    The brain-small intestine connection has become important in neurodegenerative diseases in recent years. In particular, the discovery of the relationship between Alzheimer's disease (AD) and the small intestine and the examination of the effects of AD on this tissue are important in this respect. Our study aimed to understand the effects of the experimentally created AD model in rats on the small intestinal tissue and the protective effect of the extract prepared from parsley leaves (PE). The experimental animals were divided into four groups in the study; Control, Scopolamine (Scop), Scop + PE and Scop + Galantamine (GAL). Oxidative stress parameters and activities of some important enzymes were examined in small intestinal tissues taken as a result of the experimental protocol. Additionally, in silico studies were carried out for bioactive molecules found in parsley leaves using data obtained from in vivo enzyme activity results. It was found that parameters examined for the damaged group, Scop, were reversed by PE and GAL treatment. As a result of in silico studies, it was determined that oxypeucedanin and phylloquinone had higher binding affinity than rutin for acetylcholinesterase (AChE). It has been observed that oxidative damage in the small intestine due to AD can be treated by the PE.

    IntroductionPostmenopausal diabetes is a condition that affects millions of women and their quality of life. Also, kidney and small intestine tissues are damaged due to diabetes. The present study aimed to examine the protective effects of an extract prepared from Myrtus communis leaves on kidney and small intestine tissues against experimentally created postmenopausal diabetes. MethodsFor this purpose, experimental rats were randomly divided into six groups (Control; ovariectomy:OVX, diabetic:D, ovariectomy + diabetic:OVX + D, ovariectomy + diabetic + oestrogen:OVX + D+E2, ovariectomy + diabetic + MC: OVX + D+MC) and kidney and small intestine tissues were taken after the experimental procedure. ResultsEvaluations of biochemical parameters (glutathione and glutathione-related enzymes, antioxidant enzymes, etc.) showed that MC had a protective effect on kidney and small intestine tissues in diabetes and ovariectomy groups. ConclusionIt can be suggested that MC extract has a protective effect on small intestine and kidney tissues in postmenopausal diabetes and may be a good herbal source for this purpose.
