A field trial on the control effect of fipronil poison bait against German cockroaches (Blatella germanica) was carried out at different restaurant types in Sinchon, Seoul, Republic of Korea. Monitoring was performed applying food baited traps for 2 days per week. Reduction rates of German cockroaches by applying fipronil baits were 90.9% at Korean restaurants, 96.4% at Chinese restaurants, and 89.4% in beer hall kitchens after 4 weeks of the treatment. Overall average of the reduction rate was 93.9%. As the natural reduction rate at untreated restaurants was 11.5% after 4 weeks, a correction of the average reduction rate by applying the Abbot formula was 93.1%.

OBJECTIVETo evaluate the efficacy and safety of ruxolitinib in treatment of myeloproliferative neoplasm.

METHODSRandom clinical trials (~September 30, 2017) were identified from PubMed, Embase, Cochrane Library, Clinical Trials, CBM and Chinese Journal Full-text Database. The quality of RCT was assessed by Cochrane risk bias. Meta analysis was performed with Revman 5.3.

RESULTSRuxolitinib was efficacious in relieving splenomegaly (RR 49.12, 95% CI [15.81-152.59], P<0.001). The incidence of anemia significantly increased after ruxolitinib treatment (RR 1.71, 95% CI [1.05-2.77], P=0.16), while the thrombocytopenia (RR 1.04, 95% CI [0.50-2.16], P=0.92) and neutropenia (RR 2.46, 95% CI [0.91-6.61], P=0.07) had no statistical difference as compared with that in control group. Ischemia events had no significant difference as compared with control (RR 0.57, 95% CI [0.33-1.00], P=0.05). Infection events had no significant difference as compared with the control group (RR 1.18, 95% CI [0.79-1.78], P=0.24).

CONCLUSIONRuxolitinib is an efficacious therapeutic strategy on MPD with controlling splenomegaly. However,anemia events and bleeding events may threat its clinical safety, so more high quality RCT are needed.

Acute generalized exanthematous pustulosis (AGEP) is manifested by rapid development of many sterile, nonfollicular pustules on a background of edematous erythema. More than 90 percent of AGEP are induced by medication, mostly antibiotics. Drug patch test can be helpful in the diagnosis of AGEP. This paper reports the first case of celecoxib-induced AGEP confirmed by patch test in Korean literature.

OBJECTIVETo establish a high-performance liquid chromatography (HPLC)-based method for determining celecoxib concentration in the tongue tissue of hamsters.

METHODSCelecoxib mixed with the matrix (final concentration of 6%) was smeared on the surface of the tongue mucosa of hamsters, and the concentration and absorption rate of celecoxib in the tongue tissue were determined by HPLC at 5, 10, 15, 30, 60, 90, 120 min after the application.

RESULTSIn this system, the retention time of celecoxib was 4.4 min. Celecoxib concentration showed a good linear range within 25-800 microg/L (R2=0.9991, n=6), with the detection limit for celecoxib of 10 g/L (S/N=3). The extraction recoveries and method recoveries for celecoxib were 83.75%-90.01% and 91.98%-99.07%, respectively. The inter-day RSDs were 2.15%, 3.16% and 3.67%, and intra-day RSDs were 3.40%, 4.56% and 4.42%, respectively. The concentration of celecoxib in hamster tongue tissue within the first 120 min ranged from 0.685-/+0.019 microg/g to 3.168-/+0.143 g/g, reaching the peak level at 15 min.

CONCLUSIONCelecoxib can be rapidly absorbed through the tongue mucosa to reach a high concentration in the tongue tissue, indicating the possibility of oral COX-2 inhibitors to prevent oral cancer and precancerous lesions.

OBJECTIVETo study the apoptosis and mechanism of Fipronil on PC12 Cells.

METHODSThe effect of fipronil on the apoptosis and necrosis of PC12 cells of 3.13 x 10(-6), 1.25 x 10(-5) and 5.00 x 10(-5) mol/L three dose groups after 24 h treatment was detected by morphology and the apoptosis rate was detected by flow cytometer (FCM). The expression of Bcl-2 protein in PC12 cells of 3.13 x 10(-6), 1.25 x 10(-5) and 5.00 x 10(-5) mol/L three dose groups after 24 h treatment was measured by immunofluorescence.

RESULTSThe number of apoptotic cells of 3.13 x 10(-6) mol/L group was more than the control group examined by fluorescence microscope, and the number of dead cells of 5.00 x 10(-5) mol/L group was more than the control group. The apoptotic rates of PC12 cells was higher in the 3.13 x 10(-6) mol/L group than the control group measured by FCM, and the dead rates of PC12 cells was higher in the 5.00 x 10(-5) mol/L group than the control group (P < 0.05). Immunofluorescence cytochemistry experiment demonstrated that the level of Bcl-2 expression was significantly lower in the 3.13 x 10(-6) mol/L group than the control group.

CONCLUSIONAt low dosage, fipronil increases the apoptotic rates of PC12 cells possibly by decreasing the expression of Bcl-2 protein while at high dosage, fipronil only increases the amount of necrotic cells.
