Introduction: Opioid dependence is recorded as the most common drug of abuse in Malaysia. Currently, the preferred substitution therapy for most Government treatment centres is methadone used as substitution therapy for opioid dependence. There are, however patients who may benefit from being on the combined buprenorphine-naloxone formulation as substitution therapy instead. We discuss six cases of opioid dependence of varied backgrounds that were treated with buprenorphinenaloxone therapy and their outcomes. Discussion: All of the reported patients improved after the induction of buprenorphine- naloxone. Two of the cases highlighted the transfer of patients on methadone to buprenorphine-naloxone due to the adverse effect and interactions of methadone with other medications. During the transfer there were no major adverse reactions noted, and patients were safely able to continue with the maintenance therapy of buprenorphine- naloxone. Conclusion: Buprenorphine-naloxone is a safe and effective drug substitution therapy for opioid dependence. It has fewer interactions with other medications, and has similar efficacy to methadone. Being a partial agonist, it has a less sedating effect making patients more functional.

The alkaloid securinine was assessed against spore germination of some plant pathogenic and saprophytic fungi (Alternaria alternata, Alternaria brassicae, Alternaria brassicicola, Curvularia lunata, Curvularia maculans, Curvularia pallenscens, Colletotrichum musae, Colletotrichum sp., Erysiphe pisi, Helminthosporium echinoclova, Helminthosporium spiciferum, Heterosporium sp.). Spore germinations of all the tested fungi were inhibited. Alternaria brassicicola, C. lunata, C. pallenscens and H. spiciferum were highly sensitive as complete inhibition of spore germination was observed at very low concentrations (200 ppm).

OBJECTIVETo examine the therapeutic effect of combined use of obidoxime and atropine with artificial ventilation on respiratory muscle paralysis caused by omethoate poisoning in rats.

METHODSRats were exposed to 2 times the dose of LD50 omethoate and treated with atropine (10 mg/kg) to counteract cholinergic symptoms. When the rats' respiratory frequency became slower and breathed with difficulty, the trachea intubation and artificial ventilation was carried out. The rats in group A were continuously treated with atropine. The dose of obidoxime for Group B, C and D were 8, 15, 20 mg/kg respectively, given at the same time as artificial ventilation and 1, 2, 3 hours later. The doses of atropine was reduced to 1/3 - 2/3 of the first dose so as to maintain the rats atropinized. If the rat survival was beyond 60 minutes after withdrawal of artificial ventilation, the combined treatment was considered successful. The function of isolated phrenic diaphragm of the rats was observed with MS-302 physiological and pharmacological analysis instrument.

RESULTSNone of the rats in Group A was successful after withdrawal from artificial ventilation and the function of phrenic diaphragm appeared poor; whereas > 80% of the rats in B, C, D Group were successful after withdrawal from artificial ventilation in 3 h and the function of phrenic diaphragm remained well. The survival rate in B, C and D groups were higher after withdrawal from artificial ventilation than that in Group A(P < 0.01). The function of phrenic diaphragm in Group B, C and D were gradually decreased after ACh was added into the container.

CONCLUSIONSCombined use of suitable dose of obidoxime and atropine with artificial ventilation for respiratory muscle paralysis caused by omethoate poisoning could promote the recovery of diaphragm function and reduce the death rate in poisoned rats.

OBJECTIVETo evaluate the efficacy and safety of tiotropium in treatment of severe persistent asthma.

METHODSReports of randomized controlled trials (RCTs) describing tiotropium for treatment of severe persistent asthma published from January 1946 to February 2015 were searched in Cochrane Library, ClinicalTrials.gov, PubMed, Ovid Medline, CNKI, and CSJD. The data of the included RCTs were extracted and the data quality was evaluated. Meta-analyses were performed with Revman 5.3 software.

RESULTSFive RCTs including 1433 patients were analyzed. Meta-analysis of the data showed that compared with the placebo group, tiotropium treatment significantly improved the patients' peak forced expiratory volume in one second (FEV1) [weighted mean difference (WMD): 0.13 L, 95% confidence interval (CI): 0.10-0.16 L, P<0.00001], trough FEV1 (WMD: 0.09 L, 95%CI: 0.06-0.12 L, P<0.00001), peak forced vital capacity (FVC) (WMD: 0.10 L, 95%CI: 0.06-0.14 L, P<0.00001), trough FVC (WMD: 0.12 L, 95%CI: 0.08-0.17 L, P<0.00001), morning peak expiratory flow (PEF) (WMD: 9.21 L/min, 95%CI: 4.2-14.23 L/min, P=0.0003), evening PEF (WMD: 22.06 L/min, 95%CI 13.05-31.08 L/min, P<0.00001). The scores of asthma control questionnaire (ACQ) (WMD: 0.01, 95% CI: -0.07-0.09, P=0.86) or asthma quality of life questionnaire (AQLQ)(WMD: 0.06, 95% CI:-0.18-0.06, P=0.33) were not affected by tiotropium. No significant difference with adverse events between tiotropium group and placebo group were reported in these included studies (P>0.05).

CONCLUSIONSTiotropium for severe persistent asthma treatment can improve FEV1, FVC, and PEF but may not improve the quality of life of the patients. Tiotropium is well tolerated and can be an add-on therapy for severe persistent asthma.

AIMTo study the in vitro and in vivo metabolism of (-)-securinine.

METHODSThe metabolic transformation of (-)-securinine was studied by using phenobarbital-induced rat liver microsomal incubate containing the NADPH-generating system in vitro and the constitution of the system was optimized. A reversed phase HPLC method was established to analyze the parent drug and its metabolites. The major metabolites were isolated and purified by liquid-liquid extraction, preparative TLC and HPLC, and their structures were elucidated as 6-hydroxyl securinine, 6-carbonyl securinine, 5 beta-hydroxyl securinine and 5 alpha-hydroxyl securinine by 1HNMR, 13CNMR and MS spectral analysis. An HPLC method was developed to analyze securinine and its metabolites in biofluids (bile, urine) of rat. The bile, urine and their enzymatic hydrolyzed samples of the rat i.p. administrated with (-)-securinine were determined by using this method.

RESULTSFour main metabolites of (-)-securinine in rat hepatic microsome incubation were obtained and their structures were elucidated. Metabolites from in vitro study were confirmed in biofluids (bile, urine) which were collected from rats given securinine i.p. It was suggested that 6-hydroxyl securinine was excreted in conjugated form as well by analyzing enzymatic hydrolyzed bile.

CONCLUSIONThe main metabolic pathway of (-)-securinine in vitro and in vivo is basically elucidated.
