Regeneration of the gastrocnemius muscle in 25 white rats was reinvestigated using reimplantation of minced muscle fragments in order to compare the fiber profiles of the regenerate and normal contralateral gastrocnemius. Fiber profiles were prepared from both the regenerate and the normal muscle 45 days postoperatively using myosin ATPase histochemistry.Counts made of type 1, 2A, 2B, and 2C fibers showed a significant (P<(0.05) change in the profile of the regenerated muscle compared to the contralateral muscle.The results indicated that although there was a change in the fiber profile at 45 days, the regenerated muscle appeared to follow a path of developmental recapitulation. Changes in the fiber appeared to be related to reinnervation of the regenerate.Ball State UniversityMuncie, IN 47306

This project was undertaken to develop an effective community wide educational program designed to reduce the incidence of tap water burns in children. A random phone survey was conducted to determine the level of awareness of the problem. Various educational methods were employed over a five-month period. A follow-up random phone survey was done to assess the level of effectiveness of the methods employed.Ball State UniversityMuncie, IN 47306

Benzylpenicillin, a-aminobenzylpenicillin, phenoxymethylpenicillin, and 2,6-dimethoxy-phenylpenicillin were incubated with whole human blood. Migration patterns into human erythrocytes were compared spectrophotometrically.A possible inhibition effect by chloroquine on benzyl-[14C]-penicillin in red blood cells was studied via a Beckman LS-100C Liquid Scintillation Counter.An intraerythrocytic protein, carbonic anhydrase, was investigated as being responsible for the hydrolysis of benzylpenicillin. Three carbonic anhydrases (a, b, and c) were quantitatively measured via a Beckman IR 4250 Spectrophotometer for their effect upon the a-lactam ring of benzylpenicillin.Ball State UniversityMuncie, IN 47306

The Hayes Arboretum Solar Greenhouse located in Richmond, Indiana, at 39° 50' N latitude, 84° 50' W longitude has been operational since December 1, 1976. Temperatures inside the 1000 square foot greenhouse were maintained at 55°F. minimum, 85°F. maximum. Data on gas usage was collected over a 24 month period (December 1, 1976 - November 30, 1978). Temperature data was collected during months when auxiliary heat was necessary to supplement the greenhouse.The solar greenhouse was designed by the author to test the feasibility of solar energy in Indiana. Solar energy provided 27% of heating needs during the two year period. A total of 77% of the energy needed to run a convencial design features."Fuel" (natural gas + collector pump electricity) costs were 11.8 ¢ /sq. ft./year for the solar greenhouse compared to 51 ¢ /sq. ft./year for conventional greenhouses during the same period.Ball State UniversityMuncie, IN 47306

Previous investigations have utilized extremes of diet and exercise during the week prior to a performance to raise muscle glycogen levels to 220 mmoles/kg wet tissue. This investigation was designed to determine if muscle glycogen levels can be supercompensated utilizing a combination of a depletion-taper sequence and diets of 15% carbohydrate (CHO, LC), 50% CHO (M), and 70% CHO (HC) in 3,000 kcal. Each depletion-taper sequence was conducted on a treadmill at 73% V02max and consisted of runs of 90, 40, 40, 20, 20 minutes and a day of rest on the six days prior to a 13 mile performance run. Trial C consisted of 3 days LC and 3 days HC; Trial B, consisted of 3 days M and 3 days HC; and Trial C, 6 days M. Muscle biopsies were obtained from the gastrocnemius prior to loading (day 4) and before and after the performance run. Trials A, B and C elevated muscle glycogen to 207, 203 and 160 mmoles/ kg wet tissue, respectively. Trials A and B resulted in significantly more glycogen utilization (105 and 107 mmoles/kg wet tissue, respectively) than did Trial C (65 mmoles/kg wet tissue). The times during the performance runs were not significantly different between the Trials. It is concluded that: 1. muscle glycogen levels can be supercompensated to levels comparable to previous investigations by employing a depletion-tapering sequence and less severe alteration in diet prior to competition; 2. carbohydrate loading is not necessary for trained runners preparing for a race of 13 miles.Supported by the National Dairy Council and the Ball State University Graduate Student Research Fund, 1980.Ball State UniversityMuncie, IN 47306

This work was a kinetic study of the Diels-Alder reaction of isoprene with variously substituted benzalmalononitriles. Application of the Hammett equation, a linear free energy relationship, to the kinetic rate data yielded a value of 1.31 for rho. This was interpreted as meaning the transition state for this Diels-Alder reaction was probably of the concerted type, although the nonconcerted polar transition state could not be eliminated in one case by the data of this study.Ball State UniversityMuncie, IN 47306

This thesis supported the hypothesis that preoperative verbalization enhances the birth experience in primary emergency cesarean delivered women. A T-test was utilized to compare the two groups' responses on each item of a 29 point questionnaire. The questionnaire measured perception of birth in 28 participants who verbalized their feelings preoperatively and 22 participants who did not verbalize preoperatively. The total mean score for all 29 items indicated a favorable perception for the former group. In addition, six specific items were significantly favorable for the group who verbalized. The T-test revealed questionnaire items of significance in the following subgroups: age, duration and intensity of labor, and parity.Ball State UniversityMuncie, IN 47306
