Inflammatory pseudotumor-like follicular dendritic cell sarcoma with first clinical manifestation of thrombocytopenia: A case report.

Background: Inflammatory pseudotumor-like follicular dendritic cell sarcoma (IPT-like FDCS) is often associated with Epstein-Barr (EB) virus infection. The tumor is commonly found in the spleen and liver, and it has been reported in the literature that it can be associated with paraneoplastic pemphigus, myasthenia gravis, and other diseases. A case of IPT-like FDCS with clinical features of thrombocytopenia has not been reported.

[Burkitt's lymphoma of the spermatic cord: a case report and review of the literature].

Objective: To investigate the clinicopathological characteristics of primary Burkitt's lymphoma (BL) in the spermatic cord.

Methods: A case of BL of the spermatic cord was studied by histopathology and immunohistochemical techniques. The clinical data and the related literature were reviewed.

Endomorphin-1 is more potent than endomorphin-2 in inhibition of synaptic transmission in substantia gelatinosa of adult rat spinal cord.

Effects of endomorphin-1 (EM-1) and endomorphin-2 (EM-2) on synaptic trans-mission were investigated on neurons in substantia gelatinosa (SG) of the spinal dorsal horn. Both EM-1 (1 microM) and EM-2 (1 microM) remarkably reduced the frequency but not the amplitude of miniature excitatory postsynaptic currents (mEPSCs) and miniature inhibitory postsynaptic currents (mIPSCs). These effects were antagonized by beta-funaltrexamine (beta-FNA, 10 microM), a selective mu-opioid receptor antagonist.
