A patient with basidiobolomycosis is reported,the clinical course described,the ultra- structural and histologic changes observed,and mycologic examination was made.The results indicated that:(1)In the course of using corticosteroids,because the inflammatory reaction was suppressed par- tially,the clinical manifestation was relatively relieved.In the loci the pathogenic fungi still grew well, and focal dissemination was observed;(2) In the course of using itraconazole,the drug exerted fungistatic and fungicidal action through the destruction of cell membranes of fungi.Meanwhile,itra- conazole also exerted a synergistic action with the defense function of the human body,resulting in an enhanced therapeutic effects.The strong acute inflammatory reaction was triggered by the destroyed fungi caused by itraconazole.Then the fungi were cleared,the lesions were absorbed and repaired.Sur- gical intervention may be helpful to remove abscesses and fibrous nodules formed in the clinical course, so as to shorten the course of treatment.

Objective The current study was designed to investigate the inhibitive effect of celastrol on the proliferation of acute myelogenous leukemia (AML) cells. Methods The effect of celastrol on AML cells in vitro was examined by MTT assay and flow cytometry (FCM). Results After the AML primary cells were treated with different concentrations of celastrol, the results were analyzed by MTT. The growth of the cells were significantly inhibited compared with the control group (P ＜0.01). The results detected by FCM showed that the apoptosis was seen after treated with celastrol with different concentration for different times.The apoptotic rates were significantly higher than that in the control group with statistical significance (P＜ 0.01).Conclusion Celastrol could inhibit the proliferation of AML cells in vitro, which may be associated with inducing cell apoptosis.

Objective To explore an ideal form of graft for pituitary transplantation, which could restore normal pituitary function and avoid hyperprolactinmia providing it is implanted outside the hypophysiotrophic area.Methods Pituitary cells, hypothalamic cells and nigral cells were obtained from human embryos (4-6 months gestation) during therapeutic abortion, and three different cultures were conducted: group P (n=38), half amount of pituitary cells per embryo; group PH (n=18), half amount of pituitary cells mixed with double amount of hypothalamic cells obtained from each embryo; and group PHN (n=20), half amount of pituitary cells mixed with double amount of hypothalamic and nigral cells acquired from each embryo. The histological changes of the cultured cells were observed and the secretive levels of growth hormone and prolactin indifferent medium were measured.Results All the monolayer cultured cells grew well throughout the 30-day culture period. Ultrastructurally, the cells in group P degenerated significantly at the 21st day of culture. However, in the PH and PHN groups, the cells kept well viability. The secretive level of growth hormone in culture medium declined steadily in group P, but kept at 20 ng/ml in both PH and PHN groups. Prolactin concentration decreased rapidly following an initial increase in group P, but kept at a high level in PH group. In PHN group, the prolactin level was valuable, remaining at about 15 ng/ml.Conclusions In the mixed culture of fetal pituitary-hypothalamic-nigral cells, the pituitary cells kept high viability in a long period and its hormone secretion remained at ideal levels. These indicate that the mixed fetal pituitary-hypothalamic-nigral cells are a good graft, which can be implanted outside the cranium while maintaining normal pituitary function with no increase in blood prolactin concentration.
