Korean Cleft Lip and Palate Association (KCLPA) was founded in 1996. The first overseas charity operation was in Karachi, Pakistan, 2002 and our association has visited fourteen times in six countries for the free cleft surgery: Pakistan, Egypt, Kenya, Morocco, Jordan and Vietnam. The cumulated number of operated patients reaches to 280. Before our association, many Korean oral and maxillofacial surgeons have performed charity operations individually since 1964. It was started from Vietnam but the activity is now carried on in Africa, middle-east Asia, south-east Asia, China, and Korea as an official team. LG electronics, a Korean company helped to propagate our team's activity to middle-east Asia to Africa. This paper is a report concerning about the results of our association's charity activities especially in Kenya, east Africa. We provided free cleft surgery for 30 patients in 2004 and 27 patients in 2005, in Nairobi. As the blood test for HIV of the cleft patients was not allowed before and during surgery, our surgeons and nurses were cautious about every movement during the surgeries. Thus the operation time for each patient was longer than any other time. The attitude of the local hospital and the doctors seemed to be accustomed to this situation. They helped us in case of needle injuries. Safety of medical staff and patients is more important than the number of the patients operated in charity operation. This belief should be approached being parallel and multidisciplinary as an international cooperation, focusing on international funding for medical support and continuous education for local doctors who are willing to devote to their people.

It is well known fact that antibiotic residues in milk of cows create significant problem for the fermented dairy industry and public health because of inhibition of starter activity and of creation of allergic disease. It can be assumed that antibiotic residues in milk of other aniimals also can create some problems for their infants as in the case of humen. For the above mentioned reasons, present studies were undertaken to determine concentration and duration of antibiotic residues in milk of cows, goats and dogs following intramuscular or intravenous injection and intramammary infusion of penicillin, streptomycin and oxytetracycline at usual dosage. The cylinder-plate method was used for their assay. The results obtained were summerized as follows: 1) Following the intramuscular injection of penicillin, the antibiotic was detected in milk of cows up to 72 hours, in milk of goats 48 hours and in milk of dogs 60 hours of postinjection. The mean peak concentrations were recorded at 12 hours as 0.136 I.U./ml in cows. 6 hours as 0.773 I.U./ml in goats and 3 hours as 1.192 I.U./ml in dogs. 2) Following the intramuscular injection of streptomycin, the antibiotic was detected in milk of cows and goats up to 36 hours and in milk of dogs 24 hours of post-injection. The mean peak concentration were recorded at 6 hours as $0.26{\mu}g/ml$ in cows and at 3 hours in goats and dogs $0.45{\mu}g/ml$ and $0.36{\mu}g/ml$ respectively. 3) Following the intra venous injection of oxytetracycline, the antibiotic was detectable in milk of all the test animals up to 48 hours of postinjection. The mean peak concentrations were recorded at 6 hours as $3.5{\mu}g/ml$ in cows $2.4{\mu}g/ml$ in goats and $2.0{\mu}g/ml$ in dogs respectively. 4) Following intrarnammary infusion of penicillin in amounts of 100,000 I.U. for cows, 20.000 I.U. for goats and 10,000 I.U. for dogs, the penicillin residues in milk of the infused quarter perssisted to 72 hours in cows and 84 hours in goats and dogs. 5) Following intramammary infusion of streptomycin in amount of 500mg for cows, 100mg for goats and 25mg for dogs, the streptomycin residues in milk of the infused quarter persisted to 72 hours in cows and goats and 60 hours in dogs. 6) Following intramammary infusion of oxytetracycline in amount of 500mg for cows, 100mg for goats and 25mg for dogs, the oxytetracycline residues in milk of the infused quarter persisted to 72 hours in cows and 60 hours in goats and dogs. 7) A corelation between the residual antibiotic concentration and milk yield in cows and goats was observed; That is, the lower in the milk production showed a higher the concentration of an antibiotic residues and a longer the time in persistance. 8) Intramammary transfer of the antibiotic from an infused to non infused quarters, in dogs, was observed following the intramammary infusion of penicillin. streptomycin and oxytetracyclne in amounts of 10.000 I.U. 25mg and 25mg respectively. However, no transfer by 100.000 I.U. or 20.000 I.U. of penicillin. 500mg of streptomycin and 100mg of oxytetracyline was observed in cows and goats. 9) In dogs, minimum dosage of antibiotics for transfer fro in treated to untreated quarters following intramammary infusion were 2,500 I.U. of penicillin and 5mg each of streptomycin and oxytetracycline.
