Abstract
Malignant fibrous histiocytoma occurs most commonly in the extremities and trunk, but rarely in visceral organs. This report documents a case of malignant fibrous histiocytoma arising in the terminal ileum. Following surgical resection, there is no evidence of recurrence or metastasis in this patient after one-year follow-up studies.

Abstract
The inactivation kinetics of bacteriophage f2 were studied by using ozone under controlled laboratory conditions. The phage were rapidly inactivated during the first 5 s of the reaction by 5 and 7 logs at ozone concentrations of 0.09 and 0.8 mg/liter, respectively. During the next 10 min, the phage were further inactivated at a slower rate in both treatments. The [
3
H]uridine-labeled f2 phage and its ribonucleic acid (RNA) were examined to elucidate the mechanism of ozone inactivation, utilizing adsorption to host bacteria, sucrose density gradient analysis, and electron microscopy. The specific adsorption of the phage was reduced by ozonation in the same pattern as plaque-forming unit reduction. RNA was released from the phage particles during ozonation, although it had reduced infectivity for spheroplasts. Electron microscopic examination showed that the phage coat was broken by ozonation into many protein subunit pieces and that the specific adsorption of the phage to host pili was inversely related to the extent of phage breakage. The RNA enclosed in the phage coat was inactivated less by ozonation than were whole phage, but inactivated more than naked RNA. These findings suggest that ozone breaks the protein capsid into subunits, liberating RNA and disrupting adsorption to the host pili, and that the RNA may be secondarily sheared by a reduction with and/or without the coat protein molecules, which have been modified by ozonation.

Abstract
A case of Henoch-Schönlein purpura (HSP) with renal lesions is presented. The clinical, laboratory, and morphologic findings revealed features commonly described in HSP. A renal biopsy revealed diffuse, generalized, proliferative glomerulonephritis. The unusual findings in this case were numerous electron-dense subepithelial deposits ("humps") and a few small intramembranous deposits in the glomerular capillaries without deposits in the mesangium, mimicking those of acute poststreptococcal glomerulonephritis. The electron-dense deposits were well correlated with deposits of IgG, IgA, C3, C4, C1q, and fibrin-fibrinogen demonstrated by immunofluorescent microscopy.

Abstract
The molar absorbance of cyanmethemoglobin at 540 nm was measured in 35 species of mammals, birds, and reptiles. Values obtained were compared with those measured on human cyanmethemoglobin by the same procedure. There was no significant difference (P greater than or equal to 0.1) between the human and animal blood values observed in 29 samples. In six cases (4 mammals, 1 reptile, and 1 bird), the significant difference (P greater than or equal to 0.05) did not exceed 5% of the human value. The practice of applying the accepted absorbance of 1.10 x 10(4) M-1 cm-1 per mole of iron in human cyanmethemeglobin for the analysis of animal blood will not cause more than 5% uncertainty. Such results are satisfactory for use in clinical veterinary medicine except for those research projects concerned with animal hemoglobin function and structure.

Abstract
The ability of Eikenella corrodens to cause endocarditis in catheterized rabbits was studied. E. corrodens 1073, the serum-resistant strain used in the study, was isolated from a human periodontitis lesion. Thirty-four rabbits, surgically catheterized across the aortic valve and injected intravenously 24 to 48 h later with 10(7) to 10(9) log-phase organisms, were studied. Only three rabbits developed positive blood cultures and only two rabbits died before the time of sacrifice at 14 days after infection. Autopsies showed that all rabbits developed aortic vegetations, 52% of which were culture positive for E. corrodens. The organisms were recovered from aortic vegetations in a mean concentration of 10(5.3) colony-forming units/g of tissue and from liver or kidney in 28% of the animals in concentrations from 10(2) to 10(4) colony-forming units/g. Indirect immunofluorescent staining of vegetations, with the use of specific rat antiserum to E. corrodens 1073 and fluorescein isothiocyanate-labeled goat antirat serum, revealed colonies of E. corrodens in culture-negative vegetations as well as in those which were culture positive. The results showed that E. corrodens was an effective pathogen in the rabbit model of endocarditis, in which the disease was infrequently bacteremic and rarely fatal.

Abstract
Mycoplasma pneumoniae sprain CL-8 was studied by using various surfaces for adherence and growth. Cells grown on Epon 812, Formvar, carbon, and glass were of similar morphology. Thin Epon pieces were good material for culturing the organisms and examining thin-sectioned microcolonies by transmission electron microscopy.

Abstract
The dissolution of a solid immersed in a solvent was considered as a consecutive process, consisting of a primary surface interaction leading to the production of a new surface at the solid-liquid interface, solvation of the solid at the interface, and transfer of the solvated solid into the bulk of the solution. The energy changes involved in each step were studied for the dissolution of m-tolylacetamide in hexane and heptane. An energy diagram was constructed according to the proposed dissolution mechanism. The heats of dissolution determined from the energy diagram agreed well with those obtained experimentally.

Abstract
A mathematical analysis of solute flow in a descending column following dissolution is presented. The acceleration of a solute particle from zero velocity, when it is in the solid phase, to its final equilibrium descending velocity was analyzed. The maximum velocity for N-(3-methylphenyl) acetamide developed essentially at the solid-liquid interface, contradicting the postulate of a microsize diffusional layer. The possibility of a diffusional layer existing for solids of lower solubility than N-(3-methylphenyl)acetamide is discussed.

Abstract
SUMMARY
The concentrations of luteinizing hormone (LH), progesterone, testosterone, androstenedione, oestrone and oestradiol in mixed umbilical cord blood taken from foetal calves during months 3 to 9 of gestation have been measured by radioimmunoassay. The levels of progesterone were low (compared with those in maternal plasma) and constant during pregnancy. There were large variations in the concentrations of androstenedione, oestrone, oestradiol and LH, with lower values found during months 7 to 8 of gestation. Significant differences (P < 0·05–< 0·001) in hormone levels between male and female foetuses were found for testosterone, LH, and the oestrogens during months 3 to 7, 3 and 4, and 7 and 8, respectively. No significant differences (P > 0·05) between sexes were found at any time between the concentrations of progesterone and androstenedione.
