ABSTRACT: It is well known among plastinators that acetone is a good degreaser when used at room temperature. In fact, the dehydration process is achieved by using acetone at -25o C, followed by a degreasing process utilizing acetone or dichloromethane at room temperature. The objective of this study was to identify the rate and effectiveness that cold acetone (-25o C) has on fat removal during the dehydration process and to compare it with the defatting phase at room temperature. Samples were soaked in -25o C acetone for 21 days (3 baths of 100% acetone) and then 20o C for 21 days (3 baths of 100% acetone). Acetone was changed at 7-day intervals and the “Dirty”/used acetone was collected and total fat content was determined using a rotary evaporator. Over a 42-day period, the samples demonstrated a uniform pattern of decreasing fat extraction during dehydration. However, when degreasing was initiated, a sharp increase of extraction was observed which ended with a steep decline. These findings were supported by mirrored purity readings with an acetonometer. Rate of extraction was greatest during the first seven days of both phases. Dehydration yielded 17.9 % more fat extracted by weight when compared to the defatting phase. This study represents the first report that the dehydration phase may play a more important role in degreasing than the defatting phase itself. Using acetone purity readings with calculated k-values for average rate of extraction data points allows one to quantify and determine a “successful extraction of fat.”","PeriodicalId":36740,"journal":{"name":"Journal of Plastination","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43518530","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ABSTRACT: The lifelike preservation of three-dimensional plant material poses particular challenges, and there is still no established method for it. The aim of the present study was to develop a method to preserve the trapping leaf of a carnivorous pitcher plant in its natural shape and coloration for long-term display in a public exhibition. Fresh pitchers were subjected to one of the following preservation methods: freeze-drying, coating in PDMS, and plastination. The resulting specimens were then compared against fresh and air-dried material. Plastination was found to be superior to the other preservation methods in yielding lifelike specimens for display. In particular, plastinates retained their shape better and exhibited no obvious shrinkage. However, the process altered the coloration significantly due to the loss of chlorophyll and mobilisation of anthocyanins (red–blue pigments) during the dehydration and impregnation stages. Exposure of the finished plastinated specimen to bright light also caused it to turn brown over a period of several weeks. Further work is needed to refine the procedures for plastination of botanical material. In particular, a method should be sought for fixing chlorophyll and other plant pigments. These issues notwithstanding, plastination shows promise as a 3D preservation method to supplement herbarium material and educational displays.","PeriodicalId":36740,"journal":{"name":"Journal of Plastination","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42856883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Department of Pediatric Neurosurgery, Bogdanowicz Memorial Hospital for Children, Niekłańska 4/24, 03-924 Warsaw, Poland. ABSTRACT: S10 silicone technique is the world’s most popular plastination technique. Specimens obtained in S10 plastination retain their shape and color while gaining the hardness and consistency of hard silicone plastic. However, the specimens remain those of tissues and organs, which means that they still constitute biological material susceptible to microbial colonization. Reports of plastinated specimens being infected with various microbial species have been published in the literature. With consideration to the above, this study consisted of swab cultures being collected from surfaces of various organ specimens which had been plastinated using the S10 technique five years earlier. Microbial assays were also performed for the surfaces of anatomical models and dissecting room surfaces frequently touched by the students. As a result, various microfloral species were detected on the dissecting room surfaces, anatomical models, and bone tissue specimens while no bacterial or fungal growth was observed on plastinated samples.","PeriodicalId":36740,"journal":{"name":"Journal of Plastination","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45571540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
