Abstract
Pain is a symptom of disease and most diseases accompanied with pain, specially among hospitalized post-operative patients. Several drugs and routes of administrations have used for post operative pain control. We compared post op analgesic effects of Diclofenac suppository to intramuscular Pethedine in post op inguinal herniorrhaphy patients. This study is a clinical trial on 40 patients who were operated due to unilateral inguinal herniorrhaphy. They divided into two groups incidentally. In Diclofenac Na group each patient received 100 mg Diclofenac Na supp every 8 hours. In Pethedine group each patient received 0.5 mg/kg Pethedine, intramuscularly. Pain severity of the patients controlled for 24 hours with visual comparation method and mean pain severity compared among 2 groups in the first 24 hours. Mean pain severity difference of Pethedine groups patients compared to Diclofenac Na group was 6.10 with standard error of 3.57 with (P<0.212) had no meaningful difference during first post operative phase. We concluded that Diclofenac Na is a suitable substitute of 24 hours intramuscular Pethedine for post op pain relief.

Abstract
Background&Objective: Pain, in particular post-operative pains, can produce numerous complications including a delay in healing of wounds in patients. For pain relief in patients postoperatively, different drugs are used, opioids like pethidine and NSAIDs. This study was carried out to compare the effects of the IM pethidine and suppository Diclofenac for pain relief after laminectomy following lumbar disc hernia.
Materials&Methods: this is a randomized control clinical trial study, 100 patients presenting for laminectomy with diagnosis of lumbar disc hernia and eligible for participation in the study, after recieving their informed consent for inclusion in the study non probability convenience sampling were selected by a convenience sampling method and then divided into two groups of Pethidine (P) and Diclofenac (D). Patients’ pain scores were measured by Visual Analogue Scale (VAS). Finally, the data obtained were analyzed by statistical software of SPSS.10, F test, T test and ?² P<0.05 was considered significant.
Results: Mean pain scores within 24 hours after operation were calculated in group P as 2.8±2.02 and in group D as 4.46±2.30. There was a statistically significant difference between the reduction of the pain score after surgery in both groups (p<0.05). Nausea was the greatest side effect observed in group P (23%) and epigastric pain was the most common pain found in group D (18%). However, no statistically significant difference was found between the two groups in terms of the drug adverse effects.
Conclusion: A statistically significant difference was observed between pethidine ampule and Diclofenac suppository regarding the pain reduction after laminectomy. In the other words, Diclofenac suppository has less impact on pain killing in comparision with Pethidine ampule. In other to confirm these results, it is suggested that another study in terms of age and sex and after orthopedical procedures in a large scale-and if possible double blind- to be carried out.

Abstract
Background & Objective: Diclofenac is a non-steroidal, anti-inflamatory drug that is prescribed as an analgesic. However, there is little known about the effects of diclofenac on the neural cells. In this study, we investigated the effects of diclofenac as sodium salt on the proliferation and differentiation of PC12 cells.
Materials & Methods: This expeimental study was done in Kerman neuroscience research center during 2004. The cell proliferation was evaluated by using XTT assay in the both free-serum neurobasal medium supplemented with B27 supplement and DMEM/F12 medium containing 10% FBS. The nerve growth factor(NGF) – induced differentiation was assessed by measuring the neurite length for each treatment.
Results: The drug toxicity was exhibited at the higher concentrations of 310 mM in the supplemented neurobasal medium. The treatment of cells in the DMEM/F12 medium increased their sensitivity to diclofenac, with 40 and 85% growth inhibition at the 155 and 310 mM concentrations, respectively. The different generics of drug exhibited a equal toxic effects on the PC12 cells. The NGF- induced differentiation was not reduced by toxic and subtoxic concentrations of diclofenac.
Conclusion: This study indicated that diclofenac may be able to exhibit its neurotoxic effects through growth inhibition, but not differentiation inhibition. B27 supplement has several antioxidant compounds. Therefore, the difference of diclofenac cytotoxic effects in two culture media suggest that drug cytotoxicity may be related to the oxidative stress.

Abstract
Background and Objective: Chronic myeloid leukemia is one of the most well-known types of leukemia. Inflammation is one of the leading causes of cancer; therefore, anti-inflammatory agents are used for reducing and suppressing the growth of cancer cells. Dexamethasone, a cortisol agonist, has anti-inflammatory, anti-tumor, and apoptotic effects. Diclofenac is a cyclooxygenase enzyme inhibitor with anti-inflammatory properties. This study was performed to determine the synergistic effect of diclofenac and dexamethasone on the growth of K562 cancer cells.
Methods: In this descriptive-analytical study, K562 cell line was cultured in RPMI-1640 medium enriched with glutamine, penicillin, and streptomycin. The cytotoxic effects of dexamethasone, diclofenac and their combination (multi-target tracking) were evaluated using MTT assay. Hoechst staining and DNA electrophoresis were carried out to evaluate the occurrence of apoptosis.
Results: Diclofenac, dexamethasone and their combination had cytotoxic effects on the cells at concentrations of 20, 40, 60, and 80 µmol/ml. A significant cytotoxic effect was observed after 72 hours of treatment with different concentrations of the drugs (P<0.05). Hoechst staining showed that DNA fragmentation was increased in the treated cells. DNA electrophoresis also showed induction of apoptosis by diclofenac, dexamethasone, and their combination.
Conclusion: The combination of diclofenac and dexamethasone at concentration of 20 µmol/ml is more effective in inducing apoptosis in K562 cells compared with each drug alone.
