Abstract Background Honey bee venom contains various enzymes with wide medical and pharmaceutical applications. Results The phospholipase A2 (PLA2) has been apparently purified from the venom of Egyptian honey bee (Apis mellifera lamarckii) 8.9-fold to a very high specific activity of 6033 U/mg protein using DEAE–cellulose and Sephacryl S-300 columns. The purified bee venom PLA2 is monomeric 16 kDa protein and has isoelectric point (pI) of 5.9. The optimal activity of bee venom PLA2 was attained at pH 8 and 45 °C. Cu2+, Ni2+, Fe2+, Ca2+, and Co2+ exhibited a complete activating effect on it, while Zn2+, Mn2+, NaN3, PMSF, N-Methylmaleimide, and EDTA have inhibitory effect. Conclusions The purified bee venom PLA2 exhibited anti-platelet aggregation and anti-coagulation activities which makes it promising agent for developing novel anti-clot formation drugs in future.

Honeybees are one of the most marvelous and economically beneficial insects. As pollinators, they play a vital role in every aspect of the ecosystem. Beehive products have been used for thousands of years in many cultures for the treatment of various diseases. Their healing properties have been documented in many religious texts like the Noble Quran and the Holy Bible. Honey, bee venom, propolis, pollen and royal jelly all demonstrated a richness in their bioactive compounds which make them effective against a variety of bacterial strains. Furthermore, many studies showed that honey and bee venom work as powerful antibacterial agents against a wide range of bacteria including life-threatening bacteria. Several reports documented the biological activities of honeybee products but none of them emphasized on the antibacterial activity of all beehive products. Therefore, this review aims to highlight the antibacterial activity of honey, bee venom, propolis, pollen and royal jelly, that are produced by honeybees.

ABSTRACTHoney Bee Venom has various biological activities such as inhibitory effect on several types of cancer. Cisplatin is an old and potent drug to treat the most of cancer. Our aims in this study were determination of the anti-mutagenic and cytotoxic effects of HBV on mammary carcinoma, lonely and in combination with cisplatin. In this study 4T1 cell line were cultured and incubated at 37 C in humidified CO2-incubator. The cell viabilities were examined by MTT assay. Also HBV was screened for its anti-mutagenic activity against sodium azide by Ames test. The result showed that 6μg/ml HBV, 20μg/ml cisplatin and 6μg/ml HBV with 10μg/ml cisplatin can induce an approximately 50% 4T1 cell death. 7mg/ml HBV with the inhibition of 62.76% sodium azide showed high potential in decreasing the mutagenic agents. MTT assay demonstrated that HBV and cisplatin can cause cell death in a dose-dependent manner. The cytotoxic effect of cisplatin is also promoted by HBV. Ames test results indicated that HBV can inhibit sodium azide as a mutagenic agent. Anti-mutagenic activity of HBV was increased significantly in presence of S9 mix. Hence, our findings reveal that HBV can enhance the cytotoxic effect of cisplatin drug and it has cancer preventing effects.

Introduction Glucocorticosteroid injections have been widely used in clinical practice. Betamethasone is one of the agents of this group of drugs. Its efficacy and therapeutic effect with intra-articular administration are undeniable. There are special instructions on the dosage and frequency of use of the drug but unfortunately there are cases of its wrong administration. There is also an evidence of an adverse effect on cartilage both of the drug itself and its combination with local anesthetics. Aim Evaluation of the results of different weekly intra-articular protocols of betamethasone administration on histological preparations of rabbit knee joints. Methods Histological preparations of the right knee joints of three groups of rabbits were studied: after one, three, and six administrations of betamethason per week and the control intact left knee joints. Results Histological preparations of the control group and the group with a single weekly administration of the drug did not have any changes in the structure of diarthrosis. Dystrophic and necrotic changes affecting all morphological components were observed in the joints of animals that received intra-articular injections of betamethason three times a week (compared to a single injection, the area of dystrophy and necrosis of the cartilage was greater by 10.05 ± 0.75 % (p < 0.05), of subchondral bone by 8.11 ± 0.5 % (p < 0.001), and of synovium by 6.25 ± 0.32 % (p < 0.05). The group with six injections of the drug per week had the most pronounced changes. The area of necrotic changes of the cartilage was greater by 6.39 ± 0.75 % than in the group with three injections per week (p < 0.001), of subchondral bone by 11.18 ± 0.5 % (p < 0.001), of synovium by 6.12 ± 0.32 % (p < 0.001). Discussion Inflammatory cell infiltration of joint structures was absent in all cases. It indicates an aseptic nature of tissue necrosis. Evidence has been obtained between the increase in the frequency of intra-articular injections of betamethasone and the severity of dystrophic and necrotic changes in all morphological components of the joint.
