Congenital anomalies occur at low levels in Korean antive cattle. PCR and Serum neutrlizing test against BVD, Akabane virus, Ibaraki virus, Kasba virus were examined. The results were all negative. Gross anatomical analysis was carried aout. Congenital abnormal newborn calf had 2 atropic left hindlimbs, which was nor moved autonomosly. The length of 2 atropic hindlimbs was 72 em and 48cm respectively. Both of them were curved severely at joints. Affected limbs were developed in connective tissue but lack of muscular tissue. In the abdominal region right kidney was normal. But there were two left kidneys which was half size compared with normal kidney. One of them had polycysts. In skeletal region, affected left limb is defective of head of femur and tibia.

An 11-year-old intact male mixed-breed dog was referred for evaluation of a splenic mass. On radiographs, the cardiac apex, stomach, and head of the spleen were on the right and the descending colon was on the left of the midline. In addition, the left kidney was located more cranially than the right kidney. Standard two-dimensional echocardiographic images were obtained from each inverted left and right parasternal windows. Furthermore, the spleen was observed on the right side and a splenic mass was found on the splenic tail. Based on the radiographic and ultrasonographic characteristics of the patient, a diagnosis of situs inversus totalis (SIT) and a splenic mass was made, and splenic resection was performed successfully with no unexpected complications. The splenic mass was confirmed histopathologically as being marginal zone lymphoma (MZL). This report describes a dog with SIT and splenic MZL.

Histopathological studies on the two lymphomyeloid organs of spleen and head kidney in tilapia, Oreochromis niloticus, were carried out to clarify the significance on the morphological characteristics of melano - macrophage centers (MMCs) which are varied in different physiological and pathological conditions of teleosts. To examine the histological changes by the artificial modification of the immunological states, tilapia were treated intraperitoneally with FKC and LPS of Edwardsiella tarda, and orally with dexamethasone, and then followed by the intraperitoneal injection of colloidal carbon for chasing the macrophages. There were marked differences in phagocytic avidity of macrophages, and accumulating patterns of carbon - ladening macrophages into the MMCs among the test groups. In the non - pretreated control group, carbon - ladening macrophages were densely accumulated at 12th and 20th day within the MMCs of head kidney and spleen, respectively. And, in the groups treated with bacterial antigens (FKC & LPS), the macrophages were more rapidly and densely aggregated within MMCs. But in the group with dexamethasone, only a few carbon particles were detected in both organs. Any compactly isolated form of particles was not found in this group. From the present results, it was strongly suggested that certain changes in immunological states of tilapia influence on the morphology of MMCs including the frequency of appearance, sizes, aggregating patterns or outlines. Therefore, morphology of MMCs would be very important in the interpretation for histopathological findings seen in the teleost's lymphomyeloid organs.

The author experienced a case of $Henoch-Sch\"{o}nlein$ purpura with epididymitis in a 6-year-old boy who was admitted to our hospital due to left scrotal pain and the relapse of purpura on lower extremities for 3 days. Scrotal ultrasonography on admission revealed homogenously enlarged left epididymal head and small amount of fluid collection in left tunical space. The size of left epididymal head decreased gradually with no more evidence of fluid collection on day 7 and recovered completely on day 21. The author reports a case of $Henoch-Sch\"{o}nlein$ purpura with epididymitis with brief review of related literatures.

Metastatic carcinomas to the thyroid gland are rare, and thyroid involvement by secondary carcinomas commonly results from direct the extension of malignant cells from adjacent organs such as the larynx or the trachea. The common primary sites of thyroid metastasis are kidney, breast, lung, and lymphoid tissue. Among head and neck cancers, nasopharyngeal carcinoma has a relatively high incidence of distant metastases to other sites and commonly involving sites are bone, lung, and liver. Recently, we experienced a case of a 43-year-old male who had been presented with neck mass for 3 months. He was diagnosed non-keratinizing nasopharyngeal carcinoma in 1993. And, thyroid metastasis of nasopharyngeal carcinoma was confirmed by total thyroidectomy. So we report this rare case with the review of literatures.

The goal of this study is to develop a biomarker used in monitoring abnormal behaviors of Japanese medaka (Oryzias latipes) as a model organism caused by hazardous chemicals. Japanese medaka was treated by copper of appropriate sublethal concentrations after starvation for 48 hr. The untreated individuals showed common behavioral characteristics (i.e. , smooth and linear movements). Locomotive activity of the fish was monitored using an image processing and automatic data acquisition system. When treated with copper (100 ppb), the fish showed shaking patterns more frequently. As the concentration of copper increased to 1,000 ppb, activity decreated, and the fish showed an erratic movement. Fish were exposed to copper at various concentrations (0,100 and 1,000 ppb) for 24 hrs, and acetylcholine esterase (AChE) activity was observed. When fish were exposed to 1,000 ppb of copper, the body AChE activities appeared to decrease but the head AChE activities showed little change. Expressions of tyrosine hydroxylase (TH) protein in the different organs from both head (brain) and body (kidney) portions affected by the copper treatment were analyzed using immunohistochemical technique compared with control. Five organs of the fish (olfactory bulb, hyothalamus, optic lobe, pons and myelencephalon regions) showed a relatively strong TH protein expression in the control experiment. A differential expression of TH, however, was observed in the treatment (100 ppb and 1,000 ppb). The treatment (1,000 ppb) significantly suppressed TH protein production in the brain regions. In kidney, however, the same treatment caused little suppression compared with the control. Copper appeared to be less effective in suppression of TH than diazinon, a known TH suppressor. It was concluded that TH could be used at a potential biomarker to monitor the acute copper toxicity in Japanese medaka.

Interleukin-2 enhancer binding factor 2 (ILF2) was reported to regulate transcription of interleukin-2 (IL-2), a central cytokine in the regulation of T-cell responses. This property of ILF2 was well characterized in human and mammals, but little is known in bony fish. In this paper, an ILF2 homologue was cloned and well characterized from Tetraodon nigrovirid is for the further investigation of the function of ILF2 in bony fish. The full-length Tetraodon ILF2 cDNA was 1380 bp in size and contained an open reading frame (ORF) of 1164 bp that translates into a 387 amino-acid peptide with a molecular weight of 42.9 kDa, a 5' untranslated region (UTR) of 57 bp, and a 3' UTR of 159 bp containing a poly A tail. The deduced peptide of Tetraodon ILF2 shared an overall identity of 58%~93% with other known ILF2 sequences, and contained two N-glycosylation sites, two N-myristoylation sites, one RGD cell attachment sequence, six protein kinase C phosphorylation sites, one amino-terminal RGG-rich single-stranded RNA-binding domain, and a DZF zinc-finger nucleic acid binding domain, most of which were highly conserved through species compared. Constitutive expression of Tetraodon ILF2 was observed in all tissues examined, including gill, gut, head kidney, spleen, liver, brain and heart. The highest expression was detected in heart, followed by liver, head kidney and brain. Stimulation with LPS did not significantly alter the expression of Tetraodon ILF2. Gene organization analysis showed that the Tetraodon ILF2 gene have fifteen exons, one more than other known ILF2 genes in human and mouse. Genes up- and down-stream from the Tetraodon ILF2 were Rpa12, Peroxin-11b, Smad4, Snapap and Txnip homologue, which were different from that in human and mouse.

Interferons are kinds of cytokines that play an important role in antiviral defense mechanisms during viral infection by converting cells to synthesize proteins that inhibit viral replication. In the present study, an antiviral response against Spring viremia of carp virus (SVCV) was developed in common carp, Cyprinus carpio following stimulation with the potent interferon inducer, poly inosinic : cytidylic acid (poly I:C). Poly I:C injected fish showed lower cumulative mortalities against SVCV than untreated fish did. Moreover, in vitro study showed that head kidney leucocytes (HKLs) produced an interferon-like cytokine (ILC) after stimulation with poly I:C. According cytopathic effect reduction (CPER) assay to examine antiviral activity of crude ILC, the capacity of HKLs for ILC production was highest at 1×$10^6$cells/ml and significantly enhanced when treated with 20~50$\mu{g}$/ml of poly I:C. The optimal temperature and concentration of FBS to induce the highest ILC production were $20^\circ{C}$ and 5%, respectively.
