Bacterial enzyme ‘Hyaluronidase’ is a complex polysaccharide degrading enzyme that cleaves â-GlcNAc-(14) glycosidic linkage of Hyaluronate (HA) by â-elimination process. It is synthesized by a spectrum of grampositive bacteria which serve as potential contributors to a multitude of infectious diseases in human beings. Especially, group A streptococcus bacteria (GAS) have evolved several orders...

(1) The spreading reaction is a biological method, measuring the decomposing effect of hyaluronidase on the mucoids of the cement substance of rabbit's skin (Duran-Reynals, 1929). These substances consist partly of hyaluronic acid. Hyaluronidase increases the permeability of the tissues, and this involves an increased spreading capacity of liquids and corpuscular substances. This test is not sp...

BACKGROUND Oral submucous fibrosis (OSMF) is a chronic debilitating and potentially malignant condition of the oral cavity. It is resistant and progressive affecting the entire oral cavity that sometimes causes a gradual reduction in mouth opening that may even extend up to the pharynx. Although the medical treatment is not completely systematized, optimal doses of its treatment with local inje...

Background: Oral submucous fibrosis (OSMF) is a common premalignant condition caused by chewing arecanut, betel quid and gutkha with tobacco. Its medical treatment is not yet fully standardized, although the optimal doses of its medical treatment is in the form of triamcinolone acetonide combined with hyaluronidase or intralesional placental extract. Objectives: We compared the efficacy of intr...

The increase in the frequency and popularity of aesthetic filler injections is accompanied by a high risk complications, including ophthalmological sequalae. Of these, loss vision considered most dangerous and, cases, irreversible. We present case report patient who experienced acute due to suspected partial occlusion ophthalmic artery following nonsurgical rhinoplasty with hyaluronic acid inje...

The aim of this study was to determine the effects of progesterone and testosterone hormones on the hyaluronidase activities of serum and semen and on sperm characteristics in sheep. Thirty healthy Akkaraman sheep were used. The progesterone and testosterone were injected intramuscularly at the rate of 0.5 mg/kg and 5 mg/kg, respectively. Then the blood and semen samples were obtained from the ...

Facial fillers are becoming increasingly popular as aesthetic procedures to temporarily reduce the depth of wrinkles or to contour faces. However, even in the hands of very experienced injectors, there is always a small possibility of vascular complications like intra-arterial injection of filler substance. We present a case report of a patient who developed features of vascular obstruction in ...

BACKGROUND & OBJECTIVES Oral submucous fibrosis is a common premalignant condition caused by chewing arecanut and other irritants in various forms. Its medical treatment is not yet fully standardized, although the optimal doses of its medical treatment is in the form of hydrocortisone acetate combined with hyaluronidase. The problem with the prevailing treatment was injections at weekly interva...

OBJECTIVE To evaluate the effect of hyaluronidase in patients with failed back surgery syndrome (FBSS) treated with interlaminar lumbar epidural injection (ILEI). METHOD Sixty patients suffering from severe low back pain and sciatica were randomly allocated into three groups. Group T received ILEI with 2 ml triamcinolone 40 mg/ml and 5 ml bupivacaine 0.25%. Group H received ILEI with 1500 IU ...
