Abstract
This research tested the proposition that closed-minded persons will restrict sensory input and interpersonal relationships. 303 high and low scorers on dogmatism, self-attitude, and self-reliance scales were compared for food-avoidance and reference-other relationships. While there was no significant difference in number of foods tasted and rejected, the closed-minded had tried significantly fewer foods. There was no difference in number of reference others but the closed-minded felt significantly greater constraint regarding the perceived importance of, control of, and accountability to their reference others. The theoretical consistency of these findings is discussed.

Abstract
Attempts to produce anti-D in rhesus-negative men using reconstituted frozen rhesus-positive cells were unsuccessful. The use of cells coated with IgM anti-D for immunisation stimulates anti-D production, and a comparison between two groups, one having cells coated with IgM anti-D, and the other having identical cells without coating suggests that there is an enhancement of the immune response when IgM-coated cells are used.

Abstract
Bovine skim milk galactosyltransferase (EC 2.4.1.22) retained its catalytic activity after partial enzymatic removal of sialic acid and galactose. Desialylated and degalactosylated galactosyltransferase was a galactosyl acceptor in the galactosyltransferase reaction. [14C]Galactose from UDP-[14C]galactose was incorporated into the carbohydrate-depleted galactosyltransferase by native galactosyltransferase. The results suggest that galactosyltransferase participates in the biosynthesis of its glycopeptides of the sialic acid-galactose-N-acetylglucosamine type.

Maintenance of the functional state of isolated rat liver by hypothermic perfusion with an erythrocyte-free medium. Transplantation 1977; 23:136-41.

Abstract
Isolated rat liver was studied before, during, and after hypothermic perfusion at 5 C for 24, 48, or 72 hr with an acellular perfusate consisting of 7% bovine serum albumin in Kreb-Ringer buffer containing glucose, penicillin, and streptomycin. Bile production ceased at 5 C but resumed when the temperature was raised to 35 C. The rate of flow and the total amount produced was unaffected by 24 hr of hypothermia but decreased when the cooling period was extended to 48 and 72 hr. The data of other workers was used to show a correlation between bile flow and oxygen consumption by the liver. Cooling also caused the release of potassium into the perfusate but it was quickly reaccumulated after rewarming; however, the extent and rate of reaccumulation decreased as the cooling period increased, as did the ability of the livers to retain the ion. Urea synthesis did not cease after cooling and after rewarming, the rate of synthesis increased as the period of hypothermia was lengthened. The maximum concentration of urea in the perfusate was found when rewarmed livers had produced 200 mumol of urea but at this point, control livers had produced 280 mumol. The concentration of glucose in the perfusate of livers maintained at 35 C showed peaks at 2 and 9 to 10 hr after the start of perfusion. After cooling for 24 hr these peaks arose at 2 and 7 hr after rewarming, but with 48 hr of hypothermia, these peaks were higher and appeared at 2 and 4 hr. When the cooling period was extended to 72 hr, only a single peak was seen 2 hr after rewarming. These results suggest that rat liver can be cooled to 5 C for 24 hr with little effect on its functional characteristics but a marked decline becomes apparent when the cooling period is extended beyond 24 hr. None of the livers studied was transplanted after perfusion and it remains to be seen how the functional tests conducted in vitro correlate with the ability of the livers to support life.

Abstract
Populations of symbiotic Rhizobium meliloti extracted from alfalfa nodules were shown by flow microfluorometry to contain a significant number of bacteroids with higher nucleic acid content than the free-living rhizobia. Bacteroids with lower nucleic acid content than the free-living bacteria were not detected in significant quantities in these populations. These results indicate that the incapability of bacteroids to reestablish growth in nutrient media may not be caused by a decrease in nucleic acid content of the symbiotic rhizobia.

Abstract
A technique is presented that enables the particle-size analysis of quasicircular particles to be made. A coherent optical system is used to generate the diffraction pattern of the particle population to be analyzed, and a digital computer is used to process the information in the pattern. A similar technique has been used earlier, with success, to count circular particles of varying diameters. A scene containing three classes of particles is analyzed, and results are furnished.

Abstract
In combined pancreatoduodenal trauma, the surgeon usually chooses a diverting or resectional procedure at substantial risk. Simple closure of the duodenum and transposition of the common duct was accomplished at early operation in an 18-year-old boy who had almost complete transection of the duodenum with avulsion of the ampulia of Vater from blunt abdominal trauma. Transgastrojejunostomy and use of Chaffin tubes were discontinued prior to discharge from the hospital three weeks later. The postoperative course was complicated only by a brief pancreatitis. The excellent result persists more than two years later. In similar anatomic situations, consideration might be given to this operative approach.

Abstract
The toxicity of several cryoprotective agents was tested at room temperature (23 C) against Tetrahymena pyriformis strain S (Phenoset A) at different stages of growth cycle. Polyvinylpyrrolidone (PVP-40) at 10 per cent (v/v) concentration was without effect at any stage in the growth cycle, while 1.2 M glycerol immobilized the cells which were disrupted very shortly afterwards. The toxicity of 0.25 M glucose was largely independent of the position of the cells in the growth cycle, but the toxicity of 0.25 M sucrose and 1.4 M dimethylsulfoxide (DMSO) was most marked in late log- and stATIONARY-PHASE CELLS. After log-phase cells had been equilibrated with 1.4 M DMSO for 1 hr, the number of cells surviving cooling at defined rates from 0.45 to 12 C/min decreased as the final temperature decreased from -30 to -60 C. A temperature of -53 C was found to be the optimum from which cells cooled at a given rate could be cooled rapidly to -196 C. Nevertheless, when cells were cooled at defined rates to -35, -45, or -53 C and then rapidly to -196 c the optimum rate of cooling to these temperatures was found to be 1 C/min. The optimum rate of cooling to -60 C prior to plunging into liquid nitrogen was found to be 2.7 C/min.

Abstract
An extension of a new technique that enables parallel, simultaneous processing of remotely obtained images is presented. The technique holds out promise for automatic on-board classification of data. The central feature involves the generation of binary masks, directly from the image, based on object reflectance data, that groups objects into equivalence classes. These masks, called equivalence class masks, can be used in various logical combinations to isolate classes of objects with a priori known reflectance or radiance signatures. Experimental verification of the technique is furnished for simple scenes. A computational scheme, based on a sequence of integrated irradiance measurements on the image, that enables the identification of objects within an equivalence class is suggested.
