In clinical use, irinotecan hydrochloride (CPT-11; 7-ethyl-10-[4-(piperidino)-1-piperidino]carbonyloxycamptothecin), a novel antitumor agent, causes a relatively high incidence of severe forms of diarrhea. We investigated whether baicalin, an inhibitor of beta-glucuronidase, which deconjugates the glucuronide of the active metabolite of CPT-11, SN-38(More)
Fetal female urogenital anomalies are often difficult to evaluate by ultrasonography, especially in late gestation. We report a case of fetal hydrometrocolpos detected at 35 weeks of gestation. Ultrasonography revealed a large retrovesical septate hypoechogenic mass in the fetal abdomen, however the sonographic findings were inconclusive. Magnetic resonance(More)
Dispase is a bacterial neutral protease which is obtained from the culture filtrate of Bacillus polymyxa. After 24-h treatment of the human skin with 500 and 1000 U/ml dispase, the epidermal sheet was easily peeled from the dermis, and its undersurface retained rete ridges. Electron microscopic observation showed that the basal surface was composed of cells(More)
Active forms of vitamin D3, 1 alpha-hydroxyvitamin D3 and 1 alpha,25-dihydroxyvitamin D3, were administered in an open-design study to 40 patients with psoriasis vulgaris in three ways: to 17 patients 1 alpha-hydroxyvitamin D3 was given orally at a dose of 1.0 micrograms/day for 6 months, to four patients 1 alpha,25-dihydroxyvitamin D3 was given orally at a(More)
The effects of all-trans retinoic acid (RA) on melanogenesis and the mechanism of its action in topical treatment have not been elucidated. The purpose of this study was to determine the effects of RA on melanogenesis in the pigmented skin equivalent as well as in monolayer culture of melanocytes, and to determine whether RA, hydroquinone (HQ), and(More)
The expression of proliferating cell nuclear antigen (PCNA), also called cyclin, in human keratinocytes was examined by using the serum obtained from a SLE patient and a murine monoclonal antibody against PCNA/cyclin. In the normal epidermis, few of the nuclei were labeled with anti-PCNA/cyclin. This was in contrast to the positive nuclear staining seen in(More)
Methods for the optimized culturing the hair cells from 4-day-old C3H mice are described. The skin was obtained and soaked in 500 unit/ml dispase at 4 degrees C for 24 hr. Then the epidermis was removed and the dermis was further treated with 0.25% collagenase for 1 hr at 37 degrees C. The hair roots isolated by collagenase digestion of the dermis were(More)
The effects of conventional mechanical ventilation (CMV) and high-frequency oscillatory ventilation (HFO) on intraalveolar expression of the tumor necrosis factor-alpha (TNF-alpha) gene were studied in surfactant-depleted rabbits. After lung lavage with saline, 13 rabbits were administered either CMV (n = 6) or HFO (n = 7) for 1 h at an FiO2 of 1.0 and a(More)
We investigated the depression induced by human interferons using the forced swimming test in mice. Intravenous (i.v.) administration of interferon-alpha s (natural interferon-alpha, recombinant interferon-alpha-2a and recombinant interferon-alpha-2b, 600-60000 IU/kg) increased the immobility time in the forced swimming test in a dose-dependent manner, but(More)
