Badraoui R, Gargouri M, Brahmi F, Ben-Nasr H, Bahrini I, Soussi A. Protective effects of Juglans regia oil on lead acetate-induced reprotoxicity in rats: an antioxidant, histological and computational molecular study. JOURNAL OF THE SCIENCE OF FOOD AND AGRICULTURE 2025; 105:2515-2526. [PMID: 39542863 DOI: 10.1002/jsfa.14024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 09/29/2024] [Accepted: 10/29/2024] [Indexed: 11/17/2024]
Abstract
BACKGROUND Lead (Pb) is a metal that affects many body systems, primarily the male reproductive system. This study aimed to examine the phytochemical profiling and beneficial effects of Juglans regia oil (JRO) in alleviating lead-induced reprotoxicity-associated oxidative injury in rats. Adult male Wistar rats were randomly divided into four groups as follows: control group received no treatment, Pb group was exposed to 0.344 g kg-1 bw of Pb acetate, Pb + JRO group was co-treated with Pb plus walnut oil (0.9 g kg-1 bw) and JRO group received walnut oil only. RESULTS Pb-treated rats showed significantly decreased gonado-somatic index, count and viability of sperm. Testosterone levels decreased in Pb-treated animals. Besides, Pb disrupted the oxidative/antioxidative status, the plasmatic lipase activity and testicular Pb content. Furthermore, Pb produced testis histopathological features, especially cell degeneration, atrophy and tubular disarrangement. Co-treatment with JRO was found to be effective for recovering the increased testicular oxidative damage-associated histological features in the Pb group. This was supported by the in silico modeling results. CONCLUSION The in silico analyses revealed that JRO compounds bound androgen receptor and RAC-alpha serine/threonine kinase with high affinities, which together with pharmacokinetic properties and molecular interactions satisfactorily support the beneficial in vivo findings in the Pb + JRO group of rats. © 2024 Society of Chemical Industry.

Abstract
Calsyntenin-1 (Clst1) is a sensitive indicator of lead (Pb) toxicity in neural tissue. This study was designed to investigate the impact of lead exposure on Clst1 expression in PC12 cells and the mitigating effect of pea peptide 4 (PP4) on lead-induced neurotoxicity. Data showed that lead exposure, at varying doses and durations, disrupted the mRNA expression and protein levels of Clstn1 in PC12 cells. However, immunofluorescence results showed that treatment with PP4 significantly increased Clstn1 protein expression in the Pb + PP4 and PP4 groups compared to the Pb groups (P < 0.05). Lead exposure activates the JNK and p38 pathways; at the same time, PP4 treatment enhances ERK pathway activation and reduces JNK and p38 activation.

Protective effects of polysaccharide extracted from green alga Chaetomorpha linum against zinc and copper-induced testicular toxicity in male mice. Toxicol Mech Methods 2024; 34:897-907. [PMID: 38918930 DOI: 10.1080/15376516.2024.2361070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2024] [Revised: 05/22/2024] [Accepted: 05/23/2024] [Indexed: 06/27/2024]
Abstract
This study aimed to investigate the effects of copper (CuSO4) and zinc (ZnSO4) overload on male reproductive toxicity and the potential of a polysaccharide extracted from green alga Chaetomorpha linum (PS) in mitigating their toxicities. Adult male mice strain of 25 ± 2 g of weight was subdivided into eight groups. Group 1 served as control; group 2 received PS (200 mg/kg), and groups 3 and 4 received intraperitoneally zinc (60 mg/kg b.w) and copper (33 mg/kg b.w), respectively. Group 5 received both zinc (60 mg/kg b.w) and copper (33 mg/kg b.w), group 6 received zinc (60 mg/kg b.w) associated with PS (200 mg/kg), group 7 received copper (33 mg/kg b.w) associated with PS (200 mg/kg), and group 8 received zinc (60 mg/kg b.w) and copper (33 mg/kg b.w) associated with PS (200 mg/kg). Results suggested that ZnSO4 and CuSO4 significantly decreased the functional sperm parameters. Furthermore, extended exposure to these elements increased oxidative stress biomarkers, including malondialdehyde (MDA) as a measure of lipid peroxidation and advanced oxidation protein products (AOPP) indicating protein oxidative damage. This process also reduces the activity of antioxidant enzymes such as glutathione (GSH) and glutathione peroxidase (GPx), which neutralize and catalyze free radicals. Histopathological changes in mice testis were also studied. However, the co-treatments with PS significantly reduced these effects and promoted the reproductive parameters in male mice. In conclusion, PS exhibited protective effects against zinc and copper-induced reproductive toxicity, making it a potential adjuvant treatment for testicular toxicity.

Abstract
Lead is considered one of the most prevalent environmental and biologically hazardous toxicants among metallic elements. It severely affects human health and especially the male reproductive system by causing reproductive organ dysfunction leading to infertility. Natural dietary antioxidants are studied for their ability to ameliorate the cells' miscellaneous damage. The current study was designed to explore the effect of Vitis vinifera (Linn.) (grape) seed extract (GSE) on lead acetate (LA)-induced oxidative damage on testis and sperm quality in rats. Twenty-four male Wistar rats were allocated into four equal groups. Group I received distilled water; Group II received LA 50 mg/kg body weight (Bw); Group III received LA 50 mg/kg + GSE 200 mg/kg Bw; and Group IV received LA 50 mg/kg + GSE 400 mg/kg Bw (orally once a day for 28 days). After 28 days, levels of malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and reduced glutathione (GSH) were estimated in the testicular tissue. The cauda of the epididymis was used to study the characteristics of the sperm, such as sperm count, motility, viability, tail-coiled sperm, and morphology. The hematoxylin and eosin staining method was used to study histomorphology. Results revealed that LA induction significantly increased MDA concentration and decreased the levels of SOD, CAT, GPx, and GSH. It also reduced the weight of the testis and testosterone hormone levels, declined the quality of sperm, and increased morphologically abnormal sperm. Moreover, LA severely altered the histomorphology of the testis, such as atrophy of the seminiferous tubule, degeneration of germinal epithelium, and increased interstitial space, compared with the control group. In Groups III and IV, coadministration of LA with GSE reduced the MDA concentration, preserved the antioxidant enzyme system and testosterone hormonal levels, restored the sperm characteristics, reduced the abnormal sperm, and improved histomorphological alterations in the testis compared with the LA-induced group. In conclusion, GSE has a potent natural antioxidant that provides promising protection against LA-induced testicular oxidative damage on testis and sperm quality in rats.

Effectiveness of Withania frutescens root extract on testicular damage induced by lead acetate in adult albino rats. Reprod Toxicol 2023; 115:102-110. [PMID: 36535557 DOI: 10.1016/j.reprotox.2022.12.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2022] [Revised: 12/11/2022] [Accepted: 12/14/2022] [Indexed: 12/23/2022]
Abstract
Withania frutescens was used previously in traditherapy against poisoning, gastric ulceration, and dysentery treatments. Because no previous studies reporting on its therapeutic effects on male reproductive system and fertility disorders, this study aims to examine its effect on lead induced testicular damages as well as sperm count and hormonal status in rats. The present study is performed to determine their phytochemical compositions using GC-MS analysis, their antioxidant and anti-inflammatory activities in-vitro using spectrophotometry and then to estimate testosterone levels, sperm count, histopathological features, as well as spermatogenesis (TDI) and spermiogenesis (SPI) indices. The experiment is conducted for three months using four groups (Group A: control rats; Group B: exposed rats to lead-acetate; Group C: exposed rats to lead-acetate and 200 mg/kg of W. frutescens extract; Group D: treated rats with 200 mg/kg of W. frutescens extract). The obtained results show a total of 10 identified components from GC-MS analysis. Whereas a total phenolic content of 63.23 ± 3.82 GAE/g of extract, 25.16 ± 1.21 µg/mL of anti-free radical activity, and reducing power of 163.19 ± 6.01 µg/mL. A high anti-inflammatory activity is determined by hemolysis inhibition (IC50 =12.71 ± 1.06 µg/mL) and protein denaturation inhibition (IC50 =6.8 ± 1.23 µg/mL). Besides, lead exposure causes histological alterations in testis and decreases serum testosterone level, sperm count, and TDI and SPI indices. W. frutescens treated and co-treated animals showed no toxic effects throughout the experiment. However, it is found to improve testosterone level, increase sperm count, attenuate the testicular histopathological effect of lead, and increase TDI and SPI. These findings . these findings suggest that W. frutescens is a better source of bioactive compounds, which play an effective role against lead testicular damages. Furthermore, this natural extract can be utilized potentially in pharmaceutical and medicinal applications.

Abstract
Varicocele (VCL) is a pathological dilation of the venous pampiniform plexus of the spermatic cord and is also classified as male factor infertility. The current experiment aimed to examine the protective effect of Fumaria parviflora (FP), as a powerful antioxidant, against reproductive damage induced by VCL. In this experimental study, 32 male rats were randomly allocated into four groups, namely sham (simple laparotomy without additional intervention), FP (healthy rats administered 250 mg/kg FP), VCL + FP (underwent VCL and received 250 mg/kg FP), VCL (underwent VCL without receiving any treatment). The results showed that the number of Sertoli and germ cells were markedly reduced in the VCL group in comparison to the FP-treated and sham groups. The VCl + FP group had significantly higher serum levels of testosterone (T), FSH, and LH hormones than the VCL group. The quality and motility of spermatozoa were reduced in the VCL group compared with other groups (p ≤ 0.05). Moreover, our findings demonstrated that the administration of FP considerably enhanced the mRNA levels of CatSper-1 and -2, SF-1, 3β-HSD, 17β-HSD3, LHCGR, and FSHR (p ≤ 0.05). Based on the obtained results, treatment with FP is capable of preventing testicular dysfunction and elevating the concentration of hormones and some crucial genes, such as CatSper1 and 2, SF-1, 3β-HSD, 17β-HSD3, LHCGR, and FSHR that contribute to the spermatogenesis process.

Abstract
The current study investigates the potential alleviating activity of bulbs (B) and leaves (L) of Allium triquetrum aqueous extract (ATE) on repro-toxicity induced by lead acetate (Pb) in male Wistar rats administrated orally for 3 consecutive weeks. Eighteen groups of rats were divided into the control, Pb (500 mg/kg body weight/day), positive controls of B and L (2 g, 3 g, 4 g, 6 g/kg body weight/day), in addition to four mixtures of each of Pb-B (Pb-B1, Pb-B2, Pb-B3, Pb-B4) and Pb-L (Pb-L1, Pb-L2, Pb-L3, Pb-L4). The two extracts were subjected to phytochemical screening and HPLC analysis. Sperm characteristics were evaluated by CASA system, as well as the serum testosterone, testicular and epididymal levels of glutathione (GSH), glutathione peroxidase (GPx), and malondialdehyde (MDA). The phytochemical screening proved that bulbs' and leaves' extracts were rich in various compounds and the HPLC showed that leaves contain more tannins. Results revealed a significant decrease in the testicular and in the epididymal weights, sperm concentration, motility, testosterone, velocity, vitality, round cells, GSH, and GPx levels in the Pb-intoxicated rats compared to the control, with the exception of MDA concentration that was significantly increased. However, the co-administration of garlic extracts (Pb-B and Pb-L) exhibited a significant increase in all mentioned markers, except for the MDA level which was reduced. Likewise, Pb caused histological injuries in the testicular seminiferous of rats, while the co-administration of wild garlic has reduced such effect, especially in the higher doses. Both extracts of Pb-B and Pb-L have attenuated Pb toxicity in a dose-dependent manner. In conclusion, aqueous extracts of A. triquetrum have the potential to reduce Pb testicular injuries by boosting sperm characteristics and ameliorating oxidative stress markers.

Abstract
OBJECTIVES Lead exposure seriously impairs male reproductive function. The protective capacity of Pedalium murex leafy stem and fruit aqueous extracts against lead testicular toxicity is evaluated to find herbals drugs able to improve semen quality. METHODS Phytochemical screening were performed according to classical methods. Twenty four male rats were divided into four groups of six rats each and received the following treatments via oral route: distilled water; 0.2% lead acetate in drinking water; 0.2% lead acetate in drinking water with 400 mg/kg P. murex aqueous leafy stem extract; 0.2% leaded water with 400 mg/kg P. murex aqueous fruit extract. Treatments were administered for 70 days. Body and reproductive organs weights, sperm parameters and testicular histological sections of each group were examined. RESULTS Flavonoids, tannins, coumarins, alkaloids, and lignans were found in both extracts. Lead intoxication reduced sperm motility and count but increased the percentage of morphologically abnormal sperms. The germinal epithelium of seminiferous tubules histoarchitecture was disorganized by lead. The leafy stem extract was effective in reducing lead induced testicular disruption whereas fruit has not shown any beneficial effect. CONCLUSIONS P. murex leafy stem aqueous extract is effective against semen alterations caused by lead.

Abstract
The aim of the study was to investigate the protective effect of pyrrolidine dithiocarbamate (PDTC) against methotrexate (MTX)-induced testicular damage in rats. Forty Wistar albino male rats were divided into equally four groups: Control group (saline solution, IP), PDTC group (100 mg/kg PDTC,IP, 10 days), MTX group (20 mg/kg MTX, IP, single dose, on the 6th day) and MTX + PDTC group (100 mg/kg PDTC, IP, 10 days and 20 mg/kg MTX, IP, single dose, on the 6th day). After 10 days, testicular tissues were excised for morphometric, histological and immunohistochemical evaluations. Serum testosterone, follicle stimulating hormone (FSH), luteinizing hormone (LH) and prokineticin 2 (PK2) levels were determined. Body and testicular weights were measured. Testicular damage was assessed by histological evaluation. Nuclear factor kappa B (NFkB), nuclear factor erythroid 2 related factor 2 (Nrf2) and PK2 immunoreactivities were evaluated by HSCORE. Body and testicular weights, serum FSH, LH, testosterone levels, seminiferous tubule diameter and germinal epithelial thickness were significantly decreased in the MTX group. However, serum PK2 level, histologically damaged seminiferous tubules and interstitial field width were significantly increased. Additionally, there was an increase in NFkB and PK2 immunoreactivity, whereas there was a significant decrease in Nrf2 immunoreactivity. PDTC significantly improved hormonal, morphometric, histological and immunohistochemical findings. Taken together, we conclude that PDTC may reduce MTX-induced testicular damage via NFkB, Nrf2 and PK2 signaling pathways.

Abstract
BACKGROUND Lead (Pb) is an environmental pollutant causing serious health problems, including impairment of reproduction. Visnagin (VIS) is a furanochromone with promising antioxidant and anti-inflammatory effects; however, its protective efficacy against Pb toxicity has not been investigated. OBJECTIVE This study evaluated the protective effect of VIS on Pb reproductive toxicity, impaired steroidogenesis and spermatogenesis, oxidative stress and inflammation. METHODS Rats received VIS (30 or 60 mg/kg) and 50 mg/kg lead acetate for 3 weeks and blood and testes samples were collected. RESULTS Pb intoxication impaired the pituitary-testicular axis (PTA) manifested by the decreased serum levels of gonadotropins and testosterone. Pb decreased sperm count, motility and viability, increased sperm abnormalities, and downregulated the steroidogenesis markers StAR, CYP17A1, 3β-HSD and 17β-HSD in the testis of rats. VIS significantly increased serum gonadotropins and testosterone, alleviated sperm parameters and upregulated steroidogenesis. In addition, VIS decreased pro-inflammatory cytokines, testicular lipid peroxidation and DNA fragmentation, downregulated Bax, and enhanced antioxidants and Bcl-2. CONCLUSION These results demonstrate the protective effect of VIS against Pb reproductive toxicity in rats. VIS improved serum gonadotropins and testosterone, enhanced steroidogenesis and spermatogenesis, and attenuated oxidative injury, inflammation and apoptosis. Therefore, VIS is a promising candidate for the protection against Pb-induced reproduction impairment.

Adesiyan GO, Talabi TO, Kale OE, Ogundare TF. Ethyl acetate fraction of Spathodea campanulata ( Bignoniaceae) attenuates lead acetate induced testicular toxicity in male Wistar rats. JOURNAL OF COMPLEMENTARY & INTEGRATIVE MEDICINE 2021; 19:19-26. [PMID: 33979900 DOI: 10.1515/jcim-2019-0289] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/10/2020] [Accepted: 01/02/2021] [Indexed: 11/15/2022]
Abstract
OBJECTIVES The use of Spathodea campanulata in folklore medicine for the management of reproductive disorders has been poorly reported. We sought to investigate the protective potential of the ethyl acetate fraction of S. campanulata stem bark extract (EFSC) on lead acetate-induced (LA) testicular toxicity in male rats. METHODS Animals during a 28 days treatment received dimethyl sulfoxide (DMSO, 0.1%), LA (20 mg/kg), and EFSC (200 mg/kg). Others received EFSC only (100, 200, and 400 mg/kg) or vitamin E (100 mg/kg) 1 h prior to LA (20 mg/kg) administration. RESULTS LA administration decreased sperm counts and motility by 36.39 and 40.69% respectively in rats. Also, LA-untreated rats showed elevated malondialdehyde (MDA) and decreased total proteins in testis (260, 33%) and epididymis (62, 29%) respectively. However, EFSC (100, 200, or 400 mg/kg) administrations improved sperm morphological characteristics as well as antioxidant status in LA-treated rats. EFSC (400 mg/kg) showed improved testis seminiferous tubules that were almost normal in the LA-treated rats. Further, EFSC contains a high 9-octadecenoic acid methyl ester. CONCLUSIONS Overall, evidence by LA-induced testicular toxicity, EFSC provides chemopreventive roles via antioxidant mechanisms.

Abstract
OBJECTIVES Lead primarily affects male reproductive functions via hormonal imbalance and morphological damage to the testicular tissue with significant alteration in sperm profile and oxidative markers. Though, different studies have reported that Cocos nucifera L. oil has a wide range of biological effects, this study aimed at investigating the effect of Cocos nucifera L. oil on lead acetate-induced reproductive toxicity in male Wistar rats. METHODS Twenty (20) sexually matured male Wistar rats (55-65 days) were randomly distributed into four groups (n=5). Group I (negative control)-distilled water orally for 56 days, Group II (positive control)-5 mg/kg bwt lead acetate intraperitoneally (i.p.) for 14 days, Group III-6.7 mL/kg bwt Cocos nucifera L. oil orally for 56 days and Group IV-lead acetate intraperitoneally (i.p.) for 14 days and Cocos nucifera L. oil for orally for 56 days. Rats were sacrificed by diethyl ether, after which the serum, testis and epididymis were collected and used for semen analysis, biochemical and histological analysis. RESULTS The lead acetate significantly increases (p<0.05) testicular and epididymal malondialdehyde (MDA) levels, while a significant reduction (p<0.05) in sperm parameters, organ weight, testosterone and luteinizing hormone was observed when compared with the negative control. The coadministration of Cocos nucifera oil with lead acetate significantly increases (p<0.05) testosterone, luteinizing hormone, sperm parameters and organ weight, with a significant decrease (p<0.05) in MDA levels compared with positive control. Histological analysis showed that lead acetate distorts testicular cytoarchitecture and germ cell integrity while this was normalized in the cotreated group. CONCLUSIONS Cocos nucifera oil attenuates the deleterious effects of lead acetate in male Wistar rats, which could be attributed to its polyphenol content and antioxidant properties.

Cryobiology 2021; 98:17-24. [PMID: 33460590 DOI: 10.1016/j.cryobiol.2021.01.008] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2020] [Revised: 01/10/2021] [Accepted: 01/11/2021] [Indexed: 11/28/2022]
Abstract
During cryopreservation, spermatozoa are exposed to chemical or physical stress that has adverse effects on the quality of mammalian spermatozoa. Recently, much attention has been paid to environmental contaminants (ECs) in livestock, because of their detrimental effects on livestock productivity and fertility. ECs like diazinon (DZN) and lead acetate (LA) are considered ubiquitous and induced oxidative stress, which decreases spermatozoa quality. Since Ferulago angulata extract (FAE) has antioxidant properties, the present study investigated the effect of FAE supplementation in a freezing extender, in the presence or absence of DZN + LA, during cryopreservation, on the quality and fertility ability of buck spermatozoa after thawing. Pooled ejaculates were diluted with a freezing extender and supplemented with FAE (0.002%, w/v) in the presence or absence of DZN (100 μM) + LA (12.5 μM). Post-thaw spermatozoa parameters, ROS production, fertilization ability, and developmental competence of oocytes inseminated with FAE/DZN + LA treated spermatozoa were calculated. The results demonstrated that FAE improves cryopreserved spermatozoa motility, viability, membrane integrity, fertilizability, and developmental competence, and reduced spermatozoa ROS production in the presence or absence of DZN + LA. Besides, FAE significantly restored the adverse effects of DZN + LA exposure during cryopreservation on inner cell mass (ICM) count, trophectoderm (TE) cell count, total cell number (TCN), and the ratio between ICM to TCN. In conclusion, FAE on its own resulted in an improvement in the buck spermatozoa's quality and fertility. Therefore, the addition of FAE, as a natural antioxidant to buck semen extender, can increase spermatozoa cryotolerance and post-thaw resistance even when exposed to ECs.

Chrysin protects against testicular toxicity caused by lead acetate in rats with its antioxidant, anti-inflammatory, and antiapoptotic properties. J Food Biochem 2020; 45:e13593. [PMID: 33368351 DOI: 10.1111/jfbc.13593] [Citation(s) in RCA: 42] [Impact Index Per Article: 8.4] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 11/10/2020] [Accepted: 12/04/2020] [Indexed: 12/11/2022]
Abstract
In the present study, the protective effects of chrysin (CHR) against testicular damage caused by lead acetate (PbAc) were examined. In this way, 30 min after rats were given 25 and 50 mg/kg/b.w CHR orally for seven consecutive days, 30 mg/kg/b.w PbAc was administered orally. In biochemical analysis of testicular tissue, it was found that PbAc-reduced antioxidant parameters [glutathione peroxidase (GPx), glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT)], while it increased lipid peroxidation, inflammatory markers [nuclear factor kappa-B (NF-κB), cyclooxygenase-2 (COX-2), prostaglandin E2 (PGE-2), and inducible nitric oxide synthase (iNOS)], and 8-hydroxy-2'-deoxyguanosine (8-OHdG). In the immunohistochemical examination, it was determined that PbAc increased the expression of tumor necrosis factor-α (TNF-α) and caspase-3. Accordingly, PbAc was found to cause a decrease in sperm motility and an increase in the percentage of dead sperm. However, it has been observed that CHR relieves oxidative stress due to its antioxidant properties, thus protecting against inflammation and apoptosis. It also allowed the CHR sperm parameters to return to control group levels. The results revealed that CHR could be a natural substance to be used in Pb-induced testicular toxicity. PRACTICAL APPLICATIONS: Lead (Pb) is an important environmental contaminant heavy metal. Pb is believed to reduce fertility in men. Oxidative stress plays a significant role in the damage caused by Pb to testicular tissue. CHR is an antioxidant substance that occurs naturally in various plants and has various pharmacological properties. In the present study, it was investigated whether CHR has a protective effect against testicular toxicity induced by PbAc. The results revealed that in rats, CHR protects the testicular tissue from PbAc toxicity by showing antioxidant, anti-inflammatory and anti-apoptotic effects, thus bringing sperm parameters closer to normal.

Abstract
INTRODUCTION Lead (Pb) is an environmental toxic metal that threatens human health. Umbelliferone (UMB) is a coumarin with known medicinal and protective properties against cytotoxicity. This study explored the ameliorative effect of UMB against Pb-induced testicular toxicity in rats, focusing on steroidogenesis, oxidative stress and inflammation. MATERIALS AND METHODS Rats received lead acetate (50 mg/kg) and UMB (25, 50 or 100 mg/kg) via oral gavage for 4 weeks. RESULTS Pb-intoxicated rats exhibited testicular tissue injury and decreased serum levels of LH, FSH and testosterone. The count, viability, motility and normal morphology of the sperms were decreased accompanied with downregulated steroidogenesis markers in Pb-induced group. UMB prevented testicular injury, increased serum levels of LH, FSH and testosterone, upregulated steroidogenesis markers and improved the semen quality. In addition, UMB attenuated oxidative stress and oxidative DNA damage, downregulated the expression of pro-inflammatory mediators and Bax, boosted antioxidant defenses and Bcl-2, and upregulated Nrf2/HO-1 signaling in Pb-intoxicated rats. CONCLUSION UMB prevents Pb-induced testicular injury by suppressing oxidative damage, inflammation and cell death, and boosting antioxidant defenses, Nrf2/HO-1 signaling and pituitary-gonadal axis. Thus, UMB may represent a protective and cost-effective agent against Pb testicular toxicity, pending further investigations to elucidate other underlying mechanisms.

Abstract
The study's aim was to explore the effect of venlafaxine, valsartan, and pramipexole on spermatogenesis. It was hypothesized that these drugs may affect the male fertility because of their long-term use in treatment of depression, hypertension, and Parkinson's diseases. Male rats were given venlafaxine, valsartan, and pramipexole at low- and high-dose levels orally once daily for 10 weeks. Testosterone (25 mg/kg) was given as a standard via an intramuscular route once weekly. Rats were sacrificed after blood collection by cardiac puncture, and testes were removed. Sperm parameters were examined from spermatozoa of the cauda epididymis, and testes were treated for histopathological analysis. Results showed nonsignificant effect of venlafaxine on the sperm count, whereas a decreased sperm count was noted in all the treatment groups as compared to that of the control except valsartan at a low dose, which significantly (p < 0.001) raised the sperm count (96.26 ± 2.4) in reference with the control value (49.13 ± 2.3). Treatments had variable effects on total sperm motility and morphological parameters, but valsartan at a low dose showed maximum sperm motility (71.55 ± 0.7) among all. DNA integrity of spermatozoa remained intact in all groups. Luteinizing hormone and follicle-stimulating hormone levels decreased, and testosterone levels increased in all treatment groups as compared to control values, which indicate fertility. Histopathology revealed normal texture of testes with venlafaxine and valsartan, but testicular damage occurred with high-dose pramipexole. It is concluded that the use of venlafaxine, valsartan, and pramipexole at a low dose is devoid of any harmful effect on spermatogenesis, whereas pramipexole at a high dose adversely affect it.

Abstract
Fumaria species, commonly known as fumitory or earth smoke, are considered weeds in many regions. However, several Fumaria species have long been used in folk medicine, such as F. capreolata L., F. densiflora DC., F. indica (Hausskn.) Pugsley, F. officinalis L., F. parviflora Lam., and F. vaillantii Loisel. as well. The ethnobotany, phytochemistry, and pharmacology of 24 Fumaria species have been investigated. Phytochemical studies on Fumaria species revealed the presence of numerous alkaloids, flavonoids, saponins, and terpenoids. Phthalideisoquinolines (PTIs), protoberberines, and spirobenzylisoquinolines (SBIs) are the major alkaloids in the genus Fumaria. The plants biosynthesize a diverse group of biologically active isoquinoline alkaloids, and these may help to explain the use of various Fumaria species in folk medicine. Pharmacological studies revealed a broad spectrum of bioactivities such as hepatoprotective, anti-inflammatory, antimicrobial, antioxidant, and antitumor activities. We found 159 articles published from 1969-2019 by searching the keyword "Fumaria" using databases such as SciFinder, Google Scholar, and PubMed. Based on our reading of these papers, Fumaria species appear to be a source of bioactive isoquinoline alkaloids and ethnomedicines. The lack of studies on pharmacological mechanisms, pharmacokinetics, clinical efficacy, quality control, and toxicology are discussed in this review. There is great potential for broader medicinal applications of this genus.

Abstract
The aim of this study was to examine the effect of the secondary biological treatment plant effluent administration on the kidneys, urinary bladder, and testis of Wistar rats in relation to lead (Pb) and cadmium (Cd) accumulation, since such an effluent is used for irrigation of edible plants. Male Wistar rats, randomly assigned into 5 groups, were treated with domestic sewage effluent (DSE) for 24 months. Cadmium and lead concentrations in the DSE, rats' tissues, and urine were estimated by means of atomic spectroscopy. Lead was rapidly accumulated in high amounts in rats' kidney and to a lesser extent in the testis whereas Cd concentration was raised in all tissues examined. Deposition of Cd and Pd in the kidney of the rats resulted in profound damage over time. The results showed that long-term administration to DSE as drinking water exposes living organisms to urogenital stress related to heavy metal concentration and pH of the effluent.

Abstract
Introduction: Lead is a multiple organ toxicant and an oxidative-stress inducer. The effect
of Costus afer on metal- induced male reprotoxicity has not
been previously carried out, hence this study. The present study
investigates the protective effect of Costus afer aqueous
leave extract on lead- induced reproductive damages in male albino Wistar
rats. Methods: Adult male albino Wistar rats were weighed and separated into five groups of
five rats each. Groups 1 & 2 served as normal and toxic controls
receiving deionized and leaded
(CH3COO)2Pb.3H2O and water
respectively. Groups 3, 4 and 5 were given 750, 1500 and 2250mg/kg of
Costus afer orally, respectively while receiving
Pb2+ water ad libitum for 28 days. Results: The reproductive and antioxidant parameters obtained from the result served
as scientific evidence in the study. The result showed non-significant
changes in the absolute and relative weights of epididymis and testes in the
Pb Group versus the control. Significant increases were
recorded in the sperm analysis, blood lead (7.9±1.02;
1.1±0.01) level (BLL), luteinizing hormone (LH)
(8.5±1.4:5.5±0.4), and a decrease in follicle stimulating
hormone (FSH) (4.5±2.6:6.5±1.65), with non-significant changes
in testosterone (TET) (1.3±0.00:1.6±0.2) in the Pb group
compared to the control. Conclusion: The treatment with Costus afer exhibited dose-dependent
significant changes in testicular oxidative stress, hormonal, sperm analysis
and histopathological changes induced by lead. Aqueous leaves extract of
Costus afer may be protective against lead induced
testicular damage.

R S, S AD. Protective effect of Abutilon indicum against lead-induced reproductive toxicity in male Wistar rats. J Cell Biochem 2019; 120:11196-11205. [PMID: 30714201 DOI: 10.1002/jcb.28395] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2018] [Revised: 12/26/2018] [Accepted: 01/09/2019] [Indexed: 01/24/2023]
Abstract
Despite ample literature on the toxic impact of lead on the environment and health, the exact mechanism of pathogenesis/toxicity is not clearly known. Because it is well established that lead induces oxidative stress, it is assumed that exposure to antioxidants may reduce the toxic impact of lead. In this study, we evaluated the impact of coadministration of the methanolic root extract of a plant Abutilon indicum (50, 100, 200 mg kg -1 b.wt.) in mitigating the toxic impact of lead on the reproductive system of rats. In brief, Wistar rats were exposed to lead acetate in drinking water with or without coadministration of plant root extract and compared with that of control animals. After 45 days of exposure as outlined above, the animals were killed and the reproductive toxicity was assessed by sperm parameters, hormone and antioxidant enzyme assays, and testis histopathology. Significant reduction in testis weight, sperm count, testosterone levels, and antioxidant enzymes levels such as Superoxide Dismutase, Catalase, and Glutathione peroxidase was seen in lead-treated animals, confirming the toxic impact. The coadministration of A. Indicum (100 and 200 mg kg -1 b.wt.) was found to bring the studied parameters close to the levels seen in untreated (control) animals. Our findings are indicative of the protective nature of A. Indicum against lead-induced reproductive toxicity in a dose-dependent manner. However, further characterization of the root extract is required to elucidate the probable mechanism of protection.

Involvement of mitochondrial pathway in environmental metal pollutant lead-induced apoptosis of chicken liver: perspectives from oxidative stress and energy metabolism. ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH INTERNATIONAL 2017; 24:28121-28131.

Abstract
This study aimed to investigate the possible mechanisms of environmental metal pollutant lead (Pb)-induced apoptosis in chicken. Forty 8-day-old healthy chickens were randomly assigned to two groups (n = 20/group) after raising standard commercial diet and drinking water for 1 week: including control group and Pb group ((CH3COO)2Pb 350 mg/L of drinking water); the chickens were given euthanasia and collected livers at 90 days. A significant increase of apoptosis rate were found in Pb group and Pb induced obvious ultrastructural changes of chicken liver. The mRNA levels of glycometabolism key enzymes were significantly lower in Pb group than those in controls. Higher levels of malondialdehyde (MDA) and nitric oxide (NO) were observed in Pb group; the activities of antioxidant enzymes and ATPases were significantly lower in Pb group than those in controls, while the inducible nitric oxide synthase (iNOS) activity was on the contrary. The mRNA and protein levels of pro-apoptotic genes were all lower in Pb group than those in controls. Altogether, Pb-induced mitochondrial swelling and nuclear chromatin condensation, oxidative stress, energy metabolism disorder, thereby lead to apoptosis via mitochondrial pathway in chicken liver, suggesting that Pb-induced mitochondrial pathway apoptosis plays an important role in the mechanisms of Pb cytotoxicity to chicken liver.

Abstract
Lead affects multiple organ systems including testis. We investigated the effects of ferulic acid (FA) on lead-induced oxidative stress and spermatogenesis suppression in rats. Animals received lead acetate (500 mg/L in drinking water) and/or FA (50 mg/kg, i.g.) for eight weeks. Lead increased testicular malondialdehyde (MDA) and nitrite levels and decreased glutathione (GSH) content and catalase (CAT) activity. Lead decreased testis weight and testosterone level. Sperm parameters decreased in lead group. FA ameliorated the decreased testis weight, serum testosterone as well as sperm count, viability, motility and normal morphology in lead group. FA improved antioxidant capacity as well as sperm count, viability, motility and normal morphology. FA decreased Johnsen's mean testicular biopsy score (MTBS) criteria by restoring degeneration, atrophy and tubular disarrangement. FA also normalised spermatogonia, spermatocytes and spermatids numbers in lead group and led to increases in number of Leydig and Sertoli cells. FA showed beneficial effects in lead-induced testicular oxidative stress and spermatological disorders, through inhibiting lipid peroxidation and enhancing antioxidant defence systems. The positive effects of FA on Leydig cells may be involved in restoring testosterone levels in lead group. FA can be considered a potential candidate to protect testis against the deleterious effect of lead intoxication.

Abstract
In recent years, the use of the antioxidant in reducing heavy metal toxicities has increased worldwide. Curcumin has been reported to have a strong antioxidant activity. In this study, we investigated the protective effects of curcumin on lead acetate-induced testicular damage in rats. The sample used 40 male rats divided into 5 groups: negative control (rats were given daily with corn oil); positive control (rats were given daily with lead acetate 50 mg/kg BW orally once in a day for 35 days); and the treatment group (rats were given the curcumin 100 mg, 200 mg, and 400 mg/kg BW orally once in a day for 40 days, and on the 5th day, were given lead acetate 50 mg/kg BW one h after the curcumin administration). After 40 days, levels of malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GPx) in testicular tissue, and sperm count, motility and viability in the epididymis were measured in rats. Testis samples were also collected for histopathological studies. Results showed that lead acetate administration significantly decreased the SOD, GPx, and increased MDA levels. Lead acetate also decreased the sperm count, motility, viability, and altered histopathological testis (testicular damage, necrosis of seminiferous tubules and loss of spermatid) compared to the negative control. However, administration of curcumin significantly improved the histopathological in testis, increased the sperm count, motility, viability, and also significantly increased the SOD, GPx, and decreased MDA in testis of lead acetate-treated rats. From the results of this study we concluded that the curcumin could be a potent natural product provide a promising protective effect against lead acetate induced testicular toxicity in rats.

Abstract
Zearalenone (ZEA) mainly injures the reproductive system of mammals. In the present study, we aimed to explore the mechanism by which zinc inhibits ZEA-induced reproductive damage in KK-1 cells for the first time. The results shown that both zinc sulfate and zinc gluconate addition increased the intracellular zinc concentration and influenced the expression of zinc transporters (Slc30a1 and Slc39a1) in a time-dependent manner. Co-incubation of zinc with ZEA significantly reduced the ZEA-induced reactive oxygen species and malondialdehyde elevation by promoting the transcription of Mtf1 and Mt2. Meanwhile, two different zincs inhibited the ZEA-induced loss of mitochondrial membrane potential and elevation of late-stage apoptosis via activating the mitochondrial apoptotic pathway by recovering the mRNA and protein expression of pro-apoptotic genes (Bax, Casp3, Casp9). Zinc also recovered cells from S-phase cell cycle arrest. In addition, both of them promoted the ZEA-induced estrogen production but regulated the expression of steroidogenic enzymes (Star, Cyp11a1, Hsd3b1, Cyp17a1) in different way. All these results indicated that zinc could inhibit the reproductive toxicity of ZEA.

Abstract
This study was realized to investigate the possible beneficial effect of thymoquinone (TQ), the major active component of volatile oil of Nigella sativa seeds, against lead (Pb)-induced inhibition of rat testicular functions. Adult rats were randomized into four groups: a control group receiving no treatment; a Pb group exposed to 2000 parts per million (ppm) of Pb acetate in drinking water; a Pb-TQ group co-treated with Pb (as in Pb group) plus TQ (5 mg/kg body weight (b.w.)/day, per orally (p.o.)); and a TQ group receiving TQ (5 mg/kg b.w./day, p.o.). All treatments were for 5 weeks. No significant differences were observed for the body weight gain or for relative testes weight among the four groups of animals. Testicular Pb content significantly increased in metal-intoxicated rats compared with that in control rats. TQ supplementation had no effect on this testicular Pb accumulation. Interestingly, when coadministrated with Pb, TQ significantly improved the low plasma testosterone level and the decreased epididymal sperm count caused by Pb. In conclusion, the results suggest, for the first time, that TQ protects against Pb-induced impairment of testicular steroidogenic and spermatogenic functions. This study will open new perspectives for the clinical use of TQ in Pb intoxication.
