  • Deterioration and brittleness of resources on the shelves of institutions such as libraries and archives have been increased and accelerated as time passes in accordance with the preservation environment and the nature of their own material. It can be a loss of current information with little importance in prolong the life of valuable materials and to preserve them in security, integrated preservation programs should be developed and implemented according to missions, sizes, the nature of collections, users, and budgets of individual institutions. In reality, most institutions, however, are not able to implement perfect preservation programs due to lack of budget, human resources, and expertise. To solve this problem, some institutions in similar circumstances have planned cooperative preservation programs in various levels. Through cooperative systems individual institutions can not only pursue common interests but gain real benefits for themselves. Consequently institutions are recommended to collaborate with in development and implementation of various preservation programs at local, national, and international levels in addition to individual institutional programs.

  • 2, 3-Diphenyl-6-formyl-5-methoxyindole reacts with ethyl cyano acetate to yield the arylidene derivative which forms with urea and thiourea the corresponding pyrimidine derivatives. The arylidene derivatives react with hydrazines and with active methylenes to form the respective pyrazole derivatives and the $\alpha, \;\beta$-disubstituted acrylonitriles. Seven new compounds were tested for their effects on the arterial blood pressure of rats and analgesic activity.

  • Alcohol extracts of plants widely used in the traditional medicine have been tested to establish if they affect the metabolism of drug in mice. Forteen of the plants tested exhibited prolonging and/or inhibitory effect on hexobarbital sleeping time. Some of them also showed increasing effect on strychnine mortality, whereas piperis retrofracti Fructus reduced the toxicity of strychnine.
