  • Objective : The purpose of this study is to investigate the effect of Radix Scutellariae on repeated nicotine-induced locomotor activity and c-Fos expression utilizing Fos-like immuno-histochemistry method in the nucleus accumbens, and the striatum, one of the major projection areas of the control DA system. Methods : Male Sprague-Dawley rats were divided into untreated(normal), nicotine-treated (control), Radix Scutellariae-treated(sample) groups, RS group received Radix Scutellariae(100mg/kg, i.p.) 30minutes before injection of nicotine(0.4mg/kg, s.c.) for 7days. Rat were followed withdrawal for 3 days and one challenge for 1day. Results : Systemic challenge with nicotine produced a much larger locomotor activity and expression of c-Fos in the nucleus accumbens and the striatum. Pretreatment with Radix Scutellariae decreased in nicotine-induced locomotor activity and c-Fos expression in the core, shell, straitum area. Conclusion : These results demonstrated that reduction in locomotor activity by Radix Scutellariae may be mediated by reduction of dopamine release and of postsynaptic neuronal activity in striatum, the nucleus accumbens. Out results show neurochemical evidence for the biological effects of Radix Scutellariae that ultimately may help us to understand how Radix Scutellariae can be used to treat nicotine addiction.

  • Obesity is caused by unbalance of energy intake and expenditure, which results in extra accumulation of adipose tissue. Obesity is directly related to metabolic diseases such as diabetes, hyperlipidemia, fatty liver and so on. To investigate the anti-obesity effects of Scutellariae Radix, 70% EtOH extract and water extract of it were tested by in vitro and in vivo studies of fat accumulation. 3T3-L1 preadipocyte cell line was used in a in vitro study of fat accumulation. After 3T3-L1 cells were induced to differentiate into adipocytes, S. radix extract were added and fat accumulation was measured by oil red O staining. In vivo study showed that weight and epididymal/ retro-peritoneal adipose tissues were significantly reduced in mice fed Scutellariae Radix extract compared with control group. Especially, mice fed Scutellariae Radix extract showed reduced serum triglyceride and glucose levels. When adipose tissues were analyzed by microscope, mean adipocyte size was significantly reduced in Scutellariae Radix extract-fed mice. Therefore, this study showed inhibitory effects of Scutellariae Radix on in vitro and in vivo fat accumulation.

  • The antibacterial effects of water extracts of Scutellariate Radix (a dried root of Scutellaria baicalensis GEORGI) and its major flavonoid components, Baicalin and Baicalein, on Salmonella typhimurium, a representative enteric pathogen, were studied. Through a Kriby-Bauer disc analysis, the growth-inhibition activity of Scutellariae Radix against. S. typhimurium was found to be compatible with commercial antibiotics, such as ampicillin, chloramphenicol, and streptomycin. In contrast, the growth of a nonpathogenic E. coli strain was unaffercted by Scutellariae Radix. To examine the effect of polyphosphate kinase (ppk), a putative virulence factor, on the antibacterial activity of Scutellariae Radix, the growth profile of a ppk mutant of S. typhimurium was investigated in a tryptic soy broth containing different concentrations of water extracts of Scutellariae Radix. The ppk mutant was able to grow in 6 mg/ml of water extracts of Scutellariae Radix, whereas in 6 mg/ml of water extracts of Scutellariae Radix, whereas the wild-type could not, implying that the inactivation of ppk made S. typhimurium more resistant to the antibacterial activity of Scutellariae Radix. No enhanced resistance was observed in a ppk mutant of S. typhimurium complemented with a ppk expression vector. The attenuation of the virulence by ppk inactivation was also observed in a virulence assay using BLAB/c mice. Neither Baicalin nor Baicalein exhibited any growth-inhibition activity against S. typhimurium. The water extracts of Scutellariae Radix stimulated the transcription of ppk, especially in the early growth-stage of S. typhimurium.

  • Flavonoids from Scutellariae Radix possessed a dual function both as an anti-inflammatory agent and an enhancer of cellular activity in gingival fibroblast. The purpose of this study was to evaluate on the toxicity of ethanolic extract from the root of Scutellariae Radix Georgi and its flavonoids, Wogonin, Baicalein, and Baicalin were isolated and purified by the following method. The crude drug was extracted with ethyl acetate and the residue was dissolved in ethyl alcohol. The ethyl alcohol soluble fraction was separated, concentrated, and then chromatographed on a silica gel column. The acute oral LD 50 in rats was determined for EtOH ex. of Scutellariae Radix and three compounds were evaluated with a single oral gavage at three graded dosage levels. The acute intravenous LD 50 was determined with a single intravenous injection via the jugular vein at three graded dosage levels. Groups of 5 male and 5 female rats, 6 week of age at the start of the study, were fed diets containing 3 graded dosage levels for 14 days. Groups of 5 male and 5 female hamster received O.5ml of the test article at once in a day for 5 days to the buccal cheek pouch for two minutes each. The acute oral LD50 for EtOH ex. of Scutellariae Radix is 1430mg/kg, and for Wogonin 1320mg/kg, for Baicalein 1250mg/kg, for Baicalin 1330mg/kg. The acute intravenous toxicity of EtOH ex. of Scutellariae Radix and its extracts was found to be 27mg/kg body weight No toxic effects were observed in rats fed up to 200mg/kg of EtOH ex. of Scutellariae Radix, Wogonin, Baicalein and Baicalin in the diet for 14 days. The acute Mucouse Membrane LD 50 in hamsters was found to be greater than 100mg/kg. These results suggested that EtOH ex. of Scutellariae Radix and its flavonoids are safe for oral care products using limited amount of extract.
