1Institut für Pharmakologie, Pharmazie und Toxikologie, Veterinärmedizinischen Fakultät, Universität Leipzig.
Insights
This study found that a synthetic humic substance (HS 1500) showed no adverse effects on rat mothers or fetuses during pregnancy and development. Oral administration of HS 1500 is considered safe for treating gastrointestinal issues in pregnant animals.
Area of Science:
- Toxicology
- Developmental Biology
- Environmental Science
Context:
- Investigating the safety of synthetic humic substances (HS 1500) for animal use.
- Assessing potential developmental impacts during critical prenatal and postnatal periods.
Purpose:
- To evaluate the pre- and postnatal developmental effects of oral HS 1500 administration in rats.
- To determine the safety profile of HS 1500 for pregnant animals with gastrointestinal diseases.
Summary:
- Rats received HS 1500 (1000 mg/kg and 2000 mg/kg b.w.) during organogenesis and up to weaning.
- No adverse effects were observed in dams or fetuses at the tested doses.
- A single malformation and minor behavioral differences were not attributed to HS 1500 exposure.
Impact:
- HS 1500 demonstrates a safe profile for use in pregnant animals.
- Supports the potential therapeutic application of HS 1500 in veterinary medicine for gastrointestinal conditions.
- Provides crucial data for risk assessment of synthetic humic substances in animal health.
Abstract:
The influence of a low molecular synthetic humic substance (HS 1500) on pre- and postnatal development of rats was investigated. After oral application of 1000 mg/kg and 2000 mg/kg b. w. HS 1500 during the period of organogenesis (6th to 15th day p. c.) and from 16th day p. c. up to weaning neither adverse effects in the mothers nor in the fetuses were reported. The occurrence of a single malformation (gastroschisis) after application of 1000 mg/kg b. w. from day 6 to 15 of pregnancy, few ossifications of phalanges and differences in swimming behaviour are not regarded as the effect of the substance. In conclusion, the oral use of HS 1500 in the treatment of gastrointestinal diseases in animals during pregnancy is regarded to be riskless.
