Vitamin B-6 status was examined in a group of 46 elderly subjects who were selected from nursing home residents, hospital patients, and free living individuals in Denton County. Subjects were limited to men and women over 60 years of age. Erythrocyte aspartate aminotransferase stimulation with pyridoxal phosphate (in-vitro) was studied as the biochemical criterion of vitamin B-6 status. The pyridoxine status of these 46 subjects (the reference group) was measured in order to be able to identify people with a relatively poor B-6 status. A sub-group of the reference group was composed of 4 subjects who took B-6 supplements (supplemented group). There was no significant difference (0.05 level) in the basal activity, stimulated activity, percentage stimulation, or body weight, after treatment with 10 mg pyridoxine hydrochloride for 4 weeks, even though all 4 subjects had an improved B-6 status (based on percentage stimulation) after taking the supplement. The data indicated that of the 4 subjects tested, 2 showed a large change in the basal activity, stimulated activity, and percentage stimulation. The lack of significant difference (0.05 level) was probably due to a small sample size. One subject reported an increased appetite and body weight after treatment with pyridoxine.

An environmental evaluation concerning land designated for park and recreation development was conducted in Flower Mound, Texas. Results were compared with the findings of a public opinion survey of the citizenry of Flower Mound. The first section is an introduction to land use and recreation planning. Section two presents a review of pertinent literature concerning environmental evaluation and recreation and recreation planning. Third is a brief description of Flower Mound, Texas, and existing park properties. The fourth section discusses both the environmental evaluation and the survey research techniques employed. Results of the environmental evaluation are examined in section five. The public opinion survey results are discussed in the sixth section. Flower Mound is fortunate to have a number of sites suitable for recreational development. If recreational development is to be successful and satisfactory to the users, decisions will need to be made in an organized fashion. Park and recreation planning should be incorporated within a general land use planning framework.

Dominant genera of bacteria were isolated from three river waters during anthracene and pentachlorophenol biotransformation studies. The genera Pseudomonas, Acinetobacter, Micrococcus, Chromobacterium, Alcaligenes, Azomonos, Bacillus, and Flavobacterium were capable of biotransforming one or both of these compounds. These isolates were subjected to further biotransformation tests, including river water and a basal salt medium with and without additional glucose. The results of these experiments were evaluated statistically. It was concluded that only a limited number of the bacteria identified were able to transform these chemicals in river water. The addition of glucose to the growth medium significantly affected the biotransformation of these chemicals. It was also determined that the size of the initial bacterial population is not a factor in determining whether biotransformation of anthracene or pentachlorophenol can occur.

Wretlind, Heden, and Wadstrom found ammonium sulfate to be inhibitory for the formation of extracellular protease in Aeromonas hydrophila grown in Brain Heart Infusion medium. They demonstrated by manipulating the iron and zinc content within their medium that it is possible to differentially affect the accumulation of hemolysin and protease by A. hydrophila grown in batch culture. Further manipulation of the composition of this medium was done in the present study to determine the effect of other components on the production of protease. The purpose of this study was to determine the factors affecting the level of A. hydrophila protease produced in a chemically defined medium.

This study compared the sexual knowledge and sexual attitudes of college students. Utilizing the Sex Knowledge Inventory - Form Y and the Valois Sexual Attitudes Questionnaire, data was gathered from 203 students. Analysis of the data concluded no significant differences between the sexual knowledge of or the sexual attitudes of male and female subjects. A significant difference, at .01, was found between the attitudes of subjects scoring either low or high in sexual knowledge. Individuals with lower knowledge expressed less accepting sexual attitudes, while those with higher knowledge expressed more accepting sexual attitudes. Lastly, the correlation of sexual knowledge with attitude indicated a positive association to exist between high sexual knowledge and various' sexual topics.

This study was designed to determine whether black journalists who work at black newspapers in Texas felt the Civil Rights movement had affected their industry. Although black newspapers lost an exclusive market for talent that now must be shared with majority-owned newspapers, this report concludes that the operation of black newspapers virtually was unaffected by the Civil Rights movement. It is recommended that this research serve as a starting point for a continuing examination of black newspapers. It would be particularly beneficial if more information could be gathered from people who have worked at now-defunct black newspapers.

The problem undertaken in this study was an attempt to discover the image Texas Baptists have of their eight colleges and universities, and to recommend steps to ensure a positive image. The two methods used to determine the image was a questionnaire distributed through a weekly newsmagazine, the Baptist Standard, and telephone interviews. From the study it was concluded that Texas Baptists have a positive image of their eight colleges and universities and rely on the Baptist Standard for their information. The major strength of the eight colleges and universities is the spiritual emphasis, and the major weakness is the high cost of attending a private college or university.
