I955 The author wishes to express his sincere appreciation to Dr R. E. Hungate for an introduction to the fascinating cattle protozoa and for many stimulating discussions during the course of the experiments. The investigation was supported in part by funds for biological and medical research by the State of Washington, initiative measure number 171. In clinical work, where general electrolyte ...

It is well established that many antidepressant compounds with proven clinical efficacy act on the serotonergic and noradrenergic pathways. The monoaminergic hypothesis of major depression (MD) stipulates that a deficit in brain monoaminergic neurotransmission in various brain areas including the frontal cortex, hippocampus, amygdala or hypothalamus would account for some of signs and symptoms ...

Steindler and Luck (1938) noted that localised lesions in the territory of the posterior primary divisions of the spinal nerves were capable of causing pain which radiated not only in this region but also in that of the anterior primary divisions. Kellgmen (1939) and Lewis and Kellgren (1939) injected hypertonic saline in the mid-line of the back and caused pain of segmental distribution which ...

Since the discovery by Dicke (1950) that remarkable benefit followed the withdrawal of wheat and rye from the diet of the coeliac child, much work has been done on the significance of these and other foodstuffs in the coeliac syndrome. Few of these studies, however, involved oats, a food containing a prolamin similar to the gliadin of wheat which was proved to be injurious by van de Kamer, Weij...

The importance of a study of the ovine fatty liver arises from the frequent reports of this condition in cases of pregnancy toxaemia occurring in the field or induced experimentally (Roderick & Harshfield, 1932 ; Frazer, Godden, Snook & Thomson, 1938-9, 1939-40; Groenewald, Graf, Bekker, Malan & Clark, 1941 ; Underwood, curnow & Shier, 1943). According to Best & Ridout (1933, 1936), Best (1934)...

The unequivocal incorporation of radioactive phosphate (32p) into the nucleic acids of brain slices has not as yet been demonstrated. Because of the great interest in the nucleic acids of the nervous system aroused by the work of Caspersson (1947) and Hyden (1943, 1947), it was decided to investigate the possible incorporation of 32p into the pentosenucleic acid (PNA) and deoxypentosenucleic ac...

SUMMARY A further instance of the successful removal of a phaeochromocytoma is reported and it is suggested that halothane, despite theoretical contraindications, may be the anaesthetic agent of choice for this procedure. The possible value of (a) prolonged pre-operative preparation with either oral phentolamine or phenoxybenzamine with or without pronethalol, (b) pre-operative blood volume stu...

Accurate measurement of returns to education is particularly important in African countries where government resources are extremely limited, and education's competition for budget dollars is intense. This paper attempts to measure consistently the returns to education in Ghana. The chief problem to be handled in the measurement of returns to education in Mincerbased wage regressions is ability...

Social Capital theory has tended to treat social cohesion as a mere aggregation of individual and community level characteristics, ignoring the long tradition of theory on social solidarity and social cohesion at the societal level. However, the key indicators of social capital – associational membership and social trust – do not co-vary cross nationally and societies rich in community level so...
