We examined changes in mRNA expression patterns for proinflammatory cytokines and growth factors in blood samples after application of a tourniquet to the rat hind limb. Slight upregulations of interferon (IFN)-gamma, macrophage colony-stimulating factor (M-CSF) and transforming growth factor (TGF)-beta1 mRNA began at 2h after tourniquet application and(More)
We have developed a sensitive and specific polymerase chain reaction (PCR) method for identifying phytoplankton in cases of death by drowning, and we have designed four primer pairs, EG1, EG2, SK1 and SK2, for chlorophyll-related genes of Euglena gracilis and Skeletonema costatum, which are commonly distributed in all types of water. In order to evaluate(More)
We studied temporal changes in mRNA expression patterns for nitric oxide synthase (NOS), cytokines, neurotrophins and neurotrophin receptors in the dorsal root ganglion (DRG) of the rat, after application of a tourniquet to the hind limb. Collapsed myelin and degenerated axons were observed in the tourniquet segment of the sciatic nerve. Gene expression(More)
The release of a tourniquet after hind limb ischemia results in vital organ injury, which progresses to multiple organ failure with a high mortality rate. Many events are involved in ischemia-reperfusion (I/R) injury. The purpose of this study was to determine how IL-6 or iNOS is involved in I/R injury using IL-6 knockout (KO) and iNOS KO mice.

We present a new PCR method for identifying plankton in cases of death by drowning. We designed four primer pairs for chlorophyll-related genes of Euglena gracilis (EG) and Skeletonema costatum (SK), which are commonly distributed in water. The primers were selected from sequences coding chloroplast/chlorophyll apoprotein of EG (EG1 and EG2) and(More)
We have developed a sensitive and specific PCR method for detecting plankton DNA in cases of death by drowning. However, this PCR method could not be used for cases of drowning in water containing no plankton. Bacteria species are normally localized in the throat and trachea and they may invade into blood through the respiratory tract in people who have(More)
We investigated the mRNA levels of neuronal, inducible, endothelial nitric oxide synthases (nNOS, iNOS, eNOS) and tumor necrosis factor-alpha (TNF-alpha) in a rat dorsal root ganglion (DRG) after tourniquet application to a hind limb to identify molecules that trigger secondary events after peripheral nerve injury. Significantly high nNOS, iNOS mRNA and(More)
Cisplatin (CDDP), a major chemotherapeutic agent used to treat solid tumors, is known to induce acute renal failure (ARF). The progression of tissue injury involves the coordination of inflammatory and repair responses. Interleukin-6 (IL-6) has been suggested to modulate inflammatory and repair processes in various tissue injuries. In this study, we(More)
AIMS Cisplatin, a major chemotherapeutic agent, accumulates in proximal tubules of the kidneys and causes acute renal failure dose-dependently. We previously reported that cisplatin induced more severe renal dysfunction in interleukin-6 (IL-6) knockout (IL-6(-/-)) mice than in wild-type (WT) mice. Expression of a pro-apoptotic protein was significantly(More)
AIMS We reported that interleukin-6 (IL-6) plays a protective role in the development of cisplatin-induced acute renal failure (ARF) through upregulation of anti-oxidative stress factors. In this study, we examined the effects of dimethylthiourea (DMTU), a hydroxyl radical scavenger, on the development of cisplatin-induced ARF in wild-type (WT) and(More)
