Abstract
Environmental hazards are an increasing concern due to the rapid pace of industrialization. Among these hazards, noise and carbon monoxide (CO) are common risk factors and have been shown to cause serious health problems. However, existing studies focused on the individual effects of noise and CO exposure and the combined effects of these two factors remain poorly understood. Our study aimed to examine the combined effects of noise and CO exposure on testicular function by constructing individual and combined exposure models. Our findings indicated that combined exposure to noise and CO was associated with a higher risk of testicular damage and male reproductive damage when compared to exposure alone. This was evidenced by poorer semen quality and more severe pathological damage to the testis. This combined exposure led to higher levels of oxidative stress and apoptosis in the testes, with bioinformatics analyses suggesting the signaling pathways involved in these responses. Specifically, activation of the P53 signaling pathway was found to contribute to the testicular damage caused by the combined exposure. Encouragingly, pterostilbene (PTE), a novel phytochemical, alleviated combined exposure-induced testicular damage by reducing oxidative stress and germ cell apoptosis. Overall, we identified joint reproductive toxicity resulting from the exposure to noise and CO, and found that PTE is a promising potential treatment for injuries caused by these factors. The cover image is based on the Research Article Effects and possible mechanisms of combined exposure to noise and carbon monoxide on male reproductive system in rats by Yingqing Li et al., https://doi.org/10.1002/tox.23927.

IRANIAN RED CRESCENT MEDICAL JOURNAL 2016; 18:e27061. [PMID: 27437130 PMCID: PMC4939414 DOI: 10.5812/ircmj.27061] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 01/17/2015] [Revised: 08/18/2015] [Accepted: 09/16/2015] [Indexed: 12/13/2022]
Abstract
Background Intoxication due to carbon monoxide (CO) is one of the most common types of poisoning. Cardiac effects of carboxyhemoglobin (COHb) range from simple arrhythmias to myocardial infarction. Objectives The current study aimed to investigate the relationship between blood carboxyhemoglobin and high-sensitivity cardiac troponin T (hs-cTnT) level with a highly sensitive assay in patients with acute carbon monoxide poisoning. Patients and Methods This retrospective study was conducted on 141 (54 males and 87 females) patients, with acute CO intoxication, admitted to the Sevket Yilmaz research and education hospital emergency unit during a one-year period (January 2012 - January 2013). The patients were divided into three groups based on COHb levels: Group I, mild COHb level < 15%; Group II, COHb between 15% and 25%; Group III, severe acute CO intoxication COHb levels > 25%. COHb, hs-cTnT (Stat), creatine kinase (CK) and creatine kinase-myocardial band (CK-MB) levels were measured on admission. Results The mean age of the patients was 38 ± 16 years. COHb levels ranged from 8 to 35. hs-cTnT levels on inclusion in this study were slightly different between the groups (P = 0.05). COHb levels with hs-cTnT values were weakly correlated (r = 0.173, P = 0.041); on the other hand, CK-MB levels were not correlated with COHb (r = 0.013, P = 0.883). Conclusions In patients without clear signs of myocardial infarction, even mild CO poisoning was associated with quantifiable circulating levels of hs-cTnT when TnT was measured using a highly sensitive assay in the current study patients. Plasma levels of the hs-TnT and CK-MB assays were not correlated with the COHb levels in the current study patients.

Abstract
We hypothesized that different types of residential heating would be associated with different levels of indoor carbon monoxide (CO) and further that this might result in a differential in the concentration of cyclic 3':5' guanosine monophosphate (cGMP) in blood platelets in exposed residents. Individuals, who were recruited from homes using different fuel for heating, donated a venous blood sample in the winter and in the summer. In the winter the median blood platelet cGMP value for the group using liquid propane gas (LPG) was 65% higher than for the group using piped natural gas for heating (p <0.001). Also in the group using LPG, the median concentration of cGMP in the winter was 39% higher than the summer median (p < 0.003). The mean indoor concentrations of CO were measured over a period of 1 week during the winter and were <1 ppm. We conclude that observed differences were associated with emissions from different types of heating but that CO exposure alone is too low to explain these.

[PMID: 16808911 DOI: 10.1016/j.envres.2006.05.010] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/31/2006] [Revised: 05/10/2006] [Accepted: 05/17/2006] [Indexed: 05/10/2023]
Abstract
Cerebral cholinergic muscarinic receptors (MR) have been suggested as one of the sensitive biochemical endpoints of the central nervous system altered by developmental exposure to the widespread seafood contaminant methylmercury (MeHg). In adult rats, MeHg has been shown to alter MR binding both in the brain and lymphocytes, supporting the use of MR in blood cells as a surrogate marker of CNS changes. The effects of MeHg have been evaluated on rat lymphocyte MR binding (using [3H]QNB as specific muscarinic ligand) in vivo (after perinatal exposure) and in vitro. For comparison, in vitro studies were also performed on human lymphocytes. Exposure to 1 mg MeHg/kg/day during pregnancy and lactation (from GD7 to PND7) significantly enhanced lymphocyte MR density in both adult and young rats 21 days after delivery, with a more pronounced effect in the mothers (B(max) increase of 139%) than in the male offspring (+49%) and female offspring (+73%) as compared with their respective controls (33+/-4, 41+/-8, and 37+/-4 fmol/million cells), in accordance with the higher Hg levels detected in the adult blood (11.3+/-2.2 microg/mL) than in pups (1.3+/-0.4 microg/L in both genders). A lower MeHg dose (0.5 mg/kg/day) was without any effect on lymphocyte MRs. In in vitro studies, MeHg was an almost equipotent inhibitor of (3)H-QNB binding to rat and human lymphocyte MRs (IC50 values were 4.1+/-0.29, 5.2+/-0.51, and 5.0+/-0.9 microM for total rat lymphocytes, rat T lymphocytes, and total human lymphocytes, respectively). Notably, the IC50 values for MeHg to lymphocyte MRs were comparable to the Hg levels reached in blood (5-50 microM) of the PND21 rats exposed to MeHg. The finding that the MR binding is a target for the effects of MeHg in peripheral blood cells is in accordance with our previous data in brain [Coccini et al., 2006. Effects of developmental co-exposure to methylmercury and 2,2',4,4',5,5'-hexachlorobiphenyl (PCB153) on cholinergic muscarinic receptors in rat brain. Neurotoxicology, in press], and supports the use of this peripheral endpoint as a biomarker of MeHg-induced cerebral muscarinic alterations. The similarity of MeHg IC50 binding data between human and rat in peripheral tissues suggests the possible application of such biomarker to humans exposed to environmental chemicals.
