BACKGROUND: Intimal hyperplasia (IH) is the most common indicator for secondary intervention in peripheral vascular disease. Matrix metalloproteinases (MMPs) play a role in IH development due to their degradation of the extracellular matrix. Doxycycline, a member of the tetracycline family of antibiotics, is a potent MMP inhibitor. We have previously shown doxycycline inhibits MMP activity and VSMC migration in vitro. We hypothesized that doxycycline would decrease MMP activity in vivo and inhibit the development of IH in a rodent model of vascular injury...

It is high incidence of tubulointerstitial lesion (TIL) in lupus nephritis (LN) and TIL can affect the prognosis of patients with LN. Signal transducer and activator of transcription (STAT) 3 was activated in LN and STAT3 inhibition could delay the onset of LN. Here, we evaluated the role of a well-known STAT3 inhibitor, S3I-201, on TIL in lupus nephritis. STAT3 was activated in MRL/lpr mice (a mouse model of lupus nephritis), and treatment with S3I-201 inhibited the activation of it. The level of 24-h urine protein and nitrogen urea increased in MRL/lpr mice and adminstration of S3I-201 reduced the level of urinary protein...

Risperidone is an atypical antipsychotic agent that was originally approved by the United States Food and Drug Adminstration for the treatment of schizophrenia. There are many side effects that are frequently associated with the use of risperidone. These include weight gain, anxiety, extra-pyramidal side effects, and elevated prolactin levels. More infrequently, the use of risperidone has been linked to leukopenia. We will now present the case of a 66-year-old gentleman who developed leukopenia after the initiation of risperidone to control agitation due to delirium...
