The assessment of soil contamination and natural self-purification dynamic soil processes can be accomplished by numerous eco-hygienic and sanitary means without additional pollution. Among these, sublethal earthworm avoidance behavior tests have proven to be most effective. The aim of this case study was to determine the soil pollution risk in five large swine farms in Romania by using an avoidance behavior test as a screening tool with adult specimens of the earthworm Eisenia fetida (ISO 17512-1:2008 qualitative test). Two soil samples were extracted at 100 to 300 m (328 to 984 ft) and 500 to 1,000 m (1,640 to 3,280 ft) distance from each swine farm, and a single sample was taken at 1,300 m (4,265 ft) distance. The results were analyzed statistically using the Anderson-Darling Normality Test (NIST/SEMATECH) and have shown that out of the 11 soil samples, the earthworms strongly avoided (p ≤ 0.005) 4 of them, confirming a potential eco-risk. The majority of the samples avoided by the specimens were collected at the 500 to 1,000 m range. However, the soil sample taken 1,300 m away from the farm showed that, at this distance, the soil had no sign of contaminants, as earthworms preferred the testing soil to the reference sample. In our opinion, this simple assessment, which produces fast and accurate results, should be included in a battery of tests as a helpful early qualitative screening tool in soil contamination assessment procedures to reveal a potential eco-risk. © 2016 Soil and Water Conservation Society.

The objective was the cytoarchitecture evaluation of known steroid dependent target tissues after administering of testosterone, compared to action of its more active ester, nortestosterone (nandrolone decanoate) in castrated rat males in the aim of Hershberger bio test. Study was performed on 30 castrated male Wistar rats, aged between 35 and 39 days, in peripubertal period, divided into five groups. Androgen doses administration begun at the rats’ age of 49 days. Animals were injected i.m., daily, for 10 consecutive days as follows: Aquatest (Balkan Pharmaceuticals Ltd., Moldova) testosterone aqueous solution: Testosterone I group (0.4 mg/animal); Testosterone II (0.8 mg/animal); (Deca-Durabolin, Balkan Pharmaceuticals); nandrolone decanoate oily solution: Nortestosterone I (1.5 mg/kg body weight); Nortestosterone II (7.5 mg/kg body weight) and Control (White sesame oil, Manicos, Romania, 0.1 mL/animal). Gonadectomy (GDX) induced modifications of target tissues wet weight accompanied by important modifications in cytoarchitecture. Changes following exogenous administration of testosterone and nortestosterone decanoate were found in: liver (granular dystrophy, mega-mitochondria, tubular intumescences), prostate (increasing of the structural elements), seminal vesicles (hyalinosis, thickening of cell walls and the hyaline presence), levator ani-bulbocavernosus muscle (muscle fibbers dilacerations), bulbourethral glands (muscular fibbers rarefaction by fluid accumulation) demonstrating the disruptor activity especially for overdosed nandrolone decanoate. © 2014, Editura Academiei Romane.

Background: Given its numerous biologically active components, Euphorbiaceae has been found to be a large plant family and polyvalent with quite interesting therapeutic activity that can be studied. Materials and Methods: The ixodicidal activity of Euphorbia cyparissias extracts was studied in vitro and in vivo. Tested concentrations were 10, 5, 2, 1, 0.5 and 0.25%. Results: For the in vitro study, conducted on field-collected female specimens of Dermacentor marginatus and Haemaphysalis punctata, the efficacy results showed that the ticks died after exposure in the case of 10, 5, and 2% tincture concentrations. The effects appeared after 30 minutes and became more visible 120 minutes after each exposure. The statistical differences regarding the used concentrations were found to be: F=6.51,df=5,P<0.001.TheinvivostudyoftheefficacyofE.cyparissiasconcentrationswasperformedon35naturallyinfestedsheepandon30 bovines parasitized with Ixodes ricinus, sprayed with tincture and glycerinate dilutions (bovines) on days 0 and 7. The results revealed detrimental effects on the survivability of female ticks, the most prominent being the reduction of their movement capacity. In sheep in vivo efficiency observed within 24 hrs varied, between 1 and 23% for D. marginatus and between 7 and 27% for H. punctata and respectively between2 and 53% after 24 hrs, for I. ricinus, comparable effects being also found 72 hrs after the second administration of Euphorbia extracts. Conclusion: Extracts from E. cyparissias may be used, with results, as an ecologic alternative tick control management method, being a cheap solution, with a sizeable role in reducing the use of synthetic and/or other harming and resistance source ixodicidal conditionings. © 2014, African Ethnomedicines Network.
