The case of acute arteria mesenterica superior syndrome--occurred in a boy aged 10, as rare complication of high voltage electro-trauma--is reported. The aetiology of the syndrome, as well as a possible new pathogenic factor are discussed. The clinical picture and the therapeutic principles are dealt with.
VA Subramanian and RL Berger. 1976. “Comparative evaluation of a new disposable rotating membrane oxygenator with bubble oxygenator.” Ann Thorac Surg, 21, 1, Pp. 48-54.Abstract
The comparative in vivo performance of adult-size bubble and rotating membrane oxygenators was evaluated during closed-chest cardiopulmonary bypass for six hours in two groups of dogs. The results show that the rotating membrane oxygenator is efficient in oxygen and carbon dioxide transfer with minimal trauma to blood, while platelet destruction and hemolysis were marked with the bubble oxygenator. Cerebral, cardiac, and respiratory complications were frequent with the bubble oxygenator and absent with the membrane oxygenator.
G Gardos and JO Cole. 1976. “Maintenance antipsychotic therapy: is the cure worse than the disease?” Am J Psychiatry, 133, 1, Pp. 32-6.Abstract
The serious long-term complications of maintenance antipsychotic therapy led the authors to undertake a critical review of outpatient withdrawal studies. Key findings included the following: 1) for a least 40% of outpatient schizophrenics, drugs seem to be essential for survival in the community; 2) the majority of patients who relapse after drug withdrawal recompensate fairly rapidly upon reinstitution of antipsychotic drug therapy; 3) placebo survivors seem to function as well as drug survivors--thus the benefit of maintenance drug therapy appears to be prevention of relapse; and 4) some cases of early relapse after drug withdrawal may be due to dyskinesia rather than psychotic decompensation. The authors urge clinicians to evaluate each patient on maintenance antipsychotic therapy in terms of feasibility of drug withdrawal and offer practical guidelines for withdrawal and subsequent management.
RC Prince and JM Olson. 1976. “Some thermodynamic and kinetic properties of the primary photochemical reactants in a complex from a green photosynthetic bacterium.” Biochim Biophys Acta, 423, 2, Pp. 357-62.Abstract
We have examined the bacteriochlorophyll reaction-center complex of Chlorobium limicola f. thiosulfatophilum, strain Tassajara. Our results indicate that the midpoint potential of the primary electron donor bacteriochlorophyll of the reaction center is +250 mV at pH 6.8, while that of cytochrome c-553 is +165 mV. There are two cytochrome c-553 hemes per reaction center, and the light-induced oxidation of each is biphasic (t1/2 of less than 5 mus and approximately 50 mus). We belive that this indicates a two state equilibrium with each cytochrome heme being either close to, or a little removed from, the reaction-center bacteriochlorophyll. We have also titrated the primary electron acceptor of the reaction center. Its equilibrium midpoint potential at pH 6.8 is below -450 mV. This is very much lower than the previous estimate for green bacteria, and also substantially lower than values obtained for purple bacteria. Such a low-potential primary acceptor would be thermodynamically capable of direct reduction of NAD+ via ferredoxin in a manner analagous to photosystem I in chloroplasts and blue-green algae.

The specificity of Ca++ for the interaction of beta adrenergic agonists with their receptors in rabbit right atrial muscle was evaluated. This was accomplished by substituting Ca++ by an equimolar concentration of Sr++. Dose-response curves which demonstrate the effect of norepinephrine and isoproterenol on the rate of electrical activity in the presence of Ca++ or Sr++ were made. In addition, the antagonistic action of propranolol (1 X 10(-7) M) in a Ca++-containing or Sr++-containing medium was determined. The results clearly demonstrate that Sr++ can effectively substitute for Ca++ in maintaining electrical and mechanical activity in cardiac muscle. Also, norepinephrine and isoproterenol can increase the rate of electrical activity in a Ca++ or Sr++-containing medium. This effect of these beta agonists is mediated through the beta-receptors since propranolol effectively blocked their action. It appears that Ca++ per se is not required for beta agonist or antagonist-receptor interaction in cardiac muscle. The results are discussed in relation to the dependency on extracellular Ca++ for beta agonists to cause a change in the rate of electrical activity after receptor occupancy.

(--)-alpha-Bisabolol has a primary antipeptic action depending on dosage, which is not caused by an alteration of the pH-value. The proteolytic activity of pepsin is reduced by 50 percent through addition of bisabolol in the ratio of 1/0.5. The antipeptic action of bisabolol only occurs in case of direct contact. In case of a previous contact with the substrate, the inhibiting effect is lost.
JC Jaton, H Huser, Y Blatt, and I Pecht. 1975. “Circular dichroism and fluorescence studies of homogeneous antibodies to type III pneumococcal polysaccharide.” Biochemistry, 14, 24, Pp. 5308-11.Abstract
The near-ultraviolet circular dichroism (CD) of three homogeneous anti-type III pneumococcal antibodies in the absence and the presence of the specific hexasaccharide ligand was studied. In addition recombinations and hybridizations of H and L chains derived from two of these antibodies were carried out and the CD spectra of bound and free reconstituted IgG molecules were measured. The results indicate that the CD spectra of the native antibodies in the 260-310-nm range are very similar in shape and sign and exhibit a positive band at 285 nm. The homologous reconstituted antibody molecules exhibited CD spectra very similar in shape and sign to those of the native antibody molecules although recombinant molecules are no longer stabilized by interchain disulfide bonds. Upon addition of the hexasaccharide ligand, a significant decrease in amplitude of the CD spectra (18-21%) occurred in all three native antibodies and their Fab fragments as well as in the homologous recombinant molecules. No CD spectral changes could be detected upon interaction of the hapten ligand with the heterologous recombinants. All homogeneous antibodies studied exhibited fluorescence quenching upon oligosaccharide binding and a blue shift of the emission maximum. This property allowed the determination of the binding constant of one selected antibody to be made. Taken together, CD and fluorescence spectroscopic data suggest that oligosaccharide ligands induced detectable conformational changes in the Fab fragment of the antibody.

The diagnostic specificity of a new method to detect obstructive jaundice by determination of lipoprotein X (LP-X) was tested in 144 patients with different kinds of hepatic diseases and compared with the usual chemical "obstructive jaundice specific" tests, such as bilirubin, SGOT, SGPT, alkaline phosphatase, LAP and gamma-GT. The LP-X test was performed by using all-in test kit LP-X Rapidophor" low-voltage electrophoresis of Immuno AG/Wien. The results were correlated with the histological classification of the liver biopsy specimen. In 82% of the histologically verified cases of obstructive jaundice the result of the LP-X test was positive, whilst in 98.5% of the histologically negative cases the result of the LP-X test was negative. Hence, this LP-X method proved superior to chemical methods in providing a clear-cut positive or negative answer to the presence of cholestasis. Furthermore, the LP-X test was suitable for long-term follow-up investigation of patients with obstructive jaundice.
