| dopamine-mediated behavior produced by the enkephalin analogue fk 33-824. | intraperitoneal injection of fk 33-824 produced apomorphine-like stereotyped behavior in rats. antagonism of this stereotypy by naloxone and neuroleptics suggests that fk 33-824 can activate opiate and dopamine receptors in the brain. because increased dopaminergic neuronal activity is thought to be involved in schizophrenia and dopamine-mediated stereotypy has been used as an animal model for this illness, these results are consistent with an involvement of endogenous opiate-like peptides in sc ... | 1979 | 233159 |
| prevention of reactivated herpes simplex infection by human leukocyte interferon after operation on the trigeminal root. | microneurosurgical procedures on the trigeminal-nerve root are often followed by reactivation of herpes simplex virus infection, manifested by herpes labialis or oropharyngeal herpesvirus shedding or both. in a double-blind study of the ability of human leukocyte interferon to prevent this reactivation, patients with a history of herpes labialis were given 7 x 10(4) u of interferon per kilogram of body weight per day or placebo for five days beginning on the day before operation. in 18 patients ... | 1979 | 221812 |
| in vitro model simulating the form of exposure of bacteria to antimicrobial drugs encountered in infection. | a new model, which is designed to investigate the in vitro activity of antibiotics as a function of different concentration-time curves, is described. the antibiotic is allowed to diffuse through a membrane into a bacterial culture until a peak level is reached; the antibiotic is then removed by flow-assisted back diffusion. with this arrangement it is possible to expose bacteria to a changing concentration of drug while maintaining a constant volume of bacterial culture. preliminary studies wer ... | 1979 | 383014 |
| interactions of surface-active alkyltrimethylammonium salts with the plasma membrane of acanthamoeba castellanii. | the interactions of three surface-active alkyltrimethylammonium salts (c12-c16) with the plasma membrane of acanthamoeba castellanii were studied. the surfactants caused a release of k+ from the cells at premicellar concentrations. the lytic effectiveness of the surfactants increased with an increase in the length of the alkyl chain with about an order of magnitude for every two carbon atoms added to the alkyl chain. binding studies with the c16 homologue revealed that at a concentration corresp ... | 1979 | 433611 |

| hepatocellular carcinoma in the u.s.a., etiologic considerations. localization of hepatitis b antigens. | the serologic and tissue markers of hepatitis b virus (hbv) were studied in 50 patients in whom hepatocellular carcinoma (hcc) was confirmed at autopsy. serologic and tissue markers included serum hepatitis b surface antigen (hbsag), tissue hbsag, tissue hepatitis core antigen (hbcag), and serum antibody to hbcag (anti-hbc). twenty-two patients had hcc arising in alcoholic cirrhosis; 2 of the 22 (9.1%) had one or more of the hbv tissue and serologic markers. this infection rate is similar to the ... | 1979 | 215488 |
| dnag (primase)-dependent origins of dna replication. nucleotide sequences of the negative strand initiation sites of bacteriophages st-1, phi k, and alpha 3. | the simplest known origins of dna replication occur in the single-stranded bacteriophages. in one set of phages, negative strand synthesis is initiated by a single protein, the product of the escherichia coli replication gene dnag. evidently, in these phages--g4, st-1, phi k, and alpha 3--the origin for negative strand synthesis consists of a nucleic acid element capable of direct recognition by the dnag priming protein. we have located and sequenced the origins of negative strand synthesis in s ... | 1979 | 387790 |

| hypolipidemic effects in dogs of ml-236b, a competitive inhibitor of 3-hydroxy-3-methylglutaryl coenzyme a reductase. | ml-236b, a competitive inhibitor of 3-hydroxy-3-methylglutaryl-coa reductase, significantly reduced both serum cholesterol and phospholipid levels in dogs, when used at a dosage higher than 10 mg/kg per day. triglyceride levels were not consistently changed, but beta- and pre-beta-lipoproteins were preferentially reduced. serum cholesterol levels were reduced by 44--45% at the higher dosage of 100--400 mg/kg per day (for 5 weeks) but ml-236b caused no significant changes in the cholesterol conte ... | 1979 | 223590 |

| the role of hormones in the etiology of breast and endometrial cancer. | despite many years of extensive investigation, there has been neither a clear-cut pattern of hormonal production nor milieu found in women with breast cancer. estrogen replacement therapy for menopause does not significantly increase the risk of breast cancer and one study indicated that estrogen users have a lower incidence of breast cancer than that observed in untreated women. some studies have shown that the mortality rate from breast cancer is lower in estrogen-treated postmenopausal women. ... | 1980 | 294115 |

| kinetic investigations of the autoxidation of adrenalin. | generation rates of superoxide anions (o2-) by autoxidizing adrenalin at ph 9.5 were determined in solutions containing either superoxide dismutase (0.85 m-1 s-1) or hydroxylamine (0.0185 m-1 s-1) as competitive scavengers. the rate constants of o2- with adrenalin and hydroxylamine were calculated for neutral and alkaline solutions. the respective values were for adrenalin: 5.6 x 10(4) m-1 s-1, ph 7.8; 7.0 x 10(3) m-1 s-1, ph 9.5--and for hydroxylamine 5.9 x 10(4) m-1 s-1, ph 7.8; 3.4 x 10(4) m- ... | 1981 | 217185 |
| adrenocortical function, electrolyte metabolism, and blood pressure during prolonged adrenocorticotropin infusion in juvenile hypertension. | the effect of a continuous 5-day acth infusion (40 u/24 h) on adrenocorticoid function, electrolyte metabolism, and blood pressure was investigated in eight normotensive children and eight patients with hypertension of unknown origin. there was a continuous rise of plasma cortisol and deoxycorticosterone in all patients. plasma aldosterone rose transiently in the normotensive and the hypertensive group. a transient kaliuresis and a continuous fall in serum k+ were observed in all patients. acth ... | 1982 | 221530 |
| effects of the intravenous administration of calcium on nephrogenous cyclic amp: use as a parathyroid suppression test. | the question of parathyroid autonomy in primary hyperparathyroidism has been the subject of conflicting immunoassay data. we studied the effects of calcium infusion (12 mg/kg/3h) and calcium injection (3 mg/kg/10 min) on peripheral plasma parathyroid hormone (ipth) determined with a multivalent antiserum and on the excretion of nephrogenous cyclic amp in normal subjects and in 7 patients with primary hyperparathyroidism who displayed only mild, intermittent hypercalcemia. in control subjects, ca ... | 1982 | 221521 |
