Abstract

|
|
Objectives : The objective of this study is to analyze the single-dose toxicity of horse placenta hydrolysate extracts.
Methods : Sprague-Dawley rats were chosen for the study. Doses of horse placenta hydrolysate extracts, 2,000 mg/kg, 1,000 mg/kg and 500 mg/kg, were administered to the experimental group, and the same doses of normal saline solution were administered to the control group. This study was conducted under the approval of the Institutional Animal Ethics Committee.
Results : In all 4 groups, no deaths occurred, and the horse placenta hydrolysate extracts administered by oral was over 2,000 mg/kg.
No significant changes in the weight between the control group and the experimental group were observed.
To check for abnormalities in organs and tissues, we used microscopy to examine representative histological sections of each specified organ, the results showed no significant differences in any organs or tissues.
Conclusions : The above findings suggest that treatment with horse placenta hydrolysate extracts is relatively safe. Further studies on this subject should be conducted to yield more concrete evidence.
