the stimulatory effect of 5ht and the role of the paraventricular nucleus on pms induced ovulation in the immature rat.	immature rats can be induced to ovulate with pregnant mare serum (pms) as long as they weigh over 60 g. in the rats weighing less than 60 g 5-hydroxytryptamine (5ht)-60 micrograms/rat intraventricularly or 2 micrograms/rat in the paraventricular nucleus (pvn)-stimulated ovulation. injections into several other hypothalamic nuclei were ineffective. in rats weighing greater than 60 g, lesions of the pvn or injection of 10 micrograms/rat p-chlorophenylalanine into the pvn inhibited ovulation. the h ...	1979	37456
sickled erythrocytes, hyphema, and secondary glaucoma: vi. the relationship between intracameral blood cells and aqueous humor ph, po2, and pco2.	injection of hgb sc blood into rabbit anterior chambers resulted in lowering of aqueous humor ph and po2 and elevation of aqueous humor pco2. these effects appear to contribute to the sickling of erythrocytes that occurs in aqueous humor.	1979	37471
alterations in creatinine clearance during respiratory distress syndrome.	some renal parameters have been studied in newborns with respiratory distress syndrome (rds). during the first 24 h, the serum creatinine level of the severe cases of rds are significantly increased, decreasing gradually with improvement of the rds and reaching normal values within 10 days. blood urea nitrogen remained unchanged. in the milder cases of rds, the serum creatinine also showed a slighter increase, which became normal within 4 days after birth. during the acute phase of rds, there is ...	1996	38862

the effect of oral pancreatic extract on jejunal bactericidal activity in protein-deficient vervet monkeys challenged with vibrio cholerae.	eleven vervet monkeys (cercopithecus aethiops) were fed with an "o" protein diet. after the serum albumin level fell below 2.5 g/100 ml the animals and 4 controls, which received regular monkey chow, were orally infected with a monkey-adapted strain of vibrio cholerae. the total bactericidal activity of the jejunal fluid decreased during feeding with "o" protein diet, but increased after challenge with v. cholerae in all groups. the non-immunoglobulin-bound bactericidal activity, which also decr ...	1979	41422
effect of intra-arterial injection of crude cholera enterotoxin on canine small bowel.	injection of a crude preparation of cholera enterotoxin into the superior mesenteric artery caused isotonic fluid secretion by the canine small bowel. in dogs previously exposed to cellular antigens of vibrio cholerae, the time course of the intestinal response to intra-arterial injection of crude enterotoxin was similar to that observed after intraluminal exterotoxin challenge.	1979	41424
biochemical mechanism of nitrofurantoin resistance in vibrio el tor.	vibrio el tor cells contain a constitutive reductase enzyme which converts nitrofurantoin to an active principle that is responsible for the observed antibacterial activity of the drug. acquisition of resistance of this strain towards nitrofurantoin is associated with the loss of this reductase. this enzyme is located in the periplasmic region of the nitrofurantoin-sensitive cells, and seems to play an important role in transporting the drug into the cells.	1979	41800

new approach to management of intracranial aneurysms.	in six cases an attempt was made to relieve the tension on intracranial aneurysms by temporarily clamping the internal carotid artery in the neck, so as to increase the expansibility of the artery. this approach was based on the concept (or "a principle") that haemorrhage is caused by the aneurysm having to bear the full force of systolic pulse pressure when atherosclerosis prevents this pressure being taken up by the normally expansile arterial wall. follow-up has been fairly short, but the pre ...	1993	46379
post-jejunoileal-bypass hepatic disease. its similarity to alcoholic hepatic disease.	the authors studied serial hepatic biopsies of five patients who developed hepatic failure following jejunoileal bypass for extreme obesity, with autopsies of two. the hepatic histologic changes included centrilobular or focal alcoholic hyalin, intrasinusoidal collagenosis, fatty hydropic degeneration, and neutrophilic infiltrate. at least two of the patients were abstinent from alcohol, both prior to and after the surgical procedures. the others, after the bypass procedures, had reduced alcohol ...	1993	46697
immunofluorescent studies on antibodies directed to a buried membrane structure present in lymphocytes and erythrocytes.	brief digestion of human peripheral blood lymphocytes by vibrio cholera neuraminidase (vcn) revealed hidden components of the membrane. autologous human serums contained antibodies directed to these components that were readily demonstrated by immunofluorescence. antibodies of similar specificity were found in all normal serums. the antibodies were principally of the igm variety with lesser amounts of the igg class present. they were equally active at 4 degrees c and 37 degrees c. the vcn reveal ...	1975	46880

demonstration of shared and unique immunological determinants in enterotoxins from vibrio cholerae and escherichia coli.	immunodiffusion and biological neutralization studies demonstrated that the heat-labile enterotoxin (lt) from escherichia coli has antigenic determinants in common with each of the isolated subunits (a and b) of the enterotoxin (choleragen) from vibrio cholerae. each of the enterotoxins also possesses unique antigenic specificities. monospecific antiserum to lt was prepared by immunization with antigens derived by immune precipitation of e. coli cell-free supernatant with isolated specific antic ...	1978	83301
