ABSTRACT
BACKGROUND: Failure to thrive (FTT) is a common problem of children especially in underdeveloped countries. In addition to its short-term adverse health effects, it is associated with long-term behavioral and cognitive defects. One of the recommended treatment modalities for FTT is using synbiotics. Due to high prevalence of FTT with undefined organic causes and failure of most medications on treatment of this type of FTT, we decided to search the effect of synbiotics on these patients. MATERIALS AND METHODS: A randomized, triple-blinded, placebo-controlled trial study was done from 2011 to 2012. A number of 84 patients were randomly assigned to intervention and control groups. The synbiotics sachets were administered to study group for 6 months. The growth indices were measured at the beginning of the trial after 3 and 6 months, and compared with control. RESULTS: Variance analysis of observations showed improvement of growth indices in both groups. The increase in weight was significantly higher in synbiotics group than in controls (P < 0.05). The corresponding figure was not significant for height and head circumference (P > 0.05). At the beginning of the trial, the mean weights were 10.25 ± 0.20 kg and 10.750 ± 0.160 kg in intervention and control groups, respectively, Meanwhile, after 6 months, the mean weights of two groups became 12.280 ± 0.190 and 11.760 ± 0.17 kg in intervention and control groups, respectively. This result has confirmed that the effect of synbiotics is significant on weight gain of our patients. CONCLUSION: Our findings support beneficial effects of synbiotics in weight gain of children with FTT.
ABSTRACT
Hepatocyte growth factor (HGF) has opposite biological activities in regulating apoptosis, also underlying molecular mechanisms are not clearly defined. We investigated HGF ability to inhibit cell death, which was induced by Doxorubicin, a DNA damaging agent. Also Survivin and XIAP mRNA levels were compared in HGF treated and non-treated cells. Cell proliferation and death were assessed using MTT assay and dye exclusion tests. Quantitative real-time PCR was used to evaluate Survivin and XIAP expression levels after treatment with HGF. ELISA was performed to quantify HGF secretion in the selected cancer cell lines media. HGF appeared to have inhibitory effect on Doxorubicin induced cell death in all of the studied cell lines. It had minimal effect on XAIP and Survivin expression levels in MRC-5, MOLT-4 and AGS cell lines; except for XIAP expression level in AGS cell line, which was increased substantially after treatment. Surprisingly, in KG-1 cell line, XIAP and Survivin expression levels were significantly reduced after HGF treatment. Although several members of IAP gene family are reported to play role in HGF mediated cytoprotective pathway, we showed that XIAP and Survivin do not seem to be involved.
