Two out of 52 home-slaughtered pigs (3.8%) were infected with a fertile lung cyst each; both cysts were also identified as E. ortleppi. Microscopic examination revealed 10/289 dog faecal samples to contain taeniid eggs, of which four samples (two each) contained Echinococcus canadensis (G6/7) or Taenia hydatigena, respectively. This is the first insight in the Echinococcus species circulating in Zambia providing premises for further studies into transmission dynamics of CE in the southern African region.Tissue plasminogen activator (tPA) has been shown to prevent steroid-induced reduction in aqueous humor outflow facility via an upregulation in matrix metalloproteinase (Mmp) expression. The purpose of this study was to determine whether tPA can rescue outflow facility reduction in the Tg-MYOCY437H mouse model, which replicates human juvenile open angle glaucoma. Outflow facility was measured in Tg-MYOCY437H mice following periocular steroid exposure and intraocular protein treatment with enzymatically active or enzymatically inactive tPA. Effects of tPA on outflow facility were compared to those of animals treated with topical sodium phenylbutarate (PBA), a modulator of endoplasmic reticulum stress. Gene expression of fibrinolytic pathway components (Plat, Plau, and Pai-1) and matrix metalloproteinases (Mmp-2, -9, and -13) was determined in angle ring tissues containing the trabecular meshwork. Tg-MYOCY437H mice did not display further outflow facility reduction following steroid exposure. Enzymatically active and enzymatically inactive tPA were equally effective in attenuating outflow facility reduction in Tg-MYOCY437H mice and caused enhanced expression of matrix metalloproteinases (Mmp-9 and Mmp-13). tPA was equally effective to topical PBA treatment in ameliorating outflow facility reduction in Tg-MYOCY437H mice. Both treatments were associated with an upregulation in Mmp-9 expression while tPA also upregulated Mmp-13 expression. tPA increases the expression of matrix metalloproteinases and may cause extracellular matrix remodeling at the trabecular meshwork, which results in reversal of outflow facility reduction in Tg-MYOCY437H mice. The present study investigated the effects of anabolic steroid (AS) excess on blood pressure regulation. Male Wistar rats were treated with nandrolone decanoate (AS) or vehicle (CTL) for 8 or 10weeks. Saline (1.8%) and water intake were measured in metabolic cages. Urinary volume, osmolarity, Na and K concentrations, and plasma osmolarity were measured. The autonomic balance was estimated by heart rate variability at baseline or after icv injection of losartan. Cardiac function was assessed by echocardiography and ex vivo recordings. Myocardial collagen deposition was evaluated by Picrosirius-Red staining. Vascular reactivity and wall thickness were investigated in aortic sections. Blood pressure (BP) was assessed by tail-cuff plethysmography. Angiotensin II type I receptor (AT1R), renin, and mineralocorticoid receptor (MR) mRNA expression was measured in the kidneys and whole hypothalamus. AS group exhibited decreased urinary volume and Na concentration, while urinary K concentration, plasma osmolarity, and renal AT1R and renin mRNA levels were increased compared to CTL (p<0.05). Water intake was increased, and saline intake was decreased in the AS group (p<0.01). selleckchem AS group exhibited increased low-frequency/high-frequency-ratio, while it was decreased by icv injection of losartan (p<0.05) compared to baseline. Neither cardiac function nor vascular reactivity/morphology was affected by AS excess (p>0.05). Ultimately, BP levels were not altered by AS excess (p>0.05). AS excess promoted hydroelectrolytic and autonomic imbalance but did not alter vascular or cardiac function/morphology.
