The Effects Of Prolonged Ultraviolet Irradiation On The Pigment System Of Pet/Wmr Mouse Epidermis, Penny Suzanne Nair

Master's Theses

Repeated exposure to ultraviolet radiation brings about an increase in the DOPA-positive melanocyte population of the human. However, there is an age-dependent decline in the melanocyte population regardless of UV irradiation. In the rhesus monkey, a drop in the DOPA-positive epidermal melanocyte population has been observed after prolonged UV irradiation. The population of DOPApositive epidermal melanocytes in PET/Wmr mice reaches a peak during the first post-natal week after which the number of cells declines, fading almost completely within 3 weeks. Their occurrence in adult mice is rare. With UV irradiation (300 nm) the melanocyte population of newborn and adult PET …

The Effect Of Photoperiod On The Regressive Phase Of The Ovarian Cycle Of The Lizard, Anolis Carolinensis., John Dickens Pinch

Master's Theses

The effects of constant photoperiod (14 hours of light) and decreasing photoperiod (13-8 hours of light) on the regressive phase of the ovarian cycle of the lizard Anolis carolinensis were investigated. Changes in body, liver, ovary and oviduct weights were measured and microscopic examinations of several ovarian parameters were made. In both light regimens body and liver weights decreased over the first four weeks of the experiment but both increased at the sixth week. In addition, ovary weight was highly variable but exhibited a decreasing trend and oviduct weight decreased. There were decreases in the number of previtellogonic follicles and …

Seasonal Nearshore Distributions Of Fishes In A Piedmont Section Of The James River, Virginia, Eugene George Maurakis

Master's Theses

The seasonal nearshore distributions of 17 species of fishes were determined in natural and artificially heated areas in a 9.6 km stretch of the Piedmont section of the James River, Virginia from July, 1973 to June, 1974. Analyses of the seasonal distributions were based on abundance and percent frequency of occurrence data. The maximum abundance and percent occurrence of ten of the 17 species of fishes in natural temperature areas occurred in early autumn. Deviations from this pattern included Notropis analostanus, equally abundant throughout the year, and Lepisosteus osseus, Notropis amoenus, Notropis ardens, Notropis rubellus, Catostomus commersoni and Lepomis macrochirus, …

The Modification By Temperature Of The Effects Of Mammalian Follicle Stimulating Hormone And 17b-Estradiol On The Process Of Vitellogenesis In The Lizard, Anolis Carolinensis, Susan Howard Early

Master's Theses

The effects of porcine follicle stimulating hormone, 17B-estradiol, and a combination of the two on the process of vitellogenesis were studied in Anolis carolinensis maintained at 15C with no light for one week, and then at 15C or 32C with 14 hours of light for two additional weeks.

At both temperatures, the control animals subjected to 14 hours of light possessed greater numbers of previtel­logenic follicles and lower liver weights than the control animals sacrificed after one week in the dark. Animals maintained at the higher temperature and given different hormonal treatments showed significant increases in ovary and oviduct weights, …

The Relationship Between Gill Na+ + K+ -Activated Adenosine Triphosphatase Activity And Sodium Regulation In Acclimation Of The Blue Crab, John Lewis Harris

Master's Theses

Evidence from this study suggests that Na++K+-activated ATPase is involved in the ionic regulation of sodium in the hemo-lymph of the blue crab in low salinity environments. The time course of changes in gill Na++K+-ATPase specific activity follow- ing transfer of crabs from JO o/oo to 5 o/oo salinity indicates that a major increase in activity occurred within 2.5-3.0 hr. Apparently, a 8.8-11.1% decrease in hemolymph sodium ion concen-tration to about J55-J60 meq/1 in approximately 2-J hr was sufficient to activate the ATPase cation transport system in the gills of Callinectes sapidus. Following enzymatic activation, hemolymph sodium concentration gradually approached …

The Role Of An Eyestalk Extract In The Regulation Of The Blood Sodium And Calcium Concentrations Of The Blue Crab Callinectes Sapidus, Gregory Martin Ivy

Master's Theses

The effect of bilateral eyestalk ligation or ablation on the blood Na+ and ca++ concentrations of the euryhaline blue crab, Callinectes sapidus, was measured in 10 o/oo and 5 o/oo sea water. The ablations caused a significant decrease in the blood Na+ and ca++ over a 24 hour period. The serum Na+ level increased significantly 6 hours following injections of an eyestalk extract whereas the blood total ca++ level did not change significantly. Eyestalk ligation, however, did not cause significant blood Na+ and ca++ changes. The blood Na+ level of intact crabs increased significantly in acclimating to colder water when …

Populations Of Lepomis Auritus (Redbreast Sunfish) In A Thermally Influenced Section Of The James River, Virginia, John Rawls Saecker

Master's Theses

From October 1971 - September 1973, electrofishing was used to collect 1004 specimens of Lepomis auritus (year classes 0 - V) from a thermally influenced section of the James River near Blemo Bluff, Virginia. Collections of fish from the natural and heated water temperature habitats were analyzed as to year classes, season, length and sex.

The Effects Of Topical Nitrogen Mustard On The Pigment System In Pet/Wmr Mouse Epidermis, Ronald Lee Salisbury

Master's Theses

Miniature melanocytes have been observed scattered among the typical melanocytes in the skin of the PET/Wmr mouse strain, They are weakly DOPA reactive and their cell bodies and nuclei are one quarter the size of those in typical melanocytes, Both populations reach a peak during the first postnatal week and then gradually disappear within the following three weeks. The miniatures appear very early and are among the last cells to disappear. During the first postnatal week, their population remains relatively constant against a radically changing population of typical melanocytes. That they may represent a stage in the development of typical …

Melanin In The Longnose Gar, Lepisosteus Osseus, George William Minson

Master's Theses

Examination was made of the melanophores of three Lepisosteus osseus (longnose gar), one dark, one intermediate, and one normal in pigmentation. Melanophore counts were made per mm² from anterior, mid, and posterior areas of both the dorsal and ventral surfaces of each of the three fish. The data were tested with a four-factor analysis of variance. By microscopic examination the melanophores were classified as to branching in the sample areas. Neither number of melanophores nor degree of branching explained divergence in pigmentation. However, divergence was attributed to the melanosome color and concentration in the melanophores.

Effects Of The Toxins Of The Ectoproct, Lophopodella Carteri, On Oxygen Consumption In Gill Tissues Of The Bluegill, Lepomis Macrochirus, Barbara Harper Green

Master's Theses

Large and small bluegill, Lepomis macrochirus, were exposed to homogena tes of Lophopodella carteri, an ectoproct that contains substances toxic to some gilled vertebrates. Oxygen consumption tests on the excised gill tissues of the bluegill indicated that the ectoproct toxins caused a lowering of oxygen consumption of the gill tissues. Oxygen consumption of the gill tissues of the smaller fish was reduced to a greater extent than that of larger fish. An inverse relationship was found be tween the temperature of the medium and the period of time for death to occur. It is proposed that the toxins cause physiological …
