Abstract
Two children, ages 13 2/12 and 6 6/12 years, with osteogenesis imperfecta were treated with salmon calcitonin. During the course of therapy the older child developed calcitonin dose-related hypomagnesemia on two occasions. The younger child, coincident with otitis media and vomiting, developed hypomagnesemia, hypophosphatemia, hyponatremia, and hypokalemia. Since rib biopsies obtained before and after one year of treatment with salmon calcitonin failed to demonstrate any histologic changes, therapy was discontinued because of the induced metabolic consequences of calcitonin therapy.

Abstract
Pseudomonas putida strains with plasmids carrying pleiotropic alk mutations gave rise to alkane-positive "revertants," which differ from wild type. Some had restricted ability to utilize alkane and primary alcohol growth substrates, and others could grow on undecane and dodecanol, which are not utilized by alk+ strains. These revertants showed altered responses to normal inducers of alkA+, alkB+, and alkC+ activities. Some revertants were constitutive for these activities. Constitutive mutants could also be isolated directly from wild type, but they appeared spontaneously at a frequency of less than 2 X 10(-8). Regulatory mutations of all three types, pleiotropic negative, altered inducer specificity, and constitutive, were tightly linked in transduction crosses with a polar alkB mutation. These results demonstrate that the IncP-2 plasmid alk gene cluster constitutes a regulon. They also permit the identification of at least one cistron whose gene product participates in inducer recognition and suggest that the alkABC regulon is not under simple repressor control.

Abstract
The plasmid-determined inducible alkane hydroxylase of Pseudomonas putida resolved into particulate and soluble fractions. Spinach reductase and spinach ferredoxin could replace the soluble hydroxylase component. Two alkane hydroxylase mutants show in vitro complementation (S. Benson and J. Shapiro, J. Bacteriol., 123: 759-760, 1975): one, alk-7, lacks an active soluble component and the other, alk-181, lacks an active particulate component. Together with previous results on a particulate alcohol dehydrogenase enzyme (Benson and Shapiro, J. Bacteriol., 126: 794-798, 1976), these results allowed us to assay three plasmid-determined inducible activities: soluble alkane hydroxylase (alkA+), particulate alkane hydroxylase (alkB+), and particulate alcohol dehydrogenase (alkC+). Growth tests and in vitro complementation assays revealed three groups of plasmid mutations that block expression of alkane hydroxylase activity: alkA, which so far includes only the alk-7 mutation; alkB, which includes alk-181 and 11 other mutations; and a pleiotropic-negative class, which includes nine mutations that lead to loss of alkA+, alkB+, and alkC+ activities. Thus, the alk+ gene cluster found on IncP-2 plasmids contains at least four cistrons. We believe it is significant that two of these determined the presence of membrane proteins. The accompanying paper shows that these loci are part of a single regulon.

Abstract
The beta-lactamase gene from the RP1 plasmid transposes into at least two Pseudomonas putida degradative plasmids. Donor strains that carry RP1 (bla+ tet+ aphA+) and a degradative plasmid yield transconjugants that have only the bla+ marker of RP1. This occurs in up to 80% of all bla+ transconjugants. Segregation of the bla+ marker requires the presence of a degradative plasmid in the donor and is only observed in transconjugants that have received degradative markers. The bla+ tet aphA transconjugants show 100% linkage of bla+ to degradative markers in conjugation,transduction, and transformation crosses. A transduction cross of an (RP1), (SAL) donor shows that 8% of all SAL plasmids also carry the transposed bla+ marker. Tn401 is the name we assign to the bla+ transposon from RP1 observed in Pseudomonas. Its identity with the RP1 bla+ transposon observed in Escherichia coli is not known. In four cases, Tn401 has inserted into the camphor genes of the CAM-OCT plasmid.

Abstract
We have identified an alcohol dehydrogenase activity in Pseudomonas putida strains carrying the CAM-OCT degradative plasmid that were grown on octane. The activity is nicotinamide adenine dinucleotide independent, sediments at 48,000 x g, and shows 20-fold greater activity with octanol rather than butanol as substrate. The enzyme is inducible by unoxidized alkane and is present only in strains that have the OCT plasmid genes for alkane degradation with a wild-type alcO locus. No analogous chromosomal dehydrogenase could be detected. Wild-type and actanol-negative mutants (alcA-) without plasmids both contain a constitutive nicotinamide adenine dinucleotide-linked soluble alcohol dehydrogenase activity. This means that alcA- mutants are cryptic for octanol oxidation and suggests that the particulate plasmid-coded alcohol dehydrogenase activity is active on surface- or membrane-bound substrate.

Abstract
Five cases of the relatively uncommon intramammary lipoma and 4 cases of the rare adenolipoma were found in more than 5,000 patients who underwent mammography. The mammographic features of the intramammary and paramammary lipomata are given and the characteristic xeroradiographic appearance of adenolipomata is described. The 4 adenolipomata were only visualised by xeroradiography. The reason for these neoplasms being visible on xerograms and not on film mammograms is not clear, but we surmise that it is owing to the 'edge enhancement' phenomenon inherent in the xeroradiographic process. The question whether adenolipomata of the breast are true invasive tumours or mixed neoplasms is discussed.

Abstract
We have studied the appearance of whole-cell oxidizing activity for n-alkanes and their oxidation products in strains of Pseudomonas putida carrying the OCT plasmid. Our results indicate that the OCT plasmid codes for inducible alkane-hydroxylating and primary alcohol-dehydrogenating activities and that the chromosome codes for constitutive oxidizing activities for primary alcohols, aliphatic aldehydes, and fatty acids. Mutant isolation confirms the presence of an alcohol dehydrogenase locus on the OCT plasmid and indicated the presence of multiple alcohol and aldehyde dehydrogenase loci on the P. putida chromosome. Induction tests with various compounds indicate that inducer recognition has specificity for chain length and can be affected by the degree of oxidation of the carbon chain. Some inducers are neither growth nor respiration substrates. Growth tests with and without a gratuitous inducer indicate that undecane is not a growth substrate because it does not induce alkane hydroxylase activity. Using a growth test for determining induction of the plasmid alcohol dehydrogenase it is possible to show that heptane induces this activity in hydroxylase-negative mutants. This suggests that unoxidized alkane molecules are the physiological inducers of both plasmid activities.

Abstract
Pseudomonas putida PpG6 is able to utilize purified n-alkanes of six to ten carbon atoms for growth. It can also grow on the primary terminal oxidation products of these alkanes and on 1-dodecanol but not on the corresponding 2-ketones or 1,6-hexanediol, adipic acid, or pimelic acid. Revertible point mutants can be isolated which have simultaneously lost the ability to grow on all five n-alkane growth substrates but which can still grow on octanol or nonanol. An acetate-negative mutant defective in isocitrate lysase activity is unable to grow on even-numbered alkanes and fatty acids. Analysis of double mutants defective in acetate and propionate or in acetate and glutarate metabolism shows that alkane carbon is assimilated only via acetyl-coenzyme A and propionyl-coenzyme A. These results support the following conclusions: (i) The n-alkane growth specificity of P. putida PpG6 is due to the substrate specificity of whole-cell alkane hydroxylation; (ii) there is a single alkane hydroxylase enzyme complex; (iii) the physiological role of this complex is to initiate the monoterminal oxidation of alkane chains; and (iv) straight-chain fatty acids from butyric through nonanoic are degraded exclusively by beta-oxidation from the carboxyl end of the molecule.

Abstract
This study explored the relationship between sex-role development and response to taking medication by male and female psychiatric inpatients. The major hypotheses were that the more feminine an S's orientation the less resistance he would show to taking medication, the fewer adverse side effects he would report, and the fewer unusual body distortions he would acknowledge. All hypotheses were supported for women, and trends were noted for the second and third hypotheses for men. Differences between the men and women in length of hospitalization and drug treatment may account for the difference in results.
