Spices are any pungent, aromatic plant substances used to flavor food or beverages. Plant foods and agricultural commodities including spices are increasingly subjected to adulteration by design or default. This study aimed to compare home grinded spices against ready locally prepared ones in Libyan market. Chosen spices were compared according to their percentage of yield, organoleptic features, and pharmacognostic parameters as macroscopic and microscopic characteristics, pH measurement, microbial contamination (total viable count and microbial identification), and thin layer chromatography (TLC) chromatogram and diphenyl picryl hydrazyl (DPPH) scavenging activity. From the results, the ready prepared samples showed to have higher percentage of yield compared to home prepared ones. There were no difference in organoleptic test results, macroscopic and microscopic characteristics and pH test results. Bacteria in spices samples were too many to count (TMTC) in most samples, however thyme, rosemary and cinnamon showed better results. The isolated bacteria were identified as Salmonella, Shigella and E. coli species. TLC chromatogram and DPPH scavenging activity test also showed no difference in both sample groups. All these tests indicates that the samples obtained from market as grinded powder and the same samples of spices that was brought as a raw materials and grinded at home had the same characteristics, which indicated that they are of the same quality which not necessary to be a good one. arabic 12 English 75

Paracetamol is one of the most widely used drug as antipyretic and analgesic for mild to moderate pain. Currently, paracetamol is the first-line choice for pain management and antipyresis. Ion channels are pore-forming proteins that allow the flow of ions across membranes and involved in many cellular processes; drugs acting on ion channels have long been used for the treatment of many diseases. Objective: To estimate the effect of voltage gated ion channel blockers on analgesic activity of Paracetamol and explore the interaction between ion channel blockers and paracetamol on pain behaviour. Materials and Methods: Male albino mice were used. The central antinociceptive activity was determined by hot plate test and formalin test (Phase I; neuropathic pain). Antiinflammatory activity was determined by formalin test (Phase II). Intraperitoneal injection was adopted. Five groups of mice were used. Group 1; control group (1% T80), group 2; treated with (200mg/kg) paracetamol, group 3; treated with different drugs of ion channel blockers, group 4; received standard drugs, Aspirin (200mg/kg) for formalin test (phase II) or tramadol (5mg/kg) for hot plate test and formalin test (phase I), group 5; received combined treatment of ion channel blockers and paracetamol. Results: Pain produced by noxious stimuli (heat and formalin) was significantly reduced by acute administration of paracetamol. Inflammation pain produced by formalin injection was significantly decreased by acute administration of paracetamol. Acute administration of nifedipine showed significant decrease in nociception and inflammation pain. Combined treatment of nifedipine and paracetamol produced antinociceptive and anti-inflammatory activity but less than the additive effect. Verapamil has no analgesic effect in the two models, and did not change the affect of paracetamol analgesic activity when administered together. Phenytoin produces significant decrease in nociceptive pain using hot plate but not in formalin test (Phase I), and produce significant decrease in inflammatory pain (Phase II). The combined treatment of phenytoin and paracetamol showed analgesic activity less than the additive effect. 4-Aminopyridine produces significant antinociceptive and anti-inflammatory activity. The combined administration of 4-aminopyridine and paracetamol showed analgesic activity, which is less than the additive effect using formalin test, while paracetamol analgesic activity is potentiated by 4-aminopyridine using hot plate test. Conclusion: Paracetamol has antinociception and anti-inflammatory activity on pain model used (Hot plate test and Formalin test). Ion channel blockers produce antinociception and anti-inflammatory activity. Verapamil has no effect on nociception or inflammation pain and no effect on paracetamol analgesic activity. Nifedipine, phenytoin and 4-aminopyridine interact with paracetamol producing less additive analgesic effect, except 4-aminopyridine in thermal stimuli (Hot plate) is more sensitive compared to chemical stimuli (formalin test – phase I), where potentiates paracetamol action.

Aims: Diabetic foot ulcer is a significant complication of diabetes mellitus and often proceed lower extremely amputation. Propolis is a naturally occurring anti-inflammatory bee derived protectant resin. Previously, topically applied propolis has been reported to reduce inflammation and improves cutaneous ulcer healing in diabetic rodents. This study aimed to determine the Libyan honey and propolis activity and honey against bacteria isolated from diabetic foot ulcer lesion Study Design: In vitro antimicrobial activities of honey and crude hexane and methanolic extract of Libyan propolis against bacteria isolated from diabetic foot ulcer lesion Place and Duration of Study: Samples collected from patient in Tripoli Iben Nafees Hospital using disc and agar diffusion method. Methodology: Disk diffusion method on groups of aerobic and anaerobic bacteria were obtained from diabetic foot lesion. Results: The result showed that the percentage of aerobic bacteria isolated from diabetic lesion was about 74%, which include MRSA, E. coli, Ps. aeruginose, Citrobacter, Pantoea, Proteus, Staphylococcus epidermis, Enterobacter and Serratia bacteria. Whereas anaerobic bacteria reported about 26% of Clostridium, Bacteroides, and Lactobacillus Jensenii. Conclusion: It was concluded that the honey and propolis extract had antibacterial activity against a different type of aerobic and anaerobic bacteria that were isolated from diabetic foot ulcer lesion.
