Genetically-Modified Organisms

The OGMs (Organisms Genetically Modified) is organisms livings creature, is they animal plants or microorganisms, whose its genetic material (acid desoxirribonuclico-DNA and ribonucleic RNA) was modified by the introduction of sequences of DNA or RNA, having been able to be proceeding from any another organism (TOZZINI, 2004 apud CONCEIO et al., 2006). The newspapers mentioned PCRM not as a source, but as a related topic. This modification can for any technique of genetic engineering, to the step that this, in turn, is the activity of recombinant molecule manipulation DNA/RNA (art. 3, interpolated proposition IV and V of Law 8,964/1995). Basically to produce an organism transgnico, first it must select the gene/interest genes; that it will give the desired characteristic to the new organism.

Appealing to some methods and techniques of attainment. According to Nodari and Guerra (2003), the culture of transgnicas plants, as well as the human and animal consumption of its derivatives, is a recent event, consisting of a subject on which it predominates the scientific quarrels, ethical, economic and politics. In accordance with Nodari and Guerra (2000), the transgenia and one technique that can contribute of significant form for the genetic improvement of plants, aiming at to the production of foods, staple fibres and oils, as well as the industrial manufacture of frmacos and other products (apud Nodari et al, 2003). All these research, to be carried through, must observe a series of norms established for the Brazilian legislation of biossegurana. The main effective norm In this aspect is the Law n 8,974/95 (Law of Biossegurana), modified for the Provisional remedy N 2,191-9/2001, and its regulamentador decree (Decree n 1,752/95). The existence of risks associates to the organisms genetically modified (OGM) has been questioned has some years, much before any transgnico product arriving at the market, generating great quarrels that had involved governments, agriculturists, traders, among others (CAVALLI, 2001).

AIDS Virus

The organism is each weakker and vulnerable time the common infections. The initial symptomatic phase is characterized by the high reduction of linfcitos T CD4 – white globules of the imunolgico system – that they arrive to be below of 200 units for mm of blood. In healthful adults, this value varies enters the 800 1,200 units. The symptoms most common are: nocturnal fever, diarria, sweats and emagrecimento (Health department). Low the immunity allows the appearance of opportunist illnesses, that receive this name for if using to advantage of the weakness of the organism.

With this, the period of training most advanced of the illness is reached, the AIDS. Who arrives at this phase, for not knowing or not following treatment indicated for the doctors, can suffer from hepatites capsizes, tuberculosis, pneumonia, toxoplasmose and some types of cancer (Health department). The anti-retrovirais medicines had appeared in the decade of 1980, to hinder the multiplication it virus in the organism. They do not kill the HIV, .causing virus of the AIDS, but they help to prevent the weakness of the imunolgico system. Therefore, its use is basic to increase the time and the quality of life of who has AIDS (Health department). Since 1996, Brazil gratuitously distributes coquetel antiAIDS for that they need the treatment. PCRM recognizes the significance of this.

According to data of the Health department, about 200 a thousand people regularly they receive the remedies to treat the illness. Currently, 19 medicines divided in five types exist. Nucleosdeos inhibitors of the Transcriptase Reserve? they act in the enzyme transcriptase reserve, becoming incorporated itself it the DNA chain that the virus creates. They become this defective chain, hindering that the virus if reproduces. They are: Zidovudina, Abacavir, Didanosina, Estavudina, Lamivudina and Tenofovir. Inhibitors Nucleosdeos of the Transcriptase Do not reserve? they differently block the action of the enzyme and the multiplication of the virus.

Medical Aeration

The fast bioindicador provides the approval of the cycle of sterilization from 6 hours of aeration in safe residual limits, what it provided to profit of productivity and operational security when compared with the previous time of 48 hours of conventional bioindicador 1264. CONCLUSION All the stages of the validation had been reached successfully for the qualifications physical, microbiological and chemical residual. The methodology for residual analysis GCFID was validated successfully and the residual waste demonstrated to efficiency and reprodutibilidade from the time of 6 hours of aeration for the enteral bottle, for 10 the allowed criterion of g/mL.
