Objectives:
To detect the changes of (interleukin, IL) -1α, IL-1β and IL-13 mRNA in lung tissue and serum of drown rats, and to explore the potential value for the diagnosis of drowning in forensic practice.
Methods:
Eighteen SD rats were randomly divided into drowning group, blank control group and myocardial infarction group (as control group). The serum of right ventricular, the inferior lobe of right lung and the myocardium were taken from the rats in different groups. The expressions of IL-1α, IL-1β and IL-13 mRNA in the lung tissue and the serum of right ventricular were detected by TaqMan probe method.
Results:
The expression differences of IL-1α, IL-1β and IL-13 mRNA in lung tissue between drowning group and blank control group, myocardial infarction group were not statistically significant (P>0.05). The expression of IL-1β and IL-13 mRNA in serum of right ventricular increased ( P<0.05). The expression differences of IL-1α, IL-1β and IL-13 mRNA in serum between blank control group and myocardial infarction group were not statistically significant (P>0.05).
Conclusions:
The changes of cytokines IL-1β and IL-13 mRNA in the serum of right ventricular of drown rats are statistical significance, which are highly correlated with drowning.

Once about 20-40 ribonucleotides have been joined together by RNA polymerase, a group of enzymes adds a “cap” to the 5’ end of the growing transcript. In this process, a 5’ phosphate is replaced by modified guanosine that has a methyl group attached to it (7-Methyl...
