Allogenic platelet-rich plasma in induced ulcers in rat's cornea / [Plasma rico em plaquetas alogênico em úlceras de córnea induzidas em ratos]

The objective in this study was to evaluate the clinic effect of applying allogenic platelet-rich plasma (PRP) heated or not, for treating cornea ulcers, including the dosage of PDGF-BB in the cornea. The ulcers were induced, standardizing the left eye from 81 rats (Ratus norvegicus, albinus variety), assigned randomly into three groups (N=27): control group (CG) which did not receive any topic treatment; heated PRP group (GA) and PRP group (GP), which received topical treatment every eight hours for five days. Each group underwent evaluation at 24 hours (M1), three days (M3) and five days (M5). The clinical exam evaluated the opacity, vascularization and corneal repair. The corneal PDGF-BB was dosed through the ELISA method. The corneal opacity was decreased in PRP-treated animals (GA and GP) and corneal repair time reduced when compared to CG at M1 and M5. Furthermore, GP showed greater vascularization at M3 compared to M1. Applied allogenic PRP eye drops, heated or not, speed up corneal healing, and reduce corneal repair time. However, the corneal PDGF concentration was not altered in any of the treatments.(AU)

Objetivou-se avaliar o efeito clínico da aplicação de plasma rico em plaquetas alogênico (PRP) aquecido ou não, no tratamento de úlceras de córnea, como a dosagem de PDGF-BB na córnea. As úlceras foram induzidas, padronizando-se o olho esquerdo de 81 ratos (Rattus norvegicus, variedade albinus), aleatoriamente, nos três grupos (N = 27): grupo controle (CG), que não recebeu nenhum tratamento tópico; grupo PRP aquecido (GA) e grupo PRP (GP), que receberam tratamento tópico a cada oito horas, durante cinco dias. Cada grupo foi subdividido em 24 horas (M1), três dias (M3) e cinco dias (M5). O exame clínico avaliou a opacidade, a vascularização e o reparo corneano. O PDGF-BB corneano foi dosado pelo método Elisa. Houve diminuição da opacidade da córnea nos animais tratados com PRP (GA e GP) e diminuição do tempo de reparo da córnea em comparação com CG, M1 e M5. Além disso, foi observada maior vascularização no GP no momento M3 em relação ao M1. A aplicação de colírios de PRP alogênico, aquecidos ou não, acelera a cicatrização da córnea, além de reduzir o tempo de reparo da córnea. No entanto, a concentração de PDGF na córnea não se alterou em nenhum dos tratamentos.(AU)

A safer endovascular technique for pre-operative embolization of juvenile nasopharyngeal angiofibroma: avoiding the pitfalls of external carotid artery – internal carotid artery anastomoses

Intra-arterial embolization of juvenile nasopharyngeal angiofibroma (JNA) prior to surgical resection is the preferred approach to minimize blood loss during surgical resection of the tumor. However, the presence of external carotid artery–internal carotid artery (ECA-ICA) anastomoses may hinder complete tumor embolization due to the associated risk for embolic complications. Here, we evaluate the use of a balloon-assisted embolization (BAE) technique in the treatment of JNA. We conducted a retrospective review of JNA patients who underwent tumor embolization with injection of Onyx in a single session between 2013-2018. All cases displayed tumor arterial supply from ECA and ICA circulations on 2-D catheter angiograms. Procedural and surgical outcome data were analyzed. Results are given as mean±- standard deviation (range). Among 9 patients with JNA, all were males and mean age was 14.1±6.3 years (range, 9-29 years). The mean tumor volume embolization was 84.4±12.4% (range, 60-100%) and in 89% patients ≥80% of tumor volume embolization was achieved. There were no embolization-related complications reported. During surgical resection of the tumor there was a low average surgical blood loss of 722±651.5 mL (range, 50-2,000 mL) and the mean procedure time was 282.6±85.4 mins (range, 151-403 mins). In this series, the BAE technique showed to be a safe and effective approach to achieve successful tumor embolization while avoiding embolic complications and effectively reducing the risk for blood loss during surgical resection.

Cleaning Efficiency of Root Canals using Differ ent Rotary Instrumentation Systems: A Comparative In vitro Study

Background: Smear layer is always formed during the instrumentation process due to the action of endodontic instruments during the shaping process and it should be removed as it might decrease the overall success of endodontic therapy. Aim of the study: To compare the cleaning efficiency of different rotary Ni-Ti systems: ProTaper Next, Xpendo Shaper and WaveOne Gold by assessing their ability to remove the smear layer from root canals walls. Methods and materials: A total of 24 palatal roots of maxillary molars were used in this study and randomly assigned into 3 groups (n=8) as follows: Group 1: instrumentation with ProTaper Next system (Dentsply Maillefer, Switzerland), Group 2: instrumentation with Xp-endo Shaper system (FKG Dentaire, Switzerland) and Group 3: instrumentation with WaveOne Gold system (Dentsply Maillefer, Switzerland). The samples were irrigated with 5.25% NaOCl. All samples were then examined by scanning electron microscope (SEM) at the center of the coronal, middle and apical thirds. The data was statistically analyzed using Kruskal Wallis and Mann-Whitney U tests. Results: ProTaper Next files showed a lower average mean of smear layer when compared to WaveOne Gold and Xp-endo Shaper files at the coronal third. No significant differences between the average means of smear layer were found at the middle and apical thirds. Conclusion: None of the tested groups showed a completely smear layer free root canal walls. In general, ProTaper Next files showed the best performance at the coronal third. All the files showed comparable performance at the middle and apical thirds.

Protective and therapeutic potentials of Dunaliella salina on aging-associated cardiac dysfunction in rats

Objective: To investigate the possible protective and/or therapeutic potentials of Dunaliella salina (D. salina) biomass, its carotenoid and polar fractions on cardiac dysfunction associated with D-galactose (D-GAL) induced aging in rats. Methods: Aging associated cardiac dysfunction was induced in rats by injection of D-GAL (200 mg/kg; i.p) for 8 weeks. D-GAL injected rats were treated with two regimens; protective regimen where D. salina biomass (250 mg/kg), its carotenoid (250 μg/kg) and polar (250 μg/kg) fractions were given orally for two weeks concurrently with D-GAL injection as well as treatment regimen where the three treatments were given orally for 28 consecutive days after D-GAL injection. Results: D-GAL injection for 8 weeks was accompanied with dramatic electrocardiographic changes as well as profound elevation in serum levels of homocysteine, creatinine kinase isoenzyme and lactate dehydrogenase in addition to the reduction of the cardiac content of glucose trasporter 4. D-GAL also induced reduction in cardiac superoxide dismutase activity and elevation of inducible nitric oxide synthetase and interleukin-6. On the other hand, oral administration of D. salina carotenoid fraction as well as the total biomass significantly attenuated the D-GAL-induced disturbances in the above mentioned parameters where the protective regimen appeared more successful in controlling the manifestations of cardiac dysfunction. The histopathological examination further emphasized the promising results. Besides, the HPLC analysis of the carotenoid fraction of D. salina revealed the presence of 2.31％ β-carotene. Conclusions: D. salina carotenoid fraction as well as the total biomass ameliorate D-GAL-induced aging associated cardiac dysfunction which is attributed to the potent antioxidant activity of β-carotene.

RESUMO As duas espécies de espinheira-santa Maytenus aquifolium Mart. e Maytenus ilicifolia Mart. ex Reissek pertencentes à família Celastraceae e têm sido intensamente exploradas nas populações nativas devido seu alto valor medicinal. O grande interesse pela espinheira-santa é para o tratamento de gastrites, úlceras gástricas e duodenais. O efeito antiulcerogênico está relacionado com a presença de polifenóis totais, mais especificamente com os taninos. Este trabalho teve como objetivo comparar o teor de taninos entre essas duas espécies cultivadas no Horto Medicinal do Refúgio Biológico Bela Vista - RBBV da Itaipu Binacional no município de Foz do Iguaçu, PR - Brasil. Foram realizadas duas coletas com intervalo de um mês para cada espécie e para a quantificação foi realizada a análise por espectrofotometria segundo a Farmacopeia Brasileira V. Os resultados foram analisados através do teste de variância (ANOVA) e a diferença no teor de taninos foi evidenciada pelo teste Tukey, a 5% de nível de significância empregando-se o software SISVAR. Foram obtidos em média 0,61% para o lote 1 e 2 de Maytenus aquifolium e (3,90%) para Maytenus ilicifolia, resultando em uma média de 84,35% de taninos a mais para Maytenus ilicifolia em comparação com Maytenus aquifolium concluindo assim que as espécies não devem ser intercambiáveis.

ABSTRACT The two species of (espinheira-santa) Maytenus aquifolium and Maytenus ilicifolia, which belong to the Celastraceae family, have been intensively explored in native populations, due to its medicinal potential. The great interest in the espinheira-santa is due to its effectiveness on the treatment of gastritis, gastric and duodenal ulcers. The antiulcerogenic effect is related to the presence of phenolic compounds, more specifically the tannins. This study aimed to compare the tannin doses between these two species grown in the Medicinal Garden of Bela Vista Biological Refuge - RBBV of Itaipu in the city of Foz do Iguaçu, PR - Brazil. Two trials were conducted with one month interval, for the quantification of the tannins by a spectrophotometry, according to the Brazilian Pharmacopoeia V. The results were analyzed through the analysis of variance (ANOVA) and the difference in the tannins doses was demonstrated in a Tukey test at 5% level of significance employing the SISVAR software. It were found 0.61% of tannins for lot 1 and 2 of Maytenus aquifolium, and 3.90% for Maytenus ilicifolia, which represents 84.35% more tannin at Maytenus ilicifolia than at Maytenus aquifolium. Therefore, the species should not be interchanged.

Molecular characterization of a haemagglutinating and non haemagglutinating rabbit haemorrhagic disease viruses from Egypt

Rabbit viral haemorrhagic disease [RVHD] is a highly contagious, peracute and acute viral disease of both wild and domestic rabbits caused by rabbit haemorrhagic disease virus [RHDV]. RHDV is considered as a haemagglutinating virus; however, there is a growing evidence for presence of non haemagglutinating RHDV strains. In this study, two RHDVs have been characterized. The two viruses were selected from ten different infected rabbit flocks. One of them had haemagglutination [HA] activity and the other one lacked HA activity. HA test was carried out on both isolates at 4[degree]C using human red blood cells [RBC] type 'O'. RT-PCR was performed on the liver samples of the ten infected rabbit flocks using specific primers targeting VP60 gene. The obtained partial VP60 gene sequences of the two selected strains were aligned with other haemagglutinating and non haemagglutinating strains of RHDV in the world, including ''RHDVa'' strains as France 99-05, France-Reu-00, Germany-Triptis and China TP. Phylogenetic analysis showed that the two strains were genetically different. Haemagglutinating strain was similar to Rainham strain which is low haemagglutinating virus while non haemagglutinating strain was similar to whn-1 strain which is non haeagglutinating virus. The study confirmed presence of non haemagglutinating RHDV in rabbits reared in Egypt and suggested that VP60 might be related to HA activity

Antioxidant and Cytotoxic Activities of Gmelina arborea ROXB. Leaves.

Aims: The leaves of Gmelina arborea (ROXB.) (Family Verbenaceae) are widely used in the folklore to treat various types of diseases. In this study, the antioxidant and cytotoxic activities of different methanolic extracts and the derived subfractions of 90% methanolic extract of this plant were evaluated. Methodology: The antioxidant activity was carried out via three different quantitative assays as well as qualitative one. Total phenolic was determined via Folin-Ciocalteu and total flavonoid via AlCl3 assays. The cytotoxic activity was carried out via brine shrimp test and toward human cancer cell line; HepG2 using Sulphorhodamine-B assay. The 90% methanolic extract was fractionated using pet. ether then the 90% defatted methanol undergoes fractionation using (CHCl3, EtOAc and n-BuOH). Results: The antioxidant results showed that the; DPPH antioxidant activity was (19.20, 14.10 and 28.94 μg/ml); total antioxidant capacity was (412.69, 518.45 and 390.41; mg AAE /g extract); reducing power was (0.649, 0.715 and 0.396; 200 mg/ml) and total phenolic was (330.22, 400.66 and 244.76; mg GAE/g extract), respectively for 90% methanol, n-BuOH and EtOAc. The cytotoxic results showed that the; mortality of brine shrimp larvae (LC50) against different dosages of defatted 90% methanol, n-BuOH and EtOAc respectively was (158.48, 39.81 and 199.52; μg/ml) and the results of HepG2 assay showed that n-BuOH fractions have cytotoxic activity with IC50 ≤ 20 μg/ml (IC50 = 17.3 μg/ml) which falls within the American Cancer Institute criteria followed by 90% methanol and EtOAc (IC50 = 22.1 μg/ml). Conclusion: It was concluded that Gmelina arborea extracts possess a powerful antioxidant and cytotoxic activities.

Tumour-like presentation of central nervous system tuberculosis: a retrospective study in Kingdom of Saudi Arabia

To differentiate the tumour-like presentation of central nervous system [CNS] tuberculosis [TB] from CNS tumours. We conducted a retrospective chart review of all cases of CNS TB seen at King Abdulaziz Medical City, Jeddah, between January 2002 and January 2012. No symptoms or signs of pulmonary or systemic TB were found. Of the 125 patients with CNS TB, 9 [7.2%] presented with clinical and radiological features suggestive of a brain tumour. A diagnosis of tuberculoma was established either intraoperatively in frozen sections [three patients] or postoperatively when the masses were resected [six patients]. After surgery, seven patients recovered after receiving anti-TB treatment; one patient died, and another developed a severe neurological deficit. CNS TB is a great mimicker of brain tumours, and the index of suspicion should be high, especially in endemic areas. A diagnosis is based on clinical presentation and the results of investigations. In patients with CNS TB that present with a mass lesion, a biopsy should be taken to avoid morbidity and mortality from an unnecessary surgical intervention. Greater use should be made of magnetic resonance spectroscopy in the evaluation of brain space-occupying lesions, and CNS TB should be included in the differential diagnosis of such lesions in all areas endemic for TB. The absence of constitutional or pulmonary symptoms of TB is deceiving. More nationwide epidemiological studies are needed to establish guidelines for early detection and successful outcomes of this rising health problem

Memory boosting effect of citrus limon, pomegranate and their combinations

Memory is greatly influenced by factors like food, stress and quality of sleep, hence present study was designed to evaluate the effect of Citrus limon and Pomegranate juices on memory of mice using Harvard Panlab Passive Avoidance response apparatus controlled through LE2708 Programmer. Passive avoidance is fear-motivated tests used to assess short or long-term memory of small animals, which measures latency to enter into the black compartment. Animals at MCLD showed highly significant and significant increase in latency to enter into the black compartment after 3 and 24 hours respectively than control, animals at HCLD showed significant increase in latency only after 3 hours. Animals both at low and moderate doses of pomegranate showed significant increase in test latency after 3 hours, while animals at high dose showed highly significant and significant increase in latency after 3 and 24 hours respectively. There was highly significant and significant increase in latency in animals at CPJ-1 combination after 3 and 24 hours respectively; however animals received CPJ-2 combination showed significant increase in latency only after 3 hours as compare to control. These results suggest that Citrus limon and Pomegranate has phytochemicals and essential nutrients which boost memory, particularly short term memory. Hence it may be concluded that flavonoids in these juices may be responsible for memory enhancing effects and a synergistic effect is observed by CPJ-1 and CPJ-2 combinations

Adult intussusception. An overlooked diagnosis in the emergency department

To study the appropriate method of diagnosis and management in adult intussusception [AI] focusing on the clinical manifestations, diagnostic tools, and management of this rare disease. This retrospective study reviewed and analyzed the demographic data, clinical features, diagnosis, management, and pathology reports of all adult patients [18 years of age and older] with a diagnosis of intussusception admitted to Sohag University Hospital, Sohag, Egypt, and Najran Armed Forces Hospital, Najran, Kingdom of Saudi Arabia [KSA] from January 2004 to August 2012. From 2004-2012, 14 patients with AI were diagnosed and treated. Ages ranged from 22-63 years. Ten patients [71.4%] were males. Thirteen patients [92.9%] presented with abdominal pain. All patients were diagnosed after a CT scan, and confirmed at laparotomy. The lead point was found in all, except for 2 patients. Ileo-ileal and jejuno-jejunal intussusceptions represented most of our cases [64.3%], followed by ileocolic [28.5%], and colocolic [7.1%]. The most common causes were Peutz-Jeghers polyps [5 cases], submucosal lipoma [2], and malignancy [2]. Surgery was the treatment option in all except one patient. Postoperative complications occurred in 3 cases [21.4%]. One patient died 28 days postoperatively due to septic shock and multiorgan failure. Owing to its rarity, AI needs a high index of suspicion especially in patients attending ERs with recurrent abdominal pain. A CT scan is of prime importance in the diagnosis, and surgical treatment is the preferred method of management

Inactivation of avian influenza virus using commercial chemical disinfectants in small scale poultry production

Two commercial chemical disinfectants which are commonly used currently in the Egyptian markets were tested individually for effectiveness against highly pathogenic avian influenza virus [HPAIV]A/chicken/Egypt/13VIR3729/4/2013 [H5N1]., which currently hit the Egyptian poultry farms at 2013, The tested agents were sodium hypochlorite 5% available chlorine [NaOCL] and PERACLEAN 5%[registered][Peroxyacetic Acid4.9% and hydrogen peroxide 26.5%]. The test was performed in accordance to the guidelines of American environmental protection agency [EPA], using a carrier test with surfaces [coupons] designed specially to mimic the poultry house floor and made from concrete cement, [under dirty condition resembled phase two, step two of European Committee for Standardization [CEN]. At room temperature which mimic the field condition in the Egyptian poultry farms, both sodium hypochlorite with concentration [250ppm], and PERACLEAN 5%[registered]with concentration [1%], were not able to inactivate the virus after 5 minutes contact time, while inactivation was achieved within 30 minutes contact time, which proved one of the golden rules when applying a disinfectant, that was allowing the increase of contact time between the disinfectant and influenza virus

Cervical gouty myelopathy in two cases at King Abdulaziz medical city

Gout is a rheumatological disorder found exclusively in human species. It is caused by deposition of crystals of monosodium urate in joints, cartilages, tendons, and soft tissues. Involvement of the spine, however, is rare. In this report, we describe two patients presented to King Abdulaziz Medical City in Jeddah with clinical features of cervical myelopathy, including neck pain, L'hermitte phenomena, quadriparesis and sensory deficit [shoulder level]. Magnetic resonance imaging confirmed the presence of cervical cord compression with intrinsic cord signal abnormalities. Both patients had laminectomy and intraoperatively; severe canal stenosis was identified. A whitish cheesy material was noticed causing significant root compression. The pathology was diagnostic of gout. In this article, we present two difficult cases with interesting clinical, radiological and pathological findings. We emphasize on the importance of early diagnosis to prevent morbidity

Have magnesium sulfate, acetic acid, meprobamate and fluoxetine an anti-arthrogenic activity?

Atherosclerosis is a progressive inflammatory disorder of the arterial wall that is characterized by focal lipid rich deposits of atheroma with possible correlation with sedative hypnotics in decreasing atherogenesis. This study was performed in Al-Kadhimiya teaching hospital from February 2009 to June 2009 on sixty healthy males who were allocated to six groups. Each group was given one of the following agents: Magnesium sulfate [MgSo4], acetic acid, Meprobamate, Fluoxetine in addition to Simvastatin and water. Clinical manifestations like [arterial blood pressure, radial pulsation], lipid profiles [serum cholesterol, triglycerides, HDL, LDL and VLDL] total free radicals and platelets function tests are the parameters used in this study. All the tested agents reduce both the serum cholesterol concentration and total blood free radicals significantly; also they decrease both platelet count and adhesion test significantly. Both MgSo4 and Meprobamate lowered blood pressure and serum triglyceride concentration significantly, at the same time HDL concentration significantly changed by Fluoxetine when these parameters measured before and after treatment for 15 days. MgSo4, acetic acid, Meprobamate and Fluoxetine were found to have anti-arthrogenic activity and the possibility to be used clinically in atherosclerosis

Assessment of thyroid functions in patients with chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease [COPD] is no longer considered to [COPE]; affect only the lungs and airways but also the rest of the body. The systemic manifestations of Thyroid hormones; COPD include a number of endocrine disorders, such as those involving the pituitary, the thyroid, the gonads, the adrenals and the pancreas. The severity of airway obstruction in chronic obstructive pulmonary diseases [COPD] is associated with the impairment of thyroid gland function. This study was carried out to evaluate thyroid abnormalities in patients with COPD and relationship between pulmonary function tests, arterial blood gases and thyroid functions. Serum free triiodothyronine [ft3], free thyroxin [ft4], and thyroid stimulating hormone [TSH] were measured in 50 patients with COPD and 50 healthy volunteers [control group] and its relation to some ventilatory function tests [FEV1/FVC, FEV1, FVC%, and FEF25-75] and ABG parameters [PH, Paco2, Pao2, Hco3 and O2 saturation] were studied. There was no significant difference in mean levels of TSH, FT3 and FT4 between COPD and control group. The mean values of free T3, free T4, and TSH were within normal limits in both groups however, free T3 values in the case group were toward upper normal limits and the mean values of free T3 were increased in the case group compared to their values in the control group. The mean values of free T3 of the cases were significantly increasing with increased severityof COPD. Significant negative correlations were present between free T3 levels and pulmonary function tests of the cases. Significant negative correlations were present between free T3 levels and both PaO2 and SO2 of the cases and also show a significant positive correlation between free T3 levels and PaCO2 of the cases. Thyroid function tests among COPD patients showed a significant increase of the mean free T3 values and a non significant decrease of the mean free T4 and TSH values compared to the control group. With increasing severity of COPD, the mean free T3 values showed a significant increase. Significant negative correlations were noticed between free T3 levels and both PaO2 and SO2 of the cases. A significant positive correlation was observed between free T3 levels and PaCO2 of the cases. Significant negative correlations were observed between free T3 levels and pulmonary function tests of the cases

effects of magnetic resonance imaging examinations on vital signs

Magnetic resonance imaging [MRI] is used to produce detailed sectional images, and considered a safe tool compared to the x-ray based medical diagnostic techniques, as general radiography, and computed tomography [CT],because MRl does not employ ionizing radiation but uses radiofrequency [RF] fields. The main objective of this study was to determine the effects of MRI examinations on the main vital signs [blood pressure, body temperature, cardiac pulse rate and respiratory rate]. A sample of fifty patients with ages between [18-68] years old underwent MRI studies for different anatomical regions. The vital signs have been measured before and after the MRI examination. The results showed that there was significant increase in body temperature and no significant relationship was detected in pulse rate, blood pressure and respiratory rate

effect of different levels of protein on biochemical change of diabetic rats

The prevalence of Type 2 diabetes is increasing and has become a major public health problem. The amelioration of insulin resistance independent of weight loss was with the consumption of a high protein diet. Thirty-five adult male albino rats, Sprague Dawley strain, weighting 170+/- 1 0g were used. Then, rats were divided into five groups, 7 rats each with similar total body weight and were housed individually in the wire cage. Group 1 [control negative] were fed soybean protein isolate [12% protein] for 28 days. Other rats were injected by alloxan to induce diabetic, Second group: Diabetic control group [control positive] was fed .soybean protein isolating [12% protein]. These rats were randomly chosen, after injection with alloxan by six hours and used for estimation serum glucose. Other three groups fed three percentage of protein [10, 15, 20 % soybean protein isolate]. The result showed that the group of 10% c?id 15% soybean protein isolate, relative liver weight were significantly increase [P<0.05] when compared with negative control. While 20% soybean protein isolate showed a reduction in relative kidney weight with negative control .Also others groups showed significantly higher [P<0.01] when compared with control negative. Blood glucose showed a gradual decreased with the increase of protein as 15% and 20% level. The results of those groups were significantly lower [P<0.01] when compared with control positive. High protein diet improve lipid profile and glucose level, while kidney function was shown higher level of creatinine and urea than positive control
