Abstract
BACKGROUND AND AIM Rotator cuff tears emerge in approximately 30% of the population over 60 years of age. Arthroscopic surgical treatment of these lesions is the treatment of choice, however, despite the improved repair techniques, the rate of re-tears ranges between 11 and 94%. Therefore, researchers seek to improve the biological healing process through the use of different alternatives such as mesenchymal stem cells (MSCs). Our objective is to evaluate the efficacy of a Cellular Therapy Drug made from allogeneic stem cells derived from adipose tissue in a rat model of chronic rotator cuff injury. MATERIAL AND METHODS The supraspinatus lesion was created in 48 rats for subsequent suturing at 4 weeks. MSCs in suspension were added to 24 animals after suturing, and HypoThermosol-FRS® (HTS) to 24 animals as a control group. Histology (Åström and Rausing scale) and the maximum load, displacement and elastic constant of the supraspinatus tendon were analyzed in both groups 4 months after the repair. RESULTS No statistically significant differences were found in the histological score comparing the tendons treated with MSCs with respect to the tendons treated with HTS (P=.811) nor in the results of maximum load (P=.770), displacement (P=.852) or elastic constant (P=.669) of the tendon in both groups. CONCLUSIONS The addition of adipose-derived cells in suspension to the repair of a chronic cuff injury does not improve the histology or biomechanics of the sutured tendon.

Abstract
INTRODUCTION Radiofrequency electromagnetic fields (RF-EMFs) are one of the risk factors for male reproductive health and melatonin can be an ideal candidate for therapeutic development against RF-induced male fertility problems due to its antioxidant properties. The possible therapeutic role of melatonin in the destructive effects of 2100MHz RF radiation on rat sperm characteristics is investigated in the present study. METHODS Wistar albino rats were divided into four groups and the experiment continued for ninety consecutive days; Control, Melatonin (10mg/kg, subcutaneously), RF (2100MHz, thirty minutes per day, whole-body), and RF+Melatonin groups. Left caudal epididymis and ductus deferens tissues were placed in sperm wash solution (at 37°C) and dissected. The sperms were counted and stained. Measurements of the perinuclear ring of the manchette and posterior portion of the nucleus (ARC) were performed and the sperms were examined at an ultrastructural level. All of the parameters were evaluated statistically. RESULTS The percentages of abnormal sperm morphology were significantly increased with RF exposure, while the total sperm count was significantly decreased. RF exposure also showed harmful effects on acrosome, axoneme, mitochondrial sheath, and outer dense fibers at the ultrastructural level. The number of total sperms, sperms with normal morphology increased, and ultrastructural appearance returned to normal by melatonin administration. DISCUSSION The data showed that melatonin may be a beneficial therapeutic agent for long-term exposure of 2100MHz RF radiation-related reproductive impairments.

Abstract
PURPOSE This study was performed to evaluate the effect of ethanolic extract of Turkish propolis (EEP) on testicular ischemia/reperfusion (I/R) damage in rats in terms of biochemistry and histopathology, for the first time. METHODS A total of 18 male Sprague-Dawley rats were divided into three groups with six rats in each group: control, torsion/detorsion (T/D), and T/D+EEP (100mg/kg). Testicular torsion was performed by 720° rotating the left testicle in a clockwise direction. The duration of ischemia was 4h and orchiectomy was performed after 2h of detorsion. EEP was applied only once 30min before detorsion. Tissue malondialdehyde (MDA), total oxidant status (TOS) and total antioxidant status (TAS) levels were determined using colorimetric methods. Oxidative stress index (OSI) was calculated by proportioning tissue TOS and TAS values to each other. Tissue glutathione (GSH) and glutathione peroxidase (GPx) levels were determined using enzyme-linked immunosorbent assay (ELISA) kits. Johnsen's testicle scoring system was used for histological evaluation. RESULTS In the T/D group, it was determined that statistically significant decreasing in TAS, GSH, GPx levels and Johnsen score, and increasing in TOS, OSI and MDA levels (p<0.05) compared with control group. EEP administration statistically significantly restored this I/R damage (p<0.05). CONCLUSION This is the first study to show that propolis prevent I/R-induced testicular damage through its antioxidant activity. More comprehensive studies are needed to see the underlying mechanisms.

Abstract
INTRODUCTION Minocycline is a tetracycline with promising protective effects on different organs which are completely distinct from its antibacterial effects. METHODS To evaluate the effects of chronic administration of this agent on histological structure and sperm parameters of testes, forty adult male rats were randomly allocated into 2 equal groups I: control animals and II: treated animal that received 25mg/kg/day minocycline, orally. After 90 days of treatment, serum level of testosterone was assessed as well as sperm count, motility and morphology. Moreover, histological and histomorphometric evaluation of testes was performed including determination of height of the seminiferous germinal epithelium and perpendicular diameter of seminiferous tubules. Numbers of spermatogonia, primary spermatocytes, spermatids, Sertoli and Leydig cells were counted. Johnsen's scoring method was also performed. RESULTS Sperm parameters significantly improved in minocycline-treated animals. Moreover, number of germ cells in different stages of development significantly increased in treatment group as compared to control. This finding was associated with better Johnsen's score and thicker epithelium in seminiferous tubules. However, serum testosterone levels, Leydig and Sertoli cell count as well as tubular diameter did not show significant changes (p>0.05). DISCUSSION Chronic administration of minocycline is associated with improved spermatogenesis and sperm characteristics without affecting steroidogenesis in rats.

Abstract
OBJECTIVES In the present study, we aimed to investigate the effect of dexpanthenol on wound healing at the histopathological level on cavernous tissue. MATERIALS AND METHODS Forty-four Wistar albino rats weighing 220-250 g were used. The rats were randomly divided into four groups as Group B, Group S, Group LD, and Group SD. In Group B, the incision was not repaired and left to secondary healing. In Group S, the incision line was repaired with 5/0 polyglactin suture. In Group LD, 0.25 mg/kg dexpanthenol was applied subcutaneously below the repaired wound region once a day during 14 days. In Group SD, 500 mg dexpanthenol was applied intraperitoneally once a day during 14 days. RESULTS No fibrosis was observed in 8 (80%) rats in group SD. Fibrosis rates were significantly lower in Group SD compared to Group B, Group S, and Group LD (p = 0.013, p = 0.005, and p = 0.003, respectively). CONCLUSION Systemic dexpanthenol administration significantly decreased fibrosis in penile fracture model on rats.

Abstract
OBJECTIVES The aim of the study is to investigate the protective effect of taxifolin (3,5,7,3,4-pentahydroxy flavanone), a strong antioxidant, against testicular I/R injury in rats biochemically and histopathologically. MATERIALS AND METHODS 50mg/kg taxifolin was administered to taxifolin+testicular torsion-detorsion (TTTD, n-10) group of Albino Wistar male rats by oral gavage. Distilled water .5ml as a solvent was administered to testicular torsion-detorsion (TTD, n-10) and Healthy Control (SG, n-10) groups using the same method. An hour after the administration of taxifolin and distilled water, anaesthesia (ketamine 60mg/kg) was administered to all animal groups. TTD and TTTD group animals were subjected to testicular torsion at 720 degrees for four hours during anaesthesia. At the end of this period, testicular detorsion was applied and perfusion was allowed for four hours. Sham operation was applied to SG group. RESULTS Our biochemical experiment results showed that the amount of malondialdehyde (MDA) in testicular tissue of TTD group presented a significant increase compared to SG and TTTD groups whereas total glutathione (tGSH) and superoxide dismutase (SOD) levels decreased. In addition, while TTD group presented severe histopathological damage in germinal epithelium cell and seminiferous tubule, mild damage was observed in TTTD group. CONCLUSIONS The results of our experiment indicate that taxifolin could be useful in the treatment of testicular I/R damage.

Abstract
OBJECTIVES Although the association between 5 alpha reductase inhibitors used for the treatment of both androgenetic alopecia and benign prostatichy perplasia and their side effects is well established, the impact of dutasteride on testicular structure is not clear. To evaluate the alterations in spermatogenesis and serum FSH, LH, testosterone and dihydrotestosterone concentrations along with the oxidative status in testes and blood of the rats treated with daily dutasteride. METHODS A total of 18 male Sprague-Dawley rats have been divided into 2 groups as control (n=8) and dutasteride (n=10). After chronically administered, rats were sacrificed and their testes were harvested for histopathologica land biochemical evaluation. Johnsen's criteria were used to assess spermatogenesis. Serum hormone concentrations and levels of reactive oxygenspecies (ROS) in both testicular tissue and serum were measured by ECLIA and ELISA, respectively. Results were compared with Mann- Whitney U test. RESULTS DHT (7.35 ± 0.35 vs. 10.54 ± 0.95,p<0.001) and LH levels (0.32 ± 0.009vs. 0.43 ± 0.01,<0.001) were significantly lower in treatment group compared with controls where as testosterone levels were higher in dutasteride arm (3.41 ± 1.12 vs.1.52 ± 0.34, p<0.001). Johnsen score, serum FSH levels, serum and tissue ROS levels were similar betweenthe two groups. CONCLUSIONS According to our results, administration of dutasteride does not appear to modify spermatogenesis and oxidative burden in rats. Further investigations are required to confirm our findings.

Abstract
BACKGROUND Finding new agents for prevention and/or treatment of benign prostatic hyperplasia (BPH) especially from natural sources is a demanding field. OBJECTIVES This study aimed to evaluate the effect of black mulberry (BM) (Morus nigra) fruit hydroalcoholic extract on the establishment of BPH in rats. MATERIALS AND METHODS Forty-nine adult male rats were randomly assigned into 7 equal groups: I: Sham control (SC), a sham surgery was performed. II: positive control (PC), rats were castrated and received testosterone propionate, at 10mg/kg/day S.C. for BPH induction. III: comparative control (CC), BPH was induced and the rats received finasteride at 5mg/kg/day P.O. IV-VII: (T1-T4): BPH was induced and the rats received BM extract at 25, 50, 100 and 200mg/kg/day P.O. for 4 consecutive weeks. RESULTS Finasteride and/or BM extract especially at the two higher dosages, significantly affected prostate weight, prostatic index, percent of inhibition, serum and prostatic levels of dihydrotestosterone (DHT), serum prostate-specific antigen (PSA), antioxidant parameters of prostatic tissue as well as histopathological and histomorphometric parameters (epithelial thickness and acinar area) of prostate. CONCLUSIONS BM extract has protective effects against experimentally-induced BPH in rats with regard to histopathological and biochemical parameters which may be related to its antioxidant as well as DHT reducing properties in prostatic tissue.

Abstract
INTRODUCTION One of the most severe complications after esophaguectomy is anastomotic dehiscence. The use of collagen sponges could be an effective way to resolve this complication. Our objective was to perform an experimental model of esophageal anastomosis in rats to study these mechanisms. METHODS A total of 50 Sprague-Dawley rats were used divided into 2 groups, Tachosil® group (n=25) and control group (n=25). After the section of the abdominal esophagus a single-layer esophago-gastric anastomosis was performed reinforced with 1cm of Tachosil® wrapping the anastomosis in group 1. A functional study was performed using manometry as well as histopathological and immunohistochemical studies for angiogenic, fibrogenic and growth factors. RESULTS The mortality in our series was 8% in the collagen dressing group, compared to 36% in the control group. When esophageal manometry was performed, the dehiscence pressure was higher in the reinforced anastomosis, On microscopical analysis, in the collagen dressing group a profuse inflammatory reaction with abundant neutrophils and macrophages surrounded by a connective matrix with fibroblasts and blood vessels was observed, The expression of VEGF, FGF1 and FGF2 was noticeably higher in the collagen dressing group. CONCLUSIONS These results show that the application of collagen dressing facilitates tissue reparation phenomena, and therefore could be very useful as a reinforcement of esophago-gastric anastomosis to prevent dehiscence.

Abstract
INTRODUCTION It has been reported that varicocele might promote angiogenesis. However, it is not clearly identified how angiogenesis affect testicular morphology or spermatogenic activity. The objective of the study is to investigate the effect of spironolactone, as an angiogenesis inhibitor, on the ipsilateral testis morphology in left varicocele-induced rats. MATERIALS AND METHODS Twenty four adult (12-14 mo), male Wistar albino rats were randomly assigned to four groups (n=6, for each): 1. Control group, 2. Sham-operated group, 3. Experimental left varicocele group and, 4. Spironolactone (20mg/kg/day)-treated experimental left varicocele group. Histopathological findings in rat testis were investigated. RESULTS Microvessel density increased in varicocele group and spironolactone inhibited angiogenesis neither by antimineralocorticoid, nor by antiandrogenic effect. However, spermatogenesis impaired in spironolactone treated varicocele group. CONCLUSION Angiogenesis seems to be a protective process in varicocele. Spironolactone treatment, probably by inhibiting angiogenesis, impairs testicular morphology.

Abstract
INTRODUCTION Many studies have been conducted to determine the different effects that reaming or intramedullary nailing have on fracture healing, but there is no evidence in the literature of the effect of intramedullary reaming on osteogenesis. We performed a prospective study to analyse the effect of intramedullary reaming and nailing on the production of growth factors during the process of fracture healing in the femur of rats. MATERIAL AND METHODS A transverse mid-shaft non-comminuted femur fracture was produced in 64 rats; 34 rats did not receive any treatment, and a standardized surgical procedure was performed on 30 rats, by exposing the left knee, reaming the medullary canal from distal to proximal, and then fixing the fracture with a steel pin. The rats were sacrificed at the 24th hour, 4th, 7th and 15th days after the fracture. The amount of growth factors that appeared in the callus fracture was measured using histopathology studies. The primary categorical variables analysed were PDGFA, TGF2 and TGFβ-R2. These variables were analysed in each group at the different sacrifice times. RESULTS The results of the primary variables of the study, stratified by the time until sacrifice, showed no statistically significant differences. DISCUSSION Even if the presence of an intramedullary wire facilitates the fracture repair and the stabilising the bridge of bone between both edges of the fracture site, no evidence was found that reaming changes the expression of the growth factors studied (PDGFA, TGFβ-R2 and TGFβ2) during the callus formation in rats.

Abstract
INTRODUCTION Maintained acute occlusion followed by reperfusion of the superior mesenteric artery (SMA) in a few hours can trigger irreversible bowel damage. The aim of the study was to determine the changes in mesenteric flow measured by colour Doppler Ultrasound and correlating with histological lesions in an experimental model of ischaemia-reperfusion. METHOD AND MATERIAL Three groups of Sprague-Dawley 17 day-old rats were studied (control, ischemia and reperfusion). The model used was ischaemia-reperfusion over the SMA. Intra-abdominal ultrasound was then performed. The parameters recorded were: Maximum systolic velocity (MSV), pulsatility index (PI), resistance (RI) and systole-diastole (S/D). The histological variables were: intestinal lesion (Wallace/Keenan-Chiu scale), morphometrics (mean villus height [MVH]), and goblet cells. The Spearman (rs) correlation was used. RESULTS The MSV in the reperfusion group was 74.3 cm/s, the PI 7.33 and S/D 25.75 in the SMA, which were higher than the controls (41.35 cm/s; 3.12 and 12.45, respectively). A direct association (P<.01) was found between MSV, PI and S/D regarding: Wallace/Kennan scoring system (rs = 0.655; rs = 0.593; rs = 0.63) and the Chiu (rs = 0.569; rs = 0.522; rs = 0.47). While the correlation was the reverse (P<.01) when associated with the MVH (rs = -0,495; rs = -0,452; rs = -0,459) and goblet cells of the colon (rs = -0,525; rs = -0,45; rs = -0,518). CONCLUSIONS The reperfusion phase increased mesenteric flow expressed by the MSV and PI and could significantly predict the potential bowel damage at macroscopic and microscopic level.

Abstract
OBJECTIVE To determine whether a model of transient mass-type brain damage (MTBD) in the rat produces early release of neurospecific enolase (NSE) and protein S100B in peripheral blood, as an expression of the induced brain injury. DESIGN An experimental study with a control group. SETTING Experimental operating room of the Institute of Biomedicine (IBiS) of Virgen del Rocío University Hospital (Seville, Spain). PARTICIPANTS Fourteen adult Wistar rats. INTERVENTIONS Blood was sampled at baseline, followed by: MTBD group, a trephine perforation was used to insert and inflate the balloon of a catheter at a rate of 500 μl/20 sec, followed by 4 blood extractions every 20 min. Control group, the same procedure as before was carried out, though without trephine perforation. PRIMARY STUDY VARIABLES Weight, early mortality, serum NSE and S100B concentration. RESULTS Differences in NSE and S100B concentration were observed over time within the MTBD group (P<.001), though not so in the control group. With the exception of the baseline determination, differences were observed between the two groups in terms of the mean NSE and S100B values. Following MTBD, NSE and S100B progressively increased at all measurement timepoints, with r=0.765; P=.001 and r=0.628; P=.001, respectively. In contrast, the control group showed no such correlation for either biomarker. CONCLUSIONS Serum NSE and S100B concentrations offer an early indication of brain injury affecting the gray and white matter in an experimental model of mass-type MTBD in the rat.
