PIERZYNOWSKI, T. SAHLU* AND S. P. HART E. (Kika) de la Garza Institute for Goat Research, Langston University, Langston, Oklahoma 73050, USA . IP address: (Received I1 November 1994 - Revised 15 March 1995 -Accepted I1 May 1995) 170.106.34.90 The effect of mimosine on a perfused area of skin tissue was studied using an isolated perfusion technique. Four mature Angora wethers (body weight 35 (SE 2.3) kg) were cannulated bilaterally with indwelling silicone catheters in the superficial branches of the deep circumflex iliac artery and vein. Mimosine , on (40 mg/kg metabolic weight (Wo75)per d) was infused intra-arterially into one iliac artery of each goat for 3 d and saline was infused in the contralateral (control) iliac artery. Iliac venous blood samples were 27 Sep 2021 at 22:01:16 taken from both sides along with arterial samples from the carotid artery. Mimosine infusion elevated plasma mimosine in the carotid artery (52.6 (SEM19.21) pol/l) and iliac vein on the saline-treated side to 54.1 (SEM 16-31)~ol/l and in the iliac vein on the mimosine-treated side to 191.3 (SEM1914) pmol/l (P < 0.01). Mimosine decreased feed intake (2.3 v. 0.6 kg/d, ~~~0.29;P < 0.001) and water consumption (5-2 v. 1.3 litres/d, SEM 0.67; P < 0.001). -
Review on the Nutritive Value and Toxic Aspects of Leucaena Leucocephala

Chemical analysis and feeding trial. have indicated that Leucaena leaf-meal with its high protein, calcium, -carotene and xanthophyll contents, is potentially a valuable feed for livestock in the tropics. The symptoms of mimosine toxicity in cattle, sheep, poultry, goats horses, pigs and rats ire discussed, The chemical value of mimosine and the possible mechanism of its toxicity are reviewed. Possible solutions to the toxicity problem are presented together with the suggestion that further studies be initiated to overcome this problem. Key Words: Leucaena, mimosine toxicity, livestock, forage, feeding trials The uses of the tropical legume Leucaena leucocephala are quite versatile. These uses include its function as a source of firewood and timber,its role in soil erosion control (Dijkman 1950), its ability to provide shade for other plants as well as its function in maintaining the fertility of the soil and of serving as a nutritious forage for animal feed (Ruskln 1977). Presently the greatest use of this plant in animal nutrition is its incorporation in cattle feed. Leucaena leaf-meal, with its rich protein, minerals and vitamin content, is also becoming a popular ingredient in poultry feeds in the tropics (D'Mello and Taplin 1978). -

New Markers in the Mycotox Profile
New Markers in the MycoTOX Profile We are happy to announce the addition of four new mycotoxin markers to our MycoTOX Profile. The test now includes 11 mycotoxins from 40 species of mold, making it by far the most comprehensive and competitively priced mycotoxin test available. It also still more sensitive and accurate than other tests available, because we use LC/MS/MS technology. Here is an overview of the four new mycotoxin markers: Gliotoxin Gliotoxin (GTX) is produced by the mold genus Aspergillus. Aspergillus spreads in the environment by releasing conidia which are capable of infiltrating the small alveolar airways of individuals. In order to evade the body’s defenses Aspergillus releases Gliotoxin to inhibit the immune system. One of the targets of Gliotoxin is PtdIns (3,4,5) P3. This results in the downregulation of phagocytic immune defense, which can lead to the exacerbation of polymicrobial infections. Gliotoxin impairs the activation of T-cells and induces apoptosis in monocytes and in monocyte-derived dendritic cells. These impairments can lead to multiple neurological syndromes. Mycophenolic Acid Mycophenolic Acid (MPA) produced by the Penicillium fungus. MPA is an immunosuppressant which inhibits the proliferation of B and T lymphocytes. MPA exposure can increase the risk of opportunistic infections such as Clostridia and Candida. MPA is associated with miscarriage and congenital malformations when the woman is exposed in pregnancy. Dihydrocitrinone Dihydrocitrinone is a metabolite of Citrinin (CTN), which is a mycotoxin that is produced by the mold species Aspergillus, Penicillium, and Monascus. CTN exposure can lead to nephropathy, because of its ability to increase permeability of mitochondrial membranes in the kidneys. -

Luteolin is one of the major bioactivity compositions in F. chrysanthemi Indici in JMT. There are some reports about pharmacokinetics of luteolin in extract of F. chrysanthemi and husks of peanut in normal rats, but it lacked pharmacokinetic information of luteolin residing in a Chinese herb compound prescription in hypertensive animal models. The present study aimed to develop a high-performance liquid chromatography with photodiode array detection (HPLC-DAD) method for determination of luteolin in rat plasma and for pharmacokinetic study after oral administration of JMT to spontaneous hypertensive rats (SHR) and normal Sprague Dawley (SD) rats. After oral administration of JMT to SHR and SD rats, respectively the content of luteolin in blood samples at different time points were determined by a reversed-phase high- performance liquid chromatography (RP-HPLC) coupled with liquid-liquid phase extraction. -
Antidepressant-Like Behavioral and Neurochemical Effects of the Citrus
Available online at www.sciencedirect.com Life Sciences 82 (2008) 741–751 www.elsevier.com/locate/lifescie Antidepressant-like behavioral and neurochemical effects of the citrus-associated chemical apigenin ⁎ Li-Tao Yi, Jian-Mei Li, Yu-Cheng Li, Ying Pan, Qun Xu, Ling-Dong Kong State Key Laboratory of Pharmaceutical Biotechnology, School of Life Sciences, Nanjing University, Nanjing 210093, PR China Received 14 July 2007; accepted 16 January 2008 Abstract Apigenin is one type of bioflavonoid widely found in citrus fruits, which possesses a variety of pharmacological actions on the central nervous system. A previous study showed that acute intraperitoneal administration of apigenin had antidepressant-like effects in the forced swimming test (FST) in ddY mice. To better understand its pharmacological activity, we investigated the behavioral effects of chronic oral apigenin treatment in the FST in male ICR mice and male Wistar rats exposed to chronic mild stress (CMS). The effects of apigenin on central monoaminergic neurotransmitter systems, the hypothalamic–pituitary–adrenal (HPA) axis and platelet adenylyl cyclase activity were simultaneously examined in the CMS rats. Apigenin reduced immobility time in the mouse FST and reversed CMS-induced decrease in sucrose intake of rats. Apigenin also attenuated CMS-induced alterations in serotonin (5-HT), its metabolite 5-hydroxyindoleacetic acid (5-HIAA), dopamine (DA) levels and 5-HIAA/ 5-HT ratio in distinct rat brain regions. Moreover, apigenin reversed CMS-induced elevation in serum corticosterone concentrations and reduction in platelet adenylyl cyclase activity in rats. These results suggest that the antidepressant-like actions of oral apigenin treatment could be related to a combination of multiple biochemical effects, and might help to elucidate its mechanisms of action that are involved in normalization of stress- induced changes in brain monoamine levels, the HPA axis, and the platelet adenylyl cyclase activity. -

However, a comprehensive review of plant-based anxiolytics has been absent to date. Thus, our aim was to provide a comprehensive narrative review of plant-based medicines that have clinical and/or preclinical evidence of anxiolytic activity. We present the article in two parts. In part one, we reviewed herbal medicines for which only preclinical investigations for anxiolytic activity have been performed. In this current article (part two), we review herbal medicines for which there have been both preclinical and clinical investigations for anxiolytic activity. -
Nicotine Induces Polyspermy in Sea Urchin Eggs Through a Non-Cholinergic Pathway Modulating Actin Dynamics

Received: 8 November 2019; Accepted: 21 December 2019; Published: 25 December 2019 Abstract: While alkaloids often exert unique pharmacological effects on animal cells, exposure of sea urchin eggs to nicotine causes polyspermy at fertilization in a dose-dependent manner. Here, we studied molecular mechanisms underlying the phenomenon. Although nicotine is an agonist of ionotropic acetylcholine receptors, we found that nicotine-induced polyspermy was neither mimicked by acetylcholine and carbachol nor inhibited by specific antagonists of nicotinic acetylcholine receptors. Unlike acetylcholine and carbachol, nicotine uniquely induced drastic rearrangement of egg cortical microfilaments in a dose-dependent way. Such cytoskeletal changes appeared to render the eggs more receptive to sperm, as judged by the significant alleviation of polyspermy by latrunculin-A and mycalolide-B. In addition, our fluorimetric assay provided the first evidence that nicotine directly accelerates polymerization kinetics of G-actin and attenuates depolymerization of preassembled F-actin. Furthermore, nicotine inhibited cofilin-induced disassembly of F-actin.
