| Purpose: Type 1 diabetes mellitus (T1DM) has dramatically increased in recent years, especially
in young people, and limits the life quality of the patients involved. Thus, many researchers are
performing extensive studies to find alternative treatments for DM.
Methods: Here, we evaluated the improvement effects of the heat-killed Actinomycetales
species, including Gordonia bronchialis, and Tsukamurella inchonensis in streptozotocin (STZ)-
diabetic rats by biochemical, immunological, and histopathological examinations.
Results: The present findings exhibited a dramatic and progressive alteration in the serum levels
of interleukin-6 (IL-6), IL-10 and tumor necrosis factor-α (TNF-α) in the diabetic group, which
were related to the blood glucose and insulin levels, oxidative stress defense (evaluated by TAC
and MDA activities), and the pancreas biochemical indicators (such as amylase and lipase).
More importantly, the present results were consistent with the histopathological findings, which
included cellular degeneration, vascular congestion, hemorrhage, focal necrosis associated
with mononuclear cell infiltration. Interestingly, all of the diabetic changes in the blood serum
and tissues improved remarkably in the treated groups by Actinomycetales species.
Conclusion: Surprisingly, most of the current diabetic complications effectively attenuated
after oral administration of both Actinomycetales species, particularly with a high dose of T.
inchonensis. Thus, it is concluded that the heat-killed Actinomycetales species can prevent and
improve the progression of T1DM and its various complications profoundly. |
