One of the most widely used techniques for water content determination in food is Karl Fischer (KF) titration. Compared to other methods based on loss of weight, the primary advantage of the Karl Fischer titration method is its high selectivity to water. The aim of the study was to develop and validate the Karl Fischer method for moisture determination in pollen loads, royal jelly, bee venom an...

Bee venom from honey bees (Apis Mellifera L.) is known to have many pharmacological and biological properties. Melittin, a peptide consisting of 26 amino acids, as the main component bee venom. The study aims develop rapid capillary electrophoresis method for separating quantifying melittin in honeybee Since basic peptide, it will adhere wall during separation. Two different methods were develo...

D-Tubocurarine (curare) and acetylcholine (ACh) had been found to block electrical activity after treatment of squid giant axons with cottonmouth moccasin venom at a concentration which had no effect on conduction. It has now been demonstrated that this effect is attributable to reduction of permeability barriers. The penetration of externally applied C(14)-labeled dimethylcurare, ACh, choline,...

Controversial immunomodulatory properties of bee venom (BV) have provided an appropriate field for more investigation. The aim of present research was to verify the effects of honeybee venom on matrix metalloproteinase activity and interferon production as well as cell proliferation in monocyte and fibroblast cell lines.The monocyte and fibroblast cell lines (K562, HT-1080, WEHI-164) were used ...

BACKGROUND Systemic reactions (SR) to venom immunotherapy (VIT) are rare but may occur, with a rate significantly higher for honeybee than for vespid VIT. In patients with repeated SRs to VIT it is difficult to reach the maintenance dose of venom and pre-treatment with omalizumab is indicated, as shown by some studies reporting its preventative capacity, when antihistamines and corticosteroids ...

INTRODUCTION Beekeepers are a group of people with high exposure to honeybee stings and with a very high risk of allergy to bee venom. Therefore, they are a proper population to study the correlations between clinical symptoms and results of diagnostic tests. AIM The primary aim of our study was to assess the correlations between total IgE, venom- and phospholipase A2-specific IgE and clinica...

Honey bee venom is a complex mixture of toxic proteins and peptides. In the present study we tried to extend our knowledge of the venom composition using two different approaches. First, worker venom was analysed by liquid chromatography-mass spectrometry and this revealed the antimicrobial peptide apidaecin for the first time in such samples. Its expression in the venom gland was confirmed by ...

Bee venom is a complex substance which acts in different ways; local or systemic anaphylaxis associated with IgE and direct toxic effects of the large volume of injected venom. We report a 10- year-old boy who was the vulnerable of 5989 honey bee attacks. To the best of our knowledge, this case had the ultimate number of honey bee stings in the literature, until now. He was admitted to pediatri...

Subcutaneous injection of bee venom causes long-term neural activation and hypersensitization in the dorsal horn of the spinal cord, which contributes to the development and maintenance of various pain-related behaviors. The unique behavioral 'phenotypes' of nociception and hypersensitivity identified in the rodent bee venom test are believed to reflect a complex pathological state of inflammat...
