The immune response to sheep red blood cell (sRBC) was monitored in the mice infected with Ascaris strum or Trichinella spiralis. The effects of the infection with T. spiralis or the injection with cyclophosphamide (CY) as an immunosuppression agent prior to challenge infection with the embryonated eggs of A. suum were monitored in mice by means of the level of infection with A. strum and cellular and humoral immune response to sRBC. following the oral administration of 1, 000 eggs of A. suum to mice, delayed-type hypersensitivity (DTH) and rosette-forming rate were gradually decreased and reached to the lowest levels at the 5th week and 6th week postinfection, respectively, and then returned to normal at the loth week. The hemagglutinin (HA) and hemolysin (HE) titers were gradually elevated and reached to peak at the 3rd week postinfection, and then returned to normal level. The appearance ratios of the eosinophils and mast cells were in peak at the 4th week and the 2nd week postinfection, respectively. Meanwhile the harvest ratio of A. suum larvae from the liver and lungs was 21.97% at the 1st week postinfection. Following the oral administration of 300 T. spiralis infective larvae, DTH and rosette-forming rate were gradually decreased with the lapse of time and reached the lowest values in the 30th and 21st day of postinfection, and then slightly increased and transiently decreased in the 70th and 80th day of postinfection, respectively. HA and HE titers were the lowest in the 21st and 90th day, whereas the ratios of eosinophils and mast cells were the highest on the 40th and 14th day posti nfecti on, ruts petit i vela. Following the intraperitoneal injection of CY, the body weight, the spleen weight, DTH, rosette-orming ratio, HA and HE titers, the number of WBC and the ratio of the mast cell were predominantly decreased in the 5th day, and then returned to the same value of the 1st day postinjection. The ratio of eosinophils was gradually decreased following to advance of days. At the 1st, 5th and loth days after intraperitoneal injection of CY of 400 mg/kg, a dose with 1, 000 eggs of A. suum was administered orally to mice, and harvest rate of the larvae at the 7th day postadministration was 7.07% in the 1st day, 14.94% in the 5th day, 10.1% in the loth day, 8.02% in control group. The effect of prior infection with infective larvae of T. spiralis upon immunological sequelae of a challenge infection of mice with embryonated eggs of A. suum in 30 or 70 days interval was checked. On the 37th day of prior infection with T. spiralis, that was the 7th day with A. suum postinfection, DTH and rosette-forming rate were drastically decreased, but the ratio of mast cells was highly increased and the ratio of eosinophils, HA and HE titers were fairly increased. On the other hand, the rate of larvae harvest was 9.3% in experimental group in contrast with 22.18% in control group. Meanwhile the effect of immune response to sRBC was similar to that of the former, but DTH and rosettt-forming rate were greatly decreased in the 77th day after prior infection with the 7th day after challenge infection in compariton with control. At that time, Ascaris larvae were harvested 8.3% in experimental group in comparison with 10.5% in control group.

A 11-month-old infancy was referred for treatment of cleft palate. The patient's congenital deformities had included oronasal fistula on the soft palate and bifid uvula. Furrow double-opposing Z-plasty was performed under general anesthesia. However, postoperative bleeding developed at ward. Despite the pressure of operative wound, venous oozing continued and hemoglobin concentration and RBC were decreased (Hb: 5.5g/dL, RBC: $1.98{\times}10^6/mm^3$). The patient was pale and confused and transferred to Surgical Intensive Care Unit(SICU) We could not keep the peripheral venous line and there was a high risk of hypovolemic shock. Emergency transfusion was performed through the central femoral venous line and emergency operation for bleeding control was carried out. We explored the operation site and found bleeding point from the posterior pharyngeal wall. Electrocoagulation and surgicel packing were carried out and bleeding was stopped.

Detailed morphological studies and molecular analyses based on plastid-encoded rbcL gene sequences were undertaken on Peyssonnelia species, a poorly known genus from Korea. We report new records for the Korean coast, Peyssonnelia harveyana and P. rumoiana. Peyssonnelia harveyana is chiefly characterized by P. rubra-type anatomy, closely packed perithallial filaments in firm matrix, hypothallial filaments arranged in parallel rows, thalli with appressed margins, hypobasal calcification, and unicellular rhizoids. Peyssonnelia rumoiana is principally characterized by two vegetative features, hypothallial filaments arranged in a polyflabellate layer, and perithallial filaments arising from the whole upper surface of each hypothallial cell (Peyssonnelia rubra-type anatomy). Our rbcL analyses revealed that P. harveynana and P. rumoiana were placed within a clade of Peyssonnelia. We also propose the new combination, Sonderophycus cauliferus comb. nov., for previous Peyssonnelia caulifera. Phylogenetic analyses revealed that our S. cauliferus was placed within a clade of Sonderophycus.

It was confirmed that we got somewhat different results even though we performed same items with same methods from capillaries and venous blood of healthy 72 cases. Items which capillaries blood has higher value than venous blood are the numbers of erythrocyte, lymphocyte, basophil, hematocrit, MCHC and RDW. Total numbers of RBC (p<0.035), lymphocyte and basophil are shown statistically significance. Items which venous blood has higher value than capillary blood are the numbers of platelet (p<0.00) and neutrophil (p<0.01). Fallible items in clinics can be shown the numbers of RBC, platelet, lymphocyte and neutrophil because we got somewhat different results even though we performed same items with same methods from capillaries and venous blood, respectively. It is necessary to choose the clear criteria and normal value depends on clinical specimen as the number of platelets are measured with an abnormal value shown over 40% down. As normal difference according to each item and method is currently acceptable and applicable in clinics, it is considered that a new normal value depends on clinical specimen should be established and is to be useful positively in clinics.

When the generitype Centroceras clavulatum, a presumed cosmopolitan warm temperate to tropical red alga, was discovered to have a biogeographic distribution limited to the Pacific Ocean using molecular and morphological evidence, the taxonomy in the genus Centroceras was thrown into chaos worldwide. An analysis of what species was, or were, previously identified as C. clavulatum in Bermuda is the focus of the present molecular (COI-5P, rbcL) and morphological study. Two novel species are proposed, C. arcii sp. nov. and C. illaqueans sp. nov., and the distributions of three taxa recently segregated in the 'C. clavulatum complex' of the western Atlantic, C. gasparrinii, C. hyalacanthum, and C. micracanthum, have been expanded to include Bermuda. C. arcii is shown to be morphologically cryptic with C. micracanthum, and remains best distinguished by its COI-5P barcode sequence.

Floating debris provides substrates for dispersal of organisms by ocean currents, including algae that thrive on plastics. The 2011 earthquake and tsunami in Tohuku, Japan resulted in large amounts of debris carried by the North Pacific Current to North America from 2012 to 2016. In 2015-2016, the plastics in the debris bore a complex biota including pink algal crusts. One sample (JAW4874) was isolated into culture and a three-gene phylogeny (psbA, rbcL, and SSU) indicated it was an unknown member of the red algal class Stylonematophyceae. It is a small pulvinate crust of radiating, branched, uniseriate filaments with cells containing a single centrally suspended nucleus and a single purple to pink, multi-lobed, parietal plastid lacking a pyrenoid. Cells can be released as spores that attach and germinate to form straight filaments by transverse apical cell divisions, and subsequent longitudinal and oblique intercalary divisions produce masses of lateral branches. This alga is named Tsunamia transpacifica gen. nov. et sp. nov. Sequencing of additional samples of red algal crusts on plastics revealed another undescribed Stylonematophycean species, suggesting that these algae may be frequent on drift oceanic plastics.

Iron deficiency anemia (IDA) is the world's most common nutritional problem. It is characterized by a low hemoglobin (Hb) level and low iron status. A study was conducted to investigate the incidence of iron deficiency anemia in day scholar girls belonging to different socioeconomic strata at Punjab University, Lahore. Iron status of the subjects was estimated by measuring Hb, hematocrit (Hct), red blood cell (RBC) count, mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCR), serum iron, serum ferritin, total protein and albumin. Results indicated that females belonging to low socioeconomic strata had lower values for Hb, Hct, RBC count, total protein and albumin. Serum iron, serum ferritin, MCV and MCH values fell within the normal range for all of the socioeconomic groups. However, serum iron and ferritin varied with socioeconomic status and higher-income groups had significantly higher serum iron and ferritin. It was concluded that anemia may develop due to poor intake and absorption of iron and that those in the low-income bracket are the most affected group.

An economic marine alga, which is considered to be an important source of carrageenan, was collected from Jindo of the southern coast of Korea. This species shares the vegetative and female reproductive features of Ahnfeltiopsis and is characterized mostly by its small size (up to 8 cm), terete to subterete thalli at the lower portion, cartilaginous in texture, dichotomous branches, rarely produced proliferations, and an absence of hypha-like filaments in the medulla. It is distinguished from other Korean species within the genus by the thallus feature. In a phylogenetic tree based on the molecular data, this alga nests in the same clade with A. concinna from Japan but forms a sister clade to A. concinna from Mexico and Hawaii (type locality). However, the genetic distance among those sequences was calculated as 0.1-1.3% for rbcL and 1.1% for COI sequences, considered to be intraspecific variation within the genus. Based on the morphology and molecular analysis, this alga is identified as A. concinna originally described from Hawaii. This is the first record of the species in the Korean marine algal flora.

Automatic hematology analyzers provide the leukocyte differential count and the useful flags of the various hematological parameters. We compared LH 750 (Beckman Coulter Co., Miami, FL, USA) with manual method on differential leukocyte counts and evaluated the usefulness of the suspect flags, provided by this instrument. The comparison of leukocyte differential counts between two methods showed good correlation coefficient (r), which were 0.95 (neutrophil), 0.92 (lymphocyte), 0.82 (monocyte) and 0.95 (eosinophil). The frequency of the total flags displayed on LH 750 were 15.5%, which included immature granulocyte/left shift 63.5%, nucleated RBC 14.6%, platelet clumps 13.1%, variant lymphocyte 50% and blast 16.6%. This instrument showed higher positive predictive value in the flags such as platelet clumps 68.8%, immature granulocyte/left shift 61.5%, nucleated RBC 27.3%, variant lymphocyte 50% and blast 16.7%. In this study, the leukocyte differential counts of LH 750 showed good correlation with manual method and the suspect flags also showed a good performance for applying the criteria of re-examination in the clinical laboratory.
