JERUSALEM, Sept. 6 (Xinhua) -- An Israeli university said on Thursday that its researchers have developed a drug for effective treatment of osteoporosis.

Osteoporosis, a disease in which bones become brittle and fragile, is caused by a disturbance in the balance between the formation of new bone tissues and the dissolution of old bone tissues.

The researchers from Ben-Gurion University demonstrated the drug's effectiveness in delaying bone dissolution.
