Spontaneously hypertensive rats (SHR) are widely used as a model of attention deficit hyperactivity disorder (ADHD) as their ADHD-like behaviors are restored by methylphenidate. However, a postnatal neural development in SHR is unknown. We performed whole cell patch clamp recordings from locus coeruleus (LC) neurons in neonatal [postnatal day (P) 3-5], juvenile (P21-28), and adult (P 49-56) SHR...

This study examined whether the calcium antagonist nisoldipine can shift the relations between sodium excretion, papillary blood flow, renal interstitial pressure, and renal perfusion pressure toward lower pressures in spontaneously hypertensive rats. Mean arterial pressure decreased similarly by 9% and 12% in Wistar-Kyoto and spontaneously hypertensive rats after nisoldipine (0.5 microgram/kg ...

This study examined whether the calcium antagonist nisoidipine can shift the relations between sodium excretion, papillary blood flow, renal interstitial pressure, and renal perfusion pressure toward lower pressures in spontaneously hypertensive rats. Mean arterial pressure decreased similarly by 9% and 12% in Wistar-Kyoto and spontaneously hypertensive rats after nisoidipine (0.5 /xg/kg bolus+...

Wistar rats were given a diet with 8% sodium chloride to induce hypertension and subsequently sacrificed. Glycine max powder was used reduce atenolol’s side effects during the trial. Thirty divided into five groups tested over eight weeks. Rats’ blood pressure (BP) measured tail-cuff NIBP monitor. Biochemical markers like TG, TC, HDL, LDL, VLDL, alanine transferase, aspartate lipid peroxide (LP...

Lymphocyte number and weight and their sodium and potassium contents and net passive fluxes were measured in spontaneously hypertensive stroke-prone rats, deoxycorticosterone acetate-treated rats, and two-kidney, one clip renal hypertensive rats. Wistar-Kyoto rats were used as controls for the spontaneously hypertensive stroke-prone rats, and normal intact Sprague-Dawley rats were used as contr...

The value of restenosis after percutaneous coronary intervention (PCI) is recognized worldwide, especially for diabetic patients. Interleukin-1/Toll-like receptor (IL-1/TLR) signaling is involved in innate and adaptive immune responses, but whether and how the IL-1/TLR-induced nuclear factor kappa B (NFκB) pathway plays key roles in intimal formation is unclear. The underlying mechanism of inti...

We have recently demonstrated that in large arteries of spontaneously hypertensive rats (SHR), there is no increase of stiffness despite the increase in wall thickness, a sign of mechanical adaptation of the arterial wall to the higher level of stress. Because the dense plaques of smooth muscle are a major site of anchorage between the muscle cells and extracellular matrix, we determined by ele...

This study was conducted to investigate the mitigation of dietary aflatoxin in Wistar rats using extract from selected phyto-antioxidant sources. A total one hundred and twenty weighing between 180-190g (80 females 40 males) at six weeks old were allotted eight treatments with 15 per treatment (10 5 males), a completely randomized design. The Treatment 1 (Normal diet + no aflatoxin), 2 (Aflatox...

The superior colliculus (SC), substantia nigra pars reticulata (SNPr), and striatum have been characterized as important structures involved in the modulation of seizure activity. In the current study, bicuculline (GABA(A) antagonist) and muscimol (GABA(A) agonist) were microinjected into the deep layers of either the anterior SC (aSC) or posterior SC (pSC) of genetically developed Wistar audio...
