Blood samples from 160 native dogs in 3 northwestern counties of Ohio were examined for Dirofilaria immitis microfilariae during 1976; 6 samples (3.75%) were positive. A comparison was made with data collected in 1971 from the same counties and dogs in the same infection risk stratum. The level of prevalence of D. immitis has remained stable from 1971 (3.04%) through 1976 (3.75%) in these northwestern Ohio counties. Dipetalonema reconditum was not diagnosed in the present study, although a 3.8% prevalence was recorded in 1971.

The low molecular weight amino acids, N-a-benzyloxycarbonyl-L-lysine and L-lysine, and the amino sugar derivative, N-acetyl-D-glucosamine, were examined for effects on the immune response of mice to sheep erythrocytes. Treatment dosages of 1000, 100, 50 and 10 mg/kg of the test compounds did not alter the body weight, organ weight or peripheral leucocyte count of test mice. Mice given N-a-benzyloxycarbonyl- L-lysine demonstrated significant increases or decreases in the splenic plaqueforming cell response to sheep erythrocytes depending on the treatment regimen employed. Animals given N-acetyl-D-glucosamine showed an increase in the splenic plaque forming cell response while those receiving L-lysine had no detectable alteration.
When analyzing data which deals with repeated testing, one may find that extreme scores are regressing away from the mean, contrary to what one would expect based on the regression effect. This paper discusses the regression effect and presents the argument that when these contrary results occur, they are indicative of the violation of the underlying assumption of rectilinearity. One should be required to look for non-linear relationships when interpreting such data. In addition, three methods for determining whether or not non-linear relationships exist in data are suggested and briefly discussed.
Serological evidence was obtained that demonstrated previous infection with Pasteurella tularensis in 2 of 9 sheep raised in Monroe County, MI. Although no ectoparasites were found on the sheep in April and May when the testing was done, it was assumed that they were infected by ticks. Titers for Brucella were much less than those for P. tularensis and were not considered meaningful. Eight New Zealand white rabbits from nearby Risingsun, OH were serologically negative for tularemia and brucellosis. These animals had been confined in a commercial rabbitry and were free of ectoparasites. One of 8 dogs from Fulton County, OH, had a positive titer for P. tularensis, but not Brucella. No ectoparasites were observed on the dogs, but they had been recently dipped. The possibility that man as well as other animals might become infected with Pasteurella tularensis in the Toledo, OH area exists.

Candida albicans is found to occur in the oral cavity of individuals, whether or not they have oral disease. In our survey, 79 subjects were grouped according to oral rinse colony counts and clinical examinations as being noncarriers of C. albicans, non-diseased carriers of C. albicans, or diseased carriers of C. albicans. Answers to a number of questions on medical history, dietary practices and oral hygiene were recorded. Data obtained were tested by the Chi Square test, and 2 categories showed significant differences between noncarriers of C. albicans, non-diseased carriers of C albicans, and diseased carriers of C. albicans. More individuals in the noncarrier and diseased carrier groups were regular alcoholic beverage drinkers; and more individuals in the non-diseased carrier of C. albicans and diseased carrier of C. albicans groups were hormone users.

Data on nutritive quality of vegetation for stripmined lands were obtained in 1972-73 from 2 Ohio counties, one having generally acidic spoil banks and the other having calcareous spoils. Proximate analysis of water, ash, crude protein, ether extract, cell-wall constituents, and nitrogen-free extract revealed few significant differences between plants growing on stripped and undisturbed (control) plots. Plants also were analyzed for 6 essential elements by emission spectrography. Levels of potassium were significantly higher in plants from control plots. Calcium levels were higher in plants from alkaline spoils, and manganese levels were higher in plants from acidic mined plots. Manganese levels exceeded 600 ppm in some plant samples from acidic spoil banks. Even when plants from stripped plots contained significantly less of a given element, levels were generally not low enough to indicate nutrient deficiency.
Immediately after the War for Independence, Americans began to move westward in earnest. There were numerous factors pulling migrants westward, among them the fertile land which had a particular appeal for farmers. Ohio felt the impact first; settlement of Wisconsin was delayed until opening of the lead mines during the later Indian wars. Settlers in the Northwest Territory revealed a penchant for the exploitation of the territory's resources and the creation of educational institutions. Excellence of the soil led to significant agricultural expansion and, later, to growth of an innovative food industry. Mineral resources stimulated the growth of a metals industry and an energy industry based first on coal, then on petroleum. The extensive forests in the northern part of the territory supplied a forest products industry. Pioneer developments took place without benefit of science but after 1850 science took on increasing significance as the colleges and universities prepared individuals for a role in the innovative growth of agriculture, industry, and medicine. A critical question revolves around the disproportionate regional excellence in science (chemistry in particular) shown by universities and colleges of the region.
