The present studs was undertaken to observe the histopathological changes on the cardiac and skeletal muscles, and liver of rabbits fed a commercial ration, either alone or with supplements of Zinc (3,000mg/kg. of diet, as sulfate), Copper (1,500mg/kg. of diet, as sulfate), Linoleic acid (3% of diet), Zinc with Linoleic acid and Copper with Linoleic acid. In the skeletal muscle, light microscopic changes observed were cloudy swelling, hyaline degeneration, atrophy, fragmentation and coagulative necrosis of muscle fibers, and proliferation of fibroblasts and infiltration of mononuclear cells. Especially, in rabbits fed with supplements of Zinc with Linoleic acid and Copper with Linoleic acid, calcification with muscle fibers progressing to necrosis were often observed. In the myocardium, loss of muscle fibers with necrosis and vacuolization, hyaline degeneration, hemorrhage and congestion were observed. In the liver, congestion and necrosis of hepatocytes, and centrilobular necrosis were observed. Differences of histological changes among the experimental groups was not marked.

To determine the effect of Korean medicine treatment of avascular necrosis of the femoral head (ANFH) this study reviewed both single ingredients and bioactive compounds in the treatment of ANFH in a rat model. Literature was retrieved from PubMed and Google Scholar using the keywords "femur head necrosis," "natural extract," and "rat." The data from studies analyzed included: rats' characteristics, development methods of ANFH, natural extracts administration, observation methods, and outcome indicators. Two independent researchers screened all articles retrieved and 26 studies were chosen. The most used rat species was the Sprague Dawley rat (76.9%). To induce ANFH, steroid injections (46.2%), and oral gavage (53.8%) were typically used. Studies focused mainly on factors affecting bone formation (65.3%), and apoptosis (53.8%). Research on ANFH focused on using traditional natural substances mentioned in classical literature to confirm its effectiveness against anti-inflammation, osteogenesis, and cell death. ANFH has a diverse etiology, therefore research models such as genetic analysis of human-derived samples from ANFH patients may shed more light on the condition. Moreover, research into herbal medicines and pharmacoacupuncture treatment of ANFH should precede.

Infectious hematopoietic necrosis virus (IHNV) is s significant viral pathogen affecting cultured rainbow trout (Oncorhynchus mykiss) in Korea. In this study, five monoclonal antibodies (mAbs) (IHNV-1, 2, 3, 4, and 5) were produced using purified IHNV. Reactivities of these mAbs were analyzed by western blot (WB), enzyme-linked immunosorbent assay (ELISA), and indirect fluorescent antibody test (IFAT). These mAbs recognized glycoprotein (69 kDa, IHNV-1), nucleocapsid protein (39 kDa, IHNV-3, 4, and 5), or phosphoprotein (27 kDa, IHNV-2) of IHNV by WB analysis. ELISA results indicated that these five mAbs were specific to IHNV without showing any cross-reactivity against other fish viruses (hirame rhabdovirus, infectious pancreatic necrosis virus, and viral hemorrhagic septicemia virus). IFAT demonstrated specific fluorescence signals of IHNV-infected epithelioma papulosum cyprini (EPC) cells, whereas no reactivity of normal EPC cells was observed. These mAbs can be very useful for immuno-diagnosis of IHNV infection.

We herein present the unique case of a 68-year-old male diabetic patient who developed sterile necrosis of the sternum 1 month after myocardial revascularization with the use of bilateral internal thoracic artery grafts. The sternum had been closed by the bilateral Robicsek wiring technique. The sternum was removed, and bilateral pectoralis major flaps were used to cover the defect. The patient had an uneventful recovery.

This experiment was done to set up the immunohistochemical detection method for infectious hematopoietic necrosis virus(IHNV) antigens in the monolayers of CHSE-214 cell cultures inoculated with IHNV. Specific identification of IHNV antigens was detected in the cytoplasms of infected cells by the use of monoclonal antibodies to glycoproteins. The specific positive signal was observed as a distinct red color. The result showed that streptavidin alkaline phosphatase immunohistochemistry specifically identified IHNV antigens in infected cultured cells.

Bone scan is a very useful technique for detection of aseptic necrosis and frequently used in the detection of aseptic necrosis of the femoral head. We have used this diagnostic tool in a patient to detect aseptic necrosis of the talus, a common complication resulting from foot injuries.

Although avascular necrosis of the hallucal sesamoid has not been frequently addressed in the literature, it should be considered in the differential diagnosis of persistent forefoot pain. We experienced 3 cases of avascular necrosis of the hallucal sesamoid with sclerosis of the sesamoid bone on radiograghs and computed tomograghy images. T1 and T2-weighted MRI images in 2 patients showed low signal intensity in the sesamoid bone, which suggested osteonecrosis and confirmed by histology. We report 3 cases of avascular necrosis of sesamoid with a review of the literature.

In this study, carp edemavirus disease and herpesviral hematopoietic necrosis were examined in carp (Cyprinus carpio) and crucian carp (Carassius auratus) imported from China. From August 2016 to May 2017, 100 carp and 300 crucian carp were examined. There were no clinical symptoms in all the tested fish, and no internal or external parasitic infections were identified except for the detection of Argulus sp. in one leather carp. Carp edema virus disease was examined by PCR in C. carpio, but all were negative. In C. auratus, herpesviral hematopoietic necrosis was tested by PCR and 4 out of 300 were positive. The results of this study are expected to be useful as basic data for conducting risk analysis on the relevant organisms and counterpart countries or for designating new pathogens for quarantine.

대퇴골두 무혈성괴사에 대해서는 수 많은 연구가 광범위하게 진행되어왔으나 아직 병인과 최선의 치료방법은 모르고 있는 실정이다. 앞으로 더 많은 연구와 분석이 이루어져서 새로운 정보가 추가된다면 이 질환으로 인한 유병율과 이환율을 줄일 수 있을 것이다.

This experiment was carried out to establish the immunohistochemical diagnostic method for infectious pancreatic necrosis in the monolayers of CHSE-214 cell cultures and paraffin-embedded tissue sections from rainbow trout infected with infectious pancreatic necrosis virus(IPNV). Specific identification of IPNV antigens was often demonstrated in the pancreatic exocrine cells, and less in the intestinal mucous epithelia and the renal hemopoietic tissues by the use of monoclonal antibodies against capsid protein VP2. The specific reaction was seen as a distinct red cytoplasmic color, often as small granules of various sizes. The result showed that streptavidin alkaline phosphatase immunohistochemisry specifically identified IPNV antigens in both infected cell cultures and tissue sections.
