The present experiment was investigated to compare tretment effect of drug therapy, acupuncture therapy, the combination of acupuncture and drug therapy, and electro-acupuncture therapy using 152 calves with respiratory deseases. Among 20 cases of drug therapy group, 16 cases (80%) were recovered and 4 cases (20%) were ineffective. Among 28 cases using Su Qi in acupuncture therapy group, 21 cases using San Tai, An Bi and Fei Shu, 17 cases (72%) were available and 7 cases (28%) were unavailable. Among 28 cases of the combination group of acupuncture and drug therapy, 24 cases(86%) were recovered with the highest tretment effect in Su Qi and drug therapy. In addition, among 24 cases of the combination group of acupuncture and drug therapy, 20 cases(84%) were effective and 4 cases (16%) were ineffective with lower effective rate compared by Su Qi and drug therapy in San tai, An bi and Fei shu and drug therapy. And among electro-acupuncture group using Fei Shu $[left({\ominus}), right({\oplus})],$ 22 cases (82%) were effective and 6 cases (18%) were ineffective.

전자담배는 무니코틴성이 있는 한편, 니코틴이 함유되어 있는 금연도구로서 사용된다. 전자담배의 구성품 중 액상카트리지는 식품첨가물로 사용되는 합성착향료와 유사한 성분으로 구성되어 있어, 이를 합성착향료로 사용하게 되면, 인체에 유해한 니코틴의 잔류 가능성이 존재한다. 따라서 본 연구는 식품첨가물로 사용되고 있는 합성착향료 중 니코틴 검출 분석법을 개발하였다. 분석에 사용된 검체는 시중에 사용되는 합성착향료를 이용하였다. 검체에 증류수와 디클로로메탄을 가하여 산-염기 액-액 추출법을 이용하여 추출 및 정제과정을 거친 후, 이를 질소 농축하고 이동상으로 재용해하여 HPLC/PDA에 주입하였다. 기기분석은 $C_{18}$컬럼을 사용하였고, 20 mM 개미산암모늄 함유 10% 아세토니트릴과 100% 아세토니트릴을 기울기 용리 조건으로 하여 261.9 nm에서 측정하였다. 또한, 액체크로마토그래프-질량분석기를 통해 확인시험을 수행하였으며, 모든 검증은 Codex 가이드라인의 규정에 따라 실시하였다. 그 결과, 니코틴의 정량한계는 0.4 mg/kg 수준이었고, 회수율은 76.40%-96.28%로 나타났다. 또한, 변동계수는 1.74%-5.12%로 Codex 가이드라인 규정에 만족하는 수준이었다. 따라서 개발된 분석법은 식품첨가물에 함유된 니코틴을 분석하기 위한 효율적인 분석법으로 판단된다.

A 13-year-old, spayed, female Chihuahua dog was referred for evaluation of fever, lethargy, and dyspnea. Hematologic evaluation revealed severe neutropenia, thrombocytopenia, and mild anemia. The dog had been undergoing phenobarbital therapy for the past 7 weeks because of generalized seizures due to meningoencephalomyelitis of unknown etiology. After ruling out other possible causes of cytopenias, a tentative diagnosis was made of drug-induced blood cell dyscrasia. The neutropenia and thrombocytopenia resolved after discontinuation of phenobarbital (8 days and 15 days after discontinuation, respectively). This is the first case report in Korea to demonstrate blood dyscrasia associated with idiosyncratic adverse effects of phenobarbital.

The in vitro drug susceptibility of 83 strains of Bordetella bronchiseptica recovered from Korean pigs with atrophic rhinitis was investigated by the use of disk diffusion method. The majority of the organisms were highly resistant in order of prevalence to penicillin(98.7%), ampicillin(91.5%), streptomycin(90.3%), triple sulfa(83.1%), and trimethoprim/sulfamethoxazole(70.7%) while none of them were resistant to gentamicin, only 3.6% to colistin, chloramphenicol and kanamycin and 6.0% to tetracycline. The percentage of the organism resistant to bicozamycin, cephalothin and neomycin were 34.9%, 34.1% and 18.4%, respectively. A high prevalence of multiple drug resistance was observed and the 3 most common resistant patterns among 35 patterns noted were Am Pc Sm Sss Sxt(26.5%), Am Cf Pc Sm Sss Sxt(12.%) and Am Bm Pc Sm Sss Sxt(9.6%) patterns.

Great attention form a public health aspect has centered on the safety of tissues residues of veterinary drugs and environmental contaminants, with intensification of animal husbandry, the use of veterinary drugs will become increasingly important. Heavy responsibility is placed on the veterinarian and livestock producer to observe the period for withdrawal of drug prior to slaughter to assure that illegal concentrations of drug residues in meat, milk and egg do not occur. Every nation has their own regulations in relation to the residues and the guidelines on the use of veterinary drugs to fulfil the regulations, and their own national residue programs to monitoring and eliminate illegal products. Good practice of veterinary drug by users and governmental surveillance programs are very important to ensure animal food safety.

Temporal and subcellular distributions of hyaluronic acid (HA) as a degradable nanoparticle (NP) in animals were investigated to determine if HA-NP could be utilized as an appropriate drug delivery system. After mice were intravenously injected with 5 mg/kg of Cy5.5-labeled HA-NP sized 350-400 nm or larger HA-polymers, the fluorescence intensity was measured in all homogenized organs from 0.5 h to 28 days. HA-NP was greatly detected in spleen, liver and kidney until day 28, while it was maintained at low levels in other organs. HA-polymer was observed at low levels in all organs. HA-NP quantities in spleen and liver were reduced until day 3, but increased sharply between days 3 and 7, then decreased again, while their HA-polymers were maintained at low levels until day 28. In kidneys, both HA-NP and HA-polymer showed high levels after 0.5 h of administration, but steadily decreased until day 28. According to ultrastructural analyses, HA-NP was engulfed in Kupffer cells of liver and macrophages of spleen and kidney at day 1 and was accumulated in the cytoplasm of kidney tubular cells at day 7. Overall, these findings suggest that HA-NP could be considered a desirable drug carrier in the liver, kidney, or spleen.

A study on efficacy and safety of Bio-Gammamix was performed to use for the preventive drug against bacterial diseases to mirror carp(Cyprinus carpio), rainbow trout(Salmo gairdneri), eel(Anguilla japonica) and flounder(Paralichthys olivaceus). The main ingredients of Bio-Gammamix were ferrous fumarate and mixed extrated powders of licorice root, ox bile and garlic. The test drug was proved to improve feeding habit and feed efficiency and decrease cumulative mortality remarkably. After administration, no side effects and histopathological changes were observed. We can prevent outbreaks of bacterial diseases of fish by the dosage of 1kg/ton of fish body weight perorally once or two times in a day for 7 days and Bio-Gammamix is thought to be used effectively an widely against most bacterial fish pathogens.

A 7-year-old spayed female Shih-tzu dog with 4-month history of anorexia and weight loss was diagnosed with splenic hemangiosarcoma. One week after splenectomy, the dog developed severe, multifocal, coalescing erosive and ulcerative dermatosis with epidermal collarettes and crusts on the dorsal trunk. The dog was prescribed systemic antibiotics comprising cephradine and enrofloxacin postoperatively. Histopathological examination of skin biopsies from haired skin lesions revealed changes consistent with pemphigus foliaceus (PF). Tentative diagnosis for this patient was pemphigus-like drug reaction resulting from cephradine treatment. However, given the dog's history of hemangiosarcoma, paraneoplastic pemphigus (PNP), a rarely reported cancer-related pemphigus in dogs, was also considered for tentative diagnosis. Significant clinical remission of dermal lesions was achieved with four weeks of prednisolone and mycophenolate mofetil (MMF) treatment. Drugs were gradually tapered and eventually discontinued with concurrent reduction of dermal lesions, and no further recurrence was noted.
