Pineapple extract may help Alzheimer's patients

An extract derived from pineapple stem may potentially improve the symptoms of Alzheimer's disease, according to a study conducted in mice. Alzheimer's is a neurodegenerative disease generally characterised by gradual memory loss due to increased levels of amyloid-beta protein in the brain. The affected patients are not able to remember things.
In severe cases, people lose the ability to respond to their environment, carry on a conversation and, eventually, control movement.
Researchers at Lovely Professional University in Phagwara, Punjab noted that the current treatment is not effective in managing the long-term effects of Alzheimer's disease on patients' quality of life.
The study, recently published in the journal NeuroToxicology, found that the compound bromelain could improve Alzheimer's disease-related behaviour symptoms in mice.
The behaviour symptoms were supported by the results of biochemical and histopathological -- microscopic examination of tissue -- studies, the researchers said. Biochemical studies included evaluation of activity of acetylcholinesterase, an enzyme that regulates neurotransmission and antioxidant parameters in mice brains which were significantly improved by the treatment with bromelain, they said.
"We also found significant amelioration of levels of the beta-secretase enzyme, beta-amyloid, brain-derived neurotrophic factor, tumour necrosis factor-alfa and interleukin-6 in the mouse brain after treatment with bromelain," said study corresponding author Navneet Khurana, Professor at the School of Pharmaceutical Science, LPU. -- PTI
