The Effect of Ecstasy Administration During Pregnancy on Mice Fetuses
Bibliographic record
Abstract
Introduction: Ecstasy or 3,4-Methylenedioxymethamphetamine(MDMA) is a psychotropic and addictive substance that young people tend to use it to reduce their psychological and social tensions. The purpose of this study was to assess the influence of ecstasy consumption on the fetus of pregnant mice during the second and third weeks of pregnancy. Methods: 20 adult female mice were randomly selected(5 for control group and 15 for experimental group). Two intraperitoneal injections of ecstasy(5mg/Kg) was used in the experimental group, on 7th and 14th days of pregnancy, while, in the control group, only distilled water was injected intraperitoneally. On 18th day of pregnancy, mice were placed in separate cages. The condition of palate, skull, external ear, eye, fingers and toes and sindactily, weight, and fertility potentials of newborn mice were studied using stereo microscope. Results: From 163 newborn mice in two groups, no abnormalities were observed in the skull and the external ear. There wasn’t any significant difference between male and female sex ratio between two groups (p=.08). Hypoplasia of the fingers was significantly different between the two groups(p<0.001). The frequency of sindactily was not significantly different between two groups(p=0. 11). Female fertility potential was significantly different between two groups(p<0.001). Conclusion: Adminstration of ecstasy during pregnancy may affect the organogenesis and fertility potential of newborn mice. Therefore, more studies are needed in this regard.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
