Abstract
Thiabendazole (TBZ) is a benzimidazole; owing to its potent antimicrobial properties, TBZ is extensively employed in agriculture as a fungicide and pesticide. However, TBZ poses environmental risks, and excessive exposure to TBZ through various leakage pathways can cause adverse effects in humans. Therefore, a method must be developed for early and sensitive detection of TBZ over a range of concentrations, considering both human and environmental perspectives. In this study, we used silver nanopillar structures (SNPis) and Au@Ag bimetallic nanoparticles (BNPs) to fabricate a BNP@SNPi substrate. This substrate exhibited a broad reaction surface with significantly enhanced surface-enhanced Raman scattering hotspots, demonstrating excellent Raman performance, along with high reproducibility, sensitivity, and selectivity for TBZ detection. Ultimately, the BNP@SNPi substrate successfully detected TBZ across a wide concentration range in samples of tap water, drinking water, juice, and human serum, with respective limits of detection of 146.5, 245.5, 195.6, and 219.4 pM. This study highlights BNP@SNPi as a promising sensor platform for TBZ detection in diverse environments and contributes to environmental monitoring and bioanalytical studies.

Several dose study of both imazalil and thiabendazole. Birth Defects Res 2020; 112:141-161. [PMID: 31680484 DOI: 10.1002/bdr2.1613] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 10/08/2019] [Accepted: 10/17/2019] [Indexed: 11/08/2022]
Abstract
BACKGROUND Few published studies are reported for neurobehavioral toxicity of combined exposure to fungicides in mammals. This study was aimed to evaluate reproductive and neurobehavioral effects of maternal exposure to combined fungicides in mice. METHODS Imazalil (IMZ) and thiabendazole (TBZ) were given in the diet to provide levels of 0/0% (control), 0.0015/0.006% (IMZ/TBZ), 0.006/0.018%, and 0.024/0.054% during the gestation and lactation periods. Selected reproductive and neurobehavioral parameters were measured in the F1 generation. RESULTS No adverse effect of IMZ/TBZ was observed in litter size, litter weight, or sex ratio at birth. The average body weight of male and female offspring was increased significantly in treatment groups during the lactation period. With respect to behavioral developmental parameters, the swimming head angle on PND 7 of male offspring was significantly accelerated in the treatment groups. After weaning, the movement time of exploratory behavior shortened in a significant dose-related manner in adult males of the F1 generation. In adult females, the rearing time of exploratory behavior lengthened in a significant dose-related manner in the F1 generation. Spontaneous behavior examination indicated that longitudinal patterns of each of the total distance and number of rearing were different during the control and treatment groups in the F1 -generation females. Parallel width of the control and treatment groups was significantly different in the average time of movement and rearing in the F1 -generation females. CONCLUSIONS The high-dose level of IMZ/TBZ in the present study produced several adverse effects in neurobehavioral parameters after weaning without concurrent chemical administration in mice.

Abstract
Thiabendazole was given in the diet to provide levels of 0 (control), 0.031, 0.125, and 0.5% from 5 weeks of age of the F0 generation to 9 weeks of age of the F1 generation in mice, and selected reproductive and neurobehavioural parameters were measured. The average litter size and weight were significantly reduced in the high-dose group at birth. No adverse effects were observed in the sex ratio at birth. The average body weight of offspring was significantly increased in the low-dose group during the late lactation period, and was significantly reduced in the high-dose group during the lactation period. In the assessment of neurobehavioural parameters, surface righting at postnatal day (PND) 7 was significantly delayed in a dose-related manner in both sexes. Swimming limb movement at PND 14 and olfactory orientation at PND 14 were significantly depressed in the high-dose group in both sexes. In movement activity at 3 weeks of age in the F1 generation, vertical time and number of defaecations were significantly decreased in the high-dose group in female offspring. Several adverse effects on reproductive and neurobehavioural parameters were produced at the highest dose level of thiabendazole used in the present study (equivalent to 700-1800 mg/kg bw/day). Slight, dose-related delays were also seen in surface-righting ability at the two lower dose levels. The lowest close level (equivalent to 50-180 mg/kg bw/day) is approximately 500 times the current acceptable daily intake (ADI) of 0-0.1 mg/kg bw.

Abstract
Thiabendazole (TBZ) is a potent anthelmintic and fungicide used in the treatment of parasitic infections in humans and domestic animals and post-harvest protection of agricultural commodities. TBZ is not teratogenic or selectively foetotoxic in rats or rabbits, in contrast to several other benzimidazole derivatives. However, when administered orally to pregnant (Jcl:ICR) mice at lethal dosages, malformations were observed in treated fetuses. To assess whether the effects found in this previous study were attributable to maternal toxicity or TBZ the present study was conducted. TBZ doses of 25, 100 or 200 mg/kg/day were selected based on a preliminary range-finding study in which maternotoxicity was evident at doses of 200 mg/kg/day or above. The compound was administered during gestation days 6-15 as a solution in olive oil. Caesarean sections were completed on gestation day 18 and complete fetal examinations conducted. Decreases in maternal weight gain relative to controls were found at doses of 100 mg/kg/day or above, which paralleled decreases in foetal weights in these same dose groups. However, there were no treatment-related external, visceral or skeletal anomalies in any treatment group. Therefore, TBZ was not teratogenic or selectively foetotoxic in mice, with no-observed-effect levels (NOEL) of 25 and greater than 200 mg/kg/day for maternal and fetal weight effects and teratogenicity, respectively. These results indicate that foetal effects noted in previous studies in mice were probably secondary to severe maternal toxicity.

Abstract
In recent years significant progress has been made in understanding the ecology, epidemiology and related morbidity and development of new tools for the control of soil-transmitted helminths. Such knowledge has recognized the impact of helminth infections on the health of infected groups and has created a rational basis for their control. Schoolchildren harbour some of the most intense helminthic infections, which produce adverse effects on health, growth and scholastic performance. However, although great effort has been put into targeting school-age children, women of child-bearing age and pre-school children are two other groups at high risk of morbidity due to intestinal nematode infections. Highly effective and safety-tested, single-dose anthelminthic drugs are now available, permitting periodical deworming of schoolchildren and other high-risk groups at affordable prices. Four anthelminthics against all intestinal nematodes are included in the WHO Essential Drug List (albendazole, levamisole, mebendazole and pyrantel). Recently ivermectin has also been registered for use against Strongyloides stercoralis in humans. Several well-monitored country experiences have shown that chemotherapy-based control of morbidity due to soil-transmitted helminths is possible and highly cost-effective.

Abstract
Cultured hepatocytes from rat, rabbit, calf, pig, and sheep were used to study metabolism and formation of protein-bound residues of thiabendazole ([(14)C]TBZ), a benzimidazole anthelmintic and fungicide. In all investigated species, major pathways corresponded to 5-hydroxylation of TBZ and its further conjugation. However, marked interspecies differences in rates of TBZ disappearance and 5-hydroxy metabolite formation were demonstrated. Rabbit hepatocytes presented the fastest TBZ biotransformation and were the most extensive hydroxylators. By contrast, the lowest capacity of oxidation was observed for the rat. Two unidentified minor metabolites, designated M1 and M2, were particularly produced by sheep hepatocytes. Moreover, the protein-bound residues in these cells, which could be related to cytochrome P450-dependent oxidation, were formed in 4 times greater amounts than in the other animal cells. These findings substantiate hepatocytes as an in vitro model for prediction of hepatic metabolism in vivo.

Abstract
The relationship between chemical structure and toxicity was explored through the compilation of a large reference database consisting of over 600 chemical substances tested for a variety of endpoints resulting in over 2900 no-observed-effect levels (NOELs). Each substance in the database was classified into one of three structural classes using a decision tree approach. The resulting cumulative distributions of NOELs for each of the structural classes differed significantly from one another, supporting the contention that chemical structure defines toxicity. The database was used to derive a threshold of acceptable human exposure for each of the structural classes that could be applied in the absence of specific toxicity data on a substance within one of the three structural classes. The human exposure thresholds provide guidance on the degree of testing and evaluation required for substances that lack toxicity data.

Abstract
The potential reproductive toxicity of the fungicide and anthelmintic thiabendazole (TBZ) was assessed in Sprague-Dawley rats for two generations. Doses of 10, 30 or 90 mg/kg/day were administered by way of the diet beginning at 8 wk of age for the F0 generation and postnatal wk 4 for the F1 generation and continuing until the animals were killed. Concentrations of TBZ in the diet were adjusted weekly, except during the gestation and lactation intervals when concentrations were held constant. There were no TBZ-related deaths or adverse physical signs during the study. TBZ-related effects consisted of decreases in average body weight gains and food consumption in the middle and high dose groups. In both the F0 and F1 generations during the premating and post-cohabitation periods, the effects in the middle-dose group were observed only in males and were generally slight in magnitude (food consumption 3-5% below control, weight gain 7-18% below control), whereas the effects in the high dose group occurred in both sexes and were slight to moderate in magnitude (food consumption 9-13% below control, weight gain 13-46% below control). During gestation of the F0 females there were slight decreases in average weight gain and food consumption (8% and 4-16% below control, respectively); a similar effect on food consumption, but not weight gain, occurred in the F1 generation. There were no effects on F0 or F1 reproductive performance (including indices of mating, fecundity, fertility, length of gestation, litter size, birth weight, and post-implantation survival), nor were any histomorphological changes observed in the reproductive tissues of animals in the high dose group. There was no evidence of developmental toxicity in the TBZ-exposed F1 or F2 generations, except for slight decreases in average pup weights between postnatal days 4 and 21 in the high dose group (5-10% below control). The NOAEL (no-observed-adverse-effect level) for all developmental, growth, survival and reproductive performance parameters assessed in this study was 10 mg/kg/day.
