Innovative Glycerin Impregnation Of Female Livestock Genital Organs And Satisfaction Assessment For Veterinary Anatomy Education In Thailand, Paisan Tienthai, Jantima Intarapanya, Pawana Chuesiri

The Thai Journal of Veterinary Medicine

Veterinary anatomy education faces several challenges, including increasing student enrollment, regulatory restrictions on animal use, and limitations of traditional preservation methods. Formalin preservation poses health risks, while plastination is costly and lacks flexibility. The conventional and modified Elnady Techniques present a safer and more cost-effective alternative, offering soft and flexible specimens; however, the adverse features still appear, and some steps require expensive equipment. This study aims to refine these Elnady Techniques, called ‘innovative glycerin impregnation’ for preserving female reproductive organs by reducing costs and simplifying the process using basic equipment. Additionally, veterinary students' satisfaction with glycerin-preserved specimens was compared to …

Faculty, Staff and Students Publications

In mammals, sperm formation is completed in the seminiferous tubules within the testis, and sperm maturation occurs during the epididymal transit of the spermatozoa. Sperm morphology drastically changes when abnormal spermatozoa migrate from the testis to the epididymis. Detailed molecular mechanisms for sperm survival in the epididymis have not been determined yet. Globozoospermia is a cause of male infertility and is characterized by round-headed spermatozoa without acrosomes, an abnormal sperm nuclear membrane, and sperm midpiece defects. Testis expressed 50 (Tex50) is a testis-enriched gene that is expressed in mice and humans. Using CRISPR-Cas9, we generated Tex50 knockout (KO) …
