## Abstract Studies were designed to demonstrate the need for standardization of shape of samples used as implants to evaluate histotoxicity of polymer materials. Six medicalβgrade polymers (polypropylene, polyethylene, polyurethane, silicone rubber, poly(vinyl chloride), and Teflon) were extruded

Abstract
An evaluation of the biophysical changes of methylcholanthrene induced tumor (M~4~) in laboratory animals receiving four different alloplastic implants was conducted. The implants are silicone, polyether urethane, poly(methyl methacrylate), and bioglass. The tumor was allowed to grow to a large size in 28 days and then removed by shelling it from the surrounding tissue. Three different analytic volumetric measurements were carried; size in cm^3^, volume in milliliters and weight in grams. Statistical analysis on the three different analytic measurements did not disclose any significant differences in tumor growth potential between the control and the experimental groups. We conclude that in this study we were unable to demonstrate any tumor βfacilitationβ effect by any of the implantable polymers used. Therefore, there is no contraindication in using the polymers to reconstruct defects produced by cancer ablative procedures.

## Abstract **Summary:** Implant failure is one of the major concerns in the biomaterials field. Several factors have been related to the fail but in general these biomaterials do not exhibit comparable physical, chemical or biological properties to natural tissues and ultimately, these devices can
## Abstract One of the major obstacles in developing rationale strategies to control inflammation and fibrosis surrounding implants is the lack of a simple and inexpensive __in vivo__ model to screen tissue reactions to various biomaterials and implants. To begin to fill this gap, we have developed
Flow cytometry was used to quantify an inflammatory reaction in vivo as a new approach to evaluating the biocompatibility of biomaterials. The exudate formed inside cylindrical tubes composed of polyvinyl chloride (PVC), silicone elastomer (SIL), or polyurethane (PU) implanted subcutaneously in the
