The aim of this study was to investigate the effects of several herbal prescriptions in patients with allergy or atopic disease, such as atopic dermatitis, asthma and allergy rhinitis and others, on the blood immunological parameters and to verify the safety of long-term use of herbal medicine. Eighty one patients with allergy or atopy disease who taken herbal medicine at least for 2 months were compared with patients who taken same medicine with no allergy & atopy disease (n=14) and normal healthy subjects (n=22). According to the comparison of immunological parameters change, the data showed that herbal medicine decreased IgE (P=0.003), Eosinophil ratio (P<0.001) and count (P<0.001) of White Blood Cell (WBC) and did not affect to the liver cell enzymes in blood. This results indicated that herbal medicine decreased immune hypersensitivity and improved chronic inflammation related to blood immunological parameters of allergy or atopy diseases. In addition, herbal medicine seemed to be safe to the liver function for long-term use.

This study aimed to compare a microparticle enzyme immunoassay (MEIA) with a liquid chromatography-tandem mass spectrometry (LC/MS/MS) technique for the measurement of tacrolimus concentrations in adult liver transplant recipients, to investigate how the assay choice influenced the population pharmacokinetics of tacrolimus and to identify patient characteristics that affected pharmacokinetic parameters in each assay. Tacrolimus concentrations from 29 liver (n=52 paired-samples) transplant recipients measured by both MEIA and LC/MS/MS were used to evaluate the performance of these methods in the clinical setting. Tacrolimus pharmacokinetics was studied independently using MEIA and LC/MS/MS data in 70 adult patients using a population approach performed with NONMEM. Patient characteristics which influenced pharmacokinetic parameters in each assay were compared. The relation between LC/MS/MS and MEIA measurements was best described by the regression equation MEIA=1.465*LC/MS/MS-1.336 (r=0.91). Multiple linear regression analysis showed significant inverse relationships between assay difference and hematocrit (Hct) (p<0.025) in liver graft recipients. In MEIA, the population estimate of tacrolimus CL/F and apparent volume of distribution (Vd/F) were found to be 10.1 L/h and 226 L, and in LC/MS/MS, 13 L/h and 305 L respectively. Neither patient's age, weight, gender, grafted hepatic weight, albumin concentration, nor markers of liver function influenced tacrolimus CL/F The final model of CL/F was found to be 10.1+(Hct/Hct mean)$^{12.0}$ in MEIA and 13+(1+Hct/578) in LC/MS/MS indicating that CL/F was influenced by hematocrit.

Background: The diagnosis of esophageal varices (EV) is based on the findings of esophagogastroduodenoscopy (EGD), biopsy, and serum markers. Thus, noninvasive cost-effective tests through which high-risk EV children can be diagnosed are needed. Purpose: This cross-sectional study aimed to identify the noninvasive markers for EV in children with liver cirrhosis. Methods: A total of 98 children with liver cirrhosis were evaluated in this study. The spleen size, platelet count, serum albumin, liver function test results, and risk scores were evaluated prior to endoscopy. The endoscopic investigations aimed to identify the presence of EV and red signs, and determine varices sizes. Results: Endoscopy revealed varices in 43 subjects (43.9%). The spleen size, platelet count, international normalized ratio, aspartate aminotransferase to platelet ratio index (APRI), platelet count to spleen size ratio, and risk score differed significantly between patients with and without EV on univariate analysis; however, the logistic regression analysis showed no differences, indicating that none of these parameters were independently associated with the presence of EV. Conclusion: Platelet count, risk score, platelet count to spleen size, and APRI can be useful tools for the identification of high-risk patients with EV and might reduce the need for invasive methods like EGD.

In this paper the morphological characteristic parameters according to the Lee's physical constitution theory are suggested using the X-ray computed tomography. The Lee's physical constitution theory is classify into 4 physical constitutional types by the relative degree of visceral function: those are macro-negative(strong liver- weak lung), micro-negative(strong kidney- weak spleen), micro-positive(strong spleen- weak kidney) and macro-positive(string lung- weak liver). The morphological characteristic parameters are the following. The AA-line is the distance between Rt. & Lt. acupuncture point keug-cheun. The BB-line is the length of lung. The CC-line is the longest width of thorax. The DD-line is the vertical distance between the CC-line and the EE-line. The EE-line is the distance between the Rt. and Lt. anterior superior iliac spines. As the results macro-negative(strong liver-weak lung) has the longest CC-line and the short BB-line. Micro-negative(strong kidney-weak spleen) has the longest EE-line and the short CC-line. Micro-positive(strong spleen-weak kidney) has the longest DD-line and the short BB-line. And macro-positive(strong lung-weak kidney) has the longest BB-line and the short EE-line.

The objective of this study was to examine the biochemical parameters of hepatic function such as serum level of ALT (alanine aminotransferase), AST (aspartate aminotransferase), ALP (alkaline phosphatase), LDH (lactate dehydrogenase), and content of TG (triglyceride) and cholesterol, and tissue immunological changes of the $CCl_4$-treated rats with administration of the mixed sample extract (MSE). The liver weight in $CCl_4$-administered experimental control group (EC) was slightly higher than that of normal control (NC) group. Hepatic damage parameters (ALT, AST, ALP, LDH & TG) in serum of the EC group were significantly higher than those in serum of the NC and silymarin-treated positive control (PC) group. On the other hand, these hepatic damage parameters of MSE-treated experimental (E1 & E2) groups were significantly lower than those of EC group. The number of WBC, neutrophils, lymphocytes and platelets, and the contents of hemoglobin, and hematocrit in EC group were significantly higher than those of NC group. However, the number of WBC and lymphocytes in E1 and E2 groups were significantly lower than those of EC group. Also, the collagen developmental areas in the liver of NC and PC groups by hepatic immuno-histological findings were found slightly positive. Whereas, hepatic fibrous developmental tissue of EC group was strongly positive brown color band, those of E1 & E2 groups were decreased. Therefore, it was concluded that the induction of hepatic fibrous tissue activation had a preventive effect of MSE against the $CCl_4$-induced hepatic damage in rats. However, further study is needed in this filed.

TCDD 독성이 유발된 흰쥐 혈액의 생화학적 지표에 미치는 상엽 물추출물 (MLE)의 효과를 조사하였고 통계자료는 일원분산분석과 Scheffe의 사후검증을 하였다. TCDD 투여 시 감소했던 백혈구와 혈소판의 수가 MLE투여로 급격하게 회복(p<0.01)되어 면역기능 개선효과가 있었다. TT에 의해 감소했던 혈중 칼슘 및 마그네슘의 농도는 MLE 투여 시 유의하게 증가(p<0.01)하였으나 인의 농도는 TT군에 비하여 MLE군이 유의하게 감소(p<0.01)하였다. 신장 기능과 관련된 creatinine 및 blood urea nitrogen은 TT군과 MLE군 사이에 유의성은 없었으며, 요산은 TT군과 MLE군 모두에서 감소하였다. 한편 TT에 의해 증가했던 glucose 농도, amylase 및 lipase의 효소 활성도는 MLE 투여시 유의하게 감소(p<0.01)하여 혈당상승 억제효과가 있었다. Total protein, ${\gamma}$-GTP 활성은 TT와 MLE의 영향을 거의 받지 않았으나 TT에 의해 증가했던 AST, ALT 및 ALP의 활성도는 MLE 투여 시 모두 유의하게 감소(p<0.01)하여 간기능 개선의 효과가 있었다. 한편 Total cholesterol, triglyceride와 LDL-cholesterol의 경우 TT에 의해 유발된 고지혈 증상이 MLE 투여 시 유의하게 감소(p<0.01)하여 항고지혈 효과가 있었으며 HDL-cholesterol은 TT군과 MLE군 모두에서 증가하였다. 이와 같이 MLE는 TCDD독성이 유발된 흰쥐에서 독성을 완화시켜 주는 작용이 있음을 알 수 있었다.

The purpose of the study was to identify the effect of laser parameters on photocoagulation to maximize safety and efficacy during varicose vein treatment. CW and pulsed modes at 1470 nm were initially compared as a function of power on bovine liver tissue. In the pulsed mode, various parameters including repetition rate, duty cycle, and irradiation time were compared to evaluate tissue response during thermal treatment. The results demonstrated that CW and pulsed modes yielded almost similar coagulation development possibly due to shorter irradiation time of 5 sec. Regardless of laser mode, both repetition rate and duty cycle presented constant coagulation rate whereas longer irradiation time facilitated coagulation process.

This study was conducted to assess the relation between threonine (Thr) oxidation rate and threonine efficiency on rat and chicken fed with graded levels of protein and threonine. The increase in threonine content from 0.28 to 0.72% in a diet containing 12.0% crude protein (CP) caused a gradual increase in threonine dehydrogenase (TDG) activity in rat liver. Similar, but more pronounced results were observed after 18.0% CP in the diet. Both protein levels in combination with the highest level of threonine supplementation increased liver TDG activity significantly, indicating enhanced threonine catabolism. Parameters of efficiency of threonine utilization calculated from parallel nitrogen balance studies decreased significantly and indicated threonine oversupply after a maximum of threonine supplementation. At the lower levels of threonine addition the efficiency of threonine utilization was not significantly changed. In the chicken liver up to 0.60% true digestible threonine (dThr) in the 18.5% CP diet produced no effect on the TDG activity. However, TDG activity in the liver was elevated by the diet containing 22.5% CP (0.60% dThr) and the efficiency of threonine utilization decreased, indicating the end of threonine limiting range. In conclusion, the in vitro TDG activity in the liver of rat and growing chicken has an indicator function for the dietary supply of threonine.
