And it rose to 51 % reduction at 100 mol l concentration of each drugs. Aggregation stimulated with ADP was reduced in the presence of 20, 50 and 100 mol l propranolol by 13 %, 21 % and 31 %, respectively, whereas carvedilol and atenolol were found to be ineffective at these concentrations Figs 5, 6 ; . Calculation of mean inhibitory concentrations i.e. concentrations yielding 50 % inhibition of aggregation ; revealed that both liphophilic drugs tested, carvedilol and propranolol, reduced the platelet aggregation, depending on the stimulus used, in the following rank order of potency: PMA thrombin Ca2 + -ionophore A23187 epinephrine ADP Tab. 1 ; . In comparison to propranolol, the antiaggregatory effect of carvedilol was more pronounced with an exception for ADP-induced aggregation ; . On the other hand, the hydrophilic drug atenolol, applied at the same concentrations, was without effect on the aggregation induced with different stimuli, the fact of which corresponded with the liposolubility indicated by the logarithm of partition coefficient ; , index of molar refractivity and dipole moment of these drugs Tab. 2 ; .

Adrenal Insufficiency in Asthma: An Unusual Cause of Hypoglycemia? 69. Acute HIV infection usually presents some weeks after the infectious contact as a non-specific and self-limited picture, often with few symptoms. Nevertheless, it may present as a more florid clinical syndrome, characterized by fever, asthenia, maculo-papular skin rash, lymphadenopathy, photophobia and odinophagy. Although many patients seek medical care during the acute phase, diagnosis is rarely made due to frequent confusion with mononucleosis or other viral diseases. From the immunopathogenic point of view, this stage of the HIV infection is characterized by high rate of viral replication, with plasma levels that may reach high values and with a relatively genotypic relatively homogeneous viral population. With the development of the immune response within a few weeks of infection, the amount of circulating viral particles decreases expressively, reaching a set point that varies greatly between patients. This set point seem to have an important prognostic value after the acute infection phase regarding the risk of progress towards future symptomatic disease, motivating some researchers to preconize treatment in this phase, in order to decrease this level attained after primary infection and decrease the risk of future illness. However, studies suggest that HIV eradication seems not to be possible with the available drugs, even if used early, and still do not allow to conclude whether the long term benefit would justify treatment at this stage of HIV infection. Therefore, the Ministry of Health's recommendation until now is to not indicate ART at this stage of infection and rosuvastatin. Coreg carvedilol 6.25 mgQ34: following a radial tear to periphery and a dense nucleus, i would: phaco with single radial tear and valsartan. He is not expectorating properly and can drown in his own secretions -10 % patients can go into respiratory failure. Due to cytotoxicity because not all protein bands detected by silver staining after carvedilol treatment were affected data not shown ; . Furthermore, the concentrations tested in these experiments have been previously shown not to be cytotoxic and reversible in a variety of smooth muscle cell proliferation assays Sung et al., 1993 ; . Although carvedilol inhibits the catalytic activity of MAP kinase partially purified from mitogen-stimulated vascular smooth muscle cells, it still is not certain whether carvedilol can have additional upstream effects on another kinase leading to the activation of MAP kinase or an inhibitor of other signal transduction pathways. The later possibility seems plausible because carvedilol also inhibited tyrosine phosphorylation of several protein bands e.g., 75- and 38-kDa bands ; in addition to MAP kinase. However, this inhibition was not a nonspecific effect as carvedilol did not inhibit MAP kinase kinase protein expression of as determined by Western analysis data not shown ; . The precise molecular mechanism for the inhibition of MAP kinase activity is not yet known. However, carvedilol, as well as some of its hydroxylated metabolites, are also potent antioxidants and free radical scavengers, and this activity largely results from the unique carbazol moiety in its structure. Extensive studies in a variety of test systems, including physicochemical, biochemical, cellular and in vivo models, have established the ability of carvedilol to scavenge oxygen-derived free radicals, and these studies have been reviewed recently Feuerstein and Ruffolo, 1995; Yue et al., 1992 ; . As such, redox-sensitive reactions may be sensitive to the antioxidant properties of carvedilol. Additional support for the possibility that the inhibitory effect of carvedilol on MAP kinase activity in vascular smooth muscle may be mediated by its antioxidant properties comes from the observations that reactive oxygen intermediates can stimulate MAP kinase activity in NIH-3T3 cells Stevenson et al., 1994 ; . Furthermore, oxidative stress can activate a number of early genes, including c-fos, c-myc Crawford et al., 1988 ; , c-jun Datta et al., 1992 ; and NF- B Schreck et al and terazosin. 1.

Identifying Factors that Influence Medical Student Participation in an Obstetrics and Gynecology Setting Saeed, F1; Kasi, P2; Kasi, M3; Rizvi, J3 1 Aga Khan University Karachi, Pakistan; 2Akuh, Pakistan; 3Agha Khan University Hospital Karachi, Pakistan Background: Practicing clinical skills is important for all student health care professionals. There are a variety of personal, provider-related, and contextual factors that influence a patient's decision to participate in medical education. Objectives: The primary objective of our study was to identify factors that influence medical student participation in an obstetrics and gynecology setting. Methods: A cross sectional descriptive study was carried out on inpatients admitted in obgyn wards of Aga Khan University Hospital, Karachi, Pakistan. A total of 250 patients consented to be a part of our study response rate~ 90% ; . Results: 83.2% of the people responded `yes' to the query of being seen by a medical student. People who consented were 3.5 times more likely to know that their primary consultant was a teacher at a medical school i.e. they were initially aware that they were in a teaching hospital p-value 0.01 ; . Additionally, people who did consent were 3.5 times more likely to have been admitted because of labor delivery p-value 0.001 ; and 2.7 times more likely to have a monthly income of more than Rs. 20, 000 p-value 0.05 ; . Conclusions: A number of factors have been identified in our study along with proposed solutions. Identification of these potentially modifiable factors in the medical student-patient interaction is important to improve the involvement of medical students in the care of the patients. Explicit course of actions are thus needed for attaining patients' consent for medical students' involvement and gemfibrozil. Carvedilol lisinopril combinationAlthough the blockade of the b-adrenergic receptor was previously considered to be contraindicated in the failing heart, the clinical efficacy of b-blockers has recently been confirmed to improve cardiac performance, slowing disease progression and reducing the incidence of hospitalization in patients with mild-to-severe chronic heart failure [Bouzamondo et al. 2001, Foody et al. 2002]. Carvedilol is a third-generation b-blocker that also blocks the a1-adrenergic receptor and has antioxidant and antiproliferative properties without any intrinsic sympathetic activity. A number of large-scale clinical trials have shown that carvedilol improves the survival rate, as well as attenuating the subjective symptoms by enhancing the left ventricular ejection fraction [Bristow et al. 1996, Colucci et al. 1996, Krum et al. 1995, Olsen et al. 1995, Packer et al. 1996a, 1996b, 2001]. In general, the dose of carvedilol is gradually increased with careful monitoring for any early signs of clinical instability, but no consensus has been established as to how to determine the initial and maintenance dose requirements. A dose-related improvement in cardiac function was also demonstrated, while there are subsets of patients who are compelled to discontinue carvedilol administration due to aggravation of heart failure. On the other hand, it is generally recognized that the monitoring of serum drug levels may help to improve the clinical effectiveness by optimizing efficacy and minimizing toxicity.

Abstract: A buccal patch for systemic administration of carvedilol in the oral cavity has been developed using two different mucoadhesive polymers. The formulations were tested for in vitro drug permeation studies, buccal absorption test, in vitro release studies, moisture absorption studies and in vitro bioadhesion studies. The physicochemical interactions between carvedilol and polymers were investigated by Fourier transform infrared FTIR ; Spectroscopy. According to FTIR the drug did not show any evidence of an interaction with the polymers used and was present in an unchanged state. XRD studies reveal that the drug is in crystalline state in the polymer matrix. The results indicate that suitable bioadhesive buccal patches with desired permeability could be prepared. Bioavailability studies in healthy pigs reveal that carvedilol has got good buccal absorption. The bioavailability of carvedilol from buccal patches has increased 2.29 folds when compared to that of oral solution. The formulation AC5 HPMC E 15 ; shows 84.85 + 0.089% release and 38.69 + 6.61% permeated through porcine buccal membrane in 4 hr. The basic pharmacokinetic parameters like the Cmax, T max and AUCtotal were calculated and showed statistically significant difference P 0.05 ; when given by buccal route compared to that of oral solution.
PRIMARY AND SECONDARY CAUSES OF HYPERLIPIDEMIA The primary cause of hyperlipidemia is the underlying metabolic defects, which have a genetic basis. Primary hyperlipidemias include familial or polygenic hypercholesterolemia, familial combined hyperlipidemia, familial hypertriglyceridemia and rare dyslipidemia's such as dysbetalipoproteinemia.22 The Fredickson World Health Organization classification of lipoprotein phenotype i.e. lipoprotein I, IIa, IIb, III, IV and V ; is used to distinguish the many different types of hyperlipoproteinemia.23 Types I and V are rare while types IIa, IIb, III and IV are more common. This classification is widely used and gives guidance for cholesterol management. Secondary causes of hyperlipidemia are related to disease risk factors and drugs associated with hyperlipidemia. Disease risk factors include diabetes, obesity, hypothyroidism, and post-renal transplantation. Drug risk factors include steroids, diuretics, beta-blockers and immunosuppressants. In addition, diet is also a significant risk factor contributing to hyperlipidemia.24 Given so many causes of hyperlipidemia, the prevalence of hyperlipidemia is large in the population. Blockers is an old one [35] the physiological mechanism remains elusive. At sea level, ventilation depends on V CO2, arterial P CO2 and V D V according to the following formula: V E V CO2 863 [PaCO2 1 V D where V E ventilation, PaCO2 CO2 arterial pressure and V D V tidal volume dead space ratio [1]. In HF, during exercise, hyperventilation is associated with an increased V D V and V CO2 and a lower arterial P CO2 [1, 32]. Carvedilol reduces ventilation during exercise acting mainly on arterial P CO2 [18]. Indeed during constant workload exercise, arterial P CO2 was increased but V CO2 and measured V D V remained unchanged. During the ramp protocol, in order to avoid multiple systemic artery catheterisations, instead of measuring arterial P CO2, we measured its non-invasive equivalent, the end-tidal CO2 pressure PetCO2 ; [27]. As in the constant workload exercise in the ramp protocol, ventilation was lower, V CO2 unchanged and PetCO2 increased. Together, these data suggest that carvedilol reduces hyperventilation by acting mainly on the arterial P CO2, i.e. affecting the ``socalled'' CO2 set-point which is related to chemoreceptor response [32]. Furthermore, the V E V CO2 slope, which is both the best index of the efficiency of ventilation and a strong prognostic indicator independent of peak V O2 [5, 6, 12, 36], is reduced with carvedilol in patients with an abnormal V E V CO2 slope [18]. The value we chose to define an abnormal V E V CO2 slope was 34, which is the mean T 2 S.D. of the V E V CO2 slope in normal subjects; and which has been previously used to define abnormal V E V CO2 slope [18]. Therefore, our observations in normoxia suggest that carvedilol restores or tends to restore a normal pattern for ventilation during exercise in HF through an up-shifting of the CO2 set-point which is possibly due to a reduction in chemoreflex activity. Our results in hypoxia were obtained after acute exposure to hypoxia without any adaptation to simulated high altitude. Results of the present study are in line with previously published data showing a progressive reduction in exercise capacity with altitude increase in HF patients [29]. The greater reduction in exercise capacity, evaluated as the workload reached at peak exercise, vs. peak V O2 is due to an.
