24105105-2	2014	Our previous study showed the effect of Vit B12 on morphine tolerance.	Morphine	51-59	vitrin	Mus musculus	40-43	
24105105-9	2014	Co-administration of Vit B12 (100-500 microg/kg) and morphine in 3 days reduced the development of tolerance to morphine analgesic effect (8.2+-0.5 and 7.83+-0.5 s. vs. normal saline, 3.57+-0.3 s).	Morphine	112-120	vitrin	Mus musculus	21-24	
24105105-12	2014	It is concluded that co-administration of Vit B12 and morphine could reduce tolerance to analgesic effect of morphine chronic administration and also reduce its withdrawal symptoms.	Morphine	109-117	vitrin	Mus musculus	42-45	
22588629-8	2012	Vit B12 showed a dose related effect in acute anti-nociceptive test and increased the anti-nociceptive effect of morphine in chronic treatment.	Morphine	113-121	vitrin	Mus musculus	0-3	
22588629-9	2012	Vit B12 demonstrated an anti-nociceptive effect in chronic studies as single or continues daily treatment and increased significantly the anti-nociceptive effect of morphine.	Morphine	165-173	vitrin	Mus musculus	0-3
