Abstract
One of the most prevalent disorders of the urinary system is urinary tract infection, which is mostly brought on by uropathogenic Escherichia coli (UPEC). The objective of this study was to evaluate the regenerative therapeutic and antibacterial efficacy of PRP for induced bacterial cystitis in dogs in comparison to conventional antibiotics. 25 healthy male mongrel dogs were divided into 5 groups (n = 5). Control negative group that received neither induced infection nor treatments. 20 dogs were randomized into 4 groups after two weeks of induction of UPEC cystitis into; Group 1 (control positive; G1) received weekly intravesicular instillation of sodium chloride 0.9%. Group 2 (syst/PRP; G2), treated with both systemic intramuscular antibiotic and weekly intravesicular instillation of PRP; Group 3 (PRP; G3), treated with weekly intravesicular instillation of PRP, and Group 4 (syst; G4) treated with an intramuscular systemic antibiotic. Animals were subjected to weekly clinical, ultrasonographic evaluation, urinary microbiological analysis, and redox status biomarkers estimation. Urinary matrix metalloproteinases (MMP-2, MMP-9) and urinary gene expression for platelet-derived growth factor -B (PDGF-B), nerve growth factor (NGF), and vascular endothelial growth factor (VEGF) were measured. At the end of the study, dogs were euthanized, and the bladder tissues were examined macroscopically, histologically, and immunohistochemically for NF-κB P65 and Cox-2. The PRP-treated group showed significant improvement for all the clinical, Doppler parameters, and the urinary redox status (p < 0.05). The urinary MMPs activity was significantly decreased in the PRP-treated group and the expression level of urinary NGF and VEGF were downregulated while PDGFB was significantly upregulated (p < 0.05). Meanwhile, the urinary viable cell count was significantly reduced in all treatments (P < 0.05). Gross examination of bladder tissue showed marked improvement for the PRP-treated group, expressed in the histopathological findings. Immunohistochemical analysis revealed a marked increase in Cox-2 and NF-κB P65 in the PRP-treated group (P < 0.05). autologous CaCl2-activated PRP was able to overcome the bacterial infection, generating an inflammatory environment to overcome the old one and initiate tissue healing. Hence, PRP is a promising alternative therapeutic for UPEC cystitis instead of conventional antibiotics.

Abstract
BACKGROUND Ischemia-reperfusion (I/R) injury is a major cause of surgical skin flap compromise and organ dysfunction. Platelet-rich plasma (PRP) is an autologous product rich in growth factors, with tissue regenerative potential. PRP has shown promise in multiple I/R-induced tissue injuries, but its effects on skin flap injury remain unexplored. METHODS We evaluated the effects of PRP on I/R-injured skin flaps, optimal timing of PRP administration, and the involved mechanisms. RESULTS PRP protected against I/R-induced skin flap injury by improving flap survival, promoting blood perfusion and angiogenesis, suppressing oxidative stress and inflammatory response, and reducing apoptosis, at least partly via deactivating Janus kinase (JAK)-signal transducers and activators of transcription (STAT) signalling pathway. PRP given before ischemia displayed overall advantages over that given before reperfusion or during reperfusion. In addition, PRP pretreatment had a stronger ability to reverse I/R-induced JAK/STAT activation and apoptosis than AG490, a specific inhibitor of JAK/STAT signalling. CONCLUSIONS This study firstly demonstrates the protective role of PRP against I/R-injured skin flaps through negative regulation of JAK/STAT activation, with PRP pretreatment showing optimal therapeutic effects.

Abstract
The widespread use of silver in various forms raises concerns about its potential adverse effects. Silver nanoparticles (AgNPs) can enter the brain and subsequently induce neurotoxicity. As a source of diverse growth factors and for its cytoprotective properties, platelet-rich plasma (PRP) has received considerable attention in regenerative medicine. Our aim was to estimate the toxic effects of AgNPs on the rat brain and assess the possible protective effects of PRP against AgNPs induced neurotoxicity. A total of 40 adult male rats were divided into four groups (n = 10), namely the control, AgNPs, AgNPs+PRP, and auto-recovery groups. AgNPs were given intraperitoneally (i.p.) at a 10 mg/kg dose.bw daily for 28 days. PRP was given (a day after AgNPs treatment) i.p. at a dose of 0.5 mL/kg.bw twice weekly for 3 weeks. Rats in the auto-recovery group were left without treatment for 3 weeks after AgNP toxicity. Serum and brain tissue samples were collected for assessment of proinflammatory cytokines, oxidative stress markers, as well as the expression levels of apoptotic markers. Brain histopathological and immunohistochemistry examinations were done. AgNPs significantly increased oxidative stress markers and proinflammatory cytokines, decreased antioxidant defense markers, and induced apoptosis and histopathological brain injuries. However, PRP treatment restored brain oxidant/antioxidant balance, attenuated the inflammatory state, prevented apoptosis, and improved the brain histopathological lesions induced by AgNPs, with no significant improvements shown by auto-recovery group. Our data provided a novel protective effect for PRP against AgNPs-induced neurotoxicity due to its antioxidant, anti-inflammatory, and antiapoptotic effects.

Abstract
Tendinopathies are common disabling conditions in equine and human athletes. The etiology is still unclear, although reactive oxygen species (ROS) and oxidative stress (OS) seem to play a crucial role. In addition, OS has been implicated in the failure of tendon lesion repair. Platelet-rich plasma (PRP) is rich in growth factors that promote tissue regeneration. This is a promising therapeutic approach in tendon injury. Moreover, growing evidence has been attributed to PRP antioxidant effects that can sustain tissue healing. In this study, the potential antioxidant effects of PRP in tenocytes exposed to oxidative stress were investigated. The results demonstrated that PRP reduces protein and lipid oxidative damage and protects tenocytes from OS-induced cell death. The results also showed that PRP was able to increase nuclear levels of redox-dependent transcription factor Nrf2 and to induce some antioxidant/phase II detoxifying enzymes (superoxide dismutase 2, catalase, heme oxygenase 1, NAD(P)H oxidoreductase quinone-1, glutamate cysteine ligase catalytic subunit and glutathione, S-transferase). Moreover, PRP also increased the enzymatic activity of catalase and glutathione S-transferase. In conclusion, this study suggests that PRP could activate various cellular signaling pathways, including the Nrf2 pathway, for the restoration of tenocyte homeostasis and to promote tendon regeneration and repair following tendon injuries.

Abstract
Oxymetholone is one of the anabolic steroids that has widely been used among teenagers and athletes to increase their muscle bulk. It has undesirable effects on male health and fertility. In this study, the therapeutic effects of platelet-rich plasma (PRP) on oxymetholone-induced testicular toxicity were investigated in adult albino rats. During the experiments, 49 adult male albino rats were divided into 4 main groups: Group 0 (donor group) included 10 rats for the donation of PRP, Group I (control group) included 15 rats, Group II included 8 rats that received 10 mg/kg of oxymetholone orally, once daily, for 30 days, and Group III included 16 rats and was subdivided into 2 subgroups (IIIa and IIIb) that received oxymetholone the same as group II and then received PRP once and twice, respectively. Testicular tissues of all examined rats were obtained for processing and histological examination and sperm smears were stained and examined for sperm morphology. Oxymetholone-treated rats revealed wide spaces in between the tubules, vacuolated cytoplasm, and dark pyknotic nuclei of most cells, as well as deposition of homogenous acidophilic material between the tubules. Electron microscopic examination showed vacuolated cytoplasm of most cells, swollen mitochondria, and perinuclear dilatation. Concerning subgroup IIIa (PRP once), there was a partial improvement in the form of decreased vacuolations and regeneration of spermatogenic cells, as well as a reasonable improvement in sperm morphology. Regarding subgroup IIIb (PRP twice), histological sections revealed restoration of the normal testicular structure to a great extent, regeneration of the spermatogenic cells, and most sperms had normal morphology. Thus, it is recommended to use PRP to minimize structural changes in the testis of adult albino rats caused by oxymetholone.

Abstract
Background Loss of islet survival and function, caused by native niche disruption and oxidative stress induction during mechanical and enzymatic isolation, limits the effectiveness of islet transplantation. Reconstitution of islet microenvironment, vascularization, and decreased oxidative stress with biomaterials may improve islet quality and graft outcomes. We investigated effects of two biomaterials, platelet-rich plasma and pancreatic islets homogenate combination on islet recovery and quality by evaluating in vitro islet survival, secretory function, and oxidative stress parameters and assessing in vivo transplantation outcomes. Methods In vitro, islet viability and secretory function of isolated islets were assessed after 24 h and 72 h incubation with biomaterials. Also, oxidative stress markers were measured once after isolation and 24 h after incubation with biomaterials. For evaluating in vivo effects, cultured islets for 24 h were transplanted into subscapular space of diabetic rat kidney, and outcomes were analyzed by measuring serum glucose and insulin concentrations, glucose tolerance test, level of oxidative parameters, and pancreatic gene expression. Results Treating islets with biomaterials significantly increased their viability and secretory function, reduced MDA level, and elevate SOD and CAT activity. Decreased level of glucose and MDA improved insulin level, increased SOD activity, and also enhanced pdx1 and insulin gene expression in diabetic rats after islet transplantation. Conclusions Biomaterials used in the present study should be consider as beneficial materials for increasing islet transplantation outcome. These materials may hamper transplantation limitation to some extent.

Abstract
Platelet concentrates (PCs) are widely used in regenerative medicine; as it is produced from freeze–thawing PC, platelet lysate (PL) has a longer shelf life. The thrombotic risk of PL therapy needs to be explored since PL and PC contain cytokines that contribute to platelet aggregation and thrombus formation. Whole blood samples of 20 healthy subjects were collected; PL was produced from PCs with expired shelf life through freeze–thawing. The direct mixing of PL with platelet-rich plasma (PRP) or whole blood was performed. In addition, rotational thromboelastometry (ROTEM) was used to investigate whether PL enhanced coagulation in vitro; the effects of fibrinogen depletion and anticoagulants were evaluated to prevent hypercoagulation. The results showed that PL induced platelet aggregation in both PRP and whole blood. In ROTEM assays, PL was shown to cause a significantly lower clotting onset time (COT) and clot formation time (CFT), and a significantly greater α angle and maximum clot firmness (MCF). Compared with the controls, which were 1:1 mixtures of normal saline and whole blood, fibrinogen depletion of PL showed no significant difference in CFT, α angle and MCF. Moreover, heparin- and rivaroxaban-added PL groups demonstrated no clot formation in ROTEM assays. Platelet lysate-induced hypercoagulability was demonstrated in vitro in the present study, which could be prevented by fibrinogen depletion or the addition of an anticoagulant.

Abstract
BACKGROUND The number of cases of male infertility is steadily growing every year, and therefore it is necessary to develop new methods for the diagnosis and treatment of this disease. It is known that plasma enriched with platelets, the α-granules of which contain growth factors, possesses high regenerative activity; therefore, we can expect positive results from its use for the restoration of spermatogenic epithelium. OBJECTIVE Morphological assessment of spermatogenesis after local β-irradiation with a dose of 8 Gy and the introduction of growth factors. MATERIAL AND METHODS Wistar rats (n=135) were divided into groups: I - Control, II - 8IR, III - 8IR+LP-PRP+IGF, IV - 8IR+LP-PRP, and V - LP-PRP. Spermatogenesis in animals of groups II, III, and IV was inhibited by a single local irradiation with 8 Gy electrons. Then, for 11 weeks, LP-PRP was injected intraperitoneally to rats III and IV, and in group III - additionally IGF-1. The testes were examined by light microscopy, computer morphometry, micro-CT, and Western blotting. RESULTS After irradiation, a decrease in spermatogenic epithelium and the number of germ cells was observed up to sub- and total germinal aplasia, fibrosis and an increase in the expression of caspase-3. Against the background of LP-PRP+IGF administration, the decrease in the proportion of germ cells (hypospermatogenesis) was less pronounced. CONCLUSION The introduction of growth factors and other biologically active substances released from the α-granules of LP-PRP platelets leads to a delayed decrease in the quantitative and qualitative indicators of spermatogenesis, and the additional administration of IGF-1 enhances the regenerative processes that counteract the development of the effects of electron irradiation with a dose of 8 Gy.

Abstract
Leukocyte-poor platelet-rich plasma (LP-PRP) has a potential influence on tissue regeneration by stimulating proliferation and differentiation of progenitor cells.The aim of this work is morphological assessment of spermatogenesis under the influence of growth factors after electron irradiation. MATERIALS AND METHODS Experimental animals (n = 135) were divided into 5 groups: I - control (n = 10); II - 2IR (n = 35; 2 Gy); III - 2IR + LP-PRP + IGF-1 (n = 30); IV - 2IR + LP-PRP (n = 30); V - LP-PRP (n = 30). RESULTS Electron irradiation reduces the number of germ cell in comparison with the control group. After injection of LP-PRP + rhIGF-1 significantly increased the number of germ cells, Sertoli and Leydig cells, height of germinal epithelium, area and diameter of seminiferous tubules. CONCLUSION LP-PRP + rhIGF-1 has a normalizing effect on structural and functional disorders of the testis caused by electron irradiation.

Abstract
Testicular torsion is an emergency urological disease, and the treatment is immediate surgery. Despite emergency surgery, testicular damage may occur due to reperfusion. Therefore, a medical treatment to prevent this damage may be a rational idea. We aimed to evaluate the protective effect of oltipraz in testicular ischaemia/reperfusion damage. Twenty-eight Wistar-Albino rats were randomly divided into four groups. In ischaemia/reperfusion group, testicular torsion was executed, and orchiectomy was done 4 hr after detorsion with no treatment. Second group performed torsion; intraperitoneal 50 mg/kg oltipraz was applied 30 min before detorsion, and orchiectomy was performed 4 hr after detorsion. Third group applied torsion; intraperitoneal 150 mg/kg oltipraz was applied 30 min before detorsion, and orchiectomy was performed 4 hr after detorsion. Last one was the sham group. We evaluated tissue malondialdehyde (MDA), transforming growth factor-β1 (TGF-β1), superoxide dismutase (SOD), reduced glutathione (GSH) and Johnsen testicular biopsy score. There was a significant decrease in TGF-β1, GSH and MDA values in oltipraz treatment groups compared with ischaemia/reperfusion group. Oltipraz treatment has significant protective effect in testicular ischaemia/reperfusion damage. However, more clinical studies are needed to demonstrate appropriate dose and its effects.

An investigation of the effects of amniotic fluid on experimental ischemia/reperfusion damage in rat testes. J Pediatr Urol 2021; 17:761.e1-761.e6. [PMID: 34518124 DOI: 10.1016/j.jpurol.2021.08.006] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Revised: 07/18/2021] [Accepted: 08/06/2021] [Indexed: 11/26/2022]
Abstract
INTRODUCTION Various agents have been tested as preventive treatments for ischemia/reperfusion (IR) damage. In this study, we have investigated for the first time in the literature the efficacy of injection of amniomax (AMX) into testicular parenchyma, which is a commercial medium of rat amniotic fluid, in preventing testicular IR damage related to testicular torsion. OBJECTIVE This study aims to evaluate whether or not amniomax has an effect on experimental IR damage in rat testes using biochemical and histopathological methods based on data in the literature. Even if testicular torsion is repaired surgically in early term injury because of de IR damage still occurs. Is it possible to reduce the ischemia reperfusion injury with amniotic fluid and increase the success of treatment? STUDY DESIGN 40 male Wistar albino rats were included. Four groups were formed with 10 rats in each group: Sham, Ischemia/Reperfusion (IR), injection 1 min before detorsion (AMX-BD), injection 1 min after detorsion (AMX-AD). Total Oxidant Status (TOS) and Oxidative Stress Index (OSI) were computed for oxidative stress, and Total Antioxidant Status (TAS) levels were computed for the antioxidant system, for both serum and tissue. Necrosis and microcalcification levels were assessed in the evaluation of testicular histology. P < 0.05 was considered statistically significant. RESULTS AMX-AD group has low necrosis degree than IR, Mean serum and tissue levels of TAS, TOS, and OSI parameters were respectively determined as; for TAS: 0.64 ± 0.11 and 0.96 ± 0.25 mmol Trolox Equivalent/L; for TOS: 6.71 ± 0.87 and 9.40 ± 1.03 μmol H2O2 equivalent/L; for OSI: 11.94 ± 3.74 and 10.70 ± 4.23 arbitrary unit. DISCUSSION Our study has investigated for the first time in the literature the efficacy of amniotic fluid in preventing testicular IR damage, and used amniomax (AMX) for this purpose. The limitation of our study may be the small number of rat in the groups. CONCLUSION We think an injection after detorsion is more favorable considering that the AMX-AD group demonstrated significantly lower levels of TOS in serum and tissue and OSI in serum, and significantly higher serum levels of TAS compared to the AMX-BD group, as well as the fact that the morphological protection effect was only observed for injections performed immediately after detorsion.

Abstract
INTRODUCTION Testis torsion is a urological emergency and a serious situation that may cause testis atrophy, testicular dysfunction and infertility due to ischaemia/reperfusion(I/R) injury even with early intervention. OBJECTIVE To assess the protective effect of dexpanthenol administered intratesticular after detorsion against testis I/R injury. STUDY DESIGN Twenty-seven rats were randomly divided into 3 groups containing 9 rats each. The 1st group comprised the sham group with no procedure performed. The 2nd group had only torsion applied, while the 3rd group had torsion + dexpanthenol applied. Rats had 720° clockwise rotation applied to the left testis. After 2 h of ischaemia, testes were de-torsioned and the dexpanthenol group had 500 mg/kg dexpanthenol administered intratesticular after detorsion. After 4 h of reperfusion, rats had blood samples taken and orchiectomy was performed for histologic assessment. RESULTS A significant difference was detected in all parameters [necrosis(p:<0.001), Cosentino grade (p < 0.001), congestion (p:0.005), fibrosis (p:<0.001), interstitial oedema (p:0.017), JTBS score (p:<0.001), apoptosis (p < 0.001) and testosterone levels (p:0.006)] when the sham, torsion, and torsion + dexpanthenol groups were compared. Significant differences were observed for fibrosis (p:0.010), Cosentino score (p < 0.001), JTBS score (p:<0.001), apoptosis (p:0.001) and total testosterone levels (p:0.013) when torsion and torsion + dexpanthenol groups were compared. The torsion + dexpanthenol group was identified to have more preservation of testis function observed histologically and hormonally compared to the torsion group. DISCUSSION Dexpanthenol is used in many areas due to both epithelizing and antioxidant effects and lack of clear side effects. In spite of use of many chemical and biological agents to protect against testis I/R injury, none have entered routine use. This study showed that dexpanthenol, which can be easily injected intratesticular during detorsion surgery, has protective effect against histological and functional injury that may develop linked to testis I/R injury. The main limitations of the study are short duration of follow-up due to being a rat experiment and lack of comparison of lipid peroxidation products. CONCLUSION This study identified that dexpanthenol with clinically easy use by intratesticular injection after detorsion during surgery had a protective effect against histological and functional injury that will develop linked to I/R injury in the testis.

Abstract
This study was conducted on forty adult rats divided into four groups: Group I (control) that is divided into subgroups A, B, and C and Group II (methotrexate (MTX)-treated); the rats were injected intraperitoneally with MTX at a dose of 1 mg/kg/week, for 8 weeks. Group III (MTX-Se co-treated) was injected with MTX like Group II plus an oral administration of selenium at a dose of 10 μg/kg b.w/day, for 8 weeks. Group IV (MTX-PRP co-treated), rats were injected intraperitoneally with MTX like Group II plus platelet-rich plasma (PRP) injection under the scrotum, three times with 2-week intervals (volume-0.1 ml per injection) and euthanized after 8 weeks. Histological, immunohistochemical, and genetic expression using qPCR and western blotting technique were conducted. There was improvement in histological structure of testes in most specimens of Group IV. The latter group revealed a significant decrease in Bax and an increase in Bcl-2. The regeneration of testicular tissue was more observed in Group IV as measured by an increase in mean number of PCNA. Moreover, Group IV revealed an increased genetic level of FSCN3, GCNF, UBQLN3, and DAZL. Both MTX-Se and MTX-PRP have an anti-inflammatory effect as measured by a reduction in NF-κb. The anti-oxidative effect of selenium and PRP was noticed by a decrease in the level of the iNos and an increase in eNos protein and the autophagy marker LC3. PRP has ameliorative effects on induced rat testicular toxicity as evaluated by morphological changes and confirmed by immunohistochemical reactions, genetic expression, and western blotting analyses including oxidative and anti- oxidative markers.

Abstract
BACKGROUND Platelet-rich plasma is a biological instrument rich in growth factors and cytokines. OBJECTIVES The aim of this study was to investigate the effect of platelet-rich plasma on spermatogenesis and hormone production in an experimental testicular torsion model. MATERIALS AND METHODS The rats were randomly divided into three groups, including six rats in each group as follows: the first group as the sham group; the second group as the ischemia/reperfusion + Saline group and the third group as the ischemia/reperfusion + platelet-rich plasma group. The left testicles of the ischemia/reperfusion + Saline and ischemia/reperfusion + platelet-rich plasma group were kept in four-hour torsion. Then, the left testicles of ischemia/reperfusion + Saline and ischemia/reperfusion + platelet-rich plasma groups were detorsioned, and intra-testicular 1 cc saline (ischemia/reperfusion + Saline) and 1 cc platelet-rich plasma (ischemia/reperfusion + platelet-rich plasma) were injected. At one month, blood samples were taken from all groups for hormonal evaluation and left orchiectomy was performed. RESULTS The mean follicle-stimulating hormone level of ischemia/reperfusion + Saline group was significantly higher than ischemia/reperfusion + platelet-rich plasma group (7.78 ± 0.23 vs 6.18 ± 0.28 nmol/l, respectively, P = .004). The mean LH level of ischemia/reperfusion + platelet-rich plasma group was significantly lower than ischemia/reperfusion + Saline group (3.63 ± 0.28 vs 5.68 ± 0.21 nmol/l, respectively, P = .004). The mean total testosterone level of ischemia/reperfusion + platelet-rich plasma group was significantly higher than ischemia/reperfusion + Saline group (8.05 ± 0.24 vs 5.78 ± 0.23 nmol/l, respectively, P = .004). The mean Johnsen scores of ischemia/reperfusion + platelet-rich plasma group were significantly higher than ischemia/reperfusion + Saline group (5.85 ± 0.58 vs 3.93 ± 0.65, respectively, P = .004). The mean Johnsen score of the sham group was significantly higher than ischemia/reperfusion + platelet-rich plasma and ischemia/reperfusion + Saline groups (P = .003 and P = .003, respectively). DISCUSSION AND CONCLUSION The platelet-rich plasma has beneficial effects on spermatogenesis and reproductive hormone production in testicular torsion. It is easily accessible and applicable. In the future, intra-testicular platelet-rich plasma injection may be used in testicular torsion after detorsion. However, further experimental and large-scale prospective clinical studies are needed to establish a definitive conclusion on this topic.

Abstract
Background: Striae distensae (SD) are common skin conditions.Objectives: This study was done to test the hypothesis that 'the use of microneedling (MN) before platelet-rich plasma (PRP) application will allow for deeper penetration and therefore, augment its efficacy in the treatment of SD.'Patients and methods: Forty patients with SD were divided into (i) Group I, the patients were treated with MN only, and (ii) Group II, the patients were treated with combined MN-PRP. The clinical improvement was evaluated by two dermatologists. Skin biopsies were obtained before and after therapy to examine immunohistological changes.Results: As compared to the use of MN alone, therapy with combined MN-PRP was associated with: (i) a marked to the excellent improvement of the skin lesions of SD, (ii) a more significant deposition of collagen and elastic fibers, (iii) increased proliferative activity in the epidermis, and (iv) a decreased caspase-3 protein expression values in the epidermis.Conclusions: This study proved that the combined MN-PRP is more effective than MN alone for the treatment of the lesions of SD. The underlying molecular mechanisms are open for future studies.

Abstract
This study was performed to evaluate the effect of chrysin on testicular torsion and detorsion damage in rats in terms of biochemistry, histopathology and immunohistochemistry. The study was performed on Wistar albino rats between 250 g and 300 g. A total of 40 rats were used. Five groups were created with eight rats in each group. Group 1 was the control group, and no torsion procedure was performed. In Group 2, 2 hr of torsion and 2 hr of detorsion were applied. In Group 3, 2 hr of torsion and 24 hr of detorsion were applied. In Group 4, 2 hr of torsion, 2 hr of detorsion and 50 mg/kg intraperitoneal chrysin were applied. In Group 5, 2 hr of torsion, 24 hr of detorsion and 50 mg/kg of chrysin were applied. In the torsion/detorsion groups, the study determined decreases in glutathione and testosterone levels, increases in tumour necrosis factor-α, interleukin-4, interleukin-6 and interleukin-10 levels, and increases in expression levels of caspase-3 and caspase-8. Chrysin application reduced malondialdehyde, tumour necrosis factor-α, caspase-3 and caspase-8 expression levels. We can say that chrysin can be used to reduce damage in cases of testicular ischaemia/reperfusion. For more reliable results, further clinical trials are recommended.

Sesamol Protects Testis from Ischemia-Reperfusion Injury through Scavenging Reactive Oxygen Species and Upregulating CREM τ Expression. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2020; 2020:9043806. [PMID: 32655774 PMCID: PMC7320277 DOI: 10.1155/2020/9043806] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 05/25/2020] [Accepted: 06/01/2020] [Indexed: 02/06/2023]
Abstract
Testicular torsion/detorsion-induced damage is considered as a typical ischemia-reperfusion injury attributed to excessive reactive oxygen species (ROS) production. ROS may regulate many genes whose expression affects cell-cycle regulation, cell proliferation, and apoptosis. The cAMP-responsive element modulator-τ (CREMτ) gene expression in the testis is essential for normal germ cell differentiation. The present study was aimed at investigating the effect of sesamol, a powerful antioxidant, on testicular ischemia-reperfusion injury and related mechanisms in an experimental testicular torsion-detorsion rat model. The type of our study was a randomized controlled trial. Sixty rats were randomly divided into the following 3 groups: (1) sham-operated control group (n = 20), (2) testicular ischemia-reperfusion group (n = 20), and (3) testicular ischemia-reperfusion+sesamol-treated group (n = 20). Testicular ischemia-reperfusion was induced by left testicular torsion (720° rotation in a counterclockwise direction) for 2 hours, followed by detorsion. Orchiectomy was performed at 4 hours or 3 months after detorsion. The testis was obtained for the analysis of the following parameters, including malondialdehyde level (a sensitive indicator of ROS), CREMτ expression, and spermatogenesis. In the testicular ischemia-reperfusion group, the malondialdehyde level was significantly increased with a concomitant significant decrease in CREMτ expression and spermatogenesis in ipsilateral testis. These results suggest that overproduction of ROS after testicular ischemia-reperfusion may downregulate CREMτ expression, which causes spermatogenic injury. Sesamol treatment resulted in a significant reduction in the malondialdehyde level and significant increase in CREMτ expression and spermatogenesis in ipsilateral testis. These data support the above suggestion. Our study shows that sesamol can attenuate testicular ischemia-reperfusion injury through scavenging ROS and upregulating CREMτ expression.

Abstract
AIMS This study was designed to evaluate the protective and therapeutic efficacy of platelet-rich plasma (PRP) against testicular degeneration and germ cell apoptosis after induced spermatic cord torsion/detorsion (TD) in rats. MATERIALS Forty rats were allocated into 5 groups: 1) control, 2) short torsion/detorsion (STD), 3) long torsion detorsion (LTD), 4) protective (PRP/P) and 5) treatment (PRP/T). Testicular ischemia was induced by twisting the right testis 1080° clockwise for 2.5 h. PRP (10 μl) was injected intra-testicular 5 min before (PRP/P) and 3 h after (PRP/T) detorsion. At the end of the experiment, rats were euthanized at 2, 30, 2, and 30 days for groups 2-5 respectively. Nitric oxide, malondialdehyde, catalase, total antioxidant capacity, reduced glutathione, glutathione-S-transferase, interleukin1 beta, tumor necrosis factor, caspase-3, and B-cell lymphoma 2 expressions were assessed in the testes. Moreover, histological examination was performed. KEY FINDINGS PRP treatment significantly mitigated the torsion-detorsion induced testicular degeneration. Particularly, by improving the state of oxidative stress (NO, P = 0.0001) and antioxidant markers (TAC, GSH, GST, P = 0.0001-0.01) and decreasing the expression of IL-1β, TNF-α and cas 3 and increase the BCL2 fold changes (P = 0.0001). The protective use of PRP is superior to the therapeutic use of PRP in the restoration of the testicular histoarchitecture following TD. SIGNIFICANCE This study illustrates the cyto-protective role of PRP against TD induced testicular cell injury that highlight possible application of PRP as a complementary therapy in different testicular degenerative diseases which might attribute to its ability to ameliorate the oxidative stress and inhibit induced apoptosis.

Abstract
Platelet-rich plasma (PRP) is a therapeutic option in different fields based on its growth factors. We investigated influence of PRP on islet survival, function, transplantation outcomes, and pancreatic genes expression in diabetic rats. In vitro: pancreatic isolated islets were incubated with/without PRP then viability, insulin secretion, and content were assessed. In vivo: Series 1 were designed to determine whether islet treatment with PRP improves transplantation outcome in diabetic rats by evaluating plasma glucose and insulin concentrations and oxidative parameters. Series 2, effects of PRP subcutaneous injection were evaluated on pancreatic genes expression and glucose tolerance test in diabetic rats. PRP enhanced viability and secretary function of islet. Reduced glucose and malondialdehyde levels as well as increased insulin levels, superoxide dismutase activity, and expressions of pdx1 and insulin were observed in diabetic rats. PRP treatment has positive effects on islet viability, function, transplantation outcome, and pancreatic genes expression in diabetic rats.

Abstract
Our study aimed to investigate the effects of platelet-rich plasma (PRP) on impaired glucose homeostasis, disrupted islet insulin secretion, and pancreatic oxidative status in streptozotocin (STZ)-diabetic rats. A total of 64 Sprague-Dawley male were randomized to four groups including controls, diabetes, control-PRP, and diabetes-PRP. The rats received the PRP (0.5 ml/kg, SC injection) twice weekly for 4 weeks. Plasma glucose and insulin levels, pancreatic oxidative stress markers and islet insulin secretion and content were measured. Compared with the control group, in the diabetic group, increased plasma glucose and malondialdehyde (MDA) levels and decreased plasma insulin level, islet insulin secretion, pancreatic superoxide dismutase (SOD), and catalase activities were observed. PRP treatment significantly reduced plasma glucose and MDA levels and enhanced plasma insulin, antioxidant enzyme activity, islet insulin secretion, and content in the diabetic rats. These findings showed that PRP can improve pancreatic islet insulin secretion, pancreatic oxidative stress and regulate plasma insulin and glucose levels in diabetic rats.

Abstract
Chronic kidney diseases occur as result of exposure to wide range of deleterious agents as environmental pollutants, toxins and drug. Currently, there is no effective protective therapy against renal damage, fibrosis and its sequel of end stage renal disease. Platelet-rich plasma (PRP) has a progressively gained consideration in wound healing, repair/regeneration of damaged tissues and conservation of organ function. However, its impact on thioacetamide (TAA) induced chronic renal damage has not been elucidated yet. So, the present study was carried out to evaluate the possible protective and regenerative effect of PRP against TAA induced renal damage and their potential underlying mechanism. PRP treatment improved redox state, renal function disturbed histologicl features; decreased monocyte chemo-attractant protein-1 (MCP-1) level; increased Peroxisome proliferator-activated receptor gamma co-activator-1α (PGC-1α) marker of mitochondrial biogenesis and metabolism; cyclic adenosine monophosphate (cAMP); hepatocyte growth factor (HGF) and autophagy protein beclin-1 level. In addition, PRP treatment decreased apoptosis and fibrosis as evidenced by decreased active caspase3 and α-SMA expression and immunoreactivity, respectively. In conclusion, PRP could potentially protect against TTA-induced chronic kidney damage by alleviating oxidative stress, improving, mitochondrial biogenesis, autophagy, disruption of the inflammatory, apoptotic and fibrotic response induced by TTA.

Abstract
Testicular torsion causes ischemia-reperfusion injury and an increased risk of infertility. Nesfatin-1 is a novel peptide with antioxidant, anti-inflammatory and anti-apoptotic properties. In the present study, we aimed to investigate the putative beneficial effects of nesfatin-1 on oxidative injury and impaired testicular function induced by testis torsion. Under anesthesia, male Sprague-Dawley rats (180-230 g; n = 24) had sham-operation or they underwent testicular torsion by rotating the left testis 720° and fixing it for 2 h, followed by a 2-h detorsion. Rats in each group were treated intraperitoneally with either nesfatin-1 (0.3 μg/kg) or saline prior to the torsion or sham-torsion. At the end of the 4-h experimental period, tissue samples were removed for evaluation of spermatozoa, molecular and histochemical analyses. In saline-treated torsion/detorsion group, a high percentage of abnormal spermatozoa with head defects was observed, which was abolished in nesfatin-1-treated torsion/detorsion group. The levels of 8-OHdG, tumor necrosis factor (TNF)-alpha, interleukin (IL)-6, caspase-3 were increased in the saline-treated torsion/detorsion group as compared to sham-operated group, while nesfatin-1 pre-treatment significantly decreased the expressions of the pro-inflammatory cytokines, depressed apoptosis, and also reduced the tubular degeneration. In addition, nesfatin-1 in torsion/detorsion group elevated expressions of transforming growth factor (TGF)-beta and reduced expressions of protein kinase B (AKT) and cAMP response element binding protein (CREB) in the testis tissue. The present findings show that nesfatin-1, by regulating AKT and CREB signaling pathways and pro-inflammatory/anti-inflammatory cytokine balance, preserves the spermatogenic cells and ameliorates torsion-detorsion-induced tubular degeneration.

Abstract
Torsion/detorsion (T/D) induces testicular damages in both germinal epithelial and interstitial tissues. Ginkgo biloba extract (GbE) exerts antioxidant and free radical scavenger. We investigated the effect of GbE on testicular tissues, Leydig and sperm cells in rats injured with T/D. Twenty-eight Wistar albino rats were randomly assigned into four groups (Control, GbE, Treatment: T/D+GbE, T/D). T/D performed to the rats in torsion, treatment received GbE (50 mg/kg) 1 hr before T/D, GbE group received only GbE (50 mg/kg) and control was defined as sham group. After T/D, the testes along with epididymis were removed and processed. LH-R expression, apoptosis, sperm morphology and histopathological damage scores were determined for each group. Testicular T/D caused significant increases in apoptosis and sperm morphology anomaly, and a significant decrease in Johnsen's testicular biopsy scores, LH-R expression of Leydig cell and normal sperm cell count. GbE ameliorated testicular histopathology and caused significant increases in LH-R expression, normal sperm cell count in the treated and particularly GbE group. Consequently, GbE may prevent testicular injury and enhance Leydig and sperm cell activity following both T/D and normal situation owing to its antioxidant, anti-apoptotic, free radical scavenger and anti-inflammatory effects.
