چکیده

Introduction: Unstained formalin-fixed whole brain specimens and brain slices do not give satisfactory results for teaching neuroanatomy. In addition, difficulties in obtaining human brains for dissection have increased the demand for more durable brain specimens that have been obtained by the plastination technique. In the present study brain specimens were sliced, fixed and stained using the Mulligan method. Materials and Methods: Plastination was performed after two dehydration methods: standard and stepwise. We measured and compared color fading and shrinkage of the specimens between both methods. Result: There was no color change after dehydration in both methods. Conclusion: According to the results, stained plastinates that have been dehydrated by the stepwise method are suitable for teaching neuroanatomy.

A New Method of Brain Plastination

Introduction: Plastination is a unique technique for preservation of biological specimens used for teaching purposes. The protocol of flexible sheet plastination includes fixation, slicing, dehydration, force impregnation, casting, and curing (Hajian, Rabiei, Fatollahpour & Esfandiary, 2008). The procedure is done by using P87 flexible unsaturated polyester resin and provides heavy, gross, frag...

Oil absorption reduction of eggplant slices during deep fat frying by applying osmotic dehydration pretreatment

Background and Objectives: A fairly large amount of oil is absorbed to the food during deep frying. The aim of this study was to reduce the oil absorption of eggplant slices during frying by using osmotic dehydration pretreatment. Materials and Methods: Using maltodextrin (0, 20, 40% w/v) and sodium chloride (salt, 0, 10, 20% w/v), the effect of osmotic dehydration on different properties of e...

The Effect of Ultrasound-Assisted Osmotic Dehydration Pretreatment on the Convective Drying of Apple Slices (var.Golab)

Drying is one of the widely used methods of food preservation and it is a sensitive food processing operation due to undesirable changes in the quality of dried product. In this study the effect of osmotic dyhedration and ultrasound pretreatment prior to convective drying on quality properties of apple slices was investigated. Apple slices were pretreated by osmotic dehydration in two concentra...
