RESUMO

Protein C deficiency is a rare blood disorder that increases the risk of thromboembolism, resulting in deep vein thrombosis, pulmonary embolisms and strokes. Segmental testicular infarction is also a rare condition with unclear aetiology. This case presents a man in his 50s with protein C deficiency who developed a segmental testicular infarction. The patient was managed conservatively, without surgical intervention. He was monitored with serial ultrasound, which demonstrated progression from normal testis to segmental infarction and eventually resolution. The case highlights that protein C deficiency can cause testicular infarction, and a multidisciplinary approach can help avoid unnecessary surgery with excellent outcomes. Segmental infarction should be considered in patients with pre-existing thrombophilias after excluding malignancy and infection. Conservative management with repeat ultrasonography and follow-up can be appropriate in such cases.

RESUMO

PURPOSE: Hypercholesterolemia due to a high-cholesterol diet is linked to numerous diseases and may lead to male infertility. However, the underlying mechanism remains unknown. The maintenance of male fertility requires intact testicular structures (including seminiferous tubules and mesenchyme) and functioning cells (Leydig cells, Sertoli cells and germ cells, etc.), production of appropriate concentrations of sex hormones, and cooperation among testicular cells. Thus, we considered whether male fertility declined as the structure and function of testicular cells were altered in rats on a high-cholesterol diet. METHODS: Male Sprague Dawley rats were fed either a standard or a high-cholesterol diet for 16 weeks. Serum sex hormones, lipid components, semen quality, and fertility rate were assayed in the rats. The 3ß-hydroxysteroid dehydrogenase (3ß-HSD), Wilms tumor 1 (WT-1), and deleted in azoospermia-like (DAZL) were regarded as specific markers of Leydig, Sertoli, and germ cells in rats. In addition, the ultrastructure of the testis and expression levels of particular marker molecules of testicular cells were further investigated. RESULTS: Compared to rats fed on a regular diet, the serum testosterone levels and sperm progressive motility decreased in rats fed high cholesterol. Moreover, we observed a deformed nucleus, dilated smooth endoplasmic reticulum, and swollen mitochondria of Leydig cells and a schizolytic nucleus of Sertoli cells in rats on a high-cholesterol diet. The 3ß-HSD, WT-1, and DAZL protein expression levels were significantly reduced in rats on a high-cholesterol diet. CONCLUSIONS: Our results showed that a high-cholesterol diet adversely affected testosterone production and sperm progressive motility, possibly due to Leydig, Sertoli, and germ cell abnormalities.

RESUMO

RATIONALE: Rare side effects of acute epididymitis include testicular infarction and ischemia. Distinguishing them from testicular torsion is challenging, both clinically and radiologically. However, only a few such cases have been reported to date. PATIENT CONCERNS: A 12-year-old child presented with persistent right testicular pain for 3 days. It developed after trauma and was accompanied by gradual swelling and enlargement of the right scrotum, with nausea and vomiting. Scrotal color Doppler ultrasonography demonstrated right epididymitis, right scrotal wall swelling, and right testicular torsion. Routine blood tests revealed leukocyte and neutrophil counts were both above normal. DIAGNOSIS: Scrotal exploration revealed edema and adhesions in all layers of the scrotal wall. The right testicle was pale. The patient was diagnosed with testicular ischemia secondary to acute epididymitis. INTERVENTIONS: The patient underwent simultaneous lower spermatic cord sheath dissection and decompression, testicular sheath reversal, and right testicular fixation. OUTCOMES: Blood flow to the testicles gradually recovered after decompression, as did the color. Postoperatively, the patient's scrotal swelling and pain improved significantly. LESSONS: Despite the rarity of this condition, it is a potentially serious consequence of epididymitis and should be considered when patients experience sudden scrotal pain.

RESUMO

INTRODUCTION: Varicocele is an abnormal dilatation of the internal spermatic veins of the spermatic cord. It has an estimated prevalence of 15% in young male adults. Even though most of them are asymptomatic, scrotal pain and testicular hypotrophy are frequent in children and adolescents. There is controversy regarding the indications and optimal approach for treatment purposes. We present the results of our 15-year series in the laparoscopic repair of pediatric varicocele. MATERIALS AND METHODS: 238 patients diagnosed with varicocele and undergoing laparoscopic repair from 2006 to 2020 were reviewed. Variables collected included age, symptoms, grade, testicular atrophy, hospital stay, perioperative complications, recurrences, and formation of reactive hydrocele. Mean follow-up was 5.6 years (6 months-9 years). RESULTS: Mean age was 14.1 years. 188 patients had grade III varicocele. In 14 cases, varicocele was bilateral. Testicular atrophy at diagnosis was found in 42% of patients, 74% of whom were over 15 years old. 51 patients had testicular pain. All patients underwent laparoscopic treatment. Mean operating time was 36 min. Median hospital stay was 31 h. Recurrence rate was 2.1%. 43 patients (18%) developed hydrocele, but only 27 (11.2%) required hydrocelectomy according to Lord's plication at least 1 year following laparoscopy. Of the remaining 16 cases, 2 spontaneously resolved and 14 remained stable in the mean 7-year follow-up. In 7.1%, paresthesias were noted in the anterior-internal aspect of the left thigh. CONCLUSION: Based on our series, we believe laparoscopy should be regarded as the gold standard technique in the pediatric population. Laparoscopic varicocelectomy is technically easy and fast, causes no pain, and has a recurrence rate of 1%. The procedures involving lymphatic vessel preservation could reduce reactive hydrocele rates as a long-term complication to a minimum.


INTRODUCCION: El varicocele es una dilatación anormal de las venas espermáticas internas del cordón espermático. Su prevalencia se estima en 15% de varones adultos jóvenes. Aunque la mayoría son asintomáticos, en niños y adolescentes el dolor escrotal y la hipotrofia testicular son frecuentes. Existe controversia sobre las indicaciones y el abordaje óptimo para su tratamiento. Presentamos los resultados de nuestra serie de 15 años en la reparación laparoscópica del varicocele pediátrico. MATERIAL Y METODOS: Revisamos 238 pacientes diagnosticados de varicocele y sometidos a corrección laparoscópica desde 2006 hasta 2020. Las variables registradas fueron: edad, síntomas, grado, atrofia testicular, duración de la estancia, complicaciones perioperatorias, recidivas y formación de hidrocele reactivo. El seguimiento medio fue 5,6 años (6 meses-9 años). RESULTADOS: La edad promedio fue 14,1 años. 188 pacientes presentaban varicocele grado III. En 14 casos el varicocele era bilateral. Se observó atrofia testicular en 42% al diagnóstico, de los que el 74% eran mayores de 15 años. Cincuenta y un pacientes refirieron dolor testicular. Todos los pacientes se sometieron al tratamiento laparoscópico. El tiempo operatorio promedio fue 36 min. La mediana de estancia fue 31 horas. La tasa de recidiva fue 2,1%. Cuarenta y tres pacientes desarrollaron hidrocele (18%); pero solo 27 precisaron hidrocelectomía según plicatura de Lord al menos un año poslaparoscopia (11,2%). De los 16 restantes, dos se resolvieron espontáneamente y 14 se mantuvieron estables en el seguimiento medio de siete años. En 7,1% se notificaron parestesias en la cara anterointerna del muslo izquierdo. CONCLUSION: Basándonos en nuestra serie, creemos que la laparoscopia debe considerarse el gold standard en edad pediátrica. La varicocelectomía laparoscópica es técnicamente fácil y rápida, indolora y con una tasa de recurrencia del 1%. Los procedimientos de preservación de los linfáticos podrían reducir al mínimo las tasas de hidrocele reactivo como complicación a largo plazo.

RESUMO

Epididymo-orchitis (EO) is a common urologic condition that rarely requires surgical intervention. Global testicular infarction is an exceedingly uncommon complication of EO and is thought to occur when severe epididymal edema compresses testicular vessels. We present a rare case of global testicular infarction secondary to EO in a 17-year-old boy. Predicting which cases of EO will progress to testicular ischemia is challenging, as no clear risk factors have been identified. Early recognition of testicular compromise requires a high degree of clinical suspicion and may provide the opportunity for testis-sparing intervention.

RESUMO

INTRODUCTION: In this report, we discuss the evaluation of a patient with chronic scrotal pain found to have a supernumerary testis (SNT), as well as a novel microsurgical approach to safely removing this testis. TECHNICAL CONSIDERATIONS: To avoid any iatrogenic injury to the adjacent testis, we used an operating microscope to visualize the cord structures of both testes and carefully remove the smaller, atrophic, supernumerary testis. The surgery was successfully completed without any intraoperative or postoperative complications. Total operative time was 2 hours. While the patient had not yet attempted to conceive at the time of follow-up, given our careful dissection, we expect him to have normal testicular function and fertility in the future. CONCLUSION: This case demonstrates a novel microsurgical approach to excising a supernumerary testis that avoids injury to the blood supply, epididymis, and vas deferens associated with the normal testis.

RESUMO

Varieties of studies have been used to investigate the health benefits of Spirulina (Arthrospira platensis); however, more research is needed to examine if its nano form may be utilized to treat or prevent several chronic diseases. So, we designed this study to explore the effect and the cellular intracellular mechanisms by which Arthrospira platensis Nanoparticles (NSP) alleviates the testicular injury induced by diabetes in male Wistar rats. Eighty Wistar male rats (n = 80) were randomly allocated into eight groups. Group 1 is untreated rats (control), Group 2 including STZ-induced diabetic rats with 65 mg/kg body weight STZ (STZ-diabetic), Group 3-5: including diabetic rats treated with NSP1, NSP2, and NSP3 at 0.25, 0.5, and 1 mg/kg body weight, respectively, once daily orally by the aid of gastric gavage for 12 consecutive weeks and groups 6-8 include normal rats received NSP (0.25, 0.5, and 1 mg/kg body weight once daily orally. The identical volume of normal saline was injected into both control and diabetic rats. After 12 weeks of diabetes induction, the rats were killed. According to our findings, NSP administration to diabetic rats enhances the total body weight and the weight of testes and accessory glands; in addition, NSP significantly reduced nitric oxide and malondialdehyde in testicular tissue improved sperm parameters. Intriguingly, it raises testicular GSH and SOD activity by a significant amount (p < 0.05). As well, Oral administration of NSP to diabetic rats resulted in a decrease in the blood glucose levels, HA1C, induced in the diabetic group, which overcame the diabetic complications NSP caused down-regulation of apoptotic genes with upregulation of BCL-2 mRNA expression (p < 0.05) and prominent up-regulation of steroidogenesis genes expression level in testes in comparison to the diabetic rats which resulted in improving the decreased levels of testosterone hormone, FSH, and LH induced by diabetes. In the same way, our histopathological findings support our biochemical and molecular findings; in conclusion, NSP exerted a protective effect against reproductive dysfunction induced by diabetes not only through its high antioxidant and hypoglycemic action but also through its down-regulation of Apoptotic genes and up-regulation of steroidogenesis regulatory genes expression level in diabetic testes.

RESUMO

The testicles and sperm are extremely susceptible to inflammation and oxidative stress. Although Zhibai Dihuang Pill (ZDP) has been reported to treat various infertilities including male infertility induced by Ureaplasma urealyticum (UU) infection, its mechanism is still poorly understood. This study is aimed at clarifying the underlying mechanism of ZDP to protect against UU-infected male infertility. We found that UU-infected infertile rats exhibited weight loss, reduced food intake, and decreased sperm count and vitality. The administration of ZDP improved the general state and sperm motility of rats. In addition, UU infection led to spermatogenesis disorders, impaired secretory function and blood-testis barrier (BTB) of Sertoli cells, and elevated inflammation and oxidative stress. As expected, ZDP suppressed inflammation and oxidative stress to alleviate spermatogenesis disorders. Our research showed that ZDP could improve spermatogenesis disorders and testicular function primarily through the mitogen-activated protein kinase (MAPK) signaling pathway. ZDP exerts its anti-inflammatory and antioxidant effects via the MAPK signaling pathway, thus playing an important role in ameliorating spermatogenesis failure and testicular dysfunction.

RESUMO

BACKGROUND: Testicular torsion is still an urgent surgical condition and without any treatment it can cause infertility. The main pathophysiology of testicular torsion ischaemic injury however; the main sequalae of detorsion is reperfusion injury. Furthermore; treatments to prevent ischemic reperfusion injury due to decreased blood flow are important to preserve testicular function. AIMS: Human chorionic gonadotropin ß (ß-hCG) is an anabolic hormone that supports steroidogenesis and spermatogenesis. Vitamin C (Vit-C) is one of the water-soluble vitamins and is also a potent antioxidant in ischemic damage. Moreover, it has protective effects by increasing blood and lymph flow in the testicles. The aim of this study is to investigate the effects of ß-hCG, Vit-C and their combination on ischemic reperfusion injury occurring after surgical treatment of testicular torsion. STUDY DESIGN: Animal research studies. METHODS: The study was performed on 25 male Wistar albino rats. The animals were divided equally into 5 groups. In the first group "Control Group," left orchiectomy was performed. In the second group "Sham Group," a 720° clockwise torsion was created and after 4 h of left testicular torsion it was detorsioned for 4 h and then left orchiectomy was performed. In the third group same procedure was applied with 30 mg vitamin C was administered via intraperitoneal route once a week for 3 weeks. In the fourth group after same surgical procedures 75 IU ß-hCG was administered via intraperitoneal route once a week for 3 weeks. In the fifth group after 4 h left testicle torsion it was detorsioned for 4 h then, 75 IU ß-hCG and vitamin C together were administered via intraperitoneal route once a week for 3 weeks. Left orchiectomy was performed after 3 weeks in the third, fourth and fifth groups. Specimens were evaluated histologically. RESULTS: Testicular tissue histopathological evaluations were performed. A high histopathological stage indicates more testicular damage, and a low one was indicated less testicular damage. The average histopathological grade of vitamin C + ß-hCG group was significantly higher than the average histopathological grade of the control, the sham group and vitamin C group. The average histopathological grade of the vitamin C group was significantly lower than the average histopathological grade of sham and ß-hCG groups. The ratio of the testicular atrophy of the Vitamin C + ß-hCG group (100%) was higher than sham (40%) and ß-hCG (40%) groups with a significant difference. A significant statistical difference was found among all groups histopathological grades of testicular tissue. CONCLUSION: In animals taking vitamin C, an improvement of histopathological findings and a significant decrease in histological stages has been provided. However, it was observed that the histological findings of ß-hCG and ß-hCG + vitamin C groups worsened. It was found that ß-hCG increased oxidative damage in the testicles and this damage can be so severe that exceeding the capacity of potent antioxidants such as Vitamin C. We believe that ß-hCG can be harmful to testicles exposed to oxidative damage.

RESUMO

BACKGROUND: Testicular injury is one of the most serious problems associated with diabetes mellitus. The present study aimed to compare the effects of two different doses of nobiletin and analyze its mechanisms of action against diabetes-induced testicular impairment in rats. METHODS AND RESULTS: Streptozotocin injection was used to induce diabetes. Diabetic rats received nobiletin orally at 10 or 25 mg/kg daily for 30 days. Diabetic rats displayed significant elevations in glucose, glycosylated hemoglobin (HbA1c), Homeostatic Model of Insulin Resistance (HOMA-IR), and pro-inflammatory cytokines, while the serum levels of insulin, testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were significantly reduced. Histological changes to positivity for caspase-3 and decreased androgen receptors (AR) immunoexpression were observed in diabetic rats. Both doses of nobiletin improved hyperglycemia, reduced pro-inflammatory cytokines, and augmented insulin, testosterone, LH, and FSH levels. LH and FSH receptors and cytochrome P450 17 α-hydroxylase (CYP17A1) were markedly downregulated in terms of both gene and protein expression in testicular tissues of the diabetic group, effects that were markedly ameliorated with both doses of nobiletin. In addition, both doses significantly reduced lipid peroxidation and caspase-3 immunoexpression and improved the activity of the antioxidant enzymes and AR in testicular tissues of the diabetic group. CONCLUSION: Both nobiletin doses showed protective effects against diabetes-induced testicular injury by reducing oxidative stress, hyperglycemia, inflammation, and caspase-3 and upregulating the hypophysis-gonadal axis and AR. The high dose of nobiletin was more effective than the lower one.

RESUMO

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.

RESUMO

BACKGROUND: Testicular torsion, which causes ischemia-reperfusion (IR) injury, is a serious urological emergency that can lead to testicular dysfunction, including infertility, primarily among newborn and pubertal males; thus, effective drugs should be administered during or after ischemia. OBJECTIVES: Using a rat model of testicular IR injury, the present study investigated the protective effects of relaxin (RLN) against oxidative stress, testicular dysfunction, inflammation, histological damage, arrested spermatogenesis, and germ cell apoptosis as well as explored the usefulness of RLN as a potential protective drug for IR injury combined with surgical treatment. MATERIALS AND METHODS: Male Sprague-Dawley rats were subjected to left testicular ischemia for 2 h, followed by 24 h of reperfusion. They were subsequently divided into three groups: sham, IR, and IR + RLN groups. Porcine RLN (500 ng/h) or saline was infused using an implanted osmotic mini-pump 90 min after inducing ischemia. The RLN dose used herein was that which resulted in serum RLN levels comparable to those in mid-pregnant rats based on previous studies. RESULTS: Testicular IR increased germ cell apoptosis and histological damage as well as promoted disorganized and arrested spermatogenesis, accompanied by a significant increase in oxidative stress and inflammation. However, RLN administration ameliorated the adverse consequences associated with IR injury by attenuating oxidative stress and mitigating apoptosis and inflammation. DISCUSSION AND CONCLUSION: The study findings clearly demonstrated that RLN exerts a protective effect against IR-induced testicular injury by attenuating oxidative stress, apoptosis, and inflammation, suggesting that RLN together with surgical treatment is a potentially efficacious approach toward ameliorating testicular dysfunction following testicular torsion.

RESUMO

<b>Background and Objective:</b> Obesity exerts negative influences on male reproductive capacity via changing the molecular and physical structure of male germ cells. This study was conducted to evaluate the mitigating effects of raw juice of pineapple on obesity-associated testicular impairment in male Wistar rats. <b>Materials and Methods:</b> Rats included the control group (G<sub>I</sub>, n = 6) who received a Normal Diet (ND) and the obese group (G<sub>II</sub>, n = 18) who received a High-Fat Diet (HFD). Obese rats (G<sub>II</sub>) were subdivided into 3 groups (6 rats each): G<sub>II</sub> represents the untreated obesity group that continued to receive HFD with plain Drinking Water (DW), G<sub>III</sub> received ND along with raw juice (15% v/v) in DW and G<sub>IV</sub> continued to receive HFD with raw juice (15% v/v) in DW. Rats were sacrificed at the end of the trial and testis was processed for histopathology and immunohistochemistry. <b>Results:</b> Testis from obese rats revealed a significant increment in spermatogenic cell degeneration, pro-inflammatory Nuclear factor of kappa B (NF-κB) and pro-apoptotic Caspase-3 immunoreactivities. Yet, Proliferating Cell Nuclear Antigen (PCNA) displayed poor immunoreactivity in obese rats' testis relative to controls. Administration of raw juice of pineapple to obese rats significantly reduced degeneration of spermatogenic cells, NF-κB and Caspase-3 immunoreactivities. Additionally, treatment with the juice significantly increased immunoreactivity to PCNA in obese rats. These ameliorating effects were more obvious in rats who received juice along with ND (G<sub>III</sub>) than in those who received it along with HFD (G<sub>IV</sub>). <b>Conclusion:</b> Treatment of obese rats with pineapple juice restored testicular homeostasis, indicating its potential validity to overcome obesity-induced male fertility disorders.

RESUMO

Twisting of the spermatic cord is a common dangerous health problem that may be accompanied with testicular necrosis and infertility. Cilostazol (CLZ) is a selective phosphodiesterase (PDE) 3A inhibitor used for treatment of intermittent claudication. It has a great role in myocardial, spinal cord and hepatic ischaemia/reperfusion. However, till now, there are no researches evaluating its role in testicular ischaemia/reperfusion (TIR). The current work studies its capability to improve TIR induced injury with more concentration on the mechanisms involved in such effect. Four groups of animals were included: sham, TIR induced group, TIR plus CLZ low dose (10 mg/kg), TIR plus CLZ high dose (30 mg/kg). Our results proved that TIR had significant decrease of the serum ELISA of testosterone, marked disturbances in oxidative stress evaluated parameters as malondialdehyde (MDA), reduced glutathione (GSH), total antioxidant capacity (TAC), ELISA measurement of tumor necrosis factor alpha (TNFα) and interleukin 1 beta (IL1ß) inflammatory mediators, apoptotic marker (caspase3) using western blotting, immunohistochemistry of hypoxia inducible factor-1α (HIF-1α) and vascular endothelial growth factor (VEGF). TIR reduced the protective agents as cyclic adenosine monophosphate (cAMP) and sirtuin-1 (SIRT1) by ELISA method with marked germinal cell apoptosis. The biochemical results were confirmed by the histopathological findings that showed marked decrease in both Johnsen's score and Cosentino's score. However, treatment with CLZ significantly reversed the profound TIR damaging effects, on the basis of its anti-inflammatory, anti-oxidant, and anti-apoptotic activities with recuperation of the testicular vascularity. Modulation of HIF/VEGF and cAMP/SIRT1 pathways showed a great role in mediating such effect.

RESUMO

BACKGROUND: Testicular torsion/detorsion triggers tissue ischemia/reperfusion, leading to reactive oxygen species overgeneration and apoptosis. The saliva of leeches is full of anti-inflammatory, anticoagulants, antioxidants, and antimicrobial agents. Therefore, this study aimed to assess the protective mechanism of leech therapy on testicular ischemia/reperfusion damage. METHODS: 18 adult male rats were randomly divided into three groups: 1-Sham-operated group (SO). 2-Torsion/detorsion (T.D) group: two hours of testicular torsion with two hours of testicular detorsion was performed. 3-Torsion/detorsion + Leech therapy (TDL) group. Sperm parameters (motility, vitality, morphology, and concentration), oxidative stress biomarkers (MDA, CAT, GPx, and TAC), histopathological factors (Mean seminiferous tubular diameter, Germinal epithelial cell thickness, Testicular capsule thickness, Johnson's score, and Cosentino's score), and immunohistochemical markers for apoptosis detection (Bax, Bcl-2, and Caspase-3) were measured. RESULTS: There was a significant difference for all sperm parameters in the T. D group compared to the sham group. Leech therapy significantly increased progressive motility and normal morphology and reduced non-progressive motility. In the TDL group, MDA concentration significantly reduced, and levels of GPx, TAC, and CAT remarkably increased. All evaluated histopathological parameters in the TDL group significantly increased compared to the T. D group except for the testicular capsule thickness. T. D notably increased the expression of Bax and Caspase-3, while the treatment group slowed the rate of apoptosis compared to the control group. Bcl-2 expression in the T. D group was significantly lower than that in the sham group. Leech therapy increased the Bcl-2 expression. CONCLUSION: Leech therapy attenuates damages to testicular tissue following torsion/detorsion due to its antioxidant, anti-inflammatory, and anti-apoptotic effects. Hence, it can be considered as an effective remedy for testicular ischemia/reperfusion.

RESUMO

ETHNOPHARMACOLOGICAL RELEVANCE: Raffia palm (Raphia hookeri G. Mann & H. Wendl) wine (RPW) is a natural beverage obtained from the R. hookeri consumed for refreshment and medicinal purposes. For medicinal purposes, it is used singly or as macerating agent for other medicinal plants for the treatment of several diseases. AIM: This study investigates the effect of Raffia palm wine on dysregulated lipid metabolic pathways in testicular tissues of type 2 diabetic (T2D) rats. METHODS: Raffia palm wine (150 and 300 mg/kg bodyweight) was administered to two T2D groups respectively, another T2D group was not administered treatment and served as negative control, while metformin served as the standard drug. After 6 weeks of treatment, the rats were sacrificed, and the testes collected. After weighing, the organs were homogenized in 20% methanol/ethanol and centrifuged at 20,000 g to extract the lipid metabolites. RESULTS: GC-MS analysis of the supernatants revealed an alteration of the metabolites on induction of T2D, with concomitant generation of 10 metabolites. Raffia palm wine inhibited the T2D-generated metabolites while replenishing cholesterol and squalene levels, with concomitant generation of 7 and 8 metabolites for low and high dose treatment respectively. Pathway enrichment analysis of the metabolites revealed a decreased level of steroid biosynthesis and increased level of fatty acid biosynthesis. Raffia palm wine inactivated glycerolipid, fatty acid, and arachidonic acid metabolisms, fatty acid biosynthesis and fatty acid elongation in mitochondria pathways, and activated pathways for plasmalogen synthesis, mitochondrial beta-oxidation of long chain saturated fatty acids. CONCLUSION: The replenishment and generation of these metabolites and additional ones as well as activation of pathways involved in energy generation, phospholipids, antioxidant activity, steroidogenesis and spermatogenesis suggest a therapeutic effect of Raffia palm wine against hyperglycemic-induced testicular dysfunction.

RESUMO

SUMMARY: A large body of evidence supports the protective role of the flavonol antioxidant compound quercetin in mammals. We tested the hypothesis that quercetin can protect against the hypothalamus-pituitary-gonadal (HPG) axis defect like a reduction in gonadotropins and testicular hormones and abnormal semen analysis induced by chronic unpredictable stress (CUS), possibly via the downregulation of oxidative stress (ROS) and p53-Bax-caspase-3 pathways. Rats were either exposed to a variety of unpredictable stressors daily before being sacrificed after 3 weeks (model group) or were treated with quercetin (50 mg/kg body weight/day) at the same time the CUS were induced (treated group). Harvested testicular tissues were stained with basic histological staining, and testis homogenates were assayed for the tumor suppressor p53, apoptosis regulator Bax, B-cell lymphoma 2 (Bcl-2), caspase-3, malondialdehyde (MDA), glutathione peroxidase (GPx), and superoxide dismutase (SOD). In addition, harvested epididymis tissues were used to assess semen analysis, and blood samples were assayed for the testicular hormone testosterone, the adrenal cortex hormone corticosterone, and the anterior pituitary gonadotropins, follicular stimulating hormone (FSH) and luteinizing hormone (LH). CUS induced profound testicular damage and significantly (p<0.05) induced p53, Bax, caspase-3, MDA, and corticosterone, which were significantly (p<0.05) inhibited by quercetin except corticosterone. Whereas, quercetin significantly (p<0.05) increased FSH, LH, testosterone, Bcl-2, GPx, and SOD levels that were inhibited by CUS. In addition, CUS induced oligozoospermia, asthenozoospermia, and teratozoospermia, which were significantly (p<0.05) protected by quercetin. Thus, Quercetin protects against CUS-induced HPG defects in rats, which is associated with the inhibition of ROS-p53-Bax-caspase-3 axis.


RESUMEN: El papel protector del compuesto antioxidante flavonol quercetina en los mamíferos ha sido ampliamente reportado. Probamos la hipótesis que la quercetina puede proteger contra el defecto del eje hipotálamo-hipofisiario- gonadal (HHG) como una reducción de gonadotropinas y hormonas testiculares y análisis de semen anormal inducido por estrés crónico impredecible (ECI), posiblemente a través de la regulación reducida del estrés oxidativo (REO) y las vías p53- Bax-caspasa-3. Las ratas fueron expuestas a una variedad de fac- tores estresantes impredecibles diariamente antes de ser sacrificadas después de 3 semanas (grupo modelo) o fueron tratadas con quercetina (50 mg / kg de peso corporal / día) al mismo tiempo que se indujo la ECI (grupo tratado). Los tejidos testiculares fueron teñidos con tinción histológica básica y los homogeneizados de testículo se analizaron para determinar el supresor de tumores p53, el regulador de apoptosis Bax, el linfoma de células B 2 (Bcl-2), la caspasa-3, el malondialdehído (MDA), la glutatión peroxidasa (GPx) y superóxido dismutasa (SOD). Además, se utilizaron tejidos del epidídimo recolectados para evaluar el análisis de semen y se analizaron muestras de sangre para determinar la hormona testicular testosterona, la hormona corticosterona de la corteza suprarrenal y las gonadotropinas de la hipófisis anterior, la hormona estimulante folicular (FSH) y la hormona luteinizante (LH). El ECI indujo daño testicular importante e indujo significativamente niveles de (p <0,05) p53, Bax, caspasa-3, MDA y corticosterona, que fueron inhibidos (p <0,05) por la quercetina. La quercetina aumentó significativamente (p <0,05) los niveles de FSH, LH, testosterona, Bcl-2, GPx y SOD que fueron inhibidos por ECI. Además, ECI indujo oligozoospermia, astenozoospermia y teratozoospermia, protegidos de manera significativa (p <0,05) por la quercetina. Por lo tanto, la quercetina protege contra los defectos de HHG inducidos por ECI en ratas, lo que está asociado con la inhibición del eje ROS-p53-Bax-caspasa-3.
