Perancangan Hewan Coba Model untuk Karsinoma Payudara HER-2 Positif Menggunakan Agen Imunosupresan

Abstract

The development of therapeutic drug for malignancy in Indonesia is often constrained because of the inability to provide animal models for preclinical study. These animal models are an animal model with a malignancy mass which have special characteristics, not just the tumor mass. Animal models that are usually used for this purpose is immunodeficient animals. This animal must be kept in sterile animal care, but the facility is not readily available in Indonesia. The purpose of this study was to develop a method for providing an animal model of nude mice replacement that has fairly low immunity but are still able to live in non-sterile animal care facilities. The study was conducted at the Laboratory Animal and Cytogenetics, Center for Radioisotope and Radiopharmaceuticals Technology, Batan, Serpong in the period of July to November 2014. SKBR-3 cell lines were inoculated on two groups of immunocompetent mice (Mus musculus) strain Balb/c, namely the treatment group (n=8) and controls (n=8). Cyclosporine A as an immunosupressan agent was given only to the treatment group before and after SKBR 3 inoculation. No macroscopically visible tumor growth at the site of inoculation in both of groups. There was a significant difference between the treatment group and the control group in leukocyte levels (p: 0.01), lymphocytes (p: 0.01), monocytes (p: 0.01), and neutrophil segments (p: 0.01). Two treatment groups of mice obtained cloudy degeneration in the liver. This method has significantly reduced the immunity of mice (Mus musclus) strain Balb/c but still cannot grow malignancies in experimental animals.
