A 31-year-old male patient had malignant atrophic papulosis that afected the skin only. He had multiple typical porcelain-white skin lesion on the face and trunk without abdominal symptoms. Histopathologic studies showed moderate inflammatory infiltration in addition to the typical cone-shaped region of necrobiosis, There are no satisfactory treatment modes, and in the present case, the patient's condition improved transiently on oral medication of aspirin, but we lost the contact with him afterwards.

OBJECTIVE: The purposes of the present study were to investigate the effect of gamma-radiation on the expression of inhibin-alpha proteins and genes for inhibin alpha, betaA, and betain the ovary. METHODS: Immature mice were whole-body gamma-irradiated with 25% of a lethal dose. At time 0, 3, 6, 12, and 24 hours after the irradiation,the ovaries were collected and used for immunohistochemistry for inhibin-alpha, and RT_PCR for inhibin-alpha, betaA, and betaB. RESULTS: The expression of the immunoreactive inhibins-alpha was maintained at 12 hours post-irradiation and reduced thereafter. The expression of inhibin-alpha mRNA was significantly increased with the time after the irradiation. However there were no significant changes in the expression of betaA and betaB mRNAs. CONCLUSION: It might be thought that inhibin acts as one of the regulatory factors in the gamma-radiation-induced follicular atresia in mice

The purpose of this paper was to report a successful treatment of transluminal Nd:YAG laser embolysis (NYE) for branch retinal artery occlusion (BRAO) with visible emboli. Two patients with acute, severe vision loss secondary to a branch retinal artery occlusion with visible emboli in one eye underwent NYE. A complete ocular examination was performed which included biomicroscopy of the posterior pole of the retina, intraocular pressure measurement, fundus color photographs, and fluorescein angiography (FA). After the NYE, the two patients showed dramatic improvements in best-corrected visual acuity, as well as, immediate and dramatic restorations in flow past the obstructed arteriole in FA. NYE is a treatment modality to be considered in patients with BRAO who present acutely with severe vision loss and a visible embolus.

Our purpose is to describe a successful twin pregnancy and delivery after intracytoplasmic sperm injection (ICSI) followed by calcium ionophore with spermatozoa from a globozoospermic man. On the second attempt of ICSI, all of eight metaphase II oocytes were fertilized with treatment with calcium ionophore. Day 3 transfer of six normally developing embryos resulted in an ongoing twin pregnancy, and two preterm healthy babies were born in the 33th week of gestation. To the best of our knowledge, this is the first report of pregnancy and delivery after ICSI followed by calcium ionophore with spermatozoa from a globozoospermic man in Korea.

Recently, a hydroxyapatite sphere has been increasingly used as a buried integrated orbital implant for the great improved motility of the prosthesis after enucleation. To allow more rapid ascess of vasculature into the hydroxyapatite implant, Dacron as a new synthetic wrapping material of the implant for anophthalmic sockets had been used and compared histologically with donor sclera in rabbits. At 4 weeks after implantation, fibrovascular ingrowth was found mainly near the scleral windows, where fibrosis extended 2 mm centrally in scleral-wrapped implants. In Contrast, in Dacron-wrapped implants, there was extensive fibrovascular infiltration through Dacron filaments and windows as well, making the hydroxyapatite sphere completely invested with fibrovascular tissue to the center within 4 weeks of implantation. Thus, Dacron as a new wrapping material appears to allow a more rapid vascularization into the hydroxyapatite implant than other collagen material without any serious complications, resulting in early rehabilitation with an artificial eye.

The purpose of this study is to evaluate the histopathologic findings after experimental penetrating keratoplasty using Dacron-Gore-Tex(R) combined graft in rabbits and the clinical efficacy of the treatment of corneal perforation using synthetic materials. Type A which used end to end fixation showed better results than that of type B which used intralamellar fixation and, however, complications and instability of graft occured in most eyes of both types. Type C which modified type B and reduced the thickness of intralamellar portion of graft showed relatively good results compared with type A and B, but there was still instability. Leakage from anterior chamber in early postoperative period prior to fiibrovascular invasion into graft was considered as the main cause of instability of graft. Therefore we performed type D which emphasized on preventing leakage, and well-maintained anterior chamber without extrusion of graft, that is, the best result among all 4 types was observed until 6 weeks postoperatively. Although further study is needed, we think that Dacron-Gore-Tex(R) combined graft can be a good substitute for the management of corneal perforation.

The purpose of this study was to verify whether small intestinal peristalsis could be observed and quantitatively assessed using pulsed-Doppler ultrasound. Pulsed-Doppler ultrasound was used to evaluate small intestinal peristalsis after a meal in ten normal dogs and ten sedated dogs. The small intestinal peristalses were measured 0, 1, 3, 6, 9, 12, and 24 hours after a 24-hour fast and after feeding. The number of small intestinal peristalsis were 0.133/min, 0.100/min, 0.033/min, 0.167/min, 0.070/min, 0.067/min, and 0.100/min in the fasted dogs, and 1.667/ min, 0.933/min, 1.133/min, 1.234/min, 1.933/min, 1.533/ min, and 0.533/min in fed dogs, respectively. In the dogs sedated with xylazine HCl, the number of small intestinal peristalsis was significantly reduced (p<0.01). However, in the dogs treated with ketamine HCl and acepromazine, the number of small intestinal peristalsis remained unchanged. Therefore, it can be concluded that pulsed-Doppler ultrasound allows graphic visualization of the intestinal movements, which can be subjected to qualitative and quantitative analysis, and may be suitable for a non-invasive study of small intestinal motility.
