chlamydial infections. microbiological, clinical and diagnostic aspects.the agent of trachoma, originally regarded as a virus, was described by halberstadter and von prowacek in 1907. since then, studies on chlamydiae have shown that they are procaryocytic organisms that infect eucaryocytic cells as obligate intracellular parasites. infections caused by these pathogenic agents occur in a wide range of avian and mammalian species. chlamydiae are also responsible for several diseases in man, and there is a rapidly growing awareness of their public health significance. ...1979388102
participation of brain stimulation reward substrates in memory: anatomical and biochemical evidence.on the basis of the pioneering leads provided by james olds, brain stimulation reward has been shown to be a) derived from specific anatomical locations, b) influenced by psychotropic drugs, and c) functionally related to feeding behavior and sexual activity. these results recommend the view that it is worthwhile to understand, not necessarily the curious intracranial self-stimulation behavior itself, but the physiological function of the substrate revealed by the intracranial self-stimulation ( ...1979385350

formalinized chlamydia trachomatis organisms as antigen in the micro-immunofluorescence test.chlamydia trachomatis organisms grown in hela 229 cell cultures were purified and formalinized for use in the micro-immunofluorescence test. as test antigens, they were stable when stored unfrozen at 4 degrees c for a long period of time without loss of type specificity and sensitivity.1979389953
lung compliance and lung morphology following artificial ventilation in the premature and full-term rabbit neonate.rabbit neonates delivered on day 27--30 of gestation were subjected to intermittent positive pressure ventilation (ippv) for 60 min. tidal volume was standardized to 10 ml/kg, and the insufflation pressure required to maintain this tidal volume was recorded. the quasistatic compliance of the lung-thorax system, corrected for variations in body weight, was significantly lower in animals delivered on day 27--28 than in those delivered on day 29--30. immature animals with low lung-thorax complianc ...1979394314
comparison of various mccoy cell treatment procedures used for detection of chlamydia trachomatis.mccoy cells treated in six different ways, in addition to untreated cells, were compared to determine which gave rise to the largest number of chlamydia trachomatis inclusions when tested with a laboratory-passaged strain. the same batch of cells was treated by irradiation, preinoculation exposure to cytochalasin b or 5-iodo-2'-deoxyuridine, and postinoculation exposure to cycloheximide, hydrocortisone, or emetine. significantly more inclusions were always found in cells which had been treated w ...1979389948
etiology, manifestations and therapy of acute epididymitis: prospective study of 50 cases.there were 50 patients with acute epididymitis who were evaluated prospectively by history, examination and microbiologic studies, including cultures for aerobes, anaerobes, neisseria gonorrhoeae, chlamydia trachomatis and ureaplasma urealyticum. escherichia coli was the predominant pathogen isolated from the urine of men more than 35 years old, while chlamydia trachomatis and neisseria gonorrhoeae were the predominant pathogens isolated from the urethra of men less than 35 years old. the etiolo ...1979379366
social organization and food resources availability in primates: a socio-bioenergetic analysis of diet and disease hypotheses.data obtained during a field study of two species of nonhuman primates (alouatta villosa and ateles geoffroyi) living in the tikal national park in guatemala are used to suggest an answer to the question: to what extent is the existence of a particular form of social organization (group size, structure, and composition) an indication of the amount of energy in the form of food resources available to animals in a particular habitat? seven researchers working in teams spent 2,318 hours in the fiel ...1977403771
triple tetracycline (deteclo) in the treatment of chlamydial infection of the female genital tract.the efficacy of treating genital chlamydia in women using deteclo 300 mg twice daily for seven and 21 days has been studied. forty-four patients were treated for seven days and 20 for 21 days. seven days of treatment was as effective in eliminating chlamydia trachomatis from the female genital tract as 21 days. the reproducibility of the technique of isolation of c. trachomatis was assessed by delaying treatment in 10 patients for up to 156 days and find c. trachomatis still present.1977403996

human plasma angiotensinogen: a review of purification procedures.the current status of the purification and characterization of human angiotensinogen is reviewed. one problem encountered in the past has been the copurification of a protein with similar porperties. this protein has tentatively been designated alanine-protein. an efficient separation of angiotensinogen and alanine-protein was obtained on a zinc chelate column. alanine-protein has been purified and its amino acid and carbohydrate composition determined. the cooh-terminal amino acid and the nh2-t ...1979390363
urethritis in white men--a microbiological appraisal.the incidence of infections with neisseria gonorrhoeae, chlamydia trachomatis and mycoplasmas has been assessed in white men with urethritis who were attending a johannesburg clinic for sexually transmitted diseases. infection with n. gonorrhoeae was demonstrated in 54% of 212 patients with urethritis. c. trachomatis was isolated from 37% of patients with non-gonococcal urethritis, and from 25% with proven gonococcal infection. although t-mycoplasmas were isolated significantly more often from p ...1977406683
failure of serology in diagnosing chlamydial infections of the female genital tract.chlamydia trachomatis was recoved from 20% (36/180) of women attending a venereal disease clinic. all infected women had chlamydial antibodies in their serum and cervical secretions. however, the background rates of chlamydial antibody in chlamydia-negative women were very high. measurement of antibodies in serum (complement fixation or immunoglobulin g [igg] and igm by microimmunofluorescence) or cervical secretion (igg, igm, iga or secretory iga classes) did not result in predictive values of ...1979397220
diagnosis and treatment of acute salpingitis.acute salpingitis is one of the most common acute gynecologic diseases and occurs in approximately 750,000 women each year in the united states. use of laparoscopy to confirm the diagnosis of acute salpingitis has shown that the signs and symptoms classically ascribed to this disease are not specific to it. fever, leukocytosis, elevated esr and adnexal masses or swelling are not necessary to make a diagnosis of acute salpingitis. lower abdominal pain and adnexal tenderness are the most consisten ...1977406388

isolation of chlamydia trachomatis from eye secretion (tears).shedding of chlamydia trachomatis in the eye secretion (tears) of patients with either hyperendemic trachoma or paratrachoma was studied. the method of collection of eye secretion with cellulose sponges is proved to be simple, faster, and more practicable and yielded a higher rate of chlamydial isolation than aspiration. the chlamydial isolation rates in eye secretion in chlamydia-positive paratrachoma patients in london or trachoma patients in iran was 84 and 49% respectively. it was found that ...1979435443
arrays of hemispheric surface projections on chlamydia psittaci and chlamydia trachomatis observed by scanning electron microscopy.scanning microscopy of two strains of chlamydia psittaci and four strains of chlamydia trachomatis representative of the wide diversity in origin and behavior of members of the genus revealed patches of regular arrays of hemispheric projections on the surfaces of elementary bodies of all six strains. these distinctive and perhaps unique surface structure are probably present in all populations of chlamydiae.1979438131
purulent ocular discharge in neonates: significance of chlamydia trachomatis.we obtained cultures for bacteria and chlamydiae from 100 infants with conjunctivitis that began during the first month of life. sixty-nine infants were evaluated during well-child visits (group a); 31 were seen specifically for the ocular discharge (group b). potentially pathogenic bacteria, predominantly staphylococcus aureus, were cultured from one third of the infants in each group. chlamydia trachomatis was recovered from three infants (4%) in group a and from ten (32%) in group b. three in ...1979440875
infection with chlamydia trachomatis: involvement of multiple anatomic sites in neonates.in a study of infection due to chlamydia trachomatis in infants, chlamydiae were recovered not only from the conjunctiva and respiratory tract but also from the vagina and rectum. the timing of recovery suggested that the vagina and conjunctivae are exposed to chlamydiae at birth and that pneumonia and gastrointestinal infection occur later. sampling of the rectum may be a useful procedure for the diagnosis of chlamydial disease in infants.1979438536
clinical characteristics of the afebrile pneumonia associated with chlamydia trachomatis infection in infants less than 6 months of age.respiratory tract colonization with chlamydia trachomatis commonly occurs in natally acquired chlamydial infection and is sometimes associated with a chronic, afebrile pneumonia that has relatively distinctive clinical characteristics. to further define the frequency and clinical characteristics of lower respiratory tract disease associated with c trachomatis, we grouped 56 infants aged less than 6 months with afebrile pneumonia according to nasopharyngeal shedding of chlamydia and viruses and c ...1979440806
treatment of chlamydial pneumonia of infancy.infants with untreated chlamydial pneumonia shed chlamydia trachomatis and are symptomatic for may weeks. we used sulfisoxazole, 150 mg/kg/day, or erythromycin ethyl succinate, 40 mg/kg/day, for approximately 14 days to treat 32 patients with chlamydial pneumonia of infancy, and observed them for nasopharyngeal shedding of c trachomatis and changing clinical status. all infants stopped shedding chlamydiae soon after treatment was started. after treatment, three of the 25 infants tested again bec ...1979440807
activity of oral amoxicillin, ampicillin, and oxytetracycline against infection with chlamydia trachomatis in mice.the effects in mice of oral treatment with amoxicillin, ampicillin, and oxytetracycline against an otherwise lethal intranasal infection with chlamydia trachomatis (mouse pneumonitis) were studied. when treatment was started 30 min after infection and continued once daily thereafter for a total of seven treatments, the mean protective doses of amoxicillin, ampicillin, and oxytetracycline were 9.5, greater than 50, and 31.3 mg/kg, respectively. if 14 oral treatments were given, these values were ...1979448198
chlamydia trachomatis in women: antibody in cervical secretions as a possible indicator of genital infection.one hundred eighty-five women college students were examined for genital infection with chlamydia trachomatis. this organism was isolated from nine (5%) of the 185 women. antibody was demonstrated in the genital secretions of 26 (14%) and in the serum of 70 (38%) of the women. none of the sexually inexperienced women was infected. among those sexually experienced, the prevalence of isolation of c. trachomatis and of detection of local antibodies in cervical secretions and serum antibodies to c. ...1979448189
[various mechanisms of cardiogenic shock under experimental conditions].study of the mechanisms of compensation derangement in cardiogenic shock in 70 anesthetized and nonanesthetized dogs irrespective of the type of its course showed that extracardiac shifts are of essential importance. in "fulgurating" shock, marked cardiac disorders may be aggravated by stimuli induced by hyperactive humoral and vascular (peripheral) reactions. in cardiogenic shock of a longer duration, the extracardiac mechanisms of decompensation are usually manifested by disorders of periphera ...1979459217

effect of oxipurinol and allopurinol riboside on whewellite crystallization: in vitro and in vivo observations.solubility measurements, seeded crystal growth kinetics, solution depletion adsorption studies, nucleation observations, zeta potential measurements, and measurements of in vivo intrarenal crystallization all failed to show that either oxipurinol or allopurinol riboside interacts with calcium, oxalate, or whewellite (cac2o4.h2o) at concentrations expected in therapeutic situations. we conclude that at therapeutically expected concentrations, oxipurinol and allopurinol riboside do not affect crys ...1979500322
brain adenylate cyclase activation in the jaundiced rat.adenylate cyclase responses of brain cortex and neostriatum to noradrenaline and dopamine are increased in rats with jaundice in proportion to its severity. in comparing the situation with uraemia, the relevance of phenols has to be considered.1979499399

the complete amino acid sequence of actins from bovine aorta, bovine heart, bovine fast skeletal muscle, and rabbit slow skeletal muscle. a protein-chemical analysis of muscle actin differentiation.complete amino acid sequences for four mammalian muscle actins are reported: bovine skeletal muscle actin, bovine cardiac actin, the major component of bovine aorta actin, and rabbit slow skeletal muscle actin. the number of different actins in a higher mammal for which full amino acid sequences are now available is therefore increased from two to five. screening of different smooth muscle tissues revealed in addition to the aorta type actin a second smooth muscle actin, which appears very simil ...1979499690
wheat germ agglutinin blockage of chlamydial attachment sites: antagonism by n-acetyl-d-glucosamine.addition of 2 to 10 micrograms of wheat germ agglutinin (wga), a lectin from triticum vulgaris specific for n-acetyl-d-glucosamine, per ml to suspensions of mouse fibroblasts (l cells) blocked the attachment of 14c-labeled chlamydia psittaci 6bc to the l-cell surface. wga and strain 6bc competed for similar sites on l cells, but once bound, one was not replaced by the other. n-acetyl-d-glucosamine, but not other monosaccharides of related structure, antagonized the blocking action of wga. lectin ...1979500195

major elements in milk of the west african dwarf goats as affected by stage of lactation.tweove adult west african dwarf (fouta djallon) does, about 2 years old and weighing from 25 to 28 kg were kept for lactation studies lasting two 19-week periods. during these periods the does were hand-milked twice daily and the daily samples were bulked for each animal for subsequent analysis. the results showed that the colostrum was much richer in its content (g/kg) of na 1.44 +/- 0.17, k 3.38 +/- 0.22 and cl 4.83 +/- 0.29 than the mature milk which contained (g/kg) na 0.65 +/- 0.09, k 1.57 ...1979500883
high level of human growth hormone (hgh) in cerebrospinal fluid patients with pituitary tumors.six patients with suprasellar extension of pituitary hgh-secreting tumors showed the cerebrospinal fluid (csf) content in human growth hormone (hgh) to be very high, i.e. 164.3 +/- muu/ml (mean +/- sem) (range 8.4--413.8 muu/ml) as compared to ten patients with uncomplicated acromegaly whose values were 50-fold lower, i.e. 3.4 +/- 0.5 muu/ml (range 0.6--7.0 muu/ml), and nine patients with suprasellar extension of other pituitary tumors, showing also low levels of hgh in the csf, i.e. 2.9 +/- 0.8 ...1979504962

cold acclimation in the secretory responses of the isolated exocrine pancreas of the rat.1. the secretory function of the isolated and perfused exocrine pancreas has been studied in the course of cold acclimation in rats that were fed at an ambient temperature of 1 degrees c in an artificial climatic room.2. a series of experiments was carried out in early autumn (autumn series). the sums of the outputs of protein, amylase, zymogen protease, lipase, and juice flow in samples collected for a total of 30 min during and after 5 min stimulation with different concentrations of cholecyst ...1979501617
vaginal oxytetracycline concentrations.although tetracycline preparations are widely used in departments of genitourinary medicine, or sexually transmitted diseases clinics, little is known of the concentrations of these preparations in genital secretions. for this reason a microbiological method was used for estimating oxytetracycline concentrations in vaginal secretions. these concentrations varied from 0.6 to 6.5 microgram/ml in 19 women who had had sexual contact with a man with non-specific urethritis and who were taking oxytetr ...1979509190
