Dr. Tuba Parlak Ak</dc:contributor><dc:description xml:lang="tr">Bu çalışma, NG-nitro-L-arjinin metil ester (L-NAME) ile oluşturulan deneysel hipertansiyon modelinde Naringin'in Apelin ve Nükleer faktör eritroid 2-ilişkili faktör 2 (Nrf-2) ekspresyonları üzerine etkisinin araştırılmasını amaçlamıştır. Araştırmada, 28 adet erişkin Spraque-Dawley cinsi erkek sıçan her grupta 7'şer adet olmak üzere rastgele seçilip toplam 4 gruba ayrıldı. Kontrol grubuna; 14 gün boyunca günlük 0.5 ml zeytinyağı oral gavajla verildi. L-NAME grubuna; 14 gün boyunca günlük 40 mg/kg/BW dozunda L-NAME zeytinyağı ile birlikte oral gavajla verildi. L-NAME+NAR grubuna; 14 gün boyunca günlük 40 mg/kg/BW dozunda L-NAME ve akabinde 80 mg/kg/BW dozunda Naringin (NAR) zeytinyağı ile birlikte oral gavajla verildi. NAR grubuna; 14 gün boyunca günlük 80 mg/kg/BW dozunda Naringin zeytinyağı ile birlikte oral gavajla uygulandı. Tüm sıçanların çalışmanın 0., 7. ve 14. günlerinde ölçülen kan basıncı değerleri açısından gruplar arasında istatistiksel olarak anlamlı bir farklılık izlendi (p&lt;0.05). Kontrol grubu ile karşılaştırıldığında L-NAME grubu sıçanların sistolik kan basıncı (SKB) değerlerinde anlamlı bir artış olduğu (p&lt;0.05) tespit edildi. L-NAME grubuna kıyasla L-NAME+NAR grubunda ise SKB değerlerinde anlamlı bir azalış olduğu (p&lt;0.05) belirlendi. Kontrol grubuna kıyasla L-NAME grubu sıçanlara ait böbrek dokularında belirgin histopatolojik değişiklikler tespit edilirken, L-NAME grubuna kıyasla L-NAME+NAR grubunda bu değişikliklerin hafiflediği belirlendi. Kontrol grubuna kıyasla L-NAME grubu sıçanlara ait böbrek dokusunda azalmış Apelin reseptörü (APLNR) ve Nrf-2 immünoreaktivitesi saptanırken (p&lt;0.05), L-NAME grubuna kıyasla L-NAME+NAR grubunda artmış APLNR ve Nrf-2 immünoreaktivitesi dikkati çekti (p&lt;0.05). Sonuç olarak, Naringin'in deneysel hipertansiyon modelinde APLNR ve Nrf-2 immünoreaktiviteleri üzerine düzenleyici etkilerinin olduğu sonucuna varılmıştır.</dc:description><dc:description xml:lang="en">This study aimed to investigate the effect of Naringin on Apelin and Nuclear factor erythroid 2-related factor 2 (Nrf-2) expressions in the experimental hypertension model created with NG-nitro-L-arginine methyl ester (L-NAME). In the study, 28 adult Spraque-Dawley male rats were randomly selected, 7 in each group, and divided into a total of 4 groups. Control group; 0.5 ml of olive oil was given daily by oral gavage for 14 days. L-NAME group; L-NAME was given by oral gavage together with olive oil at a daily dose of 40 mg/kg/BW for 14 days. L-NAME+NAR group; L-NAME at a daily dose of 40 mg/kg/BW and then Naringin (NAR) at a dose of 80 mg/kg/BW were given by oral gavage together with olive oil for 14 days. NAR group; Naringin was administered by oral gavage together with olive oil at a daily dose of 80 mg/kg/BW for 14 days. A statistically significant difference was observed between the groups in terms of blood pressure values of all rats measured on the 0th, 7th and 14th days of the study (p&lt;0.05). It was determined that there was a significant increase (p&lt;0.05) in the systolic blood pressure (SBP) values of the L-NAME group rats compared to the control group. It was determined that there was a significant decrease in SBP values in the L-NAME+NAR group compared to the L-NAME group (p&lt;0.05). While significant histopathological changes were detected in the kidney tissues of L-NAME group rats compared to the control group, these changes were found to be attenuated in the L-NAME+NAR group compared to the L-NAME group. While decreased Apelin receptor (APLNR) and Nrf-2 immunoreactivity was detected in the kidney tissue of L-NAME group rats compared to the control group (p&lt;0.05), increased APLNR and Nrf-2 immunoreactivity was noted in the L-NAME+NAR group compared to the L-NAME group (p&lt;0.05). As a result, it was concluded that Naringin had regulatory effects on Apelin and Nrf-2 immunoreactivities in the experimental hypertension model.</dc:description><dc:publisher>Munzur University</dc:publisher><dc:date>2024</dc:date><dc:type>Master Thesis</dc:type><dc:identifier>https://rdlopen.rawdatalibrary.net/r/munzur/7002</dc:identifier><dc:language>tr</dc:language><dc:rights>info:eu-repo/semantics/openAccess</dc:rights><dc:type>info:eu-repo/semantics/masterThesis</dc:type><dc:identifier>https://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/7002</dc:identifier></oai_dc:dc></metadata></record></GetRecord></OAI-PMH>
