A knowledge gap exists regarding DHA/PQP’s cardiac effects, warranting a comprehensive investigation. Approach: This study aimed to assess KROSH (DHA/PQP) impact on albino rat heart histology, examining structural changes and potential cardiotoxicity. 40 albino rats were grouped by KROSH dosage and duration, monitored for weight changes, and heart tissues were examined using hematoxylin and eosin (H & E) staining. Statistical analysis compared to control and treated groups. Results: KROSH administration led to varying rat weight effects, yet not statistically significant. Histological analysis revealed dose and duration-dependent cardiac tissue alterations, including distortion, adipose deposits, artery hypertrophy, fibrosis, and necrosis. These contrasts with prior research documenting DHA/PQP’s non-toxic effects. Conclusion/Recommendation: This study highlights potential KROSH (DHA/PQP) cardiotoxicity concerns through histological changes, underscoring the need for further research into underlying mechanisms and human health implications. Given DHA/PQP’s wide use, these findings should inform safety evaluations and administration practices.展开更多
