= Acute effects of these drugs include a fall in peripheral resistance

~ Vasoconstriction
~ Reduction of the release of renin

237. 
     Mechanisms of bacterial resistance to anti-microbial agents are the following, EXCEPT:
     

1. 
   ~ Active transport out of a microorganism or/and hydrolysis of an agent via enzymes produced by a microorganism
   

2. = Enlarged uptake of the drug by a microorganism

3. 
   ~ Modification of a drug’s target
   
4. 
   ~ Reduced uptake by a microorganism
   

237. 
     The statement, that some microorganisms can develop alternative metabolic pathways for rendering reactions inhibited by the drug, is:
     

     1. = True

     2. 
        ~ False
        
238. 
     All of the following drugs are antibiotics, EXCEPT:
     
     1. 
        ~ Streptomycin
        
     2. 
        
     3. 
        ~ Penicillin
        

     4. = Co-trimoxazole

239. 
     Bactericidal effect is:
     
     1. 
        ~ Inhibition of bacterial cell division
        
     2. 
        ~ Inhibition of young bacterial cell growth
        

     3. = Destroying of bacterial cells

     4. 
        ~ Formation of bacterial L-form

        ~ All of the above
        
241. 
     Bacteristatic effect is:
     

     1. = Inhibition of bacterial cell division

     2. 
        ~ Inhibition of young bacterial cells growth
        
     3. 
        ~ Destroying of bacterial cells
        
     4. 
        ~ Formation of bacterial L-form
