A 5-year-old neutered female Dachshund dog presented with a 3-month history of hyperthermia, skin lesions, and shifting lameness. Based on physical examination, blood tests, urinalysis, and radiographs, the dog was diagnosed with systemic lupus erythematosus. Clinical signs improved after administration of prednisolone and cyclosporine but relapsed after the prednisolone was reduced due to side effects. Oral levamisole was commenced and the other immunosuppressants were tapered over a period of 2 months and then stopped. Levamisole was retained as the sole therapy for an additional 2 months. Six months after discontinuation of all treatment, the patient remained in remission.

The purpose of this study is to evaluate an effect of levamisole on the chemical crcinogenesis in the submandibular salivary gland of rats through histopathologic observation. 60 male Sprague Dawley rats were employed in this study, divided into one control and two experimental groups. An pellet of 5 mg of 9, 10-dimethyl-1,2-benzathracene(DMBA) powder was implanted into submandibular salivary gland of each animal among 20 in control. And each animal among 20 in experimental group 1 received 0.7 mg of levamisole hydrochloride orally every day starting at the beginning of the fifth week after DMBA implantation under the same methods as in control. And each animal among 20 in experimental group 2 received the same treatment as in control at the beginning of the fifth week after oral administration of levamisole hydrochloride under the same method as experimental group 1. Each 5 animals in control at the end of 2nd, 4th, 6th 8th, week after experiments, and each 10 animals in experimental group 1,2 at the end of 6th, 8th week after experiments were sacrificed at random. Also the specimens from experimental sites of submandibular salivary glands were routinely processed for histopathologic observation under Hematoxilin-eosin(H-E) staining. The obtained results were as follows : 1. In control, generally, the glandular ductal cell showed the tendency of dysplasia or malignancy with progression of experiment. 2. In experimental group 1, generally, the dysplasia or malignancy of the glandular ductal cell was less prominent than in control, while the lymphocyte infiltration and fibrosis were prominent. 3. In experimental group 2, generally, the dysplasia of the glandular ductal cell was significantly less prominent than in control, while the fibrosis was prominent. 4. Under above results levamisole was thought to delay or prevent the chemical carcinogenesis in the submandibular salivary gland.

In this study, the immunomodulating effects of levamisole, selenium and tocopherol on blood neutrophils and peritoneal macrophages of goat were evaluated in vitro and in vivo. The functions of blood neutrophils and peritoneal macrophages were assayed by random and direct migration, phagocytosis of S aureus, production of superoxide and hydrogen peroxide. The results obtained were summarized as follows: In vitro trials 1. Levamisole treatment enhanced the random and direct migration of goat blood neutrophils when compared with untreated cell, and a significant (p<0.01) enhancement was noticed at the concentration of $100{\mu}g$ for direct migration and $50{\mu}g{\sim}1,000{\mu}g\;per\;ml$ of culture medium for random migration. There was no influence of selenium and tocopherol on random and direct migration of neutrophil at all of treatment concentration. 2. Neutrophils produced higher levels of superoxide by lcvamisole treatment at the concentration of $100{\mu}g$ and by selenium treatment at the concentration of $1.0{\mu}g$, but the production of hydrogen peroxide was not increased. Tocopherol had no effect on the production of antimicrobicidal oxygen metabolites of neutrophils at various concentrations. 3. No differences of phagocytic activity were observed when neutrophils were treated with three substances. In vivo trials 1. Blood neutrophils of goats orally administered levaraisole showed significantly (p<0.05) higher random migration from 2 to 24 hours after feeding (2.5mg/kg of body weight). Augmentation of random migration of neutrophil from goats orally administered selenium-tocopherol mixture (selenium $100{\mu}g$-tocopherol 200IU/head/day) was observed at 10 days and the significant (p<0.05) increase was shown from 30 days after feeding and continued throughout the feeding periods. 2. There was no effect on phagocytic activity and production of antimicrobicidal oxygen metabolites of neutrophils from goats administered levamisole or selenium-tocopherol mixture. 3. Random migration, production of superoxide and hydrogen peroxide and S aureus phagocytic activity of peritoneal macrophages of goats administered 300ml of levamisole-thioglycollatc medium mixture $(2.5{\mu}g/ml)$ into peritoneal cavity increased significantly (p<0.01 or p<0.05) when compared with those of goats administered thioglycollate medium alone.

A total of 127 foremilk samples from dairy farms in Chonnam district was examined for the subclinical mastitis eve. six months, using a method of the N-acetyl-${\beta}$ -D-glucosaminidase (NAGase) test in relation to the California mastitis test(CMT) and the somatic tell count(SCC) and the compatibility and efficiency rating between the NAGase test and the other screening test were conducted. Fifteen subclinically mastitic cows were treated with a single oral dose of 7.5mg/kg of levamisole hydrochloride. The results are summarized as follows. 1. A linear relationship was found among the NAGase level, the CMT score and the SCC level, and it was found that NAGase activity measurements were comparable with other screening tests for diagnosing cows with mastitis. 2. Compatibilites between the NAGase and the CMT were 96.1%, and that of the NAGase and SCC were 93.7%. On the other hand, relative efficiency ratings of Postle's equation between the NAGase and CMT were 89.4%, and that of the NAGase and SCC were 84.1%. 3. Considering the result of CMT, SCC and NAGase level after treatment with levamisole hydrochloride it seemed to be of special value in the treatment of bovine subclinical mastitis.

Purpose: Steroid dependent nephrotic syndrome (SDNS) is a chronic illness in childhood hard to treat. Steroid sparing drugs are often used, because long-term steroid therapy can cause severe side effects. We studied to compare efficacy between MMF and other drugs including cyclosporine and levamisole. Methods: This study was performed retrospectively on patients with SDNS, who were treated at Pusan National University Children's hospital. MMF group included 11 patients who were treated with MMF for at least six months between June 2012 and July 2014. As control groups, cyclosporine group (n=15) and levamisole group (n=18) included patients treated between January 2008 and July 2014. Number of relapse was analyzed in patients treated more than six months, and relapse free for one year was analyzed in patients treated more than one year. Results: In MMF group, ten were boys and mean age at onset was 5.8 years. Mean age at starting of MMF was 8.6 years. Number of relapse in MMF group was reduced significantly after treatment from 3.4 /year to 0.2 /year (P=0.003). There was no significant difference in number of relapse among groups (MMF: 0.2 /year, cyclosporine: 0.5 /year, levamisole: 0.5 /year). Comparing the early relapse within six months after treatment levamisole group was significantly higher than the other two groups (P=0.04). Conclusions: MMF which is used in SDNS significantly reduced the relapse and side effects were rare. In addition, MMF did not show any significant difference in comparison with the other two groups in number of relapse and relapse free for one year.

Levamisloe(LMS)이 뱀장어의 면역반응에 미치는 영향을 측정하기 위해서 뱀장어의 혈액 및 신장으로부터 백혈구를 분리하여, 림프구의 증식능, MIF 생산능, 자연살해세포활성능, 탐식세포의 탐식능, superoxide anion, hydrogen peroxide 및 lysozyme 활성능 등을 측정하였다. LMS는 T-cell 마이토젠인 Con A 및 PHA 처리시에는 LMS 농도에 비례감소를 보인 반면에 B-cell 마이토젠인 LPS에는 LMS 처리와는 무관하게 큰 차이를 보이지 않았다. 한편 MIF 및 MAF의 생성에는 LMS 처리 농도에 비례 증가되었다. NK 세포의 활성은 LMS 첨가농도에 비례 증가하였는데, 이는 표적세포에 대한 결합율을 증가시킨 결과 NK 세포의 활성이 증가된 것으로 보인다. LMS는 백혈구의 탐식능, superoxide anion의 생성능, hydrogen peroxide 생성능 및 Iysozyme의 활성을 증가시켰다. 이러한 결과로부터 LMS가 어체의 면역작용에 관여하는 작용기전은 면역 작동세포수의 증가를 촉진시키기보다는 분화를 촉진시켜서 cytokine의 방출증가 및 세포의 기능활성을 증강시킴을 알수 있다.

닭의 전염성 F낭병 바이러스(IBDV)가 원인 바이러스인 전염성 F낭병은 전 세계 양계산업에 경제적으로 피해가 큰 중요한 질병이다. 이 연구의 목적은 닭에서 IBDV에 대한 방어면역을 유도하기 위한 in ovo 초회항원자극(priming)과 불활화백신에 의한 보강접종 방법에 항원보강제(adjuvant)로 chicken interleukin 6 (pcDNA-ChIL-6;plasmid encoding chicken interleukin-6)와 levamisole (LMS)의 효과를 조사하는 것이다. IBDV의 VP2, VP, VP3 protein을 암호화하는 유전자백신인 plasmid DNA vaccine (pcDNA-VP243) 단독 또는 pcDNA-ChIL-6 또는 LMS와 함께 18일령 부화란의 양막낭(amniotic sac)에 접종하고 부화한 1주령의 병아리에 불활화 IBD 백신을 근육 접종한 다음 3주령에 고병원성 IBDV인 SH/92 주로 공격 접종하고 10일 동안 관찰하였다. 백신하지 않은 공격접종 대조군이 100%의 폐사율을 보인 반면 pcDNA-VP243 단독 접종군과 pcDNA-VP243에 pcDNA-ChIL-6 또는 LMS를 첨가한 실험군은 모두 100%의 생존율을 나타내었다. 그러나 공격접종 후 F낭의 손상을 평가하기 위한 IBDV RNA의 검출, B/B ratio와 F낭의 병변지수(lesion score) 등을 분석한 결과 pcDNA-VP243에 pcDNA-ChIL-6 또는 LMS를 첨가한 실험군은 pcDNA-VP243 단독 접종군보다 향상된 방어효과를 나타내지 않았다. 이 실험결과는 유전자백신에 의한 in ovo 초회항원자극-불활화백신에 의한 보강접종법이 고병원성 IBDV로부터 닭을 보호하기 위한 효과적인 방법이었으나 pcDNA-ChIL-6 또는 LMS의 첨가로 인한 방어효과의 향상은 나타나지 않았다.
