The power outage caused by decay-like fracture of composite insulators significantly impacts the grid. In this paper, a fractured insulator 500 kV transmission line is taken as research object. detailed observation core rod and silicone rubber housings, discharge results, temperature rises, electric field distribution are obtained. (a) has abnormal heating on exposed sheath surface, ambient hum...

The search for the ideal material to be used in frontalis suspension procedures to correct congenital ptosis has been going on for many years and continues to this day. This makes me believe that perhaps there is no ideal suspensory material other than autogenous fascia lata. To add a little perspective on this problem, I reviewed a publication from 1984 in which, along with my co-editor Leonar...

background peripheral nerve repair is often complicated by fibroblastic scar formation, nerve dysfunction, and traumatic neuroma formation. use of silicone may improve outcomes of these repairs. in this study, we tried to evaluate effectiveness of silicone gel on rats’ sciatic nerve repair, axon regeneration and scar formation around and in the nervous tissues. methods this experimental study w...

Purpose: To report the efficacy of frontalis suspension using a silicone rod or preserved fascia lata for patients with blepharospasm who exhibit persistent symptoms and visual dysfunction unresponsive to botulinum injections.Methods: The clinical records five (10 eyes) essential underwent were reviewed. Patients continued eyelid-opening difficulties despite prior administration toxin included....

Silicone has been utilized as a carrier material for sustained release system of lipophilic drugs. Extensive studies revealed that drug release rate is influenced by factors such as physicochemical properties of the drug and additives.(1-5)) When a lipophilic drug is highly potent at low concentrations, the drug release rate should be strictly controlled so as to avoid side effects. In this stu...

OBJECTIVE To evaluate use of covered-rod (CR) silicone implants containing ivermectin for long-term prevention of infection with Dirofilaria immitisin dogs. ANIMALS 145 adult male and female dogs. PROCEDURES Dogs received implants of different sizes, and ivermectin concentrations and serum ivermectin concentrations were monitored for 16, 57, and 56 weeks, respectively, in 3 preclinical dose...
