    Abstract To better understand the relationships within the Asteroideae and Inuleae, the structure of the pollen exine was investigated in seven genera and nine species of the subtribe Inulinae using LM, TEM and SEM. All taxa have a senecioid pattern of exine. The tectal complex consists of three main layers that differ in thickness and morphology: a tectum, a columellar layer, and a layer consisting of the basal region of the columellae. The absence or the vestigial condition of the foramina is considered as a plesiomorphy within the Asteroideae. All taxa have a complex apertural system that consists of an ecto-, a meso-, and an endoaperture. These apertures intersect respectively the tectal complex, the foot layer and the upper part of the endexine, and the inner layer of the endexine. A continuous transition among the different species of Inulinae was found for all the quantitative characters examined. This relative homogeneity of the pollen morphological characters enhances the naturality of the subtribe Inulinae

    There were discovered 7 cases of diffuse lung diseases (DLD) (5 β€” pneumoconiosis, 2 β€” fibrosing alveolitis) among 60 workers (welding and metal-polishing workers) with chronic non-specific lung diseases (CNLD). Five cases of pneumoconiosis were also found among 16 welding workers who worked indoors. Other 11 welding workers and 9 of 15 patients with chronic bronchitis without roentgenographic signs of DLD had similar changes in bronchoalveolar lavage fluid in comparison with patients having DLD changes. It was recomended to consider the large number of lymphocytes in lavage fluid as an evidence of the risk of the DLD development. The large number of neutrophyls, eosinophyls, T-4+ cells, the fagocytic activity of alveolar macrophages, and the activity of natural killers in lavage fluid could testify about the onset of DLD.Π‘Ρ‹Π»ΠΎ ΠΎΠ±Π½Π°Ρ€ΡƒΠΆΠ΅Π½ΠΎ 7 случаСв Π΄ΠΈΡ„Ρ„ΡƒΠ·Π½Ρ‹Ρ… Π»Π΅Π³ΠΎΡ‡Π½Ρ‹Ρ… Π·Π°Π±ΠΎΠ»Π΅Π²Π°Π½ΠΈΠΉ (Π”Π›Π—) (5 β€” ΠΏΠ½Π΅Π²ΠΌΠΎΠΊΠΎΠ½ΠΈΠΎΠ·, 2 β€” Ρ„ΠΈΠ±Ρ€ΠΎΠ·ΠΈΡ€ΡƒΡŽΡ‰ΠΈΠΉ Π°Π»ΡŒΠ²Π΅ΠΎΠ»ΠΈΡ‚) срСди 60 Ρ€Π°Π±ΠΎΡ‡ΠΈΡ… (сварщики ΠΈ ΡˆΠ»ΠΈΡ„ΠΎΠ²Ρ‰ΠΈΠΊΠΈ ΠΌΠ΅Ρ‚Π°Π»Π»Π°) с хроничСскими нСспСцифичСскими заболСваниями Π»Π΅Π³ΠΊΠΈΡ… (Π₯НЗЛ).
