Piezoelectricity in the Intervertebral disc

Effects of Morphine Dependency on Intervertebral Disc in the Rat

Background: A large proportion of patients presenting with lumbar disc disease are opium addicts in our region. It was, therefore, hypothesized that morphine might affect the intervertebral disc. We investigated the histological findings of morphine dependency on intervertebral discs in rat. Methods: Forty NMRI adult male rats (230-250 g) placed on ordinary diet and received aqueous solution of...

The Prolapsed Intervertebral Disc

Neurology lays many claims to being one of the more precise and scientific branches of medicine but, nevertheless, there have been several neurological conditions almost mediaeval in their conceptions. One of these is a group included under the general heading of the neuritides-namely, sciatic and brachial neuritis and neuralgia. There is now a large body of evidence to show that the humoral, a...

Degeneration of the intervertebral disc

The intervertebral disc is a cartilaginous structure that resembles articular cartilage in its biochemistry, but morphologically it is clearly different. It shows degenerative and ageing changes earlier than does any other connective tissue in the body. It is believed to be important clinically because there is an association of disc degeneration with back pain. Current treatments are predomina...

Methanolysis of the intervertebral disc.

Methanolysis of intervertebral disc samples at 600 was largely hydrolysis as shown by the absence of methylated derivatives on chromatograms of the reaction products. Extent of the reaction increased with acid strength; the products were the same. Maximum solubilization was about 80% and 50% for hyaline cartilage plate and nucleus pulposus samples, respectively. The results of aqueous acid (hyd...
