The objective of this study was to obtain data on safety-in-use of yeast hydrolysate with a molecular weight of 10~30 kDa as a dietary supplement by assessing its subacute oral toxicity in ovariectomized rats. Yeast hydrolysate did not produce mortality or significant changes in general behavior or gross appearance of internal organs of rats. There were no significant differences in organ weights between control and yeast hydrolysate groups. Hematological analysis and blood chemistry revealed no toxic effects of yeast hydrolysate. Neither gross abnormalities nor histopathological changes were observed. These results show that yeast hydrolysate possesses very low toxicity as indicated in a postmenopausal animal model.

Background : Guillain-$Barr{\acute{e}}$ syndrome(GBS) is characterized clinically by acute flaccid paralysis, areflexia, and albumino-cytologic dissociation. Based on electrophysiology and pathology, GBS can be divided into either predominantly demyelinating or predominantly axonal patterns. Objectives : The clinical and laboratory status of probable acute axonal GBS occurring at a mental hospital was evaluated. Methods : Eight schizophrenia patients with probable acute axonal GBS were analyzed. Results : The mean age of the patients was 38 years old. Most of the patients were men. All patients showed an acute ascending paraparesis and/or quadriparesis with areflexia, and all have a history of schizophrenia for 3~20 years. The diseases occurred predominantly in the summer and electrodiagnostic studies revealed axonal patterns. The patients were treated by supportive care, except one patient with intravenous immunoglobulin. The prognosis was improved in 3 ; no change in 4 and 1 became aggravated. One patient with acute motor-sensory axonal neuropathy had a recurrence after 10 months of the first attack. Conclusions : Axonal GBS has been considered uncommon clinically or electrophysiologically, but 8 probable acute axonal GBSs occurring at a mental hospital have been diagnosed in 3.5 years.

Background: Deep venous thrombosis(DVT) is a curable disease when it is appropriately treated in the early stages of onset. The long term follow up of chronic DVT shows poor prognosis with serious complications such as venous valvular insufficiency, venous claudication, venous ulcer and leg swelling. Thrombolytic therapy is a very active treatment that delivers thrombolytic agents via catheter to the target thrombi. The aim of this study is to evaluate the effect of catheter directed thrombolysis using urokinase to acute DVT. Material and Method: We studied 5 patients, who were diagnosed as acute DVT and had no contraindication for selective hemolysis using urokinase. Result: All the patients were successfully recanalized. Total infusion time of urokinase was 2.0$\pm$0.6 days, and the amount was 5.9$\pm$2.45 million IU. In 4 patients, who were diagnosed as May-Therner syndrome, we performed the balloon angioplasty and inserted the stent at the stenotic portion. There were minor complications such as hematuria, hematoma at puncture site, and all of them are self limited. Conclusion: Catheter induced thrombolysis is an effective treatment in acute DVT.

Postcardiac injury syndrome (PCIS) is an inflammatory process that usually occurs within 1 to 6 weeks after an injury to the pericardium, epicardium, or myocardium. As more interventions are performed for complicated coronary artery obstructive lesions, there have been some recent reports on PCIS following percutaneous coronary intervention (PCI). The medical management of PCIS depends on nonsteroidal anti-inflammatory drugs (NSAIDs), in addition to colchicine or steroids. An 80-year-old male patient underwent a PCI. Unfortunately, the guidewire piercing failed but he showed no immediate signs of complication. However, 5 hours after the procedure, he complained of chest discomfort. An electrocardiogram showed widespread ST elevation. Chest X-ray and computed tomography showed pulmonary congestion with pleural effusion, while thoracic echocardiography showed a moderate amount of pericardial effusion. NSAIDs were initiated, but there was no improvement of symptoms. We describe an unusual case of atypical earl onset PCIS after PCI, recovered rapidly by steroids.

The acute and subchronic toxicity of 1 kGy gamma-irradiated orange was evaluated in ICR mice. For acute toxicity, groups of 30 male and 30 female ICR mice were orally administered 1 kGy gamma-irradiated orange (0, 1,000, and 2,000 mg/kg). The mortality, clinical sign, body weight changes, and necropsy findings of ICR mice were observed for 14 days. No significant changes in body weight or abnormal gross findings were observed in relation to 1 kGy gamma-irradiated orange. Hematological and serum biochemical parameters were within normal ranges. According to the results, 1 kGy gamma-irradiated orange had no special toxic effects in male and female ICR mice at 2,000 mg/kg. For subchronic toxicity, groups of 36 male and 36 female ICR mice were given a diet of 1 kGy gamma-irradiated orange for 13 weeks (control, non-irradiated, and irradiated imported orange). During the experimental period, mortality, clinical signs, body weight change, food consumption, organ weight, and histopathological examination did not show any changes in comparison to the control group. Several hematological and serum biochemical parameters showed statistically significant changes, but these changes were within normal range. These results indicate that 1 kGy gamma-irradiated orange did not cause any toxic effects in male and female ICR mice and therefore can be considered as safe.

We investigated the acute toxicity from a single dose of crude anti-fungal compounds produced by Lactobacillus plantarum AF1, a lactic acid bacterium isolated from kimchi, on ICR male and female mice in vivo. The test article was orally administered once to both sexes of mice. The mortality rate, clinical findings, autopsy findings, and body weight changes were monitored daily for 14 days. In the oral acute toxicity test, male and female mice were gavaged with four doses (5, 50, 300 or 2,000 mg/kg) of the crude anti-fungal compounds. The oral $LD_{50}$ of the crude anti-fungal compounds was higher than 2,000 mg/kg. No significant changes in general conditions, body weights, clinical signs, or appearance of gross lesions were observed. In conclusion, our results suggest a low toxicity and no-adverse-effects from crude anti-fungal compounds produced by Lactobacillus plantarum AF1 up to 2,000 mg/kg via the oral route.

Chickens from 10 to 32 weeks of age were inoculated with P. multocida via seven routs(intravenous, intramuscular, intraperitoneal, subcutaneous, into ear, intranasal, per oral). The development or distribution of disseminated intravascular coagulation (DIC) in multiple organs and the role of P. multocida endotoxins in disease process of fowl cholera were studied. The histological diagnosis of DIC was made by demonstration of fibrinous in arterioles, capillaries, venules and medium-sized blood vessels. The presence of fibrinous thrombi in blood vessels of multiple organs was observed in chickens which died within approximately 3 days post inoculation. Fibrinous thrombi were observed most frequently in the lung(90% of all cases with DIC) followed by liver (70%), kidney (60%), heart(20%), spleen, brain, pancreas, thymus and thyroid gland. The density of fibrinous thrombi (i.e. the number of thrombi per section) was greatest in the lung, followed by spleen, kidney, liver and heart. It is thought that the widespread hemorrhage of acute fowl cholera is also caused by P. multocida endotoxin which initiates DIC in variety of organs. The cause of death for the chickens after infection with acute fowl cholera is probably due to an endotoxin (septic) shock accompanied with DIC in multiple organs.

The $in$ $vivo$ single-dose acute toxicity of $Lactobacillus$ $plantarum$ AF1, a lactic acid bacterium isolated from kimchi, in ICR male and female mice was investigated. The test article was intraperitoneally or orally administered once to both sexes of mice. The motalites, clinical findings, autopsy findings, and body weight changes were monitored daily for 14 days. In the oral acute toxicity test, the male and female mice were gavaged with four doses (5.0, 2.5, 1.25 and 0.625 g/kg) of $Lb.$ $plantarum$ AF1. The oral $LD_{50}$ of the $Lb.$ $plantarum$ AF1 was considered higher than 5.0 g/kg. In the intraperitoneal acute toxicity test, mice were injected intraperitoneally with dosages of 0.7, 0.9, 1.1, 1.3, 1.5, 1.7, 1.9, 2.1, 2.3 and 2.5 g/kg. The intraperitoneal 50% lethal dose ($LD_{50}$) of the $Lb.$ $plantarum$ AF1 was >2.5 g/kg in the male and female mice. No significant changes in the general conditions, body weights, clinical signs, and gross lesions were observed in both sexes of mice to which $Lb.$ $plantarum$ AF1 was administered intraperitoneally or orally. The results suggest that the no-adverse-effect level of $Lb.$ $plantarum$ AF1 is estimated to be more than 5.0 g/kg in the oral route and 2.5 g/kg in the intraperitoneal route.

Atractylodes macrocepala KOIDZ. (AmK) is a herbal medicine and resources of functional food which has been used for the treatment of indigestion, anorexia, diarrhea and digestive dysfunction. Recently AmK is frequently used as resources of functional food and whitening cosmetics. In this study was carried out to evaluate the acute oral toxicity of Amk in Sprague-Dawley(SD) rats. male and female rats were administered orally with Amk extract of 1,000 mg/kg (low dosage group), 2,000 mg/kg (middle dosage group) and 4,000 mg/kg (high dosage group). We daily observed number of deaths, clinical signs and gross findings for 7 days. No dead SD rats and no clinical signs were found during the experiment period. Also other specific changes were not found between control and treated groups in hematology and serum biochemistry. But we found out feeble histopathological changes in liver fat tissues. In addition no significant changes of gross bady and individual organs weight. These results suggest that water soluble extract of AmK has not acute oral toxicity and oral $LD_{50}$ value was over 4,000 mg/kg in SD rats.
