Correlation between the protease activities and the number of epithelial cells in human saliva

The positive significant correlation (r = 0.788, n = 37) was shown between the protease activity and the number of epithelial cells (not of leukocytes) in saliva. There was little protease activity observed in glandular saliva. It is possible to conclude from the results that a main source of salivary protease is the epithelial cells in saliva. It was also found that the oral prophylaxis reduced the numbers of epithelial cells and leukocytes and the protease activity.

[The comparison of blood levels between peripheral vein and tooth extraction wound after the oral administration of antibiotics (author's transl)]

The oral administration of 300 mg of clindamycin was undertaken on 23 patients, of 500 mg of cefadroxil on 11 patients and of 250 mg of talampicillin on 12 patients, and then tooth extraction was performed under local anesthesia. Blood samples were taken from the extraction wound and the peripheral vein at the same time and assayed by the bioassay method. The blood levels of clindamycin and cefadroxil indicated a similar pattern between the extraction wound and the peripheral vein, but the blood level of talampicillin reached peek level rapider than clindamycin and cefadroxil. The blood levels of the extraction wound were 60 - 80% as compared with the venous blood levels with each antimicrobial agent.

Surgical correction of double outlet left ventricle associated with hypoplastic right ventricle: direct anastomosis of right atrial appendage and pulmonary artery

This reports concerns a 9 years old boy, who had situs solitus and atrioventricular concordance with double outlet left ventricle, pulmonary stenosis, tricuspid stenosis, ventricular septal defect, secundum atrial septal defects and hypoplastic right ventricle. Previous Blalock-Taussig shunt was created at the age of 11 months. Total correction consisted of closure of atrial septal defect and tricuspid valve orifice, and direct anastomosis of right atrial appendage to pulmonary trunk. Though atrial pacing was required for the immediate post operative period, the patient regained sinus rhythm 3 days after operation. He is doing well at present, one year after the operation.

Blood flow and pressure measurements of right coronary artery to left ventricle fistula

A case of a dilated and tortuous right coronary artery to left ventricle fistula was surgically repaired. Preoperative intracoronary pressure measurements showed a sudden depression of diastolic pressure in the terminal part of the right coronary artery. Intraoperative mean right coronary flow was recorded as 315 ml/min. After repair of the fistula, blood flow measurements showed only 35 ml/min, which suggested that a large amount of blood was stolen by the fistula. Although systolic and diastolic murmurs only were heard in our patient, continuous murmurs have been noticed by some observers. From a study of the preoperative physical findings, intraoperative coronary flow measurements, and other operative findings, the genesis of heart murmurs relating to this type of anomaly is discussed.

Tooth extraction in a patient with Glanzmann's thrombasthenia

A 14-year-old Japanese boy suffering from Glanzmann's thrombasthenia required extraction of two permanent teeth and one primary tooth. This report deals with the details of the procedure and discusses the effect of platelet transfusion and local management in tooth extraction of patients with this hemorrhagic diathesis.
