The lipopolysaccharide molecule consists of three parts: LIPID A, core polysaccharide, and O-specific chains (O ANTIGENS). When derived from Escherichia coli, lipopolysaccharides serve as polyclonal B-cell mitogens commonly used in laboratory immunology. (From Dorland, 28th ed)

Infections of the brain caused by arthropod-borne viruses (i.e., arboviruses) primarily from the families TOGAVIRIDAE; FLAVIVIRIDAE; BUNYAVIRIDAE; REOVIRIDAE; and RHABDOVIRIDAE. Life cycles of these viruses are characterized by ZOONOSES, with birds and lower mammals serving as intermediate hosts. The virus is transmitted to humans by the bite of mosquitoes (CULICIDAE) or TICKS. Clinical manifestations include fever, headache, alterations of mentation, focal neurologic deficits, and COMA.

In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive.

Features of the immune response to DNA in mice. I. Genetic control. (1/9010)

The genetic control of the immune response to DNA was studied in various strains of mice F1 hybrids and corresponding back-crosses immunized with single stranded DNA complexed to methylated bovine serum albumin. Anti-DNA antibody response was measured by radioimmuno-logical technique. High responder, low responder, and intermediate responder strains were found and the ability to respond to DNA was characterized as a dominant genetic trait which is not linked to the major locus of histocompatibility. Studies in back-crosses suggested that this immune response is under multigenic control. High responder mice produce both anti-double stranded DNA and anti-single stranded DNA 7S and 19S antibodies, while low responder mice produce mainly anti-single stranded DNA 19S antibodies.  (+info)

Skeletal muscle type ryanodine receptor is involved in calcium signaling in human B lymphocytes. (2/9010)

The regulation of intracellular free Ca2+ concentration ([Ca2+]i) in B cells remains poorly understood and is presently explained almost solely by inositol 1,4,5-triphosphate (IP3)-mediated Ca2+ release, followed by activation of a store-operated channel mechanism. In fact, there are reports indicating that IP3 production does not always correlate with the magnitude of Ca2+ release. We demonstrate here that human B cells express a ryanodine receptor (RYR) that functions as a Ca2+ release channel during the B cell antigen receptor (BCR)-stimulated Ca2+ signaling process. Immunoblotting studies showed that both human primary CD19(+) B and DAKIKI cells express a 565-kDa immunoreactive protein that is indistinguishable in molecular size and immunoreactivity from the RYR. Selective reverse transcription-polymerase chain reaction, restriction fragment length polymorphism, and sequencing of cloned cDNA indicated that the major isoform of the RYR expressed in primary CD19(+) B and DAKIKI cells is identical to the skeletal muscle type (RYR1). Saturation analysis of [3H]ryanodine binding yielded Bmax = 150 fmol/mg of protein and Kd = 110 nM in DAKIKI cells. In fluo-3-loaded CD19(+) B and DAKIKI cells, 4-chloro-m-cresol, a potent activator of Ca2+ release mediated by the ryanodine-sensitive Ca2+ release channel, induced Ca2+ release in a dose-dependent and ryanodine-sensitive fashion. Furthermore, BCR-mediated Ca2+ release in CD19(+) B cells was significantly altered by 4-chloro-m-cresol and ryanodine. These results indicate that RYR1 functions as a Ca2+ release channel during BCR-stimulated Ca2+ signaling and suggest that complex Ca2+ signals that control the cellular activities of B cells may be generated by cooperation of the IP3 receptor and RYR1.  (+info)

Human triclonal anti-IgG gammopathy. I. Iso-electric focusing characteristics of the IgG, IgA and IgM anti-IgG and their heavy and light chains. (3/9010)

Human IgG, IgA and IgM anti-IgG autoantibodies have been isolated from the serum of an individual with Felty's syndrome. These were initially noted as soluble circulating serum complexes by analytical ultracentrifugation. Isolation was accomplished by solid phase immunoadsorption and each of the three antibody populations obtained was shown to be of restricted heterogeneity by liquid and polyacrylamide gel electrofocussing methods. Type kappa light chains were obtained from each protein. Co-isoelectric focusing experiments of all possible pairs of these light chains showed them to have identical net charge characteristics. Heavy chains obtained from each protein were also monoclonal and of differing isoelectric point. The availability of this serum provides a human model with which to study the changes which may occur in autoantibodies during the autoimmune response.  (+info)

Pre-mRNA splicing of IgM exons M1 and M2 is directed by a juxtaposed splicing enhancer and inhibitor. (4/9010)

Splicing of certain pre-mRNA introns is dependent on an enhancer element, which is typically purine-rich. It is generally thought that enhancers increase the use of suboptimal splicing signals, and one specific proposal is that enhancers stabilize binding of U2AF65 to weak polypyrimidine (Py) tracts. Here, we test this model using an IgM pre-mRNA substrate, which contains a well-characterized enhancer. Although the enhancer was required for in vitro splicing, we found it had no effect on U2AF65 binding. Unexpectedly, replacement of the natural IgM Py tract, branchpoint, and 5' splice site with consensus splicing signals did not circumvent the enhancer requirement. These observations led us to identify a novel regulatory element within the IgM M2 exon that acts as a splicing inhibitor; removal of the inhibitor enabled splicing to occur in the absence of the enhancer. The IgM M2 splicing inhibitor is evolutionarily conserved, can inhibit the activity of an unrelated, constitutively spliced pre-mRNA, and acts by repressing splicing complex assembly. Interestingly, the inhibitor itself forms an ATP-dependent complex that contains U2 snRNP. We conclude that splicing of IgM exons M1 and M2 is directed by two juxtaposed regulatory elements-an enhancer and an inhibitor-and that a primary function of the enhancer is to counteract the inhibitor.  (+info)

Innate and acquired humoral immunities to influenza virus are mediated by distinct arms of the immune system. (5/9010)

"Natural" Igs, mainly IgM, comprise part of the innate immune system present in healthy individuals, including antigen-free mice. These Igs are thought to delay pathogenicity of infecting agents until antigen-induced high affinity Igs of all isotypes are produced. Previous studies suggested that the acquired humoral response arises directly from the innate response, i.e., that B cells expressing natural IgM, upon antigen encounter, differentiate to give rise both to cells that secrete high amounts of IgM and to cells that undergo affinity maturation and isotype switching. However, by using a murine model of influenza virus infection, we demonstrate here that the B cells that produce natural antiviral IgM neither increase their IgM production nor undergo isotype switching to IgG2a in response to the infection. These cells are distinct from the B cells that produce the antiviral response after encounter with the pathogen. Our data therefore demonstrate that the innate and the acquired humoral immunities to influenza virus are separate effector arms of the immune system and that antigen exposure per se is not sufficient to increase natural antibody production.  (+info)

Dietary effect of EPA-rich and DHA-rich fish oils on the immune function of Sprague-Dawley rats. (6/9010)

The dietary effect of fish oils (FOs) rich in eicosapentaenoic acid (EPA) or docosahexaenoic acid (DHA) on the immune function of Sprague-Dawley rats was compared with that of safflower oil. After 3 weeks of feeding at the 10% level of a dietary fat, the IgG and IgM production by splenocytes and IgG production by mesenteric lymph node (MLN) lymphocytes were significantly higher in the FO-fed rats, while no significant difference was found in IgA or IgE productivity by both the spleen and MLN lymphocytes. In the FO-fed rats, peritoneal exudate cells released a lower amount of LTB4, reflecting their lower arachidonic acid level, and a higher amount of LTB5, reflecting their higher EPA level in phospholipids. On these EPA-rich FO exerted a stronger effect than DHA-rich FO immune functions.  (+info)

Immunodeficiency due to a unique protracted developmental delay in the B-cell lineage. (7/9010)

A unique immune deficiency in a 24-month-old male characterized by a transient but protracted developmental delay in the B-cell lineage is reported. Significant deficiencies in the number of B cells in the blood, the concentrations of immunoglobulins in the serum, and the titers of antibodies to T-dependent and T-independent antigens resolved spontaneously by the age of 39 months in a sequence that duplicated the normal development of the B-cell lineage: blood B cells followed by immunoglobulin M (IgM), IgG, IgA, and specific IgG antibodies to T-independent antigens (pneumococcal polysaccharides). Because of the sequence of recovery, the disorder could have been confused with other defects in humoral immunity, depending on when in the course of disease immunologic studies were conducted. Investigations of X-chromosome polymorphisms suggested that the disorder was not X linked in that the mother appeared to have identical X chromosomes. An autosomal recessive disorder involving a gene that controls B-cell development and maturation seems more likely. In summary, this case appears to be a novel protracted delay in the development of the B-cell lineage, possibly due to an autosomal recessive genetic defect.  (+info)

Predominant immunoglobulin A response to phase II antigen of Coxiella burnetii in acute Q fever. (8/9010)

Diagnosis of acute Q fever is usually confirmed by serology, on the basis of anti-phase II antigen immunoglobulin M (IgM) titers of >/=1:50 and IgG titers of >/=1:200. Phase I antibodies, especially IgG and IgA, are predominant in chronic forms of the disease. However, between January 1982 and June 1998, we observed anti-phase II antigen IgA titers of >/=1:200 as the sole or main antibody response in 10 of 1,034 (0.96%) patients with acute Q fever for whom information was available. In order to determine whether specific epidemiological or clinical factors were associated with these serological profiles, we conducted a retrospective case-control study that included completion of a standardized questionnaire, which was given to 40 matched controls who also suffered from acute Q fever. The mean age of patients with elevated phase II IgA titers was significantly higher than that usually observed for patients with acute Q fever (P = 0.026); the patients were also more likely than controls to live in rural areas (P = 0.026) and to have increased levels of transaminase in blood (P = 0.03). Elevated IgA titers are usually associated with chronic Q fever and are directed mainly at phase I antigens. Although the significance of our findings is unexplained, we herein emphasize the fact that IgA antibodies are not specific for chronic forms of Q fever and that they may occasionally be observed in patients with acute disease. Moreover, as such antibody profiles may not be determined by most laboratories, which test only for total antibody titers to phase I and II antigens, the three isotype-specific Ig titers should be determined as the first step in diagnosing Q fever.  (+info)

Evidence shows that psychosocial factors are associated with immunoglobulin G response to medical vaccinations. As yet, there are no reports of whether the earlier immunoglobulin M response is similarly susceptible. This study examined the association between psychological stress, social support and the immunoglobulin M response to vaccination with pneumococcal capsular polysaccharides. Stressful life events in the previous year and customary social support were measured by standard questionnaires at baseline in 74 healthy students (41 females). The response to five common pneumococcal serotypes was assessed at baseline and five-days following vaccination. Social support, particularly tangible social support, was positively associated with the antibody response to two of five serotypes, after controlling for baseline titre. These associations survived adjustment for demographics and health behaviours. There was no association between life events stress and immunoglobulin M response. It appears ...
Abstract An enzyme-linked immunosorbent assay (ELISA) was developed to detect different hantavirus antigens in cell culture; i.e. Puumala (PUU), Hantaan (HTN), and Dobrava (DOB) viruses. The assay was based on binding human serum immunoglobulin M (IgM) antibodies to the solid phase by use of goat anti-IgM antibodies. The captured IgM antibodies were present in the acute phase serum from two patients: one infected in Sweden and the other in Bosnia. Antigens being bound to the solid phase by the human anti-PUU and anti-DOB/HTN IgM antibodies were detected by a broadly reacting polyclonal rabbit anti PUU-recombinant nucleocapsid protein antiserum. The IgM isotype was proven to be at least five times more efficient than IgG when used as the capturing antibody. The sensitivity of the PUU antigen ELISA was approximately 0.5 ng/ml, as measured by titration with a PUU recombinant nucleoprotein antigen. Cell-associated PUU antigen in tissue culture was seen after 48 hr by the PUU-ELISA and after 96 hr by
Japanese encephalitis (JE) virus is a major cause of neurologic infection in Asia, but surveillance has been limited. Three JE immunoglobulin M (IgM) antibody capture enzyme-linked immunosorbent assay kits have recently been developed. The aim of this study was to evaluate their sensitivity, specificity, and usability using 360 acute-phase serum samples containing JE, dengue, or neither IgM antibody. The kits, manufactured by Panbio Limited, Inbios International, Inc., and XCyton Diagnostics Ltd, had high sensitivities of 89.3%, 99.2%, and 96.7%, respectively. The specificities were 99.2%, 56.1%, and 65.3%, respectively. When dengue IgM-positive samples were excluded, the kits had specificities of 98.4%, 96.1%, and 96.1%, respectively. The Panbio kit includes both JE and dengue antigens and appears to have an advantage in settings where dengue virus co-circulates, although further assessments in clinical settings are needed. This information is helpful in considering options for strengthening the
We have identified a set of natural IgM antibodies in human serum that are reactive with protamines, a class of low molecular weight basic nucleoproteins that are synthesized de novo in the postpubertal testis and are unique to sperm. Those antibodies were detected by ELISA in significant titer in all of 100 sera of normal adult males and females and in 26 of 28 sera of normal pediatrics aged 7 d to 2 yr. Commonality between the protamine-reactive IgM antibodies of pediatric and adult sera was established by the demonstration of similarity in antigen recognition and reaction kinetics. Therefore, the role of protamines as either immunogenic stimulus or antigenic target of that set of natural antibodies is not likely. The antigenic site recognized by the protein-reactive serum IgM antibodies was characterized by comparison with the pattern of antigen recognition by a monoclonal antibody to human sperm protamines (HPmAb). By the use of synthetic peptides simulating the amino acid sequences of ...

Delayed and variable antibody responses to HCV make it difficult to diagnose acute HCV infection reliably. Immunoglobulin (Ig)M and IgG anti-HCV may be observed simultaneously as disease persists. IgM plays a key role in mixed cryoglobulinemia (MC), an immune complex disease strongly associated with persistent HCV infection. In MC, clonal or oligoclonal IgM rheumatoid factors facilitate the deposition of immune complexes in small blood vessels and tissue, leading to inflammation, complement activation and tissue damage. Clonally expanded IgM(+)κ(+) B-cells expressing rheumatoid factor-like IgM are abundant in many HCV patients with MC. The observation that identical or similar IgM antibodies are expressed in different patients clonally expanded B-cells supports the hypothesis that MC is driven by antigen-specific B-cell activation, rather than polyclonal B-cell activation or HCV replication in B-cells. More study is required to identify the antigens that drive the development of MC.

Guidance for the deployment of the Emergency Use Approval (EUA) Zika virus testsOn March 25, CMS provided guidance regarding the deployment of the EUA Zika virus tests, approved by CLIA, to state and local Public Health Laboratories (PHL) by the CDC. Two Zika virus tests with corresponding protocols have been developed by the CDC for use by state PHLs and have received EUA by the FDA. If test kits are noted during surveys, Regional Offices (RO) must confirm that the Zika Immunoglobulin M Antibody Capture Enzyme-Linked Immunosorbent Assay and/or the Trioplex Real Time RT-PCR Assay was verified by each laboratory per the CDC protocol, and that corresponding CLIA policies and procedures are in place to ensure readiness and compliance in the event of an outbreak. Upon receipt of the Zika virus test system and corresponding instructions and information, state PHLs will verify the developed test specifications in their laboratory per the CDCs guidance.
Summary In July 2016, CDC issued Interim Guidance for Health Care Providers Caring for Pregnant Women with Possible Zika Virus Exposure - United States, July 2016 (https://www.cdc.gov/mmwr/volumes/65/wr/mm6529e1.htm) that includes Zika virus immunoglobulin M (IgM) testing of pregnant women. However, some flavivirus infections can result in prolonged IgM responses (,12 weeks) that make it difficult to determine the timing of infection, especially in testing of asymptomatic people. Emerging epidemiologic and laboratory data indicate that Zika virus IgM can persist beyond 12 weeks in a subset of infected people. Therefore, detection of IgM may not always indicate a recent infection. Although IgM persistence could affect IgM test interpretation for all infected people, it would have the greatest effect on clinical management of pregnant women with a history of living in or traveling to areas with Zika virus transmission. Pregnant women who test positive for IgM antibody may have been infected with ...
Immunoglobulin M (IgM) is the largest circulating antibody molecule in humans. It consists of a heavy chain (?-chain) and a light chain (κ- or λ-chain), as well as 5 base units and 10 binding sites, though it cannot bind all 10 simultaneously because of steric hindrance. IgM chain C refers to the constant region of the IgM heavy chain that is involved in immune regulation. IgM forms polymers by covalently linking multiple immunoglobulins together with disulfide bonds. It normally exists as a pentamer, but occasionally as a hexamer. Because of its polymeric nature, IgM has high avidity, and it is especially effective at complement activation. Due to its large size, IgM does not diffuse well, and it is found in the interstitium in very low amounts. IgM is mainly found in serum; however, because of the J chain, it is also important as a secretory immunoglobulin. IgM is the first immunoglobulin expressed by mature B cells, and it normally appears early in the course of an infection and does not ...

Effect of anti-γ chain and anti-µ chain on secondary antibody response of rabbit spleen cells was studied in vitro. Spleen cells from rabbits primed with dinitrophenylbovine γ globulin (DNP-BGG) were stimulated in vitro with the antigen either in the presence or absence of anti-heavy chain antibody. After 24 hr of incubation, the cells were washed and cultured in the absence of the antigen. Antibody response was evaluated by enumerating IgG and IgM antibody producing cells and by measuring anti-DNP antibodies in culture media. It was found that anti-γ chain suppressed both IgG and IgM antibody response, while anti-µ chain suppressed only IgM antibody response. When the primed cells were cultured without antigen stimulation, IgM antibody producing cells increased after 3 days culture.

Introduction: It is hypothesized that IgM antibodies to oxidized LDL are anti-atherogenic. Myeloperoxidase from plaque-infiltrating neutrophils catalyzes the production of hypochlorite (HOCl), which oxidizes LDL. Here we study the IgM response to HOCl-modified LDL in comparison to titers of T15 clonotypic natural antibodies. Methods: Plasma of LDLR-/- mice fed a normal chow or high-fat diet was obtained after 6 and 16 weeks. The IgM responses to HOCl-modified LDL and T15 clonotypic natural IgM antibodies were measured by ELISA. Results: The IgM levels in response to HOCl-modified LDL increased dramatically in the atherosclerotic group after introduction of the high-fat diet, but not in mice on normal chow. The natural IgM T15 clonotypic antibody titers revealed a more moderate increase during atherogenesis. Conclusion: Our results show that during atherogenesis there is a strong induction of IgM antibodies to HOCl-modified LDL particles. Whether these induced IgM antibodies are pro- or ...
Major depression and chronic fatigue syndrome (CFS) are accompanied by signs of oxidative and nitrosative stress (O&NS) and an inflammatory response. Phosphatidyl inositol (Pi) is thought to play a role in depression. The aim of the present study is to examine whether depression and CFS are characterized by an IgM-mediated immune response directed against Pi. Toward this end, this study examines the serum IgM antibodies directed against Pi in 14 patients with major depression, 14 patients with CFS, 14 subjects with partial CFS, and in 11 normal controls. We found that the prevalence and mean value for the serum IgM levels directed against Pi were significantly greater in patients with major depression and CFS than in normal controls and patients with partial CFS. There were significant and positive correlations between serum IgM levels directed against Pi and two symptoms of the FibroFatigue Scale, i.e. fatigue and depression. The results show that an IgM-related immune response directed against ...
Waldenstroms Macroglobulinemia Symptom: A few patients dont have side effects. For the individuals who have side effects, the most well-known ones are shortcoming, serious weakness, seeping from the nose or gums, weight reduction, and wounds or other skin sores. Seriously large amounts of IgM can prompt hyperviscosity disorder, in which the blood turns out to be unusually thick. Waldenstroms Macroglobulinemia Symptoms of this disorder incorporate visual issues (e.g., obscuring or loss of vision) and neurological issues (e.g., migraine, discombobulation, vertigo). Amid a physical exam, a specialist might likewise discover swelling of the lymph hubs, spleen, and/or liver.. Waldenstroms Macroglobulinemia Causes:. Waldenstroms macroglobulinemia is a consequence of a condition called lymphoplasmacytic lymphoma. The reason for the overproduction of the IgM counter acting agent is obscure, yet specialists trust it is made by lymphoma cells. Overproduction of Waldenstroms Macroglobulinemia Causes ...
A solid-phase immune electron microscopy method that uses protein A, goat anti-human immunoglobulin M (IgM), and human serum is described. Evaluation of the method with different immunoglobulin fractions showed that human IgM constituted the major virus capture antibody. The method appeared to distinguish between two Norwalk-like virus serotypes and demonstrated specific IgM responses to these serotypes in infected individuals. Further work is being carried out to define the relationship of these two serotypes to the previously described Norwalk agent (A. Z. Kapikian, R. G. Wyatt, R. Dolin, T. S. Thornhill, A. R. Kalica, and R. M. Chanock, J. Virol. 10:1075-1081, 1972), and four subsequent hospital outbreaks are being studied. ...

We have investigated the importance of glycosylation in determining the function of membrane-bound and secreted immunoglobulin M (IgM). Hickman and Kornfeld (1978) previously observed that glycosylation is required for IgM to be secreted by 104E, a mouse plasma cell tumor. In order to determine whether this requirement is a general one for all forms of IgM, we have used WEHI 279.1, a mouse B lymphoma that synthesizes both the membrane and secreted forms of IgM. In the presence of 5 microgram/ml tunicamycin (Tm), glycosylation of both membrane and secreted IgM is at least 90% inhibited, but total protein synthesis is equivalent in control and Tm-treated cells. Despite the absence of carbohydrate, IgM molecules are properly assembled into monomers for membrane localization. Cells whose surfaces have been stripped of membrane IgM by treatment with anti-mu antibody resynthesize the IgM equally well in the presence or absence of Tm. It is more surprising that the assembly of IgM into pentamers and the

Streptococcus pneumoniae is the most common cause of pneumonia, which claims the lives of people over the age of 65 seven times more frequently than those aged 5-49. B-1a cells provide immediate and essential protection from S. pneumoniae through production of natural immunoglobulin, which is germline-like due to minimal insertion of N-region additions. We have previously demonstrated B-1a derived phosphorylcholine (PC)- specific and total IgM moves away from the germline with age as a result of selection. Consequently, the protective capacity of natural serum IgM against S. pneumoniae infection is significantly decreased in aged mice. Anti-phosphatidylcholine (PtC) antibodies, like anti-PC antibodies, contain few N-additions, and have been shown to be essential in protection from bacterial sepsis. Herein, we demonstrate the number of N-additions in PtC-specific B-1a cell antibodies do not change with age. Furthermore, the average percent of B-1a cells binding PtC-liposomes (13-15%) did not ...

Despite improvements in antimicrobial therapy and supportive care, sepsis is still a major public health issue. Recently, CD100 and its receptor in the immune system CD72 were shown to play a major role in immune regulation. The purpose of this study was to investigate the expression and clinical correlations of CD72 and CD100 on circulating lymphocytes of septic patients. In total, 24 healthy controls and 54 septic patients were enrolled in this study. Considering the focus of the current study was on the immunosuppressive phase of sepsis, blood samples of patients were collected at days 3-4 after the onset of sepsis. The levels of CD72 and CD100 expression on circulating lymphocytes were measured by flow cytometry and serum IL-6, IL-10, and immunoglobulin M levels were determined by enzyme-linked immunosorbent assay. Our results showed that the levels of CD100 expression on T cells and CD72 expression on B cells were significantly lower in septic patients. Similarly, a significant decrease in the
The diagnosis of parasitic infections is definitively made by the identification of parasites in host tissue or excreta. The detection of antibodies can be very useful as an indicator that an individual has been infected with a specific parasite. A positive result for a person with no exposure to the parasite prior to recent travel in an area where disease is endemic may be interpreted as indicating recent infection. In general, the detection of antibodies to parasitic diseases indicates only infection at some indeterminate time and not necessarily an acute or current infection. The detection of specific immunoglobulin M (IgM) and IgA antibodies may be of value in determining the approximate time of initial infection with Toxoplasma gondii, but it is not recommended for any other parasitic disease. The diagnosis of human intestinal protozoa depends on microscopic detection of the various parasite stages in feces, duodenal fluid, or small intestine biopsy specimens.

Normal saline (NSS, NS or N/S) is the commonly used phrase for a solution of 0.90% w/v of NaCl, 308 mOsm/L or 9.0 g per litre. Less commonly, this solution is referred to as physiological saline or isotonic saline (because it closely approximates isotonic, that is, physiologically normal, solution); although neither of those names is technically accurate (because normal saline is not exactly like blood serum), they convey the practical effect usually seen: good fluid balance with minimal hypotonicity or hypertonicity. NS is used frequently in intravenous drips (IVs) for people who cannot take fluids orally and have developed or are in danger of developing dehydration or hypovolemia. NS is also used for aseptic purpose. NS is typically the first fluid used when hypovolemia is severe enough to threaten the adequacy of blood circulation, and has long been believed to be the safest fluid to give quickly in large volumes. However, it is now known that rapid infusion of NS can cause metabolic ...
PICCs can remain in situ for extended periods of time, from seven days to 4 months [4] up to 12 months although little information is available with respect to viability timeframes. They are used in both the hospital and community settings. PICCs can be used for intravenous delivery of total parenteral nutrition (TPN), chemotherapy, antibiotics or other medications, and can also be used for blood sampling if the lumen is 4 French or larger in size (Arrow and Bard manufacturers guidelines). To maintain patency, PICC management should include regular flushing with normal saline and "locking" with Heparin or normal saline when not in use. The type of locking procedure depends on the type of PICC and bung; Groshong PICCs have a three-way valve at the tip so the use of a heparin lock is not necessary, and there are no clamps on the external length. In comparison, Arrow PICCs have clamps on the exterior line and require a heparin lock. The use of heparin to maintain line patency, though, is ...
Ringer's lactate has an osmolarity of 273 mOsm L−1.[12] The lactate is metabolized into bicarbonate by the liver, which can help correct metabolic acidosis. Ringer's lactate solution alkalinizes via its consumption in the citric acid cycle, the generation of a molecule of carbon dioxide which is then excreted by the lungs. They increase the strong ion difference in solution, leading to proton consumption and an overall alkalinizing effect.[13] The solution is formulated to have concentrations of potassium and calcium that are similar to the ionized concentrations found in normal blood plasma. To maintain electrical neutrality, the solution has a lower level of sodium than that found in blood plasma or normal saline.[4] Generally, the source of the constituent ions is a mixture of sodium chloride (NaCl), sodium lactate (CH3CH(OH)CO2Na), calcium chloride (CaCl2), and potassium chloride (KCl), dissolved into distilled water. Ringer's solution has the same constituents without the sodium lactate, ...

... (RL), also known as sodium lactate solution and Hartmann's solution, is a mixture of sodium chloride, sodium lactate, potassium chloride, and calcium chloride in water.[1] It is used for replacing fluids and electrolytes in those who have low blood volume or low blood pressure.[2] It may also be used to treat metabolic acidosis in cases other than those caused by lactic acidosis and to wash the eye following a chemical burn.[2][3] It is given by injection into a vein or applied to the affected area.[2][3]. Side effects may include allergic reactions, high blood potassium, volume overload, and high blood calcium.[2] It may not be suitable for mixing with certain medications and some recommend against use in the same infusion as a blood transfusion.[4] Ringer's lactate solution has a lower rate of acidosis as compared with normal saline.[1][4] Use is generally safe in pregnancy and breastfeeding.[2] Ringer's lactate solution is in the crystalloid family of medication.[5] ...

Only a limited number of emulsifiers are commonly regarded as safe to use for parenteral administration, of which the most important is lecithin.[medical citation needed] Lecithin can be biodegraded and metabolized, since it is an integral part of biological membranes, making it virtually non-toxic. Other emulsifiers can only be excreted via the kidneys,[citation needed] creating a toxic load. The emulsifier of choice for most fat emulsions used for parenteral nutrition is a highly purified egg lecithin,[36] due to its low toxicity and complete integration with cell membranes. Use of egg-derived emulsifiers is not recommended for people with an egg allergy due to the risk of reaction. In situations where there is no suitable emulsifying agent for a person at risk of developing essential fatty acid deficiency, cooking oils may be spread upon large portions of available skin for supplementation by transdermal absorption. Another type of fat emulsion Omegaven is being used experimentally within the ...
