Radioprotection Of Oral Cavity Structures By S-2-(3-Aminopropylamino) Ethyl Phosphorothioate (Wr-2721), Ronald King
Radioprotection Of Oral Cavity Structures By S-2-(3-Aminopropylamino) Ethyl Phosphorothioate (Wr-2721), Ronald King
Masters Theses & Specialist Projects
Studies reporting a high concentration of WR-2721 in mouse salivary glands led to our studies of possible radioprotection of these glands by this drug from ionizing radiation. Oral effects of radiation in the presence of WR-2721 were studied in mice and dogs. Histological evaluation of mouse salivary glands irradiated with 1000 rads of 60Co showed essentially no difference between control and experimental animals. Almost full regeneration of the serous salivary components occurred by 6 months in both groups and neither group had changes in the mucous glands. The use of higher doses of radiation in the mouse was prevented …
Population Dynamics And Tackle Catch Susceptibility Of The Smallmouth Buffalo, Ictiobus Bubalus (Rafinesque), In Rough River Lake, Kentucky, Alan Waite
Masters Theses & Specialist Projects
The population of the smallmouth buffalo, Ictiobus bubalus (Rafinesque), was studied in Rough River Lake, Kentucky, from July, 1974, through June, 1975. A total of 758 individuals were collected with 587 being marked and returned.
From calculations made using poison population sample data, population size was estimated to be between 150,00 to 225,000 adult fish or 29 to 44 fish per acre. Scales were studied to determine age and through back calculation, the total length of each fish at the time of each annulus formation determined. Ten year ciasses were observed with the majority of the fish in age groups …
