Integrated pancreatic microcirculatory profiles of streptozotocin‐induced and insulin‐administrated type 1 diabetes mellitus
OBJECTIVE: As an integrated system, pancreatic microcirculatory disturbance plays a vital role in the pathogenesis of type 1 diabetes mellitus (T1DM), which involves changes in microcirculatory oxygen and microhemodynamics. Therefore, we aimed to release type 1 diabetic and insulin‐administrated mic...

description | OBJECTIVE: As an integrated system, pancreatic microcirculatory disturbance plays a vital role in the pathogenesis of type 1 diabetes mellitus (T1DM), which involves changes in microcirculatory oxygen and microhemodynamics. Therefore, we aimed to release type 1 diabetic and insulin‐administrated microcirculatory profiles of the pancreas. METHODS: BALB/c mice were assigned to control, T1DM, and insulin‐administrated groups randomly. T1DM was induced by intraperitoneal injection of streptozotocin (STZ). 1.5 IU insulin was administrated subcutaneously to keep the blood glucose within the normal range. After anesthetizing by isoflurane, the raw data set of pancreatic microcirculation was collected by the multimodal device– and computer algorithm–based microcirculatory evaluating system. After adjusting outliers and normalization, pancreatic microcirculatory oxygen and microhemodynamic data sets were imported into the three‐dimensional module and compared. RESULTS: Microcirculatory profiles of the pancreas in T1DM exhibited a loss of microhemodynamic coherence (significantly decreased microvascular blood perfusion) accompanied by an impaired oxygen balance (significantly decreased PO(2), SO(2), and rHb). More importantly, with insulin administration, the pathological microcirculatory profiles were partially restored. Meanwhile, there were correlations between pancreatic microcirculatory blood perfusion and PO(2) levels. CONCLUSIONS: Our findings establish the first integrated three‐dimensional pancreatic microcirculatory profiles of STZ‐induced and insulin‐administrated T1DM. |
