{"title":"Vitamin C pretreatment protects from nickel-induced acute nephrotoxicity in mice","authors":"Imededdine Kadi, F. Dahdouh","doi":"10.1515/aiht-2016-67-2753","DOIUrl":"https://doi.org/10.1515/aiht-2016-67-2753","url":null,"abstract":"Abstract Nickel is an abundant carcinogenic and nephrotoxic metal whose activity leads to renal impairment. Previous studies have shown a protective effect of simultaneous vitamin C administration on acute and chronic nickel toxicity. However, very little research relating to the effect of vitamin C pretreatment in preventing nickel-induced acute nephrotoxicity is available. Therefore, the present study aimed to determine the efficiency of vitamin C (VC) pretreatment in preventing acute renal toxicity of nickel. Mice were pretreated orally with vitamin C (16.6 mg kg-1 body weight, b.w.) for seven consecutive days, prior to intraperitoneal (i.p.) administration of nickel chloride at different doses (3, 5, and 10 mg Ni kg-1 b.w.) for an exposure period of 24 hours. Thereafter, animals were killed and kidney tissue and blood samples were taken for histological examination and biochemical marker analyses. Vitamin C pretreatment alone did not alter the levels of serum kidney markers (creatinine, urea, and uric acid). However, treatment with Ni alone showed a significant increase in the levels of serum creatinine, urea, and uric acid with marked necrotic epithelial cells and infiltration by inflammatory cells in kidney sections as compared to the control group. Pretreatment with vitamin C and treatment with Ni at all doses tested for 24 hours showed a significant decrease in the levels of serum creatinine, urea, and uric acid, as well as an improvement in histological changes compared to those previously seen in the group treated with Ni alone. It is concluded that vitamin C pretreatment effectively improved renal function and tissue damage caused by nickel.","PeriodicalId":8292,"journal":{"name":"Archives of Industrial Hygiene and Toxicology","volume":"6 1","pages":"210 - 215"},"PeriodicalIF":0.0,"publicationDate":"2016-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90207773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the first study we evaluated all fish species of both sexes obtained from the river Ljubljanica from its source to mouth. In the second study we focused on the rainbow trout (Oncorhynchus mykiss) and brown trout (Salmo trutta m. fario) males from 30 rivers and streams in different parts of Slovenia. The male gonads were histologically assessed for the presence of oocytes to determine the frequency and degree of intersex. Oocytes were found in the testicular tissue of a single grayling (Thymallus thymallus) and in the adipose tissue adjacent to the testis of a single common barbel (Barbus barbus), both from the Ljubljanica. Several cyst-like structures that resemble degenerated presumptive oocytes were also present in several trout testes. This preliminary report is the first of its kind in Slovenia. To gain a better insight into the intersex issue in Slovenia, we plan to regularly biomonitor freshwater pollution by histologically examining fish gonads and, if possible, by determining vitellogenin plasma levels in fish.","PeriodicalId":8292,"journal":{"name":"Archives of Industrial Hygiene and Toxicology","volume":"40 1","pages":"216 - 222"},"PeriodicalIF":0.0,"publicationDate":"2016-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73846690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Heavy metals can accumulate in these foundations for decades, as it is a common beekeeping practice to recycle wax. Beeswax samples were analysed using GFAAS for As, Cd, Pb, and Hg concentrations during the production of beeswax foundations using casting technology with a prolonged cooling and sedimentation phase. Significant differences were determined in the concentrations of As, Cd, Pb (p<0.01, all), and Hg (p<0.05) between the three levels of wax in a double-walled steel casting container and comb foundations (CF) during the processing stage. Concentrations (mg kg-1) of the examined metals in comb foundations as the final product ranged as follows: As 0.01-0.88; Cd 1.26-3.55; Pb 82.5-171, and Hg 0.29-1.46. All examined element concentrations demonstrated similar distribution and ratio in different layers, ranging from the lowest concentrations in layers from which wax material is used for comb foundations as the final product, to the highest concentrations in sedimented layer, which represents waste. The obtained results suggest that the described method could effectively eliminate a significant amount of heavy metals from the initial material used for the production of new beeswax foundations.","PeriodicalId":8292,"journal":{"name":"Archives of Industrial Hygiene and Toxicology","volume":"39 1","pages":"223 - 228"},"PeriodicalIF":0.0,"publicationDate":"2016-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78366949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Because it produces a biomass rich in extracted toxic metals, further treatment of this biomass is necessary. The aim of our study was to assess the five-year potential of the following native wild plants to produce biomass and remove heavy metals from a polluted site: poplar (Populus ssp.), ailanthus (Ailanthus glandulosa L.), false acacia (Robinia pseudoacacia L.), ragweed (Artemisia artemisiifolia L.), and mullein (Verbascum thapsus L). Average soil contamination with Pb, Cd, Zn, Cu, Ni, Cr, and As in the root zone was 22,948.6 mg kg-1, 865.4 mg kg-1, 85,301.7 mg kg-1, 3,193.3 mg kg-1, 50.7 mg kg-1, 41.7 mg kg-1,and 617.9 mg kg-1, respectively. We measured moisture and ash content, concentrations of Pb, Cd, Zn, Cu, Ni, Cr, and As in the above-ground parts of the plants and in ash produced by combustion of the plants, plus gross calorific values. The plants’ phytoextraction and phytostabilisation potential was evaluated based on their bioconcentration factor (BCF) and translocation factor (TF). Mullein was identified as a hyperaccumulator for Cd. It also showed a higher gross calorific value (19,735 kJ kg-1) than ragweed (16,469 kJ kg-1).The results of this study suggest that mullein has a great potential for phytoextraction and for biomass generation, and that ragweed could be an effective tool of phytostabilisation.","PeriodicalId":8292,"journal":{"name":"Archives of Industrial Hygiene and Toxicology","volume":"466 1","pages":"229 - 239"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76829571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This retrospective, ecological study included 20,228 patients with a cardiovascular disease as their primary diagnosis who were examined in the EDs of two Croatian University Hospitals, Sisters of Charity and Holy Spirit, in the study period July 2008-June 2010. The median of daily CVD-related ED visits during the study period was 28 and was the highest during winter. A significant negative correlation was found between CVD-related emergency visits and air temperature measured no more than three days prior to the visit, and the highest negative correlation coefficient was measured two days earlier (R=0.266, p≤0.001). The number of CVD-related emergency visits significantly correlated with the average NO2 concentration on the same day (R=0.191, p<0.001). The results of multiple stepwise regression analysis showed that the number of CVD-related emergency visits depended on air temperature, and NO2 and O3 concentrations. The higher the air temperatures, the lower the number of daily CVD-related emergency visits (p<0.001). An increase in NO2 concentrations (p=0.005) and a decrease in O3 concentrations of two days earlier (p=0.006) led to an increase in CVD-related ED visits. In conclusion, the decrease in O3 concentrations and the increase in NO2, even if below the legally binding thresholds, could be associated with an increase in CVD-related emergency visits and a similar effect was observed with lower temperature measured no more than three days prior to the visit.","PeriodicalId":8292,"journal":{"name":"Archives of Industrial Hygiene and Toxicology","volume":"1638 1","pages":"240 - 246"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77724596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Virtually nothing is known about its effect in humans. Therefore, the aim of this study was to explore the association between occupational noise exposure and serum testosterone in a representative sample of the general population. The sample has been taken from the National Health and Nutrition Examination Survey (NHANES) data for the period between 1999 and 2004 and is limited to employed men aged 16-85+ years at the time. The associations between noise exposure (either established according to the Occupational Information Network - O*NET categories or self-reported) and total and free testosterone (TT and FT, respectively) were analysed using linear regression models with increasing adjustments. In the fully adjusted model (n=414), the third quartile of the O*NET noise exposure was associated with lower TT and FT, which reached statistically significant decrease of -58.32 ng dL-1 (95 % CI: -111.22, -5.42) and -1.58 ng dL-1 (95 % CI: -2.98, -0.18), respectively. In stratified analyses, younger, lower income, normal weight, better hearing, and workers not using hearing protection at work experienced significantly more severe adverse effects than the rest. The odds for hypogonadism (TT<300 ng dL-1) did not significantly rise with one interquartile range increment in O*NET noise exposure (OR=1.24, 95 % CI: 0.64, 2.39). Self-reported loud noise exposure did not significantly decrease TT when all men were considered (n=214) and only in the men ≥37 years did it decrease TT significantly by -87.55 ng dL-1 (95 % CI: -158.35, -16.74). In conclusion, noise exposure was associated with lower TT and FT only in some population subgroups and these associations were non-linear.","PeriodicalId":8292,"journal":{"name":"Archives of Industrial Hygiene and Toxicology","volume":"70 1","pages":"247 - 258"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80941636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The patient had several short-lived clonic seizures before admission. On arrival, she had an episode of tonic-clonic seizure, lasting for three minutes, which lead to cardiopulmonary arrest after administration of 10 mg diazepam intravenously. Endotracheal intubation and cardiopulmonary resuscitation were attempted. After 30 min, normal sinus rhythm with a palpable pulse was noted, and the patient was put on mechanical ventilation and transferred to the intensive care unit (ICU). Her vital signs were stable with vasopressor medication support (norepinephrine infusion at 10 μg min-1). She had repeated short-lived tonic-clonic seizure-like movements, which responded well to midazolam. Her past medical and family history was negative for seizure, heart diseases, and hereditary disorders. Repeated neurological examination indicated that the patient had no motor response to pain and had fixed dilated pupils without corneal and vestibuloocular reflexes. About 48 h after admission to the ICU, she experienced asystole, which did not respond to resuscitation. Tramadol HCl is a synthetic opioid drug that blocks reuptake of monoamine and inhibits NMDA glutamatergic activity, while it has low affinity for mu-opioid receptors (1). It has a low potential for abuse and is usually prescribed for control of moderate to severe pain (2). Tramadol is mainly metabolised by the hepatic cytochrome P450 2D6 (CYP2D6), and its active metabolites are responsible for complications, meaning that in a CYP2D6 rapid metaboliser patient excessive side effects may develop within a short time following its overdose (2, 3). It has been reported that the LD50 value for Tramadol is about 300-350 mg kg-1 body weight in animal models (4). However, reviewing the literature, we found that it is generally considered to be non–life threatening in humans, hence, co-ingestion of Tramadol and other agents such as analgesics, muscle relaxants, and CNS depressants is occasionally reported from toxicological samples of postmortem human specimens (2, 5). In fact, there are only a few case reports of human fatality due to Tramadol overdose alone (2). It has been suggested that CYP2D6 ultra-rapid metaboliser patients may develop fatal complications (5). As its overstated toxic manifestations and accordingly its fatality are prospected during the first hours, which is related to its metabolism (5), this time is crucial in patient's care. Moreover, in the emergency situation, we have no idea about the activity of the cytochrome P450 2D6 in patients with Tramadol overdose, which can be induced by other drugs. Therefore, as cardiopulmonary arrest can be a fatal complication (5), we strongly suggest that all patients with exaggerated signs or symptoms of toxicity who consumed more than 150 mg kg-1 (the half dose of LD50 values in animal models) of Tramadol (4), should be intubated prophylactic","PeriodicalId":8292,"journal":{"name":"Archives of Industrial Hygiene and Toxicology","volume":"57 8 1","pages":"259 - 259"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78092887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
