The patient who has clinical jaundice, abnormal results on liver function tests, or both presents a difficult diagnostic challenge. Many infectious diseases affect the liver, and the extent of involvement determines the degree of clinically apparent jaundice. Some diseases that affect the liver minimally cause no jaundice at all. An important clue to the cause of the disorder is the pattern of abnormal results on liver function tests. Increased alkaline phosphatase predominates with Q fever, secondary or tertiary syphilis, clonorchiasis, and hepatic candidiasis, while elevated levels of serum transaminases characterize viral hepatitis, leptospirosis, mononucleosis syndromes, legionnaires' disease, typhoid fever, toxic shock syndrome, and yellow fever. Increases in serum bilirubin are typical with jaundice caused by clostridial myelonecrosis, severe bacterial sepsis, and relapsing fever (borreliosis). These findings together with the patient's history, physical findings, and basic laboratory tests provide a presumptive diagnosis in most cases.

We developed a competitive, enzyme-linked immunosorbent assay for the quantitation of toxic shock syndrome toxin 1 (TSST-1). Polyvalent immunoglobulin G from immunized rabbits was used as the capture antibody, and alkaline phosphatase conjugated to purified toxin served as the indicator enzyme. A standard curve was generated with each experiment, from which the concentration of toxin in culture supernatants was extrapolated. The assay was useful for determining toxin concentrations of 0.03 to 0.5 micrograms/ml, which is a substantial, practical improvement over immunodiffusion methods. Staphylococcal enterotoxins A through E were not significantly cross-reactive in the assay, and staphylococcal protein A did not interfere with quantitation of TSST-1. By testing a variety of staphylococcal strains, we found 100% concordance between toxin determinations made with our assay and those made by the investigators from whom the strains were obtained. The competitive, enzyme-linked immunosorbent assay is a highly reproducible, inexpensive means of determining TSST-1 concentrations and may have broad applicability in the field of toxic shock research.

Cefmenoxime was evaluated in an open trial consisting of 41 patients. Forty infections in 36 patients could be evaluated. Thirteen patients had pyelonephritis due to Escherichia coli (two bacteremic), Pseudomonas aeruginosa, Klebsiella pneumoniae, or Streptococcus faecalis; all improved and 12 of 13 were clinically cured, but one relapse (S. faecalis) occurred at two weeks. Six patients with cystitis due to E. coli, Citrobacter freundii, Serratia marcescens, P. aeruginosa, or S. faecalis all improved, but relapse or reinfection, or both, occurred in five due to P. aeruginosa, S. faecalis, C. fruendii, or E. coli. Neurogenic bladder or other complications were present in five of 13 patients with pyelonephritis and five of six with cystitis. Ten patients with pneumonia and one with tracheobronchitis due to Hemophilus influenzae, S. pneumoniae, S. agalactiae, or Neisseria meningitidis all improved and seven had resolution without relapse, but P. aeruginosa emerged in two patients, one of whom died. Eight soft tissue infections due to Staphylococcus aureus, Peptococcus prevotti, Streptococcus species, or infections of mixed origin resolved in six. Sterility of blood cultures was obtained in one patient with endocarditis due to S. anginosus, but other therapy was substituted. Clinical resolution of the toxic shock syndrome and subsequent negative endocervical cultures for S. aureus occurred in one. Granulocytopenia of unverified cause in four (with less than 1,500 mm3) and two (with less than 2,000 mm3) was reversible. Headache during treatment occurred in six patients and a possible disulfiram-like effect in three. Elevations of serum glutamic oxalacetic transaminase and alkaline phosphatase occurred in five, Coombs' positivity in two, and diarrhea in three. Clinical efficacy of cefmenoxime was significant. Possible side effects require further study.

The present investigation was undertaken to examine the characteristics of purified toxic shock syndrome toxin-1 (staphylococcal enterotoxin F) given intravenously to dwarf goats (dose, 0.02 to 20 micrograms kg-1). Rectal temperature, heart rate, rumen motility, plasma zinc and iron concentrations, and certain other blood biochemical and hematological values were studied and compared with the changes seen after intravenous administration of staphylococcal enterotoxin B (dose, 0.02 to 0.5 micrograms kg-1). Similar changes such as fever, tachycardia, inhibition of rumen contractions, drop in plasma zinc and iron concentrations, lymphopenia, and a decrease in serum alkaline phosphatase activity were observed. In contrast to the effects of toxic shock syndrome toxin-1, staphylococcal enterotoxin B induced colic, watery diarrhea with pseudomembranes, hemoconcentration, and a more pronounced increase in blood urea nitrogen. The results obtained demonstrate that (i) in the goat staphylococcal enterotoxin B is much more potent than toxic shock syndrome toxin-1 and (ii) the goat is a useful model to study the gastro-intestinal effects caused by staphylococcal enterotoxin B. The present finding that no clear relationship could be found between the temperature response and the alterations in zinc and iron levels in plasma support the theory that the febrile reactions and the changes in plasma trace metals are mediated by different polypeptides released by activated macrophages.

We investigated the effects of Toki-shakuyaku-san (TSS, Tang-Kuei-Shao-Yao-San in Chinese), Japanese traditional herbal medicine, on the nervous and immune systems in ovariectomized mice as a climacteric disorder model. Female C57BL/6 mice were ovariectomized (OVX) and TSS was given daily through the drinking water for either 10 or 20 days from the day after ovariectomy. After completion of experimental sessions, animals were sacrificed and specific brain regions were assayed for choline acetyltransferase (ChAT) activity and norepinephrine contents. The mitogenic activities, alkaline phosphatase activity and 3-(4, 5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H terazolium bromide (MTT) activity, in splenic lymphocytes has also measured. Furthermore, the effects of TSS on learning and memory ability were studied by the step-through type passive avoidance test. As the results, the administration of TSS significantly suppressed the decrease of ChAT activity in the cerebral cortex (CC) and the dorsal hippocampus (DH) of ovariectomized mice at 10 days after ovariectomy, however no significant effect was observed at 20 days after ovariectomy. Norepinephrine contents in OVX group were decreased at 10 and 20 days after ovariectomy in the CC and the ventral hippocampus (VH). The administration of TSS significantly suppressed the decrease of norepinephrine contents at 20 days after ovariectomy. The mitogenic activities of lymphocyte in spleen were increased at 10 days after ovariectomy, and decreased at 20 days after ovariectomy. However, the suppression of these changes was observed in the group given TSS. The mean latent period was also shortened in the passive avoidance test in the OVX group, but TSS treated group improved mean latency. From these observations, it is inferred that administration of TSS brings on the synthesis of acetylcholine and norepinephrine in the CC and hippocampus, and may improve the memory related behavior and the abnormalities in lymphocytes in the models of the climacteric disorder.

Staphylococcus aureus causes a wide range of infections in humans, ranging from superficial skin infections to the more serious toxin-mediated diseases such as toxic shock syndrome. Owing to the increasing resistance of this bacterium to a wide range of antibiotics, the need to determine the virulence factors involved in infection is becoming more important as these molecules are potential therapeutic targets. In this study, we have screened for putative exported proteins from S. aureus on the basis that these proteins are likely to be the first point of contact between the bacterium and host during infection. We have constructed gene fusions between S. aureus DNA and a truncated version of the Escherichia coli phoA gene, and we report on the characterization of the recombinants exhibiting alkaline phosphatase activity. As well as known S. aureus proteins, we have identified a number of putative open reading frames that encode proteins similar to those from nonstaphylococcal species and also unique proteins that do not have any homologues on the current databases.
