The purpose of this survey is to investigate the nutritional status and dietary intake of gastrectomized cancer patients in Asan Medical Center. The subjects were 98 patients, who underwent a gastrectomy due to gastric cancer and were admitted to the General Surgery Department during March 2007 to December 2007. We examined general characteristics (sex, age, clinicopathological stage, type of operation), anthropometric data (height, weight change), biochemical data (red blood cell RBC, hemoglobin HGB, hematocrit HCT, mean corpuscular volume MCV, total lymphocyte count TLC, albumin, total cholesterol), dietary intake and dietary intake related symptoms. Weight loss of gastrectomized patients was $9.0{\pm}4.3$% from preillness weight to visiting out-patient department (OPD) weight. Biochemical data (RBC, HGB, HCT, MCV, TLC, albumin, total cholesterol) significantly deteriorated after gastrectomy. However, outpatient visits were all restored to the normal range. Postoperative energy intake was $785.0{\pm}164.2$ kcal, which corresponds to $41.6{\pm}9.6$% of daily energy requirement. The cause of poor oral intake is mostly fear, abdominal pain and abdominal discomfort. Therefore, to control pre-or post-operative weight change in the future requires, focusing on the body weight to maintain a normal or usual nutrition by interventions and increased caloric intake during hospitalization for the development of nutrient-dense meals. In addition, as the main reason of the lack of intake of meals after the gastrectomy was fear, the patients should be actively encouraged to consider the importance of eating proper meals.

Purpose: The aim of this study was to elucidate the prognosis, and other clinical features, such as time to surgery and the amount of transfusion, of small bowel injury (SBI) accompanied by liver injury (LI). Methods: We investigated 221 patients with SBI who visited an emergency center from October 2000 to March 2019. We excluded patients with injuries that directly led to mortality, and the remaining 149 patients were divided into the SBI alone (SBI-A) group and the SBI accompanied by LI (SBI-LI) group. Data were collected for preoperative and surgical outcome variables, and the treatment results were compared between groups. Results: The SBI-LI group had a higher mortality rate than the SBI-A group (22.4% vs. 14.3%), but this difference was not statistically significant (p=0.061). There were no significant differences between the SBI-A and SBI-LI groups, except for the amount of red blood cell (RBC) transfusion (SBI-A: 3.53±0.1 vs. SBI-LI: 8.38±0.7 packs, p=0.035) and the length of intensive care unit (ICU) stay (SBI-A: 6.7±0.2 vs. SBI-LI: 11.1±0.5 days, p=0.047). Conclusions: The SBI-LI group required more RBC transfusions and longer ICU stays than the SBI-A group. SBI accompanied by LI may show higher mortality than SBI alone; however, since the difference was not statistically significant in the present study, larger-scale follow-up research is needed.

BACKGROUND/OBJECTIVES: An increasing life expectancy in society has burdened healthcare systems substantially because of the rising prevalence of age-related metabolic diseases. This study compared the effects of animal protein hydrolysate (APH) and casein on metabolic diseases using aged mice. MATERIALS/METHODS: Eight-week-old and 50-week-old C57BL/6J mice were used as the non-aged (YC group) and aged controls (NC group), respectively. The aged mice were divided randomly into 3 groups (NC, low-APH [LP], and high-APH [HP] and fed each experimental diet for 12 weeks. In the LP and HP groups, casein in the AIN-93G diet was substituted with 16 kcal% and 24 kcal% APH, respectively. The mice were sacrificed when they were 63-week-old, and plasma and hepatic lipid, white adipose tissue weight, hepatic glucose, lipid, and antioxidant enzyme activities, immunohistochemistry staining, and mRNA expression related to the glucose metabolism on liver and muscle were analyzed. RESULTS: Supplementation of APH in aging mice resulted in a significant decrease in visceral fat (epididymal, perirenal, retroperitoneal, and mesenteric fat) compared to the negative control (NC) group. The intraperitoneal glucose tolerance test and area under the curve analysis revealed insulin resistance in the NC group, which was alleviated by APH supplementation. APH supplementation reduced hepatic gluconeogenesis and increased glucose utilization in the liver and muscle. Furthermore, APH supplementation improved hepatic steatosis by reducing the hepatic fatty acid and phosphatidate phosphatase activity while increasing the hepatic carnitine palmitoyltransferase activity. Furthermore, in the APH supplementation groups, the red blood cell (RBC) thiobarbituric acid reactive substances and hepatic H₂O₂ levels decreased, and the RBC glutathione, hepatic catalase, and glutathione peroxidase activities increased. CONCLUSIONS: APH supplementation reduced visceral fat accumulation and alleviated obesity-related metabolic diseases, including insulin resistance and hepatic steatosis, in aged mice. Therefore, high-quality animal protein APH that reduces the molecular weight and enhances the protein digestibility-corrected amino acid score has potential as a dietary supplement for healthy aging.

Polycythemia vera (PV) is a rare myeloproliferative disease that causes elevated absolute red blood cell (RBC) mass due to uncontrolled RBC production. Moreover, this condition has been associated with a high risk of ischemic stroke and large vessel stenosis or occlusion, with many studies reporting cerebral infarction in PV patients. Despite these findings, there have been no reports on the vessel wall MRI (VW-MRI) findings of the narrowed vessels in PV-associated ischemic stroke patients. To the best of our knowledge, this is the first report in English regarding the carotid VW-MRI findings of a 30-year-old male diagnosed with PV after being hospitalized due to stroke.

Juvenile Paralichthys olivaceus (mean length $17.3{\pm}2.2cm$, mean weight $46.5{\pm}6.3g$) were exposed for 10 days to tributyltin (TBT) at various concentrations (0, 1, 2, 4 and $8{\mu}g/L$). Hematological parameters, such as red blood cell (RBC) count, hematocrit (Ht), and hemoglobin (Hb) concentration, were considerably decreased by high TBT concentrations. In plasma constituents, inorganic components such calcium and magnesium were also significantly altered. Plasma calcium was notably decreased, whereas plasma magnesium was increased. The enzyme components, glutamic oxalate transaminase (GOT) and glutamic pyruvate transaminase (GPT), were significantly decreased by TBT exposure. The present findings suggest that TBT exposure can cause significant alterations in hematological parameters and plasma constituents of flatfish Paralichthys olivaceus.

Objectives : This study was performed in order to investigate the effect of Panax notoginseng(SCG) on phenylhydrazine (PHZ)-induced hemolytic anemia in rats. Materials and Methods : Rats were divided equally into 3 groups (Normal, Control, SCG). Anemic model rats (Control, SCG) were induced by the treatment of PHZ (40mg/kg/day, i.p.) for 3 days. Red blood cell, hemoglobin, reticulocyte count, mean corpuscular volume, mean corpuscular hemoglobin, and mean corpuscular hemoglobin concentration were determined on days 0, 4, 7 and 10. Body weight was investigated on days 0, 2, 4, 6, 8, 10 and weight of spleen was measured on day 10. Results : In the SCG group, significantly higher levels of RBC was found on day 4 and higher concentration of Hb on days 4, 7 and 10. Furthermore, reticulocyte count was dramatically lower on day 10 compared to the control group. Conclusions : These results suggest that SCG may be beneficial in the treatment of hemolytic anemia.

After invasion of red blood cells, malaria matures within the cell by degrading hemoglobin avidly. For enormous protein breakdown in trophozoite stage, many efficient and ordered proteolysis networks have been postulated and exploited. In this study, a potential interaction of a 60-kDa Plasmodium falciparum (Pf)-heat shock protein (Hsp60) and Pf-calpain, a cysteine protease, was explored. Pf-infected RBC was isolated and the endogenous Pf-Hsp60 and Pf-calpain were determined by western blot analysis and similar antigenicity of GroEL and Pf-Hsp60 was determined with anti-Pf-Hsp60. Potential interaction of Pf-calpain and Pf-Hsp60 was determined by immunoprecipitation and immunofluorescence assay. Mizoribine, a well-known inhibitor of Hsp60, attenuated both Pf-calpain enzyme activity as well as P. falciparum growth. The presented data suggest that the Pf-Hsp60 may function on Pf-calpain in a part of networks during malaria growth.

This paper describes a resonant driving piezoelectric micro cantilever practicable to ultrasound thrombolysis device for the treatment of ischemic stroke. The proposed piezoelectric cantilever was designed to be a unimorph structure of Si/$SiO_2$/Ti/Pt/PZT/Pt, and fabricated by top-down sequence etching process. The red blood cell (RBC) lysis experiment was carried out to confirm the usability of the proposed cantilever. Total 87.76 % of RBCs were ruptured using the ultrasound generated by up-down actuations of the fabricated cantilever with AC voltage having the frequency of 19.36 Hz and the magnitude of $30V_{p-p}$.

The study investigated the changes in growth performance, hematological parameters, plasma components, and stress indicators of juvenile starry flounder, Platichthys stellatus, depending on varying exposure to hexavalent chromium. P. stellatus was exposed to waterborne chromium at 0, 50, 100, 200, and 400 ppb for 4 weeks. The result showed that Cr exposure resulted in decreased daily length gain (DLG), daily weight gain (DWG), condition factor (CF), and hepatosomatic index (HIS) in P. stellatus. In terms of hematological parameters, red blood cell (RBC) count, hematocrit (Ht), and hemoglobin (Hb) significantly decreased at 400 ppb after 2 weeks. In terms of plasma components, inorganic analysis was unchanged and cholesterol, an organic component, considerably increased at 400 ppb after 4 weeks. Plasma enzyme components including glutamic oxalate transaminase (GOT) and glutamic pyruvate transaminase (GPT) were significantly increased. Stress indicators such as cortisol and glucose were notably increased over 100 ppb after 4 weeks with increasing chromium concentration. The results indicate that exposure to waterborne Cr induced toxic effects on growth, hematological parameters, plasma components, and stress indicators.

The liver is one of the most common sites of cancer in the world, hepatocellular carcinoma (HCC) predominating. HCC is the sixth most common cancer and the third leading cause of cancer related death overall. Hepatitis C is a major risk factor and HCV is a rapid spreading virus which has become a problem globally, including in Pakistan. Interferon alpha therapy is used against HCV disease to regulate cell reproduction and to boost the immune system. In minute amounts interferon alpha is produced naturally by the immune system in HCV patients in response to hepatitis C virus and binds to receptors in the target cells and starts transcription of 20-30 genes due to which it develops an antiviral influence. Interferon is also administered artificially to overcome HCV disease and remove the biological effect of the virus from the infected site. The use of interferon or Peg-IFN plus Ribavirin treatment is also associated with adverse effects on body. For the current study, a convenient sample of 156 HCV positive patients of both males and females were taken. To collect blood CP and ALT, a reduction of level data and other important information were collected from the patients at regular intervals. Findings were 11.4 % in the red blood cells (RBC), 9.64 % in the total leukocyte count (WBC), 8.4 % in the hemoglobin levels (HB), 30.3 % in the platelet (Plt) count in both sexes. There was significant reduction in ALT levels due to Pegylated interferon plus ribavirin therapy. Hence strict haemotological monitoring of blood CP and ALT levels is necessary at regular intervals to reduce severe side effects which may lead to morbidity and mortality.
