Data from the National Congenital Rubella Surveillance Programme showed that 44% of children with congenital rubella reported to the programme were born to primiparae. This high proportion is thought to be due to the fact that there was a two-fold increase in the rate of abortion for rubella in pregnancy ...

A haemagglutination inhibition test, developed specifically for primates, diagnoses early pregnancy in the chimpanzee, gorilla, orang-utan and baboon. The test was sensitive and reacted positively when the concentration of gonadotrophin in urine was equivalent to 0.03 i.u. human chorionic gonadotrophin per ml. This degree of sensitivity and the certitude that ...

During a period of six years 7,555 bovine sera, 421 canine sera, 251 porcine sera and 135 equine sera were tested for agglutinins to Leptospira interrogans serotypes canicola, grippotyphosa, hardjo, icterohemorrhagiae, pomona and sejroe. The bovine sera reacted predominantly with hardjo and/or sejroe at a rate of 15% compared to ...

The adsorptive properties of four charcoals have been examined in relation to their value as adsorbents in filters attached to an anaesthetic trolley. Data for four anaesthetics have been obtained. The test conditions (flow rate, concentration, humidity) were those relevant to the application, and the effect of variation of these ...

The Subhuman Primate Pregnancy Test kit was used for diagnosis of pregnancy in 15 baboons. This hemagglutination inhibition test for urinary chorionic gonadotropin accurately indicated conception by positive responses in 106 of 109 specimens collected between 17 and 30 da after the estimated day of fertilization. Maximum hormone levels were ...

Erections were measured in 20 male homosexual subjects under three instructional conditions and within three stimulus modalities. The three conditions were arousal (e.g., imagine yourself involved and get aroused), suppression (e.g., imagine yourself involved bu suppress erection responses), and rearousal (e.g., imagine yourself involved and get aroused). The three stimulus ...

A case of subclinical rubella reinfection during pregnancy with serologic findings in the offspring initially led to an erroneous diagnosis of fetal infection. Laboratory diagnosis of congenital rubella infection, based on finding hemagglutination-inhibition (HI) activity in immunoglobulin M (IgM) fractions of newborn's serum after sucrose gradient fractionation, was questioned when ...

Results of routine rubella hemagglutination-inhibiting antibody tests on 39,005 serum samples showed that 9-5% of women of childbearing age in the Leeds region were seronegative, and a further 9-2% had low antibody titres of 1/8 or 1/16. Since routine rubella vaccination of schoolgirls began in 1970 the frequency of seronegative ...

An experimental chick hatcher designed to filter recycled ventilation air was tested for its effectiveness in reducing the number of viable airborne microorganisms. Chicks in a filtered hatcher and a control hatcher (no filter) were artificially contaminated with Serratia marcescens as ventilation air was recycled in the hatchers for twelve ...

Sixty patients with less than six weeks amenorrhoea were examined by ultrasonic "B" scanning for the detection of pregnancy. The results were compared with those obtained by histological examination of the aspirate after the patient had undergone menstrual regulation by vacuum aspiration of the uterine contents. The overall accuracy was ...

A mass airflow cabinet for handling and housing of laboratory rodents has been developed and tested. The unit consists of a high-efficiency particulate air filter and uniform distribution of air at a vertical velocity of 19 cm per s. Animals are maintained without bedding in mesh-bottomed cages that rest on ...

To test the hypothesis that leukaemia may follow virus infection in pregnancy an analysis was made of deaths which occurred in a cohort of children born in 1951 and 1952 after pregnancies in which the mothers suffered virus infections-chickenpox or mumps at any stage of gestation or rubella in the ...

The clinical, epidemiologic and laboratory information available in the Johns Hopkins Rubella Study forms the basis for discussion of the pathogenesis of congenital rubella, the varied clinical characteristics of the phenotype and the substantial risk of fetal loss and abnormality when maternal rubella occurs in the first half of pregnancy.

One hundred and sixty-three patients with bacteriuria in pregnancy were treated with a single dose of antibiotic. Four regimens were used: sulfadoxine (sulphormethoxine) 2 g., sulfametopyrazine 2 g., streptomycin 1 g., and a combination of sulfametopyrazine 2 g. and streptomycin 1 g. The highest cure rate of 77% was achieved ...

In 45 patients with rubella-like illnesses during pregnancy serological tests showed that the clinical diagnosis had been accurate in only 20. Since only 16 of these patients had presented for laboratory investigations within a week of the onset of symptoms, the value of haemagglutination-inhibition tests was considerably reduced; the diagnosis ...

This article provides information about hyperemesis gravidarum, a severe and intractable nausea and vomiting in pregnancy, and is made available on the Web by eMedicine, the largest and most current clinical knowledge base available to physicians and health professionals. This peer reviewed article provides information about the pathophysiology and frequency ...

BACKGROUND: In 1941, a Sydney ophthalmologist, Norman McAlister Gregg, correctly identified the link between congenital cataracts in infants and maternal rubella early in pregnancy. Fifty of Gregg's subjects with congenital rubella, born in 1939-1944, were reviewed in 1967 and again in 1991. We reviewed this cohort in 2000-2001, 60 years ...

Rosenblum, E. D. (The University of Texas, Dallas), and Sue Tyrone. Serology, density, and morphology of staphylococcal phages. J. Bacteriol. 88:1737-1742. 1964.-A correlation between serology, buoyant density, and morphology has been demonstrated for six serological groups of staphylococcal phages. Four morphological types have been observed and represent the following serological ...

Experience with a latex agglutination-inhibition slide test for human chorionic gonadotrophin which allows pregnancy to be diagnosed in three minutes is described. Among 350 tests performed, 115 were in patients who presented with some complication of a presumed pregnancy, and 132 patients presented diagnostic problems in which pregnancy was to ...

Simultaneous pregnancy tests were run on duplicate specimens of urine by the Friedman method and the latex flocculation method on 329 patients. Clinical correlation was available in 245 of these patients. The latex test had a sensitivity of 77 per cent and a specificity of 92 per cent in the ...

The reactions for the diagnosis of pregnancy by the use of urine from patients who are receiving tranquilizing drugs of the phenothiazine group have given false positive results when performed in the North American frog Rana pipiens. Such false positive reactions are not obtained when the South American toad Bufo ...
