Diabetes sepsis on Wistar rat strain () induced by streptozotocin and bacteria .

BACKGROUND AND AIM

Sepsis is characterized by loss of control of the inflammatory response, which can be triggered by various microorganisms and toxic secretions. The mortality rate increases due to impaired endothelial function caused dysfunctional organ systems. Diabetes is closely related to sepsis. The study aimed to determine the method of using animal models of sepsis diabetes through a combination of streptozotocin (STZ) and infection based on biological marker parameters.

MATERIALS AND METHODS

A total of 30 male Wistar rats of 2.5-3 months old weighing approximately 150-250 g body weight (BW) divided into six treatment groups with five replications per group were used in the study. Treatment A was negative control (healthy rats) and Treatment B was the positive control (with diabetes) where rats were given STZ dose at 45 mg/kg BW on day 8 intraperitoneally (IP). The blood glucose was measured on day 10, Treatment C was a positive control (bacteria), rats inoculated with with a concentration of 10 CFU/mL on day 8 given IP and observed sepsis conditions on day 10. Treatment group (D, E, and F): Rats given STZ dose at 45 mg/kg BW on day 8 by IP and measured blood glucose on day 10, then inoculated with with different concentrations of 10 CFU/mL, 10 CFU/mL, and 10 CFU/mL on the 10 day, respectively, and were later observed the condition of sepsis on day 12. Data on diabetes bacteremia were quantitative used blood glucose levels, the bacterial count, and C-reactive protein (CRP) and were analyzed using the one-way analysis of variance test with a confidence level of 95%. Physical examination (temperature and respiration) is qualitative.

RESULTS

Physical examination showed that all treatments had a normal temperature, an increased pulse in Groups D, E, and F and a decrease in respiratory rate in the treatment of E and F, the bacteria found in the vital organs in all groups, and CRP levels were not significantly different at all.

CONCLUSION

Animal model of diabetes sepsis can be observed through a combination of pancreas damage, and respiration, the bacteria in the vital organs.
