Methotrexate
A Folate folic acid ; is initially reduced to dihydrofolate by dihydropteroate synthetase. B Dihydrofolate if further reduced to tetrahydrofolate by dihydrofolate reductase. C Metthotrexate inhibits this pathway through competitive inhibition of dihydrofolate reductase DHFR ; . D Dapsone and various sulfonamides inhibit dihydropteroate synthetase, and thus, can amplify the inhibition of DHFR by methotrexate. E Trimethoprim including fixed combinations with sulfamethoxazole ; also inhibits DHFR, and thus can amplify the inhibition of this pathway by methotrexate. F Folic acid given in therapeutic doses essentially competes with methotrexate for DHFR, reducing the adverse effects of methotrexate by tetrahydrofolate production. G Folinic acid, in a sense does an "end run" around the methotrexate inhibition of folate, serving as a fully reduced substrate for pyrimidine synthesis.

Substrate 50 mg DAB, 40 mg ammonium chloride, 200 mg -D-glucose, and 3 mg glucose oxidase in 100 ml of 0.1 M phosphate buffer ; was added to the slices that were then incubated in the dark at 37C for 1 to 2 until a dark brown black color was noted. Slices were mounted on glass slides and a coverslip was positioned with 90% glycerol. Slides were dried for 10 min prior to observation under a light microscope. Two investigators, who were unaware of the experimental conditions, counted the number of capillaries leaking HRP in four sections of the hippocampus and striatum 10 magnification ; from each rat. Leaks were recognized by the presence of HRP immediately outside of the capillary wall Fig. 1 ; . A mean of the percentage increase SEM was computed by dividing the number of leaks in treated rats by the number in controls, multiplied by 100. Immunocytochemistry for albumin extravasation. Rats were treated with paraoxon, anesthetized with xylaket, and perfused after 10 min with fixative 4% paraformaldehyde in 0.15 M phosphate buffer, pH 7.2 ; through the heart. Brains were excised and placed in fixative for 72 h and incubated 2 days at 4C in 30% sucrose in PBS. Sections were cut to 25 m with a cryostat and dried. Next, sections were incubated with 10 mM sodium citrate buffer, pH 6.0, and.
Based on the disease activity score in 28 joints das28 ; , 50% of patients treated with combined therapy achieved clinical remission at 52 weeks compared with 28% of those given methotrexate alone p 0001.
3. The prescribed dose for methotrexate in non-malignant conditions is usually once a week and must specify the day of the week on which the dose is to be taken. Monday should be avoided. 4. Prescribers and other health care practitioners as appropriate must carefully advise the patient of the dose and frequency of oral methotrexate and of the number of tablets or quantity of liquid they require to make up their dose. NB 2.5mg is the only strength of tablet used and 10mg 5ml is the only strength of liquid used. 5. For in-patients when weekly oral methotrexate is prescribed and where the Kardex style allows, the prescriber must cross out the six days of the week in the administration section of the Kardex when a dose must not be administered. The day of the week on which the dose is to be taken must also be specified in the special instructions additional information section of the Kardex. 6. Discharge and outpatient prescriptions and discharge summary information must state the dose, frequency, formulation and day the oral methotrexate is to be taken. `As directed' must not be used as a dosage instruction. 7. Full medication reviews, conducted where possible by pharmacists, must be undertaken on admission and discharge and at review clinic appointments. 8. All prescribing, monitoring and administration requirements should be recorded in the patient's notes. 9. Information on medicines interacting with methotrexate is available from the BNF, SPC and Medicines information. In particular, concomitant trimethoprim or cotrimoxazole must not be prescribed due to the risk of pancytopenia. 10. When discharging patients newly initiated on methotrexate, prescribers should follow the agreed regional Shared Care Guideline. Monitoring oral methotrexate 1. Patients receiving oral methotrexate should be monitored to identify possible signs of toxicity. Be aware of patients who attend with symptoms such as breathlessness, dry persistent cough, vomiting or diarrhoea as these may be signs of oral methotrexate toxicity or intolerance. 2. The patient's current monitoring schedule on admission should be confirmed and existing test results checked as appropriate. 3. For inpatients, the monitoring schedule for the admission should be agreed taking account of the pre-admission monitoring schedule and current clinical condition. For outpatients, the regional Shared Care Guideline for oral methotrexate should be referred to for information on monitoring.3 Electronic prescribing and dispensing systems 1. Electronic prescribing and dispensing systems must only offer methotrexate 2.5mg tablets or 10mg 5ml liquid as available strengths. 2. If an incorrect dose, strength or frequency has been entered into an electronic system, it should be removed. The correct information must be added and an annotation made that an incorrect entry had been made.

K. T. Yein, D. Rees and R. Williams Rheumatology, The County Hospital, Hereford, Herefordshire, UK Background: Leflunomide is widely used a new disease modifying agent DMARD ; . It has anti-inflammatory, anti-proliferative and immunomodulatory actions and as effective as Methotrexste in controlling rheumatic diseases. However there are limited data on serious ; adverse effects. We present a case of fatal pulmonary complication related to Leflunomide. Methods: A 68-yr-old lady with 17-yr history of sero-negative rheumatoid arthritis RA ; presented to acute admission unit with worsening dyspnoea over a few months with exercise tolerance of six steps. Past medical history included mild asthma, diagnosed in 2002, pulmonary abscess in right middle lobe October 2003 ; with persistent, single15 mm thinwalled cavity with no other significant changes on CT chest December 2003 ; and on CXR December 2005 ; . She had been on Leflunomide 20 mg daily for 26 months before this admission, Prednisolone 5 mg and Diclofenac. Previous DMARD's were MTX 19932003 ; , Sulphasalazine, Gold and Penicillamine. She was non-smoker, did not keep pets or birds, and had no past history of TB contact ; , or travel to risky areas. Clinical examination was consistent with severe chest infection. Blood tests showed WBC 10.5 neutrophil 9.5 and lymphocytes 0.2 CRP 240 and the rest were satisfactory. CXR showed multiple large cavitating ring shadows in both lung fields. Mycobacterium avian intracellulare MAI ; was isolated from bronchioalveolar lavage. She had several complications with pneumothorax, MRSA, and aspergillous infection. Despite aggressive appropriate treatment with antibiotics and invasive ventilatory support, she died 29 days later.

1240 individuals with rheumatoid arthritis met our inclusion criteria. The mean length of follow-up until death or censoring was 6 years SD 5; 91 007 total personmonths ; . By the end of follow-up, 588 patients had received methotrexate mean dose 13 mg per week.
Over longer treatment durations 24 months ; , leflunomide appeared to be at least as effective as methotrexate and more effective than sulfasalazine and trileptal.
Recently, to provide therapeutic drug monitoring effectively and more practically, limited sampling methods to estimate methotrexate pharmacokinetics using a Bayesian approach and population data modelling programs have been implemented.[50-52] 2. Pharmacodynamics Methotexate is an analogue of folic acid that was originally designed to inhibit the activity of the enzyme DHFR. This enzyme converts dihydrofolates to tetrahydrofolates, which are involved in single carbon atom transfers in crucial intracellular metabolic pathways such as de novo synthesis of purines, pyrimidines and polyamines and transmethylation of phospholipids and proteins. In oncology, the rationale for the use of HDMTX is that malignant cells become starved of the purine and pyrimidine precursors required for DNA and RNA synthesis, proliferation and cell division. As a result of their inability to synthesise DNA and RNA, the number of malignant cells rapidly falls under such therapeutic conditions.[53] LDMTX has immunosuppressive and antiinflammatory properties.

Fuse primers are trimmed lengths of safety fuse to which a fuse blasting cap has been attached. The operation of making fuse primers is simply cutting and capping fuse lengths.which is relatively simple. However, this is one of the most important jobs in blasting, because it must be done with great care and attention to detail. Errors or sloppiness can have serious results! First, examine the piece of fuse. If the protective coatings appear to have been damaged.discard it. If it appears to have deteriorated.discard it. Fuse is cheap and misfires are costly and dangerous. Then cut at least one inch from both ends of the length of fuse you have selected. The black powder core rapidly absorbs moisture through the fuse-ends and we minimize the chances of this causing us trouble by trimming off the ends. Care must be taken in cutting safety fuse. Preferably it should be cut with the cutting portion of the capcrimper tool. If you are using a knife it should be clean, dry and very sharp. The fuse should be placed across a flat surface so it is time sharply bent, and the cuts should be Slanting cuts prevent proper seating of the fuse in the cap. If a cut is not square, don't settle for it.cut it again. Under no circumstances should you cut fuse with shears or wire cutters. This will often squeeze the fuse out-of-round.distorting the power train and making for difficult insertion of the fuse into the cap. After you have made the cut, examine the cut end closely. Sometimes the waterproofing compounds in the fuse become sheared over the powder core pecially if the fuse is very warm or the knife is dull or dirty. This will prevent proper ignition. Sometimes, fuse is flattened or This makes it difficult to insert happens, simply roll the ends of the palms of your hands a few proper shape. crushed out-of-round when cut. into the cap. When this the fuse back and forth between times and it should return to its.

Cancer Research Animals. Male athymic nude mice NCI-nu ; were purchased from the Animal Production Area of the National Cancer Institute-Frederick Cancer Research Facility Frederick, MD ; . The mice were housed and maintained in specific pathogen-free conditions in facilities approved by the American Association for Accreditation of Laboratory Animal Care that met all current regulations and standards of the U.S. Department of Agriculture, U.S. Department of Health and Human Services, and NIH. The mice were used in accordance with institutional guidelines when they were 6 to 8 weeks old. Therapeutic agents. Zoledronate was dissolved in 5% glucose in water ; . STI571, a novel PDGFR tyrosine kinase inhibitor Novartis Pharmaceuticals ; , was dissolved in distilled water. Paclitaxel Taxol ; purchased from BristolMyers Squibb Princeton, NJ ; was diluted in distilled water for i.p. injection. In vitro effects of zoledronate on PC-3MM2 cells. PC-3MM2 cells 1.2 103 ; were seeded into each well of 96-well plates and allowed to adhere overnight. The medium was removed and replaced with either medium with 0.1% FBS or medium with 0.1% FBS containing 1, 2.5, 5, and 1, 000 nmol L zoledronate. Medium with 0.1% FBS containing 1, 2.5, 5, and 1, 000 nmol L paclitaxel was used to compare cytotoxicity. After 96 hours of incubation, the number of metabolically active cells per well triplicate wells per group ; was determined by the 3- 4, 5-dimethylthiazol-2-yl ; -2, 5-diphenyltetrazolium bromide MTT ; assay. Stock solution of MTT M2128; Sigma Chemical Co., St. Louis, MO ; was prepared by dissolving 5 mg MTT in 1 ml PBS and filtering the solution to remove particulates. The solution was protected from light and stored at 4jC. Following a 2-hour incubation period in medium containing 0.42 mg ml MTT, the PC-3MM2 cells were lysed in DMSO. The conversion of MTT to formazan by metabolically active cells was monitored by Ceres UV900C, a 96-well micrometer plate reader at 570 nm Bio-Tek Instruments, Inc., Winooski, VT ; . Growth inhibition was calculated by the formula: cytostasis % ; [1 A B ; 100, where A is the total number of cells and B is the number of cells in the test group. IC50 was obtained from the plotted curves. Intratibial injection of tumor cells. To produce tumors in the tibia, PC3MM2 cells were harvested from subconfluent cultures by a 2-minute exposure to 0.25% trypsin and 0.02% EDTA. Then, medium containing 10% FBS was added and the cells were washed once in serum-free medium and resuspended in Ca2 + - and mg2 + -free HBSS. Cell viability was determined by trypan blue exclusion, and only single-cell suspensions of 95% viability were used for injection. Male nude mice were anesthetized with Nembutal Abbott Laboratories, North Chicago, IL ; , and tumor cells were injected intraosseously into the tibia as described previously 31, 35 ; . The animals tolerated this procedure well, and no anesthesia-related deaths occurred. Therapy of human prostate cancer cells growing in the tibias of athymic nude mice. Zoledronate dissolved in water containing 5% glucose was injected s.c. twice daily. STI571 dissolved in distilled water at 6.25 mg ml was given orally once daily. Paclitaxel diluted in water was injected i.p. once weekly. In the first set of experiments, we determined the optimal dose and schedule of zoledronate necessary to prevent osteolysis. Three days after the implantation of PC-3MM2 cells into the tibia, five mice were killed and the presence of actively growing cancer cells in the bone cortex was ascertained by histologic examination as described previously 39, 43 ; . Injected mice were randomized into six treatment groups n 10 ; : control mice receiving twice daily s.c. injections of 5% glucose in water and once weekly i.p. injections of distilled water; b ; mice receiving once weekly i.p. injections of paclitaxel 8 mg kg ; and twice daily s.c. injections of 5% glucose in water; c ; mice receiving twice daily s.c. injections of zoledronate 125 Ag kg ; and once weekly i.p. injections of distilled water; d ; mice receiving twice daily s.c. injections of zoledronate 25 Ag kg ; and once weekly i.p. injections of distilled water; e ; mice receiving twice daily s.c. injections of zoledronate 5 Ag kg ; and once weekly i.p. injections of distilled water; and f ; mice receiving twice daily s.c. injections of zoledronate 1 Ag kg ; and once weekly i.p. injections of distilled water. All of the mice were treated for 5 weeks when tumor size, lymph node metastasis, and osteolysis of the injected bone were evaluated. This experiment was done twice. In the next set of experiments, we determined the therapeutic effects of combining zoledronate, STI571, and paclitaxel against PC-3MM2 tumors into the tibia of nude mice and preservation of the bone. To do so, mice were injected with PC-3MM2 in the tibia and 3 days later were randomized into eight groups n 10 ; as follows: a ; daily oral administrations of distilled water, twice daily s.c. injections of 5% glucose in water, and once weekly i.p. injections of distilled water; b ; once weekly i.p. injections of paclitaxel 8 mg kg ; , daily oral administrations of distilled water, and twice daily s.c. injections of 5% glucose in water; c ; daily oral administrations of STI571 50 mg kg, biological optimal dose as determined previously; ref. 31 ; , twice daily s.c. injections of 5% glucose in water, and once weekly i.p. injections of distilled water; d ; twice daily s.c. injections of zoledronate 25 Ag kg, optimal biological dose determined from the first set of experiments ; , twice daily oral administrations of distilled water, and once weekly i.p. injections of distilled water; e ; daily oral administrations of STI571 50 mg kg ; , once weekly i.p. injections of paclitaxel 8 mg kg ; , and twice daily s.c. injections of 5% glucose in water; f ; twice daily s.c. injections of zoledronate 25 Ag kg ; , once weekly i.p. injections of paclitaxel 8 mg kg ; , and daily oral administrations of distilled water; g ; daily oral administrations of STI571 50 mg kg ; , twice daily s.c. injections of zoledronate 25 Ag kg ; , and once weekly i.p. injections of distilled water; and h ; daily oral administrations of STI571 50 mg kg ; , twice daily s.c. injections of zoledronate 25 Ag kg ; , and once weekly i.p. injections of paclitaxel 8 mg kg ; . All of the mice were treated for 5 weeks when tumor size and osteolysis were evaluated by gross observation, necropsy, and digital radiography. Incidence of bone tumors and lymph node metastasis were confirmed by histologic examination and H&E staining. Immunohistochemical analyses for various markers and tartrate-resistant acid phosphatase TRAP ; staining for functioning osteoclasts were done as described below. This experiment was repeated twice. Digital radiography and harvest of tumors. After 3 or 4 weeks of treatment, mice were anesthetized with Nembutal 0.5 mg g body weight ; and placed in a prone position. Digital radiography of the hind legs was carried out using the Faxitron MX-20 X-ray machine Faxitron X-ray Corp., Wheeling, IL ; . On week 6 of the study, the mice were euthanized by injection with Nembutal and weighed. Digital radiography of the hind limbs of each mouse was carried out and incidence of bone tumors was recorded. The legs with tumor and the uninjected contralateral legs were resected at the head of the femur and weighed. Net tumor weight was calculated by subtracting the weight of the control leg from that of the leg with tumor. The legs with tumors were prepared for histologic studies as described below. Mice were autopsied and all enlarged lymph nodes were resected and fixed in formalin. The presence of tumor cells in the bones and lymph nodes was confirmed by histology following H&E staining.

Ectopic pregnancy methotrexate effects
Aminopterin is a folic acid inhibitor found in some rodenticides available outside the USA. It is not available in the US as a rodenticide. Aminopterin is a 4-amino analog of folic acid. It was originally used as an antineoplastic agent in the late 1940's but has been superseded by methotrexate, a related but less toxic folic acid analog. At high doses, methotrexate results in acute renal failure and crystalluria due to deposition of 7-hydroxymethotrexate in the renal tubules. Aminopterin toxicity is thought to be similar and dose dependent and pletal.

Does methotrexate work to treat rheumatoid arthritis.
Based on western studies, asthma accounts for approximately 134, 000 hospital admissions per annum, the average stay being 8.3 days. In this study, the average hospital stay is less than 7 days. Among those who were admitted, only ] 10% ; had to stay for more than 2 weeks because she had to be intubated for the severity of her asthmatic attack. Families with asthmatic members may spend as much as 18% of their total income on treatment. How can the 62.9% of our patients who are jobless cope up with this problem?
