Animal models, such as mice and rats, are indispensable equipment in biomedical research. This plays an important part inside the development of medical, veterinary and scientific breakthroughs. They were employed since the beginning of medical discovery and are still contributing considerably until today. However , the main topic of animal study can be highly-charged and differs in different views of individuals. Even so, we simply cannot deny the very fact that animal-based researches have been part of every single medical breakthrough discovery for more than more than 100 years. Through this, there is a quick technological advances and creature studies remains a need for scientific researches today and even in future.

The most frequently used laboratory creature models will be rats and mice. According to the Foundation for Biomedical Analysis (FBR), 95% of all clinical animals are mice and rats. Experts and scientists prefer rats due to its ease since they are small , easily housed and preserved, and they also adjust well to new natural environment. They reproduce quickly and also have a short life time of 2 to 3 years (Melina, 2010), therefore enable analysts to have a number of generations of offspring’s during a reasonable period of time (Johnson, 2012). And also, rats are relatively inexpensive compared to additional animal models and can be bought in large quantities via commercial makers that type rodents specifically for a certain utilization in research. Most mice and rats utilized in a medical trial is of the same stress or particular breed of dog, so that besides sex variations, they are to some extent almost identical genetically. Another reason is that the rodents’ genetic, natural and patterns characteristics carefully resembles those of humans. Jenny Haliski, a representative for the National Commence of Wellness (HIH) Business office of the Laboratory Animal Welfare, once declared “rats and mice happen to be mammals that share a large number of processes with humans and they are appropriate for use for answer various research questions. “

Most the commonly used mice in laboratories happen to be albino. This is due to a common changement in tyrosinase gene. In which tyrosinase is among the key digestive enzymes in mammalian melanin synthesis (Ramsden Riley, 2014). The prevalence of albinism in the laboratory rodents is because many of the earliest proven strains were albino, and also in early times, it is an convenient selection. ICR strain, an albino, is actually a mouse model of Swiss origin and originated from the initial two male and eight female hvidf?dning non-inbred rats (Research Versions and Providers, n. d. ). This kind of outbred pressure was named after the Company of Malignancy Research in the united states. The rats strain includes a docile characteristics, high productivity, rapid growth rate and low incidence of spontaneous tumor.
