Does cabergoline administration affect endometrial VEGFR-2 expression in a rat model of ovarian hyperstimulation syndrome?

OBJECTIVE: To assess the effect of cabergoline on endometrial vascular endothelial growth factor receptor-2 (VEGFR-2) immunoexpression in an ovarian hyperstimulation syndrome (OHSS) rat model. MATERIAL AND METHODS: Twenty-one immature female Wistar rats were assigned into three groups: group 1, the control group; group 2, stimulated with gonadotropins to mimic OHSS; and group 3, in which an OHSS protocol was induced and thereafter treated with cabergoline (100 µg/kg/day). Body weight, ovarian volume, corpora lutea numbers, and endometrial VEGFR-2 expression were compared between the groups. RESULTS: Weight gain and ovarian volume were highest in the OHSS-placebo group, while cabergoline administration significantly reversed those effects (p = 0.001 and p = 0.001, respectively). VEGFR-2 stained cells were significantly lower in groups 2 and 3 compared to group 1 (p = 0.002). Although VEGFR-2 expression was lowest in group 3, the difference was not statistically significant. Corpora lutea numbers were also similar (p = 0.465). CONCLUSION: While successful implantation requires a vascularized receptive endometrium, impaired expression of VEGFR-2 and disrupted endometrial angiogenesis due to cabergoline administration may be associated with IVF failure in fresh OHSS cycles. The insignificant decrease in endometrial VEGFR-2 expression observed in this research needs to be investigated by further studies involving additional techniques such as immunoblotting and/or RT-PCR analyses.

Effect of Ankaferd Blood Stopper on muscle healing.

PURPOSE: Ankaferd Blood Stopper (ABS), which is a standardized mixture of herbal extracts obtained from five plants, has been proven as an efficient hemostatic agent and is still used in emergency situations. It is not known exactly if decreased bleeding has positive or negative effects on muscle healing and fibrosis, so the purpose of this study was to test the effect of ABS on muscle healing and morphology. METHODS: A total of 66 outbred Wistar rats were divided into three control and three experimental subgroups. In the experimental groups, ABS was sprayed on the cut surface of the soleus. In the control groups, a saline solution was sprayed on the cut surface of the soleus. Subgroups were euthanized after 2 weeks, 3 weeks and 4 weeks, respectively. In each subgroup, eight rats were used for the biomechanical study to determine muscle healing and three rats were used for the histopathological investigation. RESULTS: Although muscle strength in the control groups was lower than that of the experimental groups in early weeks, no differences were found between the control and the experimental groups at 4 weeks. CONCLUSIONS: ABS has no negative effect on muscle healing. We also observed that ABS accelerated muscle healing compared to the control group. ABS could be used in hemostasis of open fractures and elective orthopedic surgeries.

Cilostazol attenuates spinal cord ischemia-reperfusion injury in rabbits.

OBJECTIVE: The aim of this study was to evaluate the pretreatment effect of cilostazol on spinal cord ischemia-reperfusion injury. DESIGN: Prospective, interventional study. SETTING: Research laboratory, single institution. PARTICIPANTS: Twenty-four New Zealand white rabbits. INTERVENTIONS: Twenty-four rabbits were divided into 3 equal groups: group I (sham), group II (ischemia-reperfusion, control group), and group III (cilostazol, administered orally 30 mg/kg/day for 3 days before the surgery). Spinal cord ischemia was induced by clamping the aorta both below the left renal artery and above the iliac bifurcation for 30 minutes. Seventy-two hours postoperatively, the motor function of the lower limbs was evaluated in each animal according to the modified Tarlov score. Spinal cord and blood samples were taken for histopathologic and biochemical analyses at the 72nd hour of reperfusion. MEASUREMENTS AND MAIN RESULTS: All rabbits in the ischemia-reperfusion group (group II) showed severe neurologic deficits. The median (IQR) Tarlov scores postoperatively at 72 hours in groups I, II, and III were 5.0(-), 2.0(1.0), and 4.5(1.0), respectively. Administration of cilostazol resulted in a significant reduction in motor dysfunction when compared with the ischemia-reperfusion group (p<0.001). In the ischemia-reperfusion group, serum and tissue glutathione peroxidase and superoxide dismutase activity were significantly less compared with the sham group (group I) (p<0.05). Serum and tissue glutathione peroxidase and superoxide dismutase levels in the cilostazol-treated group (group III) were higher compared with the ischemia-reperfusion group (p<0.05). In the cilostazol-treated group, serum and tissue malondialdehyde levels were lower compared with the ischemia-reperfusion group (p<0.05). Histopathologic analysis found decreased neuronal injury in the cilostazol group when compared with the ischemia-reperfusion group (p< 0.05). CONCLUSIONS: This study showed that pretreatment with cilostazol significantly ameliorated neurologic functional outcome and attenuated neuronal histopathologic injury after transient aortic occlusion in rabbits.

Protective effects of Ankaferd blood stopper on aspirin-induced oxidative mucosal damage in a rat model of gastric injury.

The exposure of gastric mucosa to damaging factors, such as ethanol and some therapeutic drugs, produces pathological changes: inflammatory process, hemorrhagic erosions and even acute ulcers. Ankaferd blood stopper (ABS) comprises a standardized mixture of five different plant extracts. The purpose of our present investigations is to explain the participation of reactive oxygen species in acute gastric mucosal damage by acetylsalicylic acid (ASA) and the effects of new hemostatic agent ABS. Experiments were carried out on 23 male Wistar rats. To assess gastric mucosal damage, biochemical and histopathological data were used. The colorimetric assays were used to determine the malondialdehyde (MDA) and superoxide dismutase (SOD) activity. The level of myeloperoxidase (MPO) activity, the level of nitric oxide (NO) and the proinflammatory cytokine tumor necrosis factor-α (TNF-α) were measured by enzyme-linked immunosorbent assay technique. We demonstrated that the biological effects of ROS were estimated by measuring the tissue and plasma levels of MDA, the products of lipid peroxidation, as well as the activity of SOD and the scavenger of ROS produced by ASA in the experiment group. Moreover, it was found that MPO activity as well as NO and TNF-α levels also demonstrated significant improvement by ABS treatment. The pathogenesis of experimental ASA-induced mucosal damage in rat stomach includes the generation of ROS that seems to play an important role, due to the generation of lipid peroxides, accompanied by the impairment of antioxidative enzyme activity of cells. ABS appeared to attenuate the oxidative and inflammatory changes caused by ASA-induced gastric mucosal damage in rats.

Completely infarcted smooth muscle tumor of the placental membrane.

Non-trophoblastic tumor of the placenta is rare, and so is placental smooth muscle tumor. We report leiomyoma of the placental membrane, which was discovered on cesarean section. Histologically, the tumor was a benign leiomyoma with complete necrosis, and this finding was confirmed immunohistochemically. Only six cases of smooth muscle tumors of the placenta have been reported to date. This is the third report of leiomyoma involving the placental membrane.

Antiadhesive role of human amniotic fluid on peritoneal adhesion formation in a rat model. Experimental study.

OBJECTIVE: To determine the role of human amniotic fluid (HAF) in preventing or reducing postoperative adhesions. STUDY DESIGN: Uterine horn adhesion model was carried out in 24 female Wistar rats. The animals were randomized into 4 groups: (1) control, (2) Ringer's lactate, (3) whole HAF, and (4) HAF depleted from cells and proteins. Adhesion grade and histologic findings of adhesion-carrying tissues were evaluated and groups were compared according to these parameters. RESULTS: Rats treated with whole HAF had less adhesion grade when compared to the control group, but the difference was not statistically significant. On the other hand, centrifuged amniotic fluid treatment significantly reduced peritoneal adhesion grade, fibrosis and inflammation (p < 0.05). CONCLUSION: Whole HAF seems to have no beneficial effect on peritoneal adhesion formation, but HAF depleted of protein and cells does have a positive effect on reducing adhesion formation.

Effect of vitamin D on postoperative adhesion formation in a rat uterine horn adhesion model.

OBJECTIVE: To determine the role of vitamin D for preventing or reducing postoperative adhesions. STUDY DESIGN: The uterine horn adhesion model was carried out in 24 female Wistar rats. The animals were randomized into 4 groups: (1) control, (2) Ringer's lactate, (3) olive oil, and (4) vitamin D. Adhesion grade and histologic findings of adhesion-carrying tissues were evaluated, and groups were compared according to these parameters. RESULTS: Rats treated with vitamin D had less adhesion and lower inflammation grade when compared to the control and Ringer's lactate groups, and the results were statistically significant (p < 0.05). On the other hand, no difference was detected between the groups according to the fibrosis score. CONCLUSION: Vitamin D decreased postsurgical adhesion scores by both visual scores and histologic analyses in a rat model. Further experimental and clinical trials are required to confirm these results.

Splenic infarction following conventional open gastrectomy in patients with gastric malignancy: a CT-based study.

PURPOSE: The aim of this CT-based study was to investigate the frequency of splenic infarction (SI) following conventional open gastrectomy performed for gastric malignant neoplasms. METHODS: 20 patients who underwent subtotal or total gastrectomy, omentectomy, and D2 lymph node dissections preserving the spleen for gastric malignant neoplasms were retrospectively reviewed. Patients with postoperative CT scans within 3 months were enrolled in this study. CT imaging was performed with a 64-row multidetector CT scanner. Abdominal CT scan with precontrast and postcontrast portal phase images was performed on 19 of the patients, while pulmonary CT angiography was performed on 1 patient for chest pain. Second postoperative control abdominal CT images were also present for 3 of the 5 patients with SI. These examinations were also reviewed for the evolution of the SI's. RESULTS: SI was detected in 5 of the patients (25%) at a postoperative early stage. A single infarct area was detected in 4 of the 5 patients while two distinct infarct areas were present in one patient. The infarct areas in two patients disappeared on the second postoperative control CT. A decrease in the size of the SI area in 1 patient was also detected on the second postoperative control CT scan. CONCLUSION: The frequency of SI as a complication of abdominal surgeries tends to increase in CT-based studies. We have detected the highest frequency in the literature and suggest that SI, especially when accompanying D2 lymphadenectomy, should be included in the list of early stage gastrectomy complications.

Effect of liquid-based gel application during speculum examination on satisfactory level of smear examination.

PURPOSE: The aim was to evaluate the use of liquid-based gel during cytologic follow-up and the effect of liquid-based gel application during speculum examination on satisfactory level of smear. METHODS: A total of 1,999 patients were taken into the study. Patients were divided into two groups as gel-applied group and control group. Age and menopausal status of patients, and the physicians taking the smear (resident or specialist) were recorded. In control group, dry speculum was used for the collection of smear sample. All specimens were evaluated for correlation of the cytopathology, the number of "unsatisfactory" samples, and any secondary diagnoses. RESULTS: Assessment of smear satisfactoriness revealed that 2.2% (43) of them were unsatisfactory. Unsatisfactory smear ratio was significantly high in gel-applied group. Screening done by residents increased unsatisfactory result risk for about 5.5 times. Evaluation of effect of menopausal status on smear adequency revealed no difference between premenopausal and postmenopausal women. CONCLUSION: Cervical smear seems to be more accurate without gel application. Experience of the physician is also important. Water-based gel can be used in some women who experience overt pain during speculum examination, but these patients must be warned about unsatisfactory results and the need of repeat test.

To determine of the prevalence of Bacterial Vaginosis, Candida sp, mixed infections (Bacterial Vaginosis + Candida sp), Trichomonas Vaginalis, Actinomyces sp in Turkish women from Ankara, Turkey.

OBJECTIVE: To determine of the prevalence of Bacterial Vaginosis, Candida sp, mixed infections (Bacterial Vaginosis + Candida sp), Trichomonas Vaginalis, Actinomyces sp in Ankara, Turkey and analyze whether there is seasonal variation in these infectious agents. METHODS: A retrospective study on the results of 23298 cervical cytology examinations of patients which were performed in Fatih University Faculty of Medicine, Pathology Laboratory in Ankara, Turkey from January 2007 to July 2011. Patients were included in the study if a Pap smear was performed for any reason. RESULTS: The prevalence of Bacterial Vaginosis, Candida sp, mixed infections (Bacterial Vaginosis + Candida sp), Trichomonas Vaginalis, Actinomyces sp was 7.76%, 2.81%, 0.32%, 0.13%, and 0.27%, respectively A seasonal variation was not observed in the prevalence of any of the infectious agents (p>0.05). CONCLUSION: We conclude that cervical cytology is well suited for diagnosis of cervical infections. Bacterial vaginosis appears to be the predominant cause of vaginitis.

Mesenchymal stem cell therapy in necrotizing enterocolitis: a rat study.

We evaluated the potential therapeutic use of exogenous human bone marrow-derived mesenchymal stem cells (hBM-MSCs) in an experimental rat model of necrotizing enterocolitis (NEC). Thirty-six newborn Sprague-Dawley rats were randomly divided into three groups: NEC, NEC + hBM-MSC, and a control (control and control + hBM-MSC). NEC was induced by enteral formula feeding, exposure to hypoxia-hyperoxia, and cold stress. After NEC was induced, iron-labeled hBM-MSCs were administered by intraperitoneal injection. All pups were killed on the fourth day following injection, and the terminal ileum was excised for a histopathological and immunohistochemical evaluation. The pups in the NEC + hBM-MSC group showed significant weight gains and improvements in their clinical sickness scores (p < 0.01). Bowel damage severity observed in the histopathological evaluation was significantly lower in the NEC + hBM-MSC group than that in the NEC group (p = 0.012). The number of MSCs homing to the bowel was significantly higher in the NEC + hBM-MSC group than that in the control + hBM-MSC group. In conclusion, this is the first study that has evaluated the effectiveness of hBM-MSCs in a neonatal rat NEC model. MSCs reduced histopathological damage significantly.

Protective effects of caffeic acid phenethyl ester (CAPE) on intestinal damage in necrotizing enterocolitis.

OBJECTIVE: To determine the preventative effect of caffeic acid phenethyl ester (CAPE) in necrotizing enterocolitis (NEC) in an experimental rat model of NEC. MATERIALS AND METHODS: Thirty newborn Sprague-Dawley rats were randomly divided into three groups; as NEC, NEC + CAPE and control. NEC was induced by enteral formula feeding, subjected to hypoxia-hyperoxia and cold stress. Pups in the NEC + CAPE group were treated with CAPE at a dose of 30 mg/kg daily by intraperitoneal route from the first day to the end of the study. All pups were executed on the fourth day. Proximal colon and ileum were allocated for histopathologic and biochemical evaluation, including xanthine oxidase (XO), total antioxidant status (TAS), total oxidant status (TOS), malonaldehyde (MDA) and myeloperoxidase (MPO) activities. RESULTS: The pups in the NEC + CAPE group had better histopathologic and apoptosis evaluations (TUNEL and caspase-9) and the severity of bowel damage was significantly lower in the NEC + CAPE group compared to the NEC group (P < 0.01). The clinical sickness scores and body weight in the NEC + CAPE group was significantly better compared to the NEC group (P < 0.05). Tissue MDA, MPO, XO levels and TOS were remarkably reduced in the NEC + CAPE group, however, TAS was significantly increased in the NEC + CAPE group (P < 0.05). CONCLUSION: Treatment with CAPE reduces the intestinal damage in NEC.

Differentially regulated ADAMTS1, 8, 9, and 18 in pancreas adenocarcinoma.

INTRODUCTION: Despite recent diagnostic and therapeutic improvements, pancreas cancer remains one of the highly lethal cancers. The extracellular matrix (ECM) is a physiological barrier that limits the spread of cancer cells into surrounding tissues and distant organs. Disintegrin and metalloprotease with thrombospondin motifs (ADAMTS) is a family of 19 proteases, which is involved in various biological processes such as ECM remodelling and anti-angiogenesis. AIM: To investigate the expression of ADAMTS1, 8, 9, and 18 proteinases in pancreas adenocarcinoma and its nodal metastasis. MATERIAL AND METHODS: The immunostaining status of ADAMTS1, 8, 9, and 18 were investigated in formalin-fixed paraffin-embedded samples of 25 patients who underwent pancreaticoduodenectomy for an adenocarcinoma located at the head of the pancreas. RESULTS: In semi-quantitive grading pathologically, ADAMTS1, 8, 9, and 18 were found to be highly stained in all cancerous pancreas samples compared with normal pancreas. In addition, the immune positivity of ADAMTS1, 9, and 18 was found to be higher in metastatic lymph nodes than in non-metastatic lymph tissue. Tumour size was correlated with ADAMTS9 and 18 expressions in cancerous pancreas. CONCLUSIONS: According to the data obtained from the study, we suggest that these four ADAMTSs may have significant roles in the tumorigenesis and nodal spread of pancreas adenocarcinoma.

Effects of quercetin on methotrexate-induced nephrotoxicity in rats.

OBJECTIVE: This experimental study was conducted to elucidate the possible protective/therapeutic effects of quercetin against methotrexate (Mtx)-induced kidney toxicity with biochemical and histopathological studies. METHODS: Twenty-four adult male rats were randomly divided into four groups, as follows: control group (saline intraperitoneally (i.p.), 9 days), Mtx group (20 mg/kg i.p., single dose), Mtx + quercetin group (50 mg/kg quercetin was orally administered 2 days before and 6 days after Mtx administration) and only quercetin group (50 mg/kg oral, 9 days). Structural changes were evaluated by hematoxylin-eosin and periodic acid-Schiff stainings. Apoptotic changes were investigated by terminal deoxynucleotidyl transferase dUTP nick end labeling assay and caspase-3 antibody. Superoxide dismutase (SOD) and malondialdehyde (MDA) levels were measured in tissue and plasma samples. RESULTS: Mtx compared with the control group, there was significant increase in nephrotoxic tissue damage findings, in addition to apoptotic index (APOI) and caspase-3 expression ( p < 0.05). Mtx + quercetin group revealed significantly lower histopathological damage and APOI and caspase-3 expression decreased when compared to Mtx group. MDA levels were increased in Mtx group compared to others, and by the use of quercetin, this increase was significantly reduced. SOD levels were higher in Mtx group than others. This increase was evaluated as a relative increase arising from oxidative damage caused by Mtx. CONCLUSION: As a result, Mtx administration may involve oxidative stress by causing structural and functional damage in kidney tissue in rats. Quercetin reduced the Mtx-induced oxidative stress through its antioxidant properties and so quercetin may be promising to alleviate Mtx-induced renal toxicity.

Paratesticular Fibrous Pseudotumors.

Paratesticular fibrous pseudotumors (PFPs) are rare pathologies with quite wide and variable topographic-morphological features. It is difficult to distinguish PFPs from malignant masses. Treatment can be done by resection of the mass. We reported a young patient's findings about this rare pathology.

Effects of curcumin on ovarian ischemia-reperfusion injury in a rat model.

Ischemia-reperfusion injury is a significant problem following reperfusion treatment for ovarian torsion. It is generally caused by reactive oxygen species-induced damage. Antioxidant agents, such as curcumin, may protect ovaries from this adverse effect. The aim of the present randomized, controlled study was to evaluate the short-term protective effect of curcumin on a rat model of ovarian ischemia-reperfusion injury. A total of 30 female Wistar albino rats, weighing 160-230 g, were divided into 2 groups depending upon the time of unilateral, left ovary ischemia/reperfusion (group 1, 2 h ischemia/2 h reperfusion and group 2, 4 h ischemia/4 h reperfusion). These groups were subdivided into 3 subgroups (sham, control and curcumin). The sham subgroups were not subjected to ischemia/reperfusion. Control and curcumin subgroups were performed under ischemia for 2 h plus 2 h reperfusion or 4 h ischemia plus 4 h reperfusion. Curcumin, 200 mg/kg, was intraperitoneally administered simultaneously with reperfusion to the curcumin subgroups. Serum nitric oxide (NO), NO synthase (NOS), xanthine oxidase (XO), total antioxidant status (TAS), total oxidant status (TOS) and histological scores were measured and compared between subgroups. For group 1, no significant differences were observed between NO, NOS, XO, TAS or TOS. The left ovary histological grade was significantly higher in the control and curcumin subgroups compared with the sham subgroup (P=0.036). For group 2, TOS was significantly higher in the control group compared with the sham and curcumin groups (P=0.023). However, TAS was also significantly higher in the control subgroup compared with the other 2 subgroups (P=0.005). Left ovary histological grade was significantly higher in the control and curcumin subgroups compared with the sham subgroup (P=0.038). No significant differences were observed between NO, NOS or XO between the group 2 subgroups. The results showed that curcumin exerted no major significant protective effect on ischemia-reperfusion injury in the rat ovary.

Corneal melanosis successfully treated using topical mitomycin-C and alcohol corneal epitheliectomy: a 3-year follow-up case report.

We report a case of primary acquired corneal melanosis without atypia associated with corneal haze in a patient with a history of limbal malignant melanoma and the effect of mitomycin-C. A 75-year-old woman with a history of limbal malignant melanoma presented with loss of vision in right eye. Corneal examination showed a patchy melanotic pigmentation with a central haze. Topical mitomycin-C improved visual acuity and corneal haze. However, the pigmented lesions persisted, and they were removed with alcohol corneal epitheliectomy. Histopathological examination demonstrated primary acquired melanosis without atypia. The lesions were successfully removed, and there were no recurrences during the follow-up period of 36 months. The association of conjunctival and corneal melanosis without atypia is a rare condition. In addition, co-existence of central corneal haze and melanosis may decrease visual acuity. Topical mitomycin-C and alcohol corneal epitheliectomy can be useful treatments in this condition.

Effect of Hypericum perforatum on intraperitoneal adhesion formation in rats.

INTRODUCTION: The aim of this study was to evaluate the efficacy of Hypericum perforatum for prevention of adhesion formation in rats. MATERIAL AND METHODS: Twenty-four female wistar rats underwent left uterine horn adhesion model. Rats were randomised into 4 groups. Group 1 (Control): Closure of abdominal incision without any agent administration. Group 2: Closure of incision after administration of intraperitoneal (i.p.) Ringer's lactate solution. Group 3: Closure of incision after administration of i.p. olive oil (diluent of H. perforatum). Group 4: Hypericum perforatum extract (Ecodab(®)) was administered i.p. before the closure of incision. Fourteen days later, relaparatomy was performed and surgical adhesion scores, inflammation and fibrosis scores were noted. Groups were compared according to these scores. RESULTS: There was statistical significant difference between ringer's lactate group and olive oil group according to surgical adhesion score (p = 0.009). However, groups were not different according to inflammation and fibrosis scores (p > 0.05). CONCLUSIONS: Despite antiinflammatory, antioxidants and antimicrobial properties of H. perforatum, our results revealed no positive effect of H. perforatum on the prevention of intraperitoneal adhesion formation.

Comparison of the effects of different percutaneous tracheotomy techniques on acute tracheal trauma.

AIM: As it can easily be performed at the bedside with minimal morbidity, percutaneous dilatational tracheotomy (PDT) is preferred over surgical tracheotomy. The aim of this study is to compare the effects of different PDT techniques on posterior tracheal wall injury. MATERIALS AND METHODS: The study was conducted at the Gazi University Laparoscopy Training Center after approval was granted by the ethics committee. After sedation with xylazine/ketamine, electrocardiography, peripheral oxygen saturation, and blood pressure were monitored. Propofol was used to achieve the desired level of sedation during the procedure. There were 16 pigs, randomly allocated into 4 groups. Multiple, single, forceps, and twist dilator techniques were performed in groups I, II, III, and IV, respectively. At the end of the course all pigs were sacrificed and tracheas were harvested for macroscopic and histopathological evaluation. RESULTS: Macroscopic evaluation revealed erythematous/hemorrhagic and ulcerative lesions on the posterior wall of all samples. Histopathological injury was observed in all samples and was similar in all groups. Procedural time was significantly longer in group I than in all other groups (P < 0.05). CONCLUSION: Although the results are conflicting, bronchoscopy-aided PDT is believed to reduce complications. In our study, PDTs were performed without bronchoscopy, and posterior wall injury was observed in all samples. Therefore, we suggest using bronchoscopy to reduce procedure-related complications and improve patient safety during PDT.

Assessment of the efficacy of Ankaferd blood stopper on the prevention of postoperative pericardial adhesions.

OBJECTIVES: Ankaferd has been used as a blood-stopping agent and it may also have an anti-inflammatory effect. We investigated the efficacy of Ankaferd in preventing postoperative pericardial adhesions in an experimental rabbit model. METHODS: Sixteen New Zealand white rabbits were used and categorised into two groups: an Ankaferd and a control group. The Ankaferd group of rabbits was treated with a sponge impregnated with Ankaferd solution, which was applied over the abraded epicardium. A sponge impregnated with 0.9% isotonic NaCl solution was applied to the control group using the same protocol. Scores for adhesion and visibility of coronary vessels were graded by macroscopic examination, and pericardial tissues were analysed microscopically in terms of inflammation and fibrosis. RESULTS: In the Ankaferd group, the adhesion scores were significantly higher than in the control group (p = 0.007). When the groups were compared according to the prevalence of fibrosis and degree of inflammation, the Ankaferd group was found to be statistically significantly different from the control group in terms of prevalence of fibrosis (p = 0.028). CONCLUSIONS: Topical application of Ankaferd to prevent postoperative pericardial adhesions increased adhesion and fibrosis scores.
