Anti-Inflammatory and Anti-Nociceptive Activities of Native and Modified Hen Egg White Lysozyme

Persistent inflammatory conditions can have severe pathological consequences. Although the use of nonsteroidal anti-inflammatory drugs (NSAIDs) is effective, it has side effects, particularly at the gastrointestinal level. There is then a high interest to identify natural anti-inflammatory compounds with no side effects. The anti-inflammatory and anti-nociceptive activities of hen egg lysozyme (LZ), both in its native form and modified by heat treatment, chemically or by enzymatic digestion have been tested in this study. The carrageenan-induced model in mice using native LZ or modified LZ has been applied. It was observed that LZ denatured by heat treatment at pH 6.0 presented 39.47% of inhibition of paw edema when administered at 30 mg/kg. LZ denatured with DL-dithiothreitol (DTT) presented a significant result of 42.10% inhibition of paw edema when administered at 30 mg/kg of animal weight. Modified LZ showed anti-inflammatory capacity comparable with the activity of the positive control dexamethasone. A classical model of acetic acid-induced abdominal writhing tests in mice was used to assess anti-nociceptive activity of native LZ and denatured heat treatment LZ and denatured chemical agent LZ. Finally, hydrolyzed native LZ presented 48% of inhibition of abdominal writhing in mice. Modified LZ with heat, chemical, and hydrolysis presented anti-inflammatory and anti-nociceptive activities independently of their natural enzymatic activity. These novel data point out the potential use of denatured and digested LZ as therapeutic agents and offer alternatives to the use of NSAIDs. LZ can be a natural source of anti-inflammatory and anti-nociceptive agents.

Antiulcerative and Antinociceptive Activities of Casein and Whey Proteins
Wilman Carrillo,Karin Maia Monteiro,Humberto Spindola,Mercedes Ramos,Joao Ernesto de Carvalho 한국식품영양과학회 2018 Journal of medicinal food Vol.21 No.6
The aim of this study was to evaluate the antiulcerative and antinociceptive activities of milk proteins using the induced gastric ulcer with ethanol rat model and the acetic acid-induced writhing mouse model. Casein (CN), (100, 300, and 1000 mg kg−1) doses presented antiulcerative activity on a dose-dependent manner with values of 30.8%, 41.4%, and 57.0% of inhibition measured using the ulcerative lesions index (ULI), respectively. Whey protein concentrate (WPC), (100, 300, and 1000 mg kg−1) doses presented antiulcerative activity on a dose-dependent manner with values of 48.9%, 65.5%, and 68.22% of ULI inhibition, respectively. CN, casein hydrolysates (CNH), WPC, and whey protein hydrolysates (WPH), (3, 10, and 30 mg kg−1) doses presented antinociceptive activity using the acetic acid-induced writhing in the mouse model. CN (30 mg kg−1) presented a value of 40% of inhibition writhing, and CNH (30 mg kg−1) presented antinociceptive activity with a value up to 46% of writhing inhibition. WPC (30 mg kg−1) presented a value of 52.50%, and WPH (30 mg kg−1) presented antinociceptive activity with a value up to 88.00% of writhing inhibition. In conclusion, CN and WPC demonstrated in vivo antiulcerative properties and represent a promising alternative to be used as protectors of the gastric mucosa. CNH and WPH demonstrated in vivo antiulcerative properties and represent a promising alternative to be used as natural analgesic.
