Cobalt-Induced Toxicity in Rats: Dose and Time-Dependent Effects

Check if the same lab product or an alternative is used in the 5 most similar protocols
Experiments were performed in adult male Sprague Dawley (SD) rats obtained from Charles River (UK). The body weight range at the start of the experiments was 210–280 g. Food and water were provided ad libitum. Their body weight and general aspects of health were monitored daily.
Freshly-made cobalt chloride hexahydrate (CoCl2.6H2O; Sigma-Aldrich, Dorset, UK) solutions dissolved in distilled water (dH2O) and dH2O were sterilised through a 0.22 μm syringe-driven filter (Merck Millipore, Watford, UK).
Two separate in vivo experiments were performed successively. The first experiment was a time-response experiment in which a 7-day cobalt treatment was compared against a 28-day treatment at a fixed cobalt dose. Animals were treated daily with either 1 mL/kg body weight dH2O (controls) or 1 mg/kg body weight (BW) CoCl2 doses injected i.p. (treated groups). The second in vivo experiment was a dose-response experiment. The animals were given 1 mL/kg dH2O i.p. in the case of the control group, or a range of cobalt solutions- 0.1, 0.5, or 1 mg/kg BW i.p. injections for 28 days. Figure 1 depicts the sample size and design information diagrammatically.

Galvanic-Corrosion-Derived (Co,Fe)OOH Catalyst

A (Co,Fe)OOH sample was synthesized via galvanic corrosion and grown directly on an iron foam. Before the synthesis, a piece of the iron foam (2 cm × 3 cm, Alantum Co., Seongnam-City, Korea) was first etched with 1 M HCl for 15 min to remove the surface oxide layer, after which it was washed with acetone, ethanol, and deionized water under ultrasonication for 10 min. Thereafter, the washed iron foam was immersed in 70 mL of an aqueous solution containing 3.0 mM cobalt chloride hexahydrate (CoCl2·6H2O, Sigma-Aldrich Inc., St. Louis, MO, USA) for 4 h with stirring at room temperature (25 °C). After the galvanic corrosion reaction, the (Co,Fe)OOH on the iron foam sample was thoroughly rinsed with ethanol and deionized water, followed by drying overnight in a convection oven at 70 °C. This sample was named (Co,Fe)OOH.

Cobalt chloride hexahydrate (CoCl2·6H2O) (Sigma-Aldrich, MO, USA) or 1% O2 was used to induce hypoxia in AGS cells as per standard methods (Rath et al., 2016 (link); Wu and Yotnda, 2011 ). CTK7A at 100 µM dose (Arif et al., 2010 (link)) either alone or in combination with CoCl2 (200 µM) was used for 24 h treatment. ERK1/2 inhibitor PD98059, p38 MAPK inhibitor SB203580, and JNK inhibitor IISP600125 (all from Calbiochem, CA, USA) were used at 25 µM dose for 1 h prior to CoCl2 and CTK7A treatment. Superoxide dismutase (SOD) and catalase (CAT) (both from Sigma Aldrich) were used at 200 units/ml and 350 units/ml dose, respectively, for 4 h prior to treatment with CoCl2 and CTK7A. 5-(and 6)-chloromethyl-2,7-dichlorodihydrofluorescein diacetate, acetyl ester (CM-H2-DCFDA; Invitrogen, CA, USA) was used to detect intracellular ROS generation.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
