Objective : Anticancerous and host safety effects of the combination of Astragali Radix and chlorambucil are studied when it is applied to leukemia cell(P388D1 cell) related disease. Methods : After 5 groups of mice are treated by respective procedures (HG, CHL, HG+CHL, etc), the quantitative analyses (cell proliferation assay, mutagenesis test, survival rate, weight shift observation, tissue and blood analyses, etc) are conducted. Results : While sole injection of Astragali Radix extends the survival period and deter the liver and marrow function deterioration, combined injection (HG+CHL) shows more strong anticancerous effect than sole injection of Astragali Radix or Cholrambucil, and also does not cause any mutation on the normal cells and virulence on marrow and liver caused by leukemia. Conclusions : The combined application of Astragali Radix and chlorambucil has more effective anticancerous and host safety effects than independent use of them.

$^{99m}Tc-galactosyl$ human serum albumin (Tc-GSA) is a radiopharmaceutical that binds to asialoglycoprotein receptors, which are specifically present in the hepatocyte membrane. Because these receptors are decreased in hepatic parenchymal damage, the degree of Tc-GSA accumulation in the liver correlates with findings of liver function test. Hepatic images were performed with Tc-GSA in patients with acute hepatic dysfunction by Amantia Subjunquillea poisoning, and compared with these of liver ultrasonography (USG). Tc-GSA (185 MBq, 3 mg of GSA) was injected intravenously, and dynamic images were recorded for 30 minutes. Time-activity curves for the heart and liver were generated from regions of interest for the whole liver and precordium. Degree of hepatic uptake and clearance rate of Tc-GSA were generated by visual interpretation and semiquantitative analysis parameters (receptor index : LHL15 and index of blood clearance : HH15). Visual assessment of GSA scintigraphy revealed mildly decreased liver uptake in all of subjects. The mean LHL15 and HH15 were 0.886 and 0.621, graded as mild dysfunction in 2, and mild to moderate dysfunction in 1 subject. In contrast, liver USG showed no remarkable changes of hepatic parenchyme. Tc-GSA scintigraphy was considered as a useful imaging modality in the assessment of the hepatic dysfunction.

This study was conducted to investigate the effects of mugwort extracts on the blood ethanol concentration, liver function and low level of cadmuim(Cd) in rats. The effects of mugwort extracts on the blood ethanol concentration was studied in Sprague-Dawley rats (10 weeks old) administered p.o. with 25% ethanol (5g/1kg body weight) and then injected with mugwort extracts (at the 2% levels of daily feed consumption compared with the concentration of catechins level in mugwort extracts) in caudal vein. SD rats were divided into five groups : control group (CON-E, only ethanol and 0.85% saline sol'n treated instead of each extracts), water extracts of mugwort treated to the control (MDW-E), ethanol extracts of mugwort treated to the control (POH-E). And then rat plasma of each time (0hr, 1hr, 2hr, 3hr) was investigated ethanol concentration by gas chromatography. Another rats were measured at the time of 0 and 5hr for the test of GOD(Glutamic Oxaloacetic Transaminase) and GPT(Glutamic Pyruvic Transaminase). Components of each extracts were analyzed by using high performance liquid chromatography. The effects of mugwort extracts on the liver function were studied in culture of rat hepatocyte composed of three groups : Control group and two groups treated with each extracts (1% & 2% MDW, 1% & 2% MOH). Condition of rat hepatocytes cultured for 36hr at $37^{\circ}C$(5% $CO_2$ incubator), number of cells, GOT and GPT activity were investigated. The results obtained were summarized as follows ; 1. Catechins level of mugwort extracts was $8{\sim}10mg/100g(MDW)$, $3{\sim}4mg/100g(MOH)$ 2. The contents of (-)-Epigallocatechin was high in MDW 3. The effects of mugwort extracts on the blood ethanol concentration were as follows; 1) The order in ethanol degradation efficiency was MDW-E > MOH-E > CON-E. 2) Ethanol concentration significantly decreased (p<0.05) in MDW-E and MOH-E. 4. The effects of mugwort extracts on the liver function were as follows; (rat hepatocytes cultured for 36hr at $37^{\circ}C$) 1) Cells condition of MDW-L was better than other groups. 2) The order in number of cells (rat hepatocytes) was 2% MDW-L >1% MDW-L >1% MOH-L > Con-L > 2% MOH-L 5. Cd treatment increased concentrations of hepatic GSH level, and decreased GOT activity in plasma. Therefore, this results suggest that the effects of mugwort extracts may an important rols in degradation ethanol and recovery liver function in body. Also, Mugwort extracts may modify the toxicities of Cd in Cd-treated rats and play an important roles in preventing the liver from various toxicants including Cd in Cd treated rats.

Purpose : To assess the efficacy of recombinant human granulocyte-macrophage colony-stimulating factor(GM-CSF) in the neutropenia by radiotherapy. Materials and Methods : Eleven patients with various solid tumor were treated with a daily subcutaneous dose of GM-CSF(3-7microgram/kg) for 5days during the radiotherapy. Before and during the course of the study all the patients were monitored by the recording of physical examination, the complete blood count with differential and reticulocyte count and liver function test. Eight patients received prior or concurrent chemotherapy. Results : In 10 patients, the neutrophilic nadir was significantly elevated and the lenght of time that Patients had a neutrophil count below $10^3/mm^3$ a threshold known to be critical to acquiring infective complications was shortened following GM-CSF injection. A significant rise (two fold or greater) of neutrophil count was seen in 10 of 11 patients. In most patients, discontinuation of GM-CSF resulted in a prompt return of granulocyte counts toward baseline. However the neutrophil count remained elevated over $10^3/mm^3$ during radiation therapy, and radiotherapy delays were avoided. Other peripheral blood components including monocytes and platelets also increased after GM-CSF treatment. No significant toxicity was encountered with subcutaneous GM-CSF treatment. Conclusion : GM-CSF was well tolerated by subcutaneous route and induced improvement in the neutropenia caused by radiotherapy.

As Kamisipjeondaebotang (KSD) extract is an herbal ingredient, safety is very important due to possible cell poisoning or heavy metal toxicity to organs when administered to humans or animals. Accordingly, this study examined the antioxidant and anti-inflammatory effects of KSD extract to confirm its medicinal safety by using RAW 264.7 cells after heavy metal screening, functional index test of the liver and kidney, and cell survival rate test. Heavy metals were not found in KSD extracts or were less than standard amounts. Liver function indices such as aspartate aminotransferase and alanine aminotransferase revealed low values and kidney function indices such as creatinine and blood urea nitrogen were not significantly different from the normal group. This proved the safety to the human. RAW 264.7 cells showed no poisoning compared to the control group in terms of survival rate. Regarding the antioxidant effect of KSD extract, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and 2,2'-azino-bis(3-ethylbenzothiazo-line-6-sulphonic acid) radical scavenging activity increased at concentrations over $10{\mu}g/mL$. The anti-inflammatory effect of KSD extract significantly decreased based on the amount of nitric oxide at concentrations of 10 and $100{\mu}g/mL$ compared to the control group. Expression of interleukin (IL)-$1{\beta}$ and IL-6 decreased in a concentration-dependent manner. There was no significant difference in tumor necrosis factor-${\alpha}$ level. Based on the results, KSD can be regarded as a safe antioxidant with anti-inflammatory effects for fracture treatment.

The authors conducted a cross-setional study to evaluate the differences of screening test results between clerks and laborers in an occupational health center in Taegu, 1992. A total of 10, 207 workers was included in the study. Of these, male were 6,597 and female 3,610. Constitutional variables included were items of health examination and some confounding variables(sex, age, body weight and work duration). All analyses were conducted separately for each sex through the use of multiple logistic regression analysis on occupation, controlling for age, work duration, and body weight. Laborers showed abnormal hearing test more often than clerks in both sexes. The blood pressure that showed statistical significance in univariate analysis in both sexes lost its significance after controlling covariates. Liver function and urine protein had statistically significant differences between two occupational groups in males and visual correction did in females. The results suggest that there are differences clerks and laborers in some of screening tests and analytic studies are needed to identify the causes of the differences.

Objectives: As Korea transitions into an aging society, the incidence of cerebrovascular disease is expected to increase. Herbal medicine is commonly used in Oriental medicine to treat cerebrovascular disease. However, there is insufficient clinical evidence to actively support the safety of herbal medicine in clinical practice. Therefore, the aim of this study was to determine the toxicity and safety of four herbal medicines (Cheongsimyeonja-tang, Dodam-tang, Hyeolbuchukso-tang, and Boshiniknai-tang) in patients with cerebrovascular disease. Methods: This study used electronic medical records to analyze patients admitted to an oriental medicine hospital from April 1, 2017, to December 31, 2020. Liver and renal function values at the time of admission and discharge were compared. Results: A total of 25 patients were included in this study. We found no significant differences in various variables, such as complete blood count, liver-renal function test, and urine, before and after the administration of the four herbal medicines. Additionally, no significant adverse events related to herbal medicine were observed. Conclusions: This study confirmed the safety of the four herbal medicines in patients with cerebrovascular disease who were hospitalized in a single Oriental medicine hospital.

Antifreeze proteins (AFPs) lower the freezing point but not the melting point of aqueous solutions by inhibiting the growth of ice crystals via an adsorption-inhibition mechanism. However, the function of type IV AFP (AFP IV) is questionable, as its antifreeze activity is on the verge of detectable limits, its physiological concentration in adult fish blood is too low to function as a biological antifreeze, and its homologues are present even in fish from tropic oceans as well as freshwater. Therefore, we speculated that AFP IV may have gained antifreeze activity not by selective pressure but by chance. To test this hypothesis, we cloned, expressed, and assayed AFP IV from cultured subtropical olive flounder (Paralichthys olivaceus), which do not require antifreeze protein for survival. Among the identified expressed sequence tags of the flounder liver sample, a 5'-deleted complementary DNA (cDNA) sequence similar to the afp4 gene of the longhorn sculpin was identified, and its full-length cDNA and genome structure were examined. The deduced amino acid sequence of flounder AFP IV shared 55, 53, 52, and 49 % identity with those of Pleuragramma antarcticum, Myoxocephalus octodecemspinosus, Myoxocephalus scorpius, and Notothenia coriiceps, respectively. Furthermore, the genomic structure of this gene was conserved with those of other known AFP IVs. Notably, the recombinant AFP IV showed a weak but distinct thermal hysteresis of $0.07{\pm}0.01^{\circ}C$ at the concentration of 0.5 mg/mL, and ice crystals in an AFP IV solution grew star-shaped, which are very similar to those obtained from other polar AFP IVs. Taken together, our results do not support the hypothesis of evolution of AFP IV by selective pressure, suggesting that the antifreeze activity of AFP IV may have been gained by chance.

The relationships between subjective symptoms of toluene exposed workers and concentration of their urinary excretion of hippuric acid were investigated. The exposed groups of 146 workers exposed to toluene and the control groups of 47 workers have never been exposed to toluene in Ulsan area were selected and studied. Hippuric acid was measured by HPLC, and counts of blood cells and liver function test were also performed. The mean value of urinary hippuric acid concentration of the control group was 0.322($\pm$0.267) g/L, while that of the exposed group was 1.260($\pm$0.395) g/L. As the concentration of hippuric acid had statistical proximity in $0.1\%$ level, WBC, GOT, and GPT didn't have any proximity(P>0.05). The exposed group showed lower level of leucocyte counts 6522.40(1710.3) than the control group 6891.50(1483.7). The exposed group showed higher level of GOT(25.75), GPT(27.09) than GOT(23.75), GPT(25.21) of the control group. Dried skin was the highest complained symptom of toluene exposed workers, the second strained eye, the third poor auditory function, and the fourth was headache.
