Abstract
Orchidaceae (with >28,000 orchid species) are one of the two largest plant families, with economically and ecologically important species, and occupy global and diverse niches with primary distribution in rainforests. Among orchids, 70% grow on other plants as epiphytes; epiphytes contribute up to ~50% of the plant diversity in rainforests and provide food and shelter for diverse animals and microbes, thereby contributing to the health of these ecosystems. Orchids account for over two-thirds of vascular epiphytes and provide an excellent model for studying evolution of epiphytism. Extensive phylogenetic studies of Orchidaceae and subgroups have ;been crucial for understanding relationships among many orchid lineages, although some uncertainties remain. For example, in the largest subfamily Epidendroideae with nearly all epiphytic orchids, relationships among some tribes and many subtribes are still controversial, hampering evolutionary analyses of epiphytism. Here we obtained 1,450 low-copy nuclear genes from 610 orchid species, including 431 with newly generated transcriptomes, and used them for the reconstruction of robust Orchidaceae phylogenetic trees with highly supported placements of tribes and subtribes. We also provide generally well-supported phylogenetic placements of 131 genera and 437 species that were not sampled by previous plastid and nuclear phylogenomic studies. Molecular clock analyses estimated the Orchidaceae origin at ~132 million years ago (Ma) and divergences of most subtribes from 52 to 29 Ma. Character reconstruction supports at least 14 parallel origins of epiphytism; one such origin was placed at the most recent common ancestor of ~95% of epiphytic orchids and linked to modern rainforests. Ten occurrences of rapid increase in the diversification rate were detected within Epidendroideae near and after the K-Pg boundary, contributing to ~80% of the Orchidaceae diversity. This study provides a robust and the largest family-wide Orchidaceae nuclear phylogenetic tree thus far and new insights into the evolution of epiphytism in vascular plants.

Abstract
Containing the largest number of species, the orchid family provides not only materials for studying plant evolution and environmental adaptation, but economically and culturally important ornamental plants for human society. Previously, we collected genome and transcriptome information of Dendrobium catenatum, Phalaenopsis equestris, and Apostasia shenzhenica which belong to two different subfamilies of Orchidaceae, and developed user-friendly tools to explore the orchid genetic sequences in the OrchidBase 4.0. The OrchidBase 4.0 offers the opportunity for plant science community to compare orchid genomes and transcriptomes and retrieve orchid sequences for further study.In the year 2022, two whole-genome sequences of Orchidoideae species, Platanthera zijinensis and Platanthera guangdongensis, were de novo sequenced, assembled and analyzed. In addition, systemic transcriptomes from these two species were also established. Therefore, we included these datasets to develop the new version of OrchidBase 5.0. In addition, three new functions including synteny, gene order, and miRNA information were also developed for orchid genome comparisons and miRNA characterization.OrchidBase 5.0 extended the genetic information to three orchid subfamilies (including five orchid species) and provided new tools for orchid researchers to analyze orchid genomes and transcriptomes. The online resources can be accessed at https://cosbi.ee.ncku.edu.tw/orchidbase5/.

Abstract
To improve our understanding of the origin and evolution of mycoheterotrophic plants, we here present the chromosome-scale genome assemblies of two sibling orchid species: partially mycoheterotrophic Platanthera zijinensis and holomycoheterotrophic Platanthera guangdongensis. Comparative analysis shows that mycoheterotrophy is associated with increased substitution rates and gene loss, and the deletion of most photoreceptor genes and auxin transporter genes might be linked to the unique phenotypes of fully mycoheterotrophic orchids. Conversely, trehalase genes that catalyse the conversion of trehalose into glucose have expanded in most sequenced orchids, in line with the fact that the germination of orchid non-endosperm seeds needs carbohydrates from fungi during the protocorm stage. We further show that the mature plant of P. guangdongensis, different from photosynthetic orchids, keeps expressing trehalase genes to hijack trehalose from fungi. Therefore, we propose that mycoheterotrophy in mature orchids is a continuation of the protocorm stage by sustaining the expression of trehalase genes. Our results shed light on the molecular mechanism underlying initial, partial and full mycoheterotrophy.

Abstract
Non-alcoholic steatohepatitis (NASH) is an important link for the progression of metabolic-related fatty liver disease to end-stage liver disease such as cirrhosis and hepatocellular carcinoma, which seriously endangers human health. NASH pathogenesis is complex, and involves the interaction between hepatic parenchymal and non-parenchymal cells (NPCs), sinusoidal endothelial cells, Kupffer cells, hepatic stellate cells, and so on. Herein, the relevant research progress of NPCs in the pathogenesis of NASH is reviewed in order to further understand the role of NPCs in NASH.

Abstract
Goodyerinae are one of phylogenetically unresolved groups of Orchidaceae. The lack of resolution achieved through the analyses of previous molecular sequences from one or a few markers has long confounded phylogenetic estimation and generic delimitation. Here, we present large-scale phylogenomic data to compare the plastome structure of the two main clades (Goodyera and Cheirostylis) in this subtribe and further adopt two strategies, combining plastid coding sequences and the whole plastome, to investigate phylogenetic relationships. A total of 46 species in 16 genera were sampled, including 39 species in 15 genera sequenced in this study. The plastomes of heterotrophic species are not drastically reduced in overall size, but display a pattern congruent with a loss of photosynthetic function. The plastomes of autotrophic species ranged from 147 to 165 kb and encoded from 132 to 137 genes. Three unusual structural features were detected: a 1.0-kb inversion in the large single-copy region of Goodyera schlechtendaliana; the loss and/or pseudogenization of ndh genes only in two species, Cheirostylis chinensis and C. montana; and the expansion of inverted repeat regions and contraction of small single-copy region in Hetaeria oblongifolia. Phylogenomic analyses provided improved resolution for phylogenetic relationships. All genera were recovered as monophyletic, except for Goodyera and Hetaeria, which were each recovered as non-monophyletic. Nomenclatural changes are needed until the broader sampling and biparental inherited markers. This study provides a phylogenetic framework of Goodyerinae and insight into plastome evolution of Orchidaceae.

Abstract
Osteosarcoma is a common malignant bone tumor that mainly affects children and adolescents. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is a member of the tumor necrosis factor superfamily. Caspase-8 appears in the upstream of apoptosis signaling pathway among caspases. We investigated TRAIL and caspase-8 levels in osteosarcoma patients to determine their correlation with cell proliferation and apoptosis. Osteosarcoma and osteochondroma patients receiving surgery in our hospital were selected. TRAIL and caspase-8 expression levels in tissue were determined by immunohistochemistry, and protein levels in cells were evaluated by western blotting. Human osteosarcoma cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. The osteosarcoma and osteochondroma cell cycles and apoptosis were investigated by flow cytometry. Correlation analysis was applied to TRAIL and caspase-8 levels during cell apoptosis. Positive TRAIL and caspase-8 expression rates in osteosarcoma tissue were significantly lower than in the controls (P < 0.05). TRAIL (0.114 ± 0.002) and caspase-8 (0.352 ± 0.124) levels in experimental cells were obviously lower than in the controls (P < 0.05). Osteosarcoma cells in the experimental group demonstrated higher proliferation and lower apoptosis at 24, 48, and 72 h (P < 0.05). The experimental cell number increased in the G1 stage and decreased in the S stage (P < 0.05). TRAIL and caspase-8 proteins showed positive correlation with apoptosis in osteosarcoma (P < 0.05). Human osteosarcoma presented reduced TRAIL and caspase-8 levels with enhanced cell proliferation and reduced apoptosis. TRAIL and caspase-8 expression levels were positively correlated with apoptosis in osteosarcoma.

Abstract
Porcine epidemic diarrhea poses significant sanitation problems in the porcine industry, and has negatively affected the economy in recent years. In this study, 48 fecal specimens were collected from piglets from four intensive swine farms located in the Gansu Province of China. The molecular diversity and phylogenetic relationships between porcine epidemic diarrhea viruses (PEDV) prevalent in Gansu were probed, and the resultant proteins were characterized. Sequence analysis of the spike protein (S) genes showed that each specimen had unique characteristics, and that the PEDV1/S/4 strain could be differentiated from the others via a unique mutation of the S gene. The phylogeny of S glycoprotein showed that all strains were clustered into two major groups. The four Gansu PEDV field strains were characterized into different groups; this finding was consistent with the results of the protein characterization prediction. This analysis additionally revealed the unique characteristics of each specimen. The results of this study could be used to elucidate the prevalence of PEDV and contribute to the prevention of PEDV in Gansu.

Abstract
A new binuclear complex, [Cd(ClCH2CH2CO2)2(phen)]2 (1), has been synthesized and structurally characterized by single crystal X-ray diffraction methods. The Cd atoms are linked by carboxylate oxygen atoms into a four-membered Cd2O2 rhombic ring with a Cd···Cd separation of 3.824 Å . Two carboxylate groups act as bidentate, and two as both bidentate bridging and bidentate chelating ligands. The hydrogen bonding and π-π stacking interactions are responsible for the supramolecular assembly and stabilization of the crystal structure. The complex has been characterized by elemental analysis, IR and UV/Vis spectra, and thermogravimetric and differential thermal analysis (TG/DTA). The complex exhibits blue fluorescence in the solid at room temperature.

Abstract
Incineration is a major treatment process for municipal solid waste in Taiwan. It is estimated that over 1.5 Mt of incinerator ash are produced annually. This study proposes using thermal plasma technology to treat incinerator ash. Sintered glass-ceramics were produced using quenched vitrified slag with colouring agents added. The experimental results showed that the major crystalline phases developed in the sintered glass-ceramics were gehlenite and wollastonite, but many other secondary phases also appeared depending on the colouring agents added. The physical/mechanical properties, chemical resistance and toxicity characteristic leaching procedure of the coloured glass-ceramics were satisfactory. The glass-ceramic products obtained from incinerator ash treated with thermal plasma technology have great potential for building applications.

Abstract
A total of 50 human umbilical cord blood (UCB) samples were studied. The hematopoietic stem/progenitor (CD34+) populations were isolated from UCB mononuclear cells (MNC) by means of immunomagnetic separation. Double immunofluorescent staining of UCB CD34+ cells revealed that there was a high proportion (82.33 +/- 4.47%) of CD34+ cells co-expressing CD13, while the percentage of CD34+ CD33+ cells was much lower (22.17 +/- 3.35%). In contrast, for co-expressing lymphoid differentiation antigens, the proportion of CD34+CD38+ cells (38.34 +/- 6.09%) was relatively higher than that of CD34+CD10+ cells (11.52 +/- 1.24%) or CD34+CD2+ cells (9.84 +/- 2.30%). For stimulating the ex vivo expansion of UCB progenitor cells, no single hematopoietic growth factor (HGF) was efficacious when used alone, while combination of 4 HGFs, such as GM-CSF, G-CSF, IL-3, and SCF could induce a 55-fold increase in the myeloid progenitor cells, day-14 CFU-GM, in a short term of 7 days' liquid culture. Cryopreservation of UCB as MNC preparations at -196 degrees C could satisfactorily retain the number and activity of CD34+ cells. After thawing, a high recovery rate of about 80% CD34+ cells was obtained. When suspended in liquid cultures containing a combination of 4 HGFs, as shown above, the frozen cord blood progenitor cells could be well expanded, reaching a >50-fold increase in day-14 CFU-GM, which was very similar to that of the fresh UCB samples. In addition, a similar result was also seen in CFU-GEMM, indicating that after cryopreservation the recovered UCB progenitor cells retain an intact clonogeneic ability capable of efficiently responding to hematopoietic growth factors for ex vivo expansion.

Abstract
We examined in vivo the effect of dietary fats and oils with different peroxidizability on protein carbonyl content, the presumed index of free radical-mediated protein oxidation. For 15.6 months, SHRSP (stroke-prone spontaneously hypertensive strain) rats were fed a diet supplemented with lard, safflower oil, perilla oil or fish oil/soybean oil, the peroxidizability of which increases in this order. The peroxidizability of tissue lipids was positively correlated with the protein carbonyl content in skeletal muscle, but not in the brain, heart or liver. The protein carbonyl content in the lard group was higher in the brain and liver compared to the other dietary groups. These results contradict the concept that long-term feeding of easily autoxidizable fatty acids allows the accumulation of lipid peroxides to accelerate the development of the free radical diseases, and suggest that tissue protein carbonyl content is not a simple reflection of autoxidizability-related lipid peroxidation but is also influenced by other biochemical processes.

Abstract
Previously, we demonstrated that several vegetable oils that included low-erucic rapeseed oil markedly shortened the survival time (by approximately 40%) of stroke-prone spontaneously hypertensive (SHRSP) rats as compared with perilla oil, soybean oil, and fish oil. We considered that a factor other than fatty acids is toxic to SHRSP rats, because the survival time-shortening activity could not be accounted for by the fatty acid compositions of these oils. In fact, a free fatty acid (FFA) fraction derived from lipase-treated rapeseed oil was found to be essentially devoid of such activity. A high-oleate safflower oil/safflower oil/perilla oil mixture exhibited a survival time-shortening activity comparable to that of rapeseed oil, but the activity of this mixed oil was also reduced by lipase treatment. A partially hydrogenated soybean oil shortened the survival time by approximately 40%, but a FFA fraction derived from lipase-treated partially hydrogenated soybean oil shortened it by 13% compared with soybean oil. Fatty acid compositions of the rapeseed oil and a FFA fraction derived from lipase-treated rapeseed oil were similar, but those of hepatic phospholipids of rats fed the oil and FFA were slightly but significantly different. These results support the interpretation that the survival time-shortening activity exhibited by some vegetable oils is due to minor components other than fatty acids, and that an active component(s) were produced in or contaminated soybean oil during the partial hydrogenation processes.

Abstract
A phospholipase A2 (OHV A-PLA2) from the venom of Ophiophagus hannah (King cobra) is an acidic protein exhibiting antiplatelet activity. In in vitro tests, OHV APLA2 showed a marked inhibitory effect on platelet aggregation induced by ADP, collagen and arachidonic acid in both human whole blood and platelet-rich plasma in a dose-dependent manner. The antiplatelet effects of OHV A-PLA2 did not increase when preincubation times of platelets and OHV A-PLA2 were prolonged indicating phospholipid hydrolysis did not significantly contribute to the antiplatelet effects. Alkylation of active site His residue using p-bromophenacyl bromide resulted in the complete loss of enzymatic activity, but the modified enzyme retained more than 30% of its antiplatelet effects. These results indicate that the antiplatelet effects of OHV A-PLA2 appear to be independent of its enzymatic activity, and there are separate sites responsible for the catalytic and antiplatelet activities.

Abstract
Preliminary experiments have shown that a diet containing 10% rapeseed oil (low-erucic acid) markedly shortens the survival time of stroke-prone spontaneously hypertensive (SHRSP) rats under 1% NaCl loading as compared with diets containing perilla oil or soybean oil. High-oleate safflower oil and high-oleate sunflower oil were found to have survival time-shortening activities comparable to that of rapeseed oil; olive oil had slightly less activity. A mixture was made of soybean oil, perilla oil, and triolein partially purified from high-oleate sunflower oil to adjust the fatty acid composition to that of rapeseed oil. The survival time of this triolein/mixed oil group was between those of the rapeseed oil and soybean oil groups. When 1% NaCl was replaced with tap water, the survival time was prolonged by approximately 80%. Under these conditions, the rapeseed oil and evening primrose oil shortened the survival time by approximately 40% as compared with n-3 fatty acid-rich perilla and fish oil; lard, soybean oil, and safflower oil with relatively high n-6/n-3 ratios shortened the survival time by roughly 10%. The observed unusual survival time-shortening activities of some vegetable oils (rapeseed, high-oleate safflower, high-oleate sunflower, olive, and evening primrose oil) may not be due to their unique fatty acid compositions, but these results suggest that these vegetable oils contain factor(s) which are detrimental to SHRSP rats.

Abstract
A phospholipase A2 (OHV A-PLA2) from the venom of Ophiophagus hannah (King cobra) is an acidic protein exhibiting cardiotoxicity, myotoxicity, and antiplatelet activity. The complete amino acid sequence of OHV A-PLA2 has been determined using a combination of Edman degradation and mass spectrometric techniques. OHV A-PLA2 is composed of a single chain of 124 amino acid residues with 14 cysteines and a calculated molecular weight of 13719 Da. It contains the loop of residues (62-66) found in pancreatic PLA2s and hence belongs to class IB enzymes. This pancreatic loop is between two proline residues (Pro 59 and Pro 68) and contains several hydrophilic amino acids (Ser and Asp). This region has high degree of conformational flexibility and is on the surface of the molecule, and hence it may be a potential protein-protein interaction site. A relatively low sequence homology is found between OHV A-PLA2 and other known cardiotoxic PLA2s, and hence a contiguous segment could not be identified as a site responsible for the cardiotoxic activity.

Abstract
AIM To observe the effect of captopril (Cap) on intracellular pH (pHi) in aortic smooth muscle cells (ASMC). METHODS Cultured ASMC derived from rat and rabbit aortae were loaded with the fluorescent dye BCECF and pHi was determined using digital image processing method. RESULTS The pHi of untreated SHR and WKY rats were 7.37 +/- 0.29 and 7.19 +/- 0.31, respectively. Oral Cap decreased pHi (7.11 +/- 0.26, P < 0.05) and exaggerated pHi response to angiotensin II (Ang-II, 0.1 mumol.L-1) in ASMC of SHR rats vs WKY rats (0.14 +/- 0.05 vs 0.21 +/- 0.05 pH units, P < 0.01). Cap in vitro had no effect on Ang-II induced intracellular alkalinization in ASMC of rabbits. CONCLUSION Oral Cap inhibits Na+(-)H+ exchange activity in ASMC of SHR rats.

Abstract
Low-fat conventional diets supplemented with 5 or 10% vegetable oils were fed to stroke-prone spontaneously hypertensive rats (SHR-SP) from weaning and the mean survival times were determined. A 1% aqueous sodium chloride solution was used as drinking water throughout the experiments. In four separate experiments, the rapeseed oil group showed a significantly shorter mean survival time. The relative mean survival times were 50-59% (rapeseed oil group), 78-100% (soybean oil group) and 86% (microbial oil group) as compared with the group fed perilla oil (100%). The group which received 4-fold diluted rapeseed oil exhibited a significantly shorter survival time as compared with the group receiving soybean oil. Although the feeding experiments were performed under very simple and restricted conditions, these results suggest that the rapeseed oil prepared for human use contains a factor (s) which is toxic to SHR-SP rats.

Abstract
Previously, we noted significant differences in the behavioral patterns of mice fed safflower oil with a very low alpha-linolenate/linoleate ratio and perilla oil with a high alpha-linolenate/linoleate ratio from mothers to offsprings. In this report, we compared the behavior and drug responses in mice fed diets containing six different vegetable oils-corn, rapeseed, soybean, safflower, perilla and a mixture of perilla and safflower oils- for a relatively short period: 8 months after weaning. Soybean oil is a component of most conventional diets and was used as a control. The alpha-linolenate/linoleate ratios of the oils appeared to affect the locomotor activities in a wheel cage: the activity decreased in the order of safflower, the mixture (1:1) and the perilla oil groups. However, the rapeseed oil group exhibited much higher locomotor activity than that expected from the alpha-linolenate/linoleate ratio. Additionally, the rapeseed oil group exhibited unusual behavior patterns, including higher ambulation and rearing activities, faster acquisition of the water maze task and slower habituation behavior as compared with the control group. Susceptibility to pentobarbital anesthesia tended to be higher in the rapeseed oil group. The differences in the alpha-linolenate/linoleate ratios of these oils alone do not account for the observed differences in the behavioral patterns among the six dietary groups. Although we cannot exclude the possibility that the observed behavioral anomaly is due to the unique fatty acid composition of rapeseed oil, we speculate that a factor(s) other than fatty acids in rapeseed oil affected nervous system functions.

Abstract
AIM To determine whether angiotensin-converting enzyme inhibitors can affect Ca2+ handling in cultured aortic smooth muscle cells (ASMC) directly. METHODS Cultured ASMC derived from rat aorta were loaded with the intracellular Ca2+ ([Ca]2+i) fluorescent indicator Fura 2-AM and digital image processing technique was used. RESULTS Resting [Ca2+]i was greater in ASMC from SHR vs WKY (P < 0.01). KCl-, norepinephrine (NE)-, and angiotensin II (Ang)-induced [Ca2+]i increases were enhanced in ASMC of SHR vs WKY (220 +/- 6, 212 +/- 8, and 215 +/- 14 vs 199 +/- 6, 202 +/- 7, and 195 +/- 7 nmol.L-1, respectively). Captopril (Cap) and enalapril (Ena) had no inhibitory effect on KCl-, NE-, and Ang-induced [Ca2+]i increases in ASMC of WKY. Cap and Ena inhibited KCl-, NE-, and Ang-increased [Ca2+]i in ASMC of SHR (210 +/- 7, 194 +/- 6, and 201 +/- 6 nmol.L-1, respectively). Ena and nifedipine similarly decreased KCl-, NE-, and Ang-increased [Ca2+]i. CONCLUSION Cap blocked KCl-, NE-, and Ang-increased ([Ca2+]i) via a voltage-dependent Ca2+ channel of which function and specificity was altered in ASMC of SHR.

Abstract
An acidic phospholipase A2 (OHV A-PLA2) isolated from the venom of the king cobra (Ophiophagus hannah) was tested for its ability to cause pathological changes to myocardium, skeletal muscle and cardiac ganglia. White mice were injected intravenously with dose of 8 mg/kg or 4 mg/kg of OHV A-PLA2 and tissue samples were taken at 6 or 24 hr. Light microscopic examination failed to show significant changes in cardiac muscle and ganglia. Skeletal muscle showed myofibre degeneration and necrosis. Electron microscopic study revealed myodegeneration in cardiac and skeletal muscles, and reduction in synaptic vesicle population of preganglionic nerve terminals in cardiac ganglia. Ultrastructural changes in tissues were dose related. The lower dose (4 mg/kg) of OHV A-PLA2 produced mild myocardial changes, the myofilaments were intact but contracted, and the A band and I band were skewed. OHV A-PLA2 caused myocardial degeneration at a higher dose of 8 mg/kg. The changes included dissolution of actin and myosin filaments, dilatation and disorganization of sarcoplasmic reticulum and degeneration of mitochondria. The skeletal muscle lesions were more severe than the myocardial changes. Some of the myofibrils were severely disorganized and lack typical striated appearance, sarcomeres disrupted, most of mitochondria were vesiculated and destroyed.

Abstract
The transposon derivative has been placed on a transposition suicide vector to yield pDB30 in Escherichia coli WA803. A simple method, using a Tn5 derivative Tn5-Lux, has been successfully devised for the introduction and stable expression of the bioluminescence property in Pseudomonas sp., Agrobacterium sp., and Rhizobium sp. In this study, there was also successful mating between Escherichia coli WA803(pDB30) and strains of Acromonas hydrophila and Plesiomonas shigelloides. These bacteria emitted bioluminescence after they gained pDB30 by transconjugation.

Abstract
RapID onE System is a newly developed four-hour rapid diagnostic kit for the identification of enteric bacteria. To know the effectiveness of this system, we used 125 strains of oxidase-negative, gram-negative bacilli for this evaluation. Except for Acinetobacter calcoaceticus, all the bacilli belong to family Enterobacteriaceae. The bacterial strains of this assessment belong to 12 genera and 20 species. Among them, 84 strains were freshly isolated from clinical specimens and 41 strains were frozen (-70 degrees C) stock clinical isolates. The results show that 115 (92.0%) strains were correctly identifed to the species level. It yielded 92.9% and 90.2% of correct identification of fresh isolates and frozen stocks, respectively. In this paper, the reading criteria of RapID onE System would also be discussed.

Abstract
Occurence of ankyloglossi and its effect on pronuncing clarity has not been reported in detail at home and abroad.Academic circles have defferent opinions on it till now.This article describes the occurrence of ankyloglossi and its effect on pronouncing clarity,based on the sample investigation made on three different age groups children(3,000 children).It is found that younger children have higher occurrence of ankyloglossi,but which has little influence on pronouncing clarity.Pronouncing clarity mainly depends on the increase of age and the ripe of language ability.

Abstract
An acidic phospholipase A2 (OHV A-PLA2) purified from Ophiophagus hannah venom had a cardiotoxic action on rat heart. In rats OHV A-PLA2 (2-4 mg/kg) caused ECG abnormalities including decreased heart rate, prolonged P-R interval, widened QRS complex and complete A-V block. When tested on isolated rat right atria, OHV A-PLA2 (10-20 micrograms/ml) produced a positive chronotropic effect. When tested on isolated rat left atria or papillary muscle preparations, OHV A-PLA2 (2.5-20 micrograms/ml) caused positive inotropic effect, followed by contracture. The positive inotropic effects could be abolished by high Ca2+ and enhanced by low Ca2+; both treatments accelerated contracture. The contracture could be inhibited in Mn2+ (5 mM)-containing medium and abolished by Ca(2+)-free bath solution containing 1 mM EDTA. The cardiotoxic action of OHV A-PLA2 was not influenced by verapamil, tetrodotoxin, propranolol, phentolamine, atropine or indomethacin. It is suggested that the cardiotoxic effects of OHV A-PLA2 may result from increasing intracellular levels of Ca2+.

Abstract
Adriamycin and daunomycin anticancer drugs are detectable in leukemias and solid tumors by cell fluorescence. We observed initial cytoplasmic fluorescence followed by slow nuclear localization of adriamycin and daunomycin after incubation with cultured human squamous cell (P3, FADU) and adenocarcinoma (HT29, SW620) lines by digital video imaging microscopy. Tumor cells incubated with 10 mug/ml of these drugs exhibited increased uptake for more than 3 h with intracellular levels in the range 0.5-2.5 mug/10 6 cells measured by dimethyl sulfoxide (DMSO) extraction and fluorescence spectrophotometry. Daunomycin had 10- to 100-fold higher toxicity for these carcinoma cells than for normal human epithelial keratinocytes measured by in vitro MTT tetrazolium assays. The viability of daunomycin-sensitized carcinoma cells was decreased 2- to 10-fold further by argon laser illumination at 488 nm (5W, T max = 8 degrees C) for 2-3 minutes. The results suggest that adriamycin derivatives may be useful targeting agents for adjuvant treatment and chemophototherapy of human solid tumors by MR-guided laser fiberoptic endoscopy.

Abstract
Primary human oral keratinocytes were transformed by transfection with recombinant human papillomavirus type 16 (HPV-16) DNA, and two transformed cell lines named human oral keratinocytes-16A and -16B (HOK-16A and HOK-16B) were established. While normal cells and cells transfected with vector only exhibited a limited lifespan, the HOK-16A and HOK-16B lines demonstrated immortality and altered morphology from their normal counterpart. The HOK-16A and HOK-16B lines contained approximately 40 and approximately 25 copies of intact HPV-16 DNA as integrated form per cell respectively, and both cell lines expressed several viral specific poly(A+) RNAs. Notably these cell lines also overexpressed cellular myc proto-oncogene in comparison with the normal counterpart. However, the immortalized cell lines were not able to produce tumors in nude mice, indicating that the cells are partially transformed. The HOK-16A and HOK-16B lines are, therefore, useful for investigating the multistep molecular events of oral carcinogenesis.

Abstract
Clobetasol propionate (Temovate), a novel high-potency topical corticosteroid, was used in open trial from 1987 to 1988 on 24 patients with persistent oral vesiculoerosive disease of at least 1 month's duration. Fourteen women and 10 men, ranging in age from 27 to 76 years (mean 48 years), participated. Nine patients had erosive lichen planus, one had benign mucous membrane pemphigoid, three had pemphigus vulgaris, seven had persistent major recurrent aphthous stomatitis, and four had chronic oral erythema multiforme. Fifteen patients had complete remission of signs and symptoms, seven had excellent response of signs and complete remission of symptoms, and two failed to respond. All other topical therapy was suspended before and during the study. All patients responded to two or three applications daily of medication. Side effects were minor and reversible, and included localized candidiasis (three patients), stomatopyrosis (two), and hypogeusia (one). Clobetasol propionate ointment in adhesive paste (Orabase) thus seems to be an effective topical steroid alternative to other less potent topical and systemic drugs for recalcitrant oral vesiculoerosive disease.
