Background: The postoperative pain in children and adolescents is most commonly managed by intramuscular injections of NSAIDs or opioids. This approach may result in fluctuating plasma drug levels and cycles of pain, comfort, and sedation. Patient-controlled analgesia(PCA) is a method of analgesia administration that consists of a computer-driven pump with a button that the patient may press to administer a small dose of analgesic drug. Materials & Methods: Forty ASA physical status 1 or 2 children and adolescents were divided into two groups. In the PRN group, patients received intramuscularly diclofenac(Valentac$^{(R)}$) on a p.r.n. basis. The PCA group patients received a mixture of nalbuphine and ketorolac by WalkMed$^{(R)}$PCA infusor. Analgesic efficacy was evaluated with NRS(numerical rating scale) and Faces Pain Rating Scale. The side effects were evaluated. Results: The patients of PCA group had less pain than those of PRN group. Complications were similar in both group. Conclusions: PCA with nalbuphine and ketorolac is a safe and effective methods of pain relief in children and adolescents after surgery, and is better accepted than intramuscular injections.

Curcumin, a dietary pigment responsible for the yellow color of curry, has been used for the treatment of inflammatory diseases and exhibits a variety of pharmacological effects such as anti- inflammatory, anti-tumor, anti-oxidant, and anti-viral activity. In order to examine the potency of the curcumin in inflammation we used carrageenan induced rat hind paw odema model. As curcumin is practically water insoluble, it is hypothesized that pharmacological activity of curcumin could be improved by enhancing its water solubility. Water soluble complexes of curcumin with cyclodextrins were prepared and screened for greater solubility. Pure curcumin 100 mg/kg body weight along with curcumin complexes equivalent to 100 mg/kg body weight of pure curcumin were tested for the anti-inflammatory activity in Wister rats male rats using carrageenan induced hind paw edema model and compared with that of the reference compound diclofenac sodium at a dose level of 10 mg/kg body weight. Results were statistically analyzed using ANOVA. All the treatment groups showed statistically significant anti-inflammatory activity compared with that of vehicle control and positive control.

The ethanol extract of leaves of the mangrove Aegiceras corniculatum Blanco (Myrsinaceae) was screened for its antinociceptive, antidiarrhoeal and cytotoxic activities. The extract produced significant writhing inhibition in acetic acid-induced writhing in mice at the oral dose of 250 and 500 mg/kg body weight (P < 0.001), which was comparable to the standard drug diclofenac sodium at the dose of 25 mg/kg of body weight. When tested for its antidiarrhoeal effects on castor oil induced diarrhoea in mice, it increased mean latent period and decreased the frequency of defecation significantly at the oral dose of 500 mg/kg body weight (P<0.05; P<0.01) comparable to the standard drug loperamide at the dose of 50 mg/kg of body weight. Moreover, when tested for toxicity using brine shrimp, the extract showed potent activity against the brine shrimp Artemia salina ($LC_{50}$ 10 mg/ml). The overall results tend to suggest the antinociceptive, antidiarrhoeal and cytotoxic activities of the extract.

The crude methanol extract of the roots of Achyranthes aspera Linn. was investigated for its possible antinociceptive, diuretic and neuropharmacological activities in animal models. At the dose of 250 and 500 mg/kg body weight, the extract showed a significant antinociceptive effect in acetic acid induced-writhing in mice comparable to that produced by diclofenac sodium, used as standard drug. The crude extract produced significant diuretic effect at the dose of 500 mg/kg of body weight comparable to that produced by furosemide, used as standard drug. The extract also potentiated significantly the pentobarbital induced sleeping time in mice; decreased the open field score in open field test, decreased the number of hole crossed from one chamber in the hole cross test and decreased the head dip responses. The obtained results provide a support for the use of this plant in traditional medicine and its further investigation.

In the present investigation, we studied the effect of alcoholic extract of Moringa oleifera (M. oleifera) seed kernels on various experimental models of bronchial asthma. Significant (P < 0. 05) increase in preconvulsion time was observed due to pretreatment with M. oleifera when the guinea pigs were exposed to either acetylcholine (Ach) or histamine aerosol. This bronchodilating effect of M. oleifera was comparable to ketotifen fumarate. Spasmolytic effect of M. oleifera was also observed by dose dependent inhibition of ideal contractions induced by Ach, 5HT, histamine and $BaCl_2$. Alcoholic extract of M. oleifera produced significant dose dependent protection by egg albumin and compound 48/80 induced mast cell degranulation. Pretreatment with alcoholic extract of M. oleifera also decreased carrageenan induced rat paw edema, which was comparable to that of standard diclofenac sodium. Minimum inhibitory concentration for alcoholic extract of M. oleifera was low as compared to cold-water extract and hot water extract when antimicrobial activity was tested against various respiratory pathogens like Escherichia coli (E. coli), Staphylococus aureus (S. aureus) and pseudomonas aeruginosa (P. aeruginosa). Our data suggest that antiasthmatic activity of M. oleifera seed kernels may be due to its bronchodilator, anti-inflammatory, mast cell stabilization and antimicrobial activity.

The crude ethanol extract of the stem bark of Trewia polycarpa (Family: Euphorbiaceae) was subjected to acetic acid induced writhing inhibition, Brine Shrimp lethality bioassay and 1, 1-diphenyl-2-picryl hydrazyl free radical scavenging assay for screening of analgesic, cytotoxic and antioxidant activity respectively. The extract produced significant (P < 0.001) writhing inhibition in acetic acid induced writhing in mice at the dose of 125, 250 and 500 mg/kg body weight respectively, which were comparable to the standard drug diclofenac sodium. The extract showed significant lethality to Brine Shrimp and the $LC_{50}$ value was $8\;{\mu}g/ml$. The extract showed prominent free radical scavenging activity ($IC_{50}$ about ${\sim}10\;{\mu}g/ml$) compare to standard drug ascorbic acid ($IC_{50}about\;{\sim}15\;{\mu}g/ml$). The results tend to suggest that the crude ethanol extract of the bark might possess analgesic, cytotoxic and antioxidant activities or active constituent(s) responsible for the activities.

Purpose: There is a strong correlation between trauma and pain. Pain increases the rate of depression, posttraumatic stress disorder, and even mortality in trauma patients. Methods: This institution-based, provider-blinded and patient-blinded, observational study was conducted among trauma patients treated at Tikur Anbessa Specialized Hospital. Over the course of 3 months, this study included patients who had no prior pain management at other hospitals before presentation, and who presented within 24 hours of the traumatic event. Results: Of the 74 patients evaluated, none of the patients had their pain level scored. The researcher-provided pain scale showed a severe subjective pain score for 79.7% of the patients and a severe functional activity score for 59.5% of the patients. Analgesia was provided at an average of 55.4 minutes after presentation and all patients received either diclofenac or tramadol. Satisfactory pain reduction after analgesia was 28.8% for patients initially complaining of severe pain, 54.6% for moderate pain, and 66.7% for mild pain, with the difference being statistically significant (P<0.05). Forty percent of patients discharged home received no analgesia after the first dose provided upon presentation. Conclusions: Pain scoring was nonexistent during the course of the study. The poor utilization rate of analgesia combination and opioids led to unsatisfactory pain outcomes in patients evaluated and followed for 24 hours after presentation.

In the present study, the anti-inflammatory effect of Jungcheonhwadamgangki-tang plus antler water extract was tested in formalin-injected chronic inflammation model in mouse hind paw. The test articles were dosed once a day for 10 days, and changes on the body weight, paw weights were observed with histopathology of induced paw dorsum pedis. In addition, histomorphometry was also monitored at sacrifice. 15 mg/kg/10 mL of dexamethasone (DEXA) and diclofenac (DICLO) intraperitoneally dosed groups were used as reference groups. A significantly decrease of both absolute and relative paw weights were observed in all dosing groups including DEXA and DICLO groups compared to that of control, and a significantly decrease of the differences between intact and induced paw weights were also observed Jungcheonhwadamgangki-tang plus antler dosing groups compared to that of control. These histological signs-hypertrophy of paw dorsum pedis tissues were detected results from edematous changes on the cutaneous and subcutaneous tissues with severe infiltration of chronic inflammatory cells-were dramatically decreased in all dosing groups including DEXA and DICLO dosing groups compared to that of control. Especially, dose dependently decreases were detected in Jungcheonhwadamgangki-tang plus antler dosing groups compared to that of control. Base on these aforementioned results, it is concluded that Jungcheonhwadam- gangki-tang plus antler have clear anti-inflammatory effect on the chronic inflammation induced by formalin injection.

Objectives : To investigate the utilization patterns of non-steroidal anti-inflammatory drugs (NSAIDs) among the elderly with osteoarthritis (OA) undergoing primary ambulatory care in Busan metropolitan city, Korea. Methods : OA patients, aged 65 years and over, were identified from the Korean National Health Insurance Review Agency drug prescription database. The subjects had at least one episode of claim for OA (ICD-10-CM: M15-M19) between August 1, 2000 and February 28, 2002. Trends in the determinations of NSAIDs utilization were identified using chi-squared tests for trend. Results : There were 47,711 osteoarthritic patients. The total number of visits by these patients was 177,443, with a total frequency for NSAID prescriptions of 214,952. Seventy-nine percent of the OA patients were female. NSAIDs were prescribed on 133,284 visits (75.1%) and the proportion of prescriptions was significantly increased with age. Only the proportion of visit when NSAIDs were prescribed decreased, from 65.1 to 43.5%, during the study period (p<0.001). However, the proportion of combined treatments with anti-ulcer drugs was increased. The use of NSAIDs injections was decreased. Of the individual NSAIDs, diclofenac (28.7% of total frequency of NSAID prescriptions), piroxicam (15.0%) and talniflumate (8.7%), were the most frequently prescribed. Among the NSAIDs prescribed OA visits, 45.7% used two or more NSAIDs. Conclusion : The total proportion of NSAIDs prescribed to the osteoarthritic patients was higher than in other studies. The decline in the use of NSAIDs during the study period, and the frequent selection of safer medications, such as combination therapy with anti-ulcer drug, may reflect the risk awareness of the use of NSAIDs.
