Basic principles of cellular organization.

The hypothesis is put forward that the division of the animal body into three germ layers represents not only histological, but also functional specialization, the ectoderm taking over functions through which the animal is in contact with, acted upon or reacts to the external world, the entoderm metabolism and the mesoderm architectural and mechanical organization. This is assumed to mean that the tasks of life have been divided into three large function domains at an early stage of multicellular evolution, each germ layer taking over one domain and developing largely independently of the other two in the further course of phylogeny. The germ layers are autonomous in their own spheres, giving the body, in effect, a tripartite government. The potentiality of conceptual thought is inherent in all germ layers, reaching a high state of development in the entoderm and mesoderm at a much earlier stage of development than in the ectoderm. The animal body, as a whole, is in control of all its biologic activities; it is a self-designing, self-developing and self-perpetuating entity. The control of cellular organization is a mesodermal task.

The therapeutic effect of hemodialysis on schizophrenia: comments and further possibilities.

Intermittent hemodialysis was recently found to have a therapeutic effect on schizophrenia, pointing to biochemical disturbances and possibly to renal malfunction as the cause of some forms of mental disorder. This paper points out that intermittent hemodialysis is not equally effective for the elimination of all solutes in the plasma. It can dispose of significant quantities of substances for which the normal urine/plasma concentration ratio is small, not of substances which the kidney concentrates in the urine by a large factor. It is further pointed out that for substances with a small urine/plasma concentration ratio thermogenic sweating could also constitute an effective means of disposal and its use is suggested as possible alternative to hemodialysis.

Surfactants and atherogenesis.

In previous publications (1,2) the hypothesis was put forward that atheroma is caused by some pathogen or metabolic fault which impairs the transportability of cholesterol in the plasma. The lipoproteins containing the faulty metabolites are assumed to be incapable of traversing the capillary endothelium and continue to circulate uselessly in the blood stream, possibly giving rise to hypercholesterolaemia, until captured by lipophages which, if they can successfully complete their journey, void them into the gall bladder. The present paper takes the argument a step further by pointing out that the types of substances most likely to cause the described impairment are surfactants. A surfactant finding its way into the plasma could separate cholesterol from its carrier protein and itself become its carrier. The complex would still be kept in suspension in the plasma, but unable to cross biological barriers like the capillary endothelium. An important argument in favour of the hypothesis is that it can offer an explanation of the long-standing medical mystery of the connection between atheroma and the hardness or softness of the water supply. Infant deaths from coronary occlusion present a similar enigma. The paper points out that surfactants can conceivably find their way into infants' feeding bottles.

The recession of gastric cancer and its possible causes.

The paper re-examines the hypothesis that excessively hot drinks constitute an important risk factor in the causation of gastric cancer. The recession of gastric cancer mortality rates in the United States in recent decades is attributed to dietary changes tending to supplant the traditional hot beverages. One such change was the appearance of domestic refrigerators, promoting iced drinks, another the popularisation of soft drinks. The example of Okinawa is quoted where in 1972, after 27 years of American administration, gastric cancer mortality rate was 11.3 per 100,000, in contrast to Japan's 46.7, presumably due to the introduction of American dietary habits. While in most Western European countries gastric cancer risk decreased in the last decades, there was little change in Eastern Europe, and rates were rising in some countries, like Portugal, Mexico and Hong-Kong. This is attributed to the increasing pollution of water, promoting its boiling and flovouring. In some countries water is disinfected by chlorination in which case boiling and flavouring may be used to mask the unpleasant smell and taste of disinfectant.

Why hospice day care?

Hospice day care would have to be flexible in order to meet individual needs. It would offer security, warmth and tender loving care, providing an opportunity for patients to socialize and maintain their quality of life. Hopefully day care would provide earlier hospice admissions--extending the continuity of care. Recently the hospice day care standards developed in Michigan were published in the American Journal of Hospice Care. They were developed to provide guidelines for policies and procedures which would assure a quality program. The future of hospice day care depends on further development and implementation of these beginning standards.
