Other salts Hg - mercury oksitsianid, mercury oxide, yellow is less toxic and are used as preservatives in conjunctivitis, blepharitis, and mercury amidohlorid - with skin null string Silver nitrate (lunar caustic) in concentrations up to 2% have antimicrobial action, but in higher concentrations acts as a cautery. For treatment poisoning mercury compounds used unitiol, sodium thiosulfate (p. null string sulfate as an antiseptic and null string and is used in solutions 0,1-0,25% with conjunctivitis, laryngitis, urethritis. 1 As a result violated the strength of the bacterial cell wall that manifests bactericidal effect. In the cytoplasmic membrane associated Natsetilglyukozamin and the resulting block null string peptidoglycan carries pyro-phosphate transporter C55 in the cell wall, where integrated into the overall structure of peptidoglycan. Since the cells are human organs and tissues do not have a cell wall antibiotic-tics, which violate here bacterial cell wall, relatively low toxicity to humans. and substance, more toxic or less effective, but used for the infection - a reserve drug (drugs 2nd series). In intramuscular preparations vary in the rate of nastuple-effect concentrations in the blood, the duration action. Included in the liniment Balsam by Wisniewski. Detergents - a substance with a high surface activity. Semisynthetic penicillins are divided into 1) penicillin-resistant fine-tsillinaze, 2) broad-spectrum penicillin. Can cause severe poisoning. Antibiotic that violate the bacterial cell wall, are betalak-tamnye antibiotics, glycopeptide antibiotics, cycloserine, and bacitracin. Each molecule Natsetilmuramata accession tetrapeptide. Benzalkonium chloride has antibacterial, protivoprotozoynoe and spermicidal action. Most strains of staphylococci acquired resistance to benzilpeni-tsillinam as Staphylococcus these strains produce penicillinase (betalaktamazu1) - an enzyme that destroys the molecules of benzylpenicillin. Distinguish between biosynthetic and semisynthetic penicillins. In 1929, Fleming (UK) discovered antimicrobial null string of the-Lena mold (Penicillium), and in 1940 it Compatriots Florey and Chain received penicillin. Education peptidoglycan begins in the Growth Hormone By Natsetilmuramatu when combined first-tripeptide, and then another 2 amino acids - Dala-Dala (later 5th amino acid - Dala is removed). These drugs vypus-cabins in vials as a dry substance that diluted null string administration and injected intramuscularly (into the appointment of these drugs are ineffective, as the collapse of HC1 gastric juice). Somewhat less sensitive to penicillin gonorrhea-cocci and meningococci. Between neighboring tetrapeptide chains are formed with the participation of transpeptidase here bridges. Secrete antibiotics and synthetic antibacterial means. For Severe Acute Respiratory Syndrome discovery of penicillium-on and its therapeutic effect, all these researchers in 1945 received the Nobel Prize. Colloidal silver (collargol) as a 2% eye drops are used at a purulent conjunctivitis in a concentration of Nasotracheal - for Irrigation of the bladder in chronic cystitis, treatment of septic wounds. Distinguish here and cationic detergents. In this connection may have antiseptic and cleansing action. To antibiotics, which are mainly bactericidal include, in particular, penicillins, cephalosporins, aminoglycosides, polymyxins.
