  • 개선충증의 발생을 예방하기 위해서는 1년에 가을과 봄 2회에 걸쳐 구제제를 투약하는 것이 좋다. 개선충증이 이미 발생한 뒤 치료하는 경우는 예방을 목적으로 정기적으로 구충하는 경우보다 경제적인 손실이 더욱 크다. 돈군내 개선충이 전혀없거나 개선충으로 인한 피해가 전혀없는 경우를 제외하고는 개선충으로 인한 경제적 손실을 예방하기 위해서 규칙적인 예방적 치료를 행하는 것이 더욱 좋다

  • 등부표는 태양광발전을 이용한 독립형 전력계통시스템으로 일사량과 표면온도에 의한 태양광 발전효율 저하에 따른 등명기 소등 또는 광력 미약으로 항로표지에 대한 신뢰성 확보에 대한 문제점이 발생하고 있다. 일부 항로표지용 고효율 충방전조절기 제품이 개발되고 있으나 "항로표지 장비 용품 표준화 규정"의 항로표지용 충방전조절기 표준규격(제3조3호)이 제정고시 되어 충방전조절기의 기능 및 성능개선을 추진할 필요가 있다. 본 연구에서는 개정된 충방전조절기의 표준규격의 성능을 만족하고 상용화가 가능한 구조기술을 개발하였다.

  • A 3-year-old, male, mongrel dog was presented with pruritus, alopecia to the Veterinary medical Teaching Hospital, College of Veterinary Medicine of Kyungpook National University. On physical examination, generalized erythema, papules, scales and crusts were observed. The canine scabies infestation was diagnosed by deep skin scraping and Malassezia spp. and Staphylococcus spp. were found on skin cytology. He was treated with selamectin at 6 mg/kg applied to the skin in a single spot every two weeks for one month in order to investigate the effect of selamectin on canine scabies and was treated with amoxicillin trihydrate/clavulanate pattassium, ketoconazole and chlorhexidine shampoo for Malassezia sup. and Staphylococcus spp. simultaneously. When he was rechecked after 7, 14, 21, and 28 days after the first application of selamectin, scabies werent seen. The dermatological signs including pruritus, papules, scales, and crusts were remarkably resolved at 14 days. The alopecia was almost disappeared and few Malassezia spp. and Staphylococcus spp. were seen after 28 days. The efficacy of selamectin by this protocol is excellent in the dog infestated canine scabies.

Efficacy of Twice a Week Selamectin Application as a Treatment for Mixed Canine Scabies and Ear Mite Infestation in a Dog (개에서 피부개선충(Canine Scabies)과 귀진드기(Ear Mite) 혼합감염에 대한 주 2회 selamectin 적용 일례)

  • A 6-month-old, male, American cocker spaniel was presented with severe pruritus, alopecia and head shaking. In physical examination generalized erythema, papules, scales and crust were observed. Otic discharge was dark-brown colored in both ear canals. After extensive dermatologic diagnostic evaluations, the infestation of scabies, ear mites, Malassezia spp, cocci were proved. Therefore, he was treated with selamectin 6 ㎎/㎏ which was applied to the skin in a single spot twice a week for 2 weeks in order to investigate the effect of selamectin on canine scabies and ear mites by this treatment protocol. When he was rechecked at 14th day after fourth being administered, scabies and ear mites wasn't seen. The dermatological signs, pruritus, papules were remarkably decreased and only slight scales were observed. After treatment of scabies and ear mites, the clavamox and koto-conazole was administered for cocci and Malassezia spp, respectively, for 1 week and topical therapy was initiated. with sebolytic and chlorhexidine shampoo once a week for 3 weeks. Two months later skin lesions were normal dermatologically and the hair was fully recovered. Despite of the expensiveness the selamectin is very effective in the dogs that infected by scabies and ear mites as this treatment protocol.
