The drug problem in The Netherlands

In the Netherlands, the drug problem among adolescents developed as a new phenomenon in the mid 1960s. Without remarkable success, methadone maintenance programs were introduced in 1968. Drug free treatment in therapeutic communities, developed since 1972, was successful after the first experimental years. This success provoked the illusion that drug related problems could be solved by treatment; low threshold programs, putting few demands on participants, were established to dispense methadone. The illusion was that addicts can be motivated into further treatment if they are brought into contact with professionals. As the addict population kept growing and their street crimes increased in number, Dutch drug policies changed in 1978, using methadone as a means to decrease criminal activities rather than to treat addicts. This also turned out to be an illusion. Currently, there is strong political pressure to distribute heroin to addicts to diminish the negative side effects of drug abuse. Dutch drug policies are characterized by the opinion that drug problems cannot be solved and have to be accepted.     

The Selfish Brain And The Barker Hypothesis

1. Brain sparing is a feature of intra-uterine growth retardation (IUGR). This implies that there is a redistribution of metabolic supply so that body growth slows to a greater extent than brain growth. 2. Intra-uterine growth retardation, as evidenced by a low birthweight for gestational age is a predisposing factor for hypertension, cardiovascular disease and diabetes mellitus in adult life. 3. In species like humans, nephrogenesis is complete before birth. In the rat, it is completed shortly after birth. In both species, it can be shown that either undernutrition or IUGR is associated with reduced nephron number. 4. It has been proposed that oligonephropathy results in hyperfiltration, which ultimately leads to glomerulosclerosis and hypertension. The renin-angiotensin system (RAS) is necessary for normal renal development and fetal renal function. In the rat, blockade of the RAS in the first weeks of life by pharmacological agents reduces glomerular number and has been shown to cause hypertension in adult life. Renal denervation reduces the activity of the fetal RAS and also causes abnormal development of the renin-secreting cells. 5. There is tonic renal sympathetic nerve activity in the late gestation fetal sheep. The level of renal sympathetic nerve activity (RSNA) is influenced by the fetal behavioural state. 6. However, interactions between the developing kidney and the developing sympathetic nervous system are poorly understood. On the one hand, renal innervation may be important in the provision of neurotrophic factors that stimulate the development of the RAS and kidney. On the other, high levels of RSNA associated with circulating catecholamines and vasopressin may cause vasoconstriction and limit nephrogenesis. This latter effect could be a predisposing factor to adult hypertension and cardiovascular disease.

论人体生命的三重品格

本文讨论的是人体生命观的问题,从人的本质来看,人体生命与其它生命体有着原则的区别。人体生命是神圣品格、质量品格和价值品格的辩证统一。人体生命三重品格以价值品格为核心,密不可分地联系在一起。片面强调人体生命的质量品格或神圣品格,必然使人们在理论和实践上陷入二难境地。
