The objective of the study was to identify the real obstacles that actors face in the integrated management of children aged 6 - 59 months suffering from SAM at the University Hospital of Mother and Child (CHUME) and the Chad-China Friendship Hospital (HATC) of N’Djamena. Methodology: this is a cross-sectional descriptive and interpretative study conducted from January to October 2023 at the CHUME and HATC of N’Djamena. It is based on questionnaires and direct observation of two hundred and thirty-six (236) parents or guardians of malnourished children admitted to these health facilities. All 236 agreed to participate freely in this study. Results: it appears from this study that the obstacles to the integrated management of malnourished children were: poor care-care relationship (26.7%) permanent product breaks (22.9%), the direct costs of services ranged from 30,000 to 60,000 FCFA (41.53%), drugs used for the treatment of patients came from the street (66.10%), malaria and anemia occupy an important place (27.5%), 57.2% respondents had monthly income below 60,000 CFAF. Conclusion: the present study carried out has identified the real bottlenecks to the integrated management of children suffering from SAM in the therapeutic nutritional units of the city of N’Djamena. .展开更多
目的:研究香椿子多酚提取物(polyphenols from toona sinensis seeds,PTSS)对神经毒素6-羟多巴胺(6-OHDA)诱导的PC12细胞损伤的保护作用。方法:体外培养PC12细胞,实验分为对照组、PTSS组、6-OHDA组及PTSS+6-OHDA组,倒置显微镜下观察各...目的:研究香椿子多酚提取物(polyphenols from toona sinensis seeds,PTSS)对神经毒素6-羟多巴胺(6-OHDA)诱导的PC12细胞损伤的保护作用。方法:体外培养PC12细胞,实验分为对照组、PTSS组、6-OHDA组及PTSS+6-OHDA组,倒置显微镜下观察各组细胞形态;MTT法检测细胞存活率;流式细胞术检测细胞凋亡情况;免疫组织化学染色法检测各组细胞Caspase-3、COX-2和TNF-α的表达变化。结果:PTSS可有效地降低6-OHDA引起的PC12细胞的损伤,增加细胞存活率,减少细胞早期凋亡;降低Caspase-3、COX-2及TNF-α的表达。结论:PTSS对6-OHDA引起的PC12细胞损伤具有明显的保护作用。展开更多
