Ilgenfritz Neto,João; Aydos,Ricardo Dutra; Silva,Iandara Schettert; Takita,Luiz Carlos; Abreu,Antônio Carlos de; Silva,Cynthia Alexia CunhaAbstract Purpose: To compare the use of new cyanoacrylate surgical adhesive associated with macroporous tapes in cutaneous synthesis. Methods: Male Wistar rats with a longitudinal incision of 4cm were used on the back, divided into four groups: GI used octyl-cyanoacrylate (Dermabond®), GII used N-2-butylcyanoacrylate, GIII used octyl-cyanoacrylate and macroporous tape and GIV used N-2-butyl cyanoacrylate and ma...
Oxidative stress effects in the uterus, placenta and fetus of pregnant rats sub...
Silveira,Adriano Silva; Aydos,Ricardo Dutra; Ramalho,Rondon Tosta; Silva,Iandara Schettert; Caldas,Ruy de Araujo; Santos Neto,Abílio Torres dosAbstract Purpose: To evaluate the effects of oxidative stress in pregnant rats submitted to acute and chronic stress, relating to alterations in the uterus, placenta and fetus. Methods: Twenty-four female Wistar albino (Rattus norvegicus), were divided into four groups, for induction of oxidative stress the animals were submitted to cold and physical immobilization. Plasma fasting glucose and MDA were determine...
The aplication of cyanoacrilate surgical glue on skin suture in rats
Ilgenfritz Neto,João; Aydos,Ricardo Dutra; Silva,Iandara Schettert; Ramalho,Rondon Tosta; Ilgenfritz Júnior,João; Campos,Gerson Gattats Orro deAbstract Purpose: To compare the use of a new cyanoacrylate-based surgical glue and suture with sepa-rate points in skin wounds closure. Methods: Thirty-six rats were subjected to a 4cm dorsal longitudinal incision. Twelve were sub-jected to simple suture with polyamide 6-0, 12 rats underwent wall synthesis using Dermabond(r) and 12 was performed cutaneous synthesis with N-2-Butyl-Cyanoacrylate. Twelve of each ...
Doppler velocimetry in fetal rats exposed to enoxaparin and unfractionated hepa...
Senefonte,Flavio Renato de Almeida; Aydos,Ricardo Dutra; Oliveira,Vanessa Marcon de; Bósio,Marco Antonio Costa; Figueiró-Filho,Ernesto AntonioAbstract Purpose: To evaluate the effects of enoxaparin and unfractionated heparin (UFH) administered in prophylactic and therapeutic doses on fetal vessels in healthy pregnant Wistar rats, according to Doppler velocimetry measurements. Methods: Fifty animals were assigned to one of five groups: controls (saline), prophylactic and therapeutic enoxaparin (1 and 2 mg/kg/day, respectively), and prophylactic and th...
Ischemic Postconditioning Assessment in the Liver of Rats Undergoing Mesenteric...
Santos,Carlos Henrique Marques dos; Aydos,Ricardo Dutra; Nogueira Neto,Ed; Miiji,Luciana Nakao Odashiro; Cassino,Pedro Carvalho; Alves,Isadora IshaqAbstract Introduction: Ischemic postconditioning is a method that shows evidence of efficacy in minimizing reperfusion injury; however, its effectiveness in preventing injuries in distant organs is still unknown, especially in those who have undergone mesenteric ischemia and reperfusion. Objective: To evaluate the effect of ischemic postconditioning in preventing reperfusion injury in the liver of rats submitte...
Evaluation of Pulmonary Reperfusion Injury in Rats Undergoing Mesenteric Ischem...
Santos,Carlos Henrique Marques dos; Aydos,Ricardo Dutra; Nogueira Neto,Ed; Miiji,Luciana Nakao Odashiro; Cassino,Pedro Carvalho; Alves,Isadora IshaqABSTRACT INTRODUCTION: Some publications have demonstrated the presence of lung reperfusion injury in mesenteric ischemia and reperfusion (I/R), but under to diverse methods. Postconditioning has been recognized as effective in preventing reperfusion injury in various organs and tissues. However, its effectiveness has not been evaluated in the prevention of lung reperfusion injury after mesenteric ischemia and ...
Pentoxifylline and prostaglandin E1 action on ischemia and reperfusion of small...
Brasileiro,José Lacerda; Ramalho,Rondon Tosta; Aydos,Ricardo Dutra; Silva,Iandara Schettert; Takita,Luis Carlos; Marks,Guido; Assis,Peterson Vieira dePURPOSE: To investigate the action of pentoxifylline (PTX) and prostaglandin E1 (PGE1) on ischemia and reperfusion of small intestine tissue in rats, using immunohistochemical analysis. METHODS: Thirty-five Wistar rats were distributed as follows: group A (n=10): subjected to intestinal ischemia and reperfusion for 60 min, with no drugs; group B (n=10): PTX given during tissue ischemia and reperfusion; group C ...
Importance of duration and number of ischemic postconditioning cycles in preven...
Santos,Carlos Henrique Marques dos; Aydos,Ricardo Dutra; Nogueira Neto,Ed; Miiji,Luciana Nakao Odashiro; Cassino,Pedro Carvalho; Ahmed,Isadora IshaqPURPOSE: To evaluate the effect of ischemic postconditioning (IPC) on intestinal mucosa of rats subjected to ischemia and reperfusion process comparing two cycles of reperfusion and ischemia lasting two minutes each and four cycles of reperfusion and ischemia lasting 30 seconds each METHODS: Thirty Wistar rats were distributed into three groups: group A (10 rats), ischemia (30 minutes) and reperfusion (60 minut...
Correlação entre produção agrícola, variáveis clínicas-demográfcas e câncer de ...
Silva,João Francisco Santos da; Silva,Ageo Mário Cândido da; Lima-Luz,Laércio; Aydos,Ricardo Dutra; Mattos,Inês EcheniqueResumo Fatores de risco para câncer de próstata são pouco conhecidos. O objetivo deste estudo foi explorar correlações entre variáveis relativas à produção agrícola, ao uso de serviços de saúde e sociodemográfcas e às taxas de mortalidade por câncer de próstata entre 2005-2009, nos estados brasileiros. Foi efetuada análise univariada dos dados espaciais para investigação de autocorrelação espacial global das ta...
