Objective : The aim of this study is to investigate the inhibitory effect of Injinchunggantang on hepatic sclerosis induced by $CCl_4$. Methods : Weight, liver function test and complete blood cell count, gross findings, and findings on liver tissue of the past(Hematoxylin & Eosin stain, Masson-Trichrome stain) were studied. Results : When it comes to the change of rats' body weight, The $CCl_{4^+}$Injinchunggantang group lost far less weight than The $CCl_{4^-}$only group. In the liver function test, which is focused on various areas such as total cholesterol, alkaline phosphotase, albumin, aspartate transaminase, alanine transaminase, The $CCl_{4^+}$Injinchunggantang group was much more closer to normal limit than the $CCl_4$ only group. In the complete blood cell count, including white blood cell, red blood cell, hemoglobin, hematocrite, platelet, The $CCl_{4^+}$Injinchunggantang group significantly closer to normal limit than $CCl_{4^-}$only group. In the gross findings of hepatic fibrosis models, Injinchunggantang showed inhibitory effect on hepatic fibrosis in the order. In the past findings of hepatic fibrosis models in Hematoxylin & Eosin, Masson-Trichrome staining, the liver in $CCl_{4^-}$only group showed atrophy and necrotic change with white nodules, whereas that of $CCl_{4^+}$Injinchunggantang group showed lesser significant change with the well_preserved tone of the tissue. In the extent of the inhibition of the hepatic fibrosis, the Injinchunggantang group showed statistically significant inhibitory effect(p<0.05) in the sclerosis model. Conclusions : These results show that Injinchunggantang have inhibitory effect on hepatic sclerosis induced by $CCl_4$ and further ultimately prevent liver cirrhosis. To obtain more credible results in this experiment, the invention of a new experimental model more similar to human hepatic sclerosis is still needed.

Objective : This study was conducted to investigate the effect of Mokhyangsaenghwa-tang (MS) and Mokhyangsaenghwa-tang plus Cervi Pantotrichum Cornu (MS-C) on postpartum recovery and lactation. Materials and Methods : We used 18-week pregnant Spraque Dawley rats and administered the decoctions of MS and MS-C to rats once a day for 4 days or 8 days. Then we observed changes in the body weight of pup rats and complete blood cell count, liver function test, renal function test, mammary gland tissue, level of serum prolactin, ${\beta}-casein$ and WAP of postpartum rats. Result : A significant increase in body weight was observed in MS-C treated pup rats compared with in MS treated group. The levels of WBC and platelet from MS group and MS-C group were decreased compared with the control group. The levels of RBC, hemoglobin and hematocrit from MS group and MS-C group showed statistically significant increases compared with the control group. The levels of protein, albumin from MS group and MS-C group were increased compared with the control group. The levels of BUN, creatinine from MS group and MS-C group did not show statistically significant changes compared with the control group. The mammary gland tissues from MS group and MS-C group showed increased angiogenesis. The levels of serum prolactin from MS group and MS-C group were increased compared with the control group. The expression of ${\beta}-casein$ and WAP genes from postpartum rats treated with MS and MS-C was increased. Conclusion : This study shows that MS and MS-C improved postpartum recovery and lactation in rats.

In this study, the clinical safety and toxicology of oral ingestion of supplement capsules containing ginseng radix was investigated in healthy young volunteers. This study was a pilot randomized, double blinded, placebo controlled trial. The healthy volunteers were divided into 6 groups of 20 each (10 males and 10 females). They took the ginseng powder for 35 days (3g/day) for safety evaluation. There were measured general healthy levels such as hematological, biochemical and electrocardiographic parameters. After the first week, besides Korean white ginseng the other treatments led to an significant increase of white blood cells. Korean red ginseng increased UREA (blood urea nitrogen) in healthy volunteers, but it didn't exceed the range of normal values, and in the subsequent process of treatment there is no effect of elevating UREA. After the three weeks, Korean white ginseng showed relatively low the content of blood glucose and low-density lipoprotein cholesterol. After the five weeks, compared with the other treatments, Korean red ginseng increased white blood cells, platelet distribution width and average volume of platelet. Korean white ginseng decreased low-density lipoprotein cholesterol. American ginseng decreased blood creatinine in healthy volunteers. In conclusion, through test the blood routine, urine routine, liver function, renal function, blood glucose, blood lipid and electrocardiogram, the healthy volunteers continuous taking ginseng for 35 days (3 g/day) is safe and reliable, and have no obvious adverse reactions and side effects.

Special anesthetic considerations were required for children with acute or chronic liver disease. We experienced a case of dental treatment to control infection under general anesthesia in the 2-year-old girl with liver failure. She was also scheduled for liver tansplantation. Her preanesthetic results of liver function test, electrolytes, and coagulation panel were unstable and out of normal ranges. Uneventful anesthetic induction using isoflurane and atracurium and nasotracheal intubation were carried out. General anesthesia was maintained with isoflurane for 2 hours. Oozing from multiple extraction sites was sustained, so the transfusion of platelet concentration 1 units, fresh frozen plasma 1 unit, and packed red blood cell 1 unit was done. She was recovered without complication but was transferred to pediatric intensive care unit for wound care with her endotracheal tube kept. She was transferred to a ward without noticeable complications next day. So we report this successful case of anesthetic management for dental treatment in a child with liver failure.
We investigated the effect of mulberry leaf extract (MLE) on blood biochemical parameters of white rats induced TCDD toxicity. Data were analyzed by One-way ANOVA and Post-Hoc Test. The numbers of leukocyte and platelet decreased by TCDD were increased dramatically after treated MLE (p<0.01). The concentration of calcium and magnesium decreased by TT were increased by MLE and shown a statistical significance (p<0.01) but the concentration of phosphorus increased by TT was decreased by MLE. In the test of parameters related to renal function, only the concentration of uric acid in the MLE group was decreased than it in TT group and shown a statistical significance (p<0.01). Also the concentration of blood glucose and the activity of amylase and lipase increased by TT were decreased after treated MLE and shown a statistical significance (p<0.01), and MLE had an control effect for elevating blood glucose. In the test of parameters related to liver function, the acticity of AST, ALT and ALP increased by TT was decreased after treated MLE and shown a statistical significance (p<0.01), and MLE had an improving effect for liver function. In the case of total cholesterol (T,cho), triglyceride( TG), LDL-cholesterol (LDL-C) and HDL-cholesterol (HDL-C) related to lipid metabolism, the amount of T,cho, TG, LDL-C increased by TT were decreased after treated MLE and shown a statistical significance (p<0.01), and MLE had an ability of anti-hyperlipidemia. From these results, we concluded that MLE could mollified TCDD toxicity in white rats exposed to TCDD.
Objectives : The purpose of this study was to investigate the effects of modified fasting therapy on body composition, blood cell count and blood chemistry in inpatients. Methods : The modified fasting therapy program consists of three phases, a period of reducing food intakes, fasting and refeeding. Body weight, body composition, and the degree of obesity were estimated in before fasting therapy and after refeeding. Blood cell count and blood chemistry were estimated in before fasting therapy, before refeeding and after refeeding. Results : After modified fasting therapy, body weight, body fat mass, percent body fat, body mass index(BMI), body matabolic rate(BMR) and muscle mass was decreased significantly. WBC count and platelet count decreased significantly, RBC count and hemoglobin increased significantly and hematocrit was not changed significantly but within normal limit. AST and ALT increased significantly, especially patients group over BMI 25 within normal liver function. This study was not founded correlation between decreased muscle mass and increased liver function test. ALP, BUN, Total-cholesterol, and triglyceride decreased significantly. Creatinine increased significantly, but within normal limit. Sodium was not changed significantly, potassium decreased significantly but within normal limit. Conclusions : These results suggest that modified fasting therapy will be beneficial if several measures complement.
Purpose: Patients who receive frequent blood transfusions are at an elevated risk of developing hepatic fibrosis due to iron overload in the liver. In this study, we evaluated the effectiveness of transient elastography (TE) (FibroScan®) for assessing liver fibrosis in patients with pediatric cancer. Methods: We enrolled 106 consecutive cases of acute leukemia in individuals under 21 years of age. The participants were followed for 2 years. Based on their serum ferritin (SF) levels, the patients were divided into two groups: group 1 (SF≥300 ng/mL) and group 2 (SF<300 ng/mL). A liver FibroScan® was performed, and a p-value of less than 0.05 was considered statistically significant. Results: Among the various parameters in the liver function test (LFT), alkaline phosphatase was significantly higher in a subgroup of patients aged 5-8 years in group 2 compared to those in group 1. The indices of liver fibrosis determined by TE, including the FibroScan score, controlled attenuation parameter score, steatosis percentage, and meta-analysis of histological data in viral hepatitis score, as well as indirect serum markers of liver fibrosis such as the aminotransferase (AST)/alanine aminotransferase (ALT) ratio, Fibrosis 4 score, and AST to platelet ratio index, did not differ significantly between the two groups. The association between the TE results and LFT parameters was only significant for ALT. Conclusion: Transfusion-associated iron overload does not have a significant correlation with severe liver fibrosis. FibroScan® is not a sensitive tool for detecting early stages of fibrosis in survivors of pediatric leukemia.
The ultimate objective of periodontal treatment is to stop disease progression and to regenerate destroyed periodontal tissues and thereby regain normal function. Growth factors are naturally found polypetides which stimulate many cellular activities pertaining to wound healing by acting as signal molecule in controlling cell movement, proliferation, and matrix production. Platelet derived growth factor (PDGF) is 28,000-35,000 Da molecular weight dimeric protein with 2 long positively charged polypeptide chains connected by sulfide bonds. The purpose of this study is to evaluate histologically the initial guided tissue regeneration in a periodontal defect f a beagle dog treated with a biodegradable membrane formed with polylactic acid (poly-L-lactic acid) and polyglycolic acid loaded with 200ng/$cm^2$ platelet derived growth factor. 2 beagle dogs were used in he experiment. $5mm{\times}6mm$ alveolar bone defect was formed in upper and lower canines and third premolars and a reference notch was placed. PDGF-BB non-containing membrane was used as control. Each defect was randomly assigned to the test roup or the control group. The dogs were sacrificed 3 weeks after membrane placement. Toluidine blue and multiple staining was done for histological analysis. In the 3 week specimen in the control group, no new one formation could be seen. Small amount f bone resorption below the notch could be seen. In the notch, loose connective tissue with infiltration of inflammatory cells could be seen. Also thin discontinuous new cementum could be seen and the membrane still retained its structure. Where PDGF-BB containing membrane was used, new bone formation could be seen in the notch at weeks and also continuous thin cementum could be seen. PDL cells were observed between new bone and new cementum and some were attached to bone and cementum. These results suggest that new bone and cementum formation seen when PDGF-BB loaded membrane was used was due to inhibition of downgrowth of epithelial cells and also due to continuous release of the growth factor. Further study on the resorption characteristics of the membrane nd the release characteristics of the PDGF-BB is necessary. Also, development of a membrane easier to use clinically is necessary.
Background: c-Kit is a proto-oncogene that encodes a tyrosine kinase receptor (CD117). Mean platelet volume (MPV) is a useful marker for demonstrating thrombocyte function. We aimed to investigate whether c-kit is expressed in benign, preneoplastic and neoplastic endometrial tissues and whether MPV has a relation with c-kit expression and its intensity. Materials and Methods: c-Kit expression was investigated immunohistochemically in 10 samples of normal endometrium (n=10), simple endometrial hyperplasia (5 cases with atypia and 10 cases without atypia), complex endometrial hyperplasia (10 cases with atypia and 10 cases without atypia) and endometrial cancer (EC) (10 cases grade I and 10 cases grade II) and MPV of all cases was checked. Results: c-Kit expression was observed at very low rates in cases with normal endometrial tissues (NE) and in hyperplasia without atypia. c-Kit expression and immunostaining were strong in endometrial atypia and EC. MPV levels of complex atypical endometrial hyperplasia (CAEH) (p:0.002), EC grade I (ECG I) (p<0.001) and EC grade II (ECG II) (p<0.001) were significantly elevated when compared with the NE group. Both c-kit expression and intensity of immunostaining had a positive correlation with MPV level. Conclusions: While c-kit expression and intensity of immunostaining were mildly positive in NE and hyperplasia without atypia, they were clearly observed in EC and hyperplasia with atypia. As c-kit expression is related to the mutagenesis a long-term followup may be needed in these cases. A high MPV level may be a good test for demonstrating c-kit expression and intensity of immunostaining.

Polymorphonuclear leukocytes (PMNs) play an important role in myocardial ischemia/reperfusion (MI/R) injury. Moreover, platelets are also important blood cells that can aggravate myocardial ischemic injury. This study was designed to test the effects of PMNs and platelets separately and together in provoking cardiac dysfunction in isolated perfused rat hearts following ischemia and reperfusion. Additional control rat hearts were perfused with $75{\times}10^6$ PMNs, with $75{\times}10^6$ platelets, or with $75{\times}10^6\;PMNs+75{\times}10^6$ platelets over a five minute perfusion followed by a 75 min observation period. No significant reduction in coronary flow (CF), left ventricular developed pressure (LVDP), or the first derivative of LVDP (dP/dt max) was observed at the end of the observation period in any non-ischemic group. Similarly, global ischemia (I) for 20 min followed by 45 minutes of reperfusion (R) produced no sustained effects on the final recovery of any of these parameters in any group of hearts perfused in the absence of blood cells. However, I/R hearts perfused with either PMNs or platelets alone exhibited decreases in these variables of $5{\sim}10%$ (p<0.05 from control). Furthermore, I/R hearts perfused with both PMNs and platelets exhibited decreases of 50 to 60% in all measurements of cardiac function (p<0.01). These dual cell perfused I/R hearts also exhibited marked increases in cardiac myeloperoxidase (MPO) activity indicating a significant PMN infiltration, and enhanced P-selectin expression on the coronary microvascular endothelium. All cardiaodynamic effects as well as PMN accumulation and P-selectin expression were markedly attenuated by a recombinant soluble PSGL-1 which inhibits selectin mediated cell adhesion. These results provide evidence that platelets and PMNs act synergistically in provoking post-reperfusion cardiac dysfunction, and that this may be largely due to cell to cell interactions mediated by P-selectin. These results also demonstrate that a recombinant soluble PSGL-1 reduces myocardial reperfusion injury by platelet and PMNs interaction.
