We examined how acupuncture affected the blood flow of muscle, kidney, stomach, small intestine, brain, lung, heart, spleen and liver. Wistar rats anesthetized with urethane (n = 27) were allocated into the control (n = 10), ST-7 (Hsia-Kuan, n = 10) and LI-4 (Hoku, n = 7) groups. To measure organ blood flow, colored microspheres (CMS) were injected through a catheter positioned in the left vent...

Electrophysiological studies of a patient with cephalic tetanus, manifested by trismus and unilateral facial palsy, revealed that the trismus resulted from strictly unilateral masseter spasm which stopped during sleep, a normal silent period in the involved masseter muscles, initially prolonged distal latency of the paretic orbicularis muscles, and abnormal continuous muscle activity in the par...

The most widespread animal model to investigate Duchenne muscular dystrophy is the mdx-mouse. In contrast to humans, phases of muscle degeneration are replaced by regeneration processes; hence there is only a restricted time slot for research. The aim of the study was to investigate if an intramuscular injection of BTX-A is able to break down muscle regeneration and has direct implications on t...

Histochemical properties, muscle fiber cross-sectional area, muscle fiber length, and the oxidative capacity of masticatory muscles of female rhesus monkeys were assessed following alteration in functional length by an intraoral appliance or by detachment of the muscle. Experimental groups received the appliance only (A); the appliance and subsequent detachment of the masseter (AD); the applian...

Unilateral posterior crossbite is a malocclusion disease that involves morpho-functional characteristics of masseter muscle; normal or increased activity contralateral muscle and reduced the ipsilateral during unilateral have been shown. Since extracellular matrix plays key role in mechano-transduction transmitting forces contraction, aim present study was to analyse behaviour this type through...

AIM To investigate effect of capsaicin-evoked masseter-muscle pain on intramuscular blood-flow (BF) at rest and during contractions. METHODS Eight healthy men (22-31 years) participated. BF was measured with Laser Doppler (Moor Instruments, UK) using a single-fibre probe inserted into the right masseter. Three BF probes were attached to the skin above right and left masseter and the right-mid...

26 The orexins (Orexin-A and orexin-B) are neuropeptides which are secreted from 27 neurons in the lateral hypothalamus, which participate in the regulation of feeding 28 behavior. It remains to be determined, however, how the orexins exert their effects on 29 feeding behavior, including masticatory movements. To this end, we analyzed food 30 intake behavior and masticatory muscle activity usin...

A 32 year old Indian male presented with progressive painless swelling of both jaws and temporal regions. The patient was otherwise asymptomatic and denied history of bruxism. Clinical examination revealed bilateral non-tender swelling over both mandibles and temporal fossae (Figure 1). Systemic examination and dental examination was normal. magnetic resonance imaging (mrI) of the head revealed...

The purpose of this study was to test whether the tongue position affects the electromyographic (EMG) activities of masticatory muscles. We recorded the EMG activities of the masseter and anterior temporalis muscles in 10 skeletal Class I adults. Tongue position was monitored by two pressure transducers embedded in the midpalatal region and the lingual flange of a custom-made acrylic monoblock....

The orexins (orexin-A and orexin-B) are neuropeptides that are secreted from neurons in the lateral hypothalamus and that participate in the regulation of feeding behavior. It remains to be determined, however, how the orexins exert their effects on feeding behavior, including masticatory movements. To this end, we analyzed food intake behavior and masticatory muscle activity using video analys...
