Impact of Azithromycin on Forsythiaside Pharmacokinetics in Rats: A Population Modeling Method.

Objective: Lianhuaqingwen and Shuanghuanglian are drug treatment options for Corona Virus Disease 2019 (COVID-19). In China, use of traditional Chinese medicine with Shuanghuanglian or Lianhuaqingwen (for them, forsythiaside is the active antiviral and antibacterial component) in combination with azithromycin is common for the treatment of pediatric pneumonia. It is important to understand the reason why the combination of these compounds is better than a single drug treatment.

Impact of Electroacupuncture Stimulation on Postoperative Constipation for Patients Undergoing Brain Tumor Surgery.

Background: Constipation is frequently encountered in patients undergoing brain tumor resection. Constipation has negative effects on daily living, well-being, and individuals' quality of life. We examined the impact of acupuncture and electroacupuncture (EA) stimulation on postoperative constipation for patients undergoing brain tumor resection.

Pharmacokinetic interaction of Forsythia suspensa extract and azithromycin injection after single and co-intravenous administration in rats.

Azithromycin and Chinese medicine forsythia are often used together to treat pediatric mycoplasma infections in China. We aimed to investigate the pharmacokinetic interaction of Forsythia suspensa extract and azithromycin after single and co-intravenous administration in rats. Male Sprague-Dawley rats received single (Forsythia suspensa extract or azithromycin) treatment or co-administration of Forsythia suspensa extract and azithromycin.

Pharmacokinetic interaction between shuanghuanglian and azithromycin injection: a nonlinear mixed-effects model analysis in rats.

1. This study aimed to evaluate the pharmacokinetic interaction of shuanghuanglian (SHL) and azithromycin in rats, and to provide experimental support for rational drug use in clinics. 2.

Alterations of amino Acid level in depressed rat brain.

Amino-acid neurotransmitter system dysfunction plays a major role in the pathophysiology of depression. Several studies have demonstrated the potential of amino acids as a source of neuro-specific biomarkers could be used in future diagnosis of depression. Only partial amino acids such as glycine and asparagine were determined from certain parts of rats' brain included hippocampi and cerebral cortex in previous studies.

Development and validation of a highly sensitive LC-ESI-MS/MS method for the determination of hyperoside in beagle dog plasma: application to a pharmacokinetic study.

A highly sensitive, rapid assay method has been developed and validated for the analysis of hyperoside in beagle dog plasma with liquid chromatography coupled to tandem mass spectrometry with electrospray ionization in the positive-ion mode. The assay procedure involves extraction of hyperoside and ginsenoside Re (IS) from beagle dog plasma. Chromatographic separation was carried out on an Agilent Zorbax XDB-C18 (100 × 2.

Altered plasma and brain disposition of isopropylidene shikimic acid liposome in rats and the brain protection in cerebral ischemia-reperfusion.

Context: Cerebral ischemia-reperfusion (I/R) injury is a secondary injury caused by oxidative stresses and inflammatory responses after recovery from cerebral ischemia. Brain protective drugs were used to reduce the injury. In order to improve the distribution in brain and enhance the brain-protective efficacy, some pharmaceutical technologies were used to achieve brain targeting delivery.
