Abstract
Seizures are a frequent sequela of impaired brain development and can be expected to affect more children with radiation-related brain damage than children without such damage. This report deals with the incidence and type of seizures among survivors prenatally exposed to the atomic bombing of Hiroshima and Nagasaki, and their association with specific stages of prenatal development at the time of irradiation. Fetal radiation dose was assumed to be equal to the dose to the maternal uterus. Seizures here include all references in the clinical record to "seizure," "epilepsy," or "convulsion." Histories of seizures were obtained at biennial routine clinical examinations starting at about the age of 2 years. These clinical records were used to classify seizures as febrile or unprovoked (without precipitating cause). No seizures were ascertained among subjects exposed 0-7 weeks after fertilization at doses higher than 0.10 Gy. The incidence of seizures was highest with irradiation at the eighth through the 15th week after fertilization among subjects with doses exceeding 0.10 Gy and was linearly related to the level of fetal exposure. This obtains for all seizures without regard to the presence of fever or precipitating causes, and for unprovoked seizures. When the 22 cases of severe mental retardation were excluded, the increase in seizures was only suggestively significant and only for unprovoked seizures. After exposure at later stages of development, there was no increase in recorded seizures.

Abstract
In a two-part study, the dose-response relationships of doxacurium chloride (BW A938U) were evaluated during general anesthesia maintained with commonly used anesthetic techniques. In part 1, cumulative dose-response methodology was used to establish the ED95 of doxacurium in 36 patients receiving 70% nitrous oxide and fentanyl, or 50% nitrous oxide and either 1.26% enflurane, 0.84% isoflurane, or 0.57% halothane anesthesia. Mechanomyographic response to train-of-four stimulation was used to monitor neuromuscular blockade. The peak effect of doxacurium following each 5 micrograms/kg incremental dose was noted and a log-probit dose-response curve was constructed for each individual patient. The median ED50s were 11 micrograms/kg, 6 micrograms/kg, 8 micrograms/kg, and 8 micrograms/kg for patients receiving fentanyl, enflurane, isoflurane, or halothane anesthesia, respectively. The median ED95s were 24 micrograms/kg, 14 micrograms/kg, 16 micrograms/kg, and 19 micrograms/kg for patients receiving fentanyl, enflurane, isoflurane, and halothane anesthesia, respectively. In part 2, 72 additional patients received a rapid single injection of the ED95 (n = 36) or 2 X ED95 (n = 36) of doxacurium appropriate for the administered anesthetic as estimated from part one of the study. Peak effects of the ED95 given as single injections correlated well with the results in part 1.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Non-ulcer dyspepsia (NUD) is a common complaint in which no systematic illness or organic proximal alimentary tract disease can be identified. The pathophysiology of NUD is probably heterogeneous. Eighty-two subjects with NUD were studied in a prospective randomized placebo-controlled study to assess the efficacy of colloidal bismuth subcitrate (CBS) chewable tablets at a dose of four tablets daily for 1 month. The role of Campylobacter pylori and associated histological gastritis was evaluated. Sixty-one percent of NUD patients had C. pylori in the gastric antrum compared with 25% of age-matched controls. C. pylori was associated with acute and chronic inflammation (P less than 0.001) in the antrum. C. pylori was cleared in 59% of CBS-treated subjects compared with only 4% placebo (P less than 0.05). Both acute and chronic inflammation improved in subjects cleared of bacteria. Clearance of C. pylori and histological improvement was associated with a significant decrease in symptoms. In C. pylori negative subjects improvement in symptoms occurred in both the placebo and active treatment groups. This study would suggest that C. pylori and associated histological gastritis may play a role in non-ulcer dyspepsia.

Abstract
To assess the effect of specific immunotherapy (IT) on the immediate and late asthmatic responses induced by cat or dog extract bronchial provocation testing, we studied seven cat-sensitive and six dog-sensitive subjects with asthma. Among the cat-sensitive subjects, two of three subjects displaying only an immediate asthmatic response before IT lost the response after 3 months of IT with cat extract, whereas only one of four subjects with the dual (immediate and late) asthmatic responses had ablation of such responses (no significance for the one-tailed test). Three subjects had worsening of the immediate response after IT. Among dog-sensitive subjects with asthma, three of five subjects with only an immediate response demonstrated an ablation of the immediate response, whereas the one subject who was the only subject with a dual response before IT lost the dual response after dog-extract IT (p value of 0.005 on one-tailed test). Immediate systemic side effects, including one episode of anaphylaxis, occurred on seven occasions of 326 injections with cat extract compared to only one episode of rhinitis of 289 injections with dog extract.

Abstract
We studied the effects of different procedures of blood collection and processing on quantification of apolipoprotein A-I (apoA-I) by radioimmunoassay. ApoA-II and apolipoproteins of low- and very-low-density lipoproteins did not cross react in the assay. Analytical recovery of apoA-I at different doses was complete. ApoA-I concentration in pooled human plasma was stable for as long as a year stored at -70 degrees C. Inter- and intra-assay CVs averaged 7% and 5%, respectively. We collected blood from 20 subjects into tubes containing EDTA alone or EDTA with antiproteolytic agents, then separated the plasma either immediately or after 3 h at 4 degrees C. We tested various formulations of antibacterial, antiproteolytic, and anti-oxidant agents added to plasma, measuring apoA-I concentrations either within 24 h of blood collection or after storage of plasma for 6 weeks at -70 degrees C. No significant difference in the concentrations of apoA-I was found in these specimens, regardless of the conditions studied. We conclude that addition of protective agents other than EDTA is not necessary during blood collection or specimen processing for reliable quantification of apoA-I in fresh or frozen human plasma.

Abstract
There is good evidence that the idiotypic network of the immune system can be implicated in the synthesis of pathogenic subsets of autoantibodies. The individual with systemic lupus erythematosus must have the immunoglobulin gene information which permits synthesis of those idiotypes, helper T populations which drive or select for the B cells producing them, and inadequate mechanisms to suppress those activated effector cells.

Abstract
The bone vitamin K-dependent protein osteocalcin has been suggested to play a role in bone resorption. By administering sodium warfarin to rats, it is possible to inhibit the vitamin K-dependent addition of the their gamma-carboxyglutamic acid residues to osteocalcin. This results in reduced amounts of osteocalcin bone, probably because devoid of the calcium-binding Gla residues, the protein no longer accumulates in bone. Preparations of bone obtained from rats treated with sodium warfarin for 6 weeks contained only 0.2% of normal levels of osteocalcin and were 90% reduced in the concentration of Gla. This bone could not be degraded by human monocytes in vitro as well as control bone (only 54% of control; P less than 0.003). Defects in the movement of cells to the bone were documented by phase contrast microscopy. Only 60% as many monocytes attached to the osteocalcin-depleted bone as to control bone in an in vitro attachment assay. These effects do not appear to be related to direct cellular toxicity. The degradation of bone in this in vitro system appears to be dependent on the osteocalcin content in matrix. This may result from defective movement of cells to bone and/or attachment to the bone.

Abstract
A prospective study of diaphragm users at the Family Planning Association of Victoria was undertaken. Despite the women being well motivated and instructed the pregnancy rate was high (24 per 100 woman years) and the continuation rate was only 35% at 12 months. Three-quarters of the women who became pregnant admitted that they did not use a diaphragm on every occasion. Therefore emphasis must be placed on the committed use of the diaphragm every time coitus occurs. Even so, the diaphragm does not appear to be a very safe method of contraception, and may be better suited to family spacing rather than as a method when high efficacy is required.

Abstract
We established an experimental animal model of the gastrointestinal colonization and systemic disease following oral challenge of type III group B streptococcal strain in 3-day-old newborn rats. Two type III group B streptococcal strains isolated from the cerebrospinal fluid of septic newborn infants produced colonization in 57-87% of the challenged animals and 13-31% of these colonized animals developed systemic disease. Using this new animal model, we evaluated the effect of orally administered human immune serum globulin on the colonization and systemic disease. This antiserum contained 21 micrograms/ml of type III group B streptococcal antibody of human IgG class. Animals fed with immune serum globulin developed significantly lower rates of colonization and systemic disease than those of control (albumin or saline) (23 versus 71%, p less than 0.001 for colonization; 7 versus 31%, p less than 0.05 for systemic disease). However, rates of the development of systemic disease among the colonized animals were not significantly different between the two groups (33 versus 43%, p greater than 0.1). These findings suggest that orally administered immune serum globulin is beneficial in the prevention of colonization and systemic disease in this rat model and that this protective effect of oral immune serum globulin occurs primarily at the mucosal level.

Abstract
A retrospective study of the outcome of postcoital intervention for the prevention of pregnancy in 201 women who attended the Victorian Family Planning Clinic from January 1982 to September 1983 is presented. Four pregnancies resulted from a total of 213 treatments performed. As a follow-up assessment could only be carried out in 107 cases, the rate of failure of postcoital treatment according to the recommended regimen was estimated as 4%. The reasons for attendance and the methods of contraception involved are considered in general, and the four cases in which the treatment failed are described in more detail. Recommendations are made with regard to subsequent contraception.

Abstract
The principles of family support and of social learning theories were applied to a feasibility study of working directly with family units in a health education program. Twenty-four Anglo, Black, and Mexican-American families of young elementary school children participated in a 3-month cardiovascular risk reduction education project which included eight weekly evening sessions designed to assist families to decrease the frequency of consumption of foods high in sodium and in saturated fats, and to increase the frequency of aerobic exercise. Statistically significant differences between randomly assigned treatment and control groups were noted for reported consumption of high sodium foods and of foods high in saturated fats. Experimental subjects gained more knowledge of factors influencing cardiovascular risk, even though the intervention was behaviorally, rather than cognitively, based. This method of health promotion is deserving of further study.

Abstract
As visualized by electron microscopy, RecA protein binds in a highly cooperative manner to single-stranded fd DNA in solutions of 0.01 M Tris (pH 7.5). The resulting nucleoprotein filament loops are 1.25 micrometers in length, have a fiber diameter of 12 nm and show an indication of a 4.5 nm repeat along the axis of the compact fibers. RecA binds to linear duplex fd DNA in solutions of 0.01 M Tris (pH 7.5) to yield chains of beads which, in the presence of Mg2+ and ATP, coalesce into smooth filaments with a length of 1.9 micrometers (the length of protein-free fd duplex DNA) and have a fiber diameter of 12 nm. In solutions containing Mg2+ and ATP-gamma-S, however, RecA binds to duplex DNA in a highly cooperative manner to yield rigid filaments 3.0 micrometers in length. These filaments are 12 nm in diameter and show a very clear 7.5 nm axial repeat. This extension of DNA to 150% of its usual length in the apparent absence of any single-stranded components suggests that the DNA helix must also be highly unwound and provides new insights into the mode of RecA action.

Abstract
We determined the ionic composition of faecal fluid from 13 patients with Crohn's disease limited to the colon, 10 with diffuse ulcerative colitis, and eight with ulcerative proctitis. The Crohn's and colitis groups had similar proportions of colon surface involved radiographically and similar 24 hour faecal weights. However, Crohn's patients' faecal fluid had arithmetically lower mean sodium and statistically lower mean chloride (34.8 mmol/l +/- 16.2 SD vs. 53.1 mmol/l +/- 23.1 SD) and higher potassium (49.2 mmol/l +/- 20.2 SD vs. 33.0 mmol/l +/- 13.8 SD) concentrations (p less than 0.05 for each) and much higher osmolality (487.1 mOsmol/kg +/- 87.1 SD vs. 341.1 mOsmol/kg +/- 88.9 SD, p less than 0.001). Separation of these patients using the faecal osmotic gap agreed with the clinical classification in 86% of cases. The diarrhoea of proctitis patients had a nearly normal ionic composition which was clearly distinguishable from that of diffuse colitis. These results suggest differences in the composition and perhaps the pathogenesis of the diarrhoea of Crohn's and ulcerative colitis. The composition of fluid may prove a useful, non-invasive method for classifying patients with inflammatory bowel disease and, in ulcerative colitis, determining the extent of the inflammatory process.

The metacontrast paradigm was exploited to study possible inhibitory interactions between sustained and transient channels. Variations and measures of target disinhibition or target recovery. The former type of target recovery is taken as evidence for interchannel sustained-on-transient inhibition; the latter, as evidence for intrachannel transient-on-transient inhibition.
