“…These patterns of body surface coincided in genus level with those reported previously [8,9]. It may support a hypothesis that the ciliates of the genus Epidinium is rather closely related to those of Entodiniinae than Diplodiniinae [7].…”

ABSTRACT. Rumen ciliate species and composition were surveyed on the reindeer kept in Inner Mongolia, China. As a result of survey, all the reindeer had the same 18 species of 8 genera of the ciliates in their rumen. Appearance of Entodinium parvum is the first record in this host species. Of the species detected, 15 species including Entodinium anteronucleatum, E. bicornutum, Enoploplastron confluens and Epidinium gigas which have been detected only from reindeer were common with those in the reindeer kept in the other areas, such as Alaska, Russia and Finland, indicating that every rumen ciliate faunae in reindeer has high similarity to each other, and suggesting that these hosts have been isolated from the other ruminants for long time and established characteristic ciliate fauna. The ci liate density was estimated as 1.1-2.5 × 10 6 /ml, which value was fairly higher than those in domestic ruminants. Surface structures of characteristic species were observed by SEM. KEY WORDS: ciliate, host specificity, rumen protozoa.

Surface modifications of poly(ether imide) (PEI) membranes with carboxylic groups were tested in comparison to pure PEI and poly(ethylene terephtalate) (PET) for their ability to support attachment, growth and function of human umbilical vein endothelial cells (HUVEC) in respect to endothelization of the above materials. Flat sheet PEI membranes were modified by covalent binding of iminodiacetic acid (IDA) for different periods of time (1 to 30 min) to obtain surfaces with various content of carboxylic groups. In addition, fibronectin (FN) and fibrinogen (FNG) preadsorption on the various membranes were studied on their effect on HUVEC behaviour. Results show a decreased protein adsorption and HUVEC adhesion, growth and function in terms of prostacyclin production with an increase carboxylic groups.Preadsorption of the membranes with FN or FNG promoted activity of HUVEC, which became superior to cells on PET. FN-coated membranes were found to be better substrate for HUVEC adhesion and prostacyclin production, while on FNG-coated membranes cells grew better. Overall it can be concluded that PEI is a promising materials for endothelial cells immobilization as it is needed for improving the hemocompatibility of cardiovascular devices.

“…However, it has been pointed out that such materials occasionally cause pulp irritation [1][2][3][4][5] . Furthermore, there are many reports on the cytotoxic effects of the hydrophobic compounds included in composite resins, such as Bis-GMA and TEGDMA or their analogues [6][7][8][9][10][11][12][13][14][15][16][17][18][19] , which is also related to the problem of environmental estrogens by bisphenol A. The relationship between the three-dimensional structure of environmental estrogens and the toxicity (biological activity) has been studied 20,21) .…”

The purpose of this study was to evaluate the cytotoxicity of acrylic and methacrylic acid (AA and MA), propanoic acid and isobutylic acid (PRA and IBA) which were the corresponding saturated carboxylic acids, 2-hydroxylethyl methacrylate and acrylate (HEMA and HEA), and hydroquinone (HQ). The growth of the fibroblast when exposed to AA decreased with increase of the acid, and was less than when exposed to MA. The growth when exposed to their corresponding saturated acids, PRA and IBA, showed a similar tendency to AA and MA. The growth of fibroblasts exposed to 5 mmol/L HEMA after 4 days and 3 mmol/L HEMA after 6 days was significantly different compared with that without HEMA. The growth in 1, 3, and 5 mmol/L of HEA after 2 days was markedly decreased compared with that without HEA, and the cells were probably lifeless. The growth when exposed to HQ was extremely lower than their acids.
