Product formulation of phenylbutazone, theophylline, tolbutamide and pharmacokinetics-toxicities of theophylline injections in pigs

Creator:: Suvanakoot, Uthai
Abstract:: A two-part study was conducted with three poorly water soluble drugs (phenylbutazone, tolbutamide, theophylline) to develop two new drug delivery systems based on physical-chemical approaches. In the first part, tolbutamide and phenylbutazone were made into solid dispersions with various excipients using a lyophilization technique. In vitro dissolution studies of these...

Adenosine receptor modulation of seizure susceptibility in rats

Creator:: Szot, Patricia
Abstract:: Adenosine is considered to be a neuromodulator or cotransmitter in the periphery and CNS. This neuromodulatory action of adenosine may be observed as an anticonvulsant effect. Dose-response curves for R-phenylisopropyladenosine (PIA), cyclohexyladenosine (CHA), 2-chloroadenosine (2-ClAdo), Nethylcarboxamidoadenosine (NECA) and S-PIA were generated against PTZ seizure thresholds in the rat. The rank...

Hemoglobin adducts of the organophosphate insecticide azinphos-methyl

Creator:: Bailey, Bonnie J.
Abstract:: Reported here is an investigation to determine if azinphos-methyl (AZM), an organophosphate insecticide, adducts to hemoglobin, and if so, whether the hemoglobin adduct could be used as a quantitative marker of occupational AZM exposure. We hypothesized that AZM, or a metabolite of AZM, binds to hemoglobin in erythrocytes forming an...

Indole-3-carbinol and 3,3'-diindolylmethane : relative potency as modulators of drug metabolism and carcinogenesis

Creator:: Katchamart, Sirinmas
Abstract:: Indole-3-carbinol (I3C), the most abundant metabolite of glucobrassicins, is found in cruciferous vegetables such as broccoli, Brussels sprouts, cabbage and cauliflower. I3C has been shown to have anticarcinogenic activity against many chemical carcinogens in multiple target organs in animal models. However, the anticarcinogenic activity of I3C is considered indirect since...

Certain physiological and pharmacological effects of radiation on rabbits

Creator:: Wagelie, Edwin Gan
Abstract:: Data were taken, following irradiation exposure to 100r and 300r cumulative dose, on 89 rabbits of three breeds that vary greatly in body size. Hematological, intestinal motility, and ear vascularity examinations were performed. Least square estimates have been obtained and an analysis of variance has been conducted in order estimate...

A metabolic function of selenium, assessed with rat liver homogenates

Creator:: Bull, Richard Charles
Abstract:: In three separate trials rats were fed either a basal diet deficient in selenium and vitamin E or the same diet supplemented with one or both of these factors. In addition to these treatments in two of the trials, ethoxyquin was included to provide adequate lipid antioxidant protection and to...

Effects of radiation on selection progress in mice

Creator:: Womack, James Ernest
Abstract:: The effects of x-irradiation on quantitative genetic traits was investigated by comparing the response of irradiated mice to selection for litter size and 28-day weight with the response to selection for the same two traits in non-irradiated lines. Irradiated lines were maintained at three levels of x-irradiation, 25 r, 50...

Manganese absorption by barley roots

Creator:: Maas, E. V. (Eugene Vernon), 1936-
Abstract:: An investigation of Mn uptake by five-day-old excised barley roots revealed that a metabolically-mediated process was involved. In short-term experiments, the rate of Mn absorption was comparable to that of the macronutrient cations. Like other metabolically absorbed cations, the Mn absorption rate was a direct function of the ambient concentration...
