The amebicidal activity of traditional anitiamoebic drug (emetine, carbasone, diodoquin, chloroquine, atabrine, chloramphenicol and tertracycline) and newly appeared chemicals(niridazole, metronidazole and No. 8603 substance) were assayed by in vitro experiment using five strains of human originated E, histolytica. The variety of amebicidal activity of drugs by the strains were discussed. Ranges of amoebicidal activity of traditional antiamoebic drugs kept almost similar titers of previous reports at the concentration; 1:5,000 to 1:20,000 with emetine hydrochloride, 1:10.000 to 1:20,000 with carbarsone, 1:8,000 to 1:16,000 with diodoquin, 1:50,000 with chloroquine, 1:1,000 to 1: 4,000 with atabrine ,1:1,000 to 1:2,000 with chloramphencol and 1:5,000 to 1:8,000 with tetracycline. The newly appeared chemicals showed higher amebicidal titres at the concentration; 1:500,000 to 1:5,000,000 with niridazole, 1:50,000 to 1:100,000 with metronidazol and 1:100,000 to 1:500,000 with No.8603 substance. Emetine, chloramphenicol and No. 8603 substance showed amebicidal activities at lower concentration to intestine originated amebae (YS 14, YS 15 and NAMRU II strain) than to liver originated amebae (YS 24 and YS 25 strain ), while carbarsone, chloroquine and metronidazole showed the activity at higher concentrations. Diodoquin showed lower amebicidal titres to trophozoite borne amebae (NAMRU II, YS 24 and YS 25 strain) than to cyst borne amebae(YS 14 and YS 15 strain), but niridazole showed converse results. The concentration of atabrine for amebicidal activity was not constant according to strains of the amoeba, but tetracycline showed almost settled titers.

We describe herein a case of tick bite ocurring to a 23-year-old man who has a characteristic lesion clinically and histopathologically. The tick(Ixodes sp.) was still attached to the brownish and erythematous, indurated skin of the scrotum. The engorged tick which was carefully removed from the skin with a scalpel was 8.7mm in length and 5. 5 mm in width. Histopathologically, characteristic amorphous eosinophilic materigl is deposited around a round space where the hypostorne of the tick was inserted. Heavy inflammatory cell infiltratton in the mid and lower dermis is composed mainly of neutrophils and eosinophils. A certain area of the lower dermis shows edema and capillary dilatation along with the mixed inflammatory cell infiltration, TVide excision of the indurated lesion including the tick was done. The clinical and hsitopathological findings of the tick bite was discussed.

We report a case of congenital vellus hamartoma, which consists of numerous matured vellus hair follicles and sebaceous glands. This patient is 4-month-old male with multiple, variable sized nodules on the right epicanthsl fold area since birth. Histopathologically, some of the infundibular portion of the vellus hair shows irregular and reticulated hyperplasia. There are numerous well-formed vellus hair follicles surrounded with thick fibrous sheath and some of them are associated with rudiment sebaceous glands.

Acrokeratoelastoidosis of Costa is a rare palmoplantar keratoderma with autosomal dominant inheritance. It is clinically charaeterized by small, firm, yellowish, shiny, translucent papules occumng over the dorsal hands, the knuckles, and the lateral margine of the palms and soles. Histologically, the characteristic features are hyperkeratosis, aeanthosis, and most strikingly, fragmentation of coarse elastic fibers within the dermis. The lesions usually begin in early childhood and progress slowly. We herein report two familial cases of acrokeratoelastoidosis of Costa showing typical clinic1 and histopathological features.

We report herein a case of subcutaneous granuloma annulare occured in a 3-year-old girl who had 7 subcutaneous nodules on the scalp, lumbar area, buttock, right tibial area and both ankles. liistopathologically, multiple foci of complete and incomplete collagen degeneration surrounded by histiocytes in a palisading arrangement were seen in the subcutaneous layer. Some vessel walls were thickened and infiltrated with inflammatory cells and many eosinophils were scattered among the inflamrnatory cell infiltrate around the palisaiing granuloma. Five of the lesions disappeared spontaneously and other s decreased in size without specific treatment in 2 months.

Tegafur is a fluoropyrimidine structurally similar to 5-fluorouracil, used in the treatment of advanced gastrointestinal neoplasms. Mucocutaneous side reactions induced by this agent are rare and include photosensitivity of lichenoid and eczematous types, acral erythema, hyperpigmentation and palmoplantar keratoderma. However, to our knowledge, there has been no report of concurrent development of eruptions of two types in a patient. We describe a female patient with breast cancer, presented with combined features of acral erythema and hyperpigmentation due to oral tegafur.

Purpose: We evaluated the 3-month, postoperative clinical outcomes of patients implanted with refractive, aspheric, bifocal, Lentis Comfort (LS313-MF15, Oculentis) intraocular lenses (IOLs). Methods: Eighty-two eyes of 51 cataract patients underwent phacoemulsification and were implanted with LentisComfort IOLs. The uncorrected distant visual acuity (UCDVA), the 80-cm uncorrected intermediate visual acuity (UCIVA), the 40-cm uncorrected near visual acuity (UCNVA), and refractive values were evaluated 1 and 3 months postoperatively. At the latter time, defocus curves were drawn, contrast sensitivity tested, and satisfaction surveyed. Results: At the 3-month postoperative follow-up, the mean spherical equivalent was -0.12 ± 0.21 D; and the mean LogMAR UCDVA, 80-cm UCIVA, and 40-cm UCNVA were 0.02 ± 0.03, 0.13 ± 0.07, and 0.42 ± 0.10 respectively. The defocus curves revealed visual acuities in excess of 0.2 LogMAR at points between the distant and intermediate targets. The mean contrast sensitivity fell in the range of 90% of a normal population under both photopic and mesopic conditions. In terms of satisfaction, 71.8% of patients were satisfied or very satisfied, but about 20% reported dysphotopsia. Conclusions Implantation of the refractive, aspheric, bifocal, intraocular, LentisComfort in patients with cataracts improved both the distant and intermediate visual acuities by 3 months after surgery and the visual quality was comparable to that afforded by other IOLs both objectively and subjectively.
