Thioether derivatives of tylosin and demycarosyltylosin were synthesized by Michael-type addition of thiol to C-11 of the enone moiety on the aglycone. Some of tylosin derivatives were effective to macrolide resistant Staphylococcus aureus, and their in vivo activities were same or superior than that of tylosin.

Varicella spread from a child with zoster to a total of 3 susceptible infants in another room in a children's ward, although they had been strictly isolated. To prevent spread of the disease, the staffs and patients were doing their own washing and no source of natural infection could be found. The cases indicate that it is difficult to predict nosocomial varicella infection or to prevent spread of the disease simply by isolation in a children's ward. A total of 11 other children without history of varicella in the ward were given live varicella vaccine before or immediately after this event. None of these children developed symptoms of varicella and all the susceptible children who were vaccinated showed an antibody response.

Oral sustained release cephalexin (S-6437) was administered to 24 pediatric patients. Daily dose used was 18 approximately 60 mg/kg, which was divided into two doses and given after breakfast and dinner. The following are the results of the study. Out of 24 patients, 6 showed very good response, 10 good response, 6 fair, 1 poor and 1 unknown, Ratio of effectiveness was 69.6%. Two patients were reluctant to receive the drug and, therefore, they took other drugs. The other 22 patients, however, were easily given. No remarkable side effects due to S-6437 were found. From the above results, it was recognized that S-6437 has good effectiveness and safety, and it is convenient to give to children because the frequency of the drug administration is only twice a day.
