Dexamethasone


We have previously reported that the bile acids chenodeoxycholate CDCA ; , and ursodeoxycholate UDCA ; , decreased PGE1-induced cAMP production in a time and dose-dependent manner not only in hepatocytes but also in non-hepatic cells including dermal fibroblasts. In the present study we investigated the physiological relevance of this cAMP modulatory action of bile acids. PGE1 induced cAMP production in a time and dose-dependent manner. Moreover, PGE1 1M ; , forskolin 1-10M ; , and the membrane permeable cAMP analog, CPT-cAMP 0.1-10M ; decreased dermal fibroblast proliferation in a dose-dependent manner with a maximum inhibition of around 80%. CDCA alone had no significant effect on cell proliferation at a concentration up to 25M. However, CDCA significantly reduced PGE1-induced cAMP production by 80-90% with an EC50 of ~20M. Furthermore, at concentrations 25M, CDCA significantly attenuated the PGE-1-induced decreased cell proliferation. However, at concentrations of 50M and above, while still able to almost completely inhibit PGE-1-induced cAMP production, CDCA, at least in part through an increased COX-2 expression level and PGE2 synthesis, produced a direct and significant decrease in cell proliferation. Indeed, the CDCA effect was partially blocked by around 50-70% by both indomethacin and dexamethasone. In addition, over-expression of COX-2 cDNA wild type resulted in an increased efficacy of CDCA to block cell proliferation. The effects of CDCA on both cAMP production and cell proliferation were similar to those of UDCA and under the same conditions cholate had no effect. Results of the present study underline pathophysiological consequences of cholestatic hepatobiliary disorders, in which cells outside of the enterohepatic circulation can be exposed to elevated bile acid concentrations. Under these conditions, low bile acid concentrations can attenuate the negative hormonal control on cell proliferation resulting in the stimulation of cell growth, while at high concentrations these bile acids provide for a profound and prolonged inhibition of cell proliferation. Intolerance in adult rats exposed to maternal dexamethasone in utero has been associated with elevated expression of hepatic glucocorticoid receptor GR ; and glucocorticoid-sensitive enzymes involved in glucose regulation such as phosphoenolpyruvate carboxykinase and glucokinase 10, 16, 17 ; . Local hepatic availability of glucocorticoids is regulated in part by corticosteroid-binding protein CBG ; , GR, and the enzyme 11 -hydroxysteroid dehydrogenase type 1 11 -HSD1 ; . We have shown previously that repeated maternal glucocorticoid administration resulted in decreased fetal growth and significantly elevated fetal hepatic CBG and 11 -HSD1 levels 25, 26 ; . These data suggest that prenatal exposure to glucocorticoids alters intra-hepatic glucocorticoids levels, potentially contributing to changes in the expression of metabolic enzymes. Furthermore, we have demonstrated that maternal betamethasone administration results in significant increases in offspring insulin responses to a glucose load at 6 mo and 1 yr of age in a pattern that resembles insulin resistance in type 2 diabetes 14 ; . The long-term effects of fetal exposure to glucocorticoids during pregnancy are of direct clinical relevance. Since the first trial in 1972 9 ; , the administration of synthetic glucocorticoids to women threatened with preterm delivery has become standard obstetric practice. Although repeated courses of glucocorticoids in general are no longer recommended 1 ; , recent surveys suggest that clinicians may still be administering multiple courses 12 ; . The long-term effects of antenatal glucocorticoid treatment in humans are unknown. Individuals from the first reported trial of single-course treatment 9 ; are currently being studied, and ongoing randomized controlled trials of repeated treatments have been not been completed. Long-term effects of fetal exposure to glucocorticoids in sheep depend on the route of administration. In early studies, we 8, 15 ; demonstrated that fetal intramuscular injections of synthetic glucocorticoid betamethasone ; significantly improved fetal lung function and did not result in growth restriction. Furthermore, we 14, 24 ; have demonstrated that maternal intramuscular injection of betamethasone significantly altered postnatal hypothalamic-pituitary-adrenal HPA ; axis activity in offspring but direct fetal glucocorticoid injection did not. We 13 ; have since shown that fetal circulating levels of betamethasone after maternal injection differ from those observed after fetal injection. Cumulative exposure of the fetus to betamethasone was higher after fetal injection than after maThe costs of publication of this article were defrayed in part by the payment of page charges.

To the immunosuppressive and the antiinflammatory effect of GC . The effects of IL-1 are also downregulated by GC since GC suppresses the thymocyte comitogenic activity of IL-1 20 ; . We also observed that GC suppresses IL-1induced proliferation of human dermal fibroblasts . Dower et al. 21 ; have recently reported the existence of specific receptors for IL-1 on a variety of both human and murine cell types . We have also demonstrated high-affinity receptors for IL-1 on an EBV-transformed human B lymphocyte cell line that binds IL-la and IL-1, 8 equally well 22 ; . Since GC downregulates the effects of IL-1, we speculated that this may be based on effects of GC on the expression of receptors for IL-1 . Therefore we investigated the effect of GC on IL-1-R expression of human PBMCs . Unexpectedly, our data reveal that GC dramatically increased IL-1-R expression on PBMCs within several hours without any loss in the binding affinity . Materials and Methods Reagents. Prednisolone, dexamethasone, cortexolone 17-hydroxy-l1-deoxycorticosterone ; , progesterone, 17#-estradiol, and testosterone were purchased from Sigma Chemical Co . St Louis, MO ; .

Human rIL-1, B was a generous gift from Dr. Y. Hirai Otsuka Pharmaceutical Co ., Tokushima, Japan ; . Cell Cultures. PBMCs were obtained from PBLs isolated from healthy volunteers by leukapheresis. Mononuclear cells were separated by centrifugation on a Ficoll-Hypaque gradient. To separate T lymphocytes, PBMCs were mixed with 2-aminoethylisothiouromium bromide AET ; Sigma Chemical Co . ; -treated sheep erythrocytes SRBCs ; for 1 h on ice . The rosetting and nonrosetting cells were separated by Ficoll-Hypaque gradient centrifugation . The SRBCs were removed from the rosetting cells by lysis with NH 4Cllysing buffer . The nonadherent rosetting population obtained by removal of plastic adherent cells was demonstrated to consist of 92% Leu 4' and 5% Leu 11' cells as determined by flow cytometry and will be referred to as "T cells" population . The nonrosetting cells included B lymphocytes 12% Leu 12 + ; , monocytes 71% Leu M3 + ; , large granular lymphocytes LGLs ; 13% Leu I I' ; , and rosette-positive cells 4% ; and will be referred to as "non-T cells ." Large numbers of cells enriched in B lymphocytes can be obtained by using a technique known as counter-current centrifugal elutriation . The "lymphocyte" fraction, which consists of small lymphocytes, and an "intermediate" monocyte fraction, which consists of monocytes and large lymphocytes, were isolated from PBMCs by counter-current centrifugal elutriation as described elsewhere 23 ; . Subsequently, the cells in each fraction were separated into T and B cell populations by two times AET-SRBC rosetting of lymphocytes . The nonrosetting cells from the lymphocyte fraction was shown to consist of 65% Leu 12' and 4% Leu M3' cells and will be referred to as the "small B cells, " and the cells from intermediate monocyte fraction consisting of 58% Leu 12', 23% Leu M3', 22% Leu 11', and 5% Leu 4' cells and will be referred to as the "large B cells ." We chose not to use surface Ig as a marker because anti-Ig even Ffab]'2 ; reacts with both human B lymphocytes and monocytes . LGLs were separated from PBMCs as previously described 24 ; . Briefly, PBMCs were depleted of monocytes by adherence on a plastic surface and applied to a nylon wool column, and the eluted cells were then fractionated on a seven-step discontinuous gradient of Percoll Pharmacia Fine Chemicals, Uppsala, Sweden ; at concentrations between 40 and 60% . LGL-enriched preparations collected from the low-density fraction fraction 2 and 3 ; were demonstrated to contain 75-80% Leu 11' cells.

Considering the outcomes from this experiment, it was demonstrated that co-administration of alcohol and naproxen, one of the currently available NSAIDs, augmented the gastric mucosal lesion in comparison to the administration of alcohol or naproxen alone. Subsequently, treatment of DA-9601 that is being developed for targeting a new gastric mucoprotectant was shown to account for the preventative effects on gastric mucosa effectively against the lesion caused by alcohol and naproxen. Besides the effects on quantified gastric lesion, the level of MDA and MPO in DA-9601 treated group exhibited similar level to that in normal control and it was also revealed that DA-9601 contributed to intact maintenance of the gastric mucosa at the extent of normal control on histopathological examination. The well-known etiologies for peptic ulcer can be categorized as follows: eating habits, environmental factors, stress by social life, drinking behavior, smoking, and drugs. Among these causative factors, drug-induced peptic ulcer is increasing dramatically with respect to the overuse of NSAIDs and increased susceptibility of gastric mucosa by single or co-administration of oral anti-coagulants warfarin, phenindione, phenprocoumon, acenocoumarol, anisindione, diphenadione, etc. ; and corticosteroid hormones triamcinolone, dexamethasone, cortisone, hydrocortisone, prednisolone, prednisone ; [18]. It is reported that alcohol is responsible for the hemorrhage of gastric mucosa and edema in submucosal muscle layer by means of direct irritation[19] and also leads to acute gastritis associated with microcircular stasis [20]. Once gastric mucosa is injured, thereby ischemia and decreased level of ATP in gastric mucosa and intervention of microcirculation occurs[21]. Gastric mucosal damage due to chronic ingestion of low concentration of alcohol is generally not discernible on gross examination; however, if gastric mucosa is exposed to an external mucosal irritant, gastric lesion becomes more extensive and consistent with increased susceptibility as well as persistent submucosal microcircular stasis[22]. It was demonstrated that DA-9601 100 mg kg treatment exerted excellent preventative or therapeutic effects on gastric mucosal lesion with action of duration being effective for more than 2 h. It was also well documented that these effects were in accordance with the facilitation of the synthesis of PG by DA-9601. Since aspirin was first synthesized in the year of 1899, a variety of NSAIDs has emerged so far and they are being used as antipyretic analgesics and anti-inflammatory drugs. Nowadays, the market size of NSAIDs is more than 60 billion year, in addition, more extended indications are making the need for NSAIDs to increase[23]. Despite these facts, NSAIDs were reported to cause gastric lesion since 1930s and underlying mechanism was related to the fact that NSAIDs inhibit cyclooxygenase COX ; thereby block the synthesis of PG[24]. More specifically, NSAIDs elicit gastromucosal lesion not only by reducing the physiological role of PG, but also by directly inducing neutrophilic infiltration in gastric capillaries causing subsequent stasis.

Vitamin supplements should only be ingested in situations where intake is inadequate. However, advertisements and companies are now implying that vitamins are `natural health supplements' and that `more is better'. As a consequence, many people are led to believe that taking mega-doses of vitamins frequently is beneficial for health. Generally, a mega-dose is ten or more times of the recommended daily allowance RDA.

According to Sarraille, to ensure compliance with the law's required cap on gifts and incentives offered to medical and health care providers, a company must now develop systems, to the extent they do not already exist, that track the value of items provided from anyone in the company. "There is no de minimus exception in the statute, " he adds. "Arguably, the new policy must include the value of promotional items from sales representatives, peer-to-peer dinners, permitted office lunches, certain educational programs, and activities at national medical conferences, to the extent offered." Moreover, the statute could be interpreted to include volume discount pricing and other pricing incentives, he says. "Manufacturers will need to make their best efforts to carefully evaluate direct and indirect relationships with `health care providers' in order to identify and distinguish capped expenses from those that are exempt, " he says. However, the statute provides no mechanism for requesting clarification, he adds.

Wondered which cells were dying in the lung parenchyma of the treated animals at days 19 and 21. We performed double-labeling experiments using the TUNEL assay and the antibody MNF-116. The antibody MNF-116 recognizes a wide range of cytokeratins 21 ; . In lung parenchyma it binds specifically to the apical surface of type II epithelial cells 13 ; . Two cells that were positive for both labels are shown in Fig. 3a. In addition, sections were double-labeled for cell death TUNEL ; and for basement membranes laminin-1 ; to distinguish between interstitial and epithelial cells. Figure 3b shows a TUNEL-positive cell that is sitting in a niche of two alveolar septa. The basal and lateral surfaces, but not the apical surface, of this cell are covered by a basement membrane. After verifying by laser-scanning microscopy that the gap in the basement membrane disappeared in the zone where the apical surface comes into contact with the lateral surface of the cell, we concluded that this type of cell represents a type II epithelial cell. Figure 3c shows a TUNEL-positive cell that is distantly surrounded by basement membranes. Again, after verification by laser-scanning microscopy, we concluded that this type of cell represents an interstitial cell. Comparing sections of treated and untreated animals at days 19 and 21, we were not able to detect any significant difference in the kind of cells dying; only the relative number of dying cells was reduced see above; Fig. 2 ; . Cell proliferation. Kauffman and coworkers 14 ; described a peak of cell proliferation at day 4 in rats that steadily declines afterward. Using the monoclonal antibody MIB-5, which recognizes the Ki67 antigen 11, 12 ; , we observed the described peak of cell proliferation in the untreated animals at the same day. Surprisingly, the number of proliferating cells rose sharply from day 3 to day 4 and not gradually from day 1 to day 4 as expected from previous studies 14 ; . The sharp rise of cell proliferation takes place just at the beginning of the septation of the distal airways. In the dexamethasone-treated group cell proliferation was drastically reduced at days 24 Fig. 4 ; . Later, at days 1036, no significant difference between treated and untreated animals was detected anymore Fig. 4; data not shown for days 1636 ; . Tissue transglutaminase. The extracellular expression and action of the enzyme tissue transglutaminase is also considered to be a marker for the maturation of the alveolar septa. It takes place toward the end of the third postnatal week in rats at the same days when the peak of programmed cell death was observed 24, 25 ; . At days 436 we studied the intracellular and extracellular expression of tissue transglutaminase as well as the appearance of the enzyme product, the -Glu- Lys cross-link, using the same antibodies and immunohistochemical techniques as in the original study 25 ; . Similarly to the lack of structural alteration of the lung parenchyma in the treated animals toward the end of the third week, we were not able to detect any significant difference between the treated and untreated animals in the expression pattern and action of.

Introduction Hypertension is firmly established as a major independent risk factor for the development of occlusive vascular disease. Accordingly a range of antihypertensive drugs have been developed for long term management of the condition. They include calcium channel blockers CCBs ; , diuretics, angiotensin converting enzyme ACE ; inhibitors and beta blockers. It is recognised that lowering blood pressure BP ; by any means reduces the risk of developing occlusive vascular disease [1]. However it is increasingly appreciated that certain antihypertensive agents have direct antiatherosclerotic actions in addition to and independent from their BP lowering effects [2, 3]. Since the various classes of antihypertensive drugs act via different mechanisms it follows that they have the capacity to influence different aspects and phases of the atherosclerotic process. This article assesses calcium channel antagonism as a potential direct antiatherosclerotic strategy. It proposes upper limits to the efficacy of current CCBs based on recent findings concerning plasticity in Ca 2 signalling pathways. Further, it reviews emerging data on recently identified classes of Ca2 + channels which may represent targets in the future. The main focus is on vascular smooth muscle cells SMCs ; , the clinical target of CCBs. CCBs in BP lowering and early occlusive vascular disease CCBs inhibit the passage of extracellular Ca2 + through the L-type voltage operated Ca2 + channel also denoted CaV1.2 ; of the SMC plasma membrane [4]. They act as direct vasodilators, lowering peripheral vascular resistance. They are generally well tolerated and exhibit a low side-effect profile. These points, and 4 and valsartan.

300 Other studies have reported the antiemetic potential of phenothiazine in cats McCarthy and Borison 1984 ; and metoclopramide in dogs Hikasa et al. 1986 ; . Xylazine has been widely used as a sedative in animals prior to performing many procedures, such as radiography, catheterization, and ultrasonography. However, emesis is frequently reported after xylazine administration in cats, which may distress the animal and also increase the risk of aspiration pneumonia. Centrally acting drugs are more effective than peripherally acting drugs. Phenothiazine derivates e.g. acepromazine ; and metoclopramide inhibits the chemoreceptor trigger zone and increases gastric tone and peristalsis, both of which inhibit emesis Hikasa et al. 1992a ; . On the other hand, only one study reported that pre-treatment with dexamethasonw 4 or 8 mg kg, IM ; decreased the number of emesis and prolonged latency of xylazine induced emesis in cats Ho et al. 2001 ; . The present study was conducted on cats to determine which of these three drugs have an antiemetic effect on xylazine-induced emesis and nevirapine.

Alkyl radical R ; , and a hydfoperoxide ROOH ; . This is thought to result in a sequential increase in the volume of alkyl radicals fig. 6 ; . In contrast, in the normal brain homogenate, there is little or no increase in chemiluminescence values over 30-40 minutes of contact with air oxygen -- suggesting that there has not occurred pathological free radical reaction fig. 7 ; . With regard to the mechanism of photon emission in chemiluminescence, it is known from the spectral peaks that singlet oxygen, particularly the 'Ag oxygen, is involved. 2630 Since the chemiluminescence measurements are made in the air, it is also known that the predominant singlet oxygen is produced by the breaking of the peroxy radical ROO * ; subsequent to the hydroperoxide and alkyl radical ROOH and R * ; .28-31 This experiment was attempted to make clear the effect of vitamin E, glucocorticoid and mannitol as free radical scavenger in lipid peroxidation. Vitamin E7'13 is known as an important free radical scavenger, due to its lipid solubility and occurrence in membranes. The protective effect of vitamin E is due to its ability to scavenge free radicals, such as superoxide anion or singlet oxygen, as well as its ability to scavenge lipid peroxy radicals, such as methyl linoleate radical. Glucocorticoid14"18 is widely used for brain edema due to its stabilizing effect of cell membrane. Its pharmaceutical mechanism has been reported as suppressor of extrication of arachidonate acid by impeding phospholipase A2. The present data of chemiluminescence and its emission spectroanalysis are able to interpret the mechanism of glucocorticoid as radical scavenger in the breakdown of lipid hydroperoxide besides impeding phospholipase A2. So far some reports dn glucocorticoid as free radical scavenger or inhibiter of autoxidation has published. Suzuki and Yagi 1973 ; reported that pretreated dexamethasone decreased the levels of edema and lipoperoxide products in cryogenic injury rat brain using the thiobarbituric acid assay.20 Seligman and Demopoulos 1979 ; have shown that glucocorticoid significantly decreased lipoperoxide products on UV irradiation-irritated liposorhe membrane in vitro.19 Mannitol1-5-6-8 has been widely used to decrease cerebral volume and it has been reported to increase cerebral blood flow. On the other hand, Seki 1983 ; reported that mannitol caused an increase of rCBF. The following estrogen dosage philosophies are popular for treatment of male-to-female transsexuals: adjust estrogen to achieve a serum estrogen level in the normal range of a female; more or less ignore the serum androgen level the body cannot make good use of more estrogen than a female would naturally generate androgens do not directly compete with estrogens for estrogen receptor sites a higher level of exogenous estrogen might cause adverse effects adjust estrogen for gross empirical results while paying extra attention to health adjust estrogen to achieve a serum androgen level in the normal range of a female; more or less ignore the serum estrogen level the body might be able to make good use of more estrogen than a female would naturally generate androgens might compete with estrogen for estrogen receptor sites high levels of exogenous estrogen over a limited period less than 3 years, do not usually cause adverse effects in a person with a very healthy liver and videx.

O010-09 An assessment of dexamethasone sensitivity in the olfactory bulbectomized rat model of depression Thomas J. Connor, National University of Ireland, Dept. of Pharmacology, Galway, Ireland, Email: thomas.connor nuigalway.ie A. Harkin, J. P. Kelly The olfactory bulbectomized OB ; rat has been developed as an animal model of depression. It has been reported that OB rats display increased hypothalamic pituitary adrenal HPA ; axis activity compared to their sham operated counterparts, thus modeling the hypercortisolaemia observed in depressed patients Cairncross et al., 1977; Song et al., 1994 ; . Objective: To further explore the HPA-axis in the OB rat, the present study sought to examine dexamethasone sensitivity in this animal model using both in vivo and in vitro approaches. Method: Male adult Sprague-Dawley rats 175-200g upon arrival ; were used. Surgery was performed under chloral hydrate anasthesia 375 mg kg; i.p. ; and involved either the removal of the olfactory bulbs or a shamoperation. Animals were allowed a 4 week recovery period prior to measurement of dexamethasone sensitivity. Both sham operated and OB rats were challenged with the synthetic glucocoticoid dexamethasone 100 g kg; i.p. ; and plasma corticosterone concentrations measured 12 hr later. In a second study, heparinized blood samples were obtained and the sensitivity of concanavalin A-induced lymphocyte proliferation and cytokine IFN- & IL-10 ; production to in vitro dexamethasone 10-10-108 M ; was investigated. Results: Administration of dexamethasone in vivo suppressed circulating corticosterone concentrations; however the degree of suppression observed did not differ between sham operated and OB rats.

When the cells were incubated with LPS 50 ng.mL-1 ; plus IFN-c 50 U.mL-1 ; , baseline current was not detected, but application of L-arginine caused an increase in the current with a lag time of 10 s3 min. Between 15 and 30 min after the addition of L-arginine, the response showed the maximal value of 14725 pA p 0.001, n 11 ; , which corresponds to an NO concentration of 11620 nM in the medium [16], and the subsequent electrical current remained elevated during a 2-h observation period fig. 2b ; . To assess whether the observed response was associated with type II NOSmediated release of NO, after the response of electrical current reached a plateau, aminoguanidine 10-5 M ; , a specific inhibitor of NO synthesis through type II NOS [20], was added to the medium. As shown in figure 2c, addition of aminoguanidine rapidly decreased the current by 769% p 0.001, n 9 ; in PAMs treated with LPS plus IFN-c. The rat PAMs were incubated for 12 h with LPS plus IFN-c in the presence of erythromycin 10-710-4 M ; , clarithromycin 10-710-4 M ; , josamycin 10-710-4 M ; , amoxycillin 10-4 M ; , cefaclor 10-4 M ; or dexamethasone 10-7 M ; . As shown in figure 2d and figure 3, exposure of cells to erythromycin, clarithromycin or josamycin at 10-4 M reduced the electrical current induced by LPS plus IFN-c by 7310, 816%, or 849%, respectively p 0.001, n 11 for each drug ; . Dexametnasone 10-7 M ; likewise inhibited the production of NO by 964% p 0.001, n 11 ; , but amoxycillin and cefaclor at 10-4 M had no effect. The inhibitory effects of the macrolide antibiotics on NO release were dose-dependent, the concen.
