Acute and subacute toxicity of Artemisia asistica Nakai Aqua-acupuncture Solution (ANAS) were studied in ICR mice. In acute toxicity test, mice were injected intraperitoneally with single dose of $1{\times}$, $5{\times}$, $10{\times}$ ANAS, and toxicological responeses were observed for consecutive 14 days. Mortality, body weight changes, organ weight, and serum chemistry were performed. The mortality and body weight changes of mice treated with $1{\times}$ and $5{\times}$ ANAS were not affected during the experimental periods. With the $10{\times}$ ANAS treatment, there were dead animals and changes of body weight, organ weight and serum biochemical values were observed during the experimental period. In subacute toxicity test, mice were injected intraperitoneally with doses of $1{\times}$, $10{\times}$ ANAS for 14 days. No difference was found between control and $1{\times}$ ANAS treated group in mortality, changes of body weight and organ weight, and serum biochemical values. However, Dead animals, changes of body weight and organ weight, and increased serum biochemical values were observed with $10{\times}$ ANAS treated groups. These results suggest that $1{\times}$ ANAS causes no toxicity in acute and subacute toxicity tests. However $10{\times}$ ANAS causes toxicity in both tests.

The aim of this study was to investigate the acute and subacute oral toxicity of crude antifungal compounds produced by Lactobacillus plantarum HD1 in Sprague-Dawley rats. In the acute toxicity study, the crude antifungal compounds (0.625, 1.25, 2.5, and 5.0 g/kg) did not produce mortality, significant changes in general behavior, or changes in the gross appearance of the organs. In the subacute toxicity study, the crude antifungal compounds were administered orally to rats at doses of 0, 0.5, 1.0, and 2.0 g/kg daily for 28 days. There were no test article-related deaths, abnormal clinical signs, or body weight changes. The study also showed no significant differences between the control and treated groups in hematological and serum biochemical parameters, histopathological examination, or any other findings. These results suggest that acute or subacute oral administration of crude antifungal compounds from L. plantarum HD1 is not toxic in rats.

In this study, we assessed the acute and subacute toxicity of Angelica gigas Nakai (A. gigas Nakai) extracts, which are comprised of decursin and decursinol angelate (D/DA) in rats. For the oral acute toxicity test, Sprague-Dawley (SD) male and female rats were gavaged with two doses of D/DA (200 and 2,000 mg/kg body weight) and then observed for any toxic symptoms for 2 weeks. The LD$_{50}$ value for the rats was greater than 2,000 mg/kg body weight for both male and female rats, which indicates that there were no toxic symptoms induced by doses of up to 2,000 mg/kg body weight. For the subacute toxicity study, rats were treated with D/DA at doses of 2 and 20 mg/kg body weight once a day for 30 days. There were no significant changes in body weight and food intake observed during the subacute toxicity study. In addition, no differences were observed between the control and treated groups when urinalysis was conducted or when hematology and biochemical parameters were evaluated. Finally, histopathological examination of the organs did not reveal any lesions in the control or treated groups. Taken together, these findings indicate that D/DA is safe and non-toxic.

Acute and subacute oral toxicity of $HELIKIT^{TM}$ ($^{13}C-urea$) were carried out in Sprague-Dawley rats of both sex. The toxicity of $HELIKIT^{TM}$ was compared with urea($^{12}C-urea$ which is used for control). In acute toxicity studies, we daily examined number of deaths, clinical signs, body weights and pathological examination for 14 days after single oral administration of HELIKIT or urea($^{12}C-urea$) at a dose of 5000 mg/kg. The subacute oral toxicity was investigated in Sprague-Dawley rats treated with $HELIKIT^{TM}$ at a dose of 40, 200 and 1,000 mg/kg/day or $^{12}C-urea$ at a dose of 1,000 mg/kg/day for 4 weeks. In acute toxicity studies, $HELIKIT^{TM}$ and urea did not show any toxic effect in rats and oral LD50 value was over 5,000 mg/kg rats. In subacute toxicity studies, no death occured and no drug-related changes were found in clinical observations; body weight, food consumption, opthalmoscopy. auditory test, urinalysis, hematology, blood chemistry, gross pathological examination or organ weight between $HELIKIT^{TM}$, urea and control groups. In histopathological examinations, the slight thickening of mucosa of the limiting ridge in the stomach was noted in the animals treated with $HELIKIT^{TM}$ at a dose of 1,000 mg/kg/day and also the changes in urea group at a dose of 1,000 mg/kg/day was found, but all of these changes in the changes in ures group at a dose of 1,000 mg/kg/days was found, but all of these changes in the stomach regressed after withdrawal of the test article for 2 weeks and reversibility of the effect was revealed. These results indicate that the non toxic dose level of $HELIKIT^{TM}$ was 1,000 mg/kg/day in the 4 weeks-repeated dose study, suggesting that the substitution of $^{13}C$ for carbon in urea molecule has no effect on the toxicity of urea and changes in stomach are reversible.

The acute and subacute toxicity of water soluble dimethyl dimethoxy biphenylate derivative (new DDB), hepatitis therapeutics, were investigated in SD rats. In the acute toxicity study, body weights and clinical signs were observed for 7 days after the intravenous injection of new DDB at doses of 140, 182, 236, 307 and 400 mg/kg(r=1.3). Death. Severe convulsion, tremor and decrease motor activity were observed in almost treated groups (except the 140 mg/kg treated group). Changes of body weight in treated groups were not significantly different from control group. Autopsy of survived animals revealed no abnormal gross findings related to new DDB. As a results, the $LD_{50}$ values of new DDB were 244.1 mg/kg for male and 232.5 mg/kg for female. In subacute toxicity study, body weights and clinical signs were observed after intravenous injection of new DDB at doses of 57, 75 and 100 mg/kg/day for 28 days. Death, decrease motor activity and tremor were observed above 75 mg/kg treated groups. Statistically significant changes were observed in hematological and biochemical parameters of new DDB-treated groups; however, these changes were within normal range and had no relationship with dosage. Several abnormal findings were observed in microscopic examination of tissue; however, these findings were not caused by new DDB but environmental factor. The no toxic dose level of new DDB were estimated to be 57 mg/kg/day in this study.

The acute and subacute toxicity of New Wonbangwoohwangchungsimwon (NSCH) which was used l-muscone as substitutive material of musk were investigated in S.D. rats. In intraperitoneal acute toxicity test, rats were injected intraperitoneally with five dosages of 0, 500, 710, 1,000, 1,410 and 2,000 mg/kg. Body weights were significantly decreased at 500 and 710 mg/kg dose group in male and abnormal autopsy findings were founded in both sexes at all dose. Intraperitoneal $LD_{50}$ of NSCH was 1,088.3 mg/kg in male and 1159.3 mg/kg in female rats. In the subacute toxicity study, NSCH was administrated orally to both sexes of rats for 4 weeks as several doses(0, 320, 800, and 2,000 mg/kg). There were neither dead animals nor significant changes of body weights during the experimental period. In addition, no differences were found between control and treated groups in clinical signs, urinalysis, hematology, serum biochemical analysis, and other findings. Above data strongly suggest that no observed adverse effect level of NSCH might be over 2,000 mg/kg/day in this study.
