Iris nodules in essential iris atrophy. | Seven cases are reported, believed to be the first in the literature, in which iris nodules are verified in the complete spectrum of essential iris atrophies. This feature appears late in the course of the disease as small yellow nodules that progressively increase in number and gradually become dark brown. The differe... | 818,989 | [

Effects of intravenous nitroglycerin on left ventricular function and ST segment changes in acute myocardial infarction. | It has been shown previously that 30-minute infusions of intravenous nitroglycerin in patients with acute myocardial infarction are able to lower left ventricular filling pressure and improve left ventricular function while lowering mean arterial pressure by only 7 mmHg (0.9 kPa). A decrease in sigmaST in praecordial S... | 819,021 | [

Some problems of host and parasite interactions in the coccidia. | The current status of some concepts of host and parasite interactions in the coccidia are discussed and evaluated. It is suggested that winter coccidiosis of cattle caused by Eimeria zuernii results from activation of arrested endogenous stages in the tissues of the host. A second aspect of clinical coccidiosis is that... | 819,648 | [

Leucocyte values of alpha-L-iduronidase activity in mucopolysaccharidosis I. | Assay of alpha-L-iduronidase in peripheral leucocytes is a rapid and simple diagnostic aid in mucopolysaccharidosis I. The mean value for heterozygotes is one-half the value of normal controls, but overlap between the two groups occurs. Use of this assay may be helpful in genetic counselling of selected couples. | 819,651 | [

Reaction of dihydrofolate reductase with dansyl chloride. Chemical modification of a sensitive lysine residue and fluorometric studies of the dansylated enzyme. | Dihydrofolate reductase from amethopterin-resistant Lactobacillus casei is virtually completely and irreversibly inactivated by relatively low concentrations of dansyl chloride. The complete inactivation can be correlated with the dansylation of a single lysine residue and ca. 90% quenching of protein fluorescence. Thi... | 820,367 | [
