1.Study on the Culture of Mycelial Phase of Pityrosporum Orbiculare
Chinese Journal of Dermatology 1994;0(06):-
In order to investigate some requisite conditions for the formation of mycelial phase of Pityrosporum orbiculare (P. orb) and understand indirectly the pathogenesis of tinea versicolor, we used a semisolid medium containing cholesterol 1. 0g/dl and agar 0.8g/dl, and obtained the mycelial phase of P. orb. Then we studied the relationship between the formation of the mycelial phase and the concentration of cholesterol or agar in the medium. The results showed that when P. orb were cultured on the medium, the hyphae began to grow on the 4-6th day, increased gradually, and peaked on the 10-12th day. The hyphae were mostly blastohyphae, 8-16?m in length and in the shape of racket,and distributed in clustes. It was found that 0. 25g/dl was the minimum concentration of cholesterol to induce the mycelial phase in vitro. Within the range of 0. 25-1.0g/dl the higher the concentration was, the more the hyphae were. When the concentration exceeded 1.0g/dl, the hyphae did not increase markedly. Relative high moisture (0.8g/dl of agar in the medium) was suitable for the production of the hyphae. The results suggest that the occurrence and recurrence of tinea versicolor in summer probably relate to the change of choleserol concentration on the surface of the skin after the evaporation of sweat.

Objective To investigate the effect of the balance between helper T lymphocyte (Th) 1 cytokines and Th2 cytokines in the serum of hepatic fibrosis rats induced by CCl4 on the expression of β-catenin in their livers. Methods Seventy-five rats were divided into control group,treatment group and model group. Hepatic fibrosis models were built by subcutaneous injection of CCl4in male Wistar rats, then rats in treatment group were treated with pentoxifylline(PTX) by intragastric administration. The model rats without PTX treatment served as treatment control. The serum levels of Th1 cytokines(interferon-γ, IFN-γ; tumor necrosis factor-α, TNF-α), Th2 cytokines (interleukin-4,IL-4;interleukin-6,IL-6) and type Ⅳ collagen were measured by enzyme-linked immunosorbent assay (ELISA). The expression and distribution of β-catenin in liver tissue and the percentage of area of type Ⅳ collagen accounted in the liver were analyzed by immunohistochemical analyses. The changes in serum cytokines were depicted by using One-way ANOVA, and the correlation between β-catenin expression and cytokines levels or hepatic fibrosis development was elucidated by Bivariate.Results The serum levels of Th2 cytokines in model group were significantly higher than those in treatment group, and even higher than those in control group (F=71. 260,91. 732, all P<0.05).However, the levels of Th1 cytokines in model group were significantly lower than in treatment group while even lower than those in control group(F= 50. 420,10. 625, all P<0.05). Serum cytokines came out to be Th2 polarized. Meanwhile, the percentage of type Ⅳ collagen area accounted in the liver,which was corresponding to the degree of liver fibrosis, was lower in the treatment group than the model group and even lower in control group (F=3 000,both P<0.05). β-catenin expression in the liver of model group was stronger than that in the treatment group, and even stronger than that in normal group (F=92. 030, both P<0. 05). According to β-catenin immunohistochemical analyses based on patho-photos, livers from the model group showed dark color in both cell cytoplasm and nucleus, while the liver from the treatment group only showed weak color in cytoplasm and no straining color in nucleus and the liver from normal group showed colors neither in cytoplasm nor in the nucleus.The expression of β-eatenin had a positive correlation with either the level of Th2 cytokines in serum of rats (r=0. 560,P<0.01) or the percentage of area of type Ⅳ collagen accounted in the liver of rats (r=0. 757, P<0. 01). Conclusions Th2 polarization in serum cytokines can aggravate the development of liver fibrosis by inducing the expression of β-catenin, which in the livers of rats is a reflection of the degree of the liver fibrosis.

Objective To observe the effects of phenytoin and gabapentin in therapeutic dosage on low-dose veratridine-induced epileptiform discharge in rats' hippocampal CA1 neurons,and explore the involved mechanisms.Methods By means of whole-cell patch clamp technique,the epileptiform discharge model of rats' hippocampal CA1 neurons was constructed with extracellular perfusion of 0.5?mol/L veratridine,and the model should be regarded as successfully estabilshed if bursting discharge emerged within 30min perfusion.The effects of phenytoin(2.5,5,10 and 15?mol/L) and gabapentin(2.5,5 and 10?mol/L) on the epileptiform activity were observed under the voltage-clamp configuration,and the current changes for 1 hour in CA1 neurons was also observed.Results Nine-sixteen minutes after veratridine perfusion,the huge,rhythmic slow oscillation emerged,with 100~200Hz high-frequency discharge,in the hippocampal CA1 neurons,which was similar to the paroxysmal depolarization shifts(PDS),implying that the epileptiform activity was reproduced.Therapeutic dose of phenytoin blocked the veratridine-induced epileptiform activity.The bursting interval of the epileptiform activity was prolonged along with the increased phenytoin concentration,and the duration of bursting was not shortened.1h current decreased gradually in the generation of veratridine-induced epileptiform activity.Therapeutic dose of gabapentin did not block the epileptiform activity in this model.Conclusions In the epileptiform discharge model of rats' hippocampal CA1 neurons,phenytoin can block the epileptic activity in a dose-dependent manner,and the effect may be related to the inhibition of 1h currents.Gabapentin shows no influence on the epileptiform activity,and the possible mechanism may be its ineffectiveness to the persistent sodium currents,and vertridine-induced epileptiform activity does not enhance the 1h currents.

Objective To observe the effects of low dose of veratrine on the discharges of rat hippocampus pyramidal neurons,and to elucidate its possible cytological mechanism.Methods The discharge features of hippocampus CA1 pyramidal neurons of 14-day-aged healthy Sprague-Dawley rats induced by low dose(0.3~0.8?mol/L)of veratrine were observed by slice patch-clamp technique.Presynap- tic stimulation was given to Schaffer collaterals.Presynaptic receptor inhibitors such as 6-cyano-7-nitroquinoxaline-2,3-dione(CNQX, 5?mol/L),DL-2-amino-5-phosphonopentanoic acid(AP-5,12.5?mol/L),bicuculline(Bic,10?mol/L)and tetrodotoxin(TTX,40~80nmol/L)were used to investigate the influence on veratrine-induced epilepsy andⅠ-Ⅴcurves were plotted under these conditions.Elec- trophysiological mechanism of veratrine-induced epilepsy was elucidated on the basis of these experiments,Results After a perfusion with low dose of veratrine,the pyramidal neurons were found to discharge relatively fixed-mode slow wave epileptoid bursts accompanied with hyperpolarization of membrane potential.These epileptoid bursts were not blocked by a mixture of CNQX,AP-5 and Bic,but by low dose of TTX.After a perfusion with veratrine,Ⅰ-Ⅴrelationship tended to be nonlinear and the depolarization rectification was enhanced,which were reversed by administration of low dose of TTX.The subthreshold TTX-sensitive persistent sodium current of CA1 pyramidal cells was enhanced by veratrine in a voltage-dependent manner.Conclusion Inducing slow wave epileptoid bursts,the low dose of veratrine can remarkably change the discharge features of CA1 pyramidal neurons.Such epileptoid activities were not influenced by the synaptic receptor inhibitors,and were obviously related to the persistent sodium current.
