Isorhythmic atrioventricular dissociation during enflurane anesthesia.

Isorhythmic atrioventricular dissociation occurs in a substantial number of patients undergoing enflurane anesthesia. It causes a decrease in the systemic blood pressure that may be detrimental especially in patients with poor cardiac reserve. The most satisfactory method treating this arrhythmia is to discontinue enflurane and substitute another anesthetic agent.

Transformation of calcium fluoride for caries prevention.

Oral application of fluoride for caries prevention may tend to form calcium fluoride (CaF 2) instead of the desired fluorapatite. In view of this, the transformability of CaF2 to fluorapatite has been studied. This investigation shows that CaF2 can be converted to fluorapatite in phosphate solutions ar various temperatures ranging between 25 and 75 degrees C in the pH range of 6.5 to 8.5. In the initial stage, phosphate ions, believed to be HPO4= adsorb on the particle surface. A dissolution/precipitation mechanism is proposed for the growth of fluorapatite.

Sporadic bovine leukosis: a description of eight calves received at Animal Diseases Research Institute from 1974-1980.

Eight calves with sporadic bovine leukosis are described. The common features were generalized lymphadenopathy, visceral involvement and raised total leukocyte and lymphocyte counts. Agar gel immunodiffusion tests for bovine leukemia virus antibodies were negative in eight animals and in all animals from three herds of origin. Lymphocytic nuclear pockets were found in the tissues of one calf but attempts to isolate bovine leukemia virus from two animals were unsuccessful.

A simple, rapid syncytial-inhibition test for antibodies to bovine leukemia virus.

Cocultivation of equal numbers of cells from a fetal lamb kidney line infected with bovine leukemia virus and African green monkey (Vero) cells results in the rapid production of syncytia. The effect was blocked or inhibited by serum containing antibodies to bovine leukemia virus. A serological test based on syncytial inhibition was compared to the agar gel immunodiffusion test and the modified direct complement fixation test for the detection of bovine leukemia virus antibodies in sera from leukosis-free cattle, cases of adult enzootic bovine lymphosarcoma and cattle from herds in contact with enzootic lymphosarcoma. The results showed the syncytial inhibition test to react positively with sera from all cases of adult enzootic lymphosarcoma, but to be much less sensitive than the other tests in detecting bovine leukemia virus antibodies in sera of exposed animals.
