To evaluate the modifying effect of Kwao Kreu, Pueraria mirifica (PM) well-known as a rejuvenating folk medicine from Thailand, peri- and post-natal studies were carried out in rats. PM extract was administered to pregnant Sprague Dawley (SD) rats by oral gavage from gestation 6 (GD 6) to postnatal day 21 (PND 21). The amount of administered in this study was 0.042, 0.42 and 4.2 mg/kg/day, respectively. There were no treatment related changes of dams in deaths, clinical signs, and parturition. Treatment related changes in body weight, food consumption and lactation of dams were not observed. F1 fetuses in external abnormality, physical development, reflex/sensory functions and behavioral development were not found. No adults and F1 fetuses in organ weight was found with the exception of vagina and uterus of F1 fetuses. The results showed that PM extract, up to 4.2 mg, had no adverse effects on the peri- and post-natal development of rats. Therefore, PM extract has no adverse effects on peri- and post-natal development of rats.

Because cleaning products are part of our everyday lives, it is essential that they should not present significant risks to health. However, many petrochemicals in most soaps and detergents can be absorbed through the scalp and skin and, over time, accumulate in the organs and tissues. This accumulation may result in brain, nerve, and liver damage. Therefore, it is interested in developing non-harmful detergent. According to Korea Research Institute of Chemical Technology, GC-100X may be non-harmful and non-corrosive alkaline ionic water (pH 12). It is composed of hydroxyl radicals and supplemented with xylitol. To evaluate influence of GC-100X on rats and beagles, GC-100X was diluted with distilled water (25%, 50%, and 100% solution respectively). Each of diluted GC-100X was daily treated per oral. In body weight analysis, urinary analysis, ophthalmological test and autopsy, we did not find any significance, but in serum biochemical analysis and hematological analysis, we found some significances in middle dose group compared with control group. These significances in serum biochemical analysis and hematological analysis may be not induced by GC-100X, because it was not found to be significant from control group in histopathological examination. Thus, it is concluded that NOEL(No Observed Effect Level) of GC-100X may be higher than all treatment doses used in this study, and GC-100X may be a non-toxic detergent.

Two local irritation and skin sensitization studies of nonspecific immunostimulator, BARODON® were carried out with New Zealand White rabbits and Hartley guinea pigs. In skin irritation test of male New Zealand White rabbits, body weights were not significantly changed and there were no responses after treatment for 24 or 72 hours and the Primary irritation index (P.I.I.) was ''0''. And, in the eye irritation test, there were chemosis in some of rabbits. One of 3 rabbits in washing group was detected chemosis after 24 and 72 h following treatment and 2 of 6 rabbits in non-washing group were detected chemosis after 24h and 7 days following treatment. Therfore, total score is ''4'' after 24 h and ''2'' after 72 h following treatment by conforming article "some blood vessel are clearly hyperemic". However evaluation value is non-irritant because M.O.I. (Mean ocular irritation index) score is below during the all experimental period and no significance through individuals and exposure time. In skin sensitization, the score of skin reaction was graded I with 0% sensitization rate. Taken together, these results indicate that BARODON® may be non-irritant material.

To evaluate influence of Saposhnikovia divaricata ( Turcz.) Schischk extract on rat, Saposhnikovia divaricata ( Turcz.) Schischk extract was diluted with 0.9% saline (100 mg/ml/kg, 10 mg/ml/kg, and 1 mg/ml/kg, respectively), and each of diluted test material extract was daily treated subcutaneously for 4 weeks and single-treated subcutaneously for 2 weeks. There were no significances in body weight analysis, urinary analysis, and ophthalmological test. However, in serum biochemical analysis and hematological analysis, we found some significances in high and middle dose group compared with control group. These significances in serum biochemical analysis and hematological analysis may be not induced by test material, because it was not found to be significant from control group in histopathological examination. Therefore, it was concluded that NOEL (No Observed Effect Level) of test material extract may be higher than all treatment doses used in this study, and Saposhnikovia divaricata ( Turcz.) Schischk extract may be a non-toxic material

The antigenicity of nonspecific immunostimulator BARODON$^{(R)}$, a newly developed drug, was investigated by tests for passive cutaneous anaphylaxis (PCA) and active systemic anaphylaxis (ASA) in mice and guinea pigs. In ASA test using guinea pigs, there were no significant clinical symptoms in all individuals of low(0.3%) and high(3%) dose of both groups treated with only BARODON$^{(R)}$ and cotreated with BARODON$^{(R)}$ and adjuvant group. In PCA test, blue spots of Evan's were observed from $2^6$ to $2^{10}$ in homologous group and from $2^2{\sim}2^5$ dilution rate in heterologous group of BSA treated positive control group. However, intradermal sensitization with antiserum obtained from low (0.3%) and high (3%) dose of BARODON$^{(R)}$ only treatment group and treated-with-adjuvant group, followed by intravenous injection of respective antigen and Evan's blue mixture (1:1) showed no blue spot observed. In conclusion, BARODON$^{(R)}$, as showed in ASA and PCA test, did not cause anaphylatic shock when treated 3 and 10 times higher than clinically intended dose, nor induce IgE, so that might not have antigenic properties in mice and guinea pigs.

This study was performed to evaluate single and repeated-dose toxicities of Bee Venom Extracts (F1, F3) in Spraque-Dawley. F1 was injected subcutaneously to rat at dose levels of 0, 0.0002, 0.002, 0.02 mg/kg/day for single-dose toxicity study and repeated-dose toxicity study. F3 was injected subcutaneously to rat at dose level of 0, 0.003, 0.03, 0.3 mg/kg/day for single-dose toxicity study and repeated-dose toxicity study. In both studies, there were no dose related changes in mortality, clinical sign, body weight change, food and water consumption, opthalmoscopy, organ weights, urine analysis, biochemical examination, and hematological findings of all animals treated with Bee Venom (F1, F3). Gross and histopathological findings revealed no evidence of specific toxicity related to Bee Venom (F1, F3). These results suggest that the subcutaneous NOEL (No Observed Effect Level) of Bee Venom (F1, F3) may be over F1 - 0.02 mg/kg, F3 - 0.3 mg/kg.

[ $BARODON^{(R)}$ ] is a multi-purpose, high functional alkali solution made by mixing and liquid-ionizing silicon, calcium, sodium, borax, organic carbon chemicals and silver. In this study, we have investigated the apoptotic potential and mechanistic insights of $BARODON^{(R)}$ in human gastric cancer cell line (AGS cells). In MTT assay, $BARODON^{(R)}$ reduced cell viability in AGS cells. Morphological features of apoptosis with marked cytoplasmic vacuolation and appearance of apoptotic peaks in flow cytometry were observed in AGS cells with$BARODON^{(R)}$ treatment. In addition, $BARODON^{(R)}$ induced apoptosis of stomach cancer cell is related to bax up-regulation, caspase 7 protease activation and subsequent cleavage of poly (ADP-ribose) polymerase (PARP). These results suggest that BARODON can induce the apoptosis of AGS cells through modulation of bcl-2 family and the activation of intrinsic caspase cascades, indicating that it is potentially useful as a anti-cancer agent.
