| On a new aerobic metabolite whose production by brain is inhibited by apomorphine, emetine, ergotamine, epinephrine, and menadione. |
| Hepatoma-bearing rats receiving intraperitoneal injections of menadione demonstrated an increased survival rate of 60 days compared to 17 days for controls. |
| Victor Oreffo presented results on gene expression analysis following in vivo or in vitro exposure to the oxidative stress agents menadione and diquat. |
| After absorption, menadione is thought to become alkylated into biologically active isoprenylated menaquinones. |
| The K vitamins exist naturally as K 1 in green vegetables and K 2 produced by intestinal bacteria and K 3 is synthetic menadione. |
