Eight groups were studied: Control_0-intact wounds Control_ss-0.9% NaCl injections MSC injections Control_msc-intact wounds on the opposite side of the body from the MSC group external application of the PCCD external application of a combination of the drugs PCCD + MSC DCh –ointment Dioxomethyltetrahydropyrimidine + Chloramphenicol and DHCB-injections of a deproteinized hemoderivative of calf blood. Two wounds were made on the backs of each of 112 Wistar rats, removing the skin.

Rivista Italiana di Paleontologia e Stratigrafia 126, 783–801. Archives des Sciences de Genève 28, 259–262. Developments in Palaeontology and Stratigraphy 19, 745–757. Throughout the section a trend in the distribution of morphospecies is observed, marked by an increase in the abundance of Aspidolithus parcus parcus and a decrease in the abundance of Aspidolithus parcus expansus in the upper part of the section. parcus parcus (L > 9 µm, b/a 9 µm, b/a <1 and 4-8 perforations). Including the number of perforations: (1) Broinsonia enormis subs. Lauer, 1975) have been measured.įive morphotypes were distinguished at Loibichl section as well as Wolfgring et al. Gardin et al., 2001), as well as the number of perforations in the central area (e.g. For each specimen, the length (L) and width (W) of the coccolith, the b/a ratio of the width of the outer rim/shield (b) versus the small diameter of the central area (a) (e.g. have been measured using JMicroVision software. A total of 1021 specimens with a moderate to good state of preservation of Broinsonia/ Aspidolithus spp. The present study focuses on the light-microscope morphometric analysis of Broinsonia/Aspidolithus group, around the Santonian–Campanian boundary (UC13-UC14a-UC14b) in the Loibichl section (Austrian Eastern Alps).
However, there is a taxonomic problem in the generic attribution of Aspidolithus (without central cross) or Broinsonia (with central cross) (see also Nannotax 3 and Miniati et al., 2020). Changes in coccolith morphometry of the Aspidolithus/Broinsonia group are used to identify subspecies of the group relevant in the Upper Cretaceous. This bioevent is generally near the paleomagnetic reversal from C34n (Long Cretaceous Normal Superchron) to C33r, the primary marker for the base of the Campanian, with a proposed GSSP at Bottachione/Gubbio (Miniati et al., 2021). parca (Stradner, 1963) Bukry, 1969 (of Nannotax3) defines the base of the Campanian. The first occurrence of large Aspidolithus parcus parcus (Stradner 1963) Noël 1969 or Broinsonia parca subsp.
