Study type

Animal study using FTIR spectroscopy to assess aortic wall changes after unilateral adrenalectomy and BPC 157 treatment
“This study focused on the presentation of blood vessels, aortic wall remodeling in rats after unilateral adrenalectomy, assessed by Fourier Transform Infrared (FTIR) spectroscopy [1], and the effect of the stable gastric pentadecapeptide BPC 157 as a therapy [1,2].”

Subjects

Male albino Wistar rats
“The study was conducted with appropriately randomized male albino Wistar rats, 12–16 weeks of age, with 280 g body weight, self-breeding in the Department of Pharmacology, Faculty of Medicine, Zagreb, Croatia.”

Sample size

6 animals per group per time point
“Randomization was performed using a computer-generated random number sequence with block randomization to ensure equal group sizes (n = 6 animals per group per time point) across all treatments and postoperative intervals.”

Duration

Assessments performed at 15 minutes, 5 hours, and 24 hours post-surgery
“Abdominal aortas were collected at 15 min, 5 h, and 24 h after unilateral adrenalectomy for the FTIR spectroscopy assessment.”

Reported findings

BPC 157 treatment resulted in clear separation of aortic spectra from control samples at all time points
“BPC 157 (10 ng/kg intragatrically immediately after unilateral adrenalectomy) produced a clear, reproducible separation of aortic spectra from control samples at all time points.”
Significant spectral changes were observed in amide I, amide II, and lipid C-H stretching bands
“The main discriminatory spectral signatures were observed in three regions, including amide I and amide II (protein-related bands, consistent with collagen/elastin contributions) and lipid C–H stretching bands.”
Spectral signatures indicated early extracellular matrix reinforcement and membrane preservation
“These spectral signatures are consistent with early extracellular matrix reinforcement and membrane preservation in the vascular wall and align with the recovering effect on the lesions in counteraction of the severe vascular and multiorgan failure, attenuation/elimination of thrombosis and blood pressure disturbances in various occlusion/occlusion-like syndromes.”
