"The Islamic Iran ranks first in science in the region," Hosseini said, addressing a forum in Ilam city, Western Iran, on Friday.
Stressing that Iran has overcome all problems and pressures exerted on the country by the western powers during the last three decades, he said that the Islamic Republic is growing more powerful in the region and the world day by day.
Iran has taken wide strides in science and technology, particularly in medical and medicinal fields, in recent years.
In January, Iranian President Mahmoud Ahmadinejad in a ceremony in Tehran unveiled 6 new types of home-made medicines used for treating various kinds of diseases.
The Iranian president unveiled 2 new types of drugs and 4 types of raw materials for treating osteoporosis, hemophilia and neurological, skin and muscle diseases and breast cancer.
Iranian scientists had also in 2011 managed to produce a new type of anti-cancer drug using the venoms of reptiles like snakes and scorpions.
"After several years of research and studies on a combination of snake and scorpion venoms, the anti-cancer drug was produced in Iran," Abbas Zare', the Director of the Venomous Animals Department of Iran's Razi Vaccine and Serum Research Institute, told reporters in October.
"This anti-cancer drug has been produced from snake and scorpion venoms after 10 years of research work and has been extracted from the fat (peptide) of such animals," he added.
