Antidiabetic Properties of Stingless Bee Pollen in High-Fat Diet FED-Low Dose STZ Induced Experimental T2DM Rats

Abstract

Diabetes mellitus (DM) is a multisystem metabolic disease because of either insulin insufficiency or ineffectiveness. Individuals with DM continuously measure their blood glucose levels during fasting and after eating in order to manage their condition effectively. glucose levels during fasting and after eating in order to manage their condition effectively. Despite the availability of several drugs, there is no treatment proven to be perfect due to adverse side impacts as well as reduced long-term efficacy. Moreover, the excessive formation of free radicals has been linked to diabetes progression, development, as well as complications. As a result, there is a need to explore new medicines without side effects, preferably derived from natural products. Therefore, this study analyzes the antidiabetic properties of stingless bee pollen scientifically. This natural product was fed a high-fat diet and low streptozotocin doses in experimental rats with T2DM. An oral glucose tolerance test aimed investigate stingless bee pollen effect on glucose homeostasis. An insulin toleration test was executed to obtain stingless pollen influence on insulin sensitivity. This study measures Insulin resistance with HOMA-IR. Oral administration of stingless bee pollen for 30 days raised glucose homeostasis in T2DM rats, as shown by the OGTT, ITT, and HOMA-IR results. In addition, this treatment significantly improved changes in glycated hemoglobin, fasting blood glucose, protein, uric acid, urea, as well as creatinine levels. The activity changes of ALP, AST, and ALT liver enzyme markers in T2DM rats were nearly normalized after given with stingless bee pollen. The activity of carbohydrate metabolism enzymes includes pyruvate kinase, glucokinase, glucose-6-phosphatase, glucose-6-phosphate dehydrogenase, fructose-1,6-bisphosphatase and lactate dehydrogenase in T2DM rats’ liver tissue. This change was significantly restored to near-normal levels after stingless bee pollen treatment.
