chymopapain/inflammation

Chymopapain degrades the nucleus pulposus portion of the intervertebral disk of rabbits. The degradation is not grossly visible until 15 days post-injection. Depolymerization of the chondromucoprotein and decreases in the ability of a disk to imbibe fluid, is, in effect, a "chemical decompression"

Ninety of 120 patients with herniated lumbar discs who received an intradiscal injection of chymopapain achieved successful recovery. Sixteen of the 21 patients who underwent subsequent surgery had a good result. Study of the unsuccessful cases showed that disc sequestration and lateral stenosis

A new model employing latex of papaya as an inflammagen has been developed for testing anti-inflammatory activity. The latex (exudate) was harvested from the unripe papaya fruit, which had been dried under vacuum. The latex was then suspended in 0.05 M sodium acetate buffer. This suspension when

Subarachnoid hemorrhage is a frequent finding in patients who have incurred neurological complications following chymopapain chemonucleolysis, but the basis for this occurrence remains controversial. The authors report the clinical and postmortem findings in a 42-year-old man who died 5 days after

Epidural adhesions were discovered in seven of nine patients undergoing surgery for failed chymopapain chemonucleolysis. Clinically the adhesions were very vascular, prolific and adherent to the nerve root, dura and the porieties. The histological composition was similar to the normal tissues of the

Immediate and long-term microvascular effects of chondroitinase ABC, 200 unit/ml, were analyzed in ten hamsters. The immediate effects on the microcirculation were studied by vital microscopy following local injection in the cheek pouch. There were no detectable effects on the microvascular blood

The mechanism of action underlying chymopapain (Chymodiactin) chemonucleolysis remains obscure. Radiographic studies suggest that chymopapain does not alter disc fragment size acutely; nonetheless, patients often report symptom resolution within a few days, even hours, of treatment. The authors

The symptom of back pain may be the result of many different pathologies. As such, patients with back pain require careful assessment to determine whether the cause is from the spine or other systems. For acute mechanical back pain, treatment is often symptomatic. Symptomatic treatment may include

Low back pain is the most common cause of disability under the age of 45. The annual incidence of back pain is estimated to be 5% and the lifetime prevalence is 80%. Majority of the patients with persistent symptoms are suffering from radiculopathy that is mainly caused by a herniated nucleus

OBJECTIVE To develop a method to correct for the unknown dilution of synovial fluid that occurs during lavage of a joint, we evaluated the utility of urea, a molecule that is neither synthesized nor metabolized by joint tissues, as a means of correcting for the dilutional effects of lavage

Detailed studies of the biochemistry and pharmacology of mast cell-mediated inflammatory disorders have been hampered by the inability to purify human mast cells. We now report techniques to purify human lung mast cells to apparent homogeneity. The major purification steps are: 1) dispersion of lung

OBJECTIVE To evaluate the effects of orally administered glucosamine hydrochloride (GlAm)-chondroitin sulfate (CS) and GlAm-CS-S-adenosyl-L-methionine (SAMe) on chemically induced synovitis in the radiocarpal joint of dogs. METHODS 32 adult mixed-breed dogs. METHODS For 21 days, all dogs received a

OBJECTIVE To determine whether the basic science evidence supports the use of continuous passive motion (CPM) after articular cartilage injury in the knee. METHODS A systematic review was performed identifying and evaluating studies in animal models that focused on the basic science of CPM of the

In patients with low back pain (LBP) it is only possible to diagnose a small proportion, (approximately 20%), on a patho-anatomical basis. Therefore, the identification of relevant LBP subgroups, preferably on a patho-anatomical basis, is strongly needed. Signal changes on MRI in the vertebral body
