Gossypol was administered in Goya olive oil to low protein-fed (LP, protein-malnourished) and normal protein-fed (NP, control) adult male albino Wistar rats for 4 and 8 weeks at 20 mg/kg body weight/rat/day. At the end of the experiment, the rats were killed and blood was drawn from the rats by cardiac puncture and subjected to hematological and biochemical analyses. The data obtained were analyzed by two-way analysis of variance (ANOVA). The interaction of the treatments produced significant effects on serum levels of sodium, potassium, cholesterol, triglyceride, urea, glutamate oxalate transaminase, glutamate pyruvate transaminase, amylase and blood platelet count (P < 0.001), and uric acid (P < 0.01). Significant effects were produced on serum phosphate, albumin and blood reticulocyte count (P < 0.05) but not on packed cell volume, red blood cell count, white blood cell (WBC) count and WBC differential counts, hemoglobin concentration, creatinine, creatinine phosphokinase and alkaline phosphatase (P < 0.05). The administration of gossypol reduced the level of transaminases, cholesterol and uric acid in LP and NP rats, increased the levels of triglycerides, amylase, platelet and reticulocyte count in LP rats but decreased them in NP rats. The implications of the findings are discussed.

An Underlying Mechanism for the Altered Hypoglycemic Effects of Nateglinide in Rats with Acute Peripheral Inflammation.
Biol Pharm Bull

Graduate School of Medicine, Dentistry and Pharmaceutical Sciences, Okayama University, Okayama 700-8558, Japan.
The hypoglycemic effects of nateglinide (NTG) were examined in rats with acute peripheral inflammation (API) induced by carrageenan treatment, and the mechanisms accounting for altered hypoglycemic effects were investigated. NTG was administered through the femoral vein in control and API rats, and its plasma concentration profile was characterized. The time courses of the changes in plasma glucose and insulin levels were also examined.

The T22 protocol is an animal model of forced internal desynchronization, in which rats are exposed to an 11:11 light-dark (LD) cycle. This non-invasive protocol induces the dissociation of circadian rhythms in adult rats, making it possible to study the effects of circadian disruption on physiological and behavioral processes such as learning, memory, and emotional responses. However, the effects of circadian dissociation during other developmental stages, such as adolescence, remain unexplored.

Reactive oxygen species (ROS) produced by NADPH oxidase promote contraction of peripheral arteries, which is especially pronounced in early postnatal period in comparison to adulthood, but the mechanisms of such vasomotor influence are poorly understood. We tested the hypothesis that Rho-kinase and protein kinase C (PKC) mediate procontractile influence of NADPH oxidase derived ROS in peripheral artery of early postnatal rats. In addition, we evaluated the involvement Src-kinase and L-type voltage-gated Ca channels (LTCC) into procontractile influence of ROS, produced by NADPH oxidase, because of their known interplay with Rho-kinase and PKC pathways.

Background: Acute systemic inflammation affects many organs and it occurs in a wide range of conditions such as acute lung injury (ALI). Inflammation-triggered oxidative pathways together with the caspase activation seen in ALI, result in apoptosis. Dapagliflozin (DPG) is an agent that is known to have oxidative stress-reducing and anti-inflammatory effects in many tissues.

Secondary brain damageafter traumatic brain injury (TBI) involves oxidative stress, neuroinflammation, apoptosis, and necroptosis and can be reversed by understanding these molecular pathways. The objective of this study was to examine the impact of tasimelteon (Tasi) administration on brain injury through the nuclear factor erythroid 2-related factor 2 (NRF-2)/heme oxygenase-1 (HO-1) and receptor-interacting protein kinase 1 (RIPK1)/receptor-interacting protein kinase 3 (RIPK3)/mixed lineage kinase domain-like (MLKL) pathways in rats with TBI. Thirty-two male Wistar albino rats weighing 300-350 g were randomly divided into four groups: the control group, trauma group, Tasi-1 group (trauma + 1 mg/kg Tasi intraperitoneally), and Tasi-10 group (trauma + 10 mg/kg Tasi intraperitoneally).
