The purpose of this study was to investigate the effects of a butanol fraction of fraction of Alisma canaliculatum All. Braun et Bouche (Ac), and of selenium (Se), on plasma gllucose and lipid levee in streptozotocin (STD-induced diabetic rats. Male Sprague-Dawley rats, fed the AIN-93 recommended diet, were divided into five groups: a non-diabetic control group (no STZ treatment), and four 572-induced diabetic groups which consisted of a diabetic-control group, an Ac-treated group, an Ac-Se treated group, and a Se-treated group. Diabetes was induced in the rats by an injection of STZ into the tail vein at a dose of 45 mg/kg body weight. The butanol (BuOH) fraction of Ac was orally administered at a rate of 400 mg/kg body weight for 21 days to both the Ac and Ac-Se groups. The supplementation of selenium in the Se and Ac-Se groups was achieved by adding (freshly, every day) 2 mg of Se as Na$_2$SeO$_3$ per kg of feed. The rats'body weights and hematocrit (Hct) levels were measured, along with plasma levels of glucose, insulin, cholesterol, HDL-cholesterol, triglyceride (TG), and free fatty acids (FFA). Aminotransferase activities were also analyzed. The non-diabetic rats gained weight, while the diabetic rats lost weight - except in the Ac-Se group, which maintained their initial weight. The blood glucose levels of the Ac group and the Se group were significantly lower than for the diabetic-control group. The plasma triglyceride levels were lowered when both Ac and Se were administered to diabetic rats. The concentrations of plasma FFA in the Ac-Se group were significantly lower compared with the diabetic-control group. Plasma cholesterol levels and alanine aminotransferase activity in the Ac, Ac-Se, and Se groups were significantly lower when compared with the diabetic-control group. Aspartate aminotransferase activity was significantly lower in the Se group compared to the other diabetic groups. These data show that treatment with a butanol fraction of Ac in combination with Se has no synergistic effect. Plasma glucose levels tended to be low when Se was administered to diabetic rats. Supplementation of Se in diabetic rats did not elicit a significant increase in plasma insulin levels or result in hypolipemic effects.

The purpose of this study was to investigate the effect of chloroform(CHC1$_3$) fraction of Alisma canaliculatum All. Braun et Bouche(Ac) with selenium(Se) on the plasma glucose and lipid levels in streptozotocin(STZ)-induced diabetic rats. Male Sprague-Dawley rats were divided into five groups. The normal and diabetic rats were separated into four groups: the STZ-control group, the Ac group, the Ac-Se group and the Se group. Diabetes was induced in the male rats by an injection of STZ into the tail vein at a dose of 45 mg/kg. The CHCl$_3$fraction of Ac(250 mg/kg) was administered orally for 14 days. The supplementation was achieved with the AIN-93 recommended diet by adding 2 mg/kg diet of selenium as Na$_2$SeO$_3$. which was prepared freshly everyday. The body weight, hematocrit(Hct), glucose, insulin, cholesterol, HDL-cholesterol, triglyceride(TG) and free fatty acids(FFA) concentrations in plasma were measured. The aminotransferase activities were also analyzed. The changes of body weight in the experimental groups were not significantly different from that of the STZ-control group, but diabetes hyperphagia accompanied changes with body weight loss in Ac-Se group. The levels of Plasma cholesterol were not significantly different among the experimental groups. The concentrations of FFA in the Ac-Se group increased significantly compared with the STZ-control group. The effect of Se alone significantly increased aspartate aminotransferase activity and alanine aminotransferase activity. The results showed that the treatment of CHCl$_3$fraction of Ac in combination with Se has no synergistic effect. There was a tendency for the plasma glucose levels to decrease when Se was administered into diabetic rats. Supplementation of Se in diabetic rats did not elicit a significant increase in plasma insulin levels and exhibited hypotriglyceridemic effect.

Objective : We examined the putative association between the psychological symptoms and hypoxemia in hospitalized pneumoconiosis patients. Methods : One hundred and nine hospitalized pneumoconiosis patients were divided into two groups according to their level of hypoxemia (PaO2); hypoxemic group consisted of 47 patients with PaO2 lower than 80 mmHg, and comparative group consisted of 62 patients with higher than 80 mmHg. All of them were interviewed with the Hamilton Depression Rating Scale (HAM-D), and completed the Symptom Checklist-90items-Revised (SCL-90-R) and the State-Trait Anxiety Inventory (STAI). The medical data (PaO2, PaCO2, Hb, and Hct), number of hospital days and socio-demographic data as well as scores of the three psychological measurements were compared between the two groups. Results : Hypoxemic patients with lower PaO2 showed higher scores in the HAM-D (p=0.01) and stateanxiety subscale of the STAI (p<0.05). Values of hemoglobin and hematocrit were negatively correlated with levels of trait-anxiety (p<0.05). Thirty patients (27.5%) of total subjects suffered from depression (higher than 18 in the HAM-D), and 46.8% of hypoxemic patients were depressed, whereas 12.9% of comparative group patients were depressed (p=0.01). Conclusion : These results suggest that depression and anxiety might be associated with the hypoxemic mechanism in pneumoconiosis patients.

The objective of this study was to evaluate the effect of spent mushroom substrate (SMS) derived from Pleurotus eryngii on the hematological and biochemical blood properties of elk. A total of 18, two and three-year-old elk were fed three different levels of SMS (0, 15 and 20%) in a corn-wheat bran diet for 80 days. The results indicated significantly high levels of blood monocytes, hemoglobin (Hb), and hematocrit (HCT) in elk fed 15% or 20% SMS (p<0.05) compared to control animals. Serum blood urea nitrogen (BUN) and glucose concentrations were also significantly elevated in elk fed both 15% and 20% SMS. The inclusion of SMS in the elk diet did not affect serum total cholesterol, triglyceride, or low density lipoprotein (LDL)-cholesterol concentrations; however, high density lipoprotein (HDL)-cholesterol concentration was significantly increased in SMS-fed groups. In addition, 20% SMS in the diet increased serum iron and testosterone concentrations in elk. These results indicate that adding SMS to the diet of elk can increase their Hgb, serum BUN, glucose, and HDL-cholesterol concentration; therefore, diets containing SMS may enhance the physiologic condition of elk during growth.

This study was carried out to evaluate the effects of Dochetang for the treatment of chronic diarrhea in a 4 months-old-female Korean native calf. The calf was presented to the Wow Animal Clinic, Iksan with the history of chronic diarrhea for several weeks. The feces test did not reveal the presence of the parasites or microbes causing diarrhea in calf. The blood test was also negative to the virus that causes of diarrhea in calf. Adminstration of parenteral antibiotics resulted in improvement of the condition temporarily but diarrhea was recurred again after 2-3 weeks. Then the calf was treated with Dochetang administered orally once a day in an empty stomach for 15 days. Feces was significantly reduced in moisture on 7 days after initial treatment. On 9 days after initial treatment, the calf had normal appetite and defecation in physiological conditions. Blood samples were collected before administration and on 1, 2 and 3 weeks after initial administration of Dochetang for hematology and biochemistry. A significantly differences were observed in the white blood cell (WBC), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular hemoglobin concentration (MCHC), albumin (ALB), glutamic pyrubic transaminase (GPT), inorganic phosphorus (IP) and magnesium (Mg), while no significant differences were seen in the red blood cell (RBC), hemoglobin (Hb), hematocrit (HCT), platelet (PLT), glucose (Glu), total protein (T-pro), glutamic oxaloacetic transaminase (GOT), blood urea nitrogen (BUN) and creatine (CRE). This study suggests that Dochetang administration can be a successful alternative therapeutic agent in instead of antibiotics for the treatment of chronic diarrhea in calves.

This study was designed to examine the effects of sea buckthorn (SBT) on the plasma blood glucose and cholesterol level in diabetic rats. Diabetes mellitus was induced in male Sprague-Dawley rats weighing 200~220 g by an injection of streptozotocin (STZ) dissolved in a citrate buffer into the tail vein at a dose of 45 mg/kg of body weight. Sprague-Dawley rats were fed an AIN-93 recommended diet and the experimental groups were fed a modified diet containing 10% and 20% of SBT powder for 4 weeks. The experimental groups were divided into 6 groups which consisted of normal (N)-control group, N-SBT 10% and N-SBT 20% treated groups, STZ-control, STZ-SBT 10% and STZ-SBT 20% treated groups. The rats' body weight, aminotransferase activities and hematocrit (Hct) values were measured along with plasma levels of blood glucose and cholesterol. Body weight losses were observed by diabetic groups While the nondiabetic rats gained weight. There were significant differences between the control group and the diabetic groups in the weight of kidney. Aspartate aminotransferase activity was lower in the non-diabetic group compared to diabetic experimental groups. The blood glucose were significantly decreased in the 10% SBT of diabetic group. The cholesterol level of STZ-SBT 10% and STZ- SBT 20% were significantly lower than for the STZ-control group. These results show that the supplementation of sea buckthorn leave powder may have favorable influence on reducing blood glucose and cholesterol level in STZ-induced diabetic rats.

Literature suggests that iron deficiency anemia is prevalent among pregnant women all over the world. This study was designed to evaluate the iron status of pregnant women during the fist five months, with the intention of determining ways to reduce the prevalence of iron deficiency anemia among pregnant women in Korea. We collected dietary information and measured the biochemical status of iron in 171 pregnant women over 16 weeks of gestation (=16.7$\pm$2.34 week). Dietary intakes for 3 days were collected using the 24 hour recall and food record methods. The daily Fe intake was measured using the food frequency method. The Body Mass Index (BMI), calculated by using the pre-pregnancy weight and height, indicated that 31.3% of subjects were under-weight. We divided the subjects into normal and anemic group by using the serum ferritin levels. It appeared that the mean dietary intake of iron was 52.3% of the recommended level for pregnant women. The dietary quality evaluation showed that pregnant women ate only 58% of the recommended amount in the food groups of meat, fish, eggs, beans and milk and dairy products. The hematological indices showed that the mean Hemoglobin (Hb) was 11.9 g/dl, Hematocrit (Hct) was 35.1%, ferritin was 23.9 $ng/ml$, and transferrin was 297.3 ${\mu}g/dl$. The dietary intake of iron was significantly lower and the vitamin C intake was significantly higher in the anemic group. The pre-pregnancy BMI was significantly lower in the anemic group. Variables affecting iron intake were the Fe intake frequency index and the food group score. The Fe index showed significantly positive correlation with the pre-pregnancy food intake and the food group score. Hb showed a significantly positive correlation with the pre-pregnancy food intake. We concluded that strategies to improve iron status be implemented in the pre-pregnant stage so as to reduce the prevalence of iron deficiency and that we should stress on the importance of an adequate diet as well as the maintenance of a heathy weight.

This study was designed to know the effect of kimchi on the hematological and immunological parameters in vivo and in vitro, respectively. To study the effects of kimchi on the hematological parameters, rats(S.D., male) were divided into 4 groups and fed diets containing of 3%, 5% and 10% kimchi or kimchi free diet(control) for 6 weeks. The results of CBC(complete blood cell) tests obtained from the bloods of rates were as follows ; In 10% kimchi group, the level of WBC(white blood cells), RBC(red blood cells), Hgb(hemoglobin), Hct(hematocrit) were increased significantly than those of control group(p<0.05). MCV(mean corpuscular volume), one of the red cell indices, was also increased significantly in the animals fed 10% kimchi(p<0.05). RDW(Red cell distritution width) and PCT(plateletcrit) was lowest in 10% kimchi group(p<0.05). To examine the effects of kimchi on immune cell growth in vitro, three types of mouse immune cells-spleen cells, bone marrow cells, thymus cells-were cultured with extracts of salted Chinese cabbage, fresh kimchi and fermented kimchi(for 1 week) for 12 or 20 days. Control was supplemented with PBS(phosphate buffer saline) excluding kimchi extract. The results of spleen cell, bone marrow cell, and thymus cell cultures showed similar tendency: control medium accelerated death of cells, extracts of salted Chinese cabbage reduced the rate of cell death, and extracts of fresh kimchi and fermented kimchi promoted cell growth. From these results, it could be suggested that kimchi possibly has an effect on the hematopoietic ability and increases immune cell development and growth in vivo.
