Quality and quantity comparison study of corrosion casts of bovine testis made using two synthetic kits: Plastogen G and Batson no. 17

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.
