Das Mittelmeergebiet ist eine Region im so genannten Etesienklima (benannt nach dem sommerlichen Etesien-Wind in Griechenland, S. 266ff), auch Mittelmeerklima oder mediterranes Klima genannt, das sich durch trockene, heise Sommer und milde, regenreiche Winter auszeichnet (Zonobiom IV nach Walter, 1991).

The genus Helleborus is represented in the Northwestern Balkans by 8 species. Some of them (H. atrorubens, H. foetidus (newcomer, introduced as well as escaped from culture), H. niger, and H. orientalis (newcomer, escaped from culture)) are rather easy for determination and discrimination. While other 4 species (H. dumetorum, H. multifidus, H. odorus, and H. viridis) are really difficult for determination because of their narrow morphological similarity, which also is realized a wide variety in leaf shape. The distribution areas of last 4 species overlap in the Northwestern Balkans, so that there are no really clear borders of their distribution. Dominating species in this region is H. multifidus, and especially common there is its subsp. istriacus. Other 3 species are rare and are therefore often overlooked and the herbarium specimens are frequently misidentified as H. multifidus. Moreover, all these 4 species produce number of hybrids, and as a result all kind of transistions between these taxa could be found. In particular, 11 hybrides could be confirmed for this region. The hybrid between H. dumetorum and H. multifidus is described here as Helleborus ×mucheri.

40 children with clinical diagnosis of bronchial asthma aged 8--14 years, 39 with allergic disposition, were investigated. Acute therapeutic and protective effect on frequency of asthmatic attacks, pulmonary auscultation and lung function (FEV1, PF, FVC) by application of Fenoterol and Ipratropium as combination aerosol were registered. Over a period of 4 weeks we could reduce the frequency of attacks nearly to the half. 10 and 20 minutes after aerosol application we showed a good improvement of pulmonary ventilation. Only on children with severe asthma bronchiale an exclusive treatment with Berodual seems to be of modest protective effect.
