Abstract
Objective: We evaluated the preventive effects of aqueous and ethanolic extracts of Dracaena arborea on sperm characteristics and oxidative stress markers in adult male rats with varicocele. Methods: Thirty-six male Wistar rats were randomly distributed into 6 groups (6 animals/group) and treated for 30 days as follows: (1), normal rats receiving distilled water (10 ml/kg); (2), sham operated rats receiving distilled water (10 ml/kg); (3), varicocele rats receiving distilled water (10 ml/kg); (4), varicocele rats receiving vitamin E (150 mg/kg); (5-6), varicocele rats administered respectively with aqueous (500 mg/kg) and ethanolic (100 mg/kg) extracts of D. arborea. All rats (except normal and sham-operated groups) underwent varicocele induction. At the end of the treatment period, sexual organ weights, oxidative stress, sperm characteristics and some biochemical parameters were measured. Results: A significant decrease (p<0.01) in sperm density (137.81±7.76 vs. 175.83±4.86), sperm motility (55.43±4.49 vs. 77.96± 3.15) and sperm normality (44.75±2.80 vs. 79.25±1.84) was noticed in varicocele-untreated rats compared with controls. Varicocele also induced oxidative stress by decreasing superoxide dismutase (SOD) and catalase activities, and increasing malondialdehyde (MDA) levels. These alterations were prevented by D. arborea. For instance, the aqueous extract of D. arborea (500 mg/kg) significantly increased (p<0.05-0.001) testes and epididymis weights, sperm viability and sperm motility, while the ethanolic extract (100 mg/kg) increased sperm normality compared with varicocele-untreated rats. D. arborea extracts also decreased MDA levels, but elevated catalase activity. Conclusions: Dracaena arborea prevents the deleterious effects of varicocele and could be considered as an alternative treatment of this physiopathology.

Abstract
BACKGROUND Varicocoele-associated stressors, such as hypoxia and heat, can damage cell function and viability, and some exosomal biomarkers released from impaired cells may reflect the cell status in testis. OBJECTIVES To find if seminal exosomal microRNAs can reflect the Sertoli cell function in varicocoele. MATERIALS AND METHODS Experimental left varicocoele rat model was established (n = 24), and patients with different grades of varicocoele (n = 104) were enrolled. Primary rat Sertoli cells were isolated with enzymatic hydrolysis. Exosomes were isolated from primary rat Sertoli cells, rat epididymis tissue, and human seminal plasma with polymer-based precipitation method. Exosomal microRNAs were quantified with qPCR. Inhibin-B was detected with enzyme immunoassay. The correlation analysis between microRNA and inhibin-B was evaluated with Spearman's correlation. RESULTS We screened 12 previously reported hypoxia-responsive microRNAs in the primary rat Sertoli cells and found that 4 exosomal microRNAs increased significantly in response to in vitro hypoxia treatment (P < .05). Of the 4 microRNAs, only miR-210-3p was upregulated in the rats with experimental varicocoele (P < .01). In the patients with varicocoele, we found that seminal exosomal miR-210-3p significantly increased in patients with grade II and III varicocoele (P < .01), and miR-210-3p negatively correlated with sperm count (P < .01) and seminal inhibin-B expression (r = -0.39, P < .01). For the 30 patients with microsurgical varicocelectomy, the operation notably decreased miR-210-3p (P < .01). DISCUSSION AND CONCLUSION Seminal exosomal miR-210-3p may be a novel, sensitive, and non-invasive biomarker of Sertoli cell damage in varicocoele.

BMC Urol 2018; 18:58. [PMID: 29879956 PMCID: PMC5992893 DOI: 10.1186/s12894-018-0350-7] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2016] [Accepted: 05/02/2018] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND We introduced and recreated a more consistent and effective experimental varicocele rat model by a new clip technique. METHODS A total of 40 rats were numbered and randomly assigned to 5 groups of 8 each, including sham surgery (Group I), conventional (Group II) and clip groups with 0.7, 0.8, 0.9 mm gap widths, respectively (Group III, IV, V). All of the rats in each group were sacrificed at 8 weeks after initial surgery, and the rats forming out with less than 1 mm diameter of left spermatic vein or no presence of the pampiniform plexus dilation were excluded from the experimental groups. The left spermatic vein (LSV) diameter, testicular weight, left kidney weight to body weight coefficients, kidney and testicular histology were determined. RESULTS The baseline mean diameter of the LSV in Group I, II and III was 0.22 ± 0.02, 0.23 ± 0.02 and 0.22 ± 0.03 mm, respectively (P = 0.7504). At 8 weeks after initial surgery, varicocele was successfully created in 6/8 (75%), 7/8 (87.5%), 3/8 (37.5%), 3/8 (37.5%) in GroupII-V, no varicocele was observed in Group I. In Group I, II and III, no pathological changes were observed and the left kidney weight to body weight coefficients showed no significant differences. The diameter of LSV was remarkably increased both in Group II and III compared to Group I (1.72 ± 0.13, 1.57 ± 0.19 and 0.25 ± 0.02, respectively), and Group II and III had a smaller testicular weight than the rats in Group I (1.67 ± 0.05, 1.62 ± 0.06, and 1.92 ± 0.12, respectively). CONCLUSIONS With a new clip technique, surgically inducing varicocele rat model becomes convenient and safe. This appears to improve the effectiveness of the model and this innovation may allow us to further understand the pathophysiology of varicocele.
