RESUMO
Rokitansky and Langhans first reported multinucleated giantcells in tuberculous granulomas around a century ago. Inprocess of tissue remodeling and repair the multinucleatedgiant cells (MGCs) acts as inextricable mediators. They alsoaid in removal of various pathogens and foreign materials(Vignery, 2005). Thus, for host survival they have a rolein elimination of foreign substances, damaged tissue, andpathogens. Giant cells are supposed to arise from the monocyteprecursors which forms subsequently to various mechanisms.These cells assume distinctly variable phenotypes dependingupon the mechanism of their formation. This review focuseson the role of the giant cell in oral pathoses such as microbiallesions, cystic lesions, metabolic lesions and cancer.
RESUMO
The present investigation carried out to study the character association and path analysis in twenty three recombinant inbred lines (RILs) of Sabita/Sambamahsuri derivatives and four check varieties of rice (Oryza sativa L.). Character association of the yield attributing traits revealed significantly positive association of grain yield per plant with number of panicles per plant (genotypic), panicle weight, panicle length, number of florets per panicle, number of grains per panicle, kernel breadth and harvest index. Hence, selection for these traits can improve yield. Path coefficient analysis revealed that ten characters viz. days to maturity, panicle length, number of primary branches per panicle, number of florets per panicle, number of grains per panicle, fertility percentage, grain length, kernel breadth, kernel Length/Breadth (L/B) ratio and harvest index had positive direct effect on yield.
