The purpose of this study is to determine the association of speaking space of /s/ sound with vertical and horizontal overlaps for two subject groups. Group I comprised 61 subjects with complete permanent dentition and Group II comprised 33 complete denture wearers. They had their mandibular movement determined by using an electromagnetic method. Speaking space of /s/ was obtained from each subject as they were instructed to say the word 'seis' three times. The mean interocclusal distance during /s/ production was considered the speaking space of /s/. Vertical and horizontal incisor overlaps were also measured. The mean value of speaking space of /s/ was 2.22 mm (± 1.38) for Group I and 2.61 mm (± 1.53) for Group II. In Group I, significant correlations were found between the speaking space of /s/ and vertical overlap (r=0.36, P<0.01), and between speaking space of /s/ and horizontal overlap (r=0.45, P<0.01). In Group II, no significant correlation was found between speaking space of /s/ and the overlaps. It was concluded that incisor overlap had a direct influence on the measure of speaking space of /s/ for dentate subjects, but this association was not present for complete denture wearers.

Functional TLR4 expression has been linked to HCC development. TLR4 may serve an important role in HCC development by promoting the malignant transformation of epithelial cells and tumor growth. The consequences might be dependent on the complex signaling networks triggered by TLR4 activation and the tumor microenvironment. The study included 90 consecutive subjects classified into 3 group their age from 40 to 70 years old. Group (I): HCC patients on top of chronic HCV infection. they were 45 patients 30 male and 15 females, their age ranged from 45 to 55 who were subdivided into 3 subgroups according to Barcelona clinic liver cancer (BCLC): Group (Ia): included 8 HCC patients in early stage. (stage A). Group (Ib): included 12 HCC patients in intermediate stage (stage B). Group (Ic): included 25 HCC patients in advanced stage. (stage C). Group (II): 30 Cirrhotic patients with chronic HCV, 21 male and 9 females, their age ranged from 50 to 60. This group was subdivided into 2 subgroups according to Child–Pugh score Group (IIa): included 8 Child–Pugh A. Group (IIb): included 22 Child–Pugh B and C. Group (III): controlled group included 15 normal subjects. 10 male and 5 females, their age ranged from 45 to 60. They were selected to match patients’ groups in demographic and socioeconomic standards. In our study where 15 persons are control showed lower level in TLR4 with mean 1.0±0.2, however 30 patients with HCV and other 45 patients with HCC showed higher level in TLR with mean 2.27±0.6 and 4.2±1.06 respectively. In our study there is statistically significant difference in serum TLR4 level between group (Ia) (2.25±0.5) and other subgroups which shows more increase in serum level of TLR4 in Group IB (3.2-1.06) than Group IA. Also shows more increase in serum level of TLR4 in Group IC (4.0±2.0) than Group IA and IB In our study HCC group showed higher level of LPS with mean 4.5±1.26 however lower in HCV group with mean 2.9-1.0 and least in control group with mean 1.1±0.4 In our study there is statistically significant difference in serum LPS level between group (IA) with mean 3.0±0.5 and other subgroups which shows more increase in serum level of LPS in Group IB with mean 4.4-1.0 than Group IA.

INTRODUCTION: Acetazolamide as inhibitor of carbonic anhydrase, in glaucoma therapy, has an effect on lowering intraocular pressure. In addition to this primary effects, we attempted to determine the effect on the cornea after phacoemulsification. In our study, we determined the effects of systemically applied dose of 500 mg of acetazolamide on the edema, thickness, and corneal morphology after phacoemulsification, with the Anterior Segment Optical Coherence Tomography (AS OCT). MATERIAL AND METHODS: The study included 53 patients who were divided into two groups. Groups were stratified by type of cataract (nuclear), age (62+1.5), preoperative visual acuity (5/60) Snellen table, and preoperative findings on AS-OCT. Phacoemulsification has done the same surgeon, with the same ultrasound probe length using ultrasonic force of the average value of 14 for a period of 72+2.5 seconds. Group of 33 patients were administered systemic acetazolamide at a dose of 250 mg per scheme 01 hours +24 hours after phacoemulsification (group I). Another group of 20 patients did not receive acetazolamide( group II). AS OCT recordings were performed before surgery, 6 hours and 24 hours after surgery. RESULTS: The mean value in both groups was 549+ 9 ?m before surgery. Group I had average value of 648+6 ?m after 6h, and the mean value was 612+4 ?m after 24h. The group II, had a mean thickness of the cornea after 6 hours of 720+5 ?m, and after 24 hours 708+4?m. Morphological changes in the tomograms of the group I showed minimal creases Descemet?s membrane. Postoperative visual acuity was 0,6,24h after the surgery in the I group of patients, and 0,3 in the II group. CONCLUSION: In our study the patients who administered systemic acetazolamide had significant reduction of central corneal thickness. The folds of Descemet?s membrane and endothelial dysfunction in AS OCT tomograms showed less structural changes in group I. Significant better postoperative visual acuity in these patients is probably because of the smaller corneal edema after 24 h, which improves patients? comfort.

The aim of this study was to evaluate the effect of Altresyn® product (progesterone-based product) as a method for synchronization of oestrus in gilts. The gilts were divided into three experimental groups. The synthetic progesterone Altrenogest was fed daily to 39 gilts at 20 mg/gilts for 18 days. In case of the first group (n = 11 gilts) the treatment was performed using only Altresyn product. In group II (n=13 gilts) was administered the prostaglandin hormone (Prosolvin), 0.75 mg at 24 hours after Altrenogest treatment suppression. Group III (n=15 gilts) received one injections of PMSG hormone (Folligon), 500 IU/animal. Gilts were checked for oestrus twice daily and were artificially inseminated. All gilts expressed signs of oestrus between 3 and 6 days after withdrawal of Altrenogest. At the groups that were administered prostaglandin and PMSG there was a shorter duration of oestrus (group III - 26.66 hours, group II - 27.07 hours) compared to group I (28.54 hours).  In this study, pregnancy rate ranged from 45.45% (group I) and 93.33%(group III), while in group II the value slightly exceeded 50% (53.84%). In group I, the mean litter size was 11.6 piglets, in group II the mean value of farrowed piglets was 13.28 and 15 piglets in group III. Regarding the average number of weaned piglets in group I was 8.8, 12 in group II, while for the third group was 13.14. Altrenogest, the active ingredient in Altresyn® is effective for regulating the oestrus of gilts in commercial pig farms.

Background: CIN has gained increased attention in the clinical setting, particularly during cardiac intervention but also in many other radiological procedures in which iodinated contrast media are used. There is at present good clinical evidence from well-controlled randomized studies that CIN is a common cause of acute renal dysfunction.Methodology: This was a prospective study conducted among the patients who underwent coronary angiography and percutaneous coronary intervention in the Department of Cardiology, Dhaka Medical College Hospital during January 2010 to December 2010. A total of 111 patients age range from 25 to 75 years were included in the study. Serum creatinine level at baseline and at the end of 48 hours was done in all these patients. Study population was divided into two groups according to development of acute kidney injury (AKI). Group-I = AKI, Group II = Not developed AKI. Results: AKI developed 11.7% of the study patient. DM and Preexisting renal insufficiency were significantly higher in group I patients. HTN was (61.5% Vs 44.9%) higher in group I but not significantly. History of ACE inhibitor/ARB, NSAID intake and LVEF <40% were significantly higher in group I patients. The mean±SD volume of CM (Contrast Media) were 156.9±44.8 ml and 115.4±30.0 ml in group I and group II respectively, which was significant. The mean±SD of serum creatinine after 48-72 hours of CAG/PCI was 1.4±0.37 mg/dl and 1.1±0.2 mg/dl in group I and group II respectively. The serum creatinine level increased significantly (p<0.05) after 48-72 hours of CAG/PCI in group I. In group II, S. creatinine level increased but not significant (p>0.05). Impaired renal function was found 76.9% and 2.0% in group I and group II respectively. DM, HTN, preexisting renal insufficiency, ACE inhibitor/ARB, NSAIDs, contrast volume (>150 ml), eGFR (<60 ml/min/ 1.73m2) and LVEF (<40%) are significantly (p0.05) associated for CIN development.Conclusion: CIN is an iatrogenic but preventable disorder results from the administration of contract media. Although rare in the general population, CIN occurs frequently in patients with underlying renal dysfunction and diabetes. In patients with pre angiographic normal renal function, the prevalence is low but in pre-existing renal impairment it may pose a serious threat. Thus risk factors are synergistic in their ability to predispose to the development of CIN. A careful risk-benefit analysis must always be performed prior to the administration of contrast media to patients at risk for CIN.

Abstract Background and aims: Gestational diabetes represents a form of diabetes diagnosed during pregnancy that is not clearly overt diabetes. In the last trimester of gestation the growth of fetoplacental unit takes place, thus maternal hyperglycemia will determine an increased transplacental passage, hyperinsulinemia and fetal macrosomia. The aim of our study was that o analyzing the effect of maternal glycemia from the last trimester of pregnancy over fetal weight. Material and method: We run an observational study on a group of 46 pregnant women taken into evidence from the first trimester of pregnancy, separated in two groups according to blood glucose determined in the third trimester (before birth): group I normoglycemic and group II with hyperglycemia (>92mg/dl). Results: The mean value of third trimester glycemia for the entire group was of 87.13±22.03. The mean value of the glycemia determined in the third trimester of pregnancy was higher in the second group (109.17 mg/dl) in comparison to the first group (74.,21 mg/dl). The ROC curve for third trimester glycemia as fetal macrosomia appreciation test has an AUC of 0.517. Conclusions: Glycemia determined in the last trimester of pregnancy cannot be used alone as the predictive factor for fetal macrosomia.

Background: Labor is a naturally occurring physiological process associated with uterine contractions, effacement, dilatation of cervix and descent of presenting part. Drotaverine hydrochloride is a non-anticholinergic isoquinoline derivative which acts by elevating intracellular cyclic Adenosine Mono Phosphate (cAMP) and cyclic Guanosine Mono Phosphate (cGMP) promoting smooth muscle relaxation. Materials and Method: This was a hospital based prospective study on effectiveness of Drotaverine Hydrochloride on enhancing dilatation of cervix and acceleration of active phase of labor. The sample size was 100. Fifty cases of women in active phase of labor received injection drotaverine hydrochloride 40 mg (group i) and fifty cases of women did not receive any drug (group ii) among those at term with singleton pregnancy and vertex presentation. Variables like maternal age, interval between administration of drug and delivery, mode of delivery, apgar score at 5 minutes, NCU (Neonatal Care Unit) admission and neonatal outcomes were recorded. Data analysis was done with the help of SPSS program. Results: The mean interval between drug administration to delivery in primipara and multipara in group i was 3.05 hours and 2.31 hours while in group ii was 4.5 hours and 3.75 hours respectively. The mean interval between drug administration and delivery was shorter in both groups of multipara. In group i, 96% had normal delivery and 4 % had vacuum delivery and in group ii 90% and 10% had normal delivery and vacuum delivery respectively. None of the participants had caeserian section. There were no perinatal mortalities. Conclusion: The administration of drug Drotaverine Hydrochloride is effective in shortening duration of labor with favorable feto-maternal outcome.

Object The purpose of the present study was to evaluate the efficacy of anterior polymethylmethacrylate (PMMA) cement augmentation in instrumented anterior lumbar interbody fusion (ALIF) for patients with osteoporosis. Methods Sixty-two patients with osteoporosis who had undergone single-level instrumented ALIF for spondylolisthesis and were followed for more than 2 years were included in the study. The patients were divided into 2 groups: instrumented ALIF alone (Group I) and instrumented ALIF with anterior PMMA augmentation (Group II). Sixty-one patients were interviewed to evaluate the clinical results, and plain radiographs and 3D CT scans were obtained at the last follow-up in 46 patients. Results The mean degree of cage subsidence was significantly higher in Group I (19.6%) than in Group II (5.2%) (p = 0.001). The mean decrease of vertebral body height at the index level was also significantly higher in Group I (10.7%) than in Group II (3.9%) (p = 0.001). No significant intergroup differences were observed in the incidence of radiographic adjacent-segment degeneration (ASD) or in terms of pain and functional improvement. The incidences of clinical ASD (23% in Group I and 10% in Group II) were not significantly different. There was 1 case of nonunion and 3 cases of screw migration in Group I, but none resulted in implant failure. Conclusions Anterior PMMA augmentation during instrumented ALIF in patients with osteoporosis was useful to prevent cage subsidence and vertebral body collapse. In addition, PMMA augmentation did not increase the nonunion rate and incidence of ASD.

In this study, genotoxic effects of repeated sevoflurane anaesthesia were investigated in rabbits with or without antioxidant supplementation. Twenty-one New Zealand male rabbits were included in the study and randomized into three groups as: placebo treated (Group I), vitamin E supplemented (Group II) and selenium supplemented (Group III). Vitamin E and selenium were given intraperitoneally for 15 days before anaesthesia treatment. Anaesthesia was administered using 3% sevoflurane in 4 L/min oxygen for a 3-hour period and continued for 3 days. Blood samples were collected before anaesthesia (Sample 1), after the first, second and third days of sevoflurane administration (Sample 2, Sample 3 and Sample 4 respectively) and the last samples were taken 5 days after the last sevoflurane administration (Sample 5). Genotoxic damage was examined using the comet assay. The degree of damage is assessed by grading the cells into three categories of no migration (NM), low migration (LM) and high migration (HM) depending on the fraction of DNA pulled out into the tail under the influence of the electric field. The number of comets in each sample was calculated (1 × number of comets in category NM + 2 × number of comets in category LM + 3 ×number of comets in category HM) and expressed as the total comet score (TCS), which summarizes the damage frequencies. In Group I, a significant increase in the mean TCSs was observed for Samples 3 and 4 as compared with Sample 1. However, there were no significant differences between Samples 1, 2 and 5. The mean TCS of Sample 4 was significantly higher than Sample 1, 2 and 3 in Group II. Group III demonstrated no significant mean TCSs for any experimental conditions. Statistical differences were also observed between the groups with significant P values. This experimental study points out the presence of DNA damage with repeated sevoflurane anaesthesia and the genoprotective role of antioxidant supplementation on DNA damage in mononuclear leukocytes of rabbits by highly sensitive comet assay.

Objective: the clinical value of spinal quantitative CT (sQCT) and the structural patterns of the vertebral bone were studied Material and Methods: sQCT was performed on 246 patients with a mean age of 57 years for whom conventional lateral radiographies of the thoracic and lumbar spine were available. All patients were suffering from back pain of unknown etiology. the bone mineral density (BMD) of the midvertebral section of 3 lumbar vertebral bodies was determined by means of single-energy-(SE)-weighted QCT (85 kV). Spongiosa architecture and density profile analyses were made in the axial images. This was contrasted to BMD values ascertained in SE QCT. the mean BMD was compared to the number of fractures and the patients were divided into three groups: group I — no fracture; group II — one fracture; and group III 1 fracture Results: the mean BMD was: 134.3 (74.1–187.5) mg hydroxyapatite (HA)/ml in group I; 79.6 (58.6–114.3) mg HA/ml in group II; and 52.4 (13.1–79.1)mg HA/ml in group III. A significant deterioration in spongiosa structure was found with increasing demineralization: strongly rarefied patterns predominated in the fracture groups II and III Conclusion: sQCT provides a good risk assessment of the occurrence of vertebral body insufficiency fractures
