Protein-energy malnutrition is regarded as one of the public health problems in developing countries as a result of poor feeding practices due to poverty. This study, therefore, aimed at evaluating nutritional quality of a potential weaning food formulated from locally available food materials. The cooking banana fruit(CB) and bambara groundnut seeds(BG) were purchased from local market in Akure, Ondo State, Nigeria. The CB and BG were processed into flours, mixed in ratios of 90:10, 80:20, 70:30 and 60:40 and subjected into proximate, sensory and biochemical analyses using standard procedures. Nutrend(a commercial formula) and ogi(corn gruel, a traditional weaning food) were used as control. The nutritient composition(g/100 g) of the food samples were ranged as follows: moisture 2.94-6.94, protein 7.02-16.0, ash 1.76-2.99, fat 0.76-8.45, fibre 1.52-3.75, carbohydrate 63.84-88.43 and energy 1569.8-1665.7 kcal. The biological value(BV), net protein retention(NPR), protein efficiency ratio(PER) and feed efficiency ratio(FER) of the experimental food samples were significantly(p<0.05) lower than nutrend, but higher than ogi. The haematological variables of rats fed with formulated food samples, commercial formula(nutrend) and traditional weaning food(ogi) were not significantly(p>0.05) influenced by the dietary treatment. However, the values obtained for red blood cell(RBC), white blood cell(WBC), pack cell volume(PCV) and erythrocyte sedimentation rate(ESR) were higher in the experimental food samples than the commercial food. The growth rate of animals fed with experimental food samples were lower than those fed with the nutrend, but higher than those fed with ogi. In conclusion, the nutritional quality of CB and fermented BG mix of 60:40 ratio was better than ogi; and comparable to the nutrend. This implies that it can be used to replace low quality traditional weaning food and the expensive commercial weaning formula.

The genus Cenchrus (Poaceae), containing ca. 97 species, is distributed throughout Australia, Africa and Indian sub-continent and which was introduced to the United States and Mexico for use in improved pasture. In Korea, especially Daecheong Island, it is one of the most hazardous invasive plant, which causes serious environmental threats, biodiversity damages and physically negative impact on humans and animals. It can cause serious damage to farms, fields and white sand beaches. However, the chloroplast (cp) genome sequences and information of Cenchrus longispinus have been not addressed, so we provide the complete cp genome of Cenchrus longispinus using next-generation sequencing technology. The size of cp genomes of this Daecheong Island species (Cenchrus longispinus) is 137,144 bp, and it shows a typical quadripartite structure. Consisting of the large single copy (LSC; 80,223 bp), small single copy (SSC; 12,449 bp), separated by a pair of inverted repeats (IRs; 22,236 bp). This cp genome contains 75 unique genes, 4 rRNA coding genes, 33 tRNA coding genes and 21 duplicated in the IR regions, with the gene content and organization are similar to other Poaceae cp genomes. Our comparative analysis identified four cpDNA regions (rpl16, rbcL, ndhH and ndhF) from three Cenchrus species, two Setaria species and one Pennisetum species which may be useful for molecular identification.

We have previously demonstrated that overexpression and characterization of Brassica rapa type-l metallothionein gene (BrMT1) in Arabidopsis which showed enhanced resistance to cadmium and ROS. Here, we present the consistent study of our previous report about BrMTs. BrMT3 expressing DTY167 cells showed resistance to Zn and Pb as well as Cd. Thus, we have developed the BrMT3 overexpression Arabidopsis to enhance capacity for metal stresses. Successful expression and localization were achieved using the rubisco transit peptides of RbcS-BrMT3-GFP protein, which was confirmed by western blot analysis with the GFP antibody and green fluorescence signal from the chloroplast. BrMT3 overexpression Arabidopsis plants exhibited a higher resistance to cadmium compared to control plants. This result indicates that BrMT3 would be applicable to the development of plants with enhanced resistance against heavy metal stresses.

The hematologic effect by low-concentration and repeated exposure to mixed organic solvent remains obscure. This study was performed to evaluate the hematologic effect by mixed organic solvent exposure, especially on the type of anemia by mean corpuscular volume(MCV) and red blood cell distribution width(RDW). The subject were 64 organic solvent workers(male 4, female 60) and 78 general workers(male 18, female 60) who showed anemic tendency in worker's health examination which carried out by Pusan Paik Hospital from January to December, 1988. The author gained some hematologic findings(hemoglobin, hematocrit, RBC, WBC, MCV, MCHC, platelet count, ESR, RDW) from auto-analysis method by coulter counter S plus IV, and compared the type of anemia by MCV and RDW. In the pilot study for estimating the prevalence of anemia according to the type of b, the prevalence rate was higher in organic solvent workers than in public officials as 10.9% and 4.1% respectively. There were statistical significance in the value of hemoglobin, hematocrit, MCV, MCHC, platelet count, ESR, RDW between the two study groups with more severe anemic tendency in organic solvent workers. The type of anemia in organic solvent workers was microcytic and anisocytic with the mean value of $68.28{\pm}8.3fL$ of MCV and $19.1{\pm}4.0%$ of RDW.

The establishment of a DNA barcode database at the regional scale and assessments of the utility of DNA barcodes are crucial for conservation biology and for the sustainable utilization of biological resources. Schisandraceae is a small family consisting of ca. 45 species. It contains many economically important species, such as Schisandra chinensis, which is widely used as a source in tonic beverages and in oriental medicine. In Korea, three species, S. chinensis, S. repanda, and Kadsura japonica, are distributed. We evaluated the level of variation of the DNA sequences of rbcL, matK, and the ITS regions from 13 accessions representing the distributional range of the three species. The three DNA barcode regions were easily amplified and sequenced. The minimum values of the interspecific genetic distances among S. chinensis, S. repanda, and K. japonica either separately or in combination are 4- to 23-fold higher than the maximum value of the intraspecific distance, showing that there is a clear DNA barcoding gap in the regions for Korean Schisandraceae. Phylogenetic analyses of the three DNA barcode regions, separately and simultaneously, indicate that all of the DNA barcode regions are useful for identifying a species of Schisandraceae in Korea. The distinctiveness of the three species of Schisandraceae was also supported at the species level when Chinese and Japanese populations were added. The results of this study indicate that three concatenated regions constitute the best option for DNA barcoding in Schisandraceae in Korea.

Objectives : Allergic rhinitis is an inflammation or irritation of the mucous membranes that in the nose. Common symptoms include sneezing; a stuffy or runny nose; itch eyes, nose and throat; and watery eyes. We aimed to determine therapeutic effect of Onpye-tang by observing changes in blood cells and the nasal mucosal tissue. Methods : Twenty-four Sprague-Dawley rats were divided into three groups: normal, control, and sample group. Allergic rhinitis was induced in the control and sample group by intraperitoneal and intranasal sensitization with 0.l% Ovalbumin solution. Then Onpye-tang was orally administered only to the sample group for 28days, while the rats in the control group was given normal saline. We observed changes in the number of RBC and WBC; changes of neutrophils, lymphocyte, monocyte, and eosinophil proportions; total IgE level and AST & ALT change; also, changes in the nasal mucosal tissue. We used Student T-test statistically(p<0.05). Results : Onpye-tang showed significantly decreased IgE level on the serum of the rat model. Onpye-tang showed significantly decreased eosinophil level on the blood of the rat model. Onpye-tang inhibited the inflammatory reaction on the nasal mucosal tissue, according to nasal mucosal biopsy. Onpye-tang showed an inhibitory effect on the process of allergic rhinitis, according to IgE level, Eosinophil level, nasal mucosal biopsy. Onpye-tang had no hepatoxicity, according to AST and ALT on the serum. Conclusion : According to the above results, it is considered that Onpye-tang has an inhibitory effect on the process of allergic rhinitis and it can be used in relieving symptoms of allergic rhinitis.

Background: Species in the heterokont genus Synura are colonial and have silica scales whose ultrastructural characteristics are used for classification. We examined the ultrastructure of silica scales and molecular data (nuclear SSU rDNA and LSU rDNA, and plastid rbcL sequences) to better understand the taxonomy and phylogeny within the section Petersenianae of genus Synura. In addition, we report the first finding of newly recorded Synura species from Korea. Results: We identified all species by examination of scale ultrastructure using scanning and transmission electron microscopy (SEM and TEM). Three newly recorded species from Korea, Synura americana, Synura conopea, and Synura truttae were described based on morphological characters, such as cell size, scale shape, scale size, keel shape, number of struts, distance between struts, degree of interconnections between struts, size of base plate pores, keel pores, base plate hole, and posterior rim. The scales of the newly recorded species, which belong to the section Petersenianae, have a well-developed keel and a characteristic number of struts on the base plate. We performed molecular phylogenetic analyses based on sequence data from three genes in 32 strains (including three outgroup species). The results provided strong statistical support that the section Petersenianae was monophyletic, and that all taxa within this section had well-developed keels and a defined number of struts on the base plate. Conclusions: The phylogenetic tree based on sequence data of three genes was congruent with the data on scale ultrastructure. The resulting phylogenetic tree strongly supported the existence of the section Petersenianae. In addition, we propose newly recorded Synura species from Korea based on phylogenetic analyses and morphological characters: S. americana, S. conopea, and S. truttae.

Rockfish, Sebastes schlegelii (mean length $14.53{\pm}1.14cm$ and mean weight $38.36{\pm}3.45g$), were exposed for 4 weeks with the different levels of ammonia in the concentrations of 0, 0.1, 0.5, and 1.0 mg/L at 19 and $24^{\circ}C$. The indicators of growth performance such as daily length gain, daily weight gain, condition factor, and hematosomatic index were significantly reduced by the ammonia exposure and high temperature. The ammonia exposure induced a significant decrease in hematological parameters, such as red blood cell (RBC) count, white blood cell (WBC) count, hemoglobin (Hb), and hematocrit (Ht), whose trend was more remarkable at $24^{\circ}C$. Mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC) were also notably decreased by the ammonia exposure. Blood ammonia concentration was considerably increased by the ammonia concentration exposure. In the serum components, the glucose, glutamic oxalate transaminase (GOT), and glutamic pyruvate transaminase (GPT) were substantially increased by the ammonia exposure, whereas total protein was significantly decreased. But, the calcium and magnesium were not considerably changed.
