BACKGROUND: Propofol can produce a dose-dependent reduction in blood pressure by providing titratable sedation and rapid recovery. It has been reported that a combination of midazolam and propofol resulted in the significant reduction in the total dose of propofol needed. It was hypothesized that the addition of low-dose midazolam to propofol may provide sufficient sedation without compromising the hemodynamic stability. METHODS: A total of 40 consecutive patients were randomly assigned to one of two groups (n = 20 each). Group M-P received a bolus of 0.02 mg/kg of midazolam, followed by a propofol infusion with a fixed target concentration of 1.0microgram/ml. Group P received only a propofol infusion with an initial target plasma concentration of 2.5microgram/ml. Subsequent titration of the infusion rates in Group P or the additional midazolam boluses in Group M-P were made in order to maintain a predetermined sedation level. RESULTS: In Group P, a mean dose of 5.4 +/- 0.7 mg/kg/h propofol was used compared with 2.7 +/- 0.5 mg/kg/h in Group M-P (P<0.0001, plus additional 2.96 +/- 1.8 mg of midazolam). Ephedrine was administered to 15 patients in Group M-P and 17 patients in Group P. Recovery was significantly fast (Group P, 6.8 +/- 2.9 min vs. Group M-P, 9.8 +/- 4.4 min, P<0.05). CONCLUSIONS: Sedation with propofol plus midazolam requires a lower total dose of propofol compared with propofol alone but has no superior hemodynamic stability. A further study using younger patients and combinations of different doses of each drug will be needed.

Foeniculum vulgare Mill. (fennel) is used to flavor food, in cosmetics, as an antioxidant, and to treat microbial, diabetic and common inflammation. No study to date, however, has assessed the anti-inflammatory effects of fennel in experimental models of inflammation. The aims of this study were to investigate the anti-inflammatory effects of fennel in model of lipopolysaccharide (LPS)-induced acute lung injury. Mice were randomly assigned to seven groups (n=7~10). In five groups, the mice were intraperitoneally injected with 1% Tween 80-saline (vehicle), fennel (125, 250, 500micro l/kg), or dexamethasone (1 mg/kg), followed 1 h later by intratracheal instillation of LPS (1.5 mg/kg). In two groups, the mice were intraperitoneally injected with vehicle or fennel (250microl/kg), followed 1 h later by intratracheal instillation of sterile saline. Mice were sacrificed 4 h later, and bronchoalveolar lavage fluid (BALF) and lung tissues were obtained. Fennel significantly and dose-dependently reduced LDH activity and immune cell numbers in LPS treated mice. In addition fennel effectively suppressed the LPS-induced increases in the production of the inflammatory cytokines interleukin-6 and tumor necrosis factor-alpha, with 500microl/kg fennel showing maximal reduction. Fennel also significantly and dose-dependently reduced the activity of the proinflammatory mediator matrix metalloproteinase 9 and the immune modulator nitric oxide (NO). Assessments of the involvement of the MAPK signaling pathway showed that fennel significantly decreased the LPS-induced phosphorylation of ERK. Fennel effectively blocked the inflammatory processes induced by LPS, by regulating pro-inflammatory cytokine production, transcription factors, and NO.

PURPOSE: It is well known that expressive language impairment is commonly less severe than receptive language impairment in children with autism spectrum disorder (ASD). However, this result is based on experiments in Western countries with Western language scales. This study tries to find whether the result above is applicable for toddlers in a non-Western country; more specifically, in Korea with non-Western language scales. MATERIALS AND METHODS: The participants were 166 toddlers aged between 20 months and 50 months who visited the clinic from December 2010 to January 2013. The number of toddlers diagnosed as ASD and developmental language delay (DLD) was 103 and 63, respectively. Language development level was assessed using Sequenced Language Scale for Infants (SELSI), a Korean language scale. Using SELSI, each group was divided into 3 sub-groups. Moreover, the group difference by age was observed by dividing them into three age groups. Chi-square test and linear-by-linear association was used for analysis. RESULTS: Receptive language ability of the DLD group was superior to that of the ASD group in all age groups. However, expressive language ability in both groups showed no difference in all age groups. A greater proportion of expressive dominant type was found in ASD. The 20-29 months group in ASD showed the largest proportion of expressive language dominant type in the three age groups, suggesting that the younger the ASD toddler is, the more severe the receptive language impairment is. CONCLUSION: These findings suggest that receptive-expressive language characteristics in ASD at earlier age could be useful in the early detection of ASD.
