Augmentin is a formulation of amoxycillin trihydrate and potassium clavulanate, a fused beta-lactam molecule produced by the fermentation of Streptomyces clavuligerus. Most clinically important resistance is due to the production by bacteria of antibiotic destroying enzymes. In the case of penicillins and cephalosporins these enzymes are termed beta-lactamase as they destroy the beta-lectern ring of these antibiotics, completely inactivating them. The presence of clavulanic acid extends the spectrum of amoxycillin to include bet On clinical study of the intravenous Augmentin in the field of thoracic and cardiovascular surgical cases, we selected randomly 30 patients, 21 male and 9 female, age from 13 to 72, in the period from April to December 1985. Among the total 30 patients, 22 were preoperatively infected [11 thoracic empyema, 5 lobar pneumonia, 2 lung abscess, 2 bronchiectasis, one acute pyelonephritis with ureter stone and one rheumatic carditis], and 8 were not infected preoperatively [Table 1, 2]. Of the preoperatively infected group, 11 cases [50%] were culture positive [4 staphylococcus, 3 pseudomonas, 2 Serratia group, and one E. coli], and preoperatively non-infected group [8 cases] revealed expectedly negative findings on bacterial culture. All of the culture positive bacteria were sensitive to Augmentin on disc culture sensitivity test except one case of E. coli. Daily doses of intravenous Augmentin were 2.-1-6.0gm divided in 2-5 injections. Every injection administered [1.2gm at Augmentin dissolved in 20ml distilled water] slowly for more than 20 minutes. Duration of injection was variable according to the clinical conditions from minimum 5 to maximum 31 days. The results of antibiotic treatment with Augmentin and some other antibiotic combinations pre- and postoperatively were subgrouped as EXCELLENT, EFFECTIVE, and FAILURE. Clinical criteria of the therapeutic result were symptomatic, objective and laboratory improvement. 8 cases were excellent, 13 effective, and one failure among the preoperatively infected group, and all 8 cases of the preoperatively non-infected group were effective as pro;hylactive antibiotic therapy. Overall effective ratio was 97% in both subgroup. There was no side effect clinically and laboratory study including liver and kidney function test during and after the I.V. administration of Augmentin. Oral swallow tablets which were administered after discharge from hospital also revealed good effects with some degree of gastrointestinal trouble.

Strains of bacteria resistant to beta-lactam antibiotics have been increasing in number and are becoming troublesome in clinical medicine. The in vitro antibacterial activity of augmentin, a combination drug consisting of two parts amoxycillin to one part clavulanic acid, a potent beta-lactamase inhibitor, and their minimum inhibitory concentrations were determined by an agar dilution technique against ampicillin-resistant clinical isolates in Korea. Of the 226 strains tested, 140 strains(62%) were resistant to ampicillin. Among the 140 ampicillin-resistant strains, all Salmonella spp. Proteus spp. the majority of S. aureus and Shigella spp. were sensitive to augmentin. Ps. aeruginosa remained 100% resistant and there has been a considerable decline in resistant strains in E. coli and K. pneumoniae although a significant percentage of strains showed intermediate sensitivity. The minimum inhibitory concentrations of augmentin were ranged in $8{\mu}g/ml$ to $32{\mu}g/ml$ in most bacteria and all S. aureus were inhibited by $8{\mu}g/ml$. In our microbiological studies we have shown that augmentin is active against ampicillin-resistant strains of Staphylococci and Gram-negative bacteria. In this hospital there would appear to be a significant number of strains of E. coli and K. pneumoniae showing intermediate resistance to augmentin. Most of these strains should be susceptible to augmentin given by mouth or by the intravenous route depending on the concentrations of both amoxycillin and clavulanic acid obtainable in the various tissues.

SM-101 is a mixture of metampicillin and sulbactam(2:1). The antibacterial activities of SM-101 were compared with those of metampicillin, piperacillin and Augmentin. It showed powerful antibacterial activities against major strains. Except P. anruginosa and S. marcescens, the in vitro antibacterial activity of SM-101 was higher than those of metampicillin, piperacillin and Augmentin against Staphylococcus spp., Streptococcus spp., Moganella morganii, E. Coil, and Proteus spp. The $ED_{50}$ values of SM-101 were two-fold or greater than those of metampicillin, piperacillin and Augmentin against $\beta-lactamase$ producing strains, p. mirabilis GN79 and M. morganiii MB4-11. The in vivo efficacy of SM-101 was more active than metampicillin and pipeeracillin and similar to Augmentin against S. aureus Smith, E coli MB4-01 and K. pneumoniae MB4-02.

The aim of this study was to determine the minimal inhibitory concentration(MIC) of cefixime, which is a 3rd generation of cefalosporin, against 6 species of putative periodontopathogens; Fusobacterium nucleatum, Actinobacillus actinomycetemcomitans, Prevotella intermedia, Prevotella nigrescens, Tannerella forsythia and Porphyromonas gingivalis. The efficacy of cefixime was examined by comparing it with that of several antibiotics(amoxicillin, $Augmentin^{(R)}$ ciprofloxacin, metronidazole, and tetracycline), which were used as the control. The MIC was measured using a microdilution method. The MIC of cefixime against the putative periodotopathogens, as a single use regimen, was relatively lower than that of the other antibiotics. The MIC of cefixime/metronidazole against P. intermedia ChDC KB14, P. nigrescens ChDC KB50, F. nucleatum ChDC PV-F37, F. nucleatum ChDC F130, and F. nucleatum ChDC F175, as a simultaneous regimen, was lower than that of the other antibiotics. The concentration of cefixime in the crevicular fluid of volunteers who received 250mg every 12 hours for 3 days was $9{\mu}g/ml$ after 9 hours. In conclusion, cefixime showed good antimicrobial activity in a single treatment or as a combined therapy with amoxicillin, $Augmentin^{(R)}$ or metronidazole against 6 periodontopathogens.

To evaluate the efficacy of antibiotic administration in the impacted mandibular third molar extraction the author investigated 107 patients requiring extraction of the lower third molar who visited at the Department of oral and maxillofacial Surgery, Chosun Dental Hospital and were healthy without medical problems and had no signs and symptoms of infection around the lower third molar. The patients were divided into 4 groups according to the method of antibiotics administration: 13 patients without antibiotics administration(group 1), 30 patients with only intravenous injection of $Cefazoline^{(R)}$ 2.0g 30 minutes before the procedure(group 2), 39 patients with intravenous injection of $Cefazoline^{(R)}$ 2.0g 30 minutes before the procedure and oral administration of follow-up dosages of $Augmentin^{(R)}$ for 1 day(group 3), and 25 patients with intravenous injection of $Cefazoline^{(R)}$ 2.0g 30 minutes before the procedure and oral administration of follow-up dosages of $Augmentin^{(R)}$ for 3 day(group 4). Infection rates after extraction were calculated and compared according to gender, the age of the patients, the level of impaction, and also compared between four groups. The results were as follows. 1. The overall infection rate was 8.4%. 2. The infection rate was higher in male(11.9%) than in female(4.2%), but there were statistically no significant differences between them. 3. Infection rate was lower in patients under age 30(7.2%) than in patients over age 30(12.5%), but there were statistically no significant between them. 4. Infection rate was higher in patients with complete bony impacted tooth(11.1%) than in patients with partial bony impacted tooth(6.5%), but there were statistically no significant differences between them. 5. Infection rate was 7.7% in group 1, 10.0% in group 2, 10.3% in group 3, 4.0% in group 4 and there were statistically no significant differences between groups. In summary, it is more important to extract the impacted lower third molar under aseptic condition and to minimize the injury of tissue if possible than to administer the preventive antibiotics in reducing the infection rate in healthy patients without medical problems who had no signs and symptoms of infection around the lower third molar.

Mitis-salivarius sucrose bacitracin(MSB) medium is widely used in the selective isolation of mutans streptococci(MS), a designation for a group of oral cariogenic species. Recently, we have isolated three bacterial strains grown on MSB agar from human dental plaques. The three strains exhibited biochemical characteristics similar to those of the biotype IV of MS, with the exception that they manifested a positive reaction for arginine deaminase. The objective of this study was to identify and characterize these three clinical isolates. The bacteria were identified with biochemical tests as well as by 16S rDNA cloning and sequencing. In order to compare the antibiotics susceptibility of the clinical isolates with that of type strain, the minimum inhibitory concentrations of 9 antibiotics were determined using broth dilution assays. The results identified all of our three clinical isolates as Enterococcus faecalis. All E. faecalis strains were found to be susceptible to penicillin G, amoxicillin, augmentin, and vancomycin, but were resistant to ciprofloxacin, cefuroxim axetil, and clindamycin. Our findings indicate that E. faecalis is capable of growing on MSB agar, and suggest that the MSB medium be improved so that only MS should be recoverable on the medium, as originally devised for their selection.

Generalized anaphylaxis is a most dramatic and acutely life-threatening allergic reaction and may cause death within a few minutes. Differential diagnosis of anaphylaxis is made by clinical signs, such as, mental change, respiratory distress, hypotension, hypoglycemia, urticaria and angioedema. Especially, insulin reaction, myocardial infarction and vasovagal syncope are considered as differential diagnosis. In cases of fatal anaphylaxis, respiratory and cardiovascular disturbances predominate and are evident early in the reaction. This is a case report of the intensive care of anaphylactic shock after intravenous injection of the penicillin in a old medically compromised patient with the maxillary osteonecrosis. The anaphylactic shock symptoms, such as, unconsciousness, respiratory disorder, no pulsation on carotid artery and cardiopulmonary arrest are occurred in intravenous injection of augmentin 1.2 g after the skin test. In spite of immediate emergency cares, such as intravenous injection of epinephrine, endotracheal intubation, cardiopulmonary resuscitation, and continuous intensive care, the patient is expired in 58 hours after anaphylactic shock attack.
