Although corrosion casting has been implemented for almost five centuries, the choice of resin has a strong influence on the effectiveness of casting vessel formations. Our aim was to compare quality and quantity features of two groups of corrosion casts made using two kits: Plastogen G resin and Batson no. 17 resin.
Thirty corrosion casts were made of testicular arterial vessels (15 made using Plastogen G and 15 made using Batson no. 17) and their shape, colour, fragility and flexibility were evaluated. The following parameters were measured: maximal width of corrosion cast of testis, maximal length of centripetal and centrifugal arteries, diameter of testicular artery and its terminal branches. Based on these measurements, five indexes were calculated (Iq1-Iq5).
Generally both groups of corrosion casts demonstrated similar attributes. Only the rami tunicales minores displayed higher fragility and lower flexibility in the Plastogen G group than the Batson no. 17 group. The only observed quantitative difference was that Iq3 was significantly lower in the Plastogen G group (0.71 ± 0.01) than in Batson no. 17 group (0.79 ± 0.01; p = 0.0092).
The two corrosion cast groups displayed similar qualitative and quantitative attributes. Batson no. 17 appears to be a good resin for three-dimensional visualisation of extra- and intratesticular arterial vessels.
尽管腐蚀铸型技术已应用了近五个世纪，但树脂的选择对铸型血管形成的效果有很大影响。我们的目的是比较使用两组试剂盒（Plastogen G树脂和巴特森17号树脂）制作的两组腐蚀铸型的质量和数量特征。
制作30个睾丸动脉血管的腐蚀铸型（15个使用Plastogen G制作，15个使用巴特森17号制作），并评估其形状、颜色、脆性和柔韧性。测量以下参数：睾丸腐蚀铸型的最大宽度、向心动脉和离心动脉的最大长度、睾丸动脉及其终末分支的直径。基于这些测量值，计算五个指标（Iq1 - Iq5）。
总体而言，两组腐蚀铸型表现出相似的属性。仅在Plastogen G组中，睾丸小叶支显示出比巴特森17号组更高的脆性和更低的柔韧性。唯一观察到的数量差异是，Plastogen G组的Iq3（0.71±0.01）显著低于巴特森17号组（0.79±0.01；p = 0.0092）。
两组腐蚀铸型在质量和数量属性上相似。巴特森17号似乎是用于睾丸外和睾丸内动脉血管三维可视化的良好树脂。
