The Effect of Carbon Monoxide on the Growth of an Aquatic Streptomycete

The Effect of Carbon Monoxide on the Growth of an Aquatic Streptomycete

Date: August 1966
Creator: Francisco, Donald Edward
Description: The major purpose of this investigation was to determine the effect of carbon monoxide on the development of various morphological phases of a single isolate of the aquatic streptomycetes and to elucidate the physiological differences between terminal respiration in the primary and secondary stages. A secondary purpose was to repeat the work of Michael Lee Higgins involving the effect of anaerobiosis on the growth of the organism.

Effect of Colchicine on Neuronal Excitabilty

Effect of Colchicine on Neuronal Excitabilty

Date: August 1978
Creator: Okafo, Ngozi
Description: The abundance of microtubules in receptive dendrites suggests they may function in sensory transduction. Responses of frog muscle spindle receptors and joint receptors is inhibited within 25 minutes by 50 mM colchicine, a microtubuledisrupting agent. The inhibition is reversible upon removal of colchicine, and the time course of recovery is comparable to that of inhibition. Frog olfactory responses are briefly inhibited by washing the olfactory mucosa with perfusion fluid. Colchicine accentuates the inhibition and substantially retards the rate of recovery in a dose-dependent fashion. Colchicine does not affect axonal conduction, nor the oxygen uptake of isolated crab or frog leg nerves. The inhibitory action of colchicine is therefore an effect on the electrical excitability of the receptive dendrites or soma, and not an effect on axonal conduction.

Effect of Cortisone Injections on Complement Titers of Guinea Pigs

Effect of Cortisone Injections on Complement Titers of Guinea Pigs

Date: 1958
Creator: Renshaw, Larry Alan
Description: As complement is now believed to have some function in immunity it becomes of interest to determine what effect, if any, cortisone may have upon complement concentration in animal sera.

The Effect of Light on Carotenoid Synthesis in Corynebacterium 7E1C

The Effect of Light on Carotenoid Synthesis in Corynebacterium 7E1C

Date: May 1977
Creator: Endicott, George R.
Description: The effects of light, light "mimicking" chemicals, and protein synthesis inhibitors on the photo-induced carotenogenesis of Corynebacterium 7EIC were studied. Changes in the dosage of fluorescent light applied to dark grown cells showed a dose related carotenogenic response. Maintaining the same dosage but varying the wavelength of monochromatic light revealed that light with a wavelength of 280 to 450nm was responsible for photo-induction. It further showed a peak of photo-induction between the wavelengths of 370 and 430nm. The light "mimicking" chemicals antimycin A and p-Chloromercurybenzoate were shown to have no light "mimicking" effects. The transcriptional inhibitor of protein synthesis actinomycin D partially inhibited, and chloramphenicol a translational inhibitor, completely inhibited photo-induced carotenogenesis.

The Effect of Media Constituents on Growth and Pigment Production of Mycobacterium Phlei, Pseudomonas Fluorescens, Pseudomonas Aeruginosa, and Staphylococcus Citreus

The Effect of Media Constituents on Growth and Pigment Production of Mycobacterium Phlei, Pseudomonas Fluorescens, Pseudomonas Aeruginosa, and Staphylococcus Citreus

Date: 1947
Creator: Robbins, Finis E.
Description: Little is known concerning the production and significance of bacterial pigments. There is seemingly an open field for studying the effects produced by varying the nutritive content of culture media upon which organisms are grown. This has led to an especial interest in, and the purpose of this investigation.

The Effect of Medium Constituents upon Pigment Production by Four Species of Bacteria

Date: 1947
Creator: Goode, Jo Dunn
Description: This investigation had for its aim the determination of the effects of various materials, added to the basic culture medium, upon pigment production of the four chromogens Staphylococcus aureus, Sarcina lutea, Serratia marcescens, and Rhodococcus cinnabaris.

The Effect of Repeated Antigen Injections on the C' and C'4 Titers in Guinea Pig Serum

The Effect of Repeated Antigen Injections on the C' and C'4 Titers in Guinea Pig Serum

Date: June 1961
Creator: Teague, Perry Owen
Description: In this study the effects of repeated antigen injections on total complement (C') and C'4 of guinea pig serum were investigated to determine if constant antigenic stimulation would show changes in the C' and C'4 titers. Attempts were also made to correlate any changes with variations in antibody titers during the repeated antigen injections.
