Abstract We compared the individual effects of mitiglinide and glibenclamide administered in combination with the dipeptidyl peptidase-IV (DPP-IV) inhibitor sitagliptin on plasma DPP-IV activity and blood glucose levels in rats with streptozotocin-nicotinamide-induced type 2 diabetes (STZ-NA rats). We examined the inhibitory activity of mitiglinide and glibenclamide as well as their combination with sitagliptin on plasma DPP-IV activity in STZ-NA rats. The oral glucose tolerance test (OGTT) was used to compare effects of mitiglinide, glibenclamide, and their combination with sitagliptin on blood glucose levels in STZ-NA rats. Mitiglinide and glibenclamide did not inhibit rat DPP-IV and did not influence the inhibitory effect of sitagliptin on rat plasma DPP-IV activity. In STZ-NA rats, plasma glucose levels were stronger suppressed by a combination of mitiglinide and sitagliptin than by either drug used alone. However, no clear effect of the combination of glibenclamide and sitagliptin was observed. These results indicate that the combination of mitiglinide and sitagliptin has a lower risk of hypoglycemia in the rats with induced type 2 diabetes compared with the combination of glibenclamide and sitagliptin. The combination of mitiglinide and sitagliptin can be a promising combination for the treatment of diabetic patients.

AbstractThe hydrolysate of Oncorhynchus keta (chum salmon) milt was found to exhibit strong inhibitory activity against dipeptidyl peptidase-IV (DPP-IV), and the hypoglycaemic effect of these salmon milt peptides (SMPs) was confirmed using oral starch tolerance tests in Sprague–Dawley rats. Specifically, the oral administration of SMPs at a dose of 300 mg/kg body weight for 1 week resulted in a significant decrease in the blood glucose level of the rats 60 min after starch consumption compared with the control. The bioassay-guided separation of SMPs, using a combination of column chromatographic techniques, led to the identification of 12 active di-, tri- and tetrapeptides, including four novel DPP-IV inhibitory peptides, namely Phe-Pro-Val-Gly, Leu-Pro-Val-Leu, Val-Pro-Phe-Pro and Ile-Pro-Leu. Among these 12 peptides, Ile-Pro contributed the most (1.3%) to the total DPP-IV inhibitory activity of SMPs. Therefore, SMPs may have the potential to be used as a suppressor of postprandial hyperglycaemia and to be considered a promising functional food material for the prevention of type II diabetes.

ABSTRACT Severe periodontitis is known to aggravate diabetes mellitus, though molecular events related to that link have not been fully elucidated. Porphyromonas gingivalis, a major pathogen of periodontitis, expresses dipeptidyl peptidase 4 (DPP4), which is involved in regulation of blood glucose levels by cleaving incretins in humans. We examined the enzymatic characteristics of DPP4 from P. gingivalis as well as two other periodontopathic bacteria, Tannerella forsythia and Prevotella intermedia, and determined whether it is capable of regulating blood glucose levels. Cell-associated DPP4 activity was found in those microorganisms, which was effectively suppressed by inhibitors of human DPP4, and molecules sized 73 kDa in P. gingivalis, and 71 kDa in T. forsythia and P. intermedia were immunologically detected. The k cat/Km values of recombinant DPP4s ranged from 721 ± 55 to 1,283 ± 23 μM−1s−1 toward Gly-Pro-4-methylcoumaryl-7-amide (MCA), while those were much lower for His-Ala-MCA. Matrix-assisted laser desorption ionization–time of flight mass spectrometry (MALDI-TOF MS) analysis showed His/Tyr-Ala dipeptide release from the N termini of incretins, glucagon-like peptide 1 (GLP-1) and glucose-dependent insulinotropic polypeptide, respectively, with the action of microbial DPP4. Moreover, intravenous injection of DPP4 into mice decreased plasma active GLP-1 and insulin levels, accompanied by a substantial elevation in blood glucose over the control after oral glucose administration. These results are the first to show that periodontopathic bacterial DPP4 is capable of modulating blood glucose levels the same as mammalian DPP4; thus, the incidence of periodontopathic bacteremia may exacerbate diabetes mellitus via molecular events of bacterial DPP4 activities.

Significant Difference

Objective: Diabetes mellitus is a leading cause of death and disability in the world and its prevalence is predicted to rise to 10% by 2030. Hence, this study is conducted with objectives to find out the effect of aerobic exercises and resisted exercises on blood glucose levels in type 2 diabetes mellitus (T2DM) subjects and to compare the effect of both exercises on blood glucose level.Method: The comparative study was conducted at Krishna Institute of Medical Sciences Deemed University, Physiotherapy department, Karad. 30 participants with age group between 30 and 65 years were taken. Subjects were selected as per inclusion and exclusion criteria. Group A (15) participants were given aerobic exercise on static bicycle, and Group B (15) participants were given resistance training using dumbbells and weight cuffs for 5 days/week for 4 weeks. Diet recommendations were given to every participant.Results: Statistical analysis was performed using paired and unpaired t-test. Analysis showed statistically extremely significant difference in fasting blood glucose level and postprandial blood glucose level in both the groups (p≤0.0001).Conclusion: Thus, this study concludes that both aerobic exercises and resistance training prove to be beneficial in controlling blood glucose levels in T2DM subjects.
