Vitiligo does not have a baneful influence on life and function of the body directly, but is a serious disease in that most patients suffer from difficulties in social life and considerable stress. We cured a vitiligo patient with a few depigmented patches in front of the left ear using aqua-acupuncture with hominis placenta and psoraleae fructus extract. Since this is just one case report, more case studies and research will be necessary.

It was claimed that the herbal medicine with the function of strengthening the body resistance exerts to enhance the immunity. And the medicine with the effect of eliminating the pathogenic factor is stated to inhibit the immune response. To evaluate the the effects of the herbal medicine on the immune response, the mice were administrated with the herbal medicine for 2 weeks. And the responses were analyzed. As the result, water extract of Radix Astragali, Fructus Psoraleae, Cortex Acanthopanacis, Semen Coicis, Herba Ecliptae, Spica Prunellae, and Radix Sophorae increased the ROI production, while Radix Tripterygia inhibited it. Phagocytic activity was increased after administration of Radix Astragal, Fructus Psoraleae, Cortex Acanthopanacis, Herba Ecliptae, Spica Prunellae and Radix Sophorae. NK cell activity was also significantly inhibited by Radix Tripterygia. Administration of Radix Astragali, Fructus Psoraleae, Cortex Acanthopanacis, Herba Ecliptae, Spica Prunellae and Semen Coicis enhanced the antibodies(hemagglutinin and hemolysin) formation and the appearance of rosette forming cells of the spleen, while Radix Sophorae and Radix Tripterygia decreased it. Radix Sophorae and Radix Tripterygia also decreased the allogenic immune response and mixed-lymphocyte reaction. And all the experimental herbs decreased contact hypersensitivity against dinitroflurobenzene. These results show Radix Astragali, Fructus Psoraleae, Spica Prunellae, Cortex Acanthopanacis, Semen Coicis and Herba Ecliptae enhanced innate immunity, humoral and cellular immune responses. However Radix Sophorae and Radix Tripterygia exert imunosuppressive action. Also these results indicate that the medicine with the action of the strengthening the body resistance enhances the immunity.

The effects of herbal medicine on travecular bone area were studied using ovariectomized rat as an animal model of Type I osteoporosis and SAM P6 as that of Type II. We counted red blood cells(RBC), hemoglobin(Hb), and hematocrit(Hct) using Couter`sR method. Each traditional boiling water extract of Achyrathis Radix, Psoraleae Fructus, Rehmanniae Radix Preparat, and Cornii Fructus and a systemic water extract of Astragali Ractiex was given 5g/kg/day, p.o., for 30 days in a group of 4-5 ovariectormized rats. One ml of blood was taken by tail vein at day 0, 7, 14, 21, and 30 days after administration of the extract. The traditional hot water extract of Cervi parvumn Corni (Cervi) was given the same dose as described above for 14 days in a group of 10 SAM P6 mice and systemic water extract of Astragali Radix was administered as the same dose as above for 30 days in 10 SAM P6 mice. Travecular bone area was measured 5 mcm decalcified and stained thin bone slice by image analysis using a digitalizer. In Type I, ovariectomized rats, administration of Astragali Radix, Rhemanniae Radix Preparat, and Corni Fructus decreased in RBC, Hb and Hct. In Type II, administration of Cervi increased in RBC and Hct and that of Astragali Radix was also elevated RBC. In Type I, any administration of herbal medicine used in this study did not elevate travecular bone area significantly except Corni Fructus showed a trend of increase in travecular bone area. However, Type II, Cervi and Astragali Radix increased in both mean and total travecular bone area. Thus, there are significant difference in response of herbal medicine in different types of osteoporosis.

The effect of herbal medicine on osteoporosis was studied using ovariectomized rats as an animal model of Type I osteoporosis and SAM P6 mice as that of Type II. Each traditiona l boiling water extract of Achyranthis Radix, Psoraleae Radix, Rehmanniae Radix Preparat, Corni Fructus and Mycelia of Ganoderma, and systemic water fraction of Astragali Radix was given 5g(dried herbal weight)/kg/day p.o. for 30 days in each group of ovariectomized rats, SAM R1 and SAM P6. The extract of Cervi parvum Cornu was given for 14 days only. One ml of blood was taken by tail vein at day 0, 7, 14, 21 and 30 days after administration of the extract. Plasma levels of alkaline phosphatase, calcium, creatinine,inorganic phosphate, blood urea nitrogen, cortisol, total $T_3\;and\;total\;T_4$ were measured. In ovariectomized rats, administration of Achyranthis Radix or Corni Fructus decreased in alkaline phosphatase and that of Achyranthis Radix or Psoraleae Radix decreased in calcium comparing to the control (p<0.05). The administration of Psoralese Radix decreased in calcium and increased in urea comparing to day o(P<0.05)(Table I). There were not much changes in plasma calcium, inorganic phosphate, and alkaline phosphatase concentrations after uptake of these herbal medicine used in SAM P6(Table III). However, administration of Astragali Radix altered plasma inorganic phosphate and creatinine levels in SAM R1(p<0.01)(Table UU). The administration of Corni Fructus or Psoralease Radix induced the changes in plasma concentrations of cortisol, total $T_3$ and total $T_4$ in Type I(p<0.05) (Table IV). The uptake of Cervi parvum Cornu increased in total $T_3$ concentration and that of Mycelia of Ganodtragali Radix in SAM P6. However, the uptake of Mycelia of Ganoderma induced changes in cortisol and $T_4$ concentrations in SAM R1(p<0.05). Thus, there were significant differences in responses of herbal medicine in different types of osteoporosis.

Objectives : This study was performed to investigate the single oral toxicity of HBX-6 in Sprague-Dawley (SD) rats. Methods : Twenty SD rats were randomly assigned to four groups of 5 rats each and were administrated singly to female and male SD rats, as an oral dose of 2000 mg/kg. HBX-6 is a newly combined Korean herbal medicine formula 30 % Ethanol extract derived from The Dongui Bogam. Now we are developing the prescription for the aim of improving benign prostatic hyperplasia (BPH) without undesirable side effects. HBX-6 is composed of nine medicinal herbs: Aconiti Lateralis Radix Preparata, Corni Fructus, Cistanchis Herba, Psoraleae Semen, Dendrobii Herba, Morindae Radix, Cuscutae Semen, Trigonellae Semen, Foeniculi Fructus. Animals were monitored for the mortality and changes in the body weight, clinical signs, gross observation and necropsy findings for the 14 days according to "Standard for Toxicity Study of Pharmaceuticals" of Korea Food and Drug Administration (KFDA) guideline and "Acute Oral Toxicity - Fixed Dose Procedure" of OECD Test Guideline. Results : We could not find any mortality. Compared with the control group, significant weight change was not observed in the experimental group. After administration, the more common symptoms were not observed. There were no gross abnormalities in all cases. Conclusions : Taken together, these results suggest that the approximate lethal dose of HBX-6 in both female and male SD rats were considered as over 2000 mg/kg.
