Atenolol in the treatment of angina pectoris.

Nineteen men, aged 41-64 years, with stable angina pectoris have completed a random double-blind study of atenolol, 50 mg b.i.d.

The visibly fluorescent phospholipids of serum lipoproteins.

The blusih-white fluorescence exhibited by lipoproteins from human serum has been investigated. It appears that high-density lipoprotein (HDL), low-density lipoprotein (LDL), and very low density lipoprotein (VLDL) all exhibit this fluorescence with excitation maximum at about 360 nm and fluorescence maximum at about 450 nm. The fluorescence resides in the phospholipid fraction of the lipoproteins and is not located in the fatty acids, since the water-soluble deacylated phospholipid fraction exhibited the same fluorescence.
