SEUCTED STUDIES ON THE ROLE OF BONE PHOSPHATASE IN CALClFICATION A s p a r t of the general study of the problem of calcification, special attention has been given the role of phosphatase which was first ascribed a major r o l e by Robison. A number of experiments have been performed with the aim of defining more precisely the specific part i n the calcification process played by phosphatase. Because the Robison theory of calcification is based on a nonexistent solubility product for the bone salt, this theory i s not tenable. . Robison's work, however, i s of lasting importance because he drew attention t o the possible part phosphatase may play i n calcification. The physiological role of phosphatase i n calcification seems t o be atleast twofold: of the bone matrix and (b) it protects the calcification process from (a) it may contribute i n some way t o the formation the inhibitory effect of ester phosphate. Attempts t o explain why ester phosphate exerts a beneficial effect on calcification have not been fruitful in giving a new theory of calci - f ication but considerable clarification of the problem has been achieved. It has been sham: respiration of ra chiti c cartilage. (a) That ester phosphate does not contribute t o the It i s not likely that phosphate esters maintain the calcifying mechanism by an effect on respiration. (b) That ester phosphate does not diffuse through a cellophane membrane at a faster rate than inorganic phosphate. ester phosphate and inorganic phosphate on calcification in vitro is probably not due t o differences in the rate of diffusion of the two The difference in the effects noted with ( c ) That phosphatase does not act as a transphosphorylase between

Reasons are given why this experiment mew approaches to this problem are under It has also been demonstrated that glycerophosphate i s hydrolyzed comparatively rapidly by phosphatase. that glycolytic inhibitors do not affect calcification --i n vitro when glycerophosphate is the source of phosphorus but are paterful inhibitors of calcification when biological esters are used. shown t h a t glycolyLic inhibitors are effective in inhibiting calcification because. of interference with cellular metabolism. a preformed surface, upon which mineral deposition takes place, deteriorates in the absence of cellular activity. Degeneration of the surface or template distorts the spatial arrangement of the phosphate groups there-. This inbibits the formation of the bone salt lattice. This sheds some light on the reason Further exploration has Tt is suggested that ...AT P is not beneficial t o calcification of ra chiti c cartilage from the rat i n v i t r o because (a) it is not attacked by the bone enzyme and only slightly by enzymes present i n the slice and (b) it forms only slightly dissociated complexes with calcium ion.

A STATISTICAL EVALUATION OF CERTAIN FACTORS Frank A . Smith and Rocco Della Rosa Factor idly designed experiments have been completed i n which the ’ influence of a number of factors involved i n the spontaneous plating of polonium from acid solutions were measured. From the results obtained, plating conditions were found such t h a t the standard deviation of a single determination is five per cent of the activity present. The experiments t o be described were undertaken i n order t o furnish a reliable estimate of the influence of a number of conditions operative i n the spontaneous plating of polonium from acid solutions. The first experiment was designed t o measure the effects on plating efficiency of temperature, time, volume of solution, stirring, acidity, and evaporation. Each of the six factors was tested a t two levels in a factorial - l y designed experiment. The quantity of polonium was kept constant and w a s equivalent t o 4000 counts per minute i n each smple. The factors and levels tested are listed in Table 1. A total of 32 platings were done. All foils were counted i n scintillation counters i n such a manner that the counting error did not exceed +- 2.5 per cent. The influence of each factor on plating efficiency was assessed by a statistical analysis of the counts obtained. he factorial experiments required were designed and analyzed by Drs. S. Lee Crump and A.M. Dutton of the Statistics Division. acknowledge our indebtedness for their assistance and cooperation. We are pleased t o

The data resulting indicated that the rate of stirring, and loss of volume by evaporation did not affect significantly the quantity of polonium plated on the foil. Efficiency of the plating process was improved a t the higher plating temperature, longer plating times, and i n the larger volume of plating solution. The efficiency also was somewhat greater i n the less acid solutions, though the improvement was quite s m a l l . It was concluded that the effects of time, temperature, initial volume, and evaporation need not be investigated further. solution, and of stirring appeared t o warrant further study. prove unnecessary, the design of the plating apparatus obviously would be The effects of lesser acidity of the plating

Accordingly, a second factorial experiment was prepared t o study further the effects of these factors. Three concentrations of acid were used, namely 0.1, 0.33 and 0.75N. Stirring was done a t as rapid arate as practicable, or eliminated entirely. The level of activity of polonium was 200 counts per minute. counts, and a third time at a level of 200,000 counts per minute. The experiment w a s repeated again, using 20,000 of 72 platings were made. ... The results obtained indicated again that somewhat better plating resulted at the lower normality of acid. Stirring of the solution definitely is required since in stirred solutior?s the quantity of polonium spontaneously plated waB approximately two times The improvement was slight, however. greater than was obtained i n unstirred samples. Using the IO5 observations made, the standard deviation was calculated t o be five per cent of the activity present for the range 200 - 200,000 counts per minute. The standard deviation vazied directly with the amount of A detailed report of these experiments, prepared i n collaboratlon with the Statistics Divlsion, will be issued later.

TaE EFFEET OF A S3FT DIET ON RADIATION ILLNESS IN THE DOG A Goft diet fed to dogs before and after an LD/50 exposure to x-ray was ineffective in reducing the degree or extent of gastro-intestinal hemorrhage. It has been suggested that a soft, low residue diet may alleviate the gastro-intestinal hemorrhage of acute radiation sickness. milk, non-nutritive cellulose fiber and Abbott's vitamin B elixir with crude liver was used. Ten dogs received this diet for one moth prior to rahiatiun asd awing the post-radiation period.

ON SENSITIZATION OF MICE To HISTAMINE William K. Cotton and Robert W. Miller From the results obtained, an exposure to x-irradiation resulting in a mortality of between an LD/lO-LD/l5 apparently does not,sensitize mice to histamine in dosage levels of either 50 mgm./kg. or 1000 mgm./kg. given between It has been sham by various workers that injections of sub-lethal doses of H. Pertussis vaccine into mice sensitizes these animals to relatively small amounts of histamine (1, 2, 3 ) . Kind (2) suggests that the vaccine injected may produce adrenal cortical damage and thus Interrupt the normal mechanism of response to stress. Parfentjev and Goodline (3) were able to demonstrate that 5 days after injection of H. Pertussis vaccine, 2 mg. of histamine diphosphate was as toxic to the sensitized mice as .5O mg. was to pormal animals. To date, the effects of ionizing irradiation upon the a d r e d cortex is Brayer, Ghsser and Duffy (4) have sham a temporary elevation in the excretion of adrenal. steroids following x-ray exposure in pigs. Little is known,harever, concerning the production of adrenal steroids following irradiation. Apparently, the adrenals are relatively radio-resistant. This experiment was devised to determine the effects of a plsximal T;D/O exposure of x-irradiation on the sensitization of mice to injections of

It would be expected that i-fl the deaths were due to sensitization to histamine, they would have o c c m e d vitbin 24-48hours after the administration of the histamine.

Abstract of Paper Presented at Chicago, Illinois April 6-io1 1953 There was little or no direct absoqtion of glucose-1-3hosphate from the intestine of the rat. However, the sugar phosphate and various other phoqhate compounds were rapidly hydrolyzed in intestinal loops. One of the products, orthophosphate, could be almost completely recovered i n the lumenal content 8 . The second product, glucose, was only partially recovered because of absorption of this substance from the intestinal lumen. The rate of hydrolysis of glucose-1-phosphate was about the same i n - all parts of the small intestine and also was the same i n excised loops as i n " i n vivo" loopse I n contrast the absorption of glucose was variable along the length of the intestine, and was markedly reduced in excised loops. When glucose-1-phosphate with P32 incorporated was hydrolyzed, there was no equilibration of labeled phosphate with the phosphate of the intestinal cells, indicating that the hydrolysis was _not taking place i n the interior of the c e l l s . Nor was any phosphatase secreted into the lumen under the conditions of these experiments. Therefore it i s concluded that the phosphatases concerned are bound on the surfaces of the intestinal cells.
