However, some animal species may show symptoms of poisoning after eating onions. Among animal species, cats and dogs are relatively susceptible to onion-induced oxidative damage, followed by cattle, horses, sheep, goats, rats, and mice, in order of increasing resistance (<a href=\"#j_jvetres-2017-0068_ref_008\" rid=\"j_jvetres-2017-0068_ref_008\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">8<\/a>, <a href=\"#j_jvetres-2017-0068_ref_021\" rid=\"j_jvetres-2017-0068_ref_021\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">21<\/a>).<\/p>\n<p>The toxic elements in onions are mainly n-propyl disulfide (<a href=\"#j_jvetres-2017-0068_ref_005\" rid=\"j_jvetres-2017-0068_ref_005\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">5<\/a>, <a href=\"#j_jvetres-2017-0068_ref_022\" rid=\"j_jvetres-2017-0068_ref_022\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">22<\/a>) and sodium n-propyl thiosulfate (<a href=\"#j_jvetres-2017-0068_ref_018\" rid=\"j_jvetres-2017-0068_ref_018\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">18<\/a>, <a href=\"#j_jvetres-2017-0068_ref_025\" rid=\"j_jvetres-2017-0068_ref_025\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">25<\/a>), which can increase the counts of Heinz bodies and decrease glutathione concentration in erythrocytes. The mechanism that causes onion poisoning in dogs is attributed to damage of the antioxidant system in erythrocytes, causing series of pathological changes in erythrocyte membrane and intracellular materials, and finally leading to haemolytic anaemia (<a href=\"#j_jvetres-2017-0068_ref_024\" rid=\"j_jvetres-2017-0068_ref_024\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">24<\/a>). Clinical symptoms mainly include red urine, a decrease in red blood cells, as well as a substantial increase in Heinz bodies and reticulocyte number. It should be noted that if the severely poisoned dogs are not treated appropriately, they will die eventually. It is reported that raw onions, cooked onions, dehydrated onions, and crushed onions are all potentially toxic for dogs (<a href=\"#j_jvetres-2017-0068_ref_007\" rid=\"j_jvetres-2017-0068_ref_007\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">7<\/a>).<\/p>\n<p>Hydrogen is the most abundant element in the universe. Until recently the knowledge on potential biological application of hydrogen was scarce. In 2007, Ohsawa <em>et al<\/em>. (<a href=\"#j_jvetres-2017-0068_ref_020\" rid=\"j_jvetres-2017-0068_ref_020\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">20<\/a>) reported that 2% inhalation of hydrogen gas could ameliorate significantly the cerebral ischaemia reperfusion injury in rats, and it was based on a selective decrease in hydroxyl free radical (\u2022OH) and peroxynitrite (ONOO\u2013), which were much more reactive than other reactive oxygen species (ROS) (<a href=\"#j_jvetres-2017-0068_ref_020\" rid=\"j_jvetres-2017-0068_ref_020\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">20<\/a>). The study caused quickly a widespread concern and scientists had made great progress in medical application of hydrogen molecule. Many published papers have indicated that hydrogen has numerous biological effects, such as selective antioxidation (<a href=\"#j_jvetres-2017-0068_ref_020\" rid=\"j_jvetres-2017-0068_ref_020\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">20<\/a>), anti-infection (<a href=\"#j_jvetres-2017-0068_ref_010\" rid=\"j_jvetres-2017-0068_ref_010\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">10<\/a>), anti-tumour (<a href=\"#j_jvetres-2017-0068_ref_017\" rid=\"j_jvetres-2017-0068_ref_017\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">17<\/a>), and anti-radiation (<a href=\"#j_jvetres-2017-0068_ref_014\" rid=\"j_jvetres-2017-0068_ref_014\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">14<\/a>), and it does not exert any cytotoxicity even at high concentration (<a href=\"#j_jvetres-2017-0068_ref_001\" rid=\"j_jvetres-2017-0068_ref_001\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">1<\/a>, <a href=\"#j_jvetres-2017-0068_ref_013\" rid=\"j_jvetres-2017-0068_ref_013\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">13<\/a>). Compared with other known antioxidants, hydrogen has many distinct advantages, such as selective oxidation, non-toxicity, high permeability, no residues, relative safety, and low cost (<a href=\"#j_jvetres-2017-0068_ref_009\" rid=\"j_jvetres-2017-0068_ref_009\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">9<\/a>).<\/p>\n<p class=\"p p-last\">Combining the main mechanism of the dogs&#8217; onion poisoning with biological applications of hydrogen, the purpose of this study was to assess the therapeutic effect of hydrogen on the damages induced by onion poisoning in dogs.<\/p>\n<\/div>\n<div id=\"j_jvetres-2017-0068_s_002\" class=\"tsec sec\">\n<div class=\"goto jig-ncbiinpagenav-goto-container\"><a class=\"tgt_dark page-toc-label jig-ncbiinpagenav-goto-heading\" href=\"#\" title=\"Go to other sections in this page\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">Go to:<\/a><\/div>\n<h2 class=\"head no_bottom_margin ui-helper-clearfix\" id=\"j_jvetres-2017-0068_s_002title\">Material and Methods<\/h2>\n<div id=\"j_jvetres-2017-0068_s_002_s_001\" class=\"sec sec-first\">\n<h3 id=\"j_jvetres-2017-0068_s_002_s_001title\">Model establishment and sample collection<\/h3>\n<p class=\"p p-first-last\">A total of 16 adult beagle dogs were used in this experiment. The dogs were vaccinated, individually housed, and no substances that would affect the results of the experiment were administered during the experiment. All dogs were divided into two equal groups: control group (group C) in which the dogs did not undergo any treatment after poisoning, and hydrogen group (group H<sub>2<\/sub>) in which the dogs were injected with hydrogen after poisoning. All dogs were fed dehydrated onion powder at the dose of 10 g\/kg for three days. Onion powder was mixed with cooked meat when fed. Heinz&#8217;s ratio of more than 50% and haematuria indicated that the poisoning model had been successfully established. Hydrogen was produced by hydrogen generator (Saikesaisi, China) and was stored in a sealed bag, using a syringe to extract hydrogen gas from the exhaust hole when needed. The dogs in group H<sub>2<\/sub> were injected hydrogen subcutaneously in the dose of 0.2 mL\/kg (<a href=\"#j_jvetres-2017-0068_ref_023\" rid=\"j_jvetres-2017-0068_ref_023\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">23<\/a>) for 12 days, in which the Heinz bodies almost disappeared. Blood samples of two groups were collected from the jugular vein one week before feeding the onion powder (day \u20137), one day before injecting hydrogen (day 0), and 2 h after injection of hydrogen gas on days 1, 3, 5, 7, 9, and 12 of experimental treatment.<\/p>\n<\/div>\n<div id=\"j_jvetres-2017-0068_s_002_s_002\" class=\"sec\">\n<h3 id=\"j_jvetres-2017-0068_s_002_s_002title\">Index measurement and method<\/h3>\n<p class=\"p p-first\">Indexes measured included five aspects: clinical symptoms, routine blood indexes, blood smears, liver and kidney function, and antioxidant system of erythrocytes.<\/p>\n<p>In the entire course of the experiment, the clinical symptoms were closely observed, mainly including the following aspects: urine colour, dietary status, body temperature, and status of visible mucosa.<\/p>\n<p>The haematology index was tested timely. Red blood cell (RBC) and white blood cell (WBC) counts, haemoglobin (HGB), and haematocrit (HCT) were determined with a fully automated haematology analyser (MEK-7222K, Japan).<\/p>\n<p>Blood smears were mainly used to detect Heinz bodies and reticulocytes. Fresh blood was stained with Wright Giemsa staining method to count Heinz bodies, which were determined by the percentage of cells that had Heinz bodies within a population of 500 erythrocytes counted (<a href=\"#j_jvetres-2017-0068_ref_007\" rid=\"j_jvetres-2017-0068_ref_007\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">7<\/a>). Reticulocytes were observed after staining with brilliant cresyl blue. The stain and blood were mixed in a 1:1 ratio, incubated for 15 min or longer at room temperature, then blood smears were assessed according to conventional criteria. At least 1,000 RBCs were counted and Miller\u2032s method was used to make reticulocyte counting precise. The reticulocyte cytoplasm contained light or dark blue mesh structure after staining.<\/p>\n<p>The anticoagulated blood was centrifuged at 2,500 g\/min for 10 min, and the plasma was used to determine the concentration of biochemical markers characteristic for hepatic and renal functions, and haemolytic ratio. Blood urea nitrogen (BUN), creatinine (CRE), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBIL), and direct bilirubin (DBIL) were determined.

model of onion poisoning in dogs was successfully established, and typical haemolytic anaemia symptoms were observed in the animals. A previous study (<a href=\"#j_jvetres-2017-0068_ref_011\" rid=\"j_jvetres-2017-0068_ref_011\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">11<\/a>) has revealed that onion poisoning occurs in dogs when the amount of onions fed accounts for more than 0.5% of the animal\u2019s weight. Considering the different moisture content of fresh onions, dehydrated onion powder was used in this study because of ease of administration and better control of the dose (<a href=\"#j_jvetres-2017-0068_ref_007\" rid=\"j_jvetres-2017-0068_ref_007\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">7<\/a>). The final dose of onion powder was based on the results of a preliminary study.<\/p>\n<p>The routine blood indexes, blood smear, biochemical markers of liver and kidney function, and erythrocyte antioxidant system all basically followed the trend of poisoning-recovering. Heinz bodies and MDA increased to peak and then decreased, which was consistent with the results of previous research (<a href=\"#j_jvetres-2017-0068_ref_024\" rid=\"j_jvetres-2017-0068_ref_024\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">24<\/a>). Some physiological indicators suggested that the dogs in group H<sub>2<\/sub> recovered first in relation to group C, <em>e.g<\/em>. Heinz bodies which disappeared first in the group H<sub>2<\/sub>. However, all dogs in two groups returned to healthy physiological state by the end of experiment. The dogs in group C were also self-healing finally due to the effective removal system of RBC, which included two sets of antioxidant systems. One was enzymatic system, such as superoxide dismutase (SOD), and the other was non-enzymatic system including vitamin C, glutathione, vitamin E, <em>etc<\/em>. (<a href=\"#j_jvetres-2017-0068_ref_004\" rid=\"j_jvetres-2017-0068_ref_004\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">4<\/a>, <a href=\"#j_jvetres-2017-0068_ref_016\" rid=\"j_jvetres-2017-0068_ref_016\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">16<\/a>). These specific scavenging systems weaken the toxic effects of hydrogen peroxide and other ROS (<a href=\"#j_jvetres-2017-0068_ref_002\" rid=\"j_jvetres-2017-0068_ref_002\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">2<\/a>), and eventually relieved the symptoms of poisoning in the dogs which recovered in the end.<\/p>\n<p>There was no drastic change in CRE and BUN in comparison to the period before feeding onions. It was because the kidneys had a strong reserve and compensatory capacity, so CRE and BUN were usually at the healthy level in the early detection of renal damage, until substantial impairment of the kidneys was observed or the development of end-stage renal disease occurred. The results indicated that the<\/p>\n<p>poisoned dogs did not show severe kidney damage in the experimental process, which corresponded to the previous study stating that serum BUN or UC ratio and glomerular filtration rates (GFR) did not show an increase in anaemic dogs (<a href=\"#j_jvetres-2017-0068_ref_015\" rid=\"j_jvetres-2017-0068_ref_015\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">15<\/a>).<\/p>\n<p>Hydrogen influenced the selective oxidation and could react with the active oxygen, such as \u2022OH and ONOO-, that had very strong oxidation directly (<a href=\"#j_jvetres-2017-0068_ref_020\" rid=\"j_jvetres-2017-0068_ref_020\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">20<\/a>). The results obtained demonstrated that the levels of hydroxy radical inhibition activity in group H<sub>2<\/sub> were significantly higher than in group C from the third day of hydrogen injection, and dogs of the group H<sub>2<\/sub> recovered first. T-AOC, GSH, CAT, and MDA in group H<sub>2<\/sub> showed significant differences on some days after hydrogen injection, suggesting that the hydrogen could improve the antioxidant levels of the body and lower the levels of oxidative products, which was also shown in previous studies (<a href=\"#j_jvetres-2017-0068_ref_003\" rid=\"j_jvetres-2017-0068_ref_003\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">3<\/a>, <a href=\"#j_jvetres-2017-0068_ref_027\" rid=\"j_jvetres-2017-0068_ref_027\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">27<\/a>). This was not proven to be the direct effect of hydrogen, but it might be related to the mutual relation between the oxidation system, as high level of intracellular GSH could cause reduction reaction with H<sub>2<\/sub>O<sub>2<\/sub>, which had a direct correlation with CAT.<\/p>\n<p>The counts of reticulocytes in group H<sub>2<\/sub> were significantly higher than in group C, indicating that hydrogen could improve bone marrow haematopoietic capacity (<a href=\"#j_jvetres-2017-0068_ref_012\" rid=\"j_jvetres-2017-0068_ref_012\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">12<\/a>), and the trend was consistent with the changes of RBC. MDA was one of the lipid peroxidation products. Hydrogen peroxide and MDA could oxidise the sulfhydryl groups of haemoglobin, causing the denaturation of haemoglobin and the formation of Heinz bodies (<a href=\"#j_jvetres-2017-0068_ref_019\" rid=\"j_jvetres-2017-0068_ref_019\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">19<\/a>, <a href=\"#j_jvetres-2017-0068_ref_024\" rid=\"j_jvetres-2017-0068_ref_024\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">24<\/a>). The number of Heinz bodies between the two groups was in conformity with MDA change.<\/p>\n<p>The lipid peroxidation also decreased the fluidity and deformation of erythrocyte membrane (<a href=\"#j_jvetres-2017-0068_ref_024\" rid=\"j_jvetres-2017-0068_ref_024\" class=\" bibr popnode\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">24<\/a>), resulting in more serious damage of erythrocytes, which would cause haemoglobinaemia and haemoglobinuria. The values of the haemolytic rate, which had positive correlation with the injury degree of erythrocyte membrane, were lower in group H<sub>2<\/sub> than in group C on some days, showing that hydrogen could inhibit the lipid peroxidation at a certain extent, reduce the oxidative damage of erythrocyte membrane, leading to reduction of the haemolysis degree in the poisoned dogs. The significant differences in the blood indexes observed in the present study between the two groups indicate that hydrogen could reduce the oxidative damage of the erythrocytes, and then lead to reduction in the degree of haemolytic anaemia.<\/p>\n<p class=\"p p-last\">In conclusion, the results indicate that continuous injection of hydrogen in onion poisoned dogs would relieve haemolytic anaemia and increase bone marrow haematopoietic ability. Hydrogen could also reduce the oxidative damage of erythrocyte membrane by reducing oxidation products and increasing antioxidant substances, thus causing reduction of the number of Heinz bodies and haemolysis rate. Hydrogen could be considered as an auxiliary treatment drug for onion poisoned dogs in the future.<\/p>\n<\/div>\n<div id=\"fn-group-a.i.a\" class=\"tsec sec\">\n<div class=\"goto jig-ncbiinpagenav-goto-container\"><a class=\"tgt_dark page-toc-label jig-ncbiinpagenav-goto-heading\" href=\"#\" title=\"Go to other sections in this page\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">Go to:<\/a><\/div>\n<h2 class=\"head no_bottom_margin ui-helper-clearfix\" id=\"fn-group-a.i.atitle\">Footnotes<\/h2>\n<p><!--back\/fn-group--><\/p>\n<div class=\"fm-sec half_rhythm small\">\n<p class=\"fn sec\" id=\"j_jvetres-2017-0068_fn_001\">\n<p class=\"p p-first-last\"><strong>Conflict of Interests Statement<\/strong>: The authors declare that there is no conflict of interests regarding the publication of this article.<\/p>\n<\/p>\n<p class=\"fn sec\" id=\"j_jvetres-2017-0068_fn_002\">\n<p class=\"p p-first-last\"><strong>Financial Disclosure Statement<\/strong>: This study was funded by the National Natural Science Foundation of China, China Postdoctoral Science Foundation, and Young Talents Project of Northeast Agricultural University.<\/p>\n<\/p>\n<p class=\"fn sec\" id=\"j_jvetres-2017-0068_fn_003\">\n<p class=\"p p-first-last\"><strong>Animal Rights Statement<\/strong>: All animal procedures were approved by the Laboratory Animal Care and Use Committee of Northeast Agricultural University.<\/p>\n<\/p>\n<\/div>\n<\/div>\n<div id=\"ref-list-a.i.b\" class=\"tsec sec\">\n<div class=\"goto jig-ncbiinpagenav-goto-container\"><a class=\"tgt_dark page-toc-label jig-ncbiinpagenav-goto-heading\" href=\"#\" title=\"Go to other sections in this page\" role=\"button\" aria-expanded=\"false\" aria-haspopup=\"true\">Go to:<\/a><\/div>\n<h2 class=\"head no_bottom_margin ui-helper-clearfix\" id=\"ref-list-a.i.btitle\">References<\/h2>\n<div class=\"ref-list-sec sec\" id=\"reference-list\">\n<div class=\"ref-cit-blk half_rhythm\" id=\"j_jvetres-2017-0068_ref_001\">1. <span class=\"element-citation\">Abraini J.H., Gardette-Chauffour M.C., Martinez E., Rostain J.C., Lemaire C..
