Methylmethacrylate and Atrioventricular Conduction in Dogs
Acta Anaesthesiologica Scandinavica, 1984The effect of intravenous methylmethacrylate (MMA) on atrioventricular conduction times was studied in dogs, utilizing His‐bundle electrograms. Dogs were anesthetized with halothane or enflurane; then MMA in a dose causing minimal to profound hemodynamic changes was administered and His‐bundle electrograms, and arterial, pulmonary artery, and central ...

Methylmethacrylate as an adjunct in spinal instrumentation
The Journal of Bone & Joint Surgery, 1977Sixteen patients with scoliosis were treated with Harrington-rod instrumentation supplemented by methylmethacrylate fixation at the distraction sites to reduce the possibility of dislodgement of a hook due to inferior bone stock or the patients' inability to cooperate postoperatively because of mental insufficiency or involuntary-movement disorders ...

The Journal of Bone & Joint Surgery, 1978
To determine possible deleterious effects of methylmethacrylate vapor on mouse gestation, pregnant mice were exposed to average vapor concentrations of 1330 parts per million for two hours twice daily during Day 6 through Day 15 of pregnancy. A slight increase in the average weight of the fetuses of the exposed mothers were demonstrated but no other ...

Methylmethacrylate upper ureteral obstruction
Urology, 1986A case of upper ureteral obstruction caused by methylmethacrylate cement after fixation of an L2-L3 vertebral fracture is reported. The probable mechanism, radiographic findings, and management of this complication are reviewed.

The Effect of Methylmethacrylate on Complement Activity
Clinical Orthopaedics and Related Research, 1977The effect of methylmethacrylate on the activity of the complement sequence has been investigated in vitro by standard hemolysis techniques. It was demonstrated that concentrations of methylmethacrylate monomer as low as .25% inhibit the reactions of the complement sequence by 50%.

Local neurotoxicity of methylmethacrylate monomer
Toxicology Letters, 1983A technique was devised which allowed a controlled exposure to methylmethacrylate liquid on rat tail skin. The procedure was repeated 3 h daily for 8 weeks. This caused keratolysis without ulcerations in the exposed skin and abnormal muscle responses to stimulation of the rat tail motor nerves by a skin electrode through the treated area after 4 weeks ...

Methylmethacrylate Metabolism in Man
Clinical Orthopaedics and Related Research, 1979Methylmethacrylate, the monomeric component of the polymethylmethacrylate cement used in orthopedic surgery, has been shown to undergo hydrolysis to methacrylic acid during hip replacement operations. Circulating levels of methacrylic acid were comparable with those of methylmethacrylate.

The hardnesses of poly(methylmethacrylate)
Tribology International, 1996The paper describes an experimental study of the normal and scratch hardnesses of a poly(methylmethacrylate). The deformations have been introduced using hard steel cones of a range of included cone angles. The influence of the state of interfacial lubrication is examined and rationalized.

The Effect of Methylmethacrylate on Fracture Healing
Clinical Orthopaedics and Related Research, 1976Fractures were created in the femur of dogs by dividing the midshaft with an airdriven saw. Immobilization was achieved with a four-hole compression plate. No methylmethacrylate supplementation was used in the control groups. In the three experimental groups methylmethacrylate was added to the internal fixation by placing it on the endosteal ...

Journal of Nanoscience and Nanotechnology, 2006
As most of polypeptides are marginally stable, a mild formulation procedure would be beneficial for the activities of these drugs. The objective of the present study was to develop a novel pH-sensitive nanoparticle system that was suitable for entrapment of hydrophilic insulin but without affecting its conformation.
