The authors have previously reported the development of a novel technique for sampling and preparing tissue slides for routine microscopic examination, without the use of a microtome. Termed "RAMP" (Rapid Adhesive Mediated Procedure), this simple, albeit somewhat crude, technique holds promise as a method that can be used in the field by veterinary practitioners for rapid microscopic evaluations to obtain early preliminary estimates of the nature of a mass or lesion. We incorporated the use of this method into a gross anatomy course in an attempt to gauge its utility for novices in tissue sampling and histology slide preparation. By having each group of students take a tissue sample from their cadaver, the activity simulated an actual necropsy situation in which practitioners in the field might use the technique. Because students were able to follow their specimen from sampling to microscopic examination, the activity provided a valuable integration of their learning of gross and microscopic anatomy. We conducted an evaluation of the process and the resulting slides with two successive classes of students. We conclude that the RAMP method is reasonably successful in the hands of individuals not trained in tissue preparation; was well received by the students as a valuable learning tool; and could potentially yield useful histological information for practicing veterinarians. Limitations of the method are also discussed.
作者此前曾报道过一种用于采集和制备组织切片以进行常规显微镜检查的新技术,该技术无需使用切片机。这种被称为“RAMP”(快速粘合剂介导程序)的简单技术虽然有些粗糙,但有望成为兽医从业者在现场用于快速显微镜评估的方法,以便对肿块或病变的性质获得早期初步估计。我们将这种方法的使用纳入了一门大体解剖学课程,试图评估其在组织采样和组织学切片制备方面对新手的实用性。通过让每组学生从他们的尸体上采集组织样本,该活动模拟了实际尸检情况,即现场从业者可能会使用该技术的情况。由于学生能够跟踪他们的标本从采样到显微镜检查的全过程,该活动为他们对大体解剖学和微观解剖学的学习提供了有价值的整合。我们对连续两届学生的操作过程和所得切片进行了评估。我们得出结论,RAMP方法在未经组织制备培训的人员手中相当成功;作为一种有价值的学习工具,受到了学生的好评;并且有可能为执业兽医提供有用的组织学信息。我们还讨论了该方法的局限性。
