fluphenazine enanthate and fluphenazine decanoate: intramuscular injection and esterification as requirements for slow - release characteristics in dogs.14c-fluphenazine base was administered intramuscularly in sesame oil to five male beagles (2 mg/kg). the concentration of radioactivity in plasma and the excretion of radioactivity in urine and feces were measured for 14 days. maximum concentrations of radioactivity were found in plasma 2 hr after administration. these levels declined with elimination half-lives of 3.20 hr during the 2-12-hr interval after dosing and of 4.02 days during the 2-14-day interval. most administered radioactivity was ...1976966144
failure of estradiol benzoate given after birth to prevent the adrenal glands from shrinking in newborn rats.two hr after birth, newborn rats were given a subcutaneous injection of 0.01 mg estradiol benzoate dissolved in 0.05 ml sesame oil. other siblings were given sesame oil alone. autopsy was performed on days 1, 2 and 3 after birth. gravimetric and histologic examinations of the adrenals from these animals and from normal littermate controls were made together with the determination of plasma corticosterone concentrations. in all the three groups of rats, estrogen-treated, oil-treated and non-treat ...19761009895
abolition of the diethylstilbestrol reduction of enzyme leakage from muscle by a 3,3' diallyl substitution.diethylstilbestrol (des) lowers enzyme efflux from isolated mouse skeletal muscle. it also lowers the high serum enzyme activities in duchenne's muscular dystrophy. we have begun a systematic study of des congeners, to identify those portions of the des molecule which are critical to these effects, and to tailor a molecule which might have fewer feminizing effects. the first compound tested was the 3,3' diallyl derivative of des (das). it was selected because previous reports indicated that it w ...1977897342
effects of threonine supplementation on the slope assay for protein quality.several diets considered to be marginally deficient in threonine were fed to young male rats at protein levels ranging from 3 to 9%. protein sources included lactalbumin (reference standard), soy protein with added methionine, pea protein with added methionine, rice-casein, and peanut-sesame-fish. chemical scores and plasma amino acid scores indicated that these diets were limiting in threonine at the 3--4% protein level; increased growth resulted from supplementation with threonine. after threo ...1977924931
[selenium content in the blood cattle from venezuela. i. central and portugueste zones].whole blood concentrations of selenium were determined in 776 dairy cows and calves from 28 farms located in three states (aragua, carabobo and guárico) of the central zone of venezuela and in portuguesa state. selenium levels largely varied according to both the geographic distribution and animals breed. cattle from guárico state showed the lowest average concentration (0.21 ppm) and those from portuguesa the highest one (0.67 ppm). a group of animals from turén (a district of portuguesa state) ...1977931500
influence of fasting on the absorption and effects of delta9-tetrahydrocannabinol after oral administration in sesame oil.tissue levels of 3h were higher 2 hr after oral administration of 3h-delta9-thc (10 mg/kg in sesame oil) to male fischer rats in the morning compared with treatment in the afternoon. a corresponding reduction in potency was seen for the impairing effect of delta9-thc on performance of a conditioned avoidance response (car). the hypothesis that these effects were related to the interval between feeding (which normally occurs during the night in the nocturnal rat) and drug administration was suppo ...1977558623
fertility of norgestomet treated dairy heifers.four studies are described involving 2573 friesian heifers treated with norgestomet and oestradiol valerate to control the ovarian cycle. all treated animals were inseminated at fixed times following treatment. in study 1 insemination 48 and/or 60 hours after treatment resulted in a non-significant greater proportion of heifers becoming pregnant than at 48 x 72 hours. large variations in fertility among farms were recorded in field trials of norgestomet (searle) and oestradiol valerate. in study ...1977878243
morphology, growth characteristics and oestrogen-binding capacity of dmba-induced mammary tumours from ovariectomized rats.the morphology of 20 mammary adenocarcinomas induced by 7,12-dimethylbenz(a)anthracene (dmba) in sprague-dawley rats was compared with their growth characteristics and oestrogen-binding capacity following ovariectomy. the capacity to bind (3h)oestradiol-17b did not appear to be related to the growth characteristics, time of appearance after dmba administration, or time between ovariectomy and assay for specific oestrogen-binding proteins. furthermore, different tumours appeared to have oestrogen ...1977405032
effect of progesterone on the initiation of respiration of the newborn.on the 30th day of pregnancy, the experimental fetuses in 19 rabbits were injected intraperitoneally with 0.1-1.0 mg progesterone (p). the control fetuses in the contralateral uterine horn were treated with the solvent, sesame oil. both the experimental and control fetuses were delivered 10 min after treatment by hysterotomy to measure the p concentration of their lung tissue and observe their respiration during the initial 2 h of postnatal life. in comparison with the controls, the experimental ...1977245313
estrogen receptors in androgen-induced breast tumor regression.the hormone-dependent 7,12-dimethylbenz(a)anthracene rat mammary tumor has been shown to regress when administered pharmacological doses of testosterone propionate. tumor regression was correlated with estrogen receptor before and 15 to 20 days following testosterone therapy. a dramatic decline of receptor occurred in all regressing tumors, whereas those administered sesame oil alone maintained both growth and receptor content. although receptor in regressing tumor was significantly less than in ...1977192456
effects of aldosterone on the urinary excretion of total and non-dialyzable hydroxyproline.in order to explore the role of mineralocorticoids on collagen metabolism, the effects of aldosterone on the urinary excretion of total and non dialyzable hydroxyproline (hypro) was studied in rats. the administration of aldosterone in sesame oil, 75 microgram/100 g body weight to adrenalectomized rats maintained on 1% nacl solution as drinking fluid and 1 mg of cortisone subcutaneously daily, provoked elevation of total and non dialyzable hypro in urine (p less than 0.001), when compared to sim ...1977590925
