| [pharmaceutical preparations from plant products employed in stomatologic diseases]. | two preparations for stomatological use have been introduced, obtained from vegetal extracts of ocimum basilicum l., tilia sp., and symphytum officinalis l. their stability in time was evaluated, and the microbiological activity was assessed in vitro on microbial strains involved in stomatological affections. in clinical experiments good results were obtained in parodonthopathies, in the therapy of lesions developing under prostheses, and in other affections. | 1988 | 2978706 |
| pollen calendar of the city of salamanca (spain). aeropalynological analysis for 1981-1982 and 1991-1992. | we report a study on the contents of airborne pollen in the city of salamanca (spain) aimed at establishing a pollen calendar for the city for the yearly periods of maximum concentrations, relating these with quantifiable atmospheric variables over two two-year periods with an interval of 10 years between them: 1981-82 and 1991-92. the pollen was captured with burkard spore-traps, based on hirst's volumetric method. determinations were made daily and were used to make preparations, previously st ... | 1998 | 9885728 |
| developmental stages and fine structure of surface callus formed after debarking of living lime trees (tilia sp.). | wounding of trees by debarking during the vegetative period sometimes results in the formation of callus tissue which develops over the entire wound surface or on parts of it. this light and transmission electron microscopy study of living lime trees found that the formation of such a surface callus is subdivided into three stages. during the first stage, numerous cell divisions take place in regions where differentiating xylem remains at the wound surface after debarking. this young callus tiss ... | 2002 | 12102533 |
| ectomycorrhizal fungal diversity, tree diversity and root nutrient relations in a mixed central european forest. | knowledge is limited about whether root nutrient concentrations are affected by mixtures of tree species and interspecific root competition. the goal of this field study was to investigate root nutrient element concentrations in relation to root and ectomycorrhizal (em) diversity in six different mixtures of beech (fagus sylvatica), ash (fraxinus excelsior) and lime (tilia sp.) in an old-growth, undisturbed forest ecosystem. root biomass and nutrient concentrations per tree taxon as well as the ... | 2011 | 21636693 |
| Triteleia peyerimhoffi comb. n., a remarkably variable circum-Mediterranean scelionid (Hymenoptera, Platygastroidea). | Triteleia peyerimhofficomb. n. (Kieffer, 1906) is redescribed taking into account its great variability and is considered the senior synonym of Triteleia dubia (Kieffer, 1908), Calliscelio lugens (Kieffer, 1910) and Triteleia striolata Kononova & Petrov, 2000, syn. n. Neotypes are designated for Triteleia dubia and Triteleia peyerimhoffi. Triteleia peyerimhoffi is a new record for Greece, France and Croatia and was reared for the first time from eggs of Orthoptera laid in the dead wood of Quercu ... | 2011 | 22144859 |
