The Effect Of Self-Help Support Groups On Self Esteem And Blood Glucose In Young Insulin-Dependent Diabetics, Linda L. Woertz Aug 1982

The Effect Of Self-Help Support Groups On Self Esteem And Blood Glucose In Young Insulin-Dependent Diabetics, Linda L. Woertz

Loma Linda University Electronic Theses, Dissertations & Projects

Successful adaptation to diabetes is probably a function of many factors: the stress involved, the rewards, the motivation of the individual, and the self concept. The more optimal the self concept the more optimal the behavior may be. By helping the patient shape a positive self concept, a base can be built for blood glucose control (Bruhn, 1977, pp. 93-97). One method of improving self concept or self esteem may be through the development of self-help support groups for diabetics.

The purpose of this study was to evaluate the effect of self-help support group intervention on the levels of self …

Strange Males Block Pregnancy In Lactating Pine Voles, Microtus Pinetorum, And Reduce Survival And Growth Of Nursing Young, Margaret H. Schadler Mar 1982

Strange Males Block Pregnancy In Lactating Pine Voles, Microtus Pinetorum, And Reduce Survival And Growth Of Nursing Young, Margaret H. Schadler

Eastern Pine and Meadow Vole Symposia

Strange (unfamiliar) males affect survival of progeny of reproductive female rodents in a variety of ways. In mice, strange males block pregnancy before implantation of embryos (Bruce, 1959) but only in females that are not lactating (Bruce and Parkes, 1961). In voles these males can block pregnancy both before and after implantation (Stehn and Richmond, 1975; Marks and Schadler, 1979; Schadler, 1981). Strange males have also been shown to kill nursing pups in lemmings (Mallory and Brooks, 1978) and mice (Labov, 1980 and vom Saal and Howard, 1982).

The present study in pine voles (Microtus pinetorum) examines the …

Organometallation of the unsubstituted dihydroisoquinoline provides the 1-substituted tetrahydroisoquinoline. The 1-benzyl-, 1-n-butyl-, 1-ethyl-, 1-methyl-, and 1-phenyl-1,2,J,4-tetrahydroisoquinolines were prepared. The use of Grignard and …


Algal Dynamics In A Cypress Stand In The Seasonally Flooded Great Dismal Swamp, Joseph A. Atchue Iii Oct 1981

Algal Dynamics In A Cypress Stand In The Seasonally Flooded Great Dismal Swamp, Joseph A. Atchue Iii

Biological Sciences Theses & Dissertations

The dynamics of epiphytic algae and phytoplankton were studied at a cypress stand in the Great Dismal Swamp, Virginia. Mean epiphytic algal biomass was 19.9 g m-2 and mean planktonic biomass was 3.4 g m-2.Nutrient concentrations in the epiphytic algae and the litter were determined. The algae had mean concentrations of 1.67% and 0.18%. They were found to immobilize as much as 0.5 g N m-2 and 0.06 g P m-2. This suggests that the algae are important as nutrient conservers. The phytoplankton were composed primarily of Bacillariophyceae. They exhibited a more or less …

Protective Effects Of Certain Lythraceae Alkaloids And Homologs In Croton Oil- And Carrageenan-Induced Inflammation, John Alan Byrne Jan 1981

Protective Effects Of Certain Lythraceae Alkaloids And Homologs In Croton Oil- And Carrageenan-Induced Inflammation, John Alan Byrne

University of the Pacific Theses and Dissertations

Cryogenine's immunosuppressive activity was first evaluated by Kosersky, et al. (21) who, impressed by the drug's ability to inhibit both the irritant- and immune- mediated phases of adjuvant-induced polyarthritis (11), quantitatively confirmed this activity and clearly differentiated the action of cryogenine from that displayed by 6-mercaptopurine. A definitive study by Watson and Malone (22) confirmed cryogenine's lack of immunosuppressive capacity at effective anti-inflammatory dose levels.

The molecular complexity of the lythraceae alkaloids suggests that several active centers may account for their unique pharmacological profile. To assess these potentially active sites, two standard models of acute inflammation were selected for use …

The Coronary Distribution Zone : Mathematical Modelling Of The Left Ventricular Epicardial Surface For Area Calculation, Three-Dimensional Rotaton And Display, S. Matts E. Sjölander

Loma Linda University Electronic Theses, Dissertations & Projects

A computer model of the left ventricular (LV) epicardial surface was developed from Jang’s truncated ellipsoidal model, which has a minor to major axis ratio of 6:10. The model was applied in calculating the area of a segment of the myocardium, jeopardized by an impending occlusion of its associated artery. The endangered segment of the LV muscle was also visualized in different projections by rotations in three space and graphical displays simulating the three dimensions.

The area formula for the surface of the ideal model , a truncated prolate spheroid, was derived and used in producing maps for manual calculations …

The Effect Of Natural Measures To Aid In Sleep As Compared With The Use Of Flurazepam 30 Milligrams As Seen In The Hospitalized Male Patient, Myra Ladd Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

Sleep is necessary for physical and psychological restoration of the body. Studies indicate that tissue repair is augmented during sleep, showing that rates of protein synthesis and of mitotic division are higher at times of rest and sleep. Studies evaluating sleep-deprived subjects reveal that after loss of normal sleep, some types of memory and learning processes are impaired. These subjects generally become anxious and irritable, especially after loss of dreaming sleep.

Sleeping medications have been implicated by observers and researchers to be a cause of altered sleep patterns. These medications not only disrupt normal sleep cycles, but their continued use …

A Comparative Study On The Frequency Of Respiratory, Gastrointestinal, And Allergic Disorders Between Bottle-Fed And Breast-Fed Infants From Birth To Twelve Weeks Of Age, Sylvia C. Souza

Loma Linda University Electronic Theses, Dissertations & Projects

Questions concerning the advantages of breast-feeding have been debated since the introduction of commercially-prepared formula about 50 years ago. Some recognized benefits of breast milk include less respiratory as well as other Infections, less allergy in infancy and later life, and a lower morbidity rate in less-developed countries. From 1955 to 1971 in the United States there was a decline in the incidence of breast feeding related to several factors which included the introduction of formula, mothers returning to the work force, and strict maternity units' rules and routines. Since 1971 to the present there has been a resurgence in …
