Abstract
To assess the effect of thickening of feedings on gastroesophageal reflux and gastric emptying, 20 infants were examined with technetium scintigraphy and detailed behavioral observation after each of a pair of feedings, one with radiolabeled infant formula alone and the other with radiolabeled formula thickened with dry rice cereal. The thickened and unthickened meals were followed by similar amounts of scintigraphically demonstrated gastroesophageal reflux. However, the number of episodes of emesis (1.2 +/- 0.7 vs 3.9 +/- 0.9 per 90 minutes postprandial), the percent of gastric emptying at 30 minutes (17.8% +/- 2.7% vs 22.4% +/- 2.4%), the time spent crying (11.7 +/- 3.1 minutes vs 17.6 +/- 3.8 minutes per 90 minutes), and the total time spent awake (45.2 +/- 5.9 minutes vs 53.1 +/- 4.9 minutes per 90 minutes) were significantly less after the thickened feedings. Because thickening of infant feedings increases the caloric density, decreases emesis, decreases crying time, and increases sleep time in the postprandial period, it is likely to be beneficial in the treatment of infants with gastroesophageal reflux associated with failure to thrive.

Abstract
The title phosphines, Ph2P(CH2).PPh2 (n = 2-5), react with lithium in tetrahydrofuran to give the corresponding 1, n-dilithio-1, n-di(phenylphosphines) directly with little or no intermediacy of the 1-lithio- 1-phenyl- n- diphenylphosphinoalkanes which can, however, be obtained by arylation of the diphosphides. Methylenebisdiphenylphosphine and 1,4-diphenyl-1,4-diphosphinane undergo exclusive phosphorus-alkyl carbon cleavage. The chemistry and 31P n.m.r. spectroscopy of the diphosphides are described and the mechanism of the cleavage reaction is discussed. Some cleavage reactions in liquid ammonia are described.

Abstract
An activity has been purified 350-fold from extracts of mouse plasmacytoma cells that forms 5-hydroxymethyluracil (alpha-hydroxythymine) and apyrimidinic sites with phage SPO1 DNA, which contains this base in place of thymine. This DNA glycosylase presumably functions to eliminate hydroxymethyluracil, a major thymine-derived DNA lesion produced by ionizing radiation and oxidative damage. The enzyme has no cofactor requirement and is active in EDTA. Neither intermediate formation nor hydrolysis of hydroxymethyl-deoxyuridine or hydroxymethyldeoxyuridine monophosphate was detected. The enzyme does not cleave apyrimidinic sites in DNA. It does release uracil from the uracil-containing DNA of phage PBS2, but this activity is less than 2% of the predominant uracil DNA glycosylase activity of the cell, which is separated by phosphocellulose chromatography. The major uracil DNA glycosylase does not release hydroxymethyluracil from SPO1 DNA. The hydroxymethyluracil glycosylase is also separated upon phosphocelluose chromatography from a thymine glycol DNA glycosylase activity that is accompanied by an apyrimidinic endonuclease activity.

Abstract
We compared auranofin (AF) in a single blind multi-centre study with gold sodium thiomalate and D-penicillamine in the treatment of rheumatoid arthritis. Adult patients with disease duration 6-60 months without previous treatment with gold salts with persistent active disease, were included. Thirty-nine patients, 13 in each treatment group, have so far been entered. Cumulative toxicity data and some results of efficacy assessments in those completing 9 months of treatment are presented. AF is very well tolerated, judgment concerning efficacy must await the end of the trial.

Abstract
The sublingual absorption rates, the sustained effects, te biologic activity, and the metabolism of micronized 17beta-estradiol (E2) were measured in 10 postmenopausal women. E2 (0.5 mg) was administered in a single sublingual dose to five of the patients. An alternate-day schedule with the same dosage was used for the other five patients. In the single-dose study, a twenty-six fold increase in serum E2 and a ninefold increase in serum estrone (E1) concentrations were observed 1 hour after the sublingual deposition of E2 (0.5 mg). Serum concentrations of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) were significantly decreased within 6 hours. The rise in E2 was early and peaked in the first 2 hours. The rise in E1 was slower and progressive, reaching its maximum thirteenfold increase at 4 hours, and remained two and one half times the baseline of 29 pg/ml at 24 hours, whereas E2 returned to the baseline level of 24 pg/ml. When micronized E2 was given in a dosage of 0.5 mg sublingually every other night, increased circulating levels of estrogens continued to be elevated at a minimum two and one-half fold baseline level for the week of study.

Abstract
Recently, there has been increased interest in the influence of maternal prenatal nutrition on the course and outcome of pregnancy. Evidence has accumulated that a woman's weight before pregnancy and the weight gained during pregnancy directly affect infant birth weight, incidence of neonatal mortality, and growth and development of the infant during the first year of life. Although recent recommendations for weight gain in pregnancy have been liberalized, a survey of 195 pregnant women who had prenatal visits in both clinic and private offices showed deficiencies in their understanding of the subject. Some 37 percent of women believed they should gain 20 pounds (9 kg) or less during pregnancy. Eight percent admitted to dieting before at least one antenatal visit and 54 percent thought their doctor would not be concerned about too little weight gained during pregnancy. This suggests that many women and some doctors are still ignorant of current concepts of proper nutrition during pregnancy. Apparently, increased lay and professional educational efforts are needed.

Abstract
The Survey Psychiatric Assessment Schedule (SPAS) was used in a survey of elderly people living at home and in institutions to examine its reliability in determining mental state. A psychiatrist assessed the same subjects using the Geriatric Mental State Schedule (GMSS) and classified psychiatric disorder into three broad groups: organic disorders, schizophrenia and paranoid disorders, and affective disorders and psychoneuroses. The agreement between the psychiatrist's classification of mental state and the classification derived from SPAS was found to be satisfactory for organic disorders and less satisfactory for functional disorders. The limitations of this method of identifying psychiatric illness are examined.

Abstract
A total of 125 patients with rheumatoid arthritis were investigated about their drug therapy before referral to a specialist centre. Most referrals were from general practitioners. Only 47 of the patients had received salicylates as the first drug and 18 had never had them at all. Soluble aspirin was the preparation of salicylates most frequently prescribed (for 63 patients). Only 60 patients had been given an adequate dose and only 62 an adequate course of treatment with salicylates. In 28 patients salicylates had been stopped on account of side effects. About one-third of the patients had been prescribed oral corticosteroids.The referral letters were poor in giving details of past and present drug therapy, and there were serious omissions in reporting of previous side effects.Seventy-five general practitioners were asked to rate several currently marketed antirheumatic drugs in terms of effectiveness. Though prednisolone 15 mg daily ranked higher than aspirin 4 g daily the difference was not significant. The study shows the inadequacies of drug prescribing for rheumatoid arthritis in the Glasgow area.

Abstract
Sixty-nine 24-hour electrocardiographic monitoring sessions were conducted in 54 ambulatory subjects. Thirty-one had coronary heart disease (CHD); 11 had miscellaneous heart ailments; and 12 were free of any heart disease. Monitoring was accomplished with a miniaturized cassette recorder and ventricular premature beats (VPBs) were analyzed as to incidence and grade. The occurrence of VPBs during sleep hours was compared to the awake state.
In 22 patients, the incidence of VPBs was reduced by at least 50% during sleep. An additional 13 patients showed a reduction of 25 to 50%. If patients free of ectopic activity during 24-hour monitoring sessions are excluded from analysis, then in 35 of 45 patients, or in 78%, sleep was associated with a lowered occurrence of ventricular extrasystoles. During sleep the VPB grade was likewise lowered. Thus the mean grade for 45 patients changed from 2.75 while awake to 1.78 while asleep. It is of interest that in a number of these patients, trials of various antiarrhythmic drugs were less effective than sleep in reducing the incidence and grade of VPBs. It is concluded that treatment of sporadically occurring ventricular ectopic activity in some patients may require attention to the neurophysiologic trigger rather than the cardiac target.
