The ‘classical’ model to explain glandular hypofunction in Sjögrens syndrome (SS) is tissue loss secondary to immune attack mediated by a combination of apoptosis and cytotoxic cell death (reviewed recently by Ramos-Casals and Font [1]). In this model, the process of glandular destruction is made self-sustaining by the continued production of novel ‘self ’ antigens, secondary to apoptotic bleb ...

results glandular trichomes composed of capitates and peltate trichomes. the essential oil composition differs. viridiflora and neryl acetate were not identified in yellow glandular trichomes. conclusions it seems that there is no relation between anatomical characteristics of the plant leaves and its essential oil composition. background perovskia abrotanoides karel. is a medicinal plant used ...

It is well known that trichomes protect plant organs, and several studies have investigated their role in the adaptation of plants to harsh environments. Recent studies have shown that the production of hydrophilic substances by glandular trichomes and the deposition of this secretion on young organs may facilitate water retention, thus preventing desiccation and favouring organ growth until th...

Systematic investigation on the family Asteraceae (Compositae) growing throughout in the northern region of Bangladesh was carried out. A total of 36 species under 29 genera of the family Asteraceae were collected and identified. A complete taxonomic account of each species has been given along with their current name, local name, brief description, phenology, basic chromosome number, anatomy a...

Histochemical, micromorphology, ultrastructural and confocal analyses of the trichomes of Micromeria thymifolia (Scop.) Fritsch, were carried out using light microscopy, confocal laser scanning electron microscopy, scanning electron and transmission fluorescent microscopy. Three types of glandular trichomes – peltate, capitate and digitiform and non-glandular trichomes are described on the abax...
