زمينه و هدف: پروتئينهاي خانواده ليپوكالين، آديپوكاينهايي هستند كه با چاقي، ديابت نوع 2 (T2D) و سندرم متابوليك همراه هستند. تمرين ورزشي و تركيبات فعال گياهان داراي اثرات ضدديابتي بوده و ميتوانند در درمان T2D استفاده شوند. در اين مطالعه اثر تمرين ورزشي و خيار تلخ بر رتينول متصل شونده به پروتئين 4 (RBP4)، پروتئين متصل به اسيدچرب-4 (FABP4) و ليپوكالين-2 (LCN2) در مردان T2D بررسي شد.
روش كار: در اين مطالعه كارآزمايي باليني، 36 نفر مرد T2D تهراني انتخاب و بهطور تصادفي به چهار گروه (كنترل، خيارتلخ، تمرين و تمرين+خيار تلخ) تقسيم شدند. گروههاي تمرين بهمدت هشت هفته، هر هفته سه جلسه (با شدت 40 تا 70 درصد ضربان قلب ذخيره و مدت 15 تا 45 دقيقه) در برنامه تمريني هوازي فزاينده شركت كردند. گروههاي خيار تلخ و تمرين+ خيار تلخ، 2000 ميليگرم پودر خشك ميوه خيار تلخ را به مدت هشت هفته (دوبار در روز قبل از صبحانه و شام) مصرف نمودند. دو روز قبل و بعد از اجراي پروتكل، در حالت ناشتا خونگيري انجام شد. داده ها با استفاده از آزمون تي مستقل و ANOVA در سطح معنيداري 0/05

Background & objectives: Lipocalin family proteins, have been identified as adipokines associated with obesity, type 2 diabetes (T2D) and the metabolic syndrome. Exercise training and active compounds of plants have potency as antidiabetic that can be used for treating T2D. We have evaluated the effect of exercise training and Momordica chianti L. on Retinol binding protein-4(RBP4), Fatty acid binding proteins-4 (FABP4) and Lipocalin-2 (LCN2) in Men with T2D.
Methods: In this clinical trial study, 36 T2D men in Tehran were selected and randomly divided into four groups (control, M. charantia, training and M. charantia+training). The training groups participated in a progressive aerobic training for eight weeks, three sessions per week (40% to 70% of the reserved heart rate for 15 to 45 min). The groups of M. charantia and M. charantia+training received 2000 mg of M. charantia for eight weeks (twice a day before breakfast and dinner). Two days before and after the protocol, blood samples were taken in fasting state. Data were analyzed using Independent t test and ANOVA at p<0.05.
Results: The results showed that the RBP4, FABP4 and LCN2 decreased significantly in the experimental groups (p<0.0001). Also, RBP4, FABP4 and LCN2 levels were significantly decreased in the M. charantia+ training group compared to training and M. charantia groups (p<0.05).
Conclusions: Aerobic training and M. charantia may decrease inflammation in T2D patients by decreasing lipocalins. Furthermore, aerobic training along with M. charantia had a better effect.
