Rats immunized with a semipurified preparation of the Escherichia coli heat-stable (ST) enterotoxin conjugated with a protein carrier were protected against challenge with semipurified or purified ST and viable organisms of multiple heterologous serotypes that produce only ST (LT-/ST+), but they were not protected against heal-labile (LT) toxin or viable strains which produce LT either alone (LT+/ST-) or together with ST (LT+/ST+).

Despite the established link between chronic high salt diet (HSD) and an increase in gut inflammation, the effect of HSD on the integrity of the intestinal barrier remains understudied. The present study aims to investigate the impact of HSD on the intestinal barrier in rats, encompassing its mechanical, mucous, and immune components. Expression levels of intestinal tight junction proteins and mucin-2 (MUC2) in SD rats were analyzed using immunofluorescence.

Objectives: Investigating the effect of melatonin (MLT) on the pharmacokinetics and related neurotransmitter and amino acid metabolism of vigabatrin (VGB) in epileptic rats in vivo.
Methods: High performance liquid chromatography was used to examine the pharmacokinetics and tissue distribution of VGB after intragastric administration dosing (50,100,200) mg/kg singly or in combination with melatonin (20 mg/kg) in rats. The single-compartment model of first-order elimination was fitted with the nonlinear mixed-effect model of first-order estimation.

Maternal immune activation (MIA) induces long-term cognitive impairments by modulating the gamma-aminobutyric acid (GABA)ergic system. Experimental evidence suggests that maternal immune challenge with bacterial active ingredient lipopolysaccharide (LPS) reduces GABAergic tone in the offspring's prefrontal cortex. In this study, we aimed to assess whether interleukin-6 (IL-6) contributes to this reduced GABAergic system in the prefrontal cortex of juvenile offspring.

Ischemia-reperfusion injury (IRI) is a major obstacle in liver transplantation, especially with steatotic donor livers. Dysbiosis of the gut microbiota has been implicated in modulating IRI, and plays a pivotal role in regulating host inflammatory and immune responses, but its specific role in liver transplantation IRI remains unclear. This study explores whether can mitigate IRI and its underlying mechanisms.

Ethnopharmacological Relevance: Bovis calculus (BC) has a medicinal history of over 2,000 years in treating stroke in China. Bovis Culus Sativus (BCS) has similar pharmacological effects to BC. Due to the scarcity of BC, BCS is often used as a substitute for BC in clinical practice for treating stroke in traditional Chinese medicine.
