Comparison Of Root Surfaces In Endodontic Lesions, Periodontic Lesions And Normal Human Teeth, Robert W. Hanson
Comparison Of Root Surfaces In Endodontic Lesions, Periodontic Lesions And Normal Human Teeth, Robert W. Hanson
Loma Linda University Electronic Theses, Dissertations & Projects
The healing potential of an endodontic lesion is usually greater than a periodontic lesion (Simon et al. 1972; Hiatt 1977). Periodontal regeneration places particular emphasis on the soft tissue-tooth interface (Stahl 1977). This interface was examined in fifteen extracted human teeth.
The teeth were divided into three groups: (1) periapical lesions, (2) periodontal lesions, and (3) healthy periodontal tissue. Criteria were established for each group. Freshly extracted human teeth meeting the criteria were fixed in gluteraldehyde or paraformaldehyde. The teeth were then selected for surface observation or cracked for cross sectional examination. The teeth were post fixed, dehydrated, and coated …
Effects Of Trypanosoma Musculi Kendall, 1906 Immune Serum On The Reproduction Of Trichinella Spiralis (Owen, 1835) Railliet, 1896 In Mice, Samuel L. Chafin

The possible effects of ablastin, a reproduction-inhibiting antibody which is produced during the infection of the blood parasite, Trypanosoma musculi in the mouse, were investigated by fractionating the parasite into a supernatant fraction (designated as Group A test mice) and a pellet fraction (Group B test mice). These groups A and B mice were injected with the respective fractions, plus Freund’s Complete Adjuvant (FCA). Control mice were injected with FCA only. Sera from these three groups of mice were removed after the Group A and Group B mice were shown to be negative to T. musculi challenge, and Group A …
Effect Of Time And Diet On The Immune Status Of Mice Challenged With Herpes-Transformed Cells, Daila S. Gridley
Effect Of Time And Diet On The Immune Status Of Mice Challenged With Herpes-Transformed Cells, Daila S. Gridley
Loma Linda University Electronic Theses, Dissertations & Projects
Human Herpes simplex virus type 2 (HSV 2)-transformed Balb/c mouse cells (H238 cells) are malignant in Balb/c mice. The immune stratus of mice bearing H238 cell-induced tumors was studied and changes in immune response with time and with altered diet of the mice were measured.
In the experiments dealing with the status of immunity with time after tumor cell injection, mice were fed Purina Laboratory Chow (P.L.C.), injected with H238 cells, and sacrificed three to eight weeks post-injection. In the diet experiments, groups of mice were fed either P.L.C. or one of six equicaloric diets, consisting of low or high …
