Background: Meloxicam is an NSAID of the oxicam class that acts by inhibiting prostaglandin synthesis and inducibleCOX-2, thereby exerting anti-inflammatory effect. This study aimed to evaluate the level of alkaline phosphetase andhigh sensitivity C - reactive protein as response to sulcular injection of meloxicom using a rabbit model.Material and method: Forty five male rabbits of the same species were divided into three groups. Group 1 whichincluded 20 rabbits that injected with meloxicon in a dose equal to the human therapeutic dose /kg .Group 2 whichincluded 15 rabbits that injected with normal saline. Group 3 which included 10 rabbits used as control group. Five mlof blood was collected from the rabbits ear vien for biochemical analysis at deferent time interval. Biochemicalanalysis included alkaline phosphetase (ALP) which analyzed by using Biolabo kit and High sensitivity C- reactiveprotein (hs- CRP) was measured using ELISA technique.Results: The result showed that the level of ALP after 1 day of sulcular injection in group 1 was 101.25 then it wasdecrease to 97.50 after 14 days while mean of ALP in group 2 was 70.33 After 1 day of injection and reach to 74.67After 14 days and this almost near to the mean value of control groupStatistic description of hs-CRP for group 1 was decreased. The mean value from 11.617 after 1 day to 3.639 after 14days. For group 2 also there was decreased in the mean from 11.556 after 1 day to 3.536 after 14 days, while for thecontrol group the mean value was 3.170 .Conclusions: The sulcular injection of NSAIDs seems to be of particular interest. This may help to further reduceadverse systemic effects of NSAIDs in treatment of periodontal disease safely.

Background: Maxillary sinusitis is one of the most common infections of humans. Sinusitis can be defined as an inflammation of the membrane lining of any sinus, especially one of the paranasal sinuses. Objective: To determine the causative microorganisms of chronic maxillary sinusitis. Patients: Forty five chronic sinusitis patients were involved in the present study. Methods: Sampling method were sinus specimens (aspiration or injection aspiration). Results: Haemophilus species, Streptococcus pneumoniae (S.pneumoniae) and Moraxella catarrhalis (M.catarrhalis) were the most frequent isolates; in addition Penicillium and Cladosporium species were isolated from some chronic sinusitis patients. Conclusion: Chronic sinusitis could be caused by either bacterial species or by fungal species; most bacterial isolates were Haemophilus species followed by S.pneumoniae and M.catarrhalis. The incidences of chronic sinusitis were more at patients age (20-29 years) old groups.

Flow injection chemiluminescence procedure is described for determination of some amino compounds, based on their reaction with bromine produced from reaction of bromate/bromide mixture in acidic medium. Some bromine is consumed and the rest catalyze the chemiluminescence intensity of luminol/H2O2 system. The flow injection chemiluminescence methods with merging zone principle were conducted instantly through an on-line design. Sampling rate was 95 s.h-1 . Amino compounds such as aniline, 1-naphthyl amine, o-anisidine, 2-methyl aniline and acryl amide were determined and best working conditions for their determinations were optimized. Linear calibrations of these compounds were in the range 1x10-7 – 1x10-2 M with correlation coefficients of (0.989), (0.985), (0.992), (0.997) and (0.980) respectively.

ABSTRACTAims The periodontal ligament injection in isolated areas of the mandible was clinically evaluated us-ing only a conventional dental cartridge syringe. Materials and Methods: One hundred subjects requir-ing extractions of either premolars or molars participated in the study. Results: A high percentage of success rate (85%) was achieved but with unfavorable comment from the patient in regard to a painful injection. Duration of surgical anesthesia following the injection proved to be adequate in almost all extractions performed. Conclusions: New devices for performing this injection appear to have some advantage over the conventional syringe technique. However, these devices were unfortunately unavail-able at the area of study. Further studies are recommended to further evaluate its success and also to determine the response of both the periodontal ligament and pulpal tissue in cases were restorative treatment of teeth is to be undertaken for example crowns, bridges and fillings

A simple and rapid flow injection (FI) spectrophotometric procedure for the determination of tetracycline (TC) has been developed. The method is based on the injection of 150 μl standard or sample solution into a distilled water carrier stream which merged at the merging zone with ferric nitrate solution with the optimum flow rate of 1.5 mL/min, subsequently the reaction will occur inside the reactor coil, forming brown color product that monitored at 418 nm. The flow injection experimental conditions were optimized by means of full factorial design. Under the optimum conditions, calibration graph was obtained over the range 2.0-120 μg/ml with a detection limit of 1.0 μg/ml. The correlation coefficient and molar absorptivity were 0.9994 and 4.343x103 L/mol.cm respectively. The results showed a good precision and accuracy. The method was successfully applied to the determination of tetracycline in pharmaceutical formulations and showed good agreement with those obtained by the standard method at 95% confidence level, with a sample throughput of 60/h.
