Abstract
Background: Toxicity studies are relevant in assessing the side effects of chemical substances before they are incorporated into the process of drug development.Introduction: Desplatsia dewevrei is a scarce forest species believed by natives to be nutritive and therapeutic, without scientific evidence though. Thus, this study was aimed at investigating the possible toxicity of short- and long-term oral administration of D. dewevrei using Wistar rats.Methods: 0, 30 100, and 1000 mg/kg of D. dewevrei were daily administered p.o for 3 and 28 days to Wistar rats consisting of four animals (two females, two males) per group. Hemotoxicity and liver function tests were done using automated machines from ERMA Inc. RT-PCR method was used to study the regulation of intestinal glucose transporter 4 (GLUT4), glucose transporter 2 (GLUT2), glucagon-like peptide-1 (GLP-1), pancreatic insulin, KCJN5, and L-type voltage-gated calcium channel genes (CACNAIA).Results: No morphological or hematological signs of toxicity were observed. Liver function test showed an elevated level of high-density lipoprotein (HDL-C) in the treatment group (100 mg/kg). The lethal dose (LD<sub>50</sub>) of D. dewevrei extracts were above 1000 mg/kg as no mortality was observed at the highest regimen dose used. Up-regulation of pancreatic insulin and down-regulation of intestinal GLUT-2 suggest that the plant may contain therapeutic constituents.Conclusion: Short- or long-term administration of D. dewevrei is relatively safe.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
