Different forms of Aluminium (Al) are environmental xenobiotics that induce free radical–mediated cytotoxicity and reproductive toxicity. Vitamin E ( α-tocopherol) is an antioxidative agent that has been reported to be important for detoxification pathways. This study was thus aimed at elucidating the protective effects of vitamin E towards aluminium toxicity on the histology of the rat testis. Al (5 mg/kg body weight) was administered intraperitoneally in 2 ml saline, either alone or immediately before vitamin E (500 mg/kg body weight), at a different point of abdomen, and the alterations in the testis tissue were analyaed histologically. Seven treated animals were sacrificed for each group, with the testes removed and examined histologically. In the Al-treated group, the germinal epithelium of the seminiferous tubules was thinner in places and spermatids were almost absent; sperm numbers were low and there were no sperm in the lumen. In the Al plus vitamin E rats, there were large numbers of spermatids and sperm in the seminiferous tubule lumen. In the vitamin E alone group, a normal histology was seen. Electron microscopically, in the Al-treated group there were irregularities in the nuclear membrane, some damaged mitochondria, a decrease in the number of ribosomes, and an increase in the number of lysosomes in the sertoli cell cytoplasm. In the primary spermatocyte cytoplasm, there was an increase in the rough endoplasmic reticulum. In the Al plus vitamin E group, the spermatogeneic cells and the sertoli cell cytoplasm showed an almost normal appearance. The ultrastructure of the testis in the vitamin E alone group showed a normal appearance. In conclusion, vitamin E antagonizes the toxic effects of Al at the histological level, thus potentially contributing to an amelioration of the testis histology in the Al-treated rats. The associated biochemical parameters merit further investigation.

The aim of this study was to evaluate the protective effects ofGinkgo biloba(GB) against testicular damage and oxidative stress as well as caudal sperm indices in a cisplatin- (CIS-) induced rodent model. Adult male Wistar rats were given vehicle, single i.p. dose of CIS alone (10 mg/kg), GB alone (200 mg g/kg every day for five days), or single dose of CIS followed by GB (50, 100, or 200 mg/kg every day for five days). On day 6, after the first drug treatment oxidative and apoptotic testicular toxicity was evaluated. CIS-treated rats displayed decreased weights of testes and epididymis as well as caudal sperm count and motility. This reproductive toxicity was accompanied with increased germ-cell degeneration in seminiferous tubules and increased germ-cell apoptosis, increased testicular MDA levels and MPO activity, and decreased SOD and CAT activities in testes. Intensive expressions of COX-2, iNOS, and NF-κB p65 in testicular tissues were detected in CIS-treated group. Oral GB administrations at all doses to CIS-treated rats effectively alleviated all of the CIS-induced toxicity in reproductive system. The present results provide further insights into the mechanisms of protection against CIS-induced reproductive toxicity and confirm the essential antioxidant potential of a GB extract.

1 Carbofuran was administered orally to adult male rats at dose levels of 0.1, 0.2, 0.4 or 0.8 mg kg -1 body weight, 5 d wk-1 for 60 days. A dose dependent decrease was observed in body weight of rats treated with 0.2-0.8 mg carbofuran kg -1 body weight 2 A significant decrease in the weight of epididymides, seminal vesicles, ventral prostate and coagulating glands was observed at various test doses of carbofuran except at the lowest dose. 3 Decreased sperm motility, reduced epididymal sperm count along with increased morphological abnormali ties in head, neck and tail regions of spermatozoa were observed in rats exposed to 0.2, 0.4, or 0.8 mg carbo furan kg-1 body weight. 4 In addition, significant alterations were observed in the activities of marker testicular enzymes viz. sorbitol dehydrogenase (SDH), glucose-6-P-dehydrogenase (G6PDH) (decreased), lactate dehydrogenase (LDH) and γ-glutamyl transpeptidase (γ-GT) (increased) depending on dose. 5 Histologically, the results indicated the toxicity of carbo furan on testes depending on dose. The changes pre dominantly consisted of moderate oedema, congestion, damage to Sertoli cells and germ cells, along with the accumulation of cellular debris and presence of giant cells in the lumen of a few seminiferous tubules which showed disturbed spermatogenesis with the higher doses of carbofuran. 6 These observations determined a no effect level dose of 0.1 mg kg-1 body weight of carbofuran on the biochemi cal and morphological indices studied for male repro ductive toxicity assessment in the rat model. The results of the present study provide first hand information on the reproductive toxicity of carbofuran in male rats.

Usage of electronic gadgets like microwave oven is increasing day by day that heats the food by exposing it to electromagnetic radiations which has many hazardous effects on human health including fertility. Aim: To find the effects of microwave oven exposed diet on basal lamina of seminiferous tubules of mice alongwith protective effects of Mentha piperita and melatonin on the same tissue. Study Design: Randomized control trial. Methodology: Adult male mice (n=32) were divided into four groups. Control group (G1) received standard pellets prepared for mice. Second group (G2) was given mice pellets exposed to microwave oven. Third group (G3) received Mentha Piperita leaf extract along with mice pellets exposed to microwave oven and the fourth group (G4) received oral melatonin along with pellets exposed to microwave oven. Later their testicular tissue was removed for histological examination while basal lamina disruption was assessed by scoring. Data analyzed by SPSS 22.0v. Results: In group G2, there was slight disruption in the basal lamina in 75% of the cases while in experimental group G3, there was slight disruption of basal lamina only in 12.5% of the cases. However, in group G4, only 25% specimen had slight disruption of basal lamina Conclusion: It was concluded that microwave oven exposed diet produced severe disruption of basal lamina in group G2 that decreased in Mentha piperita and melatonin treated groups. However, Mentha piperita treated group produced better results than melatonin treated group. Keywords: Mice, Testis, Basal Lamina, Mentha piperita and Melatonin

Both aluminium and ethanol are pro-oxidants and toxic. Uncontrolled use of aluminium and increasing trends of ethanol consumption in India increased the chance of coexposure to aluminium and ethanol. There are possibilities, that both of them follow common mechanisms to produce reproductive toxicity. The present study was planned to identify the effects of aluminium administration on the microscopic structure of ovary and to clarify any possible protection conferred by the concomitant administration of ethanol. Sixteen female rats divided into one control and three experimental groups exposed to aluminium (4.2mg/kg body weight) and ethanol (1gm/kg body weight) for 3 months. After the exposure period, ovaries were processed for light microscopic examination. Ovary showed significant atretic follicles with degenerated ova and vacuolation. Rupture of zona pellucida in oocyte seen in aluminium treated animals. Ethanol treated group showing absence of growing follicles, increased large corpora lutea. Dilated and congested vessels were observed in the growing follicle. The effects of combined administration of aluminium and ethanol treated groups showed with acute degeneration of growing follicles, with desquamation of pyknotic granulosa cells and degenerated oocyte. Multiple vacuoles of degenerated granulosa cells with dilated congested vessels and edema seen. Hyaline material seen inside the degenerating follicles. It has been suggested that the ethanol induced augmentation of impacts of aluminium on the Ovary.

Abstract Considering that the involvement of reactive oxygen species (ROS) has been implicated in the toxicity of various pesticides, this study was designed to study the ameliorative effect of Vitamin E (100 mg/kg body weight) on mice (25 - 30 mg) treated with diazinon (32.5 or 16.25 mg/kg body weight) organophosphate insecticide for 14 days. Subchronic DZN exposure and the protective effects of vitamins E (vitE) were evaluated for their effects on haematological indices, the enzymes concerning liver damage [plasma alanine aminotransferase (ALT), aspartate aminotaransferase (AST), alkaline phosphatise (AIP), and some parameters of kidney function (urea and creatinine) in mice. Additionally, the histopathological changes in liver and kidney tissue were examined. The high dose of diazinon (DZNH) decreased the body weight significantly at the end of experiment. Additionally, the liver and kidney were examines for histopathological changes. The high dose of diazinon decreased body weight significantly. Moreover, there was a statistically significant decrease in haemoglobin (Hb), red blood cell (RBC) and hematocrit (Hct) in diazinon-treated mice compared to controls. This decrease was partially remedied in the diazinon-treated group that also received vitE. Damage in the liver and kidney tissues was also evident as elevated plasma ALT, AST, ALP, urea and creatinine. VitE partially counteracts the toxic effect of DZN and repairs tissue damage in the liver and kidney, especially when supplemented to 1/4 LD50 intoxicated animals. Histopathological changes in liver and kidney were observed only in 32.5 mg/kg DZN given group. These results suggest that the effects of DZN are dose dependent. No pathological findings were observed in vitE + DZN treated groups. According to the present study, we conclude that vitE can reduce the detrimental impacts of diazinon on haematological indicies, as well as liver and kidney function.

This study investigated the reproductive toxicity of methylmercury (MeHg) and Aroclor (Sigma-Aldrich), alone or in combination, following exposure of prepubertal male rats considering the chromatoid body (CB) as a potential target. The CB is an important molecular regulator of mammalian spermatogenesis, primarily during spermatid cytodifferentiation. Male Wistar rats were exposed to MeHg and/or Aroclor , according the following experimental design: control group, which was administered in corn oil (vehicle) only; MeHg-treated group, which was administered 0.5mg kg−1 day−1 MeHg; Aroclor-treated group, which was administered 1mg kg−1 day−1 Aroclor; Mix-LD, group which was administered a low-dose mixture of MeHg (0.05mg kg−1 day−1) and Aroclor (0.1mg kg−1 day−1); and Mix-HD group, which was administered a high-dose mixture of MeHg (0.5mg kg−1 day−1) and Aroclor (1.0mg kg−1 day−1). MeHg was diluted in distilled water and Aroclor was made up in corn oil (volume 1mL kg−1). Rats were administered the different treatments from PND23 to PND53 by gavage, . The morphophysiology of CBs was analysed, together with aspects of steroid hormones status and regulation, just after the last treatment on PND53. In addition, the long-term effects on sperm parameters were assessed in adult animals. MeHg exposure increased mouse VASA homologue (MVH) protein levels in seminiferous tubules, possibly affecting the epigenetic status of germ cells. Aroclor produced morphological changes to CB assembly, which may explain the observed morphological defects to the sperm flagellum and the consequent decrease in sperm motility. There were no clear additive or synergistic effects between MeHg and Aroclor when administered in combination. In conclusion, this study demonstrates that MeHg and Aroclor have independent deleterious effects on the developing testis, causing molecular and morphological changes in CBs. To the best of our knowledge, this is the first study to show that CBs are targets for toxic agents.

The health effects of bisphenol A (BPA) have become a great concern in recent years. In this study, the reproductive toxicity of BPA was investigated. Male CD-1 mice were orally administrated with BPA (0, 100, 300 and 600 mg kg−1 body weight) for 56 consecutive days. Results showed that relative testis weight to total body weight was significantly lower in the high-dose group ( p < 0.01, p < 0.05). Microscopic examination under light and transmission electron microscopes showed disorders of spermatogenesis after BPA exposure, including rough basal lamina of seminiferous tubules and damage of tight junctions between Sertoli cells. Further study by terminal-deoxynucleoitidyl transferase–mediated nick end labelling assay showed a significant induction of apoptosis in the testis tissue of the BPA groups ( p < 0.01). Immunohistochemical study found that the expression of androgen-binding protein (ABP) was significantly decreased in BPA-treated mice ( p < 0.01). Our results indicated that impairment of the basal lamina of seminiferous tubules and tight junctions may contribute to BPA-induced cell injury. A decrease in the level of ABP could be the possible mechanism for the reproductive toxicity of BPA. These findings provided direct evidence and novel insight into the reproductive toxicity of BPA and may have implications for understanding the toxicity of other endocrine disruptors.

ABSTRACTIt has been proved that Benzo(a)pyrene (B[a]P) is mutagenic in somatic cells, whereas the adverse effect of BaP on male reproduction remains unclear. To investigate whether it can pass through the blood-testis barrier (BTB) and its potential reproductive toxicology and molecular mechanisms, mice were exposed to B[a]P (there are two doses, that is 13mg/kg body weight and 26 mg/kg body weight; three times per week) during 6 weeks and sacrificed 6 weeks after the final exposure to obtain B[a]P-exposed testis, blood and others. Electron microscopy analysis was performed to confirm whether the integrity of BTB and the ultra-structure changes in testes of B[a]P treated mice, which showed that the integrity of the BTB was disrupted, accompanied with the structure of sertoli cells seriously damaged, including the integrity of the nuclear membrane of the sertoli cells impaired and the basement membrane of the seminiferous tubules disrupted. X-ray imaging in vitro told us that BaP can overgo the BTB and gathered in the testis of mice. We found the significantly decreased expression of ZO-1, occludin, N-cadherin, vimentin and claudin-1 in the testes of B[a]P treated group by immunofluorescence detection. B[a]P induced BTB component protein decreased were also found in TM4 cells exposed to 5μmol/L B[a]P for 24h. We found a significantly decrease of testosterone level and a significantly increase of estrogen level in the serum of treated groups comparing with the control one by radioimmunoassay. TM4 cells, MLTC-1 cells and GC-2 cells was cultured with medium contains B[a]P. MTT Cell Proliferation and Cytotoxicity Assay, cell apoptosis analysis, FACScan analyzer, We observed apparent increase of TM4 and GC-2 cells apoptosis after expose to B[a]P for 24h. B[a]P induced TM4 cell, GC-2 cell and MLTC-1 cell G2/M phase cell arrest. In conclusion, these results suggested that BaP has an adverse impact on male reproduction, it can cross the blood-testis barrier and damage it, the component proteins of the BTB significantly decreased, it can also produce adverse impact on male germ cells.

This research has done to investigate the effect of 2-Methoxyethanol on the testicular histology of the male mice and also the influence the length of time after administration 2-ME stopped in the recovery of the spermatogenic cells and the diameter also the thicknes of seminiferous tubule. Thirty BALB/C male mice 8–9 week old, weighed 28–30 grams body weight. Those mice separated to 6 groups with 5 male mice each group. Those mice were treated with 2-ME 200 mg/kg body weight daily by intra peritoneal injection, within 3 weeks (K1). To investigate the influence the length of time after administration 2-ME stopped, the male mice after treated by 2-ME in 3 weeks also given by the length of time after 2-ME administration stopped 1, 2, 3 and 4 weeks (P1, P2, P3 and P4). The control animal given by intraperitoneal administration of saline. Histological observation was performed on the number of spermatogonium, primary spermatocyte, oval spermatid and the diameter also epithelial thickness of seminiferous tubules. The data were analyzed by One-Sample T-test to investigate the differences between K0 and K1. One Way ANOVA to investigate the influence the length of time after 2-ME administration stopped in the P1, P2, P3 and P4 and then continuing by LSD (Least Significant Difference) to show the differences groups of treatment. The result showed that administration 2-ME could destroy the seminiferous tubules in the testes. Its presented by the decreasing of the number spermatogonium, primary spermatocyte, oval spermatid and diameter also epithelial thickness of seminiferous tubule. The length of time after administration 2-ME stopped could recover seminiferous tubules condition. Its presented by the increasing of the number spermatogonium, primary spermatocyte, oval spermatid, and diameter also epithelial tickness of seminiferous tubules. The conclution of this research were, 2-ME could destroy the testicular histology of the male mice and the length of time after administration 2-ME stopped have linear correlation with seminiferous tubules recovery.
