[some aspects relating to the aflatoxin generation during the self-heating of cereals].in a stored batch of grain which was already affected by mould-formation tests were carried out with the known aflatoxin producer aspergillus flavus. a significantly lower aflatoxin production ensued if the mould growth was not connected with self-heating of the stored product. however, in conformity with increasing mould formation the germinating power was adversely affected and the significant signs (fatty acid number, reductive and none-reductive sugars) were influenced in the grain, irreleve ...197898933

improved safety of splenoportography by plugging of the needle tract.splenoportography, a useful preoperative diagnostic procedure in patients with portal hypertension, has been largely discontinued because of the risk of hemorrhage. we have used both ivalon and gelfoam in particle and plug form to plug the needle tract after splenoportography. initial studies were conducted on six dogs. plugging of the needle tract by injection of suspensions of small gelfoam or ivalon particles resulted in intravasation of these particles into the splenic vein. this was demonst ...197898987
microradiographic demonstration of pyelolymphatic backflow in the porcine kidney.pyelolymphatic backflow occurs when intrapelvic pressure rises acutely. although peripelvic and hilar lymphatics have occasionally been demonstrated during intravenous urography and retrograde pyelography, the patterns of intrarenal microlymphatic filling have not previously been studied radiographically in multipapillary kidneys. microradiography was performed after retrograde ureteral injections of barium sulfate suspension in recently excised pig kidneys. contrast filled the ducts of bellini ...197898998
jaundice and breast-feeding among alaskan eskimo newborns.the course, incidence, and severity of neonatal jaundice was studied in 95 alaskan eskimo infants. breast-fed infants had higher bilirubin concentrations than bottle-fed babies. both groups experienced high bilirubin levels, similar to those previously reported in navajo and oriental infants but greater than those observed in whites and blacks. a marked capacity to inhibit hepatic glucuronyl transferase was observed in breast-milk specimens but only partly accounted for the bilirubin differences ...197899026
interferon inducing activity of polyinosinic acid.although poly(i) is generally considered to be inactive as an interferon inducer, we have found several authentic poly(i) preparations to be effective inducers. their interferon inducing ability varied considerably from one cell system to another. in human diploid fibroblasts, primed with interferon and superinduced by cycloheximide and actinomycin d, all active poly(i) samples proved nearly as effective in inducing interferon as poly(i).poly(c). in primary rabbit kidney cell cultures, the activ ...197899486

review of laxative utilization in a skilled nursing facility.laxatives are the most frequently prescribed drugs in long-term care facilities. of all nursing home patients, 58 percent receive laxatives--often more than one, and usually on a "prn" basis. this pattern of dosage is probably used in an effort to prevent constipation. selection of a laxative should be based on careful evaluation of the cause of constipation, with due consideration being given to differences in drug effectiveness and the incidence of side effects. a review of laxative utilizatio ...2000101574

morphologic effects of thio-tepa on mammalian urothelium. changes in abnormal cells.morphologic changes induced by thio-tepa were examined in animals with chemically induced neoplasms. both toxic and metabolic effects were documented. degeneration, vacuolization and increased exfoliation (toxic) were most prominent, occurred within 48 hours of exposure, and tended to subside after removal of the drug. nuclear changes (metabolic) were rare and occurred late. neither toxic nor metabolic effects were specific for thio-tepa: both could be detected in control animals receiving salin ...1998104512
shigellosis and escherichia coli diarrhea: relative importance of invasive and toxigenic mechanisms.shigellae and dysentery-like escherichia coli must invade the epithelium of the colon to cause disease which can present as dysentery, diarrhea, or both. this paper addresses the possible role of a shigella dysenteriae-like (shiga-like) toxin in the pathogenesis of shigellosis and e. coli diarrheal diseases. the possibility for such a role is suggested by the following observations: 1) diarrhea, considered to be a result of secretion of water by the small bowel, is frequently observed in shigell ...1979104615

the role of catecholamines in clinical medicine.the sympathetic nervous system is of major importance for the regulation of several physiological functions. drugs which inhibit the actions of catecholamines and adrenergic drugs are used in the treatment of many clinical disorders. the potential role of catecholamines in a number of human diseases has, however, until recent years been studied to a limited extent only due to lack of methods for quantitation of sympathetic nervous activity. after the development of enzymatic isotope-derivative a ...1979106629
baroreceptor control of atrioventricular conduction in man.although human baroreflexes are known to exert a powerful physiological control on heart rate, little information exists on the physiological control they exert on the atrioventricular conduction system. in 11 normotensive subjects with normal atrioventricular conduction, we altered baroreceptor activity by injection of pressor and depressor drugs (phenylephrine and trinitroglycerin) and recorded mean arterial pressure (map, catheter measurements), r-r interval, and pre-his and post-his interval ...1979106985
