Antibiotics And The Wasting Disease In Neonatally Thymectomized Rats, Douglas M. Grignon
Antibiotics And The Wasting Disease In Neonatally Thymectomized Rats, Douglas M. Grignon
Loma Linda University Electronic Theses, Dissertations & Projects
The administration of the antibiotic, Chloramphenicol, to pregnant rats just prior to, and for four days after delivery, diminishes the incidence of the so-called "Wasting Disease" in neonatally thymectomized rats.
A total of 50 rats were divided into the following groups:
- Thymectomy only---nonmedicated 17 rats
- Thymectomy only---medicated 12 rats
- Thymectomy-adrenalectomy---nonmedicated 5 rats
- Thymectomy-adrenalectomy---medicated 8 rats
- Controls---nonmedicated 4 rats
- Controls---medicated 4 rats
Chloramphenicol was administered in the drinking water to the mothers of groups 2, 4 and 6 for about 2 days prior to delivery and 4 days after. On the day of birth or within three days after birth, the …

An Analysis Of Orthodontic Treatment Results, William S. Asano
Loma Linda University Electronic Theses, Dissertations & Projects
A study of orthodontic treatment results was made on forty patients treated by the graduate students Loma Linda University. The purpose of the study was to determine the treatment changes in patients treated in the graduate clinic. The study was based on the findings of the cephalometric and full mouth radiographs. The distribution of the malocclusions were similar to those found in other studies. The group of forty patients was divided for paired comparisons of type of malocclusion, length of treatment, and extraction of teeth. Statistical correlations were computed on every change investigated in this study.

Mayo Dental Morphology, Val K. Artress
Loma Linda University Electronic Theses, Dissertations & Projects
The Mayo Indian of Sonora, Mexico, was selected for a study of dental morphology. The objectives of the investigation were to determine the extent to which the Mayo conformed to the four criteria of the Mongoloid dental master pattern, and to compare eight other specific tooth morphologic characteristics with like studies on Mongoloid and non-Mongoloid peoples. Plaster casts were made on a sample of forty-one Mayos.
The results of the study indicate that Mayos exhibit a 46 percent frequency of shovel-shape maxillary incisors, classifying "moderate shovel" and "shovel" together. The maxillary central-lateral width difference of 1.5 mm is small compared …
A Cephalometric Comparison Of The Chamula, Mayo And Navajo Indians, Norman C. Bunker
A Cephalometric Comparison Of The Chamula, Mayo And Navajo Indians, Norman C. Bunker
Loma Linda University Electronic Theses, Dissertations & Projects
Lateral head x-rays were obtained on selected samples of 24 Chamula, 29 Mayo and 39 Navajo Indians for cephalometric comparison.
Cephalometric evaluation was carried out by means of the Bjork analysis. Mean values for each of the Indian groups were determined and compared with each other and with the mean values of a group of Swedish conscripts studied by Bjork. The mean values were statistically analyzed and and subjected to the Student's "t" test to determine the significant levels of differences.
Results revealed that in comparing the three Indian groups significant differences do appear. They are few and general concordance …
