastomoses increased ABP in rats treated with HIPEC using 5-FU. It also showed positive effects on anastomotic healing by increasing the tissue hydroxyproline levels on the anastomosis line and reducing the inflammatory response.

Abstract
Purpose Hyperthermic intraperitoneal chemotherapy (HIPEC) is a novel treatment option for peritoneal surface malignancies. Due to cytotoxic effects of chemotherapeutic agents, anastomosis healing can be impaired and lead to leakage rates higher than conventional intestinal surgery. In this experimental study, we aimed to investigate the effects of platelet-rich plasma (PRP) on colonic anastomosis in rats that received HIPEC with oxaliplatin. Methods Thirty rats were divided into 3 groups. Group 1 was determined as control group and hyperthermic saline perfusion was performed after colon anastomosis. In group 2, colon anastomosis then hyperthermic oxaliplatin perfusion was performed. In the last group, the colonic anastomosis was enhanced by PRP gel and then hyperthermic oxaliplatin perfusion was performed. All the rats were reoperated on postoperative day 7 and anastomotic bursting pressure values were recorded. Tissue samples were taken for hydroxyproline assay and histopathological examination. Results Control group had higher anastomotic bursting pressure value than group 2 and group 3 (P < 0.001). There were significant differences in anastomotic bursting pressure between groups 2 and 3 (P < 0.001). Group 2 had significantly lower hydroxyproline levels than group 3 and control group (P < 0.001). Histopathological examination revealed that PRP application reduced inflammatory response. Conclusion PRP application on colonic anastomosis improves anastomotic healing and can reduce anastomosis related complications and stoma creation; though further clinical studies are needed.

Abstract
Hyperthermic intraperitoneal chemotherapy (HIPEC) has cytotoxic effects on tumour cells but also negative impacts on anastomotic healing. Platelet-rich-plasma (PRP) is used for wound care but data about effects on gastrointestinal anastomosis are limited. In this experimental study, we aimed to investigate the effects of PRP application on colon anastomosis in rats those received HIPEC with cisplatin. Five rats were sacrificed to obtain PRP gel. Thirty rats were divided into three groups; Group 1: control group, Group 2: colon anastomosis and HIPEC with cisplatin, and Group 3: colon anastomosis enhanced by PRP and HIPEC with cisplatin. The rats were re-operated on postoperative day seven and anastomotic bursting pressure (ABP) was recorded. Also, tissue samples were taken for hydroxyproline assessment and histopathological examination. There were significant differences in ABP between Groups 2 and 3, and also those groups had lower ABP compared with the control group. Group 3 had significantly higher hydroxyproline levels and had better histopathological findings than group 2. According to our findings, we suggest that PRP application improves the anastomotic healing by increasing anastomotic bursting pressure, hydroxyproline levels, and decreasing inflammatory response. Further clinical studies are needed to prove our hypothesis.

Abstract
PURPOSE To compare platelet rich plasma (PRP) and fibrin glue about the effect of anastomotic healing. METHODS Thirty six Wistar-Albino male rats diveded into 3 groups according to control(Group1), PRP (Group 2) and fibrin glue(Tisseel VH) (Group 3). The colon was transected with scissor and subsequently an end to end anastomosis was performed using continuous one layer 6/0 vicryl sutures. Postoperative 7th day effect of anastomotic healing measuring with tissue hydroxyproline(TH) level and anastomotic bursting pressure(ABP); moreover comparison of cytokine (IL-6 and IL-10) and procalcitonin levels on 1st,3rd and 7th days. RESULTS There was no statistically significant difference of the ABP and hydroxyproline levels between PRP and fibrin glue on the 7th day. There was no statistically significant difference between levels of proinflammatory cytokine (IL-6) (P=0.41), anti-inflammatory cytokine (IL-10) (P=0.35), and procalcitonin levels (P=0.63) on 1, 3 and 7 days. CONCLUSION Fibrin glue and platelet rich plasma are shown to be effective in healing intestinal anastomoses without superior to each other.

Abstract
Purpose: To examine a correlation of micro-PET images with photographic images of the digestive organs in abdominal sepsis model. Methods: Male Wistar rats weighing 265±18g were used. Abdominal sepsis was induced by ligature and cecal puncture. Micro-PET Images from abdominal cavity septic foci were obtained using 18-Fluoro-deoxyglucose, looking for a correlation with photographic images of abdominal cavity organs. Pearson's correlation test was used. Results: The mean standard uptake values (SUV) and lesion areas were 2.58±0.63SUVbwg/ml and 546.87±300.95mm2, respectively. There was a strong positive correlation between the two variables (r=0.863, p=0.137), which resulted in a coefficient of determination r2?0.75, meaning that 75% of SUV variation is explained by the lesion areas of digestive organs. Conclusion: Micro-PET allows high throughput assessment of lesion count and volume in pre-clinical rat model of CPL abdominal sepsis.

Abstract
Renal ischemia-reperfusion injury is a major cause of acute renal failure, causing renal cell death, a permanent decrease of renal blood flow, organ dysfunction and chronic kidney disease. Platelet-rich plasma (PRP) is an autologous product rich in growth factors, and therefore able to promote tissue regeneration and angiogenesis. This product has proven its efficacy in multiple studies, but has not yet been tested on kidney tissue. The aim of this work is to evaluate whether the application of PRP to rat kidneys undergoing ischemia-reperfusion reduces mid-term kidney damage. A total of 30 monorrenal Sprague-Dawley male rats underwent renal ischemia-reperfusion for 45 minutes. During ischemia, PRP (PRP Group, n = 15) or saline solution (SALINE Group, n = 15) was administered by subcapsular renal injection. Control kidneys were the contralateral organs removed immediately before the start of ischemia in the remaining kidneys. Survival, body weight, renal blood flow on Doppler ultrasound, kidney weight, kidney volume, blood biochemistry and histopathology were determined for all subjects and kidneys, as applicable. Correlations between these variables were searched for. The PRP Group showed significantly worse kidney blood flow (p = 0.045) and more histopathological damage (p<0.0001). Correlations were found between body weight, kidney volume, kidney weight, renal blood flow, histology, and serum levels of creatinine and urea. Our study provides the first evidence that treatment with PRP results in the deterioration of the kidney’s response to ischemia-reperfusion injury.
