ABSTRACT Background: Neurosurgery and ophthalmology residents need many years to improve microsurgical skills. Laboratory training models are very important for developing surgical skills before clinical application of microsurgery. A simple simulation model is needed for residents to learn how to handle microsurgical instruments and to perform safe dissection of intracranial or intraorbital nerves, vessels, and other structures. Materials and Methods: The simulation material consists of a one-year-old fresh cadaveric sheep cranium. Two parts (Part 1 and Part 2) were designed to approach structures of the orbit. Part 1 consisted of a 2-step approach to dissect intraorbital structures, and Part 2 consisted of a 3-step approach to dissect the optic nerve intracranially. Results: The model simulates standard microsurgical techniques using a variety of approaches to structures in and around the orbit and the optic nerve. Conclusions: This laboratory training model enables trainees to gain experience with an operating microscope, microsurgical instruments and orbital structures.

AbstractIntraventricular tumors present difficult challenges to the neurosurgeon. Neurosurgeons have begun to explore the possibilities of the endoscope in the complete resection of solid intraventricular tumors. The learning curve is considered steep when dealing with such lesions endoscopically. The aim of this study was to develop a laboratory training model for pathological intraventricular neuroendoscopic surgery. Thirty formalin-fixated, latex-injected cadaveric heads were used. The contrast-enhancing tumor polymer, Stratathane resin ST-504 derived polymer (SRSDP), was injected into the lateral ventricle via Frazer’s point under direct endoscopic visualization and real-time fluoroscopic guidance. Neurosurgeon participants at a ventricular endoscopic course then performed an endoscopic approach to the intraventricular tumor model lesion via an ipsilateral frontal burr hole. The properties of the SRSDP mixture could be manipulated through varying concentrations of source materials in order to achieve a desired consistency and allow for piecemeal resection. Tumor could be injected into the lateral and third ventricles. The tumor model allowed participants to compare both normal and pathological endoscopic anatomy in the one specimen. Our novel injectable tumor model can assist neurosurgeons preparing themselves for the challenges associated with a piecemeal resection of a solid lesion in the lateral or third ventricle.

Accurate estimation of the size of spheroid organelles from thin sectioned material is often necessary, as uniquely homogenous populations of organelles such as vessicles, granules, or nuclei often are critically important in the morphological identification of similar cell types. However, the difficulty in obtaining accurate diameter measurements of thin sectioned organelles is well known. This difficulty is due to the extreme tenuity of the sectioned material as compared to the size of the intact organelle. In populations where low variance is suspected the traditional method of diameter estimation has been to measure literally hundreds of profiles and to describe the “largest” as representative of the “approximate maximal diameter”.

Lipid cytochemistry has not yet advanced far at the EM level. A major problem has been the loss of lipid during dehydration and embedding. Although the adoption of glutaraldehyde and osmium tetroxide accelerate the chemical reaction of lipid and osmium tetroxide can react on the double bouds of unsaturated lipid to from the osmium black, osmium tetroxide can be reduced in saturated lipid and subsequently some of unsaturated lipid are lost during dehydration. In order to reduce the loss of lipid by traditional method, some researchers adopted a few new methods, such as the change of embedding procedure and the adoption of new embedding media, to solve the problem. In a sense, these new methods are effective. They, however, usually require a long period of preparation. In this paper, we do research on the fiora nectary strucure of lauraceae by the rapid-embedding method wwith PEG under electron microscope and attempt to find a better method to solve the problem mentioned above.
