The determination of drug-related impurities is currently the principal role of CE within pharmaceutical analysis and presents a challenge to both selectivity and sensitivity. The main component and structurally related impurities have similar chemical properties and thus make resolution difficult. However, an advantage of CE over its chromatographic counterparts is that high separation efficiencies are achievable. The resulting peak sharpness often translates a small degree of selectivity to acceptable resolution. A detection limit of 0.1% area area is widely accepted as a minimum requirement for a related impurities determination method. This 0.1% level is possible by CE. For example, Figure 1 Swartz, 1991 ; shows determination of salicylamide-related impurities at 0.1% area area and below. HPLC can routinely decrease this level by up to order of magnitude 0.01% ; . Owing to the possibility that a formulation or 2. 24. Kader HA, Wenner W, Telega GW, Maller ES, Baldassano RN.

Absence of any accounting adjustments, we expect the Company to record full-year revenue of $15.4 million and a net profit of $2.63 million, representing a year-on-year increase of 27.2% and 217.5% respectively. For the first nine months of FY2006 and the full year FY2005, gross margins for TCM were approximately 35%40%, while those for veterinary medicines were approximately 30%33%. Gross margin for stevioside was below 30% due to high raw-material costs. However, overall gross margins have been relatively stable at 28%32%, even on a quarterly basis. We believe the Company will maintain gross margins in excess of 30% in FY2007 and FY2008, as management has taken steps to ensure a stable supply of raw materials by increasing the prepayment to raw-material suppliers. Looking ahead, we continue to expect robust growth in both revenue and net profit in FY2007 and FY2008. Our optimism is mainly due to the fact that Sunwin is operating in a large and growing neutraceuticals industry, where demand for health food and TCM-based medicines is growing. The Company's aggressive capital expenditure in excess of $4 million this year to upgrade and expand its production facilities, R&D and aggressive marketing plan to penetrate the North American natural-sweetener and health-food markets is expected to bear fruit. Due to the continuing introduction of new veterinary medicine and TCM products, increasing awareness of the need to control animal disease, such as avian flu, and GMP requirements which we believe should help Sunwin to capture market shares from the smaller players, we project the combined revenue of Chinese and animal medicine to grow 49% in FY2007 and 33.5% in FY2008. The latest news that Sunwin has received purchase orders for 125 tons of stevioside in the first three months of this year, or 500 tons on an annualized basis, leads us to believe that our assumption of 405 tons in sales of self-produced stevioside and 100 tons from resale is achievable. At an average selling price of $33, 000 per ton compared to the current price of $35, 000 per ton, we are confident of our projected revenue of $16.66 million for stevioside in FY2007. In FY2008, we believe the marketing plan to penetrate the North American market this year should help bolster sales of stevioside by 35.4% to 684 tons. Assuming margins show slight improvement due to greater economies of scale and the product price remains steady at $34, 000 per ton, we project revenue of $23.3 million. The projected $2.5 million of sales of stevioside in small packs represents less than 4% of total volume sales. Whether this can be realized or not should not significantly affect the overall bottom line in FY2008. LEENDERT H. OTERDOOM, BSC AIKO P.J. DE VRIES, MD WILLEM J. VAN SON, MD, PHD JAAP J. HOMAN VAN DER HEIDE, MD, PHD RUTGER J. PLOEG, MD, PHD RON T. GANSEVOORT, MD, PHD PAUL E. DE JONG, MD, PHD RIJK O.B. GANS, MD, PHD STEPHAN J.L. BAKKER, MD, PHD not yet been validated in comparison to the hyperinsulinemic-euglycemic clamp in the stable renal transplant population. Indexes that are based on fasting blood parameters alone have distinct advantages over other methods of quantifying insulin resistance in that they are less cumbersome and less time consuming for large-scale epidemiological studies at outpatient clinics. However, established indexes have been derived from correlates of insulin resistance in nontransplant populations. Evidence suggests that insulin resistance in the renal transplant population may be caused by other risk factors as well, such as immunosuppression and antihypertensive medication 6 ; . Consequently, it remains uncertain whether these indexes are applicable to the stable renal transplantation population. The primary objective of this study was, therefore, to validate established insulin resistance indexes based on fasting blood parameters in a stable renal transplant population. The second objective was to investigate which risk factors, both traditional and those specifically related to the transplant population, are associated with insulin resistance. RESEARCH DESIGN AND METHODS -- The institutional review board approved the study protocol METc 01 039 ; , which was in adherence with the Declaration of Helsinki 7 ; . Patients from the renal transplant outpatient population, who were part of a previous study cohort 3 ; , were randomly invited to participate. Recruitment was performed in a stratified manner so that similar numbers of male and female subjects and similar numbers of participants with a high and a low waist-to-hip ratio would be included. Subjects were eligible for participation in the present study if they had received a renal allograft at our center at least 2 years before the start of the study and used cyclosporine microemulsion Neoral; in combination with prednisolone and or azathioprine, mycophenolate mofetil, or rapamycin ; as part of their immunosuppressive regimen. Inclusion required a stable allograft function, defined as a 24-h urinary creatinine clearance of 30 ml min and a difference in 24-h urinary creatinine clearance over the and bentyl. Ileoanal pouches: complications Portal vein thrombi Remzi and cols reviewed the incidence of portal vein thrombi PVT ; in patients who underwent restorative proctocolectomy RP ; at Cleveland Clinic. Ninety-four from a total of 702 patients had a CT scan within the postoperative period. PVT was diagnosed in 42 of these patients 45% ; . The indications for CT scan included abdominal pain, fever, leukocytosis, and delayed bowel function. Septic complications of RP caused these symptoms and signs in 45 patients, 20 of whom had PVT. Twentytwo patients were found to have had PVT without evidence of any septic source. They concluded that PVT can be found in a high proportion of patients undergoing abdominal CT scan after RP. It is often associated with pain, fever, nausea vomiting, tenderness, and leukocytosis, and that PVT subtle enough to go undiagnosed has no serious consequences, even when not treated. Pouch failure Lepisto and cols studied the occurrence of pouch failure among 486 patients who had undergone proctocolectomy and ileoanal anastomosis for ulcerative colitis or familial adenomatous polyposis. The other goal was to compare the quality of life in the failure group of 21 patients, the successful group, and the healthy population. The overall failure rate was 5.3 percent 26 ; , including 24 pouch excisions and 2 early deaths 0.4 percent ; . Neither pouchitis, gender, nor diagnosis correlated with pouch failure, but fistula formation p 0.001 ; did. Patients with failure had significant lower quality-oflife scores for physical function, social function, energy and physical role function than healthy population. They concluded that the most common cause of pouch failure is fistula, for instance, stopping azathioprine.

A model infection with Candida albicans was established in mice. The animals were pretreated for 1 week with azathioprine, given dexamethasone, and then infected intravenously with Candida. Mortality for the group given Candida infection alone was 20%, 38% when azathiopr9ne was added, and 50% when dexamethasone and azathioprin were given with infection. The titers of Candida in most mice were 10 per gram of kidney. The rest of the mice were killed at 30 days. At this time, 16% had no evidence of Candida in the kidneys, but 40% of the mice had titers of 106 or more. Mice treated with 5-fluorocytosine had a mortality of less than 4% in 30 days. Five percent of the treated mice killed at 30 days had titers of Candida of 10. Therefore, 5-fluorocytosine increases survival in the presence of continued therapy with azathioprine with or without pretreatment with dexamethasone. The survival is associated with decreased titers of Candida in the kidneys and brethine. Table 3. Chromatographic Mobility of Some Psychotropic and Antiparkinsonian Drugs.

Tochondria with 150 M Aza for 45 min produced no significant change in mitochondrial GSH content 28.8 4.8 nmol GSH mg mitochondrial proteins ; with respect to the control 25.6 1.6 nmol GSH mg mitochondrial proteins ; . Mitochondrial procaspase-3 and bcl-2 levels remained unchanged during Aza 150 M ; treatment 0, 15, 30, or 45 min ; Fig. 6 ; , indicating no leakage of these proteins from mitochondria. Effects of NAC, JNK, and p38 Kinase Inhibitors on the Viability of Rat Hepatocytes Treated with Azathioprine. Cotreatment of rat hepatocytes with Aza 150 M ; and NAC 1 mM ; fully blocked the metabolic activity loss induced by Aza alone Fig. 7A ; . Cotreatment with Aza and CsA 1 M ; partially inhibited the effect of Aza, a result consistent with the effect of CsA on the inhibition of swelling in isolated mitochondria Fig. 7A ; . SAPK and ERK are signaling proteins known to be involved in cell death induced by GSH depletion. In this set of experiments, we examined the effects of pharmacological inhibitors of SAPK and ERK on the metabolic activity of Aza-treated hepatocytes. Figure 7B shows that treatment of hepatocytes with SP600125 a JNK inhibitor ; or SB203580 a p38 kinase inhibitor ; intensely inhibits the loss of metabolic activity elicited by Aza. On the other hand, PD98059 ERK inhibitor ; treatment failed to affect the loss of metabolic activity induced by Aza Fig. 7B ; . Azathiooprine Induces ERK, JNK, and p38 Kinase Phosphorylation in Cultured Rat Hepatocytes. Treatment of cells with Aza 150 M ; in the presence of mitogens 0.1 M insulin plus 20 ng ml EGF ; induced the phosphorylation of p44 42 MAPK ERK 1 2 ; after 3 h of incubation Fig. 8A ; . This effect was reversed by cotreatment with CsA 1 M ; or NAC 1 mM ; , indicating the involvement of the mitochondria in the MAPK activation induced by Aza. The capacity to detect -tubulin structural protein was used as a load control. In a further set of experiments, we explored the Aza effect on JNK and p38 kinase phosphorylation. Treatment of cultured rat hepatocytes with Aza 150 M ; led to increased levels of phosphorylated JNK and p38 kinase Fig. 8, B and C ; . Aza NAC 1 mM ; cotreatment inhibited JNK and p38 phosphorylation and, similarly, diminished the cell metabolic activity loss induced by Aza Fig. 7A ; . However, CsA 1 M ; was unable to block the JNK phosphorylation provoked by Aza. Interestingly, CsA was able to inhibit the p38 kinase phosphorylation induced by Aza. Moreover, in the absence of Aza, PD98059 an ERK inhibitor ; treatment gave rise to increased JNK phosphorylation positive test ; . In conclusion, Aza 150 M ; was shown to induce the early phosphorylation of JNK and p38 kinase, the effect being blocked by cotreat. From a six-month RCT of 311 patients with RA. The authors report that the cost of auranofin was approximately US$692 greater than for the placebo treatment, but the lack of efficacy of auranofin means that it is now rarely used in RA treatment. Cyclosporine, Azathioprine, and D-penicillamine. In a Canadian study, Anis and others 1996 ; conduct a costeffectiveness analysis of cyclosporine use in patients with RA based on the results of a meta-analysis of five RCTs. Their comparators included a placebo control, azathioprine, and Dpenicillamine and analyses based on societal costs or thirdparty payer costs, but the ICERs were expressed as the cost per patient per year improved, so the results are difficult to interpret in the context of a general priority-setting exercise for health expenditures. For the purposes of this chapter, perhaps the study's most useful result was that it found no statistically significant differences between cyclosporine, azathioprine, and D-penicillamine. Given that the existing evidence on cyclosporine, azathioprine, and D-penicillamine indicates similar levels of efficacy, cyclosporine should be used only after less expensive and more effective therapies for the management of RA, including azathioprine and D-penicillamine. Combination Therapy. Verhoeven and others 1998 ; analyze the use of combination therapy using data from the Combinatietherapie Bij Reumatoide Artritis, or COBRA study, conducted in Europe between 1993 and 1995. The study was a 56-week trial that involved treating an intervention group with sulfasalazine, methotrexate, and prednisolone versus sulfasalazine alone as a control. Even though the authors conclude that combined therapy is cost-effective, they qualify the results by stating that the study was probably underpowered. Despite the lack of good cost-effective data, the standard approach to RA treatment is to use combination therapy with DMARDs and to maintain corticosteroids at 7.5 milligrams per day or less if possible. Biologics. A number of trials have shown that the biologic agents tumor necrosis factor inhibitors and others ; are the most effective agents available for reducing inflammation in RA. Their cost US$10, 000 to US$15, 000 per patient per year mode of administration intramuscular, subcutaneous, or by intravenous infusion and potential side effects particularly the reactivation of tuberculosis ; preclude their use in developing countries. Until trials are carried out in developing environments and are combined with robust cost-effectiveness data, we cannot recommend their use. Corticosteroids. Bae and others 2003 ; analyze the costeffectiveness of low-dose corticosteroids for the long-term treatment of RA. They compare the results of corticosteroid and terbutaline.

Aquaculture and Fish Health Research Group, School of Biological Sciences, University of Plymouth, Plymouth, PL4 8AA, UK Fish living in clear, shallow waters may be susceptible to the acute and chronic effects of ultraviolet UV ; radiation, including genomic instability and photocarcinogenesis. Mammalian research has demonstrated that the dietary status of niacin vitamin B3 ; has the potential to influence genomic stability, DNA repair, and the immune system. However, very little information is available for fish, despite the rapid expansion of aquaculture and increased concern for fish health. Therefore, this study investigated the efficacy of niacin NAM ; supplementation in reducing UV-B induced genotoxicity in a fish skin cell line EPC-A1 ; using the Comet assay. The Comet assay was validated using a reference genotoxin EMS ; and a range of UV-2 B doses 0 600 Jm ; . Cytotoxicity was initially assessed using two different cell viability assays trypan blue and Calcein AM EthD III ; with the dual fluorescence assay considered more reliable. Following validation, the potential modifying effects of niacin supplementation 0.18-1.0 mM, 24 h ; on UV-B induced DNA damage was evaluated. Validation studies showed clear dose-response relationships for EMS and UV-B induced DNA damage % tail DNA ; , confirming the sensitivity of the assay for detecting genotoxicity in fish cells. Furthermore, initial results simply that niacin supplementation at the 1.0 mM level significantly reduced UV-B induced DNA damage. This suggests that niacin may be an important dietary factor in protecting fish from environment-induced genomic instability.

Side effects of Azathioprine Of Safety of the National Institutes of Health IARC, 1979 ; . In 1985, antineoplastic drugs were considered, in this program Castegnaro et al., 1985 ; . Since then, several publications have been issued Barek et al. 1987; Monteith et al., 1987; Lunn et al., 1989; Benvenuto et al., 1993; Allwood and Wright, 1993 ; describing the destruction of antineoplastic drugs using acids or strong oxidising agents, such as potassium permanganate, which are not considered acceptable by hospital staff. A new program was thus initiated by IARC with the support of the French Ministry of the Environment and of the National Institutes of Health to systematically investigate the efficiency of 5% sodium hypochlorite and 30% hydrogen peroxide in the degradation of 36 antineoplastic agents. These two reagents were indicated acceptable in a survey conducted among the nurses, pharmacists and members of the Hygiene and Safety Committee of the Hospitals of Montpellier France . Five laboratories from France, the Czech Republic and the United States were involved in the testing of the efficiency of degradation of these compounds and of the residues for mutagenic activity. So far, the results of destruction of cyclophosphamide, ifosfamide and melphalan Hansel el al., 1997 ; and of six anthracyclines Castegnaro et al. 1997 ; submitted for publication ; using sodium hypochlorite, hydrogen peroxide and Fenton reagent were reported. This paper is devoted to the degradation of residual pharmaceutical solutions contaminated by Amsacrine, Azathioprine, Asparaginase and Thiotepa. As in the previous IARC investigations, the effectiveness of the degradation or inactivation methods was determined by HPLC for monitoring the disappearance of the parent compound. Mutagenicity was then chosen as an indicator of potential toxic or genotoxic effects of the degradation products. Amsacrine is an acridine-like intercalating agent [see Fig. l a ; ] currently used as a chemotherapeutic agent for the treatment of acute leukaemia and solid tumours. Therapeutic activity was seen in Hodgkin's disease, hepatoma and epidermoid carcinoma of the oesophagus. Aazthioprine is an immunosuppressant and antineoplastic agent [see Fig. l b ; ] with similar action to those of mercaptopurine to which it is slowly converted in the body. Its main use involves the immunosuppressing properties. Asparaginase is a therapeutic enzyme mainly used in combination with other agents in the treatment of acute lymphatic leukaemia. Thiotepa is a polyfunctional alkylating agent [see Fig. l c ; ] mainly used in the treatment of adenocarcinoma of the breast and of the ovary, and of superficial papillary carcinoma of the bladder. It is also used for controlling intracavity efTusions secondary to diffuse or localised neoplastic diseases of various serosal cavities and has been found effective against lymphosarcoma and Hodgkin's disease. The three above mentioned methods, based on treatment with sodium hypochlorite, hydrogen peroxide and Fenton reagent were investigated on: 1. Also, cases have occurred in patients taking long-term azathioprine, particularly after kidney transplantation. Follow your doctors orders or medicine no data from, for instance, use of azathioprine.
