  • To determine whether topical application of trimix extracts of Mylabris phalerata Pall., Arisaematis Rhizoma and Pinelliae Rhizoma Ternata lead to affects on the hair growth activity in C57BL/6N mice. To examine the hair growth activity of the extracts of Mylabris phalerata Pall., Arisaematis Rhizoma and Pinelliae Rhizoma Ternata gross, microscopic, and immunohistochemical method were performed. In order to examine the mRNA expression of hair growth related substance, RT-PCR method was performed. Experimental group I on day 14, The most extensive hair growth activity was observed in whole skin area of all the mice whose hair had been clipped. Brdu immunoreactive cells of all the experimental groups were more heavily stained in epidermis, bulge, outer root sheath, inner root sheath, subcutaneous tissue, hair bulb and cutaneous trunci muscles than that of control group on day 12 of hair growing cycle in C57BL/6N mice. VEGF immunoreactive density of all the experimental groups was more heavily stained in epidermis, bulge and cutaneous trunci muscles than that of control group on day 12. FGF and c-kit immunoreactive cells of all the experimental groups were heavily stained in epidermis, outer root sheath, inner root sheath and cutaneous trunci muscles on day 12. PKC-$\alpha$ immunoreactive density of all the experimental groups was mildly stained in epidermis and cutaneous trunci muscles than that of control group on day 12. On day 12, the expression of bFGF (138%, 119%, 120%), VEGF (146%, 144%, 133%), IGF-1 (165%, 141%, 119%) and PLI (121%, 116%, 123&) in each experimental groups was more increased than that of control group. On day 16, The expression of IGF-1 (126%, 149%, 151%) in all the experimental group was more increased than that of control group (100%). The expression of bFGF (92%, 94%) and VEGF (101%, 97%), PL1 (102%, 109%) in all the experimental group was more decreased than that of experimental group I, II on day 12. But the expression of bFGF (109%) and VEGF (127%), and PL1 (105%) in each experimental group III was more increased than that of control group (100%). These experiments suggest that trimix extracts of Mylabris phalerata pall., Arisaematis Rhizoma and Pinelliae Rhizoma Ternata may stimulate the topical hair growth activity and its experimental group I can be useful for treatment of alopecia areata.

  • The present study was carried out to investigate the potential acute toxicity of CKD-602 by a single intravenous dose in Sprague-Dawley rats. Ten males females were used in each test groups: a vehicle control, 34.7, 4l.7, 50.0, 60.0 and 72.0 mg/kg groups, and were given different single intravenous doses of CKD-602 to the test animals. Mortalities, clinical findings, and body weight changes were monitored for the 14-day period following the administration. At the end of l4-day observation period, all animals were sacrificed and complete gross postmortem examinations were performed. One, 1, 2, 8 and 9 cases of deaths occurred in the male dose groups of 34.7, 41.7, 50.0, 60.0 and 72.0 mg/kg, respectively, and 1, 5 and 9 cases in the female dose groups 50.0, 60.0 and 72.0 mg/kg, respectively. An increase in the incidence of clinical signs such as alopecia, skin pallor skin ulcerations, emaciation and change of fecal material was found in the both sexes of all treatment groups. A decrease or Suppression in the body weight was also observed in a dose-dependent manner. In autopsy, male and/or female rats of the treatment groups showed treatment-related gross findings such as splenomegaly, atrophy of the testis, epididymis, seminal vesicles, ovary, uterus and thymus which were dose-dependent in incidence and severity. Based on these results, it was concluded that a single intravenous injection of CKD-602 to rats caused significant toxicities in gastrointestinal, hematopoietic, and reproductive systems. The $LD_{50}$ value was 53.8 (95% confidence limit: 48.5~60.6) mg/kg for males and 60.l (95% confidence limit: 55.3~65.8) mg/kg for females. The $LD_{10}$ value was 39.9 (95% confidence limit: 3l.7~44.8) mg/kg for males and 50.3 (95% confidence limit: 40.6~54.8) mg/kg for females.

  • 본 연구에서는 인체 두피조직에서 미세수술법을 이용하여 모낭을 성공적으로 분리하였으며 다양한 조건으로 액침기관배양을 수행하였다. 우태아 혈청첨가시 모낭의 길이 성장이 저해되는 것으로 확인되어 무혈청 배지 조성을 시도하였다. 무혈청 배지로는 모낭 기관배양에 널리 이용되는 Williams'E medium을 기본으로 하는 Philpott medium과 자체 개발한 고농도 아미노산과 비타민(B군) 조성의 DHGM(Dongguk hair growth medium)을 이용하였다. 그리고 IMDM은 DHGM의 비교 대조군으로 이용하였다. 연구 결과 Philpott medium과 IMDM으로 배양한 모낭은 구조상으로는 길이 성장이 각각 9일과 12일 정도에 멈추며, 낮은 알카라인 포스파테이즈 발현, CK19 발현이 거의 없는 것으로 보아 세포사멸에 의한 퇴화(regression)가 빠르게 일어나는 것으로 판단되었다. 반면, DHGM으로 배양한 모낭은 상대적으로 긴 기간 동안 성장기의 구조를 보이며 25일까지 지속적인 길이 증가 및 3배 높은 알카라인 포스파테이즈 발현, 전반적인 CK19 발현을 나타내었다. 따라서 고농도의 아미노산 및 비타민 배지 조성이 생체 외에서 모낭을 장기간 배양하는데 중요한 역할을 하는 것으로 판단된다. 이러한 배양 방법은 장기간 검사를 필요로 하는 모낭에 대한 기초 생물학적 연구뿐만 아니라 새로운 탈모치료제의 효능 평가 분야에 이용될 수 있을 것이다.

  • This study evaluated the efficacy of topical eprinomectin (0.5% pour-on solution, $Eprinex^{(R)}$, Merial) against Chorioptes texanus (C texanus) infestation in dairy cows reared in Korea. Dairy cows naturally infected with C texanus showed skin lesions as alopecia, erythema, excoriations and crusts on the tail head, the caudal folds, the back of udder and the rump area. Fourteen adult Holstein dairy cows with chorioptic mange at National Institute of Animal Science were selected on the basis of gross lesion and microscopic examination. Experimental dairy cows infected with chorioptic mange were treated with eprinomectin ($Eprinex^{(R)}$, Merial, France) at the rate of 1 ml /10 kg/BW. Evaluation of therapeutic effect is based on mite counts and gross lesion at weekly interval for 6 weeks. Milk yields were measured every day and calculate at the mean of milk yield at weekly interval. Mange mites absolutely removed after 1 week of topical eprinomectin against C. texanus infestation on dairy cows. The skin lesion of dairy cows infested with C. texanus recovered normal status after 6 weeks of eprinomectin treatment. After eprinomectin treatment, return to the normal level of milk yields in diary cows infested with C. texanus has indirectly indicated that C. texanus infestation have negative effect on productivity of dairy farm. However, it would be suggested that the investigation of actual condition and the effective control method of C. texanus infestation of dairy farms in Korea should be studied in the future.

  • The hair cycle (anagen, catagen, and telogen) is regulated by the interaction between mesenchymal cells and epithelial cells in the hair follicles. The proliferation of dermal papilla cells (DPCs), mesenchymal-derived fibroblasts, has emerged as a target for the regulation of the hair cycle. Here, we show that vanillic acid, a phenolic acid from wheat bran, promotes the proliferation of DPCs via a PI3K/Akt/Wnt/β-catenin dependent mechanism. Vanillic acid promoted the proliferation of DPCs, accompanied by increased levels of cell-cycle proteins cyclin D1, CDK6, and Cdc2 p34. Vanillic acid also increased the levels of phospho(ser473)-Akt, phospho(ser780)-pRB, and phospho(thr37/46)-4EBP1 in a time-dependent manner. Wortmannin, an inhibitor of the PI3K/Akt pathway, attenuated the vanillic acid-mediated proliferation of DPCs. Vanillic acid-induced progression of the cell-cycle was also suppressed by wortmannin. Moreover, vanillic acid increased the levels of Wnt/β-catenin proteins, such as phospho(ser9)-glycogen synthase kinase-3β, phospho(ser552)-β-catenin, and phospho(ser675)-β-catenin. We found that vanillic acid increased the levels of cyclin D1 and Cox-2, which are target genes of β-catenin, and these changes were inhibited by wortmannin. To investigate whether vanillic acid affects the downregulation of β-catenin by dihydrotestosterone (DHT), implicated in the development of androgenetic alopecia, DPCs were stimulated with DHT in the presence and absence of vanillic acid for 24 h. Western blotting and confocal microscopy analyses showed that the decreased level of β-catenin after the incubation with DHT was reversed by vanillic acid. These results suggest that vanillic acid could stimulate anagen and alleviate hair loss by activating the PI3K/Akt and Wnt/β-catenin pathways in DPCs.

  • A clinical study of 106 cases of $Henoch-Sch{\ddot{o}}nlein$ purpura was made. The author analyzed the result of Korean traditional medical therapy. It was observed more frequently in female at the sex ratio of 1:1.3. The most prevalent age group was $4{\sim}9$ years(56.6%). In seasonal incidence, the cases were frequent during spring(50%), and the main specific history was upper respiratory tract infection(48.1%). The duration of contraction was $420.9{\pm}1079.3$ days. The adults were more chronic than children (p<0.05), The clinical manifestation showed in the skin (100%), the gastrointestinal tract(62.3%), the joints(64.2%), the kidney(25.3%), genitourinary system(11.3%), headache(6.6%), and scalp edema(4.7%) respectively. The first outbreak of symptoms was showing of skin purpura in 77 cases(72.6%) the highest frequency. and the gastrointestinal tract and joints were 16(15.1%) and 12 cases(11.3%) respectively. Of all patients, 22 cases(20.8%) experienced recurrences and 47 patients(44.3%) experienced hospitalization treatment. In the patients group which were recurrence experiences, the recurrence rate was high with patients(63.2%) who usually enjoyed meats and convenience foods and in patients(84%) who treated URI with chemical drugs(p<0.05). The patients group(68.9%) that took steroids also experienced a relatively high recurrence rate. Out of the patients(68.9%) who took treatment with steroids, 46.6% experienced side effects, in orders moon face(100%), weight gain(47.1%), appetite increase(52.9%), and acne. alopecia(11.8%), etc. There was a statistically significant relationship between the period of taking the steroid and the side effects(p<0.05), As the result of the herbal medicine treatment(treatment period: $6.7{\pm}6.2$ weeks, a follow-up survey during $15{\sim}24$ months), 67 patients(91.8%) among the 73 patients(68.9%) under 18 years old recovered completely but 3 cases(4.5%) recurred. 23 patients(69.7%) among the 33 patients(31.3%) above 19 years recovered completely but 5 cases(21.7%) recurred.

  • Mylabris is the dried body of the chinese blister beetle. The species used in medicine are Mylabris phalerata and M. cichorii. In recent studies, it has been found that Mylabris possesses antitumor properties, increases the number of leukocytes, and has irritant effects on the urinary organs. The crude extracts of Mylabris have been noted for their highly irritant action and other traditional uses of Mylabris include treatment of poor local blood circulation. The active constituent of Mylabris is cantharidin. The chemical is notable for its vesicant properties, but with severe side effects such as nephrotoxicity. This experiment examined the effect of extracts and fractions, obtained from Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. First, we examined the effect of an extracts, obtained from the alcohol extracts of dried Mylabris phalerata Pall. on hair growth activity of the C57BL/6N mice after topical application to skin. Second, we examined on hair growth activity of the cantharidin fraction of Mylabris phalerata Pall. compared to the control and 1% minoxidil groups. Third, we investigated the number of hair follicle and mast cells after topical application of extracts of Mylabris phalerata Pall. to skin for 16 days. The results were as follows: Hair growth effect from the extracts of Mylabris phalerata Pall.(0.312%) was observed in 80% of mice whose hair had been removed in 13 days. Hair growth effect from the extract of Mylabris phalerata Pall.(0.312 and 0.625%) and 1% minoxidil group was observed in 100% of mice whose hair had been clipped in 20 days. Hair growth effect from the cantharidin fraction(0.5%) and water fraction(0.5%) of Mylabris phalerata Pall. was observed in 100% of mice whose hair had been clipped in 24 days. The hair growth effect on the cantharidin fraction(0.125%) was observed to be strong compared with the minoxidil(3%) group, commercial hair growth agents, in mice whose hair had been clipped in 19 days. In the spontaneous alopecia mice model, the hair growth effect from the cantharidin fraction (0.125%) was observed to be strong as compared with the states before the 13 days experiment. These experiments suggest that extracts and fractions of Mylabris phalerata Pall. may stimulate the topical hair growth activity in low doses.
