Swiss ethnoveterinary knowledge on medicinal plants - a within-country comparison of Italian speaking regions with north-western German speaking regions

BACKGROUND: Ethnoveterinary knowledge in Europe may play an important role as a basis for sustainable treatment options for livestock. Aims of our study were (a) to compare the ethnoveterinary practices of two culturally and sociodemographically different regions of Switzerland, (b) to compare results with earlier ethnoveterinary studies conducted in Switzerland and in adjacent Italian regions and, (c) to evaluate possible reasons for regional differences in European ethnoveterinary medicine. METHODS: 25 interviews were conducted in 2014 in all Italian speaking regions (ItR) of Switzerland, and 31 interviews were held in five north-western German speaking Cantons (GeC). Semi-structured questionnaires were used to collect detailed information regarding plant species, mode of preparation, dosage, route of administration, category of use, origin of knowledge, frequency of use, and satisfaction with outcomes of the treatments. RESULTS: A total of 162 homemade remedies in ItR and 219 in GeC were reported, out of which 125 and 145, respectively, were reported to contain only one plant species (homemade single species herbal remedy report, HSHR). 44 ItR and 43 GeC plant species were reported to treat livestock, of which only a half were used in both regions. For each HSHR, we classified the treatment intention of all use reports (UR), leading to a total of 205 and 219 UR in ItR and GeC respectively. While cattle were the most often treated livestock species in both study regions, in ItR 40% of UR were administered to small ruminants. Main indications in both regions were gastrointestinal diseases and skin afflictions, but in ItR a high number of URs were reported as antiparasitics. URs were mainly handed down from the past generation, but in GeC the source of knowledge for 20% of URs were from courses. Regarding the used plant species, ItR showed a higher concordance with Swiss than Italian studies, but with some differences to all regions. A total of 22 (14 ItR; 8 GeC) plant species in this study have not been reported before in ethnoveterinary studies of Swiss and Italian alpine regions. CONCLUSIONS: ItR and GeC, show differences and similarities with respect to their own ethnoveterinary practices and earlier Swiss and Italian ethnoveterinary studies. Linguistic, geographical, as well as social and farm-structural conditions influence the regional ethnoveterinary knowledge. However, political borders seem to be more important than language or geographical barriers

Treatment of organic livestock with medicinal plants : a systematic review of European ethnoveterinary research

Background: The EC Regulation for Organic Farming states that organic livestock should be treated preferably with phytotherapeutic products. In spite of the high importance of organic livestock in Europe, primarily ruminants, today almost no phytotherapeutic product is registered for livestock. Also, scientific information regarding veterinary phytotherapy is rare. The aim of this paper is to find approaches to cope with health problems of organic ruminants in Europe on the basis of findings from the European ethnoveterinary medicine (EuEVM). Methods: A systematic review of ethno-biomedicinal papers was conducted with the aid of the Scopus database, and 75 papers, from European countries were analyzed regarding ethnoveterinary information. Results: A total of 590 plant species referring to 102 different plant families are reported to be used for animal treatment, with Asteraceae, Fabaceae and Lamiaceae being the most important families. The traditional use of some plant species (e.g. mallow, chamomile, wormwood) corresponds with findings from recent scientific literature. The large number of less studied plant species, such as white lupin as an antiparasitic herb, and Helleborus spp. as potential immunostimulatory agent, opens an interesting field for future research. Conclusions: In general, EuEVM provides interesting treatment approaches for gastrointestinal and dermatological disorders as well as parasitosis. Findings regarding disorders of female genital or respiratory tract are less consistent. Nevertheless, EuEVM offers a solid basis for stimulating research in veterinary phytotherapy in Europe with a perspective to solve animal health problems in organic or even nonorganic ruminant production

Effect of Chronic Inhibition of Converting Enzyme on Renal Handling of Salt and Water: A Study on a Pediatric Population

Background/Aims: The effect of angiotensin-converting enzyme inhibition (ACEi) is amply documented in several pathological conditions. However, there are few reports about the effect of chronic ACEi on salt and water balance. The present work evaluates the effect of chronic ACEi on salt and water balance in a population of children receiving enalapril chronically in order to reduce albuminuria elicited by a uremic hemolytic syndrome. Methods: Nine children aged from 9 to 19 years with normal glomerular filtration rate, normotension and with urinary concentration capacity preserved were treated with enalapril with doses ranging between 0.1 and 0.30 mg/kg/day. Diuresis, urinary absolute and fractional excretion of Na+, K+ and urea, creatinine clearance, osmolal clearance and tubular water reabsorption were measured under three experimental procedures: (1) with free access to water; (2) with a water load and (3) with water restriction. In the last group urinary antidiuretic hormone (ADH) was measured. These tests were performed in a paired way, just before starting ACEi treatment and after 6 months of enalapril treatment. Results: Enalapril treatment diminished the urinary concentration capacity without affecting Na+ and K+ urinary excretion. Creatinine clearance was not modified except in the condition of water load where a fall in it was found after ACEi. ADH increased after enalapril treatment in children under water restriction. Conclusion: In these children chronic ACEi decreases urinary concentration capacity.Fil: Dieguez, S. M.. Gobierno de la Ciudad de Buenos Aires.

Diagnosing infection with small ruminant lentiviruses of genotypes A and B by combining synthetic peptides in ELISA

The major challenges in diagnosing small ruminant lentivirus (SRLV) infection include early detection and genotyping of strains of epidemiological interest. A longitudinal study was carried out in Rasa Aragonesa sheep experimentally infected with viral strains of genotypes A or B from Spanish neurological and arthritic SRLV outbreaks, respectively. Sera were tested with two commercial ELISAs, three based on specific peptides and a novel combined peptide ELISA. Three different PCR assays were used to further assess infection status.The kinetics of anti-viral antibody responses were variable, with early diagnosis dependent on the type of ELISA used. Peptide epitopes of SRLV genotypes A and B combined in the same ELISA well enhanced the overall detection rate, whereas single peptides were useful for genotyping the infecting strain (A vs. B). The results of the study suggest that a combined peptide ELISA can be used for serological diagnosis of SRLV infection, with single peptide ELISAs useful for subsequent serotyping.Funded by CICYT (AGL2010-22341-C04-01 and AGL2013-49137-C3-1R) and Navarra's Government (IIQ010449.RI1 and IIQ14064.RI1).

Nuevos datos de carbones y maderas fósiles de Pinus pinaster Aiton en el Holoceno de la Península Ibérica

The study of ligneous fossil remains (charcoal and wood) corresponding to three sites located in the interior of the Iberian Peninsula is presented. The chronologies established by means of radiocarbon or relative dating (archaeological) situate all the samples in the last phase of the Holocene. In the three deposits Pinus pinaster has been identified and there have being made other taxonomic contributions. A review of previous Pinus pinaster findings registered in the Peninsula is exposed and other considerations are made on the importance of this taxon in the Iberian vegetal landscape during the end of the Quaternary.Se ha realizado un estudio de restos fósiles leñosos correspondientes a tres yacimientos del interior de la península Ibérica: Hontalbilla (Segovia), Yecla (Murcia) y Castillejos (Badajoz). Las cronologías establecidas mediante datación absoluta (radiocarbono) o relativa (arqueológica) sitúan todas las muestras en la última fase del Holoceno. En los tres yacimientos se ha identificado Pinus pinaster, realizándose además otras aportaciones taxonómicas. Se reúnen los datos conocidos de macrorrestos de P. pinaster registrados en la Península y se realizan consideraciones sobre la importancia de este taxon en el paisaje vegetal ibérico durante el final del Cuaternario

Anthracological evidence suggests naturalness of Pinus pinaster in inland southwestern Iberia

The study of well-preserved archaeological charcoals in the pre-Roman Iron Age settlement of Castillejos II (Badajoz, Spain) is used to reconstruct environmental conditions and land-use practices in vegetation landscapes in the southwest of the Iberian Peninsula before the arrival of Roman civilization. The results support that, while evergreen Quercus forests dominated during the Holocene, Pinus pinaster existed as a natural element of southwestern Iberian Peninsula vegetation. Although its presence could be linked to anthropogenic disturbance or fire history, it is suggested that P. pinaster populations survived during the Holocene in the region, mixed with oaks or in monospecific stands in mountain enclaves. This hypothesis contrasts with previous assumptions that P. pinaster was not autochthonous in the area

Comparison and evaluation of experimental mediastinitis models: precolonized foreign body implants and bacterial suspension inoculation seems promising

BACKGROUND: Post-sternotomy mediastinitis (PSM) is a devastating surgical complication affecting 1–3% of patients that undergo cardiac surgery. Staphylococcus aureus is one of the most commonly encountered bacterial pathogen cultured from mediastinal samples obtained from patients with PSM. A component of the membrane of the gram positive bacteria, lipoteichoic acid, stimulates the blood monocytes and macrophages to secrete cytokines, radicals and nitrogen species leading to oxido-inflammatory damage. This seems to be responsible for the high mortality rate in PSM. For the evaluation of the pathogenesis of infection or for the investigation of alternative treatment models in infection, no standard model of mediastinitis seems to be available. In this study, we evaluated four mediastinitis models in rats. METHODS: The rats were divided into four groups to form different infection models. Group A: A suspension of 1 × 10(7 )colony-forming units Staphylococcus aureus in 0,5 mL was inoculated from the right second intercostal space into the mediastinum. Group B: A hole was created in the right second intercostal space and a piece of stainless-steel implant with a length of 0.5 cm was inserted into the mediastinum and a suspension of 1 × 10(7 )cfu bacteria in 0,5 mL was administered via the tail vein. Group C: Precolonized stainless-steel implant was inserted into the mediastinum. Group D: Precolonized stainless-steel implant was inserted into the mediastinum and the bacteria suspension was also injected into the mediastinum. On the 10(th )day, rats were sacrificed and the extension of infection in the mediastenae was evaluated by quantitative cultures. Myeloperoxidase activity (MPO) and malondialdehyde (MDA) levels were determined in the sera to evaluate the neutrophil activation and assess the inflammatory oxidation. RESULTS: The degree of infection in group C and D were 83.3% and 100% respectively (P < 0.001). MDA levels were significantly higher in these two groups than the others (P < 0.001). CONCLUSION: Infected implants and high bacterial concentration administration were the two important components that played a significant role in the outcome of a successful infection in mediastinum in a rat model
