The purpose of this study was to compare Black-pigmented Bacteroides isolated from necrotic pulp with the presence or absence of eight symptoms associated with pulpal necrosis and to identify the proportion of each Black-pigmented Bacteroides species. The canal contents of fourteen traumatically and cariously necrotized teeth were sampled with a special technique and cultured aerobically and anaerobically for growth in blood agar plate and for Black-pigmented Bacteroides on selective blood agar plate. Each Black-pigmented Bacteroides species were identified by Gram's stain, hemolysis reaction, colony color and morphology and biochemical tests. The results were as follows; 1. 60.9 percent of the bacteria isolated were anaerobic and 39.1 percent were aerobic. 2. Four Black-pigmented Bacteroides species were isolated; B. loescheii (74.1%), B. denticola (11.1%), B. intermedius (7.4%) and B. gingivalis (7.4%). 3. Black-pigmented Bacteroides was found to be significantly related to sinus tract formation and exudate.

In the present studies, samples of blood were taken from 24 Holstein cattle over 2 years old. By using the angled tube method the normal ESR values were determined in cattle under various diseases. The results obtained were summarized as follows ; The standardized ESR/hr using 45$^{\circ}$ angled capillary tubes were 19.0% in case of necrotic mastitis, 23.0% in nephritis, 12.2% in anemia and 4.2% in diarrhea. And the ESR was increased from some necrotic disease, decreased from diarrhea conditions and general the normal ESRs were shown in the sub-clinical or recovery stage of infections or disorders.

Incidence of foot disease of Korean native cattle (231 cases) and Holstein (310 cases) in slaughter house was observed from July August, 1984. 1. Incidence rate of foot disease was 9.09%, 12.90% and 11.27% for Korean native cattle, Holstein and total respectively. 2. Chronic necrotic pododermatitis showed the highest incidence among all foot disease and it's incidence rate was 6.47% in all cattle observes. 3. Topographical incidence rate of chronic necrotic pododermatitis was 25.7%, 60.0% and 14.3% for forefoot, hind foot and not specified respectively, so the disease showed high incidence rate in hind foot.

A case of Burkitt lymphoma diagnosed through fine needle aspiration cytology is described, A 66-year-old man presented with lymphadenopathy on the right cervical neck and axillary area. An ultrasonogram and CT scan for the cervical neck showed a multiple variable sized lymphadenopathy with pericapsular invasion and necrotic foci, Fine needle aspiration cytology (FNAC) of the cervical lymph nodes revealed very cellular and necrotic smears consisting of diffusely scattered intermediate monotonous round cells, tingible body macrophages and many mitotic figures. Histological features of the excised lymph nodes showed the classic morphological features of Burkitt lymphoma. Recognition of the characteristic cytological features can suggest the possibility of Burkitt lymphoma.

In the infected immature tooth with periapical involvement, the pulp is considered to hardly exist in the canal and periapical area. Such a tooth receives apexification procedure, because revascularization of the pulp chamber is in principle not expected. Apexification is beneficial to induce further development of an apex to close the foramina, but does not promote the thickness of the entire canal wall dentin. It may be possible for the pulp to be only partially necrotic and infected when an extremely large communication from the pulp space to the periapical tissues exists with a very young tooth. If this were the case, vital pulp in the apical part of the canal could proliferate new pulp into the coronal pulp space by the successful removal and disinfection of the necrotic infected coronal pulp.(omitted)

Regenerative endodontics has a potential to heal a partially necrotic pulp, which can be beneficial for the continued root development and strengthening of immature teeth. For this purpose, triple antibiotic mixture of ciprofloxacin, metronidazole, and minocycline was recommended as intracanal medicament in an attempt to disinfect the root canal system for revascularization of a tooth with a necrotic pulp. However, discoloration of the tooth was reported after applying this. This case shows the idea for preventing the tooth discoloration using a delivery syringe to avoid the contact between the clinical crown and the antibiotics.

The mitochondrial targeting domain (MTD) of Noxa contributes to its mitochondrial localization and to apoptosis induction. As a peptide, MTD fused with octa-arginine (R8), a CPP, induces necrosis related to intracellular calcium influx and destruction of mitochondria and endoplasmic reticulum. We searched for homologs of MTD, and compared their cell killing capability when fused with R8. Three of the seven peptides triggered cell death with similar mechanisms. The comparative analysis of peptide sequences showed that four amino acid sites of MTD are critical in regulating necrosis, suggesting the potential to generate artificial, adjustable cytotoxic peptides, which could be effective medicines for many diseases. Thus, homologs functionality could hint to the functions of their belonging proteins.

Natural virus infection of cultivated Daphe odora plants showing chlorosis and stunting was observed and their causal agent was investigated. An isolate of isometic virus was purified from infected leaf tissues, and it could infect systemic severe mosaic on Chenopodium quinoa and C. amaranticolor. cDNA library was generated from partially purified viral RNAs and oligo dT primer-pSPORTl system, and recombinant clones were selected and their inserts were sequenced randomly. Nucleotide sequences of the virus were analyzed by BLAST, and it was closely related to members of subgroup B in the genus Nepovirus. The sequence analysis suggest that the virus was identified as an isolate of Cycas necrotic stunt virus (CNSV) because it was 89.7 ％ and 94.7 ％ identical to known CNSV for the CP and 3' noncoding region, respecitively. RT-PCR was performed to screen disease incidence of CNSV in Daphe plants, and five out of 10 plants (50 ％) were infected by CNSV This is the first sequence information of CNSV from Daphe plants.

Chinese yam(D. opposita Thunb. cv. Jang-Ma) plants showing necrotic mosaic symptom were collected from their growing fields in Andong, Korea. Electron microscoptic examination of negatively stained preparations showed filamentous particles of 660nm in length. The virues purified partially were used to isolate Viral RNA as template for RT-PCR to amplify the CP gene with ChYNMV specific and oligo dT primers. Amino acids sequeces revealed that the viruses shared 99.3％ similarity with ChYNMV(AB044386) which was known as the member of macluravirus. So the viruses from Chinese yam(D. opposita Thunb. cv. Jang-Ma) plants were identified as ChYNMV. Comparing the amino aced sequences of ChYNMV strains with other macluraviruses such as CdMV, NLV and MacMV revealed that N-terminal was the most variable region and conserved regions were present within the genus Macluravirus.
