Effects of Locally Delivered Morin Hydrate on Iodoacetate-induced Temporomandibular Joint Osteoarthritis in Rats / Efeitos locais da indução de Hidrato de Morina na articulação temporomandibular de ratos com osteoartrite induzida por Iodoacetato

Objectives: morin hydrate has been reported to possess many beneficial pharmacological potentialities including antioxidant and anti-osteoarthritic effects. The anti-osteoarthritic properties of locally administrated morin have not been investigated. The objective of this study is to evaluate the locally delivered morin on the temporomandibular joint osteoarthritis in rat. Materials and methods: thirty young adult female Sprague Dawley rats were randomly arranged into three groups; control, osteoarthritis and osteoarthritis with morin. Both the iodoacetate for osteoarthritis induction and morin hydrate therapy were delivered unilaterally via intra-articular route. Results: morin reduced osteoarthritis manifestations with prominent thickening of both condylar fibrous layer and articular disc accompanied with discal cells hypertrophy that ultimately acquired chondrocytes features. The condylar cartilage matrix showed enhancement of extracellular matrix production with morin administration. Discussion: the present studyhas elucidated antiosteoarthritic effect of intra articular injection of morin hydrate. Although morin has managed to prevent the propagation and advancing some of the recorded osteoarthritic manifestations; however, it showed some failure in managing others. The administration of morin hydrate modulated the structure of the joint rather than restore it back to its typical configuration. Conclusion: the morin hydrate administration to osteoarthritic animals showed relieve in some of osteoarthritic features and modulated the structure of some joint components to compensate the unhandled manifestations (AU)

Objetivo: Relata-se que o Hidrato de Morina possui diversas potencialidades farmacológicas benéficas, incluindo efeitos antioxidantes e anti-osteoartríticos. As propriedades antiosteoartríticas da morina administrada localmente não foram investigadas. O objetivo deste estudo é avaliar a Morina administrada localmente sobre a osteoartrite da articulação temporomandibular em ratos. Material e métodos: Trinta ratos adultos jovens de linhagem Sprague Dawley foram dispostos aleatoriamente em três grupos: grupo controle, grupo com osteoartrite e grupo com osteoartrite e Morina. Tanto o Iodoacetato para a indução da osteoartrite como a terapia com Hidrato de Morina foram administrados unilateralmente por via intra-articular. Resultados: A Morina reduziu as manifestações da osteoartrite com espessamento proeminente tanto da camada fibrosa condilar como do disco articular acompanhado de hipertrofia das células discais que acabaram por adquirir características condrócitas. A matriz da cartilagem condilar mostrou um aumento da produção de matriz extracelular com administração de Morina. Discussão: O presente estudo elucidou o efeito antiosteoartrítico da injeção intra-articular de Hidrato de Morina. Apesar da Morina ter impedido a propagação e o avanço de algumas das manifestações osteoartríticas registadas, mostrou algumas falhas na manipulação de outras. A administração de Hidrato de Morina modulou a estrutura da articulação em vez de restaurar à sua configuração típica. Conclusão: A administração de Hidratode Morina em animais osteoartríticos mostrou alívio em algumas das características osteoartríticas e modulou a estrutura de alguns componentes da articulação em compensação às manifestações não tratadas.

Occurrence of multidrug resistant (MDR) Campylobacterspecies isolated from retail chicken meats in Selangor, Malaysia and their associated risk factors

@#Aims:Campylobacter infection is one of the leading bacterial food-borne illness and most frequently reported in humans in developed countries. This study was designed to determine the prevalence of multidrug resistant (MDR) Campylobacterand the risk factors associated with their occurrence in broiler chicken meat retailed in markets. Methodology and results:A total of 210 samples consisting of 140 chicken meat and 70 swabs from weighing scales and cutting boards were collected. Isolates were cultured by passive filtration method, identified by biochemical tests and confirmed using PCR assay.Thirty-two(32/210) 15.2% were positive for Campylobacterof which (25/210) 11.9%, (6/210) 2.9% and (1/210) 0.5% were Campylobacter jejuni, C.coli andC.upsaliensis respectively. The isolates showed high resistance to ampicillin (62.5%), enrofloxacin (56.3%) and nalidixic acid (50.0%), while only 3.1% were resistant to streptomycin. Multidrug resistant isolates (resistance to at least one antibiotics in three classes or more) was high at 71.9%. The risk factors significantly (p<0.05) associated with Campylobactercontamination on chicken’smeat included poor workers hygiene {OR: 5.250 (95% CI: 0.988-27.895)}, wearing improper work attire {OR: 2.700 (95% CI: 1.144-6.374)}, poor protective equipment {OR 38.50 (95% CI: 2.915-508.463)}, poor environment/stall hygiene {OR 44.00 (95% CI: 2.193-882.66)}, and using tiled counter top surface {OR 6.667 (95% CI: 0.597-74.506). Conclusion, significance and impact of study:The finding of this study affirmed that lack or poor work hygiene, unclean environmental stall and protective equipment are associated with high occurrence of multidrug resistant Campylobacterspecies isolated from chicken meat

Antibiotic resistance profiles of Staphylococcus pseudintermedius isolated from dogs and cats

Aims: Antibiotic resistance in Staphylococcus pseudintermedius is increasing gradually towards those antibiotics that are frequently used leading to limited therapeutic options due to multidrug resistance. The objectives of the study were to investigate the antibiotic resistance profiles of S. pseudintermedius isolates from pet and stray dogs and cats in Selangor, Malaysia and to detect the resistance genes (mecA and BlaZ) within the isolates. Methodology and results: A total of 200 stray and pet dogs and cats were sampled. The samples were cultured onto Mannitol Salt agar and all the presumptive colonies were subcultured, then identified using biochemical tests and confirmed by PCR assay targeting the nuc gene. The isolates were subjected to antibiotic susceptibility test against 12 antibiotics. Twenty three isolates (11.5%) were positive to S. pseudintermedius (stray cats, 11/50; stray dogs, 9/50; pet dogs, 3/50 and pet cats, 0/50). One hundred percent (100%) of the S. pseudintermedius isolates were found to be resistant to penicillin, erythromycin and tetracycline while they showed 100% susceptible to oxacillin, amoxicillinclavulanic acid, gentamicin, chloramphenicol, vancomycin, ciprofloxacin, enrofloxacin, cephalexin and rifampicin. The blaZ gene which codes for β-lactamases production was found in all of the isolates that were resistant to penicillin but not to methicillin. Conclusion, significance and impact of study: A high number of S. pseudintermedius from dogs and cats developed antibiotic resistance which is a public health concern.

CA125, progesterone & ß-hCG in prediction of first trimester abortion / CA125, progesterona e ß-hCG na previsão de aborto no primeiro trimestre

Introduction: Pregnancy loss is a common medical problem in reproductive-age as more than fifty percent of human pregnancies are aborted before term. The majority are unrecognized occurring before or with the expected next menses. About 10­12 percent of all clinically diagnosed pregnancies are lost as first-trimester or early second trimester. The rate of fetal death after 14 weeks' gestation is much lower than the rate of pre-embryonic and embryonic loss. CA125 is a member of the mucin family glycoproteins. CA125 has found application as a tumor marker or biomarker that its level may be increased in the serum of some patients with specific types of cancers. Some studies detected that the abortion risk is increased in pregnant women with higher CA125 levels. Progesterone belongs to the C21 group of progestogen. Its main source in humans is the corpus luteum. Human chorionic gonadotropin (HCG) is a glycoprotein produced by syncytiotrophoblast. Aim of the work: The aim of this study was to determine the effectiveness of measuring maternal serum -HCG, progesterone, CA125 in prediction of first trimester abortion. Patients: The study included 90 pregnant women attending the ANC clinic in El-Shatby Maternity University Hospital. Patients were divided equally into two groups: Group I: 45 women with threatened abortion, subdivided into 2 subgroups: Subgroup A ­ Cases ended in abortion; Subgroup B ­ Cases continued as normal pregnancies. Group II: 45 pregnant women with normal pregnancy and were further subdivided into two subgroups: Subgroup C ­ Cases ended in abortion; Subgroup D ­ Cases continued as normal pregnancies. Exclusion criteria: (1) Multiple pregnancies; (2) Anembryonic pregnancy; (3) Pregnant women with prior treatment with progesterone; (4) History of endometriosis; (5) Fibromyoma with pregnancy. Methods: After clinical and sonographic examination, 3 mL venous blood have been taken once for estimation of serum level of -hCG, progesterone and CA125 by quantitative ELISA. Results: This is a case­control study. Out of the 90 pregnancies, 15 cases (16.6%) had aborted during follow-up, 9 cases (60%) of them had history of threatened abortion while 6 cases (40%) had no history of threatened abortion. Regarding Serum Progesterone level between studied groups, the calculated p value was <0.001. For Serum HCG, the calculated p value was <0.001. In Serum CA125 the calculated p value was <0.001.(AU)

Introdução: A perda da gravidez é problema clínico comum em mulheres em idade fértil, pois em mais de 50% das gestações humanas ocorre aborto antes do termo. Em sua maioria, tais abortos passam despercebidos; ocorrem antes da próxima menstruação ou juntamente com a próxima menstruação. Cerca de 10-12% de todos os abortos clinicamente diagnosticados ocorrem no primeiro trimestre ou no início do segundo trimestre. O percentual de mortes fetais após 14 semanas de gestação é muito mais baixo do que o percentual de abortos pré-embrionários ou embrionários. Foi constatado que CA125 tem aplicação como marcador tumoral ou como biomarcador, pois seu nível pode aumentar no soro de alguns pacientes portadores de tipos específicos de neoplasias. CA125 é um membro da família das glicoproteínas mucinas. Alguns estudos observaram que o risco de aborto aumenta em gestantes com níveis mais elevados de CA125. Progesterona pertence ao grupo C21 dos progestágenos. Em seres humanos, sua principal fonte é o corpo lúteo. Gonadotrofina coriônica humana (HCG) é uma glicoproteína produzida pelo sinciciotrofoblasto. Objetivo: Determinar a eficácia da determinação, no soro materno, de -HCG, progesterona e CA125 na previsão do aborto no primeiro trimestre. Pacientes: O estudo abrangeu 90 gestantes atendidas na clínica ANC na Maternidade do Hospital Universitário El-Shatby. As pacientes foram divididas equitativamente em dois grupos. Grupo I: 45 gestantes com ameaça de aborto, subdivididas em dois subgrupos: Subgrupo A ­ Casos que terminaram em aborto; Subgrupo B ­ Casos que tiveram continuidade como gestações normais. Grupo II: 45 gestantes com gestação normal, subdivididas em dois subgrupos: Subgrupo C ­ Casos que terminaram em aborto; Subgrupo D ­ Casos que tiveram continuidade como gestações normais. Critérios de exclusão: 1. Gestações múltiplas; 2. Gestação anembriônica; 3. Gestantes previamente tratadas com progesterona; 4. História de endometriose; 5. Fibromioma com gestação. Métodos: Após exame clínico e ultrassonográfico, 3 mL de sangue venoso foram coletados uma vez para estimar o nível sérico de -hCG, progesterona e CA125 por Elisa quantitativo. Resultados: Este é um estudo de casos-controle. Das 90 gestações, durante o seguimento ocorreram 15 (16,6%) casos de aborto; nove (60%) tinham história de ameaça de aborto, seis (40%) não tinham história de ameaça de aborto. Com relação ao nível sérico de progesterona entre os grupos estudados, calculamos p < 0,001. Para o nível sérico de CA125, calculamos p < 0,001.(AU)
