Twenty-two cows with right-sided displacement of the abomasum were treated with hyoscine-n-butyl bromide and dipyrone (Buscopan compositum; Boehringer Ingelheim). Within 24 hours 11 had recovered completely, three had improved, six had shown no improvement and two had been slaughtered. Within 48 hours 17 of the cows had recovered completely and five had been slaughtered.

Four out of more than 8,200 Staphylococcus aureus strains isolated in Japan between 1961 and 1980 were constitutively resistant to a variety of macrolide antibiotics except tylosin and rokitamycin, but susceptible to lincosamide and streptogramin type B antibiotics (PM). The data obtained by agarose gel electrophoresis, CsCl-ethidium bromide density gradient analysis, diagnosis with ATP-dependent deoxyribonuclease, and a test transducing into a rec- mutant with phage 80L2 propagated on PM-resistant S. aureus all suggested that the determinant for the PM-resistance is located in chromosome.

The enamel organ of growing rat incisors was perfusion-fixed with a mixture of formaldehyde and glutaraldehyde and processed for ultracytochemical demonstration of ouabain-resistant, K+-stimulated p-nitrophenylphosphatase representing the second dephosphorylative step of H-K-ATPase by use of the one-step lead method. Throughout the stages of amelogenesis, the enzymatic activity was found in the plasma membranes, mitochondrial membranes, and lysosomal structures of the cells of stratum intermedium, papillary layer, and ameloblast layer. Gap junctions and desmosomes between these cells were, however, free of reaction product or showed slight precipitates of reaction. The stellate reticulum and the outer enamel epithelium at the stage of enamel secretion were usually negative for reaction. Although secretory, transition, and ruffle-ended maturation ameloblasts showed enzymatic activity at their basolateral cell surfaces, their distal cell surfaces facing the enamel were always free of reaction product. On the other hand, the smooth-ended maturation ameloblasts seldom showed a positive reaction, except in lysosomes and along their basal cell surfaces. An energy-dispersive X-ray microanalysis of reaction products of H-K-ATPase in unosmicated tissue sections demonstrated that they were composed of lead and phosphorus, which had been released during the dephosphorylation of substrate. In cytochemical controls, the enzymatic activity was completely dependent on substrate and potassium ion, resistant to ouabain and levamisole, and inhibited by nolinium bromide, a specific inhibitor of H-K-ATPase. In addition, inorganic trimetaphosphatase as enzymatic marker of lysosome was localized in dark and pale lysosomes, phagosomes, multivesicular bodies, and ferritin-containing vesicles of the ameloblasts and the cells of stratum intermedium and papillary layer. These membrane-bound structures were also positive for H-K-ATPase reaction. These results suggest that: 1) H-K-ATPase functions to maintain an acidic internal pH of lysosomes in the enamel organ cells; and 2) H-K-ATPase localization in the plasma membranes of enamel organ cells is concerned with efflux of protons derived from cytoplasmic water.

Vibrio cholerae biotype el tor strain BM2508, resistant to trimethoprim, 0/129, streptomycin and spectinomycin was isolated from the faeces of a child with severe diarrhoea. Resistance to trimethoprim and 0/129 was due to a dihydrofolate reductase type I and resistance to streptomycin-spectinomycin to a 3'',9-aminoglycoside-aminocyclitol adenylyltransferase. The resistance genes were not transferable to Escherichia coli and, as inferred from ultracentrifugation in cesium chloride-ethidium bromide and agarose gel electrophoresis of crude bacterial lysates, were located on the chromosome. The resistance genes were transposed to multiple sites of plasmids belonging to incompatibility groups 6-C and P, introduced in BM2508 and were subsequently transferred to E. coli (rec-), Salmonella typhimurium, V. cholerae and V. parahaemolyticus strains where they re-transposed into the chromosome. Analysis of plasmid DNA from the transconjugants by agarose gel electrophoresis following digestion with HindIII and by Southern hybridization using a ColEl::Tn7 probe indicated the presence of a 14-kilobase transposon, Tn1527, closely related to Tn7. The emergence of Tn1527 in V. cholerae may lead to prophylactic and therapeutic failures due to trimethoprim resistance and to bacterial misidentification because of cross resistance to 0/129.

The effects of ethidium bromide (EB) on rat adrenocortical cells were investigated by biochemical and stereological methods. It was found that a treatment with ip. injections of 10 microgram/gm of EB every 12 hours induced a persistent inhibition of the incorporation of 3H-thymidine and 3H-uridine into the mitochondrial fraction, but not into the nuclear fraction. Chronic treatment with this dose of EB provoked in zona fasciculata cells of rats treated with maintenance doses of ACTH a noticeable decrease in the volume of the mitochondrial compartment (due to the decrease both in the number per cell and in the average volume of the organelles) and in the surface area of the mitochondrial cristae. These findings lend support to the hypothesis that the mechanism underlying the ACTH-induced maintenance of the growth of adrenocortical mitochondria involves mitochondrial DNA reduplication and transcription.

Incubation of skin in 2 N sodium bromide allows separation of dermal and epidermal layers leaving an intact basal lamina covering the dermal portion. Examination of the surface of the dermis by SEM shows cells migrating through the basal lamina. By scanning and transmission electron microscopy, these cells have the characteristics of lymphocytes. The migrating lymphocytes produce a sequence of basal lamina deformations including dome formation, effacement of corrugations, and central fenestrations with hole formation allowing lymphocyte passage. Following passage there is reestablishment of a relatively smooth basal lamina in the crater base, effacement of the crater rim, and finally reformation of basal lamina corrugations. This deformability of the basal lamina supports the hypothesis that basal lamina is thixotropic. This study is the first demonstration in three dimensions of lymphocyte traffic across the basal lamina, an important component of skin-associated lymphoid tissue (SALT).

Eighteen Belgian white and blue double-muscled calves suffering from the acute respiratory distress syndrome were studied. Fifteen of the calves inhaled ipratropium bromide (0.6 mg) four times a day for three to four days whereas the other three control calves inhaled sterile 0.9 per cent saline. All the animals were injected with ceftiofur sodium (1 mg/kg/day) for five days, the first injection being given one hour after the first inhalation of ipratropium bromide or saline. Arterial oxygen tension, alveolar arterial oxygen difference, carbon dioxide tension and arterial pH, respiratory and heart rates, oscillatory resistance and phase angle, measured by the mono-frequency forced oscillation technique, were recorded both before and one hour and 168 hours after the first inhalation. The measurement of oscillatory resistance and phase angle made it possible to resolve the impedance of the respiratory system into its real and imaginary components. The oscillatory compliance (Cosc) was determined from the imaginary component (Im). By one hour after the first inhalation of ipratropium bromide the oscillatory resistance was already significantly reduced and Im and Cosc had significantly increased, but the other parameters showed no significant improvement. However, between one hour and 168 hours after the first inhalation all the parameters reached physiological values. The control calves did not show any change. It was concluded that the pulmonary dysfunction associated with the acute respiratory distress syndrome in these calves was at least partly due to a severe bronchoconstriction.(ABSTRACT TRUNCATED AT 250 WORDS)

Staphylococcus aureus TPR-27, a clinically isolated strain, showed constitutive resistance to some macrolide antibiotics (erythromycin, oleandomycin, spiramycin, and josamycin), but susceptibility to the other macrolide (tylosin, rokitamycin, and mycinamicin), lincosamide, and streptogramin type B antibiotics (PM-resistance). The PM-resistant strain TPR-27 has carried for visible plasmids. Attempts to eliminate the resistant determinant in terms of ethidium bromide (about 3 micrograms/ml) did not succeed, and every trial to transduce the PM-resistant determinant into rec- mutant ISP105 using phage 80L2 propagated on strain TPR-27 also failed at the frequency of less than 1.1 x 10(-10) transductants per plaque-forming unit. These results suggest that the PM-resistance determinant is localized in chromosomal DNA.

Two aerosolised bronchodilators, one sympathomimetic and one parasympatholytic, were tested either alone or in combination for their ability to improve the pulmonary function of double-muscled calves suffering from acute respiratory distress syndrome. In control animals treated with 0.9 per cent saline the parameters of pulmonary function and signs of clinical distress did not change significantly within the hour following the first treatment. Among the other animals, both at one hour and seven days after the first treatment, the most clinical improvement was observed in the animals treated with both bronchodilators and the least in the animals treated with clenbuterol hydrochloride. One hour after the first treatment the respiratory system compliance of the animals treated with ipratropium bromide and the arterial oxygen tension of the animals treated with both bronchodilators were significantly enhanced. After seven days the resistive parameters, the rectal temperature and the respiratory rate were also significantly improved in the animals treated with ipratropium bromide or both bronchodilators whereas only the respiratory rate and rectal temperature were significantly reduced in the animals treated with clenbuterol hydrochloride.

Previous studies of colonic epithelial cell kinetics in mice and rats revealed a pattern similar to small intestine, where basally located stem cells proliferate, differentiating as they migrate towards the surface epithelium. Vacuolated and goblet cells are assumed to co-migrate at the same rate. The present study indicates that rabbit distal colon has more complicated epithelial cell kinetics. The zone of proliferation was detected immunohistochemically using proliferating cell nuclear antigen (PCNA) and confirmed with the use of colchicine to arrest dividing cells in metaphase. Migrating cells were tracked from the zero-hour position (PCNA labeling, mitosis) to positions 24, 48, 72 hrs by monitoring cell migration with the thymidine analog 5-Bromo-2-Deoxyuridine (BrdU). PCNA revealed a major proliferative zone in the upper third of the crypt column and the presence of mitotic figures after colchicine corroborated these results. Differentiated vacuolated cell proliferation was detected at three crypt sites: base, middle, and top of the crypt, while columnar cells arose from a population of dividing cells at the top of the crypt. Turnover of columnar and vacuolated cells occurred within 72 hrs. Goblet cells exhibited maximal proliferation at the crypt base and migrated at a much slower rate than the other cell types. In rabbit distal colon, populations of proliferating cells exist at multiple levels of the crypt column. Vacuolated and goblet cells differ in their labeling indices and migration rates, suggesting that the two cell types arise and migrate independently.
