BP device will be implanted under fascia group-A, operated subjects. A lumbar 4-5 cm incision will be performed, splaying of the skin and subcutaneous layers, then will be incised the fascia plane, with a blunt dissection the fascia will be separated from muscles. Fifteen rats will receive 2x2cm2 samples of BP (Buckypaper) in a pocket created between muscular fascia and large muscles. The rough opaque surface will face the muscle surface and the smooth brilliant surface will face the lower muscular fascia surface, without fixation with stitches. Then the scar will be sutured with absorbable stitches on the fascia incision edge and not absorbable stitches on the skin.

A lumbar 4-5 cm incision will be performed, splaying of the skin and subcutaneous layers, then will be incised the fascia plane, with a blunt dissection the fascia will be separated from muscles. Fifteen rats (hereafter defined as BPR16-BPR30) will receive 2x2cm2 samples of PP (polypropylene) in a pocket created between muscular fascia and large muscles. The polypropylene prosthesis will be fixed to the muscle with absorbable sutures surface and then the muscular fascia will be sutured over the prosthesis, with absorbable stitches on the fascia. Not absorbable stitches will be sutured on the skin.

bio-compatibility of Buckypaper implanted in a lumbar scar by evaluation of liver function by SGOT(Serum Glutamic Oxaloacetic Transaminase), SGPT(Serum Glutamic PyruvateTransaminase), GGT(gamma glutamyl transferase), ALP(alkaline phosphatase) and fractionated bilirubin, PT(Prothrombin Time), APTT/PTT(Activated partial thromboplastin time), Fibrinogen. The evaluation will be performed at the beginning of experimentation and at the sacrifice after 35 days and will be evaluated the difference (delta) before and after implantation of BP

We will investigate the effects of exposition to BP fragments on healthy tissues and CaCo2 cells (Cancer Colon cluster), MCF-7 (Michigan Cancer Foundation-7), a breast cancer cell line, and hSCs (healthy smooth-muscle cells) of thyroid artery.

bio-compatibility of Buckypaper implanted in a lumbar scar by evaluation of kidney by BUN and blood creatinine, and creatinine clearance. The evaluation will be performed at the beginning of experimentation and at the sacrifice after 35 days and will be evaluated the difference (delta) before and after implantation of BP

bio-compatibility of Buckypaper implanted in a lumbar scar by evaluation of marrow function by CBC(Complete Blood Count) formula, lymphocyte subpopulations, C-reactive protein, erythrocyte sedimentation rate. The evaluation will be performed at the beginning of experimentation and at the sacrifice after 35 days and will be evaluated the difference (delta) before and after implantation of BP
