Summary
Chronic granulomatous disease is a ‘phagocytic disorder that is rare and genetically inherited, and it entails deterioration of the immune system, thus making the affected population vulnerable to various infections caused by bacteria and fungi (Kepenekli 2014: 1)…

Download file to see previous pages ests that the disease is present in ‘one in 250,000’ infants at birth, but the symptoms become evident only when the child reaches a few months of age (Assari 2006: 6). Only 21% of patients have survived the disease beyond the age of 7 previously, whereas the recent trends show improvement in the survival rates because of the ‘advancement in treatments’ (Assari 2006: 6). On the other hand, the disease can rarely occur in adults, and therefore, if someone has the problem of ‘recurrent infections’, it will be advisable to subject such individuals to an evaluation, irrespective of the age factor (Chung, Cyr & Ellis 2013: 2).
Gene therapy, which is the intervention in a disease or disorder through introducing genes into the affected cells to set right the impacts of ‘specific gene mutations’, is one of the methods used in the treatment of CGD (Dugal & Chaudhary 2012: 4). However, evidence suggests that in order for the treatment to be effective, the appropriate gene will have to be incorporated into the target cell ‘specifically, efficiently and stably’ (Dugal & Chaudhary 2012: 4). On the other hand, it is also necessary to use the most appropriate vector for the introduction of the gene or gene delivery into the human cell. Research studies have identified lentiviral vectors (LVs) to be one of the effective and the ‘most widely used’ vectors in gene therapy (Dugal & Chaudhary 2012: 4). A study conducted by Assari (2006: 6) on mice found that gene therapy, using recombinant retroviral vectors, is an effective treatment for the reconstruction of normal neutrophils and in building ‘resistance to pathogens’ such as Aspergillus. The author also contends that gene therapy, using retroviral vectors in two humans, has produced ‘encouraging results’ where both of them have attained remarkable levels of gene corrected cells and their clinical conditions show good improvement (Assari 2006: 6). Studies further substantiate the fact that gene ...Download file to see next pagesRead More

Is Gene Therapy Permissable
Gene therapy is a methodology devised to rectify the defective gene by exploiting gene itself as a medicine. Gene therapy encompasses transmitting a therapeutic gene into explicit cells to substitute a defective gene. The process allows physicians to cure and provide remedies to those diseases which are otherwise incurable through drugs and surgery.

Gene therapy
The genes thus introduced exert their benefits by either compensating for the abnormal genes or by producing beneficial protein or by supplementing the abnormal gene (Hecht, 2004). The first gene therapy clinical trial started in 1990 (Verma and Weitzman, 2005).

Gene therapy
This process is termed gene therapy. The field of gene therapy has been researched for decades and is continually being developed. Almost all diseases have a genetic component and by correcting the genetic code, the rules of the game can be changed. Though scientists are still figuring out the intricacies of gene therapy, and there is much room left for improvement, once gene therapy is mastered it could revolutionize the world by saving or increasing the quality of many lives.

Effectiveness of maggot therapy for chronic wounds
Maggot therapy is not new in medicine and even during the World War I Dr. Baer observed soldiers left wounded for days on the battleground but having the clean and healing wounds because they were infested with maggots. This observation has led to the number of clinical studies which proved the unique effectiveness of maggots on chronic wound healing.
