Sažetak
We describe the effects of nitric oxide (NO) agonists and antagonists and the influence of a novel organoprotective pentadecapeptide BPC 157, on the development of pulmonary hypertension syndrome and tissue lesions in chicks. Acute toxicity, which includes single dose application of saline (1ml ip), BPC 157 (10micrograms/kg b.w.), L-NAME (NO antagonist, doses 50, 100, 150 mg/kg bw) and L-arginine (NO agonist, 100 mg/kg bw with their combination L-NAME+BPC 157 ; L-Name+L-arginine) was investigated. In this experiment pathohistological examination of the spleen, heart, liver and lungs and hematological analysis was conducted. In the chronic toxicity experiment, the animals were treated daily for 5 weeks witl L-NAME (10 mg/kg bw), L-arginine (100 mg/kg bw), BPC 157 (10micrograms/kg bw) and their combinations (L-Name + BPC 157 ; L-NAME + L-arginine) ip.Seven animals from each group, including controls (saline 1ml ip) were killed every week. Application of L-NAME caused oulmonary hypertension syndrome (PHS) in the treated chicks, which was prevented by the simultaneous application of L-arginine and BPC 157. Pathohistological examination of both acute and chronic toxicity revealed that L-NAME caused severe tissue damage (myocardial and hepatic cell necrosis, necrosis of the lymphoid cells in the spleen) while L-arginine provoked predominantly congestion, edema and hemorrhages in all organs. The effect of L-NAME was successfully inhibited by the application of L-arginine and BPC 157 but the latter substance did not cause any tissue or organ damage. Hematological analysis shows significant hemoglobin and leucocyte number decrease in the L-NAME treated groups of chicks.
