Administration / exposure
- Route of administration:
- oral: feed
- Vehicle:
- other: Control diet
- Details on exposure:
- The animals were fed ad libitum the control diet with and without sodium vanadate (100ppm) for one week. The control diet was bought from Oriental Co., Japan and it had the following composition based on 100g of diet: Protein 24.6g, Fat 5.6g, Carbohydrate 52.8g, Cellulose 3.1g, Calcium 1.15g, Phosphorus 0.88g, Magnesium 0.25g, Sodium 0.26g, Potassium 0.89g, Iron 12.3mg, Vitamin B1 2.04mg, Vitamin B2 1.21mg, Vitamin B6 0.92mg, Niacin 9.68mg, Pantothenic acid 3.05mg, Folic acid 0.15mg, Choline 0.23g, Inositol 433mg, Vitamin A 1810 IU, Vitamin D3 80 IU, Vitamin E 10.4mg.
The vanadium content of the control diet was 0.32ppm. - Duration and frequency of treatment / exposure:
- The duration of exposure was one week and this was done via the diet at libitum.

- PHARMACOKINETIC STUDY (Absorption, distribution, excretion)
- Tissues and body fluids sampled (delete / add / specify): urine, faeces, liver, kidney, heart, lung, brain, thymus, spleen, muscle, intestine, stomach, femur and tibia
- Time and frequency of sampling: urine and faeces was collected daily during feeding. The other tissues / organ was collected at the end of the study.
Determination of vanadium in tissues was conducted using an atomic absorption spectrophotometer with a graphic furnace atomizer and in feces and urine directly by flameless atomich absorption spetrophotometry. - Statistics:
- Values were reported as means SEM and the data were analysed using one-way ANOVA or by a Student-Newman-Keul test.
Results and discussion
Main ADME resultsopen allclose all

- Type:
- distribution
- Results:
- The majority of the vanadium distribution was found in the femur, tibia, kidney, spleen and intestine of the experimental group. The tibia had levels of 1.84 µg/g. In the control group the highest vanadium levels were found in the lung (0.13 µg/g).
- Type:
- excretion
- Results:
- The percentages excreted in the urine and feces were 0.86% and 83.5% of the intake (7060 µg/kg/d) respectively.
- Type:
- other: Retention
- Results:
- The retention was 15.7 %
Toxicokinetic / pharmacokinetic studies
- Details on absorption:
- Absorption was calculated to be about 16.5%.
- Details on distribution in tissues:
- The highest vanadium distribution was found in the tibia (1.84 µg/g), and the lowest was found in the brain (0.13 µg/g). In the control group the highest vanadium levels were found in the lung.
- Details on excretion:
- The percentages excreted in the urine and faeces were 0.86% and 83.5% of the intake (7060 µg/kg/d, as vanadium) respectively.
Metabolite characterisation studies
- Metabolites identified:
- no
Any other information on results incl. tables
The recovery of added vanadium in various tissues were from 96.7 to 109.3% with a maximum coefficient of variation of 8.6%.
Applicant's summary and conclusion
- Conclusions:
- The absorption of vanadium was calculated to be 1168 ± 519 µg/kg/d (16.5%) of the total daily intake of 7060 ± 574 µg/kg/d. The results also indicate that the majority of the vanadium was distributed in the femur, tibia, kidney, spleen and intestine for the experimental group. The tibia had levels of 1.84 µg/g. In the control group the highest vanadium levels were found in the lung (0.13 µg/g). Excretion levels / percentages in the urine and faeces were 0.86% and 83.5% of the intake (7060 µg/kg/d) respectively and the retention was 15.7 % of total intake.
