  • The effect of Cimicifuga heracleifolia on CC1$_4$-induced hepatotoxicity was investigated. Cimicifuga heracleifolia has been used to diaphoresis, antipyretics and detoxification in oriental remedy. We examined the effect of Cimicifuga heracleifolia methanol extract by blood chemical analysis and histopathologic examination. ALT and AST were decreased by 38% and 67% in pretreatment group of Cimicifuga heracleifolia compared to CC1$_4$control group respectively. There were significant changes neither in total protein, albumin, triglyceride and cholesterol nor in BUN and creatinine. In histopathologic examination, there were severe necrosis and hemorrhage with infiltration of inflammatory cells around the central vein, zone 3 in the liver of CC1$_4$ treated rat. Ballooning degeneration of hepatocytes were frequently noted in the periphery of the hemorrhagic necrosis. In Cimicifuga heracleifolia pretreatment group, we observed mild degree of ballooning degeneration and inflammatory cell infiltration. No gross necrosis was observed. We measured malondialdehyde (MDA) formation by TBA method. It showed that the formation of MDA in Cimicifuga heracleifolia pretreatment group was decreased compared to the $CCl_4$control group. We got the result of the effect of Cimicifuga heracleifolia on CC1$_4$-induced hepatotoxicity by decreasing serum ALT and AST. It seems that the decrease of lipid peroxidation is related to the recovery effect.

  • Alcoholic liver disease (ALD), which encompasses alcoholic steatosis, alcoholic hepatitis, and alcoholic cirrhosis, is a major cause of morbidity and mortality worldwide. Although the economic and health impacts of ALD are clear, few advances have been made in its prevention or treatment. We recently demonstrated that the insect-derived antimicrobial peptide CopA3 exerts anti-apoptotic and anti-inflammatory activities in various cell systems, including neuronal cells and colonic epithelial cells. Here, we tested whether CopA3 inhibits ethanol-induced liver injury in mice. Mice were intraperitoneally injected with ethanol only or ethanol plus CopA3 for 24 h and then liver injury and inflammatory responses were measured. Ethanol enhanced the production of proinflammatory cytokines, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, interferon (IFN)-γ, and IL-10. It also induced hepatocyte apoptosis and ballooning degeneration in hepatocytes. Notably, all these effects were eliminated or significantly reduced by CopA3 treatment. Collectively, our findings demonstrate that CopA3 ameliorates ethanol-induced liver cell damage and inflammation, suggesting the therapeutic potential of CopA3 for treating ethanol-induced liver injury.

  • An aqueous extract of oriental herbal composition named Onchengyeum and curcumin, an antioxidant isolated from turmeric (Curcuma Zonga L.) reduced hepatotoxicity induced by carbon tetrachloride ($CCI_4$). Improved liver function was observed by measuring the activities of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), blood urea nitrogen (BUN), creatinine (CRE), total cholesterol (T-CHO), triglyceride (TG), low density lipoprotein cholesterol (LDL-CHO), high density lipoprotein cholesterol (HDL-CHO), total protein (TP), albumin (ALB) and total bilirubin (BIL) in serum. Hepatic parameters monitored were levels of cholesterol (CHO), triglyceride (TG), and malondialdehyde (MDA) and activities of cytochrome P450 (CYP), NADPH-CYP reductase, superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione S-transferase (GST), glutathione reductase (GR), and glutathione peroxidase (GPx). The histopathological examination showed that the treatment of Onchengyeum and curcumin relieved the ballooning degeneration of hepatocytes which had been generated by $CCI_4$. The results suggested that hepatoprotective effects of Onchengyeum and curcumin possibly are due to their promising antioxidative activity.

  • A dead dove was found on the road and submitted for diagnosis. The bird was severely emaciated, with deformation in its facial area. Grossly, white coalescing nodules were seen on the cut surface of the nasal cavity. Histopathologically, epithelial cells of the upper respiratory tract were markedly proliferated, with ballooning degeneration, down growth of the rete ridge, and large eosinophilic intracytoplasmic inclusion bodies. Parakeratotic hyperkeratosis and focal necrotic focus was present in the proliferative area. The facial bones showed partial bone resorption. Transmission electron microscopy revealed numerous viral particles in epithelial cells with dumbbell-shaped bodies, consistent with poxvirus.

  • Three neonatal pigs from the same litter in a domestic farm were born with skin lesions. Grossly, multiple well-circumscribed, round papules distributed over the skin of the three piglets. Two piglets were submitted for a diagnosis of skin disease. Microscopically, epidermal hyperplasia with ballooning degeneration of stratum spinosum keratinocytes was observed. Some keratinocytes contained eosinophilic intracytoplasmic inclusions and a central nuclear vacuole and chromatin margination. Swinepox (SWP) virus was detected by polymerase chain reaction and nucleotide sequencing, and Staphylococcus hyicus was isolated in skin lesions. Based on the gross findings and laboratory results, these piglets were diagnosed with congenital SWP with a secondary staphylococcal infection.

  • This study was carried out to investigate the types and frequency of abnormal stomata in Crassulaceae. We observed the surface of the leaves on twenty four species involved five varieties belonging to eight genera of Crassulaceae. Nineteen types of abnormal stomata were found in the families. Among them three types such as the single guard cell, the aborted stomata, and the single-aborted guard cell were highly observed from nineteen to twenty four species, and two types of the overlapped-thickening guard cells and the arrested stomata exhibited commonly from seven to thirteen species. The another types of them rarely occurred from one to five species. Most of abnormal stomata were found in S. alboroseum, P. chinense and S. sarmentosum, and a few types of them were observed in the other species. The three types of the ballooning guard cells, the cross cleaved stomata, and the fused pore stomata were first reported here in the seed plants. It was thought that the abnormal stomata were formed by the result of degeneration and abnormal development of normal stomata.

  • Porcine juvenile pustular psoriasiform dermatitis (PJPPD) is a disease of young pigs and characterized by nonpruritic round eruption of skin. The cause of this disease is yet undetermined but is presumed to be genetic predisposition. There may be few opportunities for veterinarian to detect this disease compared with actual situation in field because these lesions resolve spontaneously in two months. The authors detected spontaneous PJPPD case and performed clinical and pathological studies on three pigs from one farm. The specific skin lesions were observed in the forty-day old pigs of mixed breed, which were produced by the sows received semen from the same boar, restrictively. However, there was no skin lesion of pigs in suckling or fattening periods. Grossly, lesions were commonly found on the ventral abdominal part as a papule and were spreaded to the skin of whole body. With the spreading of lesions centrifugally, skin was showed as a umbilicated plaques or mosaic pattern with a few pustules or crusts. Microscopically, the most prominent lesion was the psoriasiform hyperplasia with acanthosis, down growth of rete ridges, exocytosis of eosinophils and neutrophils, ballooning degeneration of superficial epidermis, and koilocytic degeneration of keratinocytes. Additionally, there were moderate dermal edema and severe mixed cellular infiltration, especially eosinophils. No infectious agent which can cause the skin lesion, was detected or cultured, and no lesion caused by infectious agents was also observed, pathologically. With pathological results of this study, it is supposed that pathogenesis or severity of PJPPD may be related to the infiltration of eosinophil or hypersensitivity.

  • The purpose of this study was to examine the antiobesity effects of lactic acid bacteria-fermented Dioscoreae Rhizoma powder (LDR) in Sprague-Dawley rats with high-fat diet (HFD)-induced obesity. Rats were divided into 5 groups: normal diet group, control (high fat diet-vehicle) group, 0.4 g/kg LDR (high fat diet + 0.4 g/kg lactic acid bacteria-fermented Dioscoreae Rhizoma powder) group, 1 g/kg LDR (high fat diet + lactic acid bacteria-fermented Dioscoreae Rhizoma powder) group, 2.5g/kg LDR (high fat diet + lactic acid bacteria-fermented Dioscoreae Rhizoma powder) group. Our results indicate that LDR administration has effects on decreasing of body weight, fat weight, blood parameters and adipocyte size in the obesity animals. In addition, verified that fat degeneration and ballooning degeneration were alleviated in the experimental group fed on a high fat diet combined with LDR groups. These results indicate that lactic acid bacteria-fermented Dioscoreae Rhizoma powder may reduce elevating body weight and lipid accumulation in rat fed a high fat diet, suggesting its usefulness as a functional food for reducing body fat and obesity.

  • The protective effect of SAPP, an extract from a novel herbal complex, on acute liver injury was investigated using mouse animal model in this study. The content of total phenol in SAPP was increased at dose dependent manner. Consistent with the content of total phenol, SAPP showed the significant anti-oxidative effects on 1, 1-diphenyl-2-picrylhydrazyl (DPPH) method. Acute liver injury was induced by D-galactosamine (D-GalN) in mouse. Treatment with SAPP significantly reduced the level of alanine transaminase (ALT) and aspartate transaminase (AST) in serum. Histological observation revealed that whereas D-GalN treated mouse showed vacuolization of hepatocytes, sinusoidal dilation and congestion, loss of cell boundaries and ballooning degeneration, loss of architecture and cell necrosis, treatment with SAPP improved D-GalN-induced liver injury. These results suggest that SAPP shows protective effects against D-GalN-induced hepatotoxicity in vivo acute mouse model.
