In the present investigation, the seed extract of V. vinifera was evaluated for antistress activity in normal and stress induced rats. Furthermore, the extract was studied for nootropic activity in rats and in-vitro antioxidant potential to correlate its antistress activity.<\/p>\n<p style=\"text-align: justify\"><strong>METHODS: <\/strong><br \/>\nFor the evaluation of antistress activity, groups of rats (n = 6) were subjected to forced swim stress one hour after daily treatment of V. vinifera extract. Urinary vanillylmandelic acid (VMA) and ascorbic acid were selected as non-invasive biomarkers to assess the antistress activity. The 24 h urinary excretion of vanillylmandelic acid (VMA) and ascorbic acid were determined by spectrophotometric methods in all groups under normal and stressed conditions. The nootropic activity of the extract as determined from acquisition, retention and retrieval in rats was studied by conditioned avoidance response using Cook&#039;s pole climbing apparatus. The in vitro antioxidant activity was determined based on the ability of V. vinifera to scavenge hydroxyl radicals.<\/p>\n<p style=\"text-align: justify\"><strong>RESULTS:<\/strong><br \/>\nDaily administration of V. vinifera at doses of 100, 200 and 300 mg\/kg body weight one hour prior to induction of stress inhibited the stress induced urinary biochemical changes in a dose dependent manner. However, no change in the urinary excretion of VMA and ascorbic acid was observed in normal animals at all the doses studied. The cognition, as determined by the acquisition, retention and recovery in rats was observed to be dose dependent. The extract also produced significant inhibition of hydroxyl radicals in comparison to ascorbic acid in a dose dependent manner.<\/p>\n<p style=\"text-align: justify\"><strong>CONCLUSION:<\/strong><br \/>\nThe present study provides scientific support for the antistress (adaptogenic), antioxidant and nootropic activities of V. vinifera seed extract and substantiate the traditional claims for the usage of grape fruits and seeds in stress induced disorders.<\/p>\n","protected":false},"template":"","mots_cles":[],"class_list":["post-50704","resume","type-resume","status-publish","hentry"],"acf":{"adresse":"Pharmacology Division, Department of Pharmaceutical Sciences Andhra University, Visakhapatnam-530 003, Andhra Pradesh, India. satyanarayana_sreemantula@rediffmail.com","annee":"2005","mois":"1","numero":"5:1","page":"1","auteurs":[{"ID":50699,"post_author":"0","post_date":"2018-12-04 05:21:22","post_date_gmt":"2018-12-04 04:21:22","post_content":"","post_title":"Sreemantula","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"sreemantula","to_ping":"","pinged":"","post_modified":"2018-12-04 05:21:22","post_modified_gmt":"2018-12-04 04:21:22","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/sreemantula\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":50700,"post_author":"0","post_date":"2018-12-04 05:21:24","post_date_gmt":"2018-12-04 04:21:24","post_content":"","post_title":"Nammi","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"nammi","to_ping":"","pinged":"","post_modified":"2018-12-04 05:21:24","post_modified_gmt":"2018-12-04 04:21:24","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/nammi\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":50701,"post_author":"0","post_date":"2018-12-04 05:21:25","post_date_gmt":"2018-12-04 04:21:25","post_content":"","post_title":"Kolanukonda","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"kolanukonda","to_ping":"","pinged":"","post_modified":"2018-12-04 05:21:25","post_modified_gmt":"2018-12-04 04:21:25","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/kolanukonda\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":50702,"post_author":"0","post_date":"2018-12-04 05:21:26","post_date_gmt":"2018-12-04 04:21:26","post_content":"","post_title":"Koppula","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"koppula","to_ping":"","pinged":"","post_modified":"2018-12-04 05:21:26","post_modified_gmt":"2018-12-04 04:21:26","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/koppula\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":50703,"post_author":"0","post_date":"2018-12-04 05:21:28","post_date_gmt":"2018-12-04 04:21:28","post_content":"","post_title":"Boini","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"boini","to_ping":"","pinged":"","post_modified":"2018-12-04 05:21:28","post_modified_gmt":"2018-12-04 04:21:28","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/auteur\/boini\/","menu_order":0,"post_type":"auteur_resume","post_mime_type":"","comment_count":"0","filter":"raw"}],"sources":[{"ID":49469,"post_author":"0","post_date":"2018-12-04 04:57:30","post_date_gmt":"2018-12-04 03:57:30","post_content":"","post_title":"BMC complementary and alternative medicine","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"closed","post_password":"","post_name":"bmc-complementary-and-alternative-medicine","to_ping":"","pinged":"","post_modified":"2018-12-04 04:57:30","post_modified_gmt":"2018-12-04 03:57:30","post_content_filtered":"","post_parent":0,"guid":"https:\/\/aprifel-pp.mentalworks.biz\/fr\/source\/bmc-complementary-and-alternative-medicine\/","menu_order":0,"post_type":"source","post_mime_type":"","comment_count":"0","filter":"raw"}]},"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v23.6 (Yoast SEO v23.6) -
