Indoleacetic acid at 0.017 millimolar inhibited the formation of three peroxidase isoenzymes in both soluble and wall-bound enzyme fractions of wheat coleoptile (Triticum vulgare) tissue. Hydroxyproline at 1 millimolar prevented the indoleacetic acid-induced inhibition. Indoleacetic acid oxidase activity in the soluble fraction was decreased by indoleacetic acid and was restored by hydroxyproli...

Plant cell walls contain a glycoprotein rich in hydroxyproline. To determine how Acer pseudoplatanus L. cells transport this glycoprotein to the wall, the pulse-chase technique was used to follow changes in specific radio-activity of hydroxyproline and proline in isolated, mitochondrial, Golgi, microsomal, soluble protein, and wall fractions. The turnover rates or changes in specific radioactiv...

Oral supplementation with collagen hydrolysate (CH) has been shown to improve the condition of the skin in humans and experimental animals. Several hydroxyproline-containing oligo-peptides were previously detected in human peripheral blood after the ingestion of CH, and the two dipeptides, prolyl-hydroxyproline (PO) and hydroxyprolyl-glycine (OG), have been proposed to have beneficial effects o...

BACKGROUND Intra-articular adhesion is the commonest complication that is faced by orthopedic surgeons after knee surgery. Thus, the present investigation evaluates the effect of daidzein on intra-articular adhesion in rabbits. MATERIAL AND METHODS All the rabbits were separated in to four different groups each group carries ten rabbits. Cancellous bone was exposed in each rabbit by removing ...

The present study was performed to substantiate the traditional claim of the wound healing activity of stem bark of Albizzia lebbeck Linn. in rats. The effects of aqueous and ethanolic extracts of stem bark of A. lebbeck (5% and 10% w/v topically and 250 mg/kg and 500 mg/kg p.o.) on excision, incision and dead space wound model were examined. The extracts were administered orally for 10 days fo...

ETHNOPHARMACOLOGICAL RELEVANCE Carica papaya is traditionally used to treat various skin disorders, including wounds. It is widely used in developing countries as an effective and readily available treatment of various wounds, particularly burns. THE AIM OF THE STUDY This study was aimed at investigating the healing efficiency of papaya latex formulated as 1.0 and 2.5% hydrogels. MATERIALS ...

Delonix elata L. is a Ceasalpinaceae species and is traditionally used in India for treatment of skin diseases, liver diseases and rheumatic problems. However, systematic evaluation of its wound healing activity is lacking. Thus, in the present study, we aimed to assess the wound healing activity of D. elata stem bark extract (DSE) and its isolated constituent quercetin-3-rhamnopyranosyl-(1-6) ...

Amiodarone (AM) is an efficacious antidysrhythmic agent that can cause numerous adverse effects, including potentially life-threatening pulmonary fibrosis. The current study was undertaken to investigate potential protective mechanisms of vitamin E against AM-induced pulmonary toxicity (AIPT) in the hamster. Three weeks after intratracheal administration of AM (1.83 micromol), increased pulmona...

Determination of the 4-hydroxy-l-proline (hydroxyproline) concentration may provide useful information for the diagnosis and prognosis of diseases caused by disorders of collagen metabolism. The objective of the present study was to apply liquid chromatography-mass spectrometry (LC-MS) to assess the hydroxyproline concentration. The hydroxyproline concentration in lung and liver tissues measure...

effects of excess concentrations of boron on major cell wall components of tobacco cells(nicotiana tabacum l. cv. burley 21) were studied. pectin, xyloglucan, hydroxyproline-richglycoproteins (extensin), and arabinogalactan proteins were characterized. results showedthat increased boron supply resulted in significant decrease in cell and cell wall dry weights.also, high concentrations of boron ...
