25-Hydroxyvitamin D (25-OHD) is the most appropriate marker for monitoring vitamin D storage status. The 2 major forms of 25OH-D [25-OH-D2 (D2) and 25OH-D3 (D3)], differ slightly in molecular structures but have essentially the same physiological activity. Therefore, both D2 and D3 should be measured to assess vitamin D status. At our laboratory, 42% of patient samples submitted for vitamin D t...

Intraperitoneal (IP) injection of bupropion (3,6, amine (4,16 mg kg•') induced dose-dependent climbing in mice. The climbing response induced by both drugs were decreased in animals pretreated either with the 0-1 antagonist SCH 233<)0 or the 0-2 antagonist sulpiride. The α-adrenoceptor blocker phenoxybenzamine decreased the climbing induced by both bupropion and amphetamine, but the β-ad...
