Human seminal plasma inhibits brain nitric oxide synthase activity.
Nitric oxide is a chemical messenger which functions as a neurotransmitter or as a cytotoxic agent. Nitric oxide synthase (NOS) has been isolated from various mammalian reproductive tissues. The presence or absence of NOS in spermatozoa has not yet been reported. We therefore tested human and murine spermatozoa for NOS activity by measuring the conversion of arginine to citrulline. No activity ...
متن کاملThe Fibrinolytic Pathway of Human Plasma
The conversion of the plasminogen proactivator to plasminogen activator by activated Hageman factor or its fragments has been recognized as an essential step in the conversion of plasminogen to plasmin. The plasminogen proactivator has been completely separated from prekallikrein and pre-PTA, two other proenzyme substrates of activated Hageman factor or its fragments. Plasminogen proactivator, ...
متن کاملHuman seminal plasma allergy and successful pregnancy.
Human seminal plasma allergy in women is an uncommon phenomenon. A great variety of reactions ranging from local swelling to generalized systemic reactions have been described, and local symptoms have often been misdiagnosed as chronic vulvovaginitis. Sperm barriers, such as condoms, are the most widely advocated method for avoiding these reactions; however this is not acceptable to couples who...
متن کاملFibronectin fragments in human seminal plasma.
The study has revealed the presence of fibronectin (FN) fragments and a lack of intact FN in 72 seminal plasma samples. The FN fragmentation was examined by immunoblotting with a monoclonal antibody specific to the central cellular FN domain and was confirmed with a monoclonal antibody directed to the C-terminal domain of FN. Nine FN fragments between 60 and 200 kDa and five fragments of 60-150...
متن کاملDouble Stranded RNA in Human Seminal Plasma
Recently, human semen was shown to contain cell-free nucleic acids, such as DNA, long single stranded RNA, and small RNAs-miRNA and piRNA. The RNAs have been suggested to have potential biological roles as communication molecules between cells and in the temporal and spatial regulation of gene expression in the male reproductive system. Here we demonstrate that human seminal plasma contains a v...
