4.15 ROLE OF TUMOR NECROSIS FACTOR RECEPTORS TNFRS ; IN A TNBS ANIMAL MODEL OF COLITIS Carmencita Rojas-Cartagena1, Idhaliz Flores2, Caroline B Appleyard3, 1Physiology, Ponce School of Medicine, P.O.Box 7004, Ponce, PR, 00732-7004, 2Microbiology, Ponce School of Medicine, P.O. Box 7004, Ponce, PR, 00732-7004, 3Physiology, Ponce School of Medicine, P.O. Box 7004, Ponce, PR, 00732-7004 TNF- is known to play an important role in IBD; however, the pathophysiological role of its receptors is still unclear. Aim: To measure mRNA and protein levels of TNF- and TNFRs in a rat model of colitis. Methods: Colitis was induced by intracolonic administration of TNBS. Control rats received the ethanol vehicle. Rats were sacrificed 72 hrs later and samples were collected. TNF- and TNFR protein levels were measured in plasma and peritoneal fluid PF ; by ELISA. RT-PCR was performed to measure TNF- and TNFR gene expression. Expression levels were analyzed by densitometry. Results: Protein levels of sTNF p 0.05 ; , sTNFRI p 0.01 ; , and sTNFRII p 0.01 ; in PF were significantly increased in experimental rats. Plasma sTNFRII levels correlated with both macroscopic damage and sTNFRII PF levels p 0.05 ; . TNF-, TNFRI, and TNFRII mRNA expression in the colon of experimental animals was 4-fold p 0.001 ; , 3-fold p 0.05 ; , and 4-fold p 0.001 ; , higher than in controls, respectively. Conclusions: Increased expression of TNFRs and TNF- in the colon of this rat model of IBD provides further evidence for their involvement in the promotion of inflammation and tissue damage. Increased levels of sTNFRs in the PF of experimental rats, particularly sTNFRII, may be involved in the development of colitis by serving as a reservoir of TNF-, and thus provide a novel therapeutic target.

Gerardo A Hernandez, Caroline B Appleyard, Physiology, Ponce School of Medicine, P.O. Box 7004, Ponce, Puerto Rico, 00732 The ability of bacterial peptides, such as fMLP ; , to enhance inflammatory activity via modulation of cytokine expression in intestinal inflammation is unclear. Aim: To measure the levels of TNF-alpha after administration of fMLP in acute and chronic animal models of colitis. Methods: Rats with acute colitis received fMLP 2.5mM i.c. ; 2 hours after administration of TNBS 30mg ; . Chronic "reactivated" colitis was induced six weeks later by intravenous administration of TNBS 5mg kg ; , with or without the bacterial peptide at 24 hour time intervals over three days. Controls received TNBS + vehicle. Colons were scored for damage, and TNF-alpha gene expression and protein levels were measured. Results: Administration of fMLP exacerbated both the macroscopic and microscopic damage in the acute model of colitis but not the chronic. TNF-alpha gene expression after administration of fMLP during the acute or chronic phase was not significantly increased. Levels of TNF-alpha protein were significantly higher after administration of fMLP during the acute phase 14.104.06 pg ml ; compared to controls 3.910.93 pg ml; n 46, p 0.05 ; , but not during the chronic phase 3.303.30 pg ml ; Conclusion: Administration of fMLP exacerbated both damage and TNF-alpha levels during the acute phase of colitis, but not during the chronic `relapsed' phase. These results suggest that the role of bacterial peptides during the acute and chronic phase of colitis is different.
Effect on Total Protein Composition. Equal amounts of aqueous extracts from submandibular and parotid glands from control and treated animals were separated on 7.5 to 15% SDS-PAGE gradient gels. SDSpolyacrylamide gels stained with Coomassie blue revealed increased concentrations of a series ofproteins with molecular weights ranging from 14 to 45 kDa and high-molecular-weight glycoproteins of 200 kDa in the parotid gland extract of rats stimulated with either isoproterenol, salbutamol, or dobutamine not shown ; . These additional protein bands stained poorly with Coomassie blue and were colored pink on partial destaining, a feature characteristic of PRPs. The highmolecular-protein band also stained with periodateSchiff's reagent. Parotid gland extracts from rats treated simultaneously with 5-agonist isoproterenol and antagonists propranolol, atenolol, or metaprolol did not show these additional bands. Protein bands in submandibular gland extracts from treated and untreated rats were not significantly different, except that animals treated with isoproterenol, arterenol, or dobutamine showed a prominent protein band with a molecularweight range of approximately 14 kDa. The RSMG mucin bands, observed in gels stained for glycoproteins with periodate-Schiff's reagent not shown ; , showed an increased mobility in submandibular gland extract from both isoproterenol- and dobutamine-treated rats.

Dental services, including routine dental services. A facility must provide or obtain from an outside resource, in accordance with 483.75 h ; of this part, routine and emergency dental services to meet the needs of each resident; may charge a Medicare resident an additional amount for routine and emergency dental services; must if necessary, assist the resident in making appointments; and by arranging for transportation to and from the dentist's office; and promptly refer residents with lost or damaged dentures to a dentist. Guidelines: This requirement makes the facility directly responsible for the dental care needs of its residents. The facility must ensure that a dentist is available for residents, i.e., employ a staff dentist or have a contract arrangement ; with a dentist to provide services. For Medicare and private pay residents, facilities are responsible for having the services available, but they may impose an additional charge for the services. For all residents of the facility, if they are unable to pay for needed dental services, the facility should attempt to find and alternative funding sources or alternative service delivery systems so that the resident is able to maintain his her highest practicable level of well-being. See 483.15 g ; . ; The facility is responsible for selecting a dentist who provides dental services in accordance with professional standards of quality and timeliness under 483.75 h ; 2 ; . "Routine dental services" means an annual inspection of the oral cavity for signs of disease, diagnosis of dental disease, dental radiographs as needed, dental cleaning, fillings new and repairs ; , minor dental plate adjustments, smoothing of broken teeth, and limited prosthodontic procedures, e.g., taking impressions for dentures and fitting dentures. "Emergency dental services" includes services needed to treat an episode of acute pain in teeth, gums, or palate; broken, or otherwise damaged teeth, or any other problem of the oral cavity by a dentist that required immediate attention. "Prompt referral" means, within reason, as soon as the dentures are lost or damaged. Referral does not mean that the resident must see the dentist at that time, but does mean that an appointment referral ; is made, or that the facility is aggressively working at replacing the dentures. Probes: o Do residents selected for comprehensive or focused reviews, as appropriate, with dentures use them? o Are residents missing teeth and may be in need of dentures? o Do sampled residents have problems eating and maintaining nutritional status because of poor oral health or oral hygiene? o Are resident's dentures intact? Proper fit?.
DESCRIPTION Tenecteplase is a tissue plasminogen activator tPA ; produced by recombinant DNA technology using an established mammalian cell line Chinese Hamster Ovary cells ; . Tenecteplase is a 527 amino acid glycoprotein developed by introducing the following modifications to the complementary DNA cDNA ; for natural human tPA: a substitution of threonine 103 with asparagine, and a substitution of asparagine 117 with glutamine, both within the kringle 1 domain, and a tetra-alanine substitution at amino acids 296299 in the protease domain. Cell culture is carried out in nutrient medium containing the antibiotic gentamicin 65 mg L ; . However, the presence of the antibiotic is not detectable in the final product limit of detection is 0.67 g vial ; . TNKase is a sterile, white to off-white, lyophilized powder for single intravenous IV ; bolus administration after reconstitution with Sterile Water for Injection SWFI ; , USP. Each vial of TNKase nominally contains 52.5 mg Tenecteplase, 0.55 g L-arginine, 0.17 g phosphoric acid, and 4.3 mg polysorbate 20, which includes a 5% overfill. Each vial will deliver 50 mg of Tenecteplase. CLINICAL PHARMACOLOGY General Tenecteplase is a modified form of human tissue plasminogen activator tPA ; that binds to fibrin and converts plasminogen to plasmin. In the presence of fibrin, in vitro studies demonstrate that Tenecteplase conversion of plasminogen to plasmin is increased relative to its conversion in the absence of fibrin. This fibrin specificity decreases systemic activation of plasminogen and the resulting degradation of circulating fibrinogen as compared to a molecule lacking this property. Following administration of 30, 40, or 50 mg of TNKase, there are decreases in circulating fibrinogen 4% 15% ; and plasminogen 11%24% ; . The clinical significance of fibrin-specificity on safety e.g., bleeding ; or efficacy has not been established. Biological potency is determined by an in vitro clot lysis assay and is expressed in Tenecteplase-specific units. The specific activity of Tenecteplase has been defined as 200 units mg. Pharmacokinetics In patients with acute myocardial infarction AMI ; , TNKase administered as a single bolus exhibits a biphasic disposition from the plasma. Tenecteplase was cleared from the plasma with an initial half-life of 20 to 24 minutes. The terminal phase half-life of Tenecteplase was 90 to 130 minutes. In 99 of 104 patients treated with Tenecteplase, mean plasma clearance ranged from 99 to 119 mL min and provera, for instance, propranolol mechanism.

The time course of glycogenolysis was followed till 120 min of incubation. Glycogenolysis was followed up by estimation of medium glucose medium levels spectrophotometrically according to an enzymatic glucose assay kit. Nitric oxide production and other biochemical measurements The time course of NO production, cell protein content protein kit Sigma-Aldrich, Czech Republic ; , ALT leakage Biocon, Germany ; from cells into the medium were measured at appropriate time intervals as indicated in the section Results. NO production was determined by measuring the levels of its oxidation products NO2- and NO3- in the culture medium. This was detected colormetrically 540 nm ; by Griess reagent. The nitrite levels were extrapolated from NaNO2 calibration curve. iNOS expression in cultured hepatocytes by RT-PCR The 24-h cultured hepatocytes were used for the reverse transcriptase-polymerase chain reaction RTPCR ; . Total RNA from hepatocytes was isolated by the standard procedure described earlier Farghali et al. 2002 ; for iNOS. The relative level of iNOS mRNA expression was determined after normalization to the -actin signal to account for variability in the amount of RNA that had been extracted from the cells. Statistical analysis All experiments were performed at a minimum 6-8 times in triplicates means of at least of 18-24 values, see results ; with blind samples as the media background. The statistical significance of the difference of mean scores was determined using the unpaired Studens t-test. Results showing p 0.05 were considered statistically significant.
In partially hepatectomized rats Ferrari & Harkness, 1954 ; , but both catecholamines and glucocorticoids are known to facilitate the induction of some liver enzymes, including ornithine decarboxylase Panko & Kenney, 1971 ; , which is markedly increased early in liver regeneration Jainne & Raina, 1968; Russell & Snyder, 1968 ; . Preliminary experiments in this laboratory established that propranolol, a f-adrenergic blocker, did not affect regeneration, but that phenoxybenzamine, an a-adrenergic blocker, did. A dose of 5mg of phenoxybenzamine kg body wt. given immediately before operation prevented the normal induction of ornithine decarboxylase; the effect, which was transient, delayed the peak of induction by 2h. Under these conditions no effects were detected on DNA synthesis. Adrenalectomized rats behaved similarly to phenoxybenzamine-treated animals, showing only 26 % of the usual decarboxylase activity at 4h but no change in thymidine incorporation into DNA at 21-24h. If phenoxybenzamine was given 5-lOh after operation, after decarboxylase induction had taken place, the peak of DNA synthesis was affected. A dose of 5mg of phenoxybenzamine kg body wt. given 9h after operation shifted the peak from 21.5 to 24.5h. Administration of the drug 1 h before the peak had no effect, indicating that phenoxybenzamine does not act directly on the enzymes involved in DNA synthesis. Nuclear histone phosphokinase Siebert et al., 1971 ; is typical of the enzymes induced 12-15h after partial hepatectomy; this induction was delayed by a dose of 5 mg of phenoxybenzamine kg body wt. given at 9h, suggesting that catecholamines facilitate not only the early wave of enzyme induction in regenerating liver but also that of enzymes, particularly those concerned with replication, that are induced later in G, phase. Phenoxybenzamine did not alter the increased pyrimidine uptake detected 1 h after partial hepatectomy and rabeprazole.
Summary: We studied the proportion and fate of tuberculosis patients who were not initiated on treatment initial defaulters ; in Tiruvallur district of Tamilnadu, where DOTS strategy was implemented. These patients were visited to find out the reason for default. Treatment was not initiated in 57 23.5% ; of the 243 sputum positive cases diagnosed in a community survey and 156 14.9% ; of 1049 patients diagnosed in health facility. Men were more likely not to have treatment initiated. The common reasons stated for initial default were unwillingness, symptoms being mild, personal reasons and dissatisfaction. There is an urgent need to improve the patient's perception of treatment and strengthen the health systems' capabilities to reduce initial default.

Overview Lidocaine is mainly metabolized in the liver by CYP1A2 and CYP3A4 to its two major metabolites, monoethylglycinexylidine MEGX ; and glycinexylidine GX ; , both of which are pharmacologically active. Lidocaine has a high hepatic extraction ratio. Only a small fraction 2% ; of lidocaine is excreted unchanged in the urine. The hepatic clearance of lidocaine is expected to depend largely on blood flow. Strong inhibitors of CYP1A2, such as fluvoxamine, given concomitantly with lidocaine, can cause a metabolic interaction leading to an increased lidocaine plasma concentration. Therefore, prolonged administration of lidocaine should be avoided in patients treated with strong inhibitors of CYP1A2, such as fluvoxamine. When co-administered with intravenous lidocaine, two strong inhibitors of CYP3A4, erythromycin and itraconazole, have each been shown to have a modest effect on the pharmacokinetics of intravenous lidocaine. Other drugs such as propranolol and cimetidine have been reported to reduce intravenous lidocaine clearance, probably through effects on hepatic blood flow and or metabolism. When lidocaine is used topically, plasma concentrations are of importance for safety reasons see WARNINGS AND PRECAUTIONS, General; ADVERSE REACTIONS ; . However, with the low systemic exposure and short duration of topical application, the abovementioned metabolic drug-drug interactions are not expected to be of clinical significance when XYLOCAINE Jelly 2% is used according to dosage recommendations. Clinically relevant pharmacodynamic drug interactions may occur with lidocaine and other local anesthetics or structurally related drugs, and Class I and Class III antiarrhythmic drugs due to additive effects. Drug-Drug Interactions Local anesthetics and agents structurally related to amide-type local anesthetics Lidocaine should be used with caution in patients receiving other local anesthetics or agents structurally related to amide-type local anesthetics e.g. antiarrhythmics such as mexiletine ; , since the toxic effects are additive. Antiarryhythmic Drugs Class I Antiarrhythmic drugs Class I antiarrhythmic drugs such as mexiletine ; should be used with caution since toxic effects are additive and potentially synergistic. Class III Antiarrhythmic drugs Caution is advised when using Class III antiarrhythmic drugs concomitantly with lidocaine due to potential pharmacodynamic or pharmacokinetic interactions with lidocaine, or both.

Decreased clearance of drugs or active metabolites normally cleared by the kidney [5]. These pathological changes may act alone or in combination [43]. In chronic liver diseases as cirrhosis, phase I oxidative reactions catalyzed usually by CYP system of liver, metabolic capacity is reduced approximately by 50%. Therefore, the clearance of drugs affected by this system is reduced. This holds true also for several cardiovascular drugs such as digitoxin, lidocaine, propranolol, propafenone, labetalol, metoprolol and verapamil [5]. Invitro studies with microsomes isolated from removed livers of patients with end-stage cirrhosis showed selective reduction in CYP proteins and their activity [44]. Lidocaine systemic clearance has been reported to decrease by about 50 % [45, 46], while that of propranolol by 70 % [5, 43] in cirrhotic patient compared with healthy subjects. On the other hand, verapamil is a high clearance drug with low systemic bioavailability due to extensive presystemic metabolism by the gut wall and the liver. Therefore, the oral bioavailability of verapamil exhibits considerable inter-and intra-individual variability ranging between 26 and 85% and 12 and 48% respectively. In patients with liver cirrhosis, and because of the high extraction of verapamil by the liver, the hepatic elimination of racemic verapamil is reduced by about 50 % [47]. Furthermore, a profound increase in bioavailability of high clearance drugs in chronic liver diseases was observed Table 2 ; . It may be ascribed to the intra-and extrahepatic vascular shunting that will diminish the extent of first pass effect as well as expected reduction of total hepatic blood flow [36]. 1.4.2. Other Diseases Renal diseases, heart failure , thyroid disorders and gastro-intestinal disorders may affect also the pharmacokinetics of cardiovascular drugs leading to wide variability in responses to these drugs. Because digoxin is principally eliminated by the kidney, renal dysfunction is the most important disease state that affects digoxin pharmacokinetics [48]. Heart failure causes reduced lidocaine clearance because of decreased hepatic blood flow secondary to compromised cardiac output [49]. Table 3 summarized some examples of the effect of some disease states other than hepatic disorders on the pharmacokinetic variability of cardiovascular drugs and retin-a.

[1] Negative energy balance plays a major role in the IGF-I response to exercise training Dan Nemet, Peter H. Connolly, Andria M. Pontello-Pescatello, Christie Rose-Gottron, Jennifer K. Larson, Pietro Galassetti, and Dan M. Cooper J Appl Physiol 2004; 96 276-282 : jap.physiology cgi content abstract 96 1 276?etoc #4 What causes genetic adaptations occur as a result of endurance training? Endurance training leads to many adaptational changes in several tissues. In skeletal muscle, fatty acid usage is enhanced and mitochondrial content is increased. The exact molecular mechanisms regulating these functional and structural changes remain to be elucidated. Contractile activity-induced metabolic perturbation has repeatedly been shown to be important for the induction of mitochondrial biogenesis. Recent reports suggest that the peroxisome proliferatoractivated receptor gamma coactivator 1 PGC-1 ; mitochondrial transcription factor A Tfam ; pathway is involved in exercise-induced mitochondrial biogenesis. In the present study, nine healthy men performed two 45-min bouts of one-legged knee extension exercise: one bout with restricted blood flow, and the other with nonrestricted blood flow to the working muscle. Muscle biopsies were obtained from the vastus lateralis muscle before exercise and at 0, 30, 120, and 360 min after the exercise bout. Biopsies were analyzed for whole muscle, as well as fiber-type specific mRNA expression of Myocyte-enriched Calcineurin Interacting Protein MCIP ; -1, PGC-1, and downstream mitochondrial transcription factors. A novel finding was that, in human skeletal muscle, PGC-1 mRNA increased more after exercise with restricted blood flow than in the nonrestricted condition. No changes were observed for the mRNA of NRF-1, Tfam, mitochondrial transcription factor B1, and mitochondrial transcription factor B2. Muscle fiber type I and type II did not differ in the basal PGC-1 mRNA levels or in the expression increase after ischemic training. Another novel finding was that there was no difference between the restricted and nonrestricted exercise conditions in the increase of Myocyte-enriched Calcineurin Interacting Protein MCIP ; -1 mRNA, a marker for calcineurin activation. This suggests that CALCINEURIN may be activated by exercise in humans and does not exclude that calcineurin could play a role in PGC-1 transcription activation in human skeletal muscle [1]. COMMENT: The research above restricted blood flow to the subjects working leg probably by a partial tourniquet resulting in extraordinary ischemia, or extraordinary blood flow inhibition to the working muscles. No I do not recommend this procedure in order to induce gene expression for performance gain except by occasional interval training sessions. This could be imposed through other hypoxic interventions such as rebreathing apparatus devices, which are worn to inhibit airborne oxygen inhalation. Hypoxia training interval sessions either at altitude or with air rebreathing masks may hypothetically induce the PGC-1 mRNA expression desired for adaptations which lead to extraordinary performance gains. We are presently reviewing substrates, which exert influence on gene expression. It is gene expression encoded in the DNA, which controls the rate of mitochondria reproduction and senesence. When gene expression is turned down a notch, performance is reduced 0.37%-0.5% per year. If gene expression can be turned on or up, energyinduced performance rate follows proportionately.

The EPO and some national patent offices in Europe, the admission of selection patents is subject to limitations in most jurisdictions see the EPO and UK Guidelines in Boxes 8, 9, and 10 ; . In Germany, the Bundesgerichtshof has held that even in a relatively large generic group of compounds, disclosure of the group is, to the skilled chemist, fully equivalent to a disclosure of each compound within the group66. Selection inventions in the normal sense of the word may, hence, be regarded as unpatentable in Germany. If a previous patent contains, for instance, a Markush-type claim with a large number of possible compounds without a detailed disclosure, and the compounds claimed in a subsequent patent are not found by simple experiments and show an unexpected advantage, far enough away from the completely disclosed compounds in the previous patent, an issue of inventive step will and sertraline.

Middle and upper-income groups. Rekha Menon, World Bank Task Team Leader for the project, said that it "builds on the ongoing reform process outlined in the government's Medium Term Expenditure Framework and will be implemented in close coordination with other donors. It aims at addressing the most prevalent health concerns, including reducing the high rates of premature mortality, modernising the hospital sector, and improved targeting of social services for Moldova's poorest people." The project has three main components. The first component, Health System Modernisation, builds on on-going reforms in the health sector that form part of the National Health Strategy 20072017. The second component, Social Assistance and Welfare, supports government plans to improve the effectiveness of cash benefits and social welfare services in combating poverty. The third component, institutional support, relates to the provision of institutional support for the implementation of the reform strategies. The project is an integral part of a larger and longer-term programme of the government to improve the efficiency and effectiveness of social spending in Moldova. It is jointly supported by other donors, including the European Union, the Swedish International Development Cooperation Agency, the United Kingdom's Department for International Development, the Council of Europe Development Bank, and relevant UN agencies. The project will be run over a four-year period, from September 2007 to February 2011, and will be implemented by the Ministry of Health as well as that of Social Protection, Family and Child.

Been reported 1, 2, 9, ; . On physical examination, in addition to decreased motor power, the patient may demonstrate decreased or absent tendon reflexes. The sensations and level of consciousness are generally unaffected 2 ; . Our patient was conscious, any important respiratory or cardiac problems haven't been seen, but deep tendon reflexes were absent together with quadriparalysis. Both of the problems improved completely after potassium replacement. In our case, TPP occurred at night after polyuria, vomiting and serious lumber pain following intake of a total of 225 mg diclophenac sodium in about 5 hours. The most frequent electrocardiographic changes were ST segment depression with T wave flattening, sinus tachycardia, and U waves, which are typical for hypokalaemia and thyrotoxicosis. In patients with TPP, sinus arrest and second-degree atrioventricular block 26 ; , ventricular fibrillation 25 ; , and ventricular tachycardia 27 ; have been described. Electrocardiogram of our case showed sinus tachycardia and ST segment depression V 1-4 ; . Hypophosphatemia and hypomagnesemia during paralysis in patients with TPP have been previously reported 1, 28, 29 ; and may contribute to the muscle weakness 30 ; along with hypokalaemia. In our patient, any other electrolyte imbalance other than profound hypokalaemia was not detected. Hypokalaemia is considered to be the most consistent electrolyte abnormality in TPP and a hallmark of the syndrome, along with hyperthyroidism. It has been demonstrated that hypokalaemia is a result of a K shift into cells and that it is not caused by total-body K depletion and exact mechanism is unknown 16, 17, 31 ; . Correction of the hyperthyroid state is the most definitive treatment for TPP. Hyperthyroidism was managed first with a thyroid suppressant methimazole ; and propranolol 1, 3, 5, ; . Potassium administration during an acute attack will shorten the duration of the episode, and treatment with prednisone, potassium supplementation, or spironolactone may prevent attacks in some patients 9, 32, 33 ; . Definitive treatment of hyperthyroidism was achieved with radioactive iodine. Our patient received totally 106 mEq potassium chloride and recovered in about 6 hours after arriving to the hospital. 200 mg day propylthiouracil and 40 mg day propranolol were given orally to our patient and simvastatin.

Nervous system activity.12 Sevoflurane has low blood gas partition coefficient of 0.6 which allows rapid changes in alveolar concentrations and therefore arterial blood pressure can be manipulated promptly. Moreover the arrhythmogenicity with epinephrine is lower than that of halothane and is equal to isoflurane.12 Thus sevoflurane is a suitable inhalational anaesthetic agent for phaeochromocytoma. Case report A 19 year old boy underwent right adrenalectomy. His medical history included, 6 months history of severe headache with palpitations, urgency and increase in frequency of urine. On admission BP was 150 130 mmHg in right arm in supine position. Urinary VMA was 23 mgday-1 normal value is upto 8 mg day-1 ; . Ultrasonography of abdomen revealed right adrenal mass of 6x4 cm. His blood pressure was controlled with phenoxybenzamine 20 mg three times daily TID ; and propranolol 10 mg TID over a duration of 2 weeks. Preoperatively adequate fluids were given to restore the plasma volume. Patient was given tab. diazepam 5 mg orally in the night and on the morning of surgery. Antihypertensive therapy was continued till the morning of the surgery. General anaesthesia was induced with thiopentone sodium 300 mg, fentanyl 100 mg and 4-5% of sevoflurane. Intubation was facilitated with 8 mg of vecuronium. Intubation of trachea was smoothly performed. Maintenance of anaesthesia was done with sevoflurane 2%, oxygen and nitrous oxide. Ventilation was controlled with a peak inspiratory pressure of 15 cmH2O and respiratory rate of 12 breaths min-1.
