To investigate the effect of Artemisia apiacea Hance on the hair growth of black mouse (C57BL/6), this study was carried out. We obtained chloroform fraction, ethyl acetate fraction, butanol fraction from ethanol extract. When these fractions were administered to the black mouse by the method of skin paste, chloroform extract increased remarkably the hair growth of black mouse. thus Chloroform fraction was devided into 5 fractions from 20:1 to 1:1 with chloroform : methanol. the detail fractions of chloroform fraction were administered to the black mouse. We obtained the result that fraction I, II, III, IV are superior to minoxidil of positive control. Most of all fraction II have an dramatical effect on hair growth of black mouse.

We investigated the cytogenetic characteristics of male black-striped field mouse (Apodemus agrarium) in Korea. Chromosome slides were obtained from blood cell cultures which were synchronized with thymidine blocking or not. In the chromosome slide which synchronization with thymidine blocking was employed on, the GTG(G bands by trypsin using Giemsa)-bands of high resolution were observed. The male black-striped field mouse has 48 chromosomes composed 46 autosomes and XY sex chromosomes. The centromeric regions of autosomes were positive to GTG-banding. According to this investigation, thymidine blocking in cell culture process was useful to get lengthened chromosomes. It may be necessary to employ RBG-banding technique to investigate complementary band patterns between R- and G-banding in black-striped field mouse.

Black mouse에 하나로 원자로의 BNCT시설을 이용하여 중성자(flux:1.036739E+09)를 머리를 정면으로 16 및 32 Gy 조사한 후 생물학적 효과를 관찰하는 일환으로 고환에 대한 물리학적 변화 및 조직 변화를 관찰하였다. 조사 후 90일이 경과한 후에 고환의 무게는 변화가 없었으나 고환의 부피는 약간 감소하였으며, 정자수도 감소하였다. 고환의 조직검사에서는 32 Gy 중성자 조사군에서 위축된 정세관의 수가 증가되었으며 stage VI에서의 정세관에서는 정조세포 및 비사기 정모세포가 고갈되어 있음을 알 수 있었다. 중성자 조사(32 Gy)후 고환의 손상이 장기간 경과 후에도 회복되지 않음을 알 수 있었다.

The hair-growth effect of Illite was suggested by some people who were using Illite as a beautifying material. We investigated the hair-growth effect of Illite powder. The hair-growth effects were investigated by two methods; the activity of hair-growth after shaving the hairs on the black mouse (C57BL/6) and the recovery activity of hair-growth after hair-loss induced by cyclophosphamide treatment. Suspension of Illite powder was applied to the back of the black mouse by method of skin paste. Illite promoted significantly the hair growth of mouse in both conditions of shaving and hair-loss. And then we investigated the toxicity which may be induced by Illite when it was administrated orally as a single dose. We could not fond out any significant toxicity induced by single dose oral administration of Illite.

We have synthesized acetylsalicylic acid derivative of eugenol. And also, physico-chemical properties and analysis on this compound were examined. The correlation coefficient of the calibration curve in methanol solution was 0.9998. The hair growth stimulation of eugenol derivative on the hair of black mouse (C57BL/6), was also carried out using Implant method. When its ethanol solution was administered to the black mouse by route of skin, eugenol derivative promoted the growth of hair.

To investigate the antialopecic effect of N-4-salicylomide-2-amino-6-piperidinopyrimidine 3-oxide(SALMI) and its salt on the hair of black mouse (C57BL/6), this study was carrie d out. When salmi and its salt in ethanol solution were administered to the black mouse (C57BL/6) by route of skin, both of them promoted the growth of hair.

The derivative of chrysin 7-O-cyclopropanecarboxylate was synthesized by condensing cyclopropanecarboxylic acid with chrysin in organic solvent, and its structure was identified by NMR, MS, UV IR etc. We also investigated the physico-chemical properties, anti-diabetic effect and set up the quantitative analytical method of this compound. The correlation coefficient of calibration curve on this compound was approximately 0.9985 by absorption spectrophotometry. And, this study was carried out to investigate the hair-growth effect of chrysin derivative to the black mouse (C57BL/6). When this derivative in ethanol solution was administered to the back of mouse by method of skin paste, this derivative promoted the hair growth of mouse.

We have synthesized 4-isonitroso-4H-1-benzopyran and 4-amino-2,3-dihydro -4H-1-benzopyran of chromone derivatives by using condensation method. Physico-chemical properties of these compounds were measured and analyzed by UV and HPLC method. The correlation coefficient of their methanol solutions by UV were 0.9992 and 0.9994, respectively. And oxime compound was resolved within 4 min and had a detection limit of 3 ng at S/N=3 by HPLC using a reversed phase column with three solvents(MeOH, $H_2O$, HAc). The amino compound was resolved within 4.5 min and had a detection limit of 10 ng at S/N=3 by HPLC under the same conditions. Anti-diabetic effect of chromone derivatives were investigated in the streptozotocin (STZ)-induced diabetic rats. Diabetes was induced in male Sprague-Dawley rats by injections of STZ (45 mg/kg, i.v). The investigation of the hair growth effect of isonitrosobenzopyran and 4-aminobenzopyran on the hair of black mouse (C57BL/6) was also carried out. The administraion of their ethanol solution to the black mouse (C57BU/6) through skin them promoted the growth of hair.

We observed the suppressive effect of a powder formulation of African black tea extract prepared from the leaves of Camellia sinensis on type 2 non-insulin dependent diabetic mice, $KK-A^y/TaJcl$. Black tea extract significantly showed suppressive effect of the elevation of blood glucose on oral glucose tolerance test of 8 week-old $KK-A^y/TaJcl$ mice (p<0.05). Long-term treatment with black tea extract showed significant suppression of post-prandial blood glucose and obesity (p<0.05). The weight of the intestine of mice treated with black tea extract was significantly reduced (p<0.05). From these results, African black tea used in this study showed a suppressive effect on the elevation of blood glucose during food intake and the body weight.

Vinegar has been widely produced for a variety of industrial and domestic use as well as medicinal use. For sale of the commercial vinegar with herbal extracts, we produced an experimental black vinegar through sequential fermentation of alcohol, followed by acetic acid according to the manufacturer's procedure. To investigate the effect of anti-obesity of black vinegar on biochemical values, we evaluated enzyme activities via acetyl-CoA carboxylase (ACC), which plays a critical role in the lipid metabolism. We found that increased phosphorylated adenosine monophosphate (AMP) activated protein kinase (AMPK) and ACC in L6 mouse muscle cells treated with the manufactured vinegar. Based on the results, supplementation of experimental herbal black vinegar inactivates ACC, enhancing the phosphorylation of AMPK. Thus, the lipid oxidation and inhibitory effect of fatty acid synthesis by the black vinegar expects to facilitate the anti-obesity activity.
