question:
Question: Does lactobacillus plantarum 299v reduce enteric bacteria or bacterial translocation in patients undergoing colon resection?
Answer: Lactobacillus plantarum 299v was established in the intestine, but no inhibitory effect on enteric bacteria, bacterial translocation, or postoperative complications was found. The mechanism behind the protective effects of probiotics found in animal and some human studies remain elusive and require further explorations. No adverse effects were recorded after the administration of high doses of Lactobacillus plantarum 299v.
answer:
no


question:
Question: Is cerebral acetylcholinesterase activity decreased in MS patients with cognitive impairment?
Answer: In the patient group regional AChE activities had inverse correlations with Word learning and MMSE (Mini-Mental State Examination) scores. In the group of cognitively deteriorated MS patients no change in cerebral AChE activity, compared with controls, was observed, but within the patient group more pronounced cognitive symptoms were associated with higher cerebral AChE activity.
answer:
no
