A survey for nematode and cestode parasites of rodents in Korea has been carried out at the areas of Chulwon, Kumwha, Pochon, Paju and Chungpyong, Kyunggi-Do. A total of 300 rodents of seven species was examined, comprising of 219 A. agrarius, 33 R. norvegicus, 8 R. alexandrinus, 14 Mus musculus yamashinai, Microtus fortis pellceus, 21 Crocidura russula and a Cricetulus trition nester. The following fifteen species belonging to thirteen genera were identified: NEMATODA: Heterakis spumosa, Syphacia obvelata, Nippostrongylus muris, Protospirura muris, Capillaria hepatica, Capillaria sp., Heligmosomum sp., Heligmosomoides sp., Rictularia sp. and Gongylonema sp. CESTODA: Hymenolepis nana, Hymenolepis diminuta, Raillietina coreensis, Paranoplocephala sp. and Cysticercus fasciolaris(the larva of Taenia taeniaeformis).

A parasitological study was performed with 452 malaria patients evacuated from South Vietnam by examinations of their peripheral blood. Results were as follows: The peripheral blood examinations revealed that 52.0% of the examined have parasitemia, of which 95.3% was P. falciparum, one case of P. vivax and the other 10 patients were mixed infected. Neither P. malaria nor P. ovale were found. A total of 1,500 thick and thin blood films was prepared and 707 slides of them (47.1%) showed positive. In P. falciparum, ring forms were found most frequently and the next was gametocytes. Eighty slides (50%) showed mixed together with both ring form and gametocytes. All of the erythrocytic stages were seen in three slides of P. vivax. Weekly periodical examinations showed 233.8 parasite density every 1,000 W.B.C count in average, while occasional at fever attacks 531.7.Size of gametocytes in P. falciparum was 9.31(+/-0.89) by 2.16(+/-0.53) in macrogametocyte and 6.61(+/-0.82) by 2.51(+/-0.35) in microgametocyte. Their sex ratio was 100 : 92. Repeated blood examinations showed increased detection rates. The positive rate of parasitemia was 52.0% in single examination, increasing in succession with repetitions.

Hamartoma is a very rare congenital tumor. A few cases of hamartomatous pol yps in the stomach were reported. Most of harrurtomatous polyps in the stomach occur in patients of polyposis coli. We have experienced four cases of gastric hamartomatous polyps without polyposis coli. There are some differences between previously reported cases and ours. In our casee, the distribution of age is from fourth to ninth decade, men and women ratio is 1: 1. The number of polyps are one in three cases and two in one case. The size of polyps is from 5mm to 12 mm. The location of polyps are various, but most common in antrum. We have experienced four cases which were different from previously reported ones and report them with a brief review of literatures.

Angioleiomyoma is an infrequent benign smooth muscle tumor that arises from smooth muscle cells of arterial or venous walls in the tunica media layer. It would be found in the dermis, the subcutaneous tissue, or the superficial fascia of the anywhere in the body and is most often seen in the lower extremities. The typical lesion is a small, slowly growing, round, but firm and mobile nodule. We report a case of angioleiomyoma located on the anterior aspect of the elbow, which was mistaken for extradigital glomus tumor after history taking, physical examination. With point tenderness and worsening sharp pain in cold exposure for several years, the patient was referred for a further evaluation, and the lesion was 5 mm sized well-circumscribed mass in the anterior elbow with vascular signals on color and power Doppler by ultrasonography and finally diagnosed as angioleiomyoma following complete excision and histological evaluation.

Mesenteric panniculitis (MP) is non-specific inflammation of the adipose tissue that primarily involves the small bowel mesentery. Omental involvement has been rarely reported but we report a case of 25 years old woman with isolated lesser omental panniculitis. This patient was diagnosed by CT findings and recovered completely with conservative treatment. Invasive diagnostic methods or surgical exploration has been used to diagnose MP. However, all six reported cases of omental panniculitis including the current case showed a benign course; therefore, awareness of the CT findings is essential for the best diagnosis and management of omental panniculitis.

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are severe, diffuse mucocutaneous reactions that can be elicited by drugs, infection, malignancy, and herbal supplements. A wide variety of mucocutaneous events, such as systemic contact dermatitis, have been reported to be elicited by Rhus chicken, although cases of SJS and TEN are rare. Here, we present a case of SJS caused by Rhus-chicken ingestion. A 48-year-old man who wanted to improve his health and treat a gastrointestinal problem ingested Rhus chicken in the traditional manner. Twenty-four hours later, he developed a multiple erythematous maculopapular skin rash with vesicles and bullaes on 30% of the body surface and multiple erosions on the lips. He was diagnosed with SJS/TEN and showed characteristic clinical findings induced by Rhus chicken. After the patient stopped Rhus-chicken ingestion and received methylprednisolone and antibiotics, his symptoms, signs, and laboratory findings improved. With this case, we emphasize that SJS and TEN can occur after ingesting Rhus chicken, although the incidence is very low.

Soybean polyunsaturated phosphatidylcholine (PC) is thought to exert anti-inflammatory activities and has potent effects in attenuating acute renal failure and liver dysfunction. The aim of this study was to investigate the effects of PC in protecting multiple organ injury (MOI) from lipopolysaccharide (LPS). Six groups of rats (N=8) were used in this study. Three groups acted as controls and received only saline, hydrocortisone (HC, 6 mg/kg, i.v.) or PC (600 mg/kg, i.p.) without LPS (15 mg/kg, i.p.) injections. Other 3 groups, as the test groups, were administered saline, HC or PC in the presence of LPS. Six hours after the LPS injection, blood and organs (lung, liver and kidney) were collected from each group to measure inflammatory cytokines and perform histopathology and myeloperoxidase (MPO) assessment. Serum cytokines (TNF-alpha, IL-6 and IL-10) and MPO activities were significantly increased, and significant histopathological changes in the organs were observed by LPS challenge. These findings were significantly attenuated by PC or HC. The treatment with PC or HC resulted in a significant attenuation on the increase in serum levels of TNF-alpha and IL-6, pro-inflammatory cytokines, while neither PC nor HC significantly attenuated serum levels of IL-10, anti-inflammatory cytokine. In the organs, the enhanced infiltration of neutrophils and expression of ED2 positive macrophage were attenuated by PC or HC. Inductions of MPO activity were also significantly attenuated by PC or HC. From the findings, we suggest that PC may be a functional material for its use as an anti-inflammatory agent.
