Intensive work needs to continue on the genetic characteristics of the X-Y chromosome. There needs to be further clarification of the allele penetrants and the oncogenes, as well as determination of the specific chromosomes. It is now apparent that the neurotransmitters, particularly dopamine, seratonin, and norepinephrine, as related to the MFB receptor sites, are a determining factor in the presence or absence of this disease. However, the exact manner in which these neurotransmitters and receptor sites act, particularly in terms of the feed-back systems, remains obscure. New receptor sites are also being discovered and additional neurotransmitter systems, such as the second messenger system, uncovered. It would be naive at this point to attempt to delineate specific receptor sites or neurotransmitter systems as the absolute determinant of the disease. However, the basic heuristic model accepted by the Georgia Impaired Health Professionals Program remains valid. The heuristic model proposed in the past 15 years remains basically intact and valid. In this model, it is apparent that the essential disease criteria are fulfilled by alcohol and other drug addictions. Chemical dependency is a primary, psychosocial, biogenetic disease. The American culture, however, often fails to appreciate the difference between controlled abusive use and the uncontrolled addictive user. They do not understand that controlled abusive use can lead to severe physical changes, even death.(ABSTRACT TRUNCATED AT 250 WORDS)
需要继续深入研究X - Y染色体的遗传特征。需要进一步阐明等位基因外显率和癌基因,以及确定具体的染色体。现在很明显,与中脑边缘叶多巴胺系统(MFB)受体位点相关的神经递质,特别是多巴胺、血清素和去甲肾上腺素,是这种疾病存在与否的决定性因素。然而,这些神经递质和受体位点的确切作用方式,尤其是在反馈系统方面,仍然不清楚。新的受体位点也在不断被发现,其他神经递质系统,如第二信使系统,也被揭示出来。在这一点上,试图将特定的受体位点或神经递质系统描绘成该疾病的绝对决定因素是天真的。然而,佐治亚州健康受损专业人员项目所接受的基本启发式模型仍然有效。过去15年提出的启发式模型基本保持完整且有效。在这个模型中,很明显酒精和其他药物成瘾符合基本的疾病标准。化学依赖是一种主要的、社会心理性的、生物遗传性疾病。然而,美国文化常常未能认识到有节制的滥用和无节制的成瘾性使用之间的区别。他们不明白有节制的滥用也会导致严重的身体变化,甚至死亡。(摘要截选至250字)
