Abstract
OBJECTIVE: To assess the effect of interferon (IFN)-alpha on viability of feline corneal epithelial cells, replication of feline herpesvirus (FHV)-1, and virus-induced cytopathic changes. SAMPLE POPULATION: Healthy eyes from 10 recently euthanatized cats. PROCEDURE: 4 replicate primary cultures of feline corneal epithelial cells were grown after the addition of 10(2) to 10(6) IU of IFN-alpha/mL. Cultures were examined every 24 hours for evidence of cytotoxic changes. Viable cell counts and percentage of viable cells were determined 48 hours after initiation of culture. In a separate experiment, cultures of corneal cells were inoculated with FHV-1 and cultured for 72 hours with or without 10(5) IU of IFN-alpha/mL. The FHV-1-infected cultures were evaluated for viral-induced cytopathic effects, and viral titers were determined in samples of culture supernatant. RESULTS: Interferon-alpha did not have cytotoxic effects on corneal epithelial cells at concentrations ranging from 10(2) to 10(6) IU of IFN-alpha/mL. Interferon-alpha at a concentration of 10(5) IU/mL significantly reduced the cytopathic changes and FHV-1 titers. CONCLUSIONS AND CLINICAL RELEVANCE: Lack of in vitro cytotoxic effects and efficacy against FHV-1 infection in primary cultures of feline corneal cells suggests that the in vivo therapeutic effect of IFN-a should be assessed in controlled clinical trials.

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
