AIM： To investigate the potential of bone marrow mononuclear cells （BM-MCs） in the regeneration of hepatic lesions induced by Schistosoma mansoni （***） chronic infection. METHODS： Female mice chronically infected with *** were treated with BM-MCs obtained from male green fluorescent protein （GFP） transgenic mice by intravenous or intralobular injections. Control mice received injections of saline in similar conditions, Enzyme-linked immunosorbent assay （ELISA） assay for transforming growth factor-beta （TGF-β）, polymerase chain reaction （PCR） for GFP DNA, immunofluorescence and morphometric studies were performed. RESULTS： Transplanted GFP^＋ cells migrated to granuloma areas and reduced the percentage of liver fibrosis. The presence of donor-derived cells was confirmed by Fluorescence in situ hybridization （FISH） analysis for detection of cells bearing Y chromosome and by PCR analysis for detection of GFP DNA. The levels of TGF-β, a cytokine associated with fibrosis deposition, in liver fragments of mice submitted to therapy were reduced. The number of oval cells in liver sections of ***-infected mice increased 3-4 fold after transplantation. A partial recovery in albumin expression, which is decreased upon infection with ***, was found in livers of infected mice after cellular therapy. CONCLUSION： In conclusion, transplanted BMCs migrate to and reduce the damage of chronic fibrotic liver lesions caused by ***.

Mimosa tenuiflora and Piptadenia stipulacea are commonly accepted as drought-tolerant species but little is known about their response to drought followed by ***,the interplay between leaf water potential and osmotic adjustment on photo synthetic and growth parameters of these species was examined.A greenhouse study was conducted in a split-plot design with two water conditions in the main plots(control;drought followed by rehydration),and eight sampling times in the subplots(1,4and 7 days of drought,and 1,3,6,12,and 17 days of rehydration).Plant water status and biochemical changes were assessed as well as leaf gas exchange and subsequent *** drought stress,both species maintained a low leaf water potential throughout the day by accumulating compatible solutes,thus allowing a rapid and full recovery of water status when *** these plants minimized water loss by closing their stomata,neither showed stomatal limitations to *** inhibition of this process during drought was possibly related to mesophyll limitations as well as to a reversible downregulation of photo systems,along with adjustments of their *** deficits also triggered morphological adaptations at the whole plant level,leading to reduced growth,mainly of the shoots in *** and the roots in ***.
