The Effects Of Estradiol Benzoate On Protein Synthesis By The Isolated Perfused Snake Liver, William Ralph Boone
The Effects Of Estradiol Benzoate On Protein Synthesis By The Isolated Perfused Snake Liver, William Ralph Boone
Master's Theses
The effect s of estradios benzoate on protein synthesis by the isolated perfused liver of Natrix fasciata fasciata (Linnaeus, 1766), the southern banded water snake, were investigated. The incorporation of carbon-14 labeled leucine into plasma protein of the liver perfusate was used as an index of protein synthesis by the perfused liver.
Both control and experimental livers demonstrated incorporation of the labeled leucine into plasma protein. However, estrogen treated livers expressed significantly greater incorporation of the amino acid into plasma protein giving an almost linear response. Total plasma protein levels were also significantly higher in the perfusions involving estrogen treated …
Colonial Independence Of Feeding Among Zooids Of The Ectoproct Lophodella Carteri (Hyatt), Leonard M. Bahr
Colonial Independence Of Feeding Among Zooids Of The Ectoproct Lophodella Carteri (Hyatt), Leonard M. Bahr
Master's Theses
Possible interactions of feeding between zooids of colonies of the freshwater ectoproct Lophopodella carter! were investigated. Suspensions of Euglena gracilis at a concentration of 558x103 cells ml-1 were cleared by L. carter at a rate of 2.7 x 10-3 ml min-1 zooid-1 for15 minute periods. The rate of ingestion of E. gracilis by L. carter was independent of the size of colony and decreased exponentially with time, declining to about one third the original rate in 60 minutes.
Refractoriness Of Pet Mouse Integument To The Nerve Growth Factor, Walter Hollified Dorman
Refractoriness Of Pet Mouse Integument To The Nerve Growth Factor, Walter Hollified Dorman
Master's Theses
This paper deals with the refractoriness of PET mouse integument to the subcutaneous administration of nerve growth factor. Newborn mice were injected once daily with NGF through ten injections. Gross and histological examination showed that the skin of the experimental animals was completely unresponsive to this agent. No alterations in the hair growth cycle or pattern were observed.
