Aim To study the expression of caspase-12 mRNA and protein following focal cerebral ischemia-reperfusion in rats,and explore the effect of endoplasmic reticulum pathway on neuronal apoptosis.Methods 60 male Wistar rats were randomly divided into sham-operated group and ischemic group.The middle cerebral artery occlusion(MCAO)models were established by using the intraluminal suture occlusion method,neuronal apoptosis was detected by TUNEL staining,the expression of caspase-12 protein was detected by immunohistochemical staining,the expression of caspase-12 mRNA was detected by RT-PCR method.Results In ischemic group,the number of apoptotic cells and the expression of caspase-12 mRNA and protein were gradually increased following prolonged cerebral reperfusion,reached the peak at 24 h.The number of apoptotic cells and the expression of caspase-12 mRNA and protein in ischemic group were significantly less than those of sham-operated group at all times(P

We report, herein, a case of reactive perforating collagenosis in a 52-year-old man with diabetes mellitus and chronic renal failure on hemodialysis. He had multiple, pinhead to pea sized, round or oval shaped, central umbilicated papules on the face, trunk, and extremities for 3 months duration. The papules developed after scratching due to pruritus. Histopathologic examination showed a cup-shaped depression of the epidermis filled with parakeratotic material, necrobiotic collagen and inflammatory cells. At the base of the depression, the epidermis showed interruption through which basophilic bundles of collagen ex-tend in a vertical direction from the dermis. The skin lesions improved after treatment with oral antihistaminics:

A clinical analysis was done on 134 cases with bronchial asthma who were admitted to the Department of Pediatrics Yeungnam University from May 1987 to October 1991. The results were as follows: 1) The peak age of bronchial asthma was under 2 years. The sex ratio of male to female was 2.9:1. 2) The outbreak of bronchial asthma was most common in fall, especially in September. 3) The past history of other allergic diseases were present in 22.4% of patients (30/134 cases), and the previous bronchiolitis in infancy were experienced in 12.7% of patients (17/134 cases). 4) According to the skin test for allergens done by RAST, the most common allergens were Mites and House dust. 5) Eosinophilia (T.E.C>250/min) was found in 29.1%t of patients, and elevated lgE level (>200 IU/ml) was found in 63.2% of patients. 6) No significant differences in the serum lgE level were found between male and female patients. No significant differences in the serum lgE level were found between asthma patients with and without other allergic diseases. 7) The serum lgE level of school aged patients was significant higher than that of preschool aged (p<0.01).

An experimental studies were carried out to observe the protective effects of malotilate, a new antihepatotoxic agent, on the chronic hepatic injury induced by CCl4 with or without ethanol. The rats used weighed about 200g were divided into 2 groups, 4 weeks & 8 weeks. Each group was given by orally with malotilate, 100 mg/kg, once a day, and was injected by subcutaneously with CCl4 1.5 mg/kg in a mixture with olive oil twice a week. Aqueous ethanol (20%) was administered in drinking water daily. The serochemical and histopathological studies were carried out in each experimental group. The results were as follows: 1. The chronic liver injuries induced by CCl4 with or without ethanol were significantly ameliorated by normalize serum values GOT, GPT. Alkaline phosphatase, Cholesterol, HDL-Cholesterol, and gamma glutamyl transpeptidase. 2. In Group of 4 weeks, malotilate manifested protective effects by significant inhibition of fatty changes, spotty necrosis and fibrosis in CCl4-intoxicated liver with or without additional ethanol. 3. In group of 8 weeks, malotilate significantly imoproved fatty changes, fibrogenic activity in the group administered with CCl4, followed by ethanol.

OBJECTIVETo analyze the fungal composition in Massa Medicata Fermentata based on culture dependent method and independent PCR-SSCP technique.
METHODFungi were directly isolated from Massa Medicata Fermentata samples. The obtained strains were identified according to morphology and DNA sequence. Meanwhile the total fungal DNA was extracted from Massa Medicata Fermentata samples, the cultural independent PCR-SSCP technique based on β-tubulin gene were used to identify the mycobiota.
RESULTAccording to cultural method, Aspergillus flavus and Rhizopus oryzae were present in Massa Medicata Fermentata samples, while A. flavus and A. niger were present in fried Massa Medicata Fermentata samples. In contrast, 5 species were obtained by PCR-SSCP technique, A. flavus was overlapped with fungal taxa derived from culture dependent method; A. ambiguu and A. s ivoriensis were dominant with relative abundance of 57% and 35% respectively, while the relative abundance of A. flavus was as low as 4%. None species was obtained from fried Massa Medicata Fermentata samples.
CONCLUSIONPCR-SSCP based on β-tubulin gene could distinguish fungi into species, culture dependent method combined with culture independent method could better understand the fungal composition associated with Massa Medicata Fermentata fermentation.

Three compounds were isolated from solid culture of endophyte Myrothecium roridum IFB-E091 in Artemisia annua. Their structures were determined as (S)-(-)-N-[2-(3-hydroxy-2-oxo-2,3-dihydro-1H-indol-3-yl)-ethyl]-acetamide (1), N-(4-hydroxyphenethyl)acetamide (2) and asperfumoid (3), in which compound 1 was a new indole derivative. In cytotoxicity assay, the compound 1 had no obvious inhibition activity in human hepatoma cell line SMMC-7721 and human cervical carcinoma cell line HeLa.
