塑化标本在畜禽解剖学教学中的应用

生物塑化技术是目前国际上最先进的生物标本保存技术,其原理是利用液态高分子化合物或多聚物代替生物标本中的水分,并通过硬化处理达成组织塑化,制成的塑化标本具有无味、无毒、可用手直接触摸、无需防腐液保存、持久耐用等特点。黑龙江八一农垦大学动物科技学院购置了一批畜禽塑化标本并已在课堂教学中应用,使师生体验到塑化标本所具有的浸泡标本和模型所无法替代的优点。塑化标本能够清晰呈现一些细微的解剖结构特征,在教学过程中无论是教师使用塑化标本示教还是学生自己辨认,均不会因标本具有刺激性和毒性而影响观察。使用塑化标本示教更直观,使学生更易接受,从而提高了教学质量。

Application of Plastinated Specimens in Teaching of Anatomy of the Domestic Animals and Fowls

Biological plasticizing technology is currently the most advanced biological specimen preservation technology. Its primary principle is that replacing the moisture in biological specimens with liquid polymer compounds or multi-polymer and subsequently the tissues are plastinated by hardening treatment. The plastinated specimens are non-toxic and tasteless, and it is safe to be touched directly by hands. It is durable and its preservation is antiseptic solutions free. A batch of plastinated specimens of domestic animals and fowls are purchased by College of Animal Science and Veterinary Medicine of Heilongjiang Bayi Agricultural University, and they have already been applied in the classroom teaching. Compared with immersed specimens and models, irreplaceable advantages of the plastinated specimens are experienced by the teachers and undergraduates. Subtle anatomical structure characteristics can be exhibited by the plastinated specimens. Neither teachers nor undergraduates will be affected by the irritation and toxicity of the specimens during the process of teaching and observation. The teaching of Anatomy of the Domestic Animals and Fowls becomes more intuitive and acceptable, which is helpful for improving the teaching quality.
