The aims of the present study are to investigate the cannabinoid effects on serum
monocyte chemoattractant protein-1 (MCP-1), Troponin-1 ,liver and renal test
parameters. The experimental rats were divided into three groups, the first group served
as a control, and the animals were injected with normal saline. In the second group,
animals were injected with cannabis (5 mg/kg, intraperitonial), while in the third group
animals were injected with cannabis (10 mg/kg). After the course of the experiment,
systolic blood pressure (SBP) tended to reduce significantly in the second dose of
cannabis administered rats. Serum nitric oxide (NO) level slightly increased in dose
dependent manner but it did not reach the level of significance. Serum level of
malondialdehyde (MDA), troponin-T, MCP-1 and serum total bilirubin were
significantly increased in the second dose of cannabis administration as compared to
control rats. Neither triiodothyronin (T3) nor tetraiodothyronin (T4) hormones had
statistically changed in cannabis group comparing with the control rats. Furthermore,
serum uric acid reduced in cannabis group as compared with control. In conclusions, for
the first time, our findings suggested that cannabis could affect immune system through
MCP-1 elevation. As well as, cannabis may affect cardiac and liver functions via
increasing troponin-T and bilirubin levels.
