Experiments were performed on mice to investigate the effect of methionine diets (MET) on the immunotoxicity of ethanol. ICR female mice were divided into 5 groups, Met (Basal (B)+0.19% methionine(M), B+1.71% M and B+5.13%W) and ethanol(4%) were administered ad libitum for 21 days. The mice were evaluated for changes in immune status as measured by antibody titer, Arthus reaction, delayed type hypersensitivity (DTH), rosette forming cell(RFC) and plaque forming cell (PFC) to sheep red blood cells (S-RBC). To investigate the change of the non-specific immune response, the number of leukocytes in peripheral blood and phagocyte activity were measured. The results were summarized as follows: (1) The weight ratios of spleen and thymus to body weight were significantly increased by the B+0.19% M, B+0.57% M and B+1.71% M groups in comparison with control group(B), but B+5.13% M group was significantly decreased. (2) Humoral immune responses were significantly increased by the B+0.19% M and B+0.57% M groups in comparison with control group, but B+5.13% M group was significantly decreased. (3) Cellular immune responses were significantly decreased by the B+1.71% M and B+5.13% M groups in comparison with control group. (4) Phagocyte activities were significantly increased by the B+0.19% M, B+0.57% M and B+1.71% M groups in comparison with control groups, but B+5.13% M group was significantly decreased. (5) The number of circulating leukocyte was significantly increased in the B+0.19% M and B+0.57% M groups in comparison with control group, but B+5.13% M group was significantly decreased.
Introduction The effects of Bojungikkitang on the immunosuppression induced by methotrexate in rats were investigated in this experiment. The multiple parameters of immunity assessed in. each rats includes the rate of body weight loss, weight changes in thymus, spleen and axillary lymphnode. The number of lymphocyte and CD4+ T cell count in blood, thymus, spleen and axillary lymphnode were also measured. Methodology Male Sprague-Dawley rats were chosen as an experiment object and were divided into 3 groups by a random selection. Each group consisted 6 rats. The normal group didn't receive any treatment. The control group was administered methotrexate for 4 days. The sample group was administered with both Bojungikkitang and methotrexate for 4 days. The dosage of medication was 2cc/day, 1cc given at 10AM and another 1cc given at 5PM. Results The rate of body weight loss was significantly decreased in the sample group. The weight of thymus was significantly increased in the sample group while the weight of spleen did not show much increase. Blood CD4+ T cell count, thymus lymphocyte count, thymus CD4+ T cell count, spleen lymphocyte count, spleen CD4+ T cell count and axillary lymph node CD4+ T cell count were significantly increased in the sample group while blood lymphocyte count and axillary lymphnode lymphocyte count did not show much increase. Conclusion As one can witness from the above results, administration of Bojungikkitang played potent role in increasing immune system among the rats treated with methotrexate which induces immunosuppression. Overall increase of lymphocyte count and CD4+ T cell count in the sample group with Bojungikkitang effectively proves its ability to boost the immune system.

This study evaluated the effects of milk fermented with Pediococcus acidilactici strain BE and Pediococcus pentosaceus strain M103 on diabetes in rats (Rattus norvegicus). The bacteria were separately used as starter cultures for milk fermentation, and the products were then fed to diabetic rats for 15 days. Blood glucose levels, immunohistochemical and histological indicators, lipid profiles, and total lactic acid bacterium counts were evaluated before and after treatment. The administration of milk fermented with P. acidilactici strain BE reduced blood glucose levels from 410.27±51.60 to 304.07±9.88 mg/dL (p<0.05), similar to the effects of metformin (from 382.30±13.39 mg/dL to 253.33±40.66 mg/dL, p<0.05). Increased insulin production was observed in diabetic rats fed milk fermented with P. acidilactici strain BE concomitant with an increased number and percentage area of immunoreactive beta-cells. The structure of insulin-producing beta-cells was improved in diabetic rats fed milk fermented with P. acidilactici strain BE or metformin (insulin receptor substrate scores of 5.33±0.94 and 3.5±0.5, respectively). This suggests that the administration of milk fermented with P. acidilactici BE potentially reduces blood glucose levels and improves pancreatic beta-cell function in diabetic rats.

Background and Objectives: Allergic rhinitis is an allergic reaction characterized by sneezingm itchy nose, mouth and throat, congestion and/or nasal discharge. The offending allergenes are usually pollens, molds, dust mites and animal allergen. Recently, the incidence of infectious nasal diseases tend to decrease. However, allergic rhinitis has increased and treatment in most cases has only deat with the symptom. Tongkyu-tang was composed of sixteen crude drugs. The Oriental Medical References mention therapeutic effects of Tongkyu-tang on nasal obstruction, watery nasal discharg. And Tongkyu-tang has clinically been used for the treatment of common cold, headache, sternutation, rhinitis etc. Speacially Tongkyu-tang is one of the most frequently used medical treatment for the allergic rhinitis. Experimental studies were conducted to investigate for the effect of Tongkyu-tang on the changes of neutrophil segment, lymphocyte, total IgE and nassal tissue in allergic rhinitis of ovalbumin-inhalation rat. Meterial and Methods: Fifteen Sprague-Dawley rats were divided into three group: normal group, control group, experimental group. To induce the allergic rhinitis in control group and experimental group, rats were sentitized intraperitoneally with 0.1 % ovalbumin solution 3 times at intervals of I week. Then intranasal sensitization was performed by diffusing 0.1 % ovalbumin solution 3 times at intervals of 2 days. After that time, rat in the experimental group were oral administration treated by Tongkyu-tang for 28 days. We observed changes in nasal tissue; changes in the number of white blood cell, red blood cell and total Ig E; also changes in the segment of neutrophil and lymphocyte in blood. And we observed the changes of AST, ALT of three group. We used anova test statistically. Result: The number of leucocyte remained unchanged between three group. The number of erythrocyte was increased in experimental group and control group when compared with the normal group. The segment of neutrophil, in blood was decreased in experimental group when compared with the control group but, that was not significant statistically(p<0.05). The promotion of lymphocyte in blood was significantly decreased in experimental group when compared with the Control group(p<0.05). Total IgE was decreased in experimental group when compared with the control group but, that was not significant statistically(p<0.05). The cilium be well preserved in experimental group: the nasal tissue in experimental group was similar to in the normal group. Congestion and expantion of grandular cell in nasal submucosa, hypertropy of epithelium in nasal mucosa, acid mucus in epithelium and neutral mucus in subepithelium were decreased in experimental group when compared with the control group. Effect of Tongkyu-tang on the liver function were also studies in rats. Treatment of Tongkyu-lang did not affected on AST and ALT. Conclusion: Considering the above experimental results, it is suggested that oral administration treatment using Tongkyu-lang, without worry about liver function injury, decreased response on an Animal model with Allergic Rhinitis.

Significant evidence supports the role of the vestibular system in the regulation of blood pressure during postural movements. In the present study, the role of the vestibulo-spino-adrenal (VSA) axis in the modulation of blood pressure via the vestibulosympathetic reflex was clarified by immunohistochemical and enzyme immunoassay methods in conscious rats with sinoaortic denervation. Expression of c-Fos protein in the intermediolateral cell column of the middle thoracic spinal regions and blood epinephrine levels were investigated, following microinjection of glutamate receptor agonists or antagonists into the medial vestibular nucleus (MVN) and/or sodium nitroprusside (SNP)-induced hypotension. Both microinjection of glutamate receptor agonists (NMDA and AMPA) into the MVN or rostral ventrolateral medullary nucleus (RVLM) and SNP-induced hypotension led to increased number of c-Fos positive neurons in the intermediolateral cell column of the middle thoracic spinal regions and increased blood epinephrine levels. Pretreatment with microinjection of glutamate receptor antagonists (MK-801 and CNQX) into the MVN or RVLM prevented the increased number of c-Fos positive neurons resulting from SNP-induced hypotension, and reversed the increased blood epinephrine levels. These results indicate that the VSA axis may be a key component of the pathway used by the vestibulosympathetic reflex to maintain blood pressure during postural movements.
Background: Metastasis and recurrence of primary cancer are the main causes of cancer mortality. Disseminated tumor cells refer to cancer cells that cause metastasis from primary cancer to other organs. Several recent studies have suggested that circulating tumor cells (CTCs) are associated with the clinical stage, cancer recurrence, cancer metastasis, and prognosis. There are several methods of isolating CTCs from whole blood; in particular, using a membrane filtration system is advantageous due to its cost-effectiveness and availability in clinical settings. In this study, an animal model of lung cancer was established in nude mice using the human large cell lung cancer cell line H460. Methods: Six-week-old nude mice were used. The H460 lung cancer cell line was injected subcutaneously into the nude mice. Blood samples were obtained from the orbital area before cell line injection, 2 weeks after injection, and 2 weeks after tumor excision. Blood samples were filtered using a polycarbonate 12-well Transwell membrane (Corning Inc., Corning, NY, USA). An indirect immunofluorescence assay was performed with the epithelial cell adhesion molecule antibody. The number of stained cells was counted using fluorescence microscopy. Results: The average size of the tumor masses was 35.83 mm. The stained cells were counted before inoculation, 2 weeks after inoculation, and 2 weeks after tumor excision. Cancer cells generally increased after inoculation and decreased after tumor resection. Conclusion: The CTC detection method using the commercial polycarbonate 12-well Transwell (Corning Inc.) membrane is advantageous in terms of cost-effectiveness and convenience.
This experiment was done to investigate the effects of GAMIKWYBICHONGTANG(GKCT) on the blood and brain tissues of aged rats. The experimental groups were divided into three groups and treated as follows for ten days before administration of scopolamine ; Non treated group(Normal), Distilled water feeding group (Control), GKCT feeding group(GKCT). After feeding them each, Control and GKCT were injected scopolamine for 5 days.We examined the changes of blood cell(WBC, RBC, platelet), blood serum(BUN, creatinine, glucose, uricacid), erythrocyte hemolysis, the activities of cholinesterase, and measured the amounts of malondialdehyde of the blood serum and checked the activities of catalase, SOD of the brain tissues.The results were as follows;1. GKCT showed significant increase of the number of WBC, but those of RBC and platelet didn't significantly changed in comparison with Control.2. GKCT showed significant decrease of BUN, creatinin, glucose, uric acid in blood serum in comparison with Control.3. Erythrocyte hemolysis were decreased significantly in GKCT in comparison with Control.4. About the activity of cholinesterase of blood serum, GKCT showed no significant increase in comparison with Control.5. In TBA reaction to measure the amount of MDA, oxidant material of blood serum of rats, GKCT showed significant decrease in comparison with Control.6. About the activity of catalase of brain tissue, GKCT showed no significant change in comparison with Control.7. About the activity of SOD of brain tissue, GKCT showed significant increse in comparison with Control.According to the above results, GKCT can reduce the formation of free radical and the accumulation of antioxidant materials, it is suggested that GAMIKWYBICHONGTANG(GKCT) has some effects on antiaging. It is also needed more following studies.
Blood products (BPs) can only be obtained through blood donation and hence represent a finite resource. BPs should therefore be used conservatively. However, BPs are being used indiscriminately without evidence. The purpose of this study was to evaluate the reasons for the use of BPs and their appropriateness. The investigation was carried out based on hemoglobin levels. Data were obtained from Nov 1, 2020, to Oct 31, 2021, from a hospital's OCS/EMR systems. The BPs were dispensed in 21,303 cases, and the number of hemoglobin levels >7.0 g/dL or higher among red blood cell drugs used by each treatment department was 1,173 (>7.0 g/dL). The misuse of blood transfusions is increasing social costs, with the adequacy of transfusion becoming increasingly important. Hence, each medical institution should review the transfusion guideline evaluation index, check the status of the release of BPs, and institute educational programs covering transfusion guidelines and continually evaluate their adequacy.
Objective : This study has been carried out to understand the effect of several herbal medicine concentrated solution on the hyperglycemic mice Induced with streptozotocin(STZ). Methods : The 60 mg/kg of STZ injection into mice twice by 24 h interval and then 120 mg/kg of STZ injection again 3 days after the earlier injection. Control group was subjected to natural recovery, however, treated groups were fed 0.2 ml of several herbal medicine-concentrated solution (PA (x2, several herbal medicine-concentrated solution 1 group); PB (x4 several herbal medicine-concentrated solution 2 group) daily for 6 weeks. Result : The weight of PA was higher than that of control, but weight of PB was lower than control. The blood level of control increased continuously, reaching to 350mg/dL after 6 weeks, however, PA and PB showed a fast reduction of blood glucose. In blood glucose tolerance test, PA and PB showed better resistance than control. The GOT level in significantly(p<0.05) decreased in PA and PB compared with control group. The BUN and creatinine levels are significantly(p<0.01) decreased in PA compared with control group. Feeding of several herbal medicine-concentrated solution in a concentration of PA had an efficient effect on regeneration or recovery of Langerhans islet and ${\beta}-cell$ damaged by STZ. More Langerhans islet and high insulin-immunohistochemical resistance were observed in PA compared with control, but they were higher in PB than in PA. The number of Langerhans islet ${\beta}-cell$ and Langerhans islet. Conclusions : The result from the six weeks of observation demonstrates that the several herbal medicine concentrated solution have a positive effect of lowering the level of blood sugar and they increased insulin concentration. They have an effect for recovery of pancreas tissue and recovery of kidney, liver function from a diabetes mellitus.
The present study was conducted in order to get the relationship of heartworm, Dirofilaria immitis and eosinophils in blood of Jindo dogs.
